Uncontested divorces in Montana typically finalize 30–60 days after filing. Contested cases generally take 9–18 months. Montana has no mandatory waiting period beyond procedural requirements.

Yes — Montana is a pure no-fault state. The only ground for dissolution is irretrievable breakdown of the marriage under Mont. Code § 40-4-104. Fault is not considered.

No mandatory pre-filing separation, though the court must find that the parties have lived separate and apart for more than 180 days OR that serious marital discord adversely affects one or both parties — usually established by affidavit.

Montana is an equitable distribution state with a broad reach — under Mont. Code § 40-4-202, the court can equitably apportion ALL property, including premarital property if equity requires. The court considers 13 factors including age, health, occupation, vocational skills, employability, estate, liabilities, conduct, and contributions.

Montana uses parenting plans under Mont. Code § 40-4-212. Courts consider 11 best-interests factors including the child’s wishes, parents’ wishes, child’s interactions, child’s adjustment, mental/physical health, abuse, chemical dependency, continuity, and developmental needs. Montana has no preference for any custodial arrangement.

Montana uses the Melson Formula under the Montana Child Support Guidelines — three steps: (1) each parent’s self-support reserve, (2) primary child support need, and (3) standard-of-living allowance. More complex than Income Shares but designed to ensure both minimum self-support and children’s standard of living.

Yes. Parenting plans can be amended on a change in circumstances. Child support requires a substantial and continuing change. Maintenance modification depends on the decree. Property division is final.
