Okla. Stat. tit. 58, § 58-3010: Termination of power of attorney or agent's authority

A. A power of attorney terminates when:

1. The principal dies;

2. The principal becomes incapacitated, if the power of

attorney is not durable;

3. The principal revokes the power of attorney;

4. The power of attorney provides that it terminates;

5. The purpose of the power of attorney is accomplished; or

6. The principal revokes the agent's authority or the agent

dies, becomes incapacitated or resigns, and the power of attorney

does not provide for another agent to act under the power of

attorney.

B. An agent's authority terminates when:

1. The principal revokes the authority;

2. The agent dies, becomes incapacitated or resigns;

3. An action is filed for divorce or annulment of the agent's

marriage to the principal or their legal separation, unless the

power of attorney otherwise provides; or

4. The power of attorney terminates.

C. Unless the power of attorney otherwise provides, an agent's

authority is exercisable until the authority terminates under

subsection B of this section, notwithstanding a lapse of time since

the execution of the power of attorney.

D. Termination of an agent's authority or of a power of

attorney is not effective as to the agent or another person that,

without actual knowledge of the termination, acts in good faith

under the power of attorney. An act so performed, unless otherwise

invalid or unenforceable, binds the principal and the principal's

successors in interest.

E. Incapacity of the principal of a power of attorney that is

not durable does not revoke or terminate the power of attorney as to

an agent or other person that, without actual knowledge of the

incapacity, acts in good faith under the power of attorney. An act

so performed, unless otherwise invalid or unenforceable, binds the

principal and the principal's successors in interest.

F. The execution of a power of attorney does not revoke a power

of attorney previously executed by the principal unless the

subsequent power of attorney provides that the previous power of

attorney is revoked or that all other powers of attorney are

revoked.
