OPINION
¶ 1 Aрpellant Romeo Cabrera challenges the trial court’s order modifying the portion of the parties’ marital dissolution decree relating to the physical custody of his and appellee Victoria Cabrera’s son. Romeo contends the trial сourt erred in allowing Victoria to deviate from the prehearing change of custody procedures in A.R.S. § 25-411, in deviating from those procedures itself, and in granting visitation to Victoria’s current husband, appellee Theodore Dorman. Because only our resolutiоn of the issue concerning § 25-411 merits publication, we address the visitation issues in a separate memorandum decision. Ariz. R. Civ.App. P. 28(g), 17B A.R.S. We affirm.
BACKGROUND
¶ 2 The relevant facts are not in dispute. Romeo and Victoria’s 1996 dissolution decree provided joint legal and physical сustody of their son, with each parent having substantially equal time with the child. In March 1999, Victoria filed a verified petition requesting the court order that the child reside with Romeo because she was being deported to the Philippines and anticipated remaining thеre for six months to a year while her application for permanent resident status was processed. Her petition also asked that the court award her current husband visitation every other weekend and that she be awarded visitation in the Philippines undеr certain circumstances. Romeo objected and, after a two-day hearing, the trial court, in effect, granted Romeo primary physical custody of the child and Victoria and/or her current husband visitation on alternate weekends and in the Philippines during the summer and winter of 1999. This appeal followed. 1
APPELLATE JURISDICTION
¶ 3 Preliminarily, Victoria challenges our jurisdiction to consider this appeal, arguing that the order from which Romeo appeals is a temporary, rather than a final, order. We have jurisdiction to review special orders made after judgment. A.R.S. §§ 12-120.21(A)(1) and 12-2101(0). To be appealable, a special order after judgment must raise different issues than those that would be raised by appealing the underlying judgment; it must affect the underlying judgment, relate to its enforcement, or stay its execution; and it must not be “merely ‘preparatory’ to a later proceeding that might affect the judgment or its enforcement.”
Arvizu v. Fernandez,
¶ 4 The order at issue here, which grants Romeo primary physical custody of the child, raises different issues than those that would
*301
have arisеn from the underlying dissolution decree and affects the underlying decree and its enforcement. And the order is not “merely preparatory”; it resolves all the issues raised in the petition for an order to show cause and, although it is modifiable,
see
A.R.S. § 25-403, it can continue until the child reaches majority. The order is, therefore, an appealable special order after judgment. § 12-2101(C);
see Cone v. Righetti,
DISCUSSION
¶5 We first address Victoria’s claim that § 25-411 does not apply to this case. The statute provides:
A party seeking a modification of any type of custody order shall submit an affidavit or verified petition setting forth detailed facts supporting the requested modificаtion and shall give notice, together with a copy of his affidavit, or verified petition to other parties to the proceeding, who may file opposing affidavits. The court shall deny the motion unless it finds that adequate cause for hearing the motion is estаblished by the pleadings, in which case it shall set a date for hearing on why the requested modification should not be granted.
Victoria contends § 25-411 does not apply here because she did not request that the court modify the prior custody order but, rather, that it modify “thе child access schedule.” We disagree. Victoria’s request that the court change the parties’ access to the child from substantially equal time to a situation in which the child resides with Romeo and has minimal visitation with Victoria or her current husband is a modificаtion of the physical custody order and is subject to § 25-411.
See DePasquale v. Superior Court,
¶6 We next consider Romeо’s argument that the trial court did not have jurisdiction to issue the order modifying the prior custody order because Victoria failed to initiate proceedings under § 25-411, and the trial court failed to determine, as required by § 25-411, whether Victoria had demonstrated adequate cause for modification before ordering a hearing. We review de novo whether the trial court had jurisdiction to issue its order.
See In re Marriage of Crawford,
¶7 Subject matter jurisdiction is “ ‘the power to hear and determine cases of the general class to which the particulаr proceedings belong. . . . . ’ ”
Estes v. Superior Court,
¶ 8 In determining whether § 25-411 is jurisdictional, we attempt to ascertain and give effect to the legislature’s intеnt.
Hale v. Amphitheater Sch. Dist. No. 10,
¶ 9 The language of § 254111 does not indicate an intent to limit the jurisdiction granted by the constitution or the jurisdictional statutes. And § 25-411 was derived from § 410 of the Uniform Marriage and Divorce Act (amended 1973), 9A Pt. II U.L.A. 538 (1998) (hereinafter UMDA). The commentary to that section cleаrly indicates the section is procedural. It states that
[t]his section establishes a procedure for seeking temporary custody or a modification of a custody decree by motion supported with affidavits. The procedure is designed to result in denial of the motion without a hearing unless the court finds that the affidavits establish adequate cause for holding a hearing. The procedure will thus tend to discourage contests over temporary custody and prevent repeated or insubstantial motions for modification.
UMDA § 410 cmt., 9A Pt. II U.L.A. 539. (Emphasis added.) Were we to conclude otherwise, it would permit а parent displeased with a post-hearing custody modification to challenge that decision based on a defect in the preliminary prehearing procedures. “The administration of justice, already under great weight, needs no further burden.”
Taliaferro v. Taliaferro,
¶ 10 Because the requirements of § 25-411 are procedural and not jurisdiсtional, errors in interpreting or complying with them may be reversible error, but do not affect jurisdiction.
While misconstruing a jurisdictional law is fatal to the viability of a court’s decision, misinterpreting a procedural law does not void a court’s decision. The court still rеtains jurisdiction over that class of case. Misinterpreting a procedural matter amounts to legal error which may result in reversal by an appellate court, but subject matter jurisdiction remains unaffected by the misinterpretation.
Estes,
¶ 11 Romeo claims that Victoria and the trial court failed to comply with § 25-411, and that the failures constitute reversible error. However, we decline to consider the merits of this claim for two reasons. First, § 25-411 is a prehearing procedural statute and its purpose is, in part, to “prevent repeated or insubstantial motions for modification.” UMDA § 410 cmt., 9A Pt. II U.L.A. 539;
see Pridgeon v. Superior Court,
¶ 12 Second, we will not reverse for alleged noncompliance with § 25-411 on appeal absent a showing of prejudice.
See
Ariz. Const. art. VI, § 27 (“No cause shall be reversed for technical error in pleadings or proceedings whеn upon the whole case it shall appear that substantial justice has been done.”);
see also Vasho,
1113 Here, although Romeo alleges the procedural violations deprived him “of his opportunity for discovery and a full hearing,” nоncompliance with the prehearing verification and screening procedures was not the cause of any of the alleged deprivations. And he has not shown what additional discovery he would have conducted, what additional evidence he wоuld have presented, or how it would have affected the trial court’s decision. Moreover, Romeo’s argument below regarding discovery related to the best interest of the child, a finding he does not challenge on appeal.
Cf Michael J. v. Arizona Dep’t of Econ. Sec.,
¶ 14 Accordingly, we do not address the merits of Romeo’s claim that Victoria and the trial court failed to comply with § 25-411 because he failed to challenge the alleged noncompliance by special action and he failed to demonstrate any prejudice from the trial court’s procedures.
CONCLUSION
¶ 15 The trial court’s order is affirmed. 3 Both parties’ requests for an award of fees and costs on appeal pursuant to Rule 25, Ariz. R. Civ.App. P., 17B A.R.S., are denied.
Notes
. Romeo's and Victoria’s briefs fail to comply with Rule 13(a) and (b), Ariz. R. Civ.App. P., 17B A.R.S., because their factual recitations do not contain proper citations to the record. Although we'have considered this appeal rather than striking the briefs, counsel are cautioned that such noncompliance may result in sanctions in the future.
