Montana Healthcare Power of Attorney Requirements
Montana does not force your Health Care Power of Attorney to wait for a doctor's incapacity finding before your agent can act: under Montana Code Annotated Section 72-5-501, you choose whether it takes effect immediately upon signing and continues through any later incapacity, or only once you become disabled or incapacitated, and the state's own official template defaults to immediate effect.
Introduction
Montana does not force your Health Care Power of Attorney to wait for a doctor's incapacity finding before your agent can act: under Montana Code Annotated Section 72-5-501, you choose whether it takes effect immediately upon signing and continues through any later incapacity, or only once you become disabled or incapacitated, and the state's own official template defaults to immediate effect. This document lets you name someone you trust, called an agent or attorney in fact, to make health care decisions for you, and the Montana Department of Public Health and Human Services publishes the official template that most Montanans use to complete one. Montana handles this differently from many states. Rather than a single combined document, Montana law recognizes two related instruments. This Health Care Power of Attorney can cover any and all health care decisions, and you choose whether it takes effect immediately or only after you become incapacitated. Separately, Montana's Rights of the Terminally Ill Act lets you sign a witnessed Declaration naming a designee who is authorized specifically to decide about withholding or withdrawing life-sustaining treatment if you have a terminal condition. Many people use both together. Montana also runs a voluntary Health Care Declaration Registry through the Attorney General's office, so a Declaration under the Rights of the Terminally Ill Act can be filed and made available to authorized health care providers, though filing is optional and does not affect the document's validity.
Key Things to Know
- 1
Rather than automatically waiting for a doctor to certify incapacity, Montana lets you decide directly in the document whether your Health Care Power of Attorney, which names a trusted adult (your agent) to make health care decisions for you, starts working the moment you sign it or only once you become disabled or incapacitated (Montana Code Annotated Section 72-5-501).
- 2
Montana's own official template defaults to immediate effectiveness, meaning your agent can act right away unless you specify otherwise.
- 3
This document is signed and acknowledged before a notary public. Montana's official template uses no witnesses at all for this general document.
- 4
Montana separately allows a witnessed Declaration under the Rights of the Terminally Ill Act, naming a designee limited to decisions about withholding or withdrawing life-sustaining treatment (Montana Code Annotated Section 50-9-103).
- 5
Montana law does not disqualify any specific category of person, such as a relative or an employee of your care facility, from serving as one of the two witnesses to that Declaration.
- 6
You can revoke a Rights of the Terminally Ill Act Declaration at any time, regardless of your mental or physical condition, once you tell your physician or another health care provider.
- 7
Montana runs a voluntary Health Care Declaration Registry through the Attorney General, where you can file your Declaration so authorized providers can access it, though filing is not required.
- 8
This is a different document from Montana's Uniform Power of Attorney Act, which covers property and financial decisions and by its own terms does not apply to health care decisions.

Montana Requirements for Healthcare Power of Attorney
The principal designates a primary agent to make health care decisions, including that person's full name, address, and contact information, and states clearly that this is a health care power of attorney (Montana Code Annotated Section 72-5-501).
Naming a successor agent who can act if the primary agent is unwilling, unable, or unavailable is standard practice and is included in the state's official template. Montana's coagent and successor-agent statute, Section 72-31-316, applies only to the Uniform Power of Attorney Act's financial powers and by its own terms does not govern a health care power of attorney.
The agent may make decisions about medical treatment, surgical procedures, medication, and facility placement, except as the principal limits that authority in the document.
Federal HIPAA regulations govern how the agent can be authorized to access the principal's protected health information once the document is in effect.
Montana lets the principal choose whether the document is effective immediately and continues through any later disability or incapacity, or becomes effective only upon disability or incapacity (Montana Code Annotated Section 72-5-501). It is not automatically springing on incapacity. Montana's own official template defaults to immediate effectiveness.
Under the Rights of the Terminally Ill Act, a principal may sign a Declaration addressing withholding or withdrawal of life-sustaining treatment, and may designate another individual to make those specific decisions if the principal has an incurable or irreversible condition (Montana Code Annotated Section 50-9-103).
An agent who could have made an anatomical gift on the principal's behalf immediately before the principal's death has priority to make that gift after death (Montana Code Annotated Section 72-17-214). Separately, if a hospitalized prospective donor has a Declaration or advance health care directive, measures necessary to keep an organ medically suitable for transplant may not be withheld or withdrawn unless the Declaration expressly says otherwise (Section 72-17-216).
Electroconvulsive therapy, or surgical or experimental treatment, may be given to a principal who has been determined incapacitated only if a directive explicitly consents to that particular therapy or treatment (Montana Code Annotated Section 53-21-1321). Montana maintains a separate Mental Health Care Advance Directive scheme under Title 53, Chapter 21, Part 13, distinct from the general health care power of attorney, for people who want to authorize or limit mental health treatment specifically.
Montana Code Annotated Section 72-5-502 protects a good-faith agent or third party who relies on the document without actual knowledge of a revocation or of the principal's disability, but it does not itself state a competency requirement for the principal to revoke. Montana's own official template separately requires that the principal be competent to revoke and that revocation be by written notice delivered to anyone relying on the document. This differs from the Rights of the Terminally Ill Act Declaration, which can be revoked in any manner regardless of competency (Section 50-9-104).
Montana's own official Durable Power of Attorney for Health Care template is executed solely by notary acknowledgment, with no witness signatures anywhere in the document. Montana's Mental Health Care Advance Directive, a separate document, does require notarization by statute (Section 53-21-1304).
Montana's own official Durable Power of Attorney for Health Care template entitles the agent to reimbursement for reasonable expenses incurred on the principal's behalf. While the Uniform Power of Attorney Act (Section 72-31-317) provides for agent reimbursement, it does not apply to health care powers of attorney (Section 72-31-303 excludes them from its coverage).
A Declaration executed in a manner substantially similar to Montana Code Annotated Section 50-9-103, in compliance with another state's law, is effective for purposes of Montana's Rights of the Terminally Ill Act (Section 50-9-111).
Facilities that participate in Medicare and Medicaid must ask patients about, and honor, their rights under state law to make advance directives, including a Montana Health Care Power of Attorney.
Life-sustaining treatment cannot be withheld or withdrawn from a patient known to be pregnant, so long as it is probable the fetus will develop to live birth with continued treatment (Montana Code Annotated Section 50-9-106(7)). This provision is part of the statute governing consent when no Declaration exists, so principals should confirm how it interacts with an agent's authority under an executed document.
A principal may nominate, in a durable health care power of attorney, the guardian of the principal's person for the court's consideration if guardianship proceedings are later commenced, and the court must follow that nomination absent good cause or disqualification (Montana Code Annotated Section 72-5-501(2)).
Frequently Asked Questions
A Health Care Power of Attorney in Montana is a legal document, recognized under Montana Code Annotated Section 72-5-501, that lets you name a trusted adult (your agent) to make health care decisions for you. It can cover any and all health care decisions unless you limit it, and you choose whether it takes effect immediately or only once you become incapacitated.
A Health Care Power of Attorney covers only health care decisions. Montana's Uniform Power of Attorney Act, which governs the Durable Power of Attorney for property and financial matters, expressly excludes any power to make health care decisions from its coverage (Montana Code Annotated Section 72-31-303). The two documents are executed and governed separately, and neither one can authorize the other's subject matter.
You choose. Montana Code Annotated Section 72-5-501 lets you word your document so it is effective immediately and continues through any later disability or incapacity, or so that it only becomes effective once you are disabled or incapacitated. Montana's own official Durable Power of Attorney for Health Care template defaults to immediate effectiveness, so read your document closely to see which option it uses.
No. Montana's general Health Care Power of Attorney statute does not set a witness requirement, and the state's own official template is executed by notary acknowledgment only, with no witness signatures. Witnesses come into play only for the separate Rights of the Terminally Ill Act Declaration, which requires two witnesses with no stated disqualifications.
It is a voluntary registry the Montana Attorney General maintains for Declarations made under the Rights of the Terminally Ill Act, accessible through a website the Attorney General runs (Montana Code Annotated Section 50-9-501). You can file your Declaration there so participating health care providers can find it, but filing is optional and does not affect whether your document is valid.
If you signed a Rights of the Terminally Ill Act Declaration, you can revoke it at any time and in any manner, regardless of your mental or physical condition, and the revocation takes effect once you communicate it to your physician or another health care provider (Montana Code Annotated Section 50-9-104). For the broader Health Care Power of Attorney, Montana's own official template asks for written notice delivered to anyone relying on the document while you are still competent to revoke.
Montana's Rights of the Terminally Ill Act requires two witnesses for the Declaration and designee provision, but does not disqualify a relative, a facility employee, or anyone else from serving as one of those witnesses. This is different from many other states, so check your specific document's instructions if you want stricter witness independence.
Only in a limited way. Montana law requires that treatments such as electroconvulsive therapy or surgical or experimental treatment be explicitly authorized in a directive before they can be provided, so a general grant of health care authority is not automatically enough (Montana Code Annotated Section 53-21-1321). Montana also has a separate Mental Health Care Advance Directive scheme under Title 53, Chapter 21, Part 13, for people who want detailed, mental-health-specific instructions.
