A Durable Power of Attorney is a legal document that enables the grantor (Principal) to designate another person called the agent or attorney-in-fact to act on behalf of the Principal, even in the event the individual becomes disabled or incapacitated. Therefore a “durable” power of attorney stays valid even if the Principal is not able to handle his or her affairs (incapacitated). Usually a power of attorney becomes ineffective if its grantor dies or becomes incapacitated. If the grantor does not specify that that the power of attorney is to be durable, it will automatically end when the principal becomes incapacitated.
