Careful with do-it-yourself lawyering, though. Medical and other “durable” powers of attorney must conform to a specific statutory form. Generally, and agent can only do what the principal can do, so your agent’s authority to act ends the moment you become incapacitated unless the POA satisfies the statute.
And, it cannot be overstated to ONLY grant a POA to someone or those who can be trusted to act according to your final wishes!!
