OPINION
Near the end of his temporary spousal maintenance obligation, the trial court ordered John Vincent Martine, Sr., to continue maintenance payments for one year. On appeal, Martine argues: (1) the parties’ judgment and decree divested the trial court of jurisdiction to modify spousal maintenance; and (2) the trial court abused its discretion in extending rehabilitative maintenance at its current level for one year.
FACTS
Lucila Nicole Santillan and John Vincent Martine, Sr., married in 1980 and divorced in 1994. The trial court awarded the parties joint legal and physical custody of their three minor children. At the time of dissolution, Santillan was a full-time student at the University of Minnesota, working toward a Bachelor of Arts in political science, which she expected to receive in June 1995. Santil-lan was not gainfully employed while in school. Due to Santillan’s economic dependence on Martine, who was employed full-time, the parties stipulated to temporary maintenance of $700 per month for a period of 20 months. They further stipulated: “The Court shall be divested of jurisdiction to modify the spousal maintenance provision.” The trial court incorporated verbatim these stipulations into the judgment and decree.
On December 29, 1995, two days before the expiration of Martine’s maintenance obligation, Santillan served him with a motion to modify child support and visitation and to extend temporary maintenance. At the time of that motion, Santillan was employed part-time selling Herbalife products and doing clerical work. She had failed to complete her college degree, due, she claimed, to her increased childcare duties as a result of problems in Martine’s home. After a hearing before a referee, the trial court: (1) concluded it had jurisdiction because Santillan had served her motion prior to the date of divestiture of jurisdiction under the judgment and decree; and (2) ordered a one-year extension of Martine’s temporary maintenance obligation on the basis of Santillan’s inability to complete her schooling.
ISSUES
I. Did the trial court err in exercising jurisdiction over Santillan’s motion to modify spousal maintenance?
II. If not, did the trial court abuse its discretion in extending rehabilitative maintenance at its current amount for one year?
ANALYSIS
A trial court has broad discretion over issues of spousal maintenance, and this court will not reverse a trial court’s decision absent an abuse of that discretion.
Rutten v. Rutten,
I.
Prior to the enactment of Minn.Stat. § 518.552, subd. 5, stipulated divestitures of trial court jurisdiction over spousal maintenance modifications were governed by the supreme court’s decision in
Karon,
which gave effect to such stipulations when incorporated by a trial court into a judgment and decree.
Karon v. Karon,
The parties may expressly preclude or limit modification of maintenance through a stipulation, if the court makes specific findings that the stipulation is fair and equitable, is supported by consideration *751 described in the findings, and that full disclosure of each party’s financial circumstances has occurred.
Minn.Stat. § 518.552, subd. 5 (1996);
see Loo v. Loo,
Martine argues the trial court erred in exercising jurisdiction over Santillan’s motion to modify spousal maintenance because the parties’ judgment and decree contains express divestiture language. However, a stipulated divestiture of jurisdiction is effective only if the trial court, in adopting the stipulation, makes specific written findings that the stipulation is fair and equitable and supported by specified consideration, and that both parties have made full financial disclosures. Minn.Stat. § 518.552, subd. 5;
see
Minn.Stat. § 645.08(1) (1996) (requiring statutory interpretation according to common and approved usage of words);
Bennett Comm’n Co. v. Northern Pac. Ry.,
Santillan’s and Martine’s judgment and decree, which incorporated the parties’ stipulation in its entirety, did not include the specific findings required by Minn.Stat. § 518.552, subd. 5. Under these circumstances, we must conclude the judgment failed to divest the trial court of subject matter jurisdiction over modifications of spousal maintenance. 1
II.
A party seeking modification of a spousal maintenance award must demonstrate a substantial change in circumstances that renders the existing award unreasonable and unfair. Minn.Stat. § 518.64, subd. 2(a) (1996);
Wiese v. Wiese,
The trial court extended Martine’s maintenance obligation for one year because Santillan had not completed her college degree as the parties had contemplated at the time of the judgment and decree.
See Katter v. Katter,
DECISION
Under the express language of Minn.Stat. § 518.552, subd. 5, the divestiture clause in the dissolution judgment and decree failed to divest the trial court of jurisdiction to address Santillan’s motion to modify spousal maintenance. Although the trial court properly exercised jurisdiction, we must reverse and remand for findings sufficient to support the court’s extension of temporary spousal maintenance.
Affirmed in part, reversed in part, and remanded.
Notes
. In finding jurisdiction to exist, the trial court concluded the stipulation's provision that the court "shall be divested of jurisdiction” was not to take effect until the termination date of Mar-tine’s original maintenance obligation.
