Montana Estate Settlement Timeline: How Long Does Probate Take?

One of the most common questions from families starting the estate settlement process is simple: how long is this going to take? The answer in Montana is more specific than you might expect, because the Uniform Probate Code establishes hard statutory deadlines at multiple points in the process. Missing these deadlines does not just slow things down — in some cases it changes what options are legally available to you.

Here is a concrete, chronologically organized timeline for settling an estate in Montana, based on the actual statutes that govern the process.

Day 0: Death Occurs

The clock starts. Even before any formal legal process begins, several things need to happen immediately:

• Secure the decedent's residence and physical property
• Notify Social Security to halt benefit payments
• Determine who has authority over funeral arrangements under Montana's Right of Disposition Act
• Order certified death certificates ($16 per copy through DPHHS)
• Locate any advance directives through the Montana End-of-Life Registry

The death certificate is the foundational document for everything that follows. Every financial institution, government agency, and transfer agent will require a certified copy. For a typical estate with bank accounts, a vehicle, life insurance, and retirement accounts, plan on ordering at least 8 to 10 certified copies.

Hours 0–120 (Days 1–5): Mandatory Waiting Period

Montana law prohibits filing for informal probate until 120 hours (five days) have passed since the time of death. This is not an administrative delay — it is a statutory requirement built into the Uniform Probate Code.

The 120-hour rule also has a property inheritance function: an heir must survive the decedent by 120 hours to inherit under Montana law. If an heir died in the same accident as the decedent and did not survive by 120 hours, that heir is treated as having predeceased the decedent for inheritance purposes.

During this window, the nominated Personal Representative should be gathering documents, locating the will, identifying account numbers, and preparing the informal probate application — so filing can happen as soon as the waiting period clears.

Day 5 and Beyond: Filing Informal Probate

Once 120 hours have passed, the nominated Personal Representative can file the Application for Informal Probate with the Clerk of the District Court in the county where the decedent was domiciled. The filing fee is $100.

The filing package includes:

• Application for Informal Probate
• Original will (if the estate is testate)
• Certified death certificate
• Fiduciary Statement signed by the Personal Representative

If the application is complete and uncontested, the Clerk issues a Statement of Informal Probate and Letters of Authority. Letters of Authority are the legal document that empowers the Personal Representative to act — to access bank accounts, transfer property, and represent the estate.

Day 30: Small Estate Affidavit Becomes Available

For estates with $100,000 or less in probate assets, a more direct route exists: the Collection of Personal Property by Affidavit under MCA 72-3-1101. This procedure bypasses the court entirely — no filing, no filing fee, no Letters of Authority.

The affidavit cannot be used until 30 days have passed since the date of death. After that 30-day window, heirs can present the notarized affidavit directly to financial institutions, transfer agents, and other entities holding the decedent's assets to claim them without any court involvement.

Important: the $100,000 threshold applies only to probate assets. Non-probate assets (joint accounts, TOD designations, life insurance) do not count toward this limit.

Month 1–3: First Publication of Creditor Notice

After the Personal Representative receives Letters of Authority, they must publish a Notice to Creditors in a newspaper of general circulation in the county where the probate is filed. The notice must be published once a week for three consecutive weeks.

The first publication of notice starts the four-month creditor claim period.

Month 4–5: Creditor Claim Period Closes

Four months after the first publication of Notice to Creditors, the creditor window closes. Creditors who failed to file a formal claim against the estate by this deadline are permanently barred from collecting.

This is one of the most powerful features of completing the formal probate process. Once the four-month period has run, the Personal Representative can distribute estate assets to beneficiaries with confidence that no late creditor can appear and demand payment.

The Personal Representative must also complete and file an Inventory of the estate within nine months of appointment, detailing all probate assets and their fair market value as of the date of death.

Month 9: Federal Estate Tax Return Deadline (If Required)

If the estate is large enough to require a federal estate tax return (Form 706), the deadline is nine months from the date of death. Extensions are available but must be requested before the deadline.

For most Montana estates — those well below the multi-million dollar federal exemption threshold — no estate tax return is required. Montana has no state estate or inheritance tax.

Month 12: Title Insurance Restriction on TOD Deed Properties

For any real property transferred to a beneficiary via a Transfer on Death (TOD) deed, title insurance underwriters in Montana frequently will not insure the title for a subsequent purchaser until one year has passed from the date of death. This protects underwriters against creditor claims that could attach to TOD property during the first year.

A beneficiary who inherits real property via a TOD deed and wants to sell it immediately may face serious obstacles until this one-year window closes. Planning around this restriction — potentially by opening probate to formally clear creditor claims — is a conversation to have with a real estate attorney before listing the property.

Year 1: Probate Can Be Closed

For most Montana informal probate proceedings, the estate can be formally closed at any point after the creditor claim period has ended and all assets have been distributed. The Personal Representative files a Sworn Statement of Personal Representative Closing the Estate, certifying that the estate has been fully administered.

Montana does not impose a mandatory minimum time for estate administration beyond the creditor notice requirements. A straightforward estate can be opened, administered, and closed in six to nine months if all goes smoothly.

Year 2: Outside Deadline for Closing

If the estate has not been closed within two years of the Personal Representative's appointment, the court may intervene. This is rarely an issue for uncontested estates but becomes relevant when an estate drags on due to disputed assets, litigation, or uncooperative beneficiaries.
