Who Signs a Power of Attorney?
The person granting the power of attorney (the principal) who appoints another to act as their agent is the person who must sign the power of attorney. In some cases, a form contains an option for the agent to sign to accept the appointment, but it is not required. The form should be notarized, but is not required to be witnessed. Therefore, a power of attorney from the owner spouse should be signed by that owner. Your signature would not be requited unless there is a clause for acceptance or notice by the agent.
