California generally recognizes four different types of power of attorney, which are: General, Durable, Springing and Limited. A power of attorney (POA) refers to a legal document, which gives someone, called an “agent” or “attorney-in-fact,” the ability to act on behalf of or make property decisions or personal affairs decisions for someone else, called the “principal.” A power of attorney must meet California’s legal requirements to be valid. California requires the POA to be dated, be signed by the principal or in the principal’s name by another adult in the principal’s presence and at the principal’s direction, and be either notarized or signed by at least two witnesses
