Montana Power of Attorney

A Montana power of attorney is durable by default and valid with your signature alone. A notary is optional, but a bank must accept a notarized one.

By Settled Editorial

A Montana power of attorney names an agent to handle your money and property while you are alive. Montana makes it durable by default, so it keeps working if you lose capacity, and it is valid with nothing more than your signature. A notary is optional for validity. Notarize it anyway, because Montana only forces a bank to accept a power of attorney that a notary acknowledged.

The rules sit in Montana's version of the Uniform Power of Attorney Act, MCA Title 72, chapter 31, part 3, sections 72-31-301 through 72-31-367. Every section cited below was read in the Montana Code Annotated 2025. Use this page as a plain-language map of the statute, then have a Montana attorney draft or review the document you sign, because a power of attorney hands someone real control over your accounts.

One boundary shapes everything else on this site. A power of attorney ends when the principal dies (MCA 72-31-310(1)(a)). The agent's authority stops, and a personal representative appointed through a Montana district court takes over. For what happens after that, start with the Montana probate guide.

Where Montana's Act Lives

The Legislature enacted the Uniform Power of Attorney Act in 2011 (Ch. 109, L. 2011), and it took effect on October 1, 2011. MCA 72-31-367 applies it to a power of attorney created before, on or after that date, other than a health care power of attorney. An older Montana document still runs on these rules today, though an act done before October 1, 2011 is not affected.

Two numbering notes save confusion. The durability rule used to be 72-31-222 in the 2009 code and is now 72-31-304. And part 4 of the same chapter, starting at 72-31-401, is a different law about digital assets, not powers of attorney.

Durable By Default

Some states make you add magic words to keep a power of attorney alive after incapacity. Montana does not. MCA 72-31-304 is one sentence:

A power of attorney created under this part is durable unless it expressly provides that it is terminated by the incapacity of the principal.

Your document has to opt out of durability, in express words, to lose it. MCA 72-31-310(1)(b) mirrors that from the other side, ending a power of attorney on incapacity only if the document is not durable.

Montana defines incapacity at MCA 72-31-302(5) as being unable to manage property or business affairs because of an impairment in receiving and evaluating information or making or communicating decisions, even with technological help, or because you are missing or outside the United States and unable to return. A durable document keeps your bills paid through any of those.

Age does not wear it out either. Under 72-31-310(3), unless the document says otherwise, an agent's authority stays good no matter how long ago you signed.

Signing Rules: A Signature Is Enough

MCA 72-31-305 is the whole execution rule, and it has two sentences. The first sets the requirement: the principal signs, or another individual signs the principal's name in the principal's conscious presence at the principal's direction. The second attaches a benefit: a signature is presumed genuine if the principal acknowledges it before a notary public or another person authorized by law to take acknowledgments.

Here is what the act does not ask for:

  • No witnesses. The two-witness rule belongs to the Montana living will under MCA 50-9-103.
  • No notary for validity. An acknowledgment earns a presumption, not validity.
  • No date line and no signature from the agent. Under MCA 72-31-318 an agent accepts by acting, or by any other conduct showing acceptance.

MCA 72-31-306 turns that into the validity test. A document signed in Montana on or after October 1, 2011 is valid if it complies with 72-31-305. A document signed in another state is valid in Montana if it complied with the law that governs it under 72-31-307, or with the federal rules for a military power of attorney at 10 U.S.C. 1044b. A photocopy or electronically sent copy has the same effect as the original, unless another statute says otherwise.

The act also counts electronic records. MCA 72-31-302 defines a power of attorney as a writing or other record, and defines "sign" to include attaching an electronic symbol or process. Whether your county clerk and recorder or your bank will take an electronically signed or remotely notarized document is a separate question to ask them first.

Why You Should Notarize It Anyway

Four reasons, each written into Montana law.

Banks have to accept only a notarized one. MCA 72-31-324 and 72-31-325 apply to an acknowledged power of attorney, which 72-31-324(1) defines as one purportedly verified before a notary or another person authorized to take acknowledgments. A document without a notary acknowledgment is still valid, but a bank can turn it away without facing the penalties below.

The signature is presumed genuine. That presumption in 72-31-305 is what lets a bank rely on the document under 72-31-324(2).

Real estate needs it. MCA 7-4-2613(1)(a)(i) lists powers of attorney to convey real estate among the documents the county clerk records. MCA 70-21-203 then says that, outside two narrow classes (court judgments and government title documents), an instrument's execution must be acknowledged or proved before it can be recorded. An agent selling your house will usually need a recordable document.

The state's own form expects it. The statutory form in 72-31-353 ends in a notary block. The free Financial Power of Attorney form from the Montana DPHHS Legal Services Developer Program, linked from the State Law Library forms page, tells you to sign it in front of a notary. That is sound advice even though 72-31-305 does not make it a condition of validity.

Banks Get Seven Business Days

Montana pairs a shield for whoever accepts the document with a penalty for whoever stalls.

Under 72-31-324(3), a person who in good faith accepts an acknowledged power of attorney, without actual knowledge that it is void, invalid or terminated, or that the agent is overstepping, may rely on it as if it were genuine and still in force. Under 72-31-324(4), that person may ask for, and rely on without further checking, an agent's certification under penalty of perjury, an English translation, or an opinion of counsel if the reason is given in writing.

Then 72-31-325(1) supplies the clock. The person must accept, or ask for one of those items, within 7 business days after presentation, and must accept within 5 business days after receiving the item. Nobody may demand an additional or different form of power of attorney for authority the presented document already grants.

Six grounds excuse a refusal under 72-31-325(2):

  1. The person is not otherwise required to do business with the principal in the same circumstances
  2. Doing the transaction would be inconsistent with federal law
  3. The person actually knows the power of attorney or the agent's authority has ended
  4. A request for a certification, translation or opinion of counsel was refused
  5. The person believes in good faith that the document is not valid or the agent lacks authority for the act
  6. The person made, or knows someone made, a report to the local office of the Department of Public Health and Human Services stating a good faith belief that the agent may be abusing, neglecting, exploiting or abandoning the principal

A refusal outside those grounds exposes the person to a court order mandating acceptance and to the reasonable attorney fees and costs of the proceeding (72-31-325(3)).

Immediate Or Springing

A Montana power of attorney works the day you sign it. MCA 72-31-309(1) makes it effective when executed unless the document says it starts at a future date or on a future event.

If you want a springing document, name who decides. Section 72-31-309(2) lets you authorize one or more people to decide in writing that the event happened. If the document springs on incapacity and you named nobody, or the person you named cannot or will not decide, 72-31-309(3) supplies a fallback:

  • A physician decides the impairment limb of the incapacity definition.
  • An attorney at law, a judge or an appropriate governmental official decides the missing or outside-the-United-States limb.

Section 72-31-309(4) lets the person you authorized to make that call act as your HIPAA personal representative to reach the medical records the decision depends on.

Springing documents feel safer and cost you speed. Someone has to produce a written determination before your agent can act, which is a delay at the moment you needed help. That trade is a good question for a lawyer.

Eight Powers That Need Express Words

A general grant does not reach your estate plan. MCA 72-31-336(1) lets an agent do these eight things only if the power of attorney expressly grants the authority, and only if no other agreement or instrument forbids it:

  1. Create, amend, revoke or terminate an inter vivos trust
  2. Make a gift
  3. Create or change rights of survivorship
  4. Create or change a beneficiary designation
  5. Delegate authority granted under the power of attorney
  6. Waive the principal's right to be a beneficiary of a joint and survivor annuity, including a survivor benefit under a retirement plan
  7. Exercise fiduciary powers that the principal has authority to delegate
  8. Disclaim property, including a power of appointment

This is where the Montana form differs from forms you find online. The uniform act's model form carries a separate initialed block for these powers. The Montana statutory form in 72-31-353 has none. It goes straight from the list of general subjects to the limitation on the agent's authority and the Special Instructions lines. If you want your agent to make gifts, change a beneficiary or touch your trust, you have to write that grant into the Special Instructions.

Section 72-31-336(2) adds a guard. Unless the document says otherwise, an agent who is not your ancestor, spouse or descendant may not use those powers to create an interest in your property for the agent or for someone the agent must legally support. The form repeats that under the heading LIMITATION ON AGENT'S AUTHORITY.

Three more rules finish the section. A grant to do all acts you could do gives the general authority of 72-31-339 through 72-31-351, and nothing more (72-31-336(3)). Where granted subjects overlap, the broadest authority controls (72-31-336(5)). And the authority reaches property you own at signing or acquire later, in Montana or elsewhere (72-31-336(6)).

Gifts Follow A Federal Cap

Montana writes no dollar figure for gifts. Under MCA 72-31-352(2), unless the document says otherwise, general gift authority lets the agent give per donee no more than the annual federal gift tax exclusion under 26 U.S.C. 2503(b), or twice that if your spouse agrees to split the gift under 26 U.S.C. 2513. The cap moves when the IRS adjusts the federal exclusion.

Section 72-31-352(3) also limits why a gift is made. The agent gives only as fits your objectives, if known, and otherwise your best interest, weighing your property, your foreseeable needs, taxes, eligibility for public benefits, and your own history of giving. If you want a different scale of giving, say so in the document.

What Your Agent Owes You

MCA 72-31-319 sorts the agent's duties into two groups.

Duties your document cannot switch off (72-31-319(1)): act on your reasonable expectations as far as the agent knows them and otherwise in your best interest, act in good faith, and act only within the authority granted.

Duties your document can change (72-31-319(2)): act loyally for you, avoid conflicts that impair impartial judgment, use the care, competence and diligence ordinarily expected of agents, keep a record of all receipts, disbursements and transactions, cooperate with whoever makes your health care decisions, and try to preserve your known estate plan when that fits your best interest.

Section 72-31-319(8) is the accountability valve. The agent does not have to share records unless a court orders it or one of these asks: you, a guardian, a conservator, another fiduciary acting for you, a protective government agency, or, after your death, your personal representative. Once asked, the agent has 30 days to comply or explain in writing why more time is needed, and then 30 more days to comply.

Three companion sections round it out. MCA 72-31-317 entitles the agent to reimbursement of reasonable expenses and to compensation that is reasonable under the circumstances, with no fee schedule. MCA 72-31-316 lets coagents act independently unless you say otherwise, and lets a successor act only after every earlier agent has resigned, died, become incapacitated, become unqualified or declined. An agent who learns another agent is breaching a duty must tell you and, if you are incapacitated, take reasonable steps to protect you (72-31-316(4)).

The Montana Statutory Form

MCA 72-31-353 prints the Montana Statutory Form Power of Attorney. A document that closely follows that form carries the meaning the act gives it. Using it is optional.

You grant general authority by initialing any of 13 subjects, or one line marked All Preceding Subjects: Real Property, Tangible Personal Property, Stocks and Bonds, Commodities and Options, Banks and Other Financial Institutions, Operation of Entity or Business, Insurance and Annuities, Estates, Trusts, and Other Beneficial Interests, Claims and Litigation, Personal and Family Maintenance, Benefits from Governmental Programs or Civil or Military Service, Retirement Plans, and Taxes.

The form's opening notes tell you four things worth knowing. It does not authorize health care decisions. Your agent is entitled to reasonable compensation unless you say otherwise. It names one agent, and a coagent goes in the Special Instructions, where coagents need not act together unless you require it. And it takes effect immediately unless the Special Instructions say otherwise. It also lets you nominate a conservator or guardian for yourself, and it closes with a notary block and a page headed IMPORTANT INFORMATION FOR AGENT, which tells the agent to sign as "(Principal's Name) by (Your Signature) as Agent".

MCA 72-31-354 prints a second optional form, the agent's certification, signed under penalty of perjury before a notary. That is the paper a bank may ask your agent to bring.

How A Montana Power Of Attorney Ends

MCA 72-31-310(1) lists six ways the document itself ends:

  • The principal dies
  • The principal becomes incapacitated, if the document is not durable
  • The principal revokes it
  • The document says it ends
  • Its purpose is accomplished
  • The principal revokes the agent's authority, or the agent dies, becomes incapacitated or resigns, and no other agent is named

Section 72-31-310(2) separately ends an agent's authority. The divorce rule is the one that surprises people: a spouse-agent's authority ends when an action for dissolution, annulment or legal separation is filed, not when the decree is entered, unless your document says otherwise.

Signing a new document does not cancel the old one on its own. Under 72-31-310(6), a later power of attorney revokes an earlier one only if it says the previous one, or all others, are revoked. The Montana section prescribes no method of revocation, so put yours in writing and deliver it. Tell your agent and every bank holding a copy, because 72-31-310(4) protects anyone who acts in good faith without actually knowing the authority ended.

Recorded documents carry an extra step. If a power of attorney to convey real estate was recorded, MCA 70-21-308 says it is not revoked by any act of yours unless the revocation is also acknowledged or proved, certified, and recorded in the same office that recorded the power. A letter to the agent does not clear the county record.

A Conservator Does Not Cancel Your Agent

Montana keeps your agent in place when a court gets involved. MCA 72-31-308(1) lets you nominate a conservator or guardian of your estate, or a guardian of your person, inside the power of attorney. Except for good cause or disqualification, the court appoints according to your most recent nomination.

If a court appoints a conservator or other fiduciary over your property anyway, 72-31-308(2) says the power of attorney is not terminated. The agent keeps acting unless the court limits, suspends or ends that authority, and answers to the conservator as well as to you. That is why a financial power of attorney is the everyday alternative to a court case, covered in Montana guardianship planning.

Health Care Is A Separate Document

MCA 72-31-303(2) takes a power to make health care decisions out of the act, and the statutory form says so on its face. A Montana financial power of attorney cannot carry medical authority, whatever its wording.

Montana appoints a health care agent through a durable health care power of attorney under MCA 72-5-501. Unlike the financial document, it must contain words showing it survives your disability or incapacity. For the health care side, read the Montana advance directive guide. Section 72-31-319(2)(e) then requires your financial agent to cooperate with whoever holds the medical authority.

Section 72-31-303 excludes three other things: a power coupled with an interest, such as one given to a creditor in a loan, a proxy to vote or manage rights in an entity, and a power on a form a government prescribes for its own purpose, such as a tax agency's authorization form.

A Parent's Delegation Lasts Six Months

A different statute covers a parent handing over authority for a child. MCA 72-5-103 lets a parent, or a guardian of a minor or incapacitated person, delegate powers over care, custody or property by a power of attorney for no more than 6 months. The power to consent to marriage or adoption of a minor ward cannot be delegated.

The 6-month cap does not apply to active duty military, or to Montana national guard or federal reserve members serving more than 180 continuous days on duty (72-5-103(2)). The State Law Library lists a Power of Attorney for Care, Custody, and Control of a Minor Child form on its forms page.

When An Agent Misuses The Power

The act's remedy is civil. MCA 72-31-322 makes an agent who violates it liable to you or your successors for what it takes to restore your property to where it would have been, plus the attorney fees and costs paid on the agent's behalf.

MCA 72-31-321 is the door into court. You, the agent, a guardian or conservator, your health care agent, your spouse, parent or descendant, a presumptive heir, a named beneficiary, a protective government agency, a caregiver, or anyone asked to accept the document may ask a court to construe it or review the agent's conduct. A capable principal stays in charge: on your motion the court must dismiss the petition unless it finds you lack capacity to revoke.

Montana's Vulnerable Adult Prevention of Abuse Act defines "exploitation" at MCA 52-3-803 to include the unreasonable use of a power of attorney to take a vulnerable adult's money or property. That is a definition, not a crime by itself. Older articles cite 52-3-825 for a criminal penalty, but the 2025 Legislature repealed that section (Sec. 13, Ch. 484, L. 2025).

A power of attorney keeps your affairs moving during a bad stretch while you are alive. It moves nothing out of probate. For where it sits among your other documents, see Montana estate planning basics, and for tools that do skip probate, read how to avoid probate in Montana.

When To Talk With A Montana Attorney

Bring in a Montana attorney when:

  • You want your agent to make gifts, change beneficiaries or touch a trust, which on the Montana form means writing it into the Special Instructions
  • You own real estate, a business, or property in another state
  • Your family may disagree about who should serve
  • You want safeguards against financial abuse built into the document
  • You are choosing between an immediate document and a springing one
  • You plan to sign electronically or with a remote notary
  • You downloaded a form and cannot tell whether it was written for Montana

This page explains the rules so you arrive with better questions. A lawyer can adapt the statutory form, write the express grants you intend, and make sure the document works on the day your agent needs it.

Frequently Asked Questions

Does a Montana power of attorney have to be notarized?

Not to be valid. MCA 72-31-305 requires only that the principal sign it, or that another person sign the principal's name in the principal's conscious presence at the principal's direction. A notary acknowledgment makes the signature presumed genuine, and MCA 72-31-324 and 72-31-325 protect and require acceptance only of an acknowledged power of attorney. A county clerk also needs an acknowledged document before recording it for a real estate sale under MCA 70-21-203. So notarize it, even though the statute does not make you.

Is a Montana power of attorney durable by default?

Yes. MCA 72-31-304 says a power of attorney created under the act is durable unless it expressly provides that it is terminated by the incapacity of the principal. You need no special durability words. That differs from a Montana health care power of attorney, which under MCA 72-5-501 must contain words showing it survives your disability or incapacity.

Does a Montana power of attorney need witnesses?

No. Nothing in MCA 72-31-305 or the rest of the Uniform Power of Attorney Act asks for a witness. The two-witness rule people remember comes from the Montana living will under MCA 50-9-103, a different document.

Does Montana have an official power of attorney form?

Yes, and using it is optional. MCA 72-31-353 prints the Montana Statutory Form Power of Attorney. You initial any of 13 subjects, or All Preceding Subjects, to grant general authority. The Montana form has no separate block for gifts, trusts or beneficiary changes, so any of those powers has to be written into the Special Instructions. MCA 72-31-354 prints an optional agent's certification.

Can a Montana power of attorney cover medical decisions?

No. MCA 72-31-303(2) takes a power to make health care decisions out of the act, and the statutory form says this power of attorney does not authorize the agent to make health care decisions for you. Montana handles that with a separate durable health care power of attorney under MCA 72-5-501 and 72-5-502.

Does a Montana bank have to accept a power of attorney?

It has to accept an acknowledged (notarized) one, on a clock. MCA 72-31-325(1) gives the bank 7 business days after presentation to accept it or ask for an agent's certification, a translation or an opinion of counsel, and 5 business days after receiving that item to accept. The bank may not demand its own form. Six grounds in 72-31-325(2) excuse a refusal, and an unlawful refusal exposes the bank to a court order and attorney fees under 72-31-325(3).

When does a Montana power of attorney end?

MCA 72-31-310(1) ends it when the principal dies, becomes incapacitated if the document is not durable, revokes it, when the document says it ends, when its purpose is accomplished, or when the last available agent stops serving. Under 72-31-310(2)(c) a spouse-agent's authority ends when an action for divorce, annulment or legal separation is filed, unless the document says otherwise.
