How Alimony Is Determined

Unlike child support, most states do NOT have a strict formula for alimony. Judges consider: income disparity (the core factor), marriage length (longer = more/longer alimony), standard of living during marriage, earning capacity of each spouse, age and health, and contributions (including homemaking and supporting the other career). A common guideline: 30-35% of the income difference for a duration equal to 50-70% of the marriage length.

Types of Alimony

Temporary: During divorce proceedings. Rehabilitative: Time-limited to allow the lower earner to gain skills/education. Permanent: Ongoing, typically for marriages of 20+ years where one spouse sacrificed career. Lump-sum: One-time payment instead of ongoing. Most modern alimony is rehabilitative (time-limited), not permanent.

Frequently asked questions
How long does alimony last?
General guidelines: short marriages (under 5 years) get 1-3 years. Medium marriages (5-15 years) get 3-7 years. Long marriages (15-20+ years) may get half the marriage length or permanent alimony. These vary significantly by state and judge.
Can alimony be changed?
Usually yes — through modification if circumstances change substantially (job loss, retirement, recipient remarriage or cohabitation). Many states automatically terminate alimony upon the recipient remarriage. Some agreements are non-modifiable — check your divorce decree.
