OPINION DENYING REHEARING
JAMES T. WORTHEN, Chief Justice.
The Texas Department of Protective and Regulatory Services filed a motion for rehearing which is denied. However, the previous opinion delivered on May 30, 2003 is withdrawn, and the following opinion is substituted therefor.
Steven Gunnels ("Gunnels") appeals the termination of his parental rights. In his sole issue, Gunnels argues that the trial court erred in denying his motion to dismiss. We reverse and remand in part and affirm in part.


*227 BACKGROUND

On December 8, 2000, an infant, later identified as D.D.M., was found abandoned in a vehicle parked outside a fast-food restaurant in Canton, Texas. On the same day, the Texas Department of Protective and Regulatory Services (the "Department") was appointed temporary sole managing conservator of D.D.M. Subsequently, the Department discovered that D.D.M.'s mother, Misti Michelle Mayo, had been murdered the day before the child was abandoned. Further, Gunnels was identified as D.D.M.'s alleged father and later located by the Department. On December 20, 2000, the Department filed an amended petition for protection of a child, conservatorship and termination of Gunnels' parental rights in a suit affecting the parent-child relationship ("SAPCR").
On November 29, 2001, a hearing was conducted. The Department requested an extension of time beyond the one-year dismissal deadline[1] and, as grounds, acknowledged that the parties were waiting for blood to be redrawn to determine if Gunnels was the father of D.D.M. The court stated, "We'll extend it for six months." Neither Gunnels nor D.D.M.'s attorney ad litem objected. The court reset the case for December 18, 2001. Further, the court stated that, if paternity testing determined that Gunnels was not the father of D.D.M., the case would be tried on December 18. However, the court declared that, if Gunnels was determined to be D.D.M.'s father, a pre-trial hearing would be held on December 18. The judge's oral pronouncements were never formally memorialized and filed with the court.
On January 2, 2002, paternity testing determined that Gunnels was the father of D.D.M. Further, on March 18, 2002, Michael and Shannon Monk (the "Monks") filed a petition in intervention for conservatorship of D.D.M. The Monks are D.D.M.'s foster parents. On April 17, 2002, the Monks amended their petition for intervention to include a request for termination of Gunnels' parental rights.
On April 29, 2002, a jury trial was held. Before trial, Gunnels filed a motion to dismiss under section 263.401 of the Texas Family Code.[2] Gunnels declared that the dismissal date for this case was Monday, December 10, 2001. As of the trial date, Gunnels contended, the court had not rendered a final order according to section 263.401 nor an order granting a 180-day extension which complied with section 263.401(b).[3] Therefore, Gunnels argued that the suit should be dismissed without prejudice. The court denied Gunnels' motion to dismiss. However, before testimony in the trial began, the court discussed Gunnels' motion to dismiss and acknowledged that his motion was timely filed and, subsequently, denied. Nonetheless, the court admitted that the sufficiency of the six-month extension granted at the hearing *228 on November 29, 2001 might be in question. The judge decided to review the record but determined that the trial should proceed.
The following day, April 30, 2002, the court again discussed the November 29 hearing. On the record, the court took judicial notice of the proceedings and pronouncements reflected by the reporter's notes on November 29, 2001. The court ordered the clerk to file the original statement of facts from the November 29 proceedings. Further, the court noted that the record failed to memorialize the November 29 hearing on the docket sheet or through a written order. The court found that, although the proceedings of November 29 were not memorialized due to a stenographic error, an extension of time was rendered on that date. The court reiterated that the extension was for six months and that the trial was set for December 18, 2001. Further, the court noted Gunnels' objection that the November 29 proceedings did not comply with the requirements for an extension under section 263.401 and were not reduced to writing.
Consequently, on April 29, 2002, the court signed a Nunc Pro Tunc Order, which stated that the November 29 order was rendered but not memorialized by the court because of a stenographic error. Further, the order declared that the court had continuing jurisdiction of the suit, that it was in the best interest of the child that the Department should remain temporary managing conservator, that an extension of the dismissal date should be granted, and that temporary orders for the safety and welfare of the child were necessary to avoid further delay in resolving the suit. Finally, the order declared that the new dismissal date was June 10, 2002, and that the suit was set for trial on December 18, 2001.
Subsequently, the trial on the merits concluded and, on April 30, 2002, the jury found that the parent-child relationship between Gunnels and D.D.M. should be terminated. On May 1, 2002, the court ordered that the parent-child relationship between Gunnels and D.D.M. be terminated. Moreover, the court appointed the Department as permanent managing conservator of D.D.M. after finding the appointment was in the best interest of the child. This appeal followed.

EXTENSION OF DISMISSAL DATE
In his sole issue, Gunnels argues that the trial court's November 29 oral order does not meet the requirements for an extension of the one-year dismissal date under section 263.401(b). Because the order is defective, Gunnels asserts, the statute permits no action other than a dismissal of the case after the one-year deadline. Thus, Gunnels contends that the trial court erred when it denied his motion to dismiss. The Department argues that the oral order is valid although it was not reduced to writing and may technically fail to comply with section 263.401(b).
Applicable Law
When construing a statute, an appellate court must begin with the plain language of the enactment. In re Bishop, 8 S.W.3d 412, 418 (Tex.App.-Waco 1999, no pet.). A rule of statutory construction is that every word of a statute must be presumed to have been used for a purpose. Cameron v. Terrell & Garrett, Inc., 618 S.W.2d 535, 540 (Tex.1981). If the wording of a statute is clear and unequivocal, then it is given a literal interpretation. Mathews Constr. Co. v. Jasper Hous. Constr. Co., 528 S.W.2d 323, 326 (Tex.Civ.App.-Beaumont 1975, writ ref'd n.r.e.).
Section 263.401 of the Texas Family Code requires that a court dismiss any SAPCR filed by the Department requesting *229 termination of parental rights on the first Monday after the first anniversary of the date the court rendered a temporary order appointing the Department temporary managing conservator. Tex. Fam.Code Ann. § 263.401(a). However, if the court finds that continuing the Department's conservatorship is in the child's best interest, the court may grant an extension and retain the suit on the court's docket for a period not exceeding 180 days after the one-year dismissal date. Tex. Fam.Code Ann. § 263.401(b). If the court retains the suit on its docket, the court must render an order that schedules the new dismissal date not later than the 180th day after the one-year deadline, makes additional temporary orders for the safety and welfare of the child as necessary to avoid further delay in resolving the suit, and sets a final hearing on a date that allows the court to render a final order before the required dismissal date. Id. Moreover, if the court grants an extension but does not render a final order or dismiss the suit on or before the extended dismissal date, the court must dismiss the suit. Tex. Fam.Code Ann. § 263.401(c) (Vernon 2002). Finally, the court may not grant an additional extension that extends the suit beyond the required dismissal date under section 263.401(b). Tex. Fam.Code Ann. § 263.401(c).
Section 263.401(b) previously provided that an extension order extended the court's jurisdiction of the suit. Tex. Fam.Code Ann. § 263.401(b) (Vernon Supp.2000). Recent amendments, enacted by the 77th Legislature, changed the introductory paragraph of subsection (b). Tex. Fam.Code Ann. § 263.401 historical note (Vernon 2002) [Act of May 22, 2001, 77th Leg., R.S., ch. 1090, § 8, 2001 Tex. Gen. Laws 2396]. The legislature omitted the phrase "may extend the court's jurisdiction of the suit" and substituted the phrase "may retain the suit on the court's docket for a period not to exceed 180 days." Id.; In re J.B.W., 99 S.W.3d 218, 224 (Tex.App.-Fort Worth 2003, pet. filed). The new introductory paragraph caused the dismissal deadlines, once held to be jurisdictional, to become procedural and waivable. In re J.B.W., 99 S.W.3d at 224 n. 27. Thus, the legislature removed previous limitations on the trial court's jurisdiction. Id. at 224.
Further, the Legislature amended section 263.402(b) and added a provision that requires a party to make a timely motion to dismiss the suit or to make a motion requesting the court render a final order before the dismissal deadline. Tex. Fam.Code Ann. § 263.402(b) (Vernon 2002); In re J.B.W., 99 S.W.3d at 224. Otherwise, the party waives his right to complain that the trial court failed to dismiss the suit. Tex. Fam.Code Ann. § 263.402(b); In re J.B.W., 99 S.W.3d at 224. A motion to dismiss is timely if the motion is made before the Department has introduced all its evidence, other than rebuttal evidence, at the trial on the merits. Tex. Fam.Code Ann. § 263.402(b). Moreover, these amendments applied to all SAPCRs pending on September 1, 2001. Tex. Fam.Code Ann. § 263.401 historical note (Vernon 2002) [Act of May 22, 2001, 77th Leg., R.S., ch. 1090, § 10, 2001 Tex. Gen. Laws 2398]; Tex. Fam.Code Ann. § 263.402 historical note (Vernon 2002) [Act of May 22, 2001, 77th Leg., R.S., ch. 1090, § 10, 2001 Tex. Gen. Laws 2398]. Because this suit was pending on the effective date, the new amendments are germane to our examination of the court's oral extension of the dismissal date.
If the dismissal date in section 263.401(a) passes without rendition of a final order, the court must dismiss the suit. In re Bishop, 8 S.W.3d at 419; see In re T.M., 33 S.W.3d 341, 346-47 (Tex.App.-Amarillo *230 2000, no pet.). The term "shall dismiss" without reservation imposes an obligation on the trial court to dismiss the suit. In re L.L., 65 S.W.3d 194, 196-97 (Tex.App.-Amarillo 2001, no pet.); see In re T.M., 33 S.W.3d at 346. Therefore, the court has no discretion in the matter. In re Bishop, 8 S.W.3d at 419; In re L.L., 65 S.W.3d at 197.
When a trial court officially announces its decision in open court or by written memorandum filed with the clerk, judgment is rendered. S & A Rest. Corp. v. Leal, 892 S.W.2d 855, 857 (Tex.1995); In re Ruiz, 16 S.W.3d 921, 923-24 (Tex.App.-Waco 2000, no pet.); Becker v. Becker, 997 S.W.2d 394, 395 (Tex.App.-Beaumont 1999, no pet.). "Rendition is distinguishable from the entry of judgment which is a purely ministerial act by which judgment is made of record and preserved." Becker, 997 S.W.2d at 395 (quoting Arriaga v. Cavazos, 880 S.W.2d 830, 833 (Tex.App.-San Antonio 1994, no writ)). Oral rendition of a judgment is proper. S & A Rest. Corp., 892 S.W.2d at 858 (quoting Reese v. Piperi, 534 S.W.2d 329, 330 (Tex.1976)). However, orderly administration necessitates that the rendition be in and by spoken words, not in mere cognition. Id.
In a nunc pro tunc order, a trial court has plenary power to correct a clerical error made in entering a final judgment, but cannot correct a judicial error made in rendering a judgment. Escobar v. Escobar, 711 S.W.2d 230, 231 (Tex.1986); Gutierrez v. Gutierrez, 86 S.W.3d 721, 726 (Tex.App.-El Paso 2002, no pet.). Whether an error in a judgment is judicial or clerical is a question of law. Escobar, 711 S.W.2d at 232. To determine whether a correction is a judicial or clerical error, an appellate court considers the judgment actually rendered, not the judgment that should or might have been rendered. Escobar, 711 S.W.2d at 231; National Unity Ins. Co. v. Johnson, 926 S.W.2d 818, 820 (Tex.App.-San Antonio 1996, no writ). A clerical error does not result from judicial reasoning or determination. Andrews v. Koch, 702 S.W.2d 584, 585 (Tex.1986); Gutierrez, 86 S.W.3d at 726. On the other hand, a judicial error occurs in rendering as opposed to entering a judgment. Escobar, 711 S.W.2d at 231. Further, a nunc pro tunc order may not alter or modify the terms of a judgment as rendered. Wood v. Griffin & Brand, 671 S.W.2d 125, 129 (Tex.App.-Corpus Christi 1984, no writ).
Analysis
First, Gunnels complains that the extension order of November 29, 2001 was never memorialized and filed with the court. However, the statute simply requires a court to "render" an order. Tex. Fam.Code Ann. § 263.401(b). It does not specify that the order be written. The extension of time for the dismissal deadline was announced in open court and, therefore, properly rendered according to the statute. See S & A Rest. Corp., 892 S.W.2d at 857.
Gunnels next argues that the order failed to specify a date certain for dismissal as required by section 263.401(b). Section 263.401(b) states that the order "shall" schedule a "new date." Tex. Fam.Code Ann. § 263.401(b). Use of the term "shall" imposes a duty on the trial court to follow the statute by designating a fixed date. Tex. Gov't Code Ann. § 311.016(2) (Vernon 1998); see In re Bishop, 8 S.W.3d at 418-19. Further, we are required to afford meaning to every word in a statute. In re L.L., 65 S.W.3d at 197. The Department insists that the order was proper even though it did not technically adhere to the statute and cites In re Bishop, 8 S.W.3d 412 (Tex.App.-Waco 1999, no pet.) to support its contention.
*231 The extension order in Bishop stated that the "suit shall be dismissed on dates set by amended scheduling order which date is not later than 180 days following the date this temporary order is rendered." In re Bishop, 8 S.W.3d at 418. The court found that, although the order lacked a date certain for dismissal, the extension order stipulated that the latest date the trial court could have scheduled a dismissal was 180 days after rendition of the order. Id. at 418-19. Therefore, the court found that the extension order was proper. Id. However, in this case, the extension order did not include a precise dismissal date but, instead, declared that the suit was extended for "six months." Unlike Bishop, the trial court did not specify when the six-months extension beganon the date of the extension order or on the date of the original dismissal deadline. The ambiguity of the extension order gives rise to two feasible dismissal deadlines, contrary to the plain language of the statute. Because the trial court's extension order did not comply with the mandatory, plain language of section 263.401(b), it was invalid. See In re C.V.G., 112 S.W.3d 180, 183 (Tex.App.-Houston [1st Dist.] 2003, no pet.) (concluding that because the docket notation lacked a new dismissal date the extension order was invalid).
The nunc pro tunc order set a new dismissal date of June 10, 2002 and, thus, altered the trial court's extension order. However, a nunc pro tunc order may only correct a clerical error, and may not alter or modify the terms of the order. See Riner v. Briargrove Park Prop. Owners, 976 S.W.2d 680, 682-83 (Tex.App.-Houston [1st Dist.] 1997, no pet.) (finding the nunc pro tunc judgment improper because the modifications were substantive and material, including reinstating a lien to pay for attorney's fees); Wood, 671 S.W.2d at 131-32 (finding the nunc pro tunc judgment void because alterations in the adjudicated portions of the trial court's judgment as rendered were material and constituted correction of a judicial error). Because the order in the case at hand was entered to correct a judicial error by adding a date certain for the dismissal deadline, the nunc pro tunc order was improper.
The Gunnels' motion to dismiss was timely because it was filed before the Department introduced all its evidence. See Tex. Fam.Code Ann. § 263.402(b). Because the extension order was invalid and the nunc pro tunc order was improper, Gunnels' motion to dismiss should have been granted by the trial court. Therefore, we sustain Gunnels' sole issue.

INTERVENORS' CLAIM
Gunnels contends that this case must be dismissed in its entirety because the November 29 order was invalid. Because they had standing to intervene, the Monks argue that they have rights distinct and separate from those of the Department. Further, the Monks assert that they are entitled to separate and independent relief for their cause of action. Moreover, the Monks contend that section 263.401 applies only to the Department and any actions affecting the Department in the underlying suit have no effect on their separate and independent claims.
Applicable Law
Any party may intervene in a suit by filing a pleading, subject to being stricken out by the court for sufficient cause on a motion of any party. Tex.R. Civ. P. 60; Brook v. Brook, 865 S.W.2d 166, 172 (Tex.App.-Corpus Christi 1993), aff'd, 881 S.W.2d 297 (Tex.1994). Upon filing of the petition, an intervenor becomes a party to the suit for all purposes. Brook, 865 S.W.2d at 172. If a party is nonsuited or dismissed, an opposing party's right to be heard on a pending claim for affirmative *232 relief may not be prejudiced. Pleasants v. Emmons, 871 S.W.2d 296, 298 (Tex.App.-Eastland 1994, no writ). The trial court retains jurisdiction over a pending claim for affirmative relief if the trial court initially had subject matter jurisdiction. Williams v. Nat'l Mortgage Co., 903 S.W.2d 398, 403 (Tex.App.-Dallas 1995, writ denied).
A claim for affirmative relief is a pleading that states facts showing a cause of action independent of the plaintiff's claim. Baca v. Hoover, Bax & Shearer, 823 S.W.2d 734, 737 (Tex.App.-Houston [14th Dist.] 1992, writ denied). This claim would allow the party to recover benefits, compensation, or relief despite plaintiff's abandonment or failure to establish a claim. Id.; Pleasants, 871 S.W.2d at 298. Whether a pleading is an affirmative claim for relief is determined by the facts alleged. Baca, 823 S.W.2d at 737.
Analysis
On April 17, 2002, the Monks filed an amended petition in intervention asking for termination of Gunnels' parental rights and for appointment as joint managing conservators of D.D.M. This constitutes a request for affirmative relief. See Pleasants, 871 S.W.2d at 298; Baca, 823 S.W.2d at 737. There was no motion to strike the intervention by any party. As intervenors, the Monks were parties to the suit for all purposes. See Brook, 865 S.W.2d at 172. Further, the Monks fully participated in the trial of this cause. Moreover, recent amendments to section 263.401(b) removed limitations on the trial court's jurisdiction. In re J.B.W., 99 S.W.3d at 224. Thus, because subject matter jurisdiction in the Department's suit was proper in the trial court, it retained jurisdiction over the Monks' claims for affirmative relief. See Williams, 903 S.W.2d at 403. Because their claim for affirmative relief was pending at the time of trial, the Monks' claim will not be prejudiced if the Department's suit is dismissed. See Pleasants, 871 S.W.2d at 298.

ORDER OF TERMINATION AND APPOINTMENT OF MANAGING CONSERVATOR
Even if the Department's suit is dismissed, the Monks' claim will survive because the Monks request affirmative relief independent of the Department's cause of action. See Pleasants, 871 S.W.2d at 298. Therefore, the order of termination is valid. However, if the Department's suit is dismissed, there is a question of whether the appointment of the Department as D.D.M.'s permanent managing conservator in the order of termination is also valid.
Section 161.207 of the Texas Family Code states that, if a trial court terminates a parent-child relationship, the trial court shall appoint a managing conservator of the child. Tex. Fam.Code Ann. § 161.207(a) (Vernon 2002). The managing conservator may be either a suitable, competent adult, the Department, a licensed child-placing agency, or an authorized agency. Id. Further, a trial court has the power on its own motion to award custody to any suitable person inclined to undertake this responsibility. In re Ruiz, 16 S.W.3d at 925 (quoting Bough v. Bough, 263 S.W.2d 573, 574 (Tex.Civ.App.-San Antonio 1953, no writ)). Therefore, a trial court can appoint any proper person or agency to be a managing conservator, regardless of whether such person or agency filed pleadings requesting appointment. Id.
In this case, the judge appointed the Department as permanent managing conservator. Even if the Department's suit is dismissed, the trial court has the authority to appoint any proper person or agency as D.D.M.'s managing conservator, despite a lack of pleadings requesting appointment. *233 See id. Therefore, the trial court's appointment of the Department as D.D.M.'s permanent managing conservator is valid.

CONCLUSION
Based upon our review of the record, we conclude that the trial court erred in denying Gunnels' motion to dismiss because the court's oral order did not meet the statutory requirements for an extension of the one-year dismissal deadline. Accordingly, the order of the trial court denying Gunnels' motion to dismiss is reversed, and this cause is remanded with instructions to dismiss the Department's cause of action without prejudice in accordance with section 263.401 of the Texas Family Code. However, we also conclude that the Monks' petition for termination and conservatorship survives the dismissal of the Department's cause of action and that the Department can be appointed permanent managing conservator in the absence of pleadings requesting the appointment. Therefore, the order of termination, including the appointment of the Department as permanent managing conservator of D.D.M., is affirmed.
NOTES
[1]  Unless a court renders a final order or grants an extension, on the first Monday after the first anniversary of the date that the Department was appointed temporary managing conservator, a court must dismiss a SAPCR filed by the Department requesting termination of the parent-child relationship. Tex. Fam.Code Ann. § 263.401(a) (Vernon 2002). The one-year dismissal deadline in this suit was Monday, December 10, 2001.
[2]  All statutory references are to the Texas Family Code unless otherwise indicated.
[3]  A proper extension order must schedule the new date for dismissal of the suit not later than the 180th day after the dismissal deadline, make further temporary orders for the safety and welfare of the child as necessary to avoid further delay in resolving the suit, and set a final hearing on a date that allows the court to render a final order before the new dismissal date of the suit. Tex. Fam.Code Ann. § 263.401(b) (Vernon 2002).
