¶ 1 The parties were divorced in Tulsa County, Oklahoma in 1998 and Wife received custody of the children. In her Motion to Modify Child Support, filed September 27, 2002, Wife stated that Husband had a back injury at the time of divorce and that for the purpose of child support computation, the trial court attributed $4000 per month to him for a monthly wage. As the basis for her Motion to Modify Child Support, Wife claimed that Husband had received a large settlement for his back injury. At the time of the filing of the Motion to Modify in Tulsa County, Wife and children were living in Colorado and Husband was living in California. Husband’s motion to dismiss, on the ground that Oklahoma had lost jurisdiction to modify the order pursuant to the Oklahoma Uniform Interstate Family Support Act, 43 O.S.2001 § 601-100 et seq., was granted. We affirm.
¶ 2 Title 43 O.S.2001 § 601-205A states:
A tribunal of this state issuing a support order consistent with the law of this state has continuing, exclusive jurisdiction over a child support order:
1. As long as this state remains the residence of the obligor, the individual obli-gee, or the child for whose benefit the support order is issued; or
2. Until all of the parties who are individuals have filed written consents with the tribunal of this state for a tribunal of another state to modify the order and assume continuing, exclusive jurisdiction.
*579 ¶ 3 As stated, when Wife moved to modify the child support order in the District Court of Tulsa County, the court which had issued the initial child support order, neither she, the children, nor Husband were residents of Oklahoma. The record also reveals that none of the parties had filed written consents in the District Court of Tulsa County for a tribunal of another state to assume jurisdiction for modification of the child support order.
¶ 4 The standard and scope of review as to whether a court has subject matter jurisdiction is reviewáble
de
novo.
Garrison v. Bechtel Corp.,
¶ 5 In
Etter v. Etter,
¶ 6 In the case at hand, Oklahoma lost subject matter jurisdiction to modify the child support order as soon as Husband (obli-gor), Wife (obligee), and children (those for whose benefit the support order issued) no longer resided in this state. Local residence of at least one of that triad is necessary to establish the nexus for UIFSA subject matter jurisdiction.
¶ 7 Appellant also argues that Appel-lee consented to the jurisdiction of the court. Parties may not confer subject matter jurisdiction by consent.
Barrett v. Barrett,
¶ 8 Appellant’s Motion to Submit Appellate Briefs is denied.
¶ 9 The District Court of Tulsa County, Oklahoma, lacked subject matter jurisdiction over Wife’s Motion to Modify Child Support. The order dismissing the motion is AFFIRMED.
Notes
. Wife argued in her trial brief that Husband had personally submitted to the jurisdiction of the District Court of Tulsa County. Although Husband denied this, it was irrelevant anyway. Parties cannot imbue a court with subject matter jurisdiction.
. The issuing tribunal only loses subject matter jurisdiction when all the parties no longer reside within its boundaries. It may still enforce the child support order if it has not been modified.
