A living will allows a patient to specify their wishes for end-of-life care, while a durable power of attorney for healthcare allows them to appoint someone to make healthcare decisions on their behalf. A living will is only valid for a specific period of time, while a durable power of attorney for healthcare is valid until the patient revokes it. A living will can only be used in the event of a terminal illness, while a durable power of attorney for healthcare can be used in any situation where the patient is unable to make their own healthcare decisions.
