Types of Alimony in Alaska
Alaska courts may award the following types of alimony:
- Temporary (pendente lite support during divorce proceedings)
- Rehabilitative (funds education or job training to become self-supporting
- typically up to 4 years)
- Reorientation (helps lower-earning spouse adjust to reduced standard of living
- typically 1 year or less)
- Permanent (ongoing support
- rare
- reserved for long-term marriages where spouse cannot become self-supporting)
How Alaska Calculates Alimony
Alaska does not have a fixed formula for calculating alimony. Courts use judicial discretion, weighing multiple factors to determine a fair amount and duration.
Alaska courts consider these factors when determining alimony:
- Under AS 25.24.160(a)(2)
- courts must consider: (A) length of the marriage and station in life of the parties during the marriage; (B) age and health of the parties; (C) earning capacity of each party
- including educational background
- training
- employment skills
- work experience
- length of absence from the job market
- and custodial responsibilities for children during the marriage; (D) financial condition of the parties
- including the availability and cost of health insurance; (E) conduct of the parties
- including whether there has been unreasonable depletion or destruction of marital assets; (F) the division of property made under the divorce judgment; (G) any other factor the court determines to be relevant in the particular case
Income disparity: YES — the fundamental purpose of Alaska spousal support is to “fairly allocate the economic effect of divorce,” which requires demonstrating that the divorce creates an economic disparity or financial need for the requesting spouse
Vocational evaluation: Alaska courts may use vocational evaluations to assess a spouse’s earning capacity, but they are not specifically mandated by statute. Courts consider earning capacity as a statutory factor under AS 25.24.160(a)(2), and vocational experts may be retained to evaluate education, skills, work history, and potential earning ability.
Alaska Alimony Duration Guidelines
No statutory duration guidelines or caps tied to length of marriage. Judges have broad discretion to set duration based on case-specific factors. Temporary support typically lasts 6-12 months (during proceedings). Rehabilitative support commonly lasts up to 4 years. Reorientation support is usually limited to 1 year or less. Permanent support has no end date but is rare.
| Marriage Length | Typical Alimony Duration |
|---|---|
| Short-term (under UNVERIFIED — Alaska statute does not define a specific short-marriage threshold in years) | Rehabilitative or bridge-the-gap; limited duration |
| Moderate-term | Durational alimony; set period based on marriage length |
| Long-term (UNVERIFIED — Alaska statute does not define a specific long-marriage threshold in years; case law generally reserves permanent support for marriages of substantial duration where a spouse cannot become self-supporting+) | May qualify for permanent or indefinite alimony |
Permanent alimony: YES — permanent alimony is available but rare in Alaska; generally reserved for long-term marriages where the receiving spouse cannot become self-supporting due to age, health, or other circumstances
Modifying & Terminating Alaska Alimony
Modification: YES — under AS 25.24.170, spousal support orders may be set aside, altered, or modified when a party demonstrates a substantial and ongoing material change in circumstances. Common grounds include significant income changes, job loss, disability, or retirement. Modification may be barred if the parties agreed in writing that neither will seek modification.

Cohabitation: Cohabitation does NOT automatically terminate spousal support in Alaska. However, the paying spouse may file a Motion to Modify under AS 25.24.170, arguing the new living arrangement represents a material change in circumstances that reduces the recipient’s financial need. Courts evaluate factors including shared expenses, duration of the cohabitation, and whether the relationship resembles a marriage in function.
Remarriage: Remarriage of the receiving spouse automatically terminates spousal support in Alaska. The Alaska Supreme Court ruled in Voyles v. Voyles (1982) that remarriage serves as an election between the alimony award and the support obligation of the new marriage. The paying spouse’s obligation ends immediately upon remarriage without requiring a court motion or modification order.
Retirement: Retirement of the payor can constitute grounds for modification of spousal support as a substantial change in circumstances under AS 25.24.170. Good-faith retirement at or after standard retirement age is generally recognized as a legitimate basis to petition for reduction or termination. Courts examine the specific circumstances of the retirement.
Tax Implications of Alaska Alimony
Under the Tax Cuts and Jobs Act (2017), for divorce agreements executed after December 31, 2018, alimony payments are not deductible by the paying spouse and not taxable income for the receiving spouse at the federal level. This applies to all Alaska divorces finalized after that date.
For divorces finalized before 2019, the old rules still apply unless the agreement is modified to adopt the new tax treatment.
Impact of Misconduct on Alaska Alimony
Adultery: Adultery does NOT directly affect spousal support awards in Alaska. Alaska’s alimony law does not allow judges to consider marital fault when determining alimony. However, if an adulterous spouse unreasonably spent marital funds on an affair partner, that economic misconduct may be considered under the “conduct of the parties” factor regarding depletion of marital assets.
Other marital misconduct: General marital misconduct (other than economic misconduct) does NOT affect spousal support in Alaska. Alaska takes a financially-focused approach, excluding traditional marital fault considerations. Only economic misconduct — such as unreasonable depletion, dissipation, or destruction of marital assets — may be considered under AS 25.24.160(a)(2)(E).
Additional Alaska rules: Alaska recognizes a unique type of spousal support called “reorientation support” (distinct from rehabilitative), designed to help a spouse adjust to a reduced standard of living, typically limited to 1 year or less. Alaska has no state income tax, which simplifies tax treatment of support payments. Alaska is an equitable distribution state. The court has discretion to consider “any other factor” it deems relevant, giving judges unusually broad latitude. There are no statutory caps on amount or duration of any type of spousal support.
