OPINION
STATON, Judge.Michael Kizziah appeals the denial of his motion to modify a dissolution decree which he entered into with his former wife Angie Kizziah. Michael raises one issue on appeal and Angie raises one issue on cross appeal; we restate these issues as follows:
I. Whether the trial court erred in determining that the parties' agreed maintenance provision was non-modifiable.
II. Whether the trial court erred in its calculation of maintenance arrearage.
We reverse and remand.
The facts most favorable to the judgment are as follows. Michael and Angie entered into a property settlement agreement ("Agreement") which provided for the division of marital assets, custody, child support, visitation, and alimony. The trial court approved the Agreement and incorporated it into a dissolution decree.
Michael agreed to pay Angie $606 monthly for alimony. The Agreement stated that this amount is "fixed until [Angie] remarries at which time [Michael's] obligation for payment of this support to [Angie] denominated as alimony will cease." Record, p. 45. Michael sought to modify the dissolution decree based upon a change in employment which he alleged makes the Agreement unreasonable. The trial court denied the petition holding the language of the Agreement precludes modification; Michael appeals.
I.
Maintenance Modification
Michael argues that the trial court erred in holding that the monthly payments are not subject to judicial modification. He claims the Agreement is ambiguous on this point.
We first determine the nature of the monthly payments. The Agreement's denomination of the payments as "alimony"1 does not determine their true nature. DeVoe v. DeVoe (1988), Ind.App., 581 N.E.2d 1200, 1202. As a matter of law, payments which terminate upon a change of cireumstances, in this case marriage, cannot constitute a division of marital property. Id. Further, spousal support payments which are not a division of marital property are maintenance. Id. Michael and Angie agree the monthly payments are maintenance.
We next examine the Agreement. Indiana expressly encourages divorcing couples to reach agreements settling their affairs. IC. § 31-1-11.5-10(a). Dissolution decrees entered into by agreement of the parties implicate contract principles. Bowman v. Bowman (1991), Ind.App., 567 N.E.2d 828, 831. This gives parties more flexibility in crafting dissolution decrees, and they may agree to provisions which a trial court could not order; e.g., non-modifiable maintenance payments. Id.
Acknowledging this, Michael argues that the language of the Agreement does not prohibit judicial modification. The parties' intent, as determined by the clear *299language of the contract, controls when interpreting an agreement. In Re Marriage of Loeb (1993), Ind.App., 614 N.E.2d 954, 957. If the contract language is unambiguous, construction of the agreement is a question of law for the court. Id.
In Bowman, this court held the following language sufficient to preclude judicial modification: "it being understood that [the maintenance] obligation shall not in any way be modified." Bowman, supra, at 829. This language clearly and unmistakably seeks to insulate the payments from judicial modification.
The language used in this Agreement, however, is less clear. The Agreement states that the maintenance "amount is fixed until the wife remarries." Record, p. 45. To say an amount is fixed is less clear regarding modification than to say the amount cannot be modified. "Fixed" might mean no more than the amount is unaffected by minor flue-tuations in the payor spouse's income or payee spouse's need. The term does not unmistakably foreclose judicial modification.
Recently, this court held a maintenance agreement modifiable despite a general non-modification clause covering the agreement as a whole. Voigt v. Voigt (1994), Ind.App., 645 N.E.2d 627, trans. pending. The Voigt court held that the general clause did not "specifically and unambiguously preclude modification of maintenance provisions" as did the Bowman agreement. Id, at 680. We conclude that the language of this Agreement is more similar to the equivocal language of Voigt than the unmistakable language of Bowman.
Further, - Indiana - disfavors - indefinite spousal maintenance payments. This is evidenced by the statutory prerequisite allowing a court to order maintenance only if the payee spouse is incapacitated, cannot support an incapacitated child, or needs job training for a brief time. IC. § 31-1-11.5-11(e). Even under these cireumstances, maintenance is not mandatory, Rump v. Rump (1988), Ind.App., 526 N.E.2d 1045, 1046, trans. denied, and is subject to judicial modification, Bowman, supra. In addition, public policy disfavors indefinitely locking parties into sum-certain maintenance payments regardless of possible misfortune which might befall the payor spouse and windfalls which might grace the payee spouse.
For these reasons, language foreclosing judicial modification of maintenance payments must be specific and unmistakable. This is not a novel principle of contract law. We routinely require specific, unmistakable language for other disfavored contract provisions.2 This requirement is sound because litigants should not find themselves indefinitely locked into maintenance payments unless they clearly bargained for that arrangement.
We conclude that the Agreement does not specifically and unambiguously preclude judicial modification of maintenance payments. While non-modification language need not be identical to that in Bowman, it must unmistakably indicate an intent to insulate maintenance from judicial modification. On remand, Michael can present evidence in an attempt to demonstrate a substantial and continuing change of circumstance which makes the Agreement unreasonable.
II.
Calculation of Arrearage
On cross-appeal, Angie argues that the trial court erred in calculating maintenance arrearage.3 The Agreement required *300Michael to make payments on the first day of each month, beginning with the month after the parties sold the marital home.
The marital home was sold on April 30, 1992 and Michael, properly, made the first maintenance payment on May 1, 1992. Michael made the June and July payment, but none thereafter, putting him thirteen months in arrears at the time of the August 18, 19983 judgment.
The trial court fixed the maintenance ar-rearage at $7,272 (twelve months at $606 per month). However, as stated, Michael had missed thirteen payments, not twelve. Therefore, the total arrearage was $7,878 at that time. Michael does not dispute these calculations. We direct the trial court to modify the arrearage accordingly.
Reversed and remanded to the trial court for proceedings consistent with this opinion.
SULLIVAN, J., concurs and files separate concurring opinion. HOFFMAN, J., concurs in part and dissents in part and files separate opinion.. We note that alimony, under that name, is no longer recognized in Indiana. LC. § 31-1-11.5~-11; Hicks v. Fielman (1981), Ind.App., 421 N.E.2d 716, 722.

. Angie also argues that the trial court should have awarded her half the realtor commission reimbursement from the sale of the marital home. The trial court did not rule on this issue in its order or in its ruling on Michael's motion to correct error; so Angie cannot appeal it at this time. Strutz v. McNagny (1990), Ind.App., 558 N.E.2d 1103, 1109, trans. denied.
