Montana Homestead Act Exemption: Equity, Filing, and Limits

The Montana homestead exemption protects roughly $425,829 of equity in your primary residence from most creditors in 2026, and you activate it by recording a notarized declaration of homestead with the clerk and recorder in the county where the property sits. The cap grows 4% each calendar year from a $350,000 base the legislature set in 2021.¹ Mortgages, property tax liens, and support obligations still cut through it, so the protection is real but not absolute.

How Much Equity Is Protected

The exemption caps the equity a creditor cannot reach. Starting from the 2021 base of $350,000, the figure compounds by 4% each year, which puts the 2026 amount at approximately $425,829.¹ The Montana Department of Revenue publishes the official figure each year, so confirm the number for your filing year before you rely on it.

Ownership share matters. If you hold only a partial interest in the property, your exemption is proportional to that interest. Two people who each own an undivided 50% each claim an exemption based on their half, not the full cap.¹ Married couples who jointly own one home share a single homestead exemption between them rather than stacking two.

When value is disputed, the assessed value on the most recent completed tax roll is the starting point and is presumed correct unless someone offers evidence to overcome it.¹ That presumption becomes important if a creditor argues your equity climbs above the cap.

What Property Qualifies

The exemption reaches your primary residence: a house on owned land, the structures on it, or a mobile home you live in. A vacation cabin or a rental property does not qualify.

Montana law defines a primary residence as a dwelling you occupy for at least seven months of the year and treat as your genuine, fixed, permanent home, one you intend to return to when you are away. Renting out all or most of the home counts as abandoning it. One narrow allowance: if you leave after January 1 of a given year, the exemption still holds for that tax year, provided you do not rent the property for more than 30 days.²

Active-duty military members get a specific accommodation. If orders require you to relocate, those orders alone preserve your primary residence status for homestead purposes.²

How to File a Declaration of Homestead

The declaration is what formally activates the protection and puts creditors on notice. File as soon as you establish residency, not after financial trouble appears.

Pull the legal description of the property from your recorded deed. The county clerk and recorder keeps searchable real estate records if you no longer have your own copy.³
Complete a declaration that includes the legal description, the owner’s name and address, and a statement that the property is your homestead. The Montana Department of Public Health and Human Services publishes a sample form with instructions.⁴
Sign the declaration in front of a notary public and have it notarized.⁴
Record the notarized declaration with the clerk and recorder in the county where the property sits. The standard recording fee is $20 for the first page and $10 for each additional page.⁵

Keep a copy of the recorded declaration somewhere you can find it. You may need to produce proof of filing if a creditor challenges the exemption later.

What the Exemption Does Not Cover

The exemption blocks unsecured creditors from taking protected equity, but several categories of debt override it entirely.

Mortgages and deeds of trust. A lender that holds a security interest in the home can still foreclose when you default.
Property tax liens. Unpaid property taxes can lead to a tax sale regardless of your homestead filing.
Child support and spousal maintenance. Support enforcement carries higher priority under state and federal law, and a declaration will not shield equity from it.

The protection is on equity, not on the home as an object. If your equity climbs past the cap, a judgment creditor can in theory force a sale, collect the amount above the exemption, and leave you with the protected portion. That is less common now that the cap sits above $425,000, but it remains a real risk for owners with large unsecured debts and substantial equity.

What Happens to Sale Proceeds

Selling does not immediately erase the protection. The exempt portion of your sale proceeds stays shielded from creditors for 18 months after the sale, and the same window applies to condemnation payments and insurance proceeds from damage to the home.⁶

The money has to remain traceable. If you mix the proceeds into general accounts until they cannot be distinguished, the protection breaks down. Montana allows reasonable tracing methods such as first-in-first-out or last-in-first-out accounting.⁶ The cleanest approach is depositing the proceeds in a separate account. If you buy a new home inside the 18-month window, file a fresh declaration on that property.

In J&L Lands, LP v. Nezat, the Montana Supreme Court held that a homeowner receives the full exemption amount from sale proceeds before any money goes toward a judgment lien.⁷ The protected equity comes out first; the creditor takes only what is left.

How You Can Lose the Exemption

Two situations end the protection: voluntary abandonment and extended absence.

To formally abandon a homestead, file a declaration of abandonment with the same clerk and recorder where the original was recorded. Both spouses must sign if you are married; an unmarried owner signs alone.⁸ Without a formal filing, the homestead stays on record even after a move, though courts can still find implied abandonment based on the circumstances.

Renting out all or most of the home counts as abandonment, and that status continues until you physically move back in.² Temporary absences are fine when you keep the intent to return and stay within the seven-month occupancy standard. If a dispute reaches court, judges weigh the totality of the circumstances to decide whether the intent to return was genuine.

The protection also survives death. In In re Estate of Swandal, the Montana Supreme Court held that the homestead exemption can extend to the heirs of a deceased homeowner, so a surviving spouse or family members can still assert it against estate creditors.⁹

Homestead Protection in Bankruptcy

Montana is an opt-out state. A bankruptcy filer must use Montana’s state exemptions rather than the federal exemptions in 11 U.S.C. § 522(d).¹⁰ Your homestead protection in Chapter 7 or Chapter 13 is the same state-law exemption described above.

Federal law adds one significant limit. If you acquired your interest in the property within the 1,215 days (roughly three years and four months) before filing, the exemption is capped at $214,000 for the equity you gained during that window.¹¹ Equity you held before the 1,215-day window is not subject to that federal cap.

There is also a residency test. To use Montana’s exemptions in bankruptcy, you generally need to have lived in the state for at least 730 days (two years) before filing. Newer arrivals may have to use the exemptions of the state they moved from.¹¹

Not the Same as the Homestead Reduced Tax Rate

Montana has a second program called the homestead reduced tax rate, and it is a different thing. The creditor-protection exemption lives in Title 70, Chapter 32 of the Montana Code and is claimed by recording a declaration with the clerk and recorder. The reduced tax rate is a property tax program run by the Department of Revenue that applies tiered rates to a primary residence, starting at 0.76% on the first $378,000 of market value for tax year 2026.¹² Qualifying for one does not enroll you in the other. If you want both, apply for each on its own track.
