The estate process in Montana

Learn moreShow less

Montana distinguishes collection by successor affidavit from informal or formal probate in District Court. A small personal-property collection process does not establish title to every inherited asset. Use Montana's current probate forms and statutory conditions.

Ask about affidavit collection and how the First Judicial District's local rules apply if a probate proceeding is needed.

Montana successor-affidavit collection is distinct from informal appointment through District Court. An affidavit's statements about entitlement and the absence or status of administration must be supported by the facts. A sole-named bank account and a deeded property can require different authority. When probate is needed, distinguish the opening application and letters from subsequent administration and closing documents rather than assuming one packet settles all duties.

State estate and inheritance tax

Learn moreShow less

Montana does not currently impose a state estate tax for 2026 deaths and does not currently impose a separate inheritance tax for 2026 deaths. This does not mean the inheritance or its future earnings are exempt from federal estate, income, or capital gains tax. Property and a decedent connected to another state can require another state's review. Older deaths can have different rules.

Montana Revenue's estate and inheritance guidance distinguishes current no-transfer-tax treatment from older death-date cases. That distinction does not exempt trust income or later asset disposals from tax.
