A Wyoming durable power of attorney is a written document that lets one person, the principal, name another person, the agent or attorney-in-fact, to handle financial matters on the principal’s behalf. Under Wyoming law it stays in effect if the principal becomes incapacitated, unless the document itself says otherwise.[1.1]

The principal decides which powers to grant, from bank and property transactions to tax matters and investments, and can grant broad authority across all categories or limit those decisions to specific tasks. The principal can change or cancel these decisions at any time before losing capacity. Wyoming law also lets the principal choose when the document takes effect, immediately or at a later date or event.[1.6]
A Wyoming durable power of attorney must be signed by the principal, or by another person signing at the principal’s direction in the principal’s presence. The signature is presumed valid if the principal acknowledges it before a notary public or another official authorized to take acknowledgments. A photocopy or an electronic copy of the signed original counts the same as the original.[1.2][1.3]
Because a photocopy or an electronic copy carries the same legal weight as the signed original, you can give your agent, your bank, or a title company a copy instead of the original document.[1.3] It helps to keep the original somewhere your agent and any health care provider you name can reach it, since some banks and care facilities ask to see it before they act on your agent’s instructions.
Under Wyoming’s power of attorney act, the power of attorney is durable, meaning it stays in effect after the principal becomes incapacitated, unless the document itself states that it terminates on incapacity.[1.1] It takes effect as soon as it is signed, unless the principal states that it should take effect on a future date or event, such as a doctor’s determination of incapacity.[1.6]
State law governs how the power of attorney is read. That is the state named in the document, or, if none is named, the state where it was signed.[1.4]
If a court later appoints a conservator or another fiduciary to manage the principal’s property, the agent remains accountable to that fiduciary as well as to the principal.[1.5]
These rules come from Wyoming’s power of attorney act, part of Title 3, Chapter 9 of the Wyoming Statutes.

A Wyoming durable power of attorney ends when a specific event happens, not simply when a certain amount of time has passed since it was signed. State law sets out five events that end a durable power of attorney, covering everything from the principal’s death to a decision by the principal to revoke the agent’s authority.[1.7]
Separately, the agent’s own authority ends if the principal revokes it, or if the agent dies, becomes incapacitated, or resigns. It also ends if an action is filed to dissolve or annul the agent’s marriage to the principal, unless the document provides otherwise.[1.7]
Wyoming law protects people who rely on the power of attorney in good faith. Termination of the agent’s authority, or of the power of attorney itself, is not effective against the agent or another person who acts in good faith without actual knowledge of the termination. An act performed in good faith under these conditions binds the principal and the principal’s successors.[1.7]
If the power of attorney is not durable, the principal’s incapacity does not revoke or terminate it as to an agent or another person who, without actual knowledge of the incapacity, acts in good faith under it. A lapse of time since the power of attorney was signed does not by itself end the agent’s authority.[1.7]
Signing a new power of attorney does not automatically cancel an earlier one. Under Wyoming law, an earlier power of attorney stays valid unless the new document says it revokes the previous one, or revokes all other powers of attorney. If you want to replace an old power of attorney, put that in writing.[1.7] Tell your agent, your bank, and other institutions directly, since they may keep honoring the old document until they actually know it has ended.
Completing the Wyoming Durable Power of Attorney form means working through each numbered section of the document in order, from naming yourself and your agent to setting the powers you grant and signing before a notary. The steps below follow the form’s own layout, so you can match each one to the matching page as you fill it out.
Enter your full legal name and current address in the opening paragraph of the form (page 1). This identifies you as the principal creating the document.
Enter your agent’s, or attorney-in-fact’s, full name and address (page 1). This is the person you are authorizing to act on your behalf.
Initial each subject line, lettered A through M, for every power you want to give your agent (pages 1-2). Initial the final line instead if you want to grant all of the listed powers at once. Common subject lines include:
Review the four pre-printed clauses on pages 2 and 3. They let your agent access your health care records and handle medical, insurance, and retirement matters on your behalf. Leave each one in place if you want your agent to have that authority, or strike it if you do not:
Initial one of the three listed options on the form: effective immediately, effective on a stated future date, or effective only once you become incapacitated (page 3).
If your agent is unable or unwilling to serve, enter one successor’s name and address in the Successor Attorney-in-Fact paragraph (page 4).
Fill in the date, then sign and print your name (page 4).
Sign before a notary public, who will fill in the county where you signed, the date, and their name and title to complete the acknowledgment (page 5).

Yes. A Wyoming durable power of attorney is durable unless it expressly states that it terminates when the principal becomes incapacitated. That means your agent can continue managing your financial affairs even if you later become unable to make decisions for yourself, as long as the document does not say otherwise. If you want the document to end automatically upon incapacity, say so explicitly when you create it.[1.1]
