Montana — verified requirements

Requirements sourced from primary state statutes and verified by First Light's legal data team.

1
Sign the will in the presence of 2 adult witnesses at the same time. Do not pre-sign the document — your witnesses must watch you sign.
2
Each witness must then sign the will in your presence and in each other's presence. Witnesses must be adults and should not be named as beneficiaries in your will.
Montana does NOT require notarization for a valid will. Witnesses alone are sufficient.
Self-proving affidavit available in Montana — strongly recommended. If a notary is present at signing, your witnesses can sign a self-proving affidavit at the same time. This prevents your witnesses from having to testify during probate. Ask your attorney to prepare one.

Note: Montana recognizes handwritten (holographic) wills, but a typed and witnessed will like the one First Light generates is significantly stronger.

What to Know

  • ·Your will requires 2 witnesses — notarization is not required.
  • ·A self-proving affidavit is available and strongly recommended — it avoids requiring witnesses in probate.
  • ·If you cannot sign, another person may sign on your behalf in your presence and at your direction.
  • ·Divorce automatically revokes your ex-spouse's bequests and executor appointment. Beneficiary designations on insurance and retirement accounts are not affected — those must be updated separately.
  • ·Marriage does not revoke a prior will. Update your will after marrying to include your spouse.
  • ·Children born after your will are automatically entitled to an intestate share, even if not named.
  • ·A spouse not mentioned in your will is entitled to a minimum share under state law.
  • ·Guardian nominations for minor children in your will carry strong weight with courts.
  • ·Estates under $100,000 may qualify for simplified probate.
  • ·Transfer-on-death deeds are available to pass real estate outside probate.
  • ·Handwritten (holographic) wills are recognized but far less reliable than witnessed wills.
1
Sign the Power of Attorney in the presence of a notary public (recommended).
Montana does not require notarization for a valid Durable Power of Attorney. However, notarization is strongly recommended — many banks and financial institutions will refuse to honor a POA without a notary seal.

Tip: Montana has an official statutory POA form. First Light's document is structured to be consistent with Montana's statutory requirements.

What to Know

  • ·Your POA is durable by default — it survives incapacity without special language.
  • ·Springing POAs are permitted — the POA can activate only upon incapacity.
  • ·Remote online notarization is accepted.
  • ·Some financial powers (like changing beneficiaries or managing trusts) must be explicitly granted — a general POA is not enough.
  • ·For real estate transactions, the POA should be recorded with the county recorder.
  • ·Photocopies carry the same legal effect as the original.
  • ·You can nominate a guardian or conservator for yourself in your POA.
1
Sign the Advance Healthcare Directive in the presence of 2 witnesses.
2
Witnesses must be adults. Witnesses should not be:
  • Your Healthcare Proxy
  • A relative by blood or marriage
  • An heir or beneficiary
  • Your attending physician or healthcare provider
  • An employee of a healthcare facility where you are a patient
Montana does NOT require notarization. Two witnesses are sufficient to execute your Healthcare Directive.
After signing, give a copy to your Healthcare Proxy and your primary care physician. Store the original with your other legal documents — not in a safe deposit box that your proxy cannot access.

What to Know

  • ·Your state uses separate instruments for healthcare agent appointment and living will. Both are needed.
  • ·2 witnesses required. Notarization is not required.
  • ·Wet-ink execution is required — electronic signatures are generally not accepted.
  • ·Artificial nutrition and hydration decisions are covered by general treatment preferences.
  • ·A separate HIPAA authorization is recommended so your agent can access your medical records.

What happens if I sign it wrong?

A will or legal document that is not properly executed — missing witnesses, signed in the wrong order, or lacking a required notary — may be declared invalid by a probate court. This means your wishes may not be honored and your estate could be distributed by Montana intestacy law.

Some states have a harmless error doctrine that can save a defectively signed will if the court is satisfied the document reflects your true wishes — but this is never guaranteed and always involves litigation.

The safest approach: follow the signing steps above carefully, and consider having an estate attorney present at signing.
