Do all agents and successor agents need to sign and notarize a power of attorney in New York?

In New York, a power of attorney (POA) must be signed by the principal (the person granting authority) and acknowledged before a notary public. However, agents (the individuals receiving authority) do not need to sign or notarize the POA for it to be valid. Successor agents, designated to act if the primary agent is unavailable, also do not need to sign the document. It is essential for the principal to ensure the POA document is properly executed to be effective.
