*121 Before POWERS, KIDD and B.A. SMITH, JJ.
BEA ANN SMITH, Justice.
This case involves an interstate child support enforcement proceeding. Nancy Moreno sought Texas registration of a 1982 Colorado support order naming Robert Cowan as the obligor. Cowan filed a petition to vacate the registration on the ground that the Colorado decree is not a support "order" because it conditioned visitation rights on the payment of child support rather than ordering him unconditionally to make child support payments. After a hearing on the petition, the district court signed an order confirming registration of the Colorado support order but expressly declining to rule on the decree's enforceability.[1] Cowan appeals this order by one point of error, arguing that the trial court erred in denying his petition to vacate registration of a foreign support order because no support order had been presented to the court. We will dismiss for want of jurisdiction because the order is not a final judgment.

DISCUSSION
With certain exceptions, an appeal may be taken only from a final judgment of a district or county court. Tex.Civ.Prac. & Rem.Code Ann. § 51.012 (West 1986); North E. Indep. Sch. Dist. v. Aldridge, 400 S.W.2d 893, 895 (Tex.1966). A judgment is final when it determines the rights of all parties and disposes of all issues in a case so that no future action by the court is necessary to settle the entire controversy. Aldridge, 400 S.W.2d at 895; Wagner v. Warnasch, 156 Tex. 334, 295 S.W.2d 890, 892 (Tex.1956).
Cowan argues that the order is final because Moreno did not file a petition asking for enforcement of the Colorado decree. He contends that the only issue before the court was the registration of the support decree and that therefore the order confirming registration is final. We disagree because both Moreno's and Cowan's pleadings raised the issue of the enforceability of the order.
We initially decide whether the Revised Uniform Reciprocal Enforcement of Support Act (RURESA)[2] or the Uniform Interstate Family Support Act (UIFSA) applies to the registration of the Colorado judgment. Texas repealed RURESA effective September 1, 1993, and concurrently enacted UIFSA. See Tex.Fam.Code Ann. §§ 21.01.52 (West Supp.1995);[3]see also Act of May 8, 1993, 73d Leg., R.S., ch. 970, § 1, 1993 Tex.Gen.Laws 4212-35. Cowan points out that the legislation enacting UIFSA provides: "This Act takes effect September 1, 1993, and applies only to an order, decree, or judgment entered on or after that date." Id. at 4235. Cowan argues that the UIFSA does not apply to this cause because the Colorado decree was rendered on March 18, 1982. We disagree.
UIFSA is designed to streamline and expedite interstate and intrastate enforcement of support decrees. It addresses both the duties of the state that originally issues a decree, the "issuing state," and the state in which the obligee seeks to enforce a decree, the "responding state." Subchapter F of UIFSA addresses the Texas registration of foreign support orders when Texas is the responding state; it does not address the rendition of another state's support order. Also, if the legislature had intended to apply *122 UIFSA only to foreign support orders rendered after September 1, 1993, it could have left RURESA in place or continued RURESA in effect[4] because there would be a considerable time lag before foreign support orders rendered any time before September 1, 1993 would be registered for enforcement. Finally, we note that the language in section 16 is identical to the language used when RURESA was promulgated, which the legislature later clarified by providing that, when Texas was the responding state, the effective date is the date that the Texas court enters a judgment.[5] Since RURESA and UIFSA both serve the same purposeexpedited and uniform enforcement proceedingsthe same reasoning applies to section 16 of UIFSA. We conclude that with regard to Subchapter F, the date an order, decree, or judgment was "entered" refers to the date that the Texas court enters its judgment. Since the Colorado order was filed after UIFSA's effective date, the judgment entered in a UIFSA judgment and the procedure for obtaining that judgment is UIFSA procedure. See Tex.Fam.Code Ann. § 21.36 (West Supp. 1995). In this case, since the documents were filed on December 15, 1993, UIFSA applies.
We next consider whether enforcement of the decree was an issue in the confirmation proceeding. Moreno filed a standardized Uniform Reciprocal Enforcement of Support Act ("URESA") petition to register the support decree. Cowan claims that Moreno did not raise the issue of enforcement because she did not file a "motion to enforce" the decree as is necessary to initiate the enforcement of Texas support orders.[6]See Tex.Fam.Code Ann. § 14.31 (West Supp. 1995). We disagree.
Texas Family Code section 21.23 provides that the petition to establish[7] a support order must conform substantially with the requirements imposed by the forms mandated by federal law for use in cases filed by a support enforcement agency. Since neither party disputes this, we assume Moreno's standardized petition met the requirements of section 21.23.
Texas Family Code section 21.36(a) requires the submission of particular documents to register an order for enforcement in this state, including a letter of transmittal requesting registration and enforcement. On pages one and two of the uniform support petition, Moreno indicated by checking a preprinted box that she requested the collection and payment of arrears. Section 21.36(c) further provides that a "petition or comparable *123 pleading seeking a remedy that must be affirmatively sought under other law of this state may be filed at the same time as the request for registration or later." Tex.Fam. Code Ann. § 21.36(c) (West Supp.1995) (emphasis added). The commissioners' comment to the analogous uniform provision notes that "the authorization of a later request contemplates that interstate pleadings may be liberally amended to conform to local practice."[8] Uniform Interstate Family Support Act § 603, Comment, 9 U.L.A. 126, 157 (Supp.1994). Moreno has indicated that she seeks the payment of arrears; should Texas law require a particular petition or form to initiate a remedy, she could amend her petition to include such a document. As it is, her petition suffices to raise the issue of enforcement of arrearages.[9]
Moreover, although Cowan characterizes his petition to vacate registration as a challenge to the existence of a support decree, the trial court order characterized it as an argument regarding enforcement of the decree. We agree with the trial court's conclusion. A support order is a "judgment, decree, or order, whether temporary, final, or subject to modification, for the benefit of a child, a spouse, or a former spouse, that provides for monetary support, health care, arrearages, or reimbursement. . . ." Tex. Fam.Code Ann. § 21.01(21) (West Supp. 1995). The document the State seeks to register is a Colorado decree that provides:
And it is further ordered, adjudged, and decreed by the court that . . . [Cowan] shall [have] visitation rights conditioned upon his making child support payments of $100.00 per week to [Moreno] payable weekly beginning March 28, 1982.
The order, on its face, appears to be a valid order of a Colorado court. Under the Full Faith and Credit Clause, the introduction of a facially valid order of a foreign court creates a prima facie case for its proponent. Mitchim v. Mitchim, 518 S.W.2d 362, 364 (Tex.1975). A facially valid order may be challenged only on limited grounds such as a lack of personal jurisdiction by the issuing court, or some procedural defect that would render the decree void. Id.; Nunez v. Nunez, 771 S.W.2d 7, 9 (Tex.App.San Antonio 1989, no writ); O'Halloran v. O'Halloran, 580 S.W.2d 870, 873 (Tex.Civ.App.Texarkana 1979, no writ). The party challenging the decree bears the burden of proving that the judgment is void.[10]Mitchim, 518 S.W.2d at 364. Cowan did not raise any jurisdictional or procedural defects. "There is no defense. . . to the registration of a valid foreign support order." UIFSA § 606, Comment, 9 U.L.A. 126, 160 (Supp.1994). Since the order is a "decree . . . for the benefit of a child . . . that provides for monetary support," the order is a "support order" contemplated by UIFSA.
Basically, Cowan's pleading asserts that some or all of the asserted arrearages did not accrue because he did not exercise his *124 visitation rights. This issue relates to the enforceability rather than to the existence of the support order.
A judgment or order that expressly reserves an issue for later adjudication is interlocutory. Wilcox v. St. Mary's Univ. of San Antonio, Inc., 501 S.W.2d 875, 876 (Tex. 1973); Angerstein v. Angerstein, 389 S.W.2d 519, 521 (Tex.Civ.App.Corpus Christi 1965, no writ). Moreno's standardized URESA pleading indicates that she desires the collection of arrears and Cowan's own motion challenges the enforceability of the order. Accordingly, the issue must be resolved before the decree is final. See Zellers v. Barthel, 727 S.W.2d 364, 366 (Tex.App.Fort Worth 1987, no writ) (order granting wife's motion to increase child support not final since it expressly did not dispose of issue of visitation raised in husband's response to motion).
Cowan argues that any enforcement issues need not be resolved now, relying on cases involving decrees which were held to be final and appealable even though the judgment contemplated that a separate action might be taken for enforcement. See Ferguson v. Ferguson, 161 Tex. 184, 338 S.W.2d 945, 947 (1960). In those cases, the substantive rights of the parties had been settled and the only issue was enforcement. Here, the court expressly declined to rule on the merits of the petition and left unsettled the amount of accrued arrearages;[11] there are no liquidated damages that can be reduced to judgment.[12]
Accordingly, we dismiss the appeal for lack of jurisdiction.
NOTES
[1]  The order reads:

The Court does not rule on the issue of enforceability of the order as raised by paragraph I. of the PETITION TO VACATE THE REGISTRATION OF FOREIGN SUPPORT ORDER filed by Obligor.
[2]  Revised Uniform Reciprocal Enforcement of Support Act, 70th Leg., 2d C.S., ch. 49, sec. 1, 1987 Tex.Gen.Laws 145-52 (Tex.Fam.Code Ann. §§ 21.01-.43, since repealed).
[3]  The Uniform Interstate Family Support Act was recodified effective April 20, 1995 by H.B. 655. See Act of Apr. 6, 1995, 74th Leg., R.S., ch. 20, § 159.001-.902, 1995 Tex.Sess.Law Serv. 113, 195-208 (to be codified at Tex.Fam.Code Ann. §§ 159.001-.902). H.B. 655 provides: "The change in law made by this Act does not affect a proceeding under the Family Code pending on the effective date of this Act. A proceeding pending on the effective date of this Act is governed by the law in effect at the time the proceeding was commenced, and the former law is continued in effect for that purpose." Id. § 3. Therefore, we will analyze this cause under the prior codification of UIFSA.
[4]  Consider, for example, section 3 of H.B. 655, which provides that the former law "is continued in effect" because it applies to pending proceedings. Act of Apr. 6, 1995, 74th Leg., R.S., ch. 20, § 159.001-.902, 1995 Tex.Sess.Law Serv. 113, 195-208 (to be codified at Tex.Fam.Code Ann. §§ 159.001-.902).
[5]  RURESA originally provided that, "This Act takes effect November 1, 1987, and applies only to an order, decree, or judgment entered on or after that date." URESA, 70th Leg., 2d C.S., ch. 49, sec. 2, 1987 Tex.Gen.Laws 145, 158. In 1991, the legislature clarified that:

The amendment to Chapter 21, Family Code, made by Chapter 49, Acts of the 70th Legislature, 2d Called Session, 1987, applies to an order, decree, or judgment entered before, on, or after November 1, 1987, except that, if the court entering the order, decree, or judgment is a court of this state acting as the responding court, the amendment applies only to an order, decree, or judgment entered on or after November 1, 1987.
Act of May 26, 1989, 71st Leg., R.S., ch. 371, § 9, 1991 Tex.Gen.Laws 1462, 1466 (emphasis added).
[6]  Section 21.37(b) provides that a "registered order issued in another state is enforceable in the same manner and is subject to the same procedures as an order issued by a tribunal of this state." Tex.Fam.Code Ann. § 21.37(b) (West Supp.1995).
[7]  Although § 21.23 only refers to a petition to "establish" a support decree, we believe that the section applies to petitions to register an existing foreign support order as well as petitions seeking to establish an original order. First, § 21.23 is in Subchapter C, which contains the civil provisions of general application. See Tex.Fam.Code Ann. § 21.13(a) (West Supp.1995) ("Except as otherwise provided in this chapter, this subchapter applies to all proceedings under this chapter."). Second, it refers to the "obligor," a term that applies both to a person who owes a duty of support and a person who is liable under a support order. See id. § 21.01(13). Finally, the comments to the uniform section declare that it "establishes the basic requirements for the drafting and filing of interstate pleadings." UIFSA § 311, Comment, 9 U.L.A. 126, 147 (Supp.1994).
[8]  The intent of the drafters of the uniform bill is not binding but is highly persuasive because the Texas Legislature provided that UIFSA "shall be applied and construed to effectuate its general purpose to make uniform the law with respect to the subject of this chapter among states enacting it." Tex.Fam.Code Ann. § 21.50 (West Supp. 1995).
[9]  The drafters of UIFSA discussed the possibility of registration without a concurrent request for enforcement, which they termed "registration for the fun of it." See John J. Sampson, Uniform Interstate Family Support Act and Unofficial Annotations, 27 Fam.L.Q. 93, 151 n. 126 (1993). Theoretically, one could register a decree even if there is no arrearage. Id. The drafters of the uniform rules wrote: "Although registration not accompanied by a request for affirmative relief is not prohibited, the Act does not contemplate registration as serving a purpose in itself." UIFSA § 601, Comment, 9 U.L.A. 126, 156 (Supp. 1994). Ultimately, the drafters of UIFSA did not explicitly recognize registration without a concurrent request for enforcement, although they consider that possibility open. Id. Moreno's petition does not suggest that she is registering for any purpose other than enforcement.
[10]  Cowan argues that in a standard full faith and credit inquiry the burden would be on the proponent of a foreign order to prove that the order is valid, and that registration under UIFSA shifts the burden of proof to him to prove that the order is void. Cowan is mistaken; the burden of proving the order void always rests on the person opposing recognition of a foreign order. See Mitchim v. Mitchim, 518 S.W.2d 362, 364 (Tex. 1975); First Nat'l Bank v. Rector, 710 S.W.2d 100, 103 (Tex.App.Austin 1986, writ ref'd n.r.e.).
[11]  The Colorado agency that initiated this proceeding asserted arrearages due of $109,613.45 based on information Moreno supplied. However, due process requires that the amount of arrearages, if challenged, must be adjudicated by a registering state that has personal jurisdiction over the obligor. See Sampson, supra at 151 n. 126. Therefore, Cowan may challenge the amount of the arrearages by interposing any of the applicable defenses in Texas Family Code section 21.41(a).
[12]  The trial court's order states that it confirms only registration. UIFSA does not expressly authorize a proceeding in which registration rather than the order is confirmed. Under UIFSA, an order is registered when the order is filed with the registering tribunal. Tex.Fam.Code Ann. § 21.37(a), (b) (West Supp.1993). A party contesting either the validity or enforcement of a registered order must request a hearing within twenty days after the date of service of notice of the registration. Tex.Fam.Code Ann. § 21.40(a) (West Supp.1995). And, at the hearing, the party contesting either the validity or enforcement of an order has the burden of proving certain enumerated defenses. Id. § 21.41(a). The registering tribunal confirms the order, if, after notice and hearing, it finds that the nonregistering party did not establish a defense to either the validity or enforcement of the order. Id. § 21.41(c). Finally, UIFSA contains a type of "limitations" provision that RURESA did not: under UIFSA, "Confirmation of a registered order, whether by operation of law or after notice and hearing, precludes further contest of the order with respect to any matter that could have been asserted at the time of registration." Id. § 21.42 (emphasis added). The matters that could have been asserted at the time of registration are the defenses listed in § 21.41(a). Id. § 21.41(a)(1)-(7).

In sum, the nonregistering party may, if it acts within 20 days of the notice of registration, seek to vacate the registration, assert any defense to an allegation of noncompliance, or contest the remedies being sought or the amount of any alleged arrearages. See id. § 21.40(a), 21.41(a)(1)-(7). Confirmation of the order precludes further contest of any of those matters. Id. § 21.42; see also UIFSA § 608, Comment, 9 U.L.A. 126, 162 (Supp.1994) (disapproving of holding in In re Marriage of Chapman, 205 Cal. App.3d 253, 252 Cal.Rptr. 359 (1988), in which the court, interpreting RURESA, held that only terms of support order, and not amount of arrearages, had been confirmed by confirmation order).
