Montana Estate Planning: Free Wills, Forms & Tools

Estate planning in Montana involves navigating a specific set of state laws that differ in important ways from neighboring states. Understanding these distinctions helps ensure your documents will be valid and your wishes carried out as intended.

Like all states, Montana recognizes formally executed wills and living trusts as valid estate planning tools. A standard will here requires 2 adult witnesses, and adding a notarized self-proving affidavit can streamline the probate process later. The state also recognizes holographic (handwritten) wills, though these have stricter proof requirements and are more vulnerable to legal challenges.

If you die without a will in Montana, your heirs must survive you by at least 120 hours to inherit anything. This "survival period" exists to prevent property from passing through multiple estates in quick succession when family members die close together in time, such as in an accident. The amount a surviving spouse inherits without a will depends on whether your parents are still alive. If they are, your spouse may have to share the estate with them—a result that surprises many people and underscores why having a will matters. Montana uses "per capita at each generation" distribution when dividing assets among descendants. This modern approach ensures that grandchildren whose parent predeceased you share equally with other grandchildren, rather than splitting only their parent's portion.

Smaller estates under $100,000 can use a simplified transfer process that avoids full probate proceedings.

Montana does not impose a state estate tax or inheritance tax, which means estates are only subject to the federal estate tax (currently exempting the first $15,000,000 per person, or $30,000,000 for married couples using portability). This is a meaningful advantage over the states that layer their own death taxes on top of the federal system.

Montana allows transfer-on-death deeds for real estate, enabling property to pass directly to named beneficiaries without probate. This is a significant probate avoidance tool that doesn't require creating a trust. Transferring property into a revocable trust does not trigger a property tax reassessment in Montana, so property taxes remain at their current level.

Montana provides a statutory homestead exemption protecting up to $425,828 in home equity from creditors. While not as strong as the constitutional protections in states like Texas or Florida, this still provides meaningful protection for the family home. Executors must publish a notice to creditors, who then have 4 months to file claims against the estate.

Montana automatically revokes an ex-spouse as beneficiary on life insurance, retirement accounts, and similar designations upon divorce. However, these automatic revocations can be overridden by a divorce decree or by re-designating the ex-spouse after the divorce. Montana does not protect inherited IRAs from creditors. Unlike the owner's own retirement accounts, inherited IRAs in Montana are vulnerable to creditor claims, which is an important consideration when naming beneficiaries.

Montana authorizes remote online notarization (RON), allowing trusts, healthcare directives, powers of attorney to be notarized via video call from anywhere. However, wills are excluded from RON and still require in-person notarization.
