Idaho Alimony & Spousal Support (2026)
Unlike child support, Idaho has no fixed formula for how much alimony (spousal support) costs or how long it lasts. A judge decides both based on a list of factors set out in Idaho Code § 32-705. There is no calculator that can honestly give you an exact number here — but the factors below are what actually drives the decision.
What determines alimony in Idaho
Under Idaho Code § 32-705 (Idaho Code § 32-705 (Maintenance)), a court considers:
- The financial resources of the spouse seeking maintenance, including marital property apportioned to them, and their ability to meet their needs independently
- Time necessary to acquire sufficient education or training to find employment
- Duration of the marriage
- Age and the physical and emotional condition of the spouse seeking maintenance
- The other spouse's ability to meet their own needs while paying maintenance
- Tax consequences to each spouse
- Fault of either party
Good to know
- Idaho has no statutory formula for the amount or duration of spousal maintenance — Idaho Code § 32-705 lists factors for the court to weigh 'in such amounts and for such periods of time that the court deems just.'
- Idaho is a no-fault divorce state, but § 32-705 explicitly allows the court to consider marital fault as one factor in setting maintenance.
