Montana Will Template: What Makes a Last Will and Testament Valid

Searching for a Montana will template? Before downloading any form, you need to understand what Montana law actually requires — because a will that doesn't meet these requirements is worthless, no matter how professional it looks.

Montana follows the Uniform Probate Code, which makes its will requirements more straightforward than many states. But there are specific rules that generic templates from national websites routinely get wrong.

The Three Legal Requirements Under MCA 72-2-522

A formal witnessed will in Montana must satisfy exactly three conditions:

1. Written and signed by the testator. The person making the will must be at least 18 years old and of sound mind. The will must be in writing — oral wills are not recognized in Montana. The testator must sign the will personally, or direct someone else to sign on their behalf in their conscious presence.

2. Signed by at least two witnesses. Two competent witnesses must sign the will, attesting that they either witnessed the testator sign it or that the testator acknowledged the signature to them. Montana does not require the witnesses to sign in each other's presence — they must sign within a reasonable time of the testator's signing.

3. Testamentary intent. The document must clearly express the testator's intent to distribute their property after death. Ambiguous language can trigger challenges that delay probate for months.

Montana does not require notarization for a will to be valid. However, adding a self-proving affidavit (notarized under MCA 72-2-524) makes probate significantly faster by eliminating the need to locate witnesses after your death.

What a Good Montana Will Template Covers

A template that's actually useful for Montana residents should include sections for:

• Identification and revocation clause — your full legal name, county of residence, and a statement revoking all prior wills
• Specific bequests — particular items or amounts to named individuals
• Residuary clause — who receives everything not specifically mentioned (this catches assets you acquire after signing)
• Personal representative nomination — Montana's term for executor; the person who will administer your estate
• Guardian nomination for minor children — if applicable, naming who should raise your children
• Alternate beneficiaries — backup recipients in case a primary beneficiary predeceases you
• Witness signature blocks — space for two witnesses with their printed names and addresses
• Self-proving affidavit — the notarized statement under MCA 72-2-524 that speeds up probate

Why Generic Templates Fail in Montana

National template services create one-size-fits-all documents that miss Montana-specific requirements:

Personal representative powers. Montana law under MCA 72-3-715 grants personal representatives broad default powers, but your will can expand or restrict those powers. A generic template often omits Montana-specific authority provisions — like the power to deal with agricultural land or mineral rights, which matters enormously for rural Montana estates.

The 120-hour survival requirement. Under MCA 72-2-114, an heir must survive the decedent by 120 hours (five days) to inherit. Your will template should address what happens if a beneficiary dies within that window. Many generic templates don't account for this.

Montana's elective share. You cannot completely disinherit a surviving spouse in Montana. Under MCA 72-2-221, a surviving spouse can claim their elective share regardless of what the will says. A proper Montana will template acknowledges this reality rather than creating false expectations.

Holographic Wills: Montana's Handwritten Alternative

Montana recognizes holographic wills under MCA 72-2-522 — handwritten wills that require no witnesses at all. The signature and all material portions must be in the testator's own handwriting.

This sounds simpler, but holographic wills carry real risks. Without witnesses, they're far more vulnerable to challenges on grounds of authenticity or capacity. Courts must verify the handwriting, which adds time and expense. And "material portions" is a phrase that has generated significant litigation — if you type the beneficiary names and handwrite only the distribution instructions, a court may find the will invalid.

A holographic will is better than no will at all. But for an estate of any complexity, a properly witnessed and self-proved will is substantially safer.

After You Sign: Critical Next Steps

Creating the will is step one. Montana estate planning requires coordinating your will with several other documents:

• Beneficiary designations on bank accounts, retirement accounts, and life insurance override what your will says. If your will leaves everything to your children but your 401(k) still names your ex-spouse, the ex-spouse gets the retirement money.
• Transfer on Death deeds for real property pass real estate outside probate entirely. Your will only controls assets that don't have a beneficiary designation or survivorship provision.
• Powers of attorney and advance health care directives handle decisions while you're alive but incapacitated. Your will has no effect until you die.

The Montana Basic Estate Planning Kit includes the will template along with all of these coordinating documents — designed to work as a system rather than isolated forms that may conflict with each other.

When a Template Isn't Enough

A self-help will template works well for straightforward situations: single marriage, adult children, assets under the federal estate tax exemption ($13.61 million in 2026). You should consult an attorney if you have children from multiple relationships, own a business or agricultural operation with succession concerns, have a beneficiary with special needs, or expect your will to be contested.
