Montana Widow & Surviving Spouse Rights

Inheritance rules, elective share deadlines, homestead protections, probate thresholds, and tax realities for surviving spouses in Montana.

For WidowsVerified February 21, 2026

About Montana,

Montana follows common law (equitable distribution) for property classification. This means assets are not automatically split equally -- ownership depends on title, and probate distribution follows intestate statutes or the will.

Without a will, Montana intestate law (MCA § 72-2-112) determines your share. The small-estate threshold is $100,000 for collection of personal property by affidavit., and typical probate takes 6-12 months.

Montana does not impose a state estate tax or inheritance tax, so your exposure is limited to federal estate tax rules if applicable.
