Although the authority granted in a Power of Attorney is well established by law, it is not uncommon for a third party to refuse to honor that authority nonetheless. A common reason for refusing to honor an Agent’s authority is claiming that the POA was executed too long ago. A third party may also question the authenticity of the document or refuse to honor a POA unless it is created using their form. Enacted in 2017, the California Durable Power of Attorney Law dictates that when a POA is presented to a third-party that third-party now has three choices – to accept it, to request that the agent sign a certificate, or to request the agent provide an opinion of counsel. The new law also imposes time periods within a third part must act and sets forth 11 reasons why a third-party can refuse to honor an Agent’s authority. If the third party does refuse using one of those 11 reasons, it is required to give the Agent a written Private Reason Affidavit, which is signed under penalty of perjury.
