Your Montana Executor Checklist

Step 1: Immediate Actions (First 7 Days)

Before you file anything with the court, there are things that need to happen right away. These protect the estate and protect you.

Order death certificates. Order 10-15 certified copies from the Montana Department of Public Health and Human Services or the funeral home. Banks, insurance companies, the DMV, and brokerage firms each want their own original. Certified copies cost approximately $14 each in Montana.

Secure the property. If the deceased owned a home or ranch, make sure it's locked, the mail is being collected, and nothing is deteriorating. Montana's climate can be brutal on unoccupied property — check that heating systems are running, pipes are protected, and homeowner's insurance is current. If there's livestock or agricultural equipment, arrange for immediate care and security.

Locate the original will. You need the original, not a copy. Check the deceased's home, their attorney's office, and any safe deposit box. In Montana, the original will must be delivered to the Clerk of District Court in the county where the deceased lived, whether or not you open probate. This is a legal requirement under Montana Code Annotated 72-3-202.

Notify immediate family. Let beneficiaries and close family members know you've been named personal representative and that you'll be managing the probate process. You don't need to share financial details yet — just that you're handling things and will keep everyone informed. Setting expectations early reduces the communication burden significantly.

Gather financial records. Start collecting bank statements, investment account information, mortgage documents, ranch or farm financial records, credit card statements, tax returns, and insurance policies. Montana estates often involve agricultural assets or mineral rights, so be thorough.

Step 2: Determine If Full Probate Is Required

Montana is a Uniform Probate Code (UPC) state, which means it offers multiple paths for settling an estate — some of which are remarkably simple.

Collection by affidavit (MCA 72-3-1101). Montana offers two simplified paths. For personal property collection by affidavit, the value of the entire estate (wherever located, minus liens and encumbrances) must not exceed $50,000. You must wait 30 days after death before using this method. For estates up to $100,000 (minus liens), Montana allows summary administration — a simplified probate process with less court involvement. Both options can save significant time and expense.

Informal probate. This is the most common path in Montana. Informal probate doesn't require a court hearing — you file an application with the Clerk of District Court, and if everything is in order, the clerk issues your appointment. This can happen the same day you file, making Montana one of the fastest states for getting your letters.

Formal probate. If there's a dispute about the will, disagreement about who should serve as personal representative, or other contested issues, the estate goes through formal probate before a judge. This is slower but necessary when conflicts exist.

Non-probate transfers. Assets with named beneficiaries, jointly held property, and trust assets all pass outside probate. Montana also recognizes transfer-on-death deeds for real estate and beneficiary deeds, which can move property without probate.

Step 3: File the Will and Petition for Probate

This step officially starts the probate process in Montana.

File an Application for Informal Probate. For most Montana estates, you'll file an application for informal probate of the will and appointment as personal representative with the Clerk of District Court in the county where the deceased lived.

Pay the filing fee. Montana probate filing fees range from $70 to $200, depending on the county. This is very affordable compared to many other states.

Receive your appointment quickly. Montana's informal probate system allows the clerk to process your application and issue Letters of Personal Representative without a hearing. In many counties, this happens the same day you file. These letters are your legal authority to act on behalf of the estate.

Bond may be waived. Montana follows UPC rules on bonding — if the will waives the bond requirement, the court generally respects that. If no waiver exists, the court may require a bond based on the estate's value. Bond premiums are paid from estate funds.

For context on what the overall process looks like, our general executor checklist covers the phases that apply in every state.

Step 4: Publish Notice and Notify Creditors

Montana law requires you to notify creditors and interested parties that probate is underway.

Publish a notice. You must publish a notice of your appointment as personal representative in a newspaper of general circulation in the county where the case is filed. This notice runs for 3 consecutive weeks. Cost is typically $75-$200, depending on the newspaper.

Send notice to known creditors. After your appointment, mail written notice to every creditor you're aware of. The notice must inform creditors of the deadline to file claims and provide the court address for filing.

The creditor claim window: 4 months. In Montana, creditors have 4 months from the date of first publication to present claims against the estate. If you mail individual notice to a known creditor, they have the later of the 4-month deadline or 60 days from the mailing. Understanding how debt works after someone dies helps you evaluate incoming claims.

Notify interested persons. Everyone named in the will and anyone who would inherit under Montana intestacy law must receive notice. Beneficiaries have specific legal rights, including the right to request information and to challenge the will.

Step 5: Inventory and Appraise Assets

This is where you account for everything the deceased owned.

Prepare an inventory. Montana requires the personal representative to file an inventory of all estate assets within 3 months of appointment. The inventory lists each asset with its fair market value as of the date of death.

Value assets at fair market value. For real estate, you'll typically need a professional appraisal. For agricultural land, consider both the market value and the agricultural use value. For vehicles, use Kelley Blue Book or NADA guides. For bank accounts and investments, use values as of the date of death.

Montana does not require a court-appointed appraiser. You can determine asset values yourself or hire independent appraisers as needed. For complex assets like mineral rights, ranch operations, or timber land, professional appraisal is strongly recommended.

Montana-specific assets to watch for. Montana estates frequently include mineral rights, water rights, grazing permits, and agricultural equipment. These assets require specialized valuation. Mineral rights in particular can be surprisingly valuable — make sure to check county records for any mineral reservations.

Step 6: Pay Debts, Taxes, and Expenses

Once the creditor period is running, handle claims methodically.

Evaluate creditor claims. Review each claim carefully. You can accept valid claims, negotiate, or reject invalid ones. Rejected creditors have 60 days to file a lawsuit. Montana law establishes a priority order for paying claims if the estate is insolvent.

Montana has no state estate tax or inheritance tax. Montana does not impose any state-level death tax. You only need to worry about federal estate tax if the estate exceeds the federal exemption — currently $15 million. The vast majority of Montana estates owe nothing in death taxes.

File the decedent's final income tax return. The deceased's final federal and Montana state income tax returns are due by April 15 of the year following death. Montana has a graduated state income tax. If the estate generates income during probate (rental income from agricultural land, mineral royalties, investment dividends), you'll also need to file a separate estate income tax return (federal Form 1041 and Montana Form FID-3).

Pay valid debts and estate expenses. Pay valid creditor claims, ongoing expenses (utilities, insurance, property taxes, livestock care), and probate costs from estate funds. Keep detailed records of every payment.

Step 7: Distribute Assets and Close the Estate

You're in the final stretch — and Montana's UPC framework makes closing simpler than most states.

Choose your closing method. Montana offers two options:

• Closing by sworn statement (informal closing): After the estate has been open for at least 6 months, you can file a verified closing statement without a court hearing. This is the simpler path and works for most uncontested estates.
• Formal closing with court approval: If there are disputes or you want the added protection of a court order, petition for a formal closing with a judicial hearing.

Prepare a final accounting. Whether you close formally or informally, prepare a complete accounting of all transactions — income received, debts paid, fees charged, and the proposed distribution to each beneficiary.

Distribute assets according to the will. After preparing the accounting, transfer assets to beneficiaries as directed. For real estate, prepare and record deeds. Get signed receipts from each beneficiary.

File the closing statement. File your closing statement with the Clerk of District Court. In informal closing, beneficiaries and creditors have 6 months after the statement is filed to contest it. After that period, your appointment terminates and your liability ends.

Montana-Specific Probate Rules to Know

Beyond the step-by-step process, several Montana-specific rules can affect how you manage the estate.

UPC terminology. Montana uses UPC terminology — the executor is called the "personal representative," and the court issues "Letters of Personal Representative" rather than "Letters Testamentary." The substance is the same, but the terminology matters on official documents.

Informal probate is fast. Montana's informal probate system is one of the most efficient in the country. Same-day appointments are common, and the process operates with minimal court oversight. For straightforward estates, this means significantly less time and expense.

Personal representative compensation. Montana allows "reasonable compensation" for personal representatives. There's no statutory fee schedule — compensation is based on the time spent, the complexity of the estate, and customary rates in the community. For more on how executor compensation works across states, see our detailed guide.

Augmented estate and elective share. Montana follows the UPC's augmented estate concept for spousal protection. The surviving spouse can claim an elective share based on the length of the marriage, ranging from 3% (married less than 1 year) to 50% (married 15+ years) of the augmented estate.

Generous small estate options. Montana offers two simplified paths: a small estate affidavit for estates under $50,000 (minus liens) that avoids probate entirely, and summary administration for estates under $100,000 (minus liens) that simplifies the court process significantly.

Mineral rights and water rights. Montana estates frequently involve mineral rights and water rights, which are considered real property and must be specifically addressed in the inventory and distribution. These rights can be separated from surface ownership and may have significant independent value.

FAQ

How long does probate take in Montana?

Most Montana estates take 6-12 months from filing to final distribution. Informal probate can move quickly — simple estates sometimes close in 6-8 months. The 4-month creditor period and 6-month minimum before filing a closing statement create a built-in timeline. Complex estates involving ranch operations, mineral rights, or family disputes can take 12-18 months.

What is informal probate in Montana?

Informal probate is a streamlined process available in Montana as a UPC state. You file an application with the Clerk of District Court, and if everything is in order, you receive your appointment without a court hearing — often the same day. The clerk reviews the paperwork and issues Letters of Personal Representative. This is faster, simpler, and less expensive than formal probate.

Do I need a lawyer for probate in Montana?

No — Montana allows pro se (self-representation) in probate. Montana's UPC-based system is more straightforward than many states, and informal probate is designed to be accessible. However, for estates involving complex assets like mineral rights, ranch operations, or significant real estate, a probate attorney can be valuable. Attorney fees come from the estate.

How much does probate cost in Montana?

The major costs include:

• Court filing fee: $70 -- $200
• Newspaper publication: $75 -- $200
• Attorney fees: Varies (reasonable compensation)
• Death certificates: ~$14 per copy
• Appraisal fees: Varies if professional appraisal needed

Montana has no state estate or inheritance tax, no court-appointed appraiser fee, and relatively low filing fees.

What is the small estate threshold in Montana?

Montana offers two simplified options. The small estate affidavit applies to estates valued at $50,000 or less (minus liens and encumbrances) — you can transfer personal property after a 30-day waiting period without any court involvement. For estates valued at $100,000 or less (minus liens), summary administration provides a simplified probate process with less court oversight.

Can I avoid probate in Montana?

Yes, several strategies can help:

• Living trust: Assets in a revocable living trust pass outside probate
• Joint ownership with right of survivorship: Property passes automatically
• Beneficiary designations: Life insurance, retirement accounts, and POD accounts bypass probate
• Transfer-on-death deeds: Montana allows TOD deeds for real estate
• Small estate affidavit: Estates under $50,000 can skip probate; under $100,000 qualifies for summary administration

Can the executor live outside Montana?

Montana allows non-resident personal representatives without special restrictions. If you're managing an estate from out of state, Montana's informal probate system and minimal hearing requirements make it somewhat easier than many states. Still, consider hiring a local attorney for property management and filing assistance.

What happens if there is no will in Montana?

If someone dies without a will in Montana (intestate), the estate is distributed under Montana's intestacy statutes. The surviving spouse's share depends on whether the deceased had surviving descendants and whether those descendants are also descendants of the surviving spouse. If there are no descendants, the spouse typically inherits the entire estate. The court appoints an administrator.
