Someone died in Montana.
Do you need probate?

Here's what the wizard checks. Montana's four probate tracks, from fastest to full:

Montana enacted the Uniform Real Property Transfer on Death Act in 2019 (MCA §§ 72-6-401 through 72-6-418), and it's become one of the most powerful estate planning tools available to Montana landowners. The optional form of the TOD deed is even codified in the statutes themselves at MCA § 72-6-415.

Here's how a Montana TOD deed works:

During your lifetime: You sign and notarize the TOD deed and record it with the county clerk and recorder before you die. The deed has zero effect while you are alive — your beneficiary has no ownership rights, cannot stop you from selling the property, and cannot prevent you from taking out a mortgage. You can revoke the TOD deed at any time.

At death: The property transfers automatically to the named beneficiary — no probate required. The beneficiary records an affidavit of death (certifying the owner's death) along with a certified death certificate, a Realty Transfer Certificate (Form 488 from mtrevenue.gov), and the original recorded TOD deed. They do not need Letters Testamentary, a personal representative, or a court proceeding.

For ranch families with mineral rights: Montana's TOD deed also works for mineral interests held as a separate estate — a significant advantage in a state with extensive subsurface mineral ownership. MSU Extension's MontGuide on Transfer on Death Deeds in Montana at apps.msuextension.org provides detailed examples for tenants in common, joint tenants, and mineral rights co-owners.

The 30-day small estate affidavit

For personal property, Montana's small estate affidavit (MCA § 72-3-1101) has a standout feature: the waiting period is 30 days after death — the standard UPC period, the same as most other states including Idaho (Montana's neighbor). It can make a significant difference when surviving family members need immediate access to funds for funeral costs or daily expenses.

The affidavit threshold is $100,000 in personal property, net of liens and encumbrances (MCA § 72-3-1101(1)(a)), and no personal representative may have been appointed. Summary administration (MCA § 72-3-1103) is a distinct procedure — not a higher dollar tier — available once a personal representative is appointed, when the estate's value net of the homestead allowance, exempt property, family allowance and administration, funeral and last-illness costs does not exceed those allowances and costs. It has no fixed dollar ceiling. The affidavit works only for personal property — real estate requires a TOD deed, JTWROS, a trust, or probate.

One practical tip: the 30-day affidavit works for bank accounts, vehicles, and personal property held only in the decedent's name. Take the completed affidavit — stating that you are entitled to the property and that the estate qualifies — along with a certified death certificate to the institution holding the assets. Montana law requires them to honor the affidavit (MCA § 72-3-1101). You don't need court approval. You can get certified death certificates through the Montana Department of Public Health and Human Services Vital Records at dphhs.mt.gov/vitalrecords.

Montana sets no statutory attorney fee percentage. Fees must be "reasonable" based on the actual services rendered. This is better for simple estates (you pay only for what's needed) but harder to budget without knowing the attorney's hourly rate and the estate's complexity. Ranch estates with multiple heirs, water rights disputes, mineral interest divisions, or out-of-state property routinely cost more than the typical residential estate.

All Montana probate forms are available at the Montana Judicial Branch end-of-life forms page at courts.mt.gov/forms/endoflife. Free form assistance is available through the Montana Court Help Program at courts.mt.gov/selfhelp at (406) 841-2975. The Montana DPHHS Legal Service Developer Program also provides will templates and other estate planning forms at 1 (800) 332-2272.

Montana is a common law (equitable distribution) state — not a community property state. Unlike Idaho or Washington, there's no automatic spousal share of real estate ownership during marriage. Each spouse owns whatever is titled in their name. This makes title planning especially important for Montana families, particularly for ranch properties that have been in one family's name for generations.

Montana's intestate succession formula for a surviving spouse is more nuanced than most states' simple "spouse gets everything" rules. The outcome depends on whether the decedent had children from a prior relationship, whether the surviving spouse also has children from a prior relationship, and whether the decedent's parents survived the decedent.

Montana's elective share — the right of a surviving spouse to override a will that leaves them too little — ranges from 3% to 50% of the augmented estate, based on the length of the marriage (MCA § 72-2-205). A spouse married for 15 or more years is entitled to 50% of the augmented estate. The augmented estate includes both probate and certain non-probate assets. This sliding scale, based on years of marriage, comes from the Uniform Probate Code and is designed to reflect the economic partnership built over a long marriage. See the Montana LawHelp probate guide at montanalawhelp.org for the full elective share table.

Holographic wills are valid. In Montana, a will where the signature and material provisions are entirely in the testator's handwriting is valid without any witnesses (MCA § 72-2-522). This is common in rural ranch communities where people write their wishes in longhand. However, holographic wills are harder to probate and easier to challenge than properly witnessed and notarized wills. An unwitnessed holographic will cannot be made "self-proving." For anyone with significant real property, a properly executed formal will is strongly preferable.

Water rights are a separate legal estate. In Montana, water rights are appurtenant to land but can also be held as a separate property interest. When a landowner dies, water rights associated with real property should be specifically addressed in the estate plan — both in the TOD deed (for real property) and in a separate conveyance document if water rights are held separately. A Form 640 (certification of water right ownership update) must be filed with the Montana Department of Natural Resources and Conservation (DNRC) at dnrc.mt.gov when water rights change hands. Failure to update water right ownership can cloud title for future transfers.

Ancillary probate for out-of-state Montana residents. If a Montana nonresident dies owning real estate in Montana, their estate must open ancillary probate in the Montana District Court where the property is located (MCA Title 72, Chapter 4). This is common for vacation property owners from Colorado, California, or Washington who have a Whitefish lake cabin or Yellowstone-area ranch.

Public Administrator counties. In very small Montana counties without a willing personal representative, a county Public Administrator may be appointed to handle the estate under MCA Title 72, Chapter 15. This is Montana's safety net for estates that would otherwise go unadministered.

Montana recognizes common law marriages established in states that recognize them. A common law marriage validly formed in another state will be recognized in Montana for purposes of spousal inheritance rights and intestate succession. This can affect intestate succession for families who lived in Colorado or other states where common law marriage is recognized before moving to Montana.

Mineral rights TOD deed — unique Montana planning opportunity. Because Montana has extensive subsurface mineral ownership (oil, gas, coal, copper — the Copper King legacy runs deep), the ability to transfer mineral interests by TOD deed (MCA §§ 72-6-401–418) is particularly valuable. A landowner can record a TOD deed for their surface rights and a separate TOD deed for mineral interests to different beneficiaries — or the same — without probate on either interest. See MSU Extension's MontGuide on TOD deeds for examples involving tenants in common mineral interests.
