A Montana durable power of attorney is a written document that lets one person, the principal, name another person, the agent or attorney-in-fact, to make financial decisions on their behalf. It is durable, meaning it stays in effect even if the principal later becomes incapacitated, unless the document expressly states otherwise.[1]
The durable power of attorney form can confer wide-ranging authority to the appointed agent, such as banking, real estate transactions, investment management, and tax filings. Alternatively, the principal retains the ability to limit the specific powers.
To create a valid Montana durable power of attorney, choose a trustworthy agent, decide which powers to grant, and sign the document under state law. Use Montana POA templates to build and print your form.

Montana power of attorney forms are durable by default. If you want yours to end automatically if you become incapacitated, you must say so directly in the document, since Montana law otherwise keeps it in effect.[1]
A durable financial power of attorney can be an important estate planning tool in Montana. It allows someone to manage the principal’s affairs if they become unable to do so themselves due to illness or incapacity. However, it grants significant authority, so the agent should be highly trustworthy.

Popular Local Durable POA Forms
Durable POA documents are used in each and every state. Take a look at other popular DPOA forms frequently filled out by Americans.
A Montana power of attorney terminates when the principal revokes it, when the agent’s authority ends, or when certain events occur under state law. As a general rule, the agent’s authority to act can also end on its own. The list below covers the events that trigger revocation or otherwise end a power of attorney or an agent’s authority to act under it.
Termination of the agent’s authority, or of the power of attorney itself, is not effective against someone who acts in good faith without actual knowledge of it.[3] The same rule applies to incapacity. If the power of attorney is not durable, the principal’s incapacity does not revoke it as to a person who acts in good faith without actual knowledge of the incapacity.[3]
The principal may revoke the power of attorney at any time. No special instructions or particular wording are required for this kind of revocation to be valid, but putting it in writing avoids disputes.[3]
Common mistake: signing a new power of attorney does not automatically cancel an earlier one, even if it names the same agent and address. Unless the new document states that it revokes the previous power of attorney, or all previous powers of attorney, the earlier one stays in effect alongside it.[3]
Filling out the Montana durable power of attorney form gives your agent the authority to make financial decisions and handle your affairs. The form follows the order below, from naming your agent through signing and acknowledgment. Follow each step in order and read the notice on page one before you begin.
Provide your name and address as the principal, then name your agent (attorney-in-fact) and their address. The form’s opening notice explains that these powers are broad, so read it carefully before you continue.
The form lists the powers you can grant to your agent. Initial the line in front of each power you want to include, or initial “(N) ALL OF THE POWERS LISTED ABOVE” to grant all of them.
Use the special instructions section to add or limit specific powers, or to include instructions the rest of the form does not otherwise cover. Special instructions can also record decisions about compensation or coagents. Read the pre-written instructions carefully and decide whether to keep or change them.
Initial one of the three options for when the power of attorney takes effect: immediately, on a specific date, or only if you become incapacitated. This decision controls when your agent can begin acting for you.
If you name more than one agent, this section states whether they must act together or may each act separately when they make decisions on your behalf.
Name a successor agent who takes over if your first agent becomes unable or unwilling to serve.
Sign and date the form as the principal, in the manner Montana law requires for a legally valid power of attorney. This is what gives your agent authority to act.[2]
A notary public or another person authorized to take acknowledgments completes the acknowledgment section. Doing this makes your signature presumed genuine under Montana law.[2]
