Estimate maintenance under AS 25.24.160: shortfall, ability to pay and the seven statutory factors

Alaska has no alimony formula. Under AS 25.24.160(a)(2), a court may award maintenance for a limited or indefinite period of time, in gross or in installments, as may be just and necessary, without regard to which of the parties is in fault.

The award must fairly allocate the economic effect of divorce and be based on seven factors: (A) the length of the marriage and station in life of the parties during the marriage; (B) the age and health of the parties; (C) the earning capacity of the parties, including education, training, employment skills, work experience, length of absence from the job market, and custodial responsibilities for children during the marriage; (D) the financial condition of the parties, including the availability and cost of health insurance; (E) the conduct of the parties, including whether there has been unreasonable depletion of marital assets; (F) the division of property; and (G) other factors the court finds relevant.

The statute describes maintenance by timing and form: it may be for a limited or indefinite period, and paid in gross (a lump sum) or in installments. It sets no maximum duration and no list of support types.

In practice, awards are often described as temporary (while the case is pending, under AS 25.24.140), rehabilitative (to cover education or training), reorientation (a short transition), or long-term. Those are descriptive labels, not statutory categories with fixed limits, and the judge decides the length.

Marital fault as such does not. Maintenance is awarded without regard to which of the parties is in fault (AS 25.24.160(a)(2)). However, the conduct of the parties is a listed factor, including whether there has been unreasonable depletion of marital assets (§ 25.24.160(a)(2)(E)).

The division of property is itself one of the maintenance factors (§ 25.24.160(a)(2)(F)), and the property division must also fairly allocate the economic effect of divorce (§ 25.24.160(a)(4)). Property acquired during the marriage is divided in a just manner, and the court may invade property acquired before the marriage when the balancing of the equities requires it. Because the two interact, maintenance and property are considered together.

Yes, by court order. Under AS 25.24.170(a), any time after judgment the court, on the motion of either party, may set aside, alter, or modify the part of the judgment that provides for alimony or for the maintenance of either party. Courts generally require a material change in circumstances before modifying support.

The statute does not list events that end support automatically. Whether payments end on remarriage, cohabitation, retirement or death depends on the terms of the decree or settlement and on Alaska case law, so do not assume support has stopped. Stop paying only after a court order or a properly approved written agreement.

Alaska's maintenance statute has no percentage adjustment for domestic violence, and marital fault is not a stand-alone factor. But in Kilkenny v. Kilkenny, No. S-18602 (Alaska Sept. 19, 2025), the Alaska Supreme Court held that a superior court could decline to enforce parts of a prenuptial agreement, including terms barring spousal support, attorney's fees and an unequal division of the marital estate, because changed circumstances (the husband's domestic violence) made enforcement unfair, even though the agreement was voluntarily signed and not unconscionable.

Alaska courts generally enforce premarital agreements that were voluntarily made and are not unconscionable, but review them under a changed-circumstances rule (see Brooks v. Brooks, 733 P.2d 1044 (Alaska 1987)). Ask an attorney how that applies to your agreement.

For divorce or separation agreements executed after December 31, 2018, alimony is not deductible by the payor and is not taxable income to the recipient for federal income tax purposes, under the Tax Cuts and Jobs Act of 2017. That federal change has no scheduled expiration.

Agreements executed on or before December 31, 2018 keep the old treatment (deductible for the payor, taxable to the recipient) unless a later modification expressly states that the new rules apply. Alaska has no state individual income tax, but consult a tax professional about your situation.

The PFD is money a spouse receives each year, so it can be part of a spouse's financial condition (AS 25.24.160(a)(2)(D)). The calculator asks for monthly income. If you want to include the dividend, add one-twelfth of the annual amount to that spouse's income.

The dividend amount changes from year to year, and a court decides how to treat it, so treat any figure as an estimate.

Because Alaska has no formula, the calculator uses a transparent illustration tied to the statute's concepts: the recipient's monthly shortfall (monthly needs minus the recipient's income) compared with the money the payor has available (take-home income minus the payor's expenses and child support). The illustrative amount is the smaller of the two.

It does not predict what a judge will order. It does not model the property division or the court's weighing of the factors. Your results list how your answers line up with each statutory factor, (A) through (G), for discussion with an attorney. Alaska's regional cost differences are reflected in the actual expenses you enter, not in a regional multiplier.
