Estate Planning After Moving to Montana: What to Update

If you moved to Montana from another state, your existing will is probably still valid. Montana recognizes out-of-state wills that were properly executed under the laws of the state where they were signed (MCA 72-2-523). But a valid will is only one piece of an estate plan — and the other pieces almost certainly need updating.

Montana's legal framework has several features that differ significantly from other states, and each difference creates a potential gap in your coverage.

Four Changes That Matter Most

1. Montana Is a Common Law Property State

If you moved from a community property state — Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, or Wisconsin — this is the most important change to understand.

In your former state, assets acquired during marriage were presumptively owned 50/50 by both spouses. In Montana, ownership follows the title. If your spouse's name is the only one on a bank account or deed, that asset belongs to your spouse alone.

But Montana's Uniform Disposition of Community Property Rights Act (MCA 72-9-101) adds a wrinkle: assets you brought to Montana that were community property in your previous state may retain their community property character for inheritance purposes. This means your Montana estate plan needs to track which assets are "imported" community property and which are Montana separate property — a distinction your former state's plan never needed to make.

2. Transfer on Death Deeds

Montana adopted the Uniform Real Property Transfer on Death Act, allowing you to record a TOD deed that transfers your home directly to a beneficiary at death — no probate, no trust required. If you came from a state without TOD deed legislation, you may not know this tool exists.

Recording a TOD deed on your Montana real property costs $20 for the first page at the County Clerk and Recorder. The deed is revocable during your lifetime and takes effect only at death. For homeowners whose primary asset is their house, this single filing can eliminate the need for probate entirely.

If you already had a beneficiary deed or TOD deed in your former state, it doesn't transfer to Montana. You need a new deed that complies with Montana's specific requirements under MCA 72-6-408, including a proper legal description of the Montana property (street addresses are not sufficient).

3. The Advance Health Care Directive Registry

Montana offers something most states don't: a centralized End-of-Life Registry maintained by the Montana Department of Justice. You can register your Advance Health Care Directive so that any hospital or medical provider in Montana can access your wishes electronically in an emergency.

Your former state's advance directive is likely still legally recognized in Montana — most states honor out-of-state directives. But it won't be in the Montana registry, which means Montana hospitals may not find it when they need it. Executing a Montana-specific directive and registering it provides the strongest protection.

Registration is free. You mail the completed directive and a signed Consumer Registration Agreement to the Department of Justice in Helena.

4. No State Estate or Inheritance Tax

If you moved from a state with an estate tax (Connecticut, Hawaii, Illinois, Maine, Maryland, Massachusetts, Minnesota, New York, Oregon, Rhode Island, Vermont, Washington, or D.C.) or inheritance tax (Iowa, Kentucky, Maryland, Nebraska, New Jersey, Pennsylvania), Montana's tax landscape is simpler. Montana eliminated its state estate tax for deaths after December 31, 2004, and has never imposed an inheritance tax.

This may affect your estate plan's structure. Tax-motivated trusts or complex estate splitting strategies designed to minimize your former state's estate tax may no longer be necessary. Simpler structures (will plus beneficiary designations) may now be sufficient and less expensive to maintain.

What Stays the Same

Not everything needs updating:

• Federal estate tax still applies if your estate exceeds $13.61 million (2026). Montana-specific planning doesn't change the federal calculation.
• ERISA-governed retirement accounts (401(k), 403(b)) follow federal rules regardless of which state you live in.
• Life insurance beneficiary designations generally work the same way across states, though you should confirm the policy is licensed in Montana.

The Medicaid Warning

If you're approaching retirement age, be aware that Montana's Medicaid Estate Recovery Program uses an "expanded estate" definition under MCA 53-6-167. Unlike some states that limit recovery to probate assets, Montana can recover from non-probate assets including TOD deeds, joint tenancy property, and POD bank accounts. If Medicaid planning was part of your estate strategy in your former state, the rules may be more aggressive here.

Practical Steps for New Montana Residents

1. Don't panic. Your existing will is almost certainly valid. You don't need to rush.
2. Review property titles. Understand how every significant asset is titled under Montana's common law system.
3. Record a TOD deed on your Montana home if you want it to pass outside probate.
4. Execute a Montana Advance Health Care Directive and register it with the End-of-Life Registry.
5. Update your powers of attorney. Execute Montana-specific financial and medical powers of attorney. Your out-of-state POA may be challenged by Montana banks or medical providers unfamiliar with your former state's format.
6. Review beneficiary designations. This is a good time to audit every account and make sure designations match your current wishes.

The Montana Basic Estate Planning Kit is built for exactly this situation — a state-specific set of documents that ensures your estate plan works under Montana law, with an assessment section that identifies where your existing plan needs updating.
