       Ruben F. appeals an order denying his petitions under Welfare and Institutions

Code section 3881 to vacate the jurisdictional and dispositional findings and orders of the

juvenile court. He contends he was denied his due process and statutory rights to notice,

including proper service under the Convention on the Service Abroad of Judicial and

Extrajudicial Documents in Civil or Commercial Matters (Nov. 15, 1965, 20 U.S.T. 361,

T.I.A.S. No. 6638) (Hague Service Convention or Convention), because the San Diego

County Health and Human Services Agency (Agency) did not conduct a reasonable

search for him. Ruben also contends the juvenile court erred when it required him to file

a petition under section 388 to challenge the alleged notice errors. We conclude that the

juvenile court erred in requiring Ruben to file a section 388 petition to consider whether

he received proper service under the Hague Service Convention but the error was

harmless. We otherwise find no error and affirm.

                  FACTUAL AND PROCEDURAL BACKGROUND

       Alberto F., now 12 years old, and D.V., now eight years old, are the children of

Ruben F. and Doreen E. Ruben is a Mexican citizen living in Mexico. Alberto and D.V.


1       Unless otherwise indicated, further statutory references are to the Welfare and
Institutions Code.
                                             2
(together, the children) lived with their mother and several of their older half siblings in

San Diego. Alberto and his older half siblings were juvenile court dependents from 2004

until 2010 because of Doreen's substance abuse problems and Ruben's physical and

verbal aggression toward her. D.V. was a juvenile court dependent from her birth in

2006 until 2010.

       The history of the children's first dependency proceedings is detailed in our

nonpublished opinions in In re Tatiana V. (Mar. 13, 2008, D051007, D051276); In re

Tatiana V. (June 2, 2009, D053584); In re T.V. (Oct. 5, 2009, D055144); and In re

Tatiana V. (Mar. 16, 2011, D057624). As relevant here, during those proceedings, Ruben

attained status as Alberto's presumed father and as D.V.'s biological father. He had a

criminal history, including drug-related charges, and was deported in 2005. Ruben

returned to the United States shortly after his deportation. He fathered D.V. but was

incarcerated at the time of her birth and subsequently deported in late 2008 or early 2009.

Ruben was represented by counsel during the first dependency proceedings. Doreen

regained custody of the children in 2008 and the court ultimately terminated jurisdiction

in 2010.

       On August 24, 2011, the Agency removed the children from Doreen's care because

of hazardous conditions in the home and Doreen's substance abuse problems. Doreen

told the social worker Ruben was living in Mexico. He had not visited with Alberto and

D.V., but had telephone contact with them. Doreen did not have his telephone number or

address. Doreen said Ruben's relatives, who lived in San Diego, may have his contact



                                              3
information. Doreen knew where the relatives lived in San Diego but did not know their

names, telephone numbers or addresses.

       On August 26, the Agency initiated a parent search for Ruben. The search

included local, state and federal agencies. On October 5, the social worker mailed a letter

to Ruben at his last known address in San Diego (C Street) advising Ruben there would

be a court hearing on October 122 concerning his children and asking him to contact her.

The social worker received a return receipt signed by Eva F. for the letter. Eva was later

identified as Ruben's great-aunt.

       The juvenile court took jurisdiction over the children and removed them from

Doreen's custody with family reunification services. The court made no findings as to

Ruben.

       Six months later, in April 2012, the social worker submitted parent search referrals

for Ruben to its International Liaison office and to its domestic search team.

International Liaison social worker Francisco Llerandi contacted the Mexican Consulate,

the Attorney General's Office, the Mexican social services agency and the Census Office

of Mexico. None of those agencies had any record of Ruben's whereabouts. On April

26, the social worker mailed a certified letter to Ruben at C Street advising him he had a

right to attend a court hearing on May 15 for his children and requesting that Ruben




2      The jurisdiction hearing was initially calendared for October 12, 2011, but was
heard on November 17, 2011.

                                             4
contact her if he did not want to be involved with the case.3 Another letter was sent to

Ruben at C Street on May 8.4 The social worker asked Alberto if he had talked with

Ruben recently. Alberto denied any contact, saying Ruben did not know his new

telephone number and he did not have Ruben's telephone number.

       In February 2013, the Agency recommended placing the children with Doreen

with family maintenance services. Because Doreen tested positive for amphetamine and

methamphetamine in March, the Agency changed its recommendation to termination of

reunification services and asked the juvenile court to set a section 366.26 hearing.

       The Agency submitted another parent search request for Ruben in February 2013.

The results indicated Ruben received mail at C Street. The social worker located

telephone numbers for six of Ruben's friends and relatives and telephoned them,

including Norma F., Ruben's aunt. A man who answered Norma's telephone said the

social worker had a wrong number. Ruben's grandfather said he did not know Ruben's

whereabouts. Another relative said he believed that Ruben had been deported to Mexico.

       In May and June, a protective services assistant went to C Street and left a

business card with a request for a return call. In July, on her third visit to C Street, the

assistant spoke to Ruben's aunt Norma. She did not have Ruben's address but provided

his telephone number to the assistant, who in turn gave Ruben's telephone number to

social worker Llerandi. Llerandi telephoned Ruben, who was living in Rosarito, B.C.,

Mexico, and obtained his address.

       At Llerandi's request, a paternal relative delivered a copy of the notices for the

children's section 366.26 hearing to Ruben. Ruben signed the documents on July 19. He

told Llerandi he did not know his children's cases were nearing the end. He said Doreen

never contacted him and he had many family members who could care for Alberto and

D.V. Ruben requested counsel be appointed to represent him.

       Social worker Cathy Andrews sent an Attorney Appointment Request to Ruben by

mail to his address in Rosarito. The Agency received a signed waiver and proof of

service from Ruben the following week.

       In August, the Agency asked the juvenile court to continue the section 366.26

hearing for 180 days to allow it to identify an appropriate permanent placement for

Alberto, D.V. and their older half sister, Tatiana, as a sibling group. On October 23,

Ruben's counsel filed a motion to vacate the 2011 jurisdictional findings and orders the

juvenile court had made on behalf of Alberto and D.V. He asserted he did not receive

adequate notice of the children's dependency proceedings. Ruben argued the Agency

failed to search for him in Mexico; did not attempt to contact Eva, who had signed a

return receipt for a letter mailed to Ruben's last known address on C Street before the

jurisdiction hearing; did not serve Ruben with the children's section 300 petitions; did not

provide adequate notice of the section 366.26 hearing; and did not comply with the

Hague Service Convention.



                                              6
       Over Ruben's objections, the juvenile court required him to file a section 388

petition before it would consider whether he received adequate notice of the proceedings.

The court said Ruben had the burden of showing that vacating the jurisdiction hearing

was in the children's best interests.

       Ruben filed section 388 petitions alleging he did not receive proper notice of the

children's dependency proceedings and that it was in the children's best interests to vacate

the jurisdictional and dispositional findings to obtain a dependency adjudication based

upon all material facts and circumstances, and the participation of all interested parties

entitled to notice.

       D.V. and Alberto supported Ruben's petitions, stating they wanted to maintain

their relationships with their father.

       At the evidentiary hearing on Ruben's section 388 petitions, the juvenile court

admitted the Agency's report detailing its search efforts for Ruben, as described above.

The Agency acknowledged it did not conduct an international search for Ruben before

the jurisdiction and disposition hearing. However, the Agency noted it searched for

Ruben in Mexico in April, June and October 2012, contacted Mexican authorities and

made a media announcement in Mexico. None of those efforts were successful in

locating Ruben.

       Social worker Andrews, who was assigned to the children's cases after the juvenile

court referred the matter for a section 366.26 hearing, testified about her efforts to locate

Ruben. Andrews asked an assistant to visit the C Street address because it was the only

address the Agency ever had on file for Ruben and someone with the same last name as

                                              7
his lived there. On her third visit, the assistant obtained Ruben's telephone number from

his aunt Norma. A short time later, social worker Llerandi asked a paternal relative to

serve Ruben with notice of the section 366.26 hearing.

       Ruben's aunt Norma testified she had lived at C Street for eight years. Ruben's

great-aunt Eva also lived at that address. Ruben was deported to Mexico approximately

five years earlier and Norma had been in contact with him the entire time. Norma said

Ruben did not have a permanent address in Mexico, landline or a permanent cell phone

number and, for a while, he had been in a rehabilitation center in Tijuana, B.C. The aunt

testified Ruben also stayed at his girlfriend's house or with friends in Tijuana or Rosarito.

Although Ruben moved frequently, he always remained in contact with Norma, who

brought food, money and clothing to him every week or two. In October 2011, Norma

received a letter addressed to Ruben from the Agency. She acknowledged she took all

Ruben's mail to him.

       The juvenile court rejected Ruben's argument the search efforts were unreasonable

because the Agency did not immediately search for him in Mexico. The court noted the

record showed that in the previous dependency case, Ruben had returned to the United

States after being deported in 2005, and thus the domestic search was reasonably

calculated to lead to information about his current whereabouts. The juvenile court said

the more important issue was whether the modification requested was in the children's

best interests. The court found that Ruben had not met this burden, noting that even after

he talked with the social worker and learned of his children's circumstances, he made no

effort to contact the children. The juvenile court found that the Agency's search efforts

                                              8
were reasonable and denied Ruben's section 388 petitions. The court further found that

Ruben had actual notice of the children's dependency proceedings.

       The juvenile court directed the Agency to comply with the Hague Service

Convention for notice of the section 366.26 hearing as expeditiously as possible, and

continued the section 366.26 hearing for approximately two months.

       On March 27, 2014, the date set for the section 366.26 hearing, the Agency asked

the court to reconsider its order to comply with the Hague Service Convention and find

that service under the Convention was not required. The court directed the Agency to file

a section 388 petition.

       In support of its section 388 petition, the Agency reported it had tried to comply

with the order to serve Ruben in compliance with the Hague Service Convention by

researching the law, consulting the Los Angeles County Counsel and the United States

Department of Justice (DOJ), and implementing a procedure to comply with the

Convention's requirements. According to the DOJ, the Convention was not commonly

applied to juvenile dependency matters. Service through Mexican authorities could take

from four months to more than a year. The Agency stated it had prepared the court

documents required by Mexico under the Convention and had mailed them to the

California Secretary of State. Once the documents were returned, the Agency would then

forward the documents to the Mexican Ministry of Foreign Affairs. The Agency

estimated it would take seven more months to serve Ruben in accordance with the Hague

Service Convention.



                                             9
      Minor's counsel advised the juvenile court Alberto now wished to be adopted by

his foster care parents. D.V., who was placed with her maternal grandmother, did not

change her position about maintaining her relationship with Ruben.

      On April 11, 2014, the juvenile court found that the children's best interests

required compliance with the Hague Service Convention and denied the Agency's section

388 petition.5 The juvenile court continued the section 366.26 hearing until December 9,

2014. This court, on its own motion, stayed the section 366.26 hearing until further

order.6




5     The Agency filed a notice of appeal of the juvenile court's order to comply with
the Hague Service Convention but did not pursue the appeal.

6       This court directed the parties to file supplemental simultaneous letter briefs
addressing whether "notice to a parent who is a Mexican [resident] of his or her child's
juvenile dependency proceeding under the Hague Service Convention (T.I.A.S. No. 6638
(U.S. Treaty)) [is] required in view of the Vienna Convention on Consular Relations
(T.I.A.S. No. 6820 (U.S. Treaty) and the Memorandum of Understanding Between the
Consulate General of Mexico in San Diego California and the County of San Diego
Health and Human Services Agency, State of California of the United States of America
Regarding Consular Assistance in Cases of Custody Involving Mexican Minors?"
        Based on these supplemental briefs and our own research, we have determined
there may be merit to the view that compliance with the Vienna Convention on Consular
Relations and the Memorandum of Understanding Between the Consulate General of
Mexico in San Diego may comport with, or replace, requirements for service under the
Hague Service Convention. (See, generally, In re Jennifer O. (2010) 184 Cal.App.4th
539, 547 [questioning whether the Hague Service Convention applies in dependency
proceedings].) However, the record in this case is not adequate to resolve the issue.
Accordingly, nothing in this opinion is to be construed as preventing the Agency from
clarifying the requirements imposed by Mexico for service of notice of a juvenile
dependency proceeding to a parent who is living in Mexico, particularly in a border
region. (See, e.g., Office of the Assistant Secretary for Planning and Evaluation et al.,

Foster Care: Collaborations with Foreign Consulates (Dec. 2013) p. 1.)

                             THE PARTIES' CONTENTIONS

       Reuben contends the jurisdiction and disposition hearings are void for lack of

personal jurisdiction over him. He argues the Agency deprived him of his right to seek

custody or reunify with his children by failing to conduct a reasonable search for him.

He asserts he did not receive proper service under the Hague Service Convention or

California statutory law, which requires that a parent be served with a copy of his child's

section 300 petition and a statement of rights. (§ 290.2.) Ruben contends there is not

substantial evidence to support the juvenile court's findings the Agency exercised due

diligence in searching for him and that he had actual notice of the dependency

proceedings. He maintains that the juvenile court erred when it required him to file a

section 388 petition to challenge the alleged notice errors under state law and the Hague

Service Convention. Doreen and D.V. join with Ruben's arguments.

       The Agency argues the juvenile court did not err in finding that service under the

Hague Service Convention was not required because Ruben's address was unknown. It

contends the juvenile court did not abuse its discretion in finding the Agency used

reasonable diligence to locate Ruben and that he had actual notice of the proceedings.

The Agency asserts the use of a section 388 petition is the proper means by which to

challenge jurisdiction based on an alleged notice error. Finally, the Agency argues

Ruben's due process rights were protected by the safeguards that are inherent in the

juvenile court's review of a section 388 petition.

                                             11
                                              B

                          APPLICABLE LEGAL PRINCIPLES

1.     Due Process

       Due process requires "notice reasonably calculated, under all the circumstances, to

apprise interested parties of the pendency of the action and afford them an opportunity to

present their objections." (Mullane v. Central Hanover Bank & Trust Co. (1950) 339

U.S. 306, 314; In re Claudia S. (2005) 131 Cal.App.4th 236, 247 (Claudia S.).) "Notice

is both a constitutional and statutory imperative. In juvenile dependency proceedings,

due process requires parents be given notice that is reasonably calculated to advise them

an action is pending and afford them an opportunity to defend." (In re Jasmine G. (2005)

127 Cal.App.4th 1109, 1114.)

       When a section 300 petition is filed, the clerk of the juvenile court is required to

issue notice by attaching a copy of the petition and causing it to be served on the parents.

(§ 290.2.) When a parent is not present at the detention hearing, the parent must receive

notice of the jurisdiction and disposition hearings by personal service or certified mail,

return receipt requested. (§ 291, subd. (e)(1); In re Alyssa F. (2003) 112 Cal.App.4th

846, 853 (Alyssa F.).)

       If the whereabouts of a parent is unknown, the child welfare agency must act with

diligence to locate a missing parent. Reasonable diligence denotes a thorough, systematic

investigation and an inquiry conducted in good faith. (David B. v. Superior Court (1994)

21 Cal.App.4th 1010, 1016 (David B.).) Where the party conducting the investigation

ignores the most likely means of finding the parent, the service is invalid even if the

                                             12
affidavit of diligence is sufficient. (Ibid.) However, "[d]ue process notice requirements

are deemed satisfied where a parent cannot be located despite a reasonable search effort

and the failure to give actual notice will not render the proceedings invalid." (Claudia S.,

supra, 131 Cal.App.4th at p. 247.)

       Unless there is no attempt to serve notice on a parent, in which case the error is

reversible per se, notice errors do not automatically require reversal but are reviewed to

determine whether the error is harmless beyond a reasonable doubt. (In re J.H. (2007)

158 Cal.App.4th 174, 182-183.) A parent claiming a lack of due process notice of a

juvenile dependency petition can challenge the judgment by filing a section 388 petition

in the same proceeding. (Ansley v. Superior Court (1986) 185 Cal.App.3d 477, 481 [a

judgment void for lack of due process notice is subject to attack at any time in a

proceeding initiated for that purpose].) Alternatively, a parent can apply to "the inherent

power of the court which exists independent of any statute to set aside judgments void for

want of jurisdiction over the person." (David B., supra, 21 Cal.App.4th at pp. 1018,

1019-1020.)

2.     The Hague Service Convention

       Where a parent is a resident of another country that is a signatory to the Hague

Service Convention, the petition and notice of jurisdiction and disposition hearings must

be served on the parent pursuant to the Convention's requirements.7 (In re Jennifer O.,



7      "The Convention deals primarily with the transmission of documents from one
State to another State; the Convention does not address or comprise substantive rules
relating to actual service of process." (Practical Handbook on the Operation of the
                                             13
supra, 184 Cal.App.4th at p. 547.) The Hague Service Convention applies when the

forum state's internal law requires transmittal of documents as a necessary part of service

of process. (Volkswagenwerk Aktiengesellschaft v. Schlunk (1988) 486 U.S. 694, 700

(Volkswagenwerk); see §§ 290.2, 291 [requiring a copy of the petition to be served on the

parents].) The term "[s]ervice of process" refers to "a formal delivery of documents that

is legally sufficient to charge the defendant with notice of a pending action."

(Volkswagenwerk, at p. 700).)

       "The primary innovation of the Convention is that it requires each state to

establish a central authority to receive requests for service of documents from other

countries. 20 U.S.T. 362, T.I.A.S. 6638, Art. 2. Once a central authority receives a

request in the proper form, it must serve the documents by a method prescribed by the

internal law of the receiving state or by a method designated by the requester and

compatible with that law. Art. 5. The central authority must then provide a certificate of

service that conforms to a specified model. Art. 6. A state also may consent to methods

of service within its boundaries other than a request to its central authority. Arts. 8-11,

19. The remaining provisions of the Convention that are relevant here limit the

circumstances in which a default judgment may be entered against a defendant who had

to be served abroad and did not appear, and provide some means for relief from such a

judgment. Arts. 15, 16." (Volkswagenwerk, supra, 486 U.S. at pp. 698-699.)



Hague Convention of 15 November 1965 on the Service Abroad of Judicial and
Extrajudicial Documents in Civil or Commercial Matters (3d ed. 2006) p. XXV (Practical
Handbook).)
                                             14
        In addition to service through a central authority, the Hague Service Convention

permits service directly through its diplomatic or consular agents, or by mail, unless a

state objects. (Convention, arts. 8, 9; 3 Witkin, Cal. Procedure (5th ed. 2008) Actions,

§ 1005, p. 1222.) Mexico has objected to the use of those channels for service on its own

citizens. (Modificanciones a las Declaraciones del Gobierno de las Estados Unidos

Mexicanos al Convenio sobre la Notificacíon o Traslado en el Estranjero de Documental

Judicales o Extrajudiciales en Mataeria Civil o Comercial, adoptado en La Haya, el 15 de

noviembre de 1965, par. V (Declaration 2011); see Campbell, No Sirve Continued:

Mexico Modifies Its Declarations to the Hague Service Convention (2011) 20 Minn. J.

Intl. L. 1, 7.) Service on a Mexican citizen resident can only be accomplished through

the Mexican Central Authority. (In re Vanessa Q. (2010) 187 Cal.App.4th 128, 134-

135.)

        Where the Hague Service Convention applies to a parent, the failure to properly

serve that parent "renders all subsequent proceedings void as to that person." (Alyssa F.,

supra, 112 Cal.App.4th at p. 852.) Defective service of the petition and notice to appear

is not cured by actual notice of the action.8 (Ibid.; Floveyor Internat., Ltd. v. Superior

Court (1997) 59 Cal.App.4th 789, 794 [failure to comply with the Convention renders


8       "Nonetheless, defective service is not fatal to personal jurisdiction if the defendant
consents to jurisdiction over him or her by making a general appearance in the action."
(In re Vanessa Q., supra, 187 Cal.App.4th at p. 135.) For this reason, where the Hague
Service Convention applies, the better practice is, in addition to complying with the
Convention, to attempt notice to the parent through other means, such as mail or through
a relative and by notifying the Mexican Consulate, with the expectation that in the
majority of cases, a parent who is concerned about his or her child's well-being will want
to promptly appear and participate in his or her child's dependency proceeding.
                                             15
service void, even if defendant has actual notice of the lawsuit].) The burden is on the

plaintiff to show that service of process on the defendant "comported with the Hague

Convention regarding service on an individual in a foreign country, or a proper basis for

why the Hague Convention did not apply." (Lebel v. Mai (2012) 210 Cal.App.4th 1154,

1160 (Lebel).)

       The Hague Service Convention does not apply where the address of the person to

be served is not known. (Convention, art. 1; Lebel, supra, 210 Cal.App.4th at p. 1161.)

A plaintiff is required to exercise reasonable diligence to ascertain a defendant's

whereabouts. (Lebel, at pp. 1161-1162.) "No bright-line rule or singular test can be

articulated identifying or quantifying what good faith efforts would amount to a proper

showing of reasonable diligence" in ascertaining the whereabouts of a defendant for

purposes of service in compliance with the Hague Service Convention. (Id. at p. 1162.)

"Such a determination necessarily would have to be made on a case-by-case basis—a

factual inquiry appropriately left to resolution in the trial court."9 (Ibid.)




9       For the purposes of this appeal, we will assume, without deciding, that
" 'reasonable diligence' " to locate a missing defendant under the Hague Service
Convention is the equivalent of the requirement the Agency exercise " 'reasonable
diligence' " to search for a parent whose whereabouts are unknown. (See David B.,
supra, 21 Cal.App.4th at p. 1016.)

THE JUVENILE COURT ERRED IN REQUIRING RUBEN TO FILE A SECTION 388
   PETITION TO CHALLENGE AN ALLEGED NOTICE ERROR UNDER THE
                   HAGUE SERVICE CONVENTION

       A parent may use a section 388 petition to raise a due process notice error.

(Ansley v. Superior Court, supra, 185 Cal.App.3d at p. 481; David B., supra, 21

Cal.App.4th at p. 1018.) Although provisions of the Code of Civil Procedure relating to

the setting aside of default judgments do not apply to dependency proceedings, a parent

may also bring a motion to vacate a void judgment pursuant to the court's inherent

power.10 (David B., at pp. 1018-1019.)

       Under section 388, the burden is on the parent to show changed circumstances or

new evidence, and that the best interests of the child will be promoted by a modification

of the prior order. (§ 388.) " '[S]ection 388 contemplates that a petition make a prima

facie showing of both elements to trigger an evidentiary hearing on the petition.'

[Citation.] The statutory language 'makes clear that the hearing is only to be held if it

appears that the best interests of the child may be promoted by the proposed change of

order.' " (In re Justice P. (2004) 123 Cal.App.4th 181, 191.)

       It is not appropriate to deny a parent a hearing under section 388 where the parent

states a prima facie case that his constitutional right to notice has been violated. The

right to notice is "[a]n elementary and fundamental requirement of due process in any


10     The juvenile court has no authority to set aside an order for lack of personal
jurisdiction over a parent after parental rights have been terminated. (David B., supra, 21
Cal.App.4th at pp. 1019-1020.) We need not reach the issue whether this holding is
abrogated by the terms of the Hague Service Convention.
                                             17
proceeding which is to be accorded finality . . . ." (Mullane v. Central Hanover Bank &

Trust Co., supra, 339 U.S. at p. 314.) In addition, the juvenile court has "strong interests

in receiving all relevant information about the child's circumstances and avoiding an

erroneous decision based on untested evidence." (In re J.F. (2011) 196 Cal.App.4th 321,

335.) However, the juvenile court "must look to the totality of a child's circumstances

when making decisions regarding the child." (In re Chantal S. (1996) 13 Cal.4th 196,

201.) A modification of a jurisdictional or dispositional order may implicate the best

interests of the child, particularly where intervening review hearings have occurred, and it

does not violate due process to require a parent to show that the modification sought is in

the best interests of the child in view of the circumstances of the child and the posture of

the dependency proceedings. Thus, where a parent challenges notice on a due process

ground, the court does not err in requiring the parent to file a section 388 petition where

the modification sought implicates the child's best interests.

       However, where, as here, the parent challenges whether the court has personal

jurisdiction over him because of an alleged failure to comply with the Hague Service

Convention, a different consideration applies. Whereas the burden of proof in a section

388 petition is on the parent, the Hague Service Convention requires the plaintiff to show

service of process on the defendant comported with its provisions, or a proper basis for

why the Convention did not apply. (Lebel, supra, 210 Cal.App.4th at p. 1160.) State

courts must apply the provisions of a treaty as a matter of federal law. (Cf. Sanchez-

Llamas v. Oregon (2006) 548 U.S. 331, 346-347 [where a treaty provides for a particular

judicial remedy, courts, including state courts, must apply the remedy as a requirement of

                                             18
federal law].) Because it is the Agency's burden, as plaintiff, a parent cannot be required

to bear the burden of proof to establish the error or condition a hearing on a prima facie

showing of the child's best interests.11 Under the Hague Service Convention, the failure

to properly serve the parent "renders all subsequent proceedings void as to that

person."12 (Alyssa F., supra, 112 Cal.App.4th at p. 852, italics added.) Thus the

juvenile court erred when it required Ruben to file a section 388 petition to show he did

not receive service as mandated by treaty.

       However, the finding of error does not mandate reversal.13 (See People v. Flood

(1998) 18 Cal.4th 470, 493 [per se reversal reserved for structural flaws such as total

deprivation of the right to counsel, biased judge, unlawful racial exclusion of jury

members and denial of right of self-representation].) Therefore, to show prejudice,

appellant must show there is a reasonable probability the court would have reached a

more favorable result in the absence of the error. (People v. Watson (1956) 46 Cal.2d

818, 836.) As we explain, Ruben does not meet that standard because the record shows


11     The Agency contends that under article 12 of the Hague Service Convention, the
juvenile court is not required to deviate from section 388 when seeking to set aside prior
juvenile court orders. However, article 12 concerns costs of service. It does not address
procedural issues.

12     Thus, had Ruben established a notice violation, he would have been entitled to a
hearing to attain status as D.V.'s presumed father, request custody of the children under
section 361.2, and respond to the Agency's recommendation he not receive reunification
services. (§ 361.5, subds. (a), (c); see In re Drake M. (2012) 211 Cal.App.4th 754, 762-
763 [describing when a parent can challenge jurisdictional findings based on the conduct
of the other parent].)

13     Ruben was not denied a hearing on the merits of his petitions.
                                             19
that had the Agency been held to its burden of proof, it would have clearly shown that it

conducted a reasonable search for Ruben before the jurisdiction and disposition hearings

and his address was unknown; therefore, the Hague Service Convention did not apply.

                                             D

   THE COURT DID NOT ERR WHEN IT DETERMINED THAT THE AGENCY'S
           EFFORTS TO LOCATE RUBEN WERE REASONABLE;
           RUBEN WAS NOT DENIED DUE PROCESS OF LAW14

       Ruben contends the Agency did not conduct a reasonable search for him because

they did not look for him in Mexico until after the jurisdiction and disposition hearings,

and did not contact his relatives until July 2013.

       We review a due process notice issue as a mixed question of law and fact in which

we defer to the juvenile court's findings of historical fact under the substantial evidence

standard of review and determine a due process violation under the de novo standard of

review. (Cf. People v. Alvarez (1996) 14 Cal.4th 155, 182 [review of search and seizure

issue]; see In re J.H., supra, 158 Cal.App.4th at p. 183 [constitutional issues reviewed de

novo].)

       The record contains substantial evidence to support the juvenile court's factual

findings concerning the Agency's efforts to locate Ruben and that Ruben had actual


14     For purposes of this opinion, we assume, without deciding, that a notice violation
under the Hague Service Convention violates due process. (See Shoei Kako Co. v.
Superior Court (1973) 33 Cal.App.3d 808, 820 ["Article 15 of the convention is the
equivalent of our national due process concept, and it was so recognized in the Senate."],
citing Cong. Rec., Senate proceedings (Apr. 13, 1967) p. 404.) Article 15 requires the
judge not to give judgment until it has been established that the document was served in
accordance with the formal requirements of the requesting state in sufficient time to
enable the defendant to defend. (Practical Handbook, supra, at p. 97.)
                                             20
notice of his children's dependency proceedings. The record shows that Ruben was

living or incarcerated in San Diego from at least 2002 to March 2005, when he was

deported to Mexico. He returned to the United States shortly after he was deported.

Ruben's last known address was on C Street and someone with the same last name still

lived at that address. Although Doreen told the social worker Ruben was living in

Mexico when the children were detained in August 2011, Doreen did not have his

address or telephone number, and she did not know the names or addresses of his

relatives. The social worker submitted a standard parent search request for Ruben before

the detention hearing.

       We do not agree with Ruben's contention that the Agency's action in submitting a

parent search request to local and domestic agencies was unreasonable. The record

permits the reasonable inference that after his deportation, Ruben returned to the United

States no later than October 2005.15 The record also shows that Ruben was deported

sometime between November 2008 and May 2009 and he had a history of crossing the

United States-Mexico border and living in San Diego. Under these circumstances, it was

reasonable for the Agency to submit a domestic parent search referral to try to obtain

information that would lead to the discovery of Ruben's whereabouts. That effort, in fact,

resulted in the delivery of a letter from the Agency to Ruben by Ruben's aunt Norma,

who saw Ruben every week or every other week and delivered Ruben's mail to him in



15     D.V. was born in July 2006. During this time, Doreen's other children were
dependents of the juvenile court. Doreen was living in San Diego and engaging in
reunification services.
                                            21
Mexico. The jurisdiction and disposition hearing was held approximately six weeks after

the date of the Agency's letter. Ruben did not respond to the social worker's request to

contact her about his children. Ruben's later comment that he did not know the children's

dependency cases were "coming to an end" indicates he knew about the proceedings, and

supports the court's finding that Ruben had actual notice of the proceedings.

       In addition, we are not persuaded by Ruben's argument the Agency's later success

in locating Ruben through his relatives shows that the Agency's initial search for him was

deficient. The social worker telephoned several of Ruben's relatives, with no success.

The assistant went to the C Street address three times before she found someone who

would respond to her inquiries. Instead of supporting Ruben's argument, the Agency's

later success shows that it made substantial efforts to locate Ruben, despite the lack of

cooperation from his relatives. Ruben does not show that had the assistant visited the C

Street address prior to the jurisdiction and disposition hearing, the Agency would have

discovered his whereabouts.

       Similarly, we are not persuaded by Ruben's argument the Agency's search for him

was unreasonable because it did not search for him in Mexico prior to the jurisdiction and

disposition hearing. The Agency's unsuccessful international search efforts in April, June

and October 2012 support a reasonable inference that an international search in

September and October 2011 would not have resulted in the discovery of Ruben's

whereabouts. The searches were unsuccessful in locating Ruben, which was not

surprising in view of his aunt's testimony that he did not have a permanent address or

telephone and stayed with other people in various locations in Baja California. Thus, to

                                             22
the extent the Agency should have initiated an international search for Ruben before the

jurisdiction and disposition hearing, any error is harmless. (Justice P., supra, 123

Cal.App.4th at p. 193 [unless there is no attempt to serve notice on a parent, in which

case the error is reversible per se, due process violations in dependency proceedings are

subject to the "harmless beyond a reasonable doubt" standard of prejudice].)

       We conclude that the Agency conducted a reasonable search to locate Ruben and

the inquiry was made in good faith. (David B., supra, 21 Cal.App.4th at p. 1016.) Due

process notice requirements are deemed satisfied where a parent cannot be located

despite a reasonable search effort and the failure to give actual notice will not render the

proceedings invalid." (Claudia S., supra, 131 Cal.App.4th at p. 247.) In addition, the

Hague Service Convention does not apply where the address of the person to be served is

not known, a parent's address is unknown and the plaintiff has exercised reasonable

diligence to ascertain that person's whereabouts. (Lebel, supra, 210 Cal.App.4th at

pp. 1161-1162.)

       The juvenile court's ruling that a party must file a section 388 petition to challenge

an alleged notice error under the Hague Service Convention is reversed. In all other

respects, the findings and orders of the juvenile court are affirmed. The stay issued

November 20, 2014, of the section 366.26 hearing is vacated.
