This guide covers divorce filing, custody arrangements, and family law specific to Montana (MT). Laws, programs, and resources vary by state, and this page focuses on what Montana residents need to know.
Divorce Filing Requirements
Montana has specific residency requirements before you can file for divorce. You must meet these requirements before the court will accept your petition.
Montana recognizes both fault and no-fault grounds for divorce. The most common ground used is irreconcilable differences or irretrievable breakdown of the marriage.
Property Division
Montana follows equitable distribution rules for dividing marital assets. This means the court divides property fairly, which does not always mean equally.
Separate property -- assets owned before marriage, gifts, and inheritances -- is generally not divided. However, commingling separate property with marital funds can change its classification under Montana law.
Child Custody
Montana courts make custody decisions based on the best interests of the child. Factors include each parent's relationship with the child, stability of the home environment, and the child's own preferences if old enough.
Montana recognizes both legal custody (decision-making authority) and physical custody (where the child lives). Joint custody arrangements are common but not automatic.
Spousal Support
Alimony in Montana is not guaranteed. Courts consider factors including the length of the marriage, each spouse's earning capacity, age, health, and the standard of living established during the marriage.
Montana may award temporary support during the divorce process, rehabilitative support to help a spouse become self-sufficient, or long-term support in cases of lengthy marriages.
