Montana Divorce Self-Help Tools

Montana has a mandatory 21-day waiting period after filing. Uncontested divorces typically finalize in 60–120 days for uncontested cases. Contested divorces involving custody disputes or complex assets can take 12–24 months or longer.

To file for divorce in Montana, there is no fixed residency waiting period, though you must be domiciled in Montana at the time of filing. Filing in the wrong jurisdiction can result in your case being dismissed, so confirm with your county clerk if you recently moved.

Montana is a no-fault divorce state. You can file citing 'irreconcilable differences' or 'irretrievable breakdown of the marriage' without proving the other spouse did anything wrong. Fault grounds (adultery, cruelty, abandonment) still exist but are rarely needed and don't typically affect property division.

Montana follows equitable distribution. Courts divide marital property fairly but not necessarily equally, considering factors like each spouse's income, contributions to the marriage, and economic circumstances. Separate property (owned before marriage or received as a gift or inheritance) is generally not divided.

Montana uses the Hybrid model to calculate child support. Both parents' incomes are considered along with the number of children, timesharing schedule, childcare costs, and health insurance. The resulting guideline amount is presumed correct but a judge can deviate based on special circumstances.
