A general power of attorney is a document that gives your agent a broad authority in handling your affairs. In the power of attorney, especially for the durable one, that same agent is given the full authority to manage and handle all your money and assets in case you get mentally incapacitated. That is why many people choose to appoint their spouses or relatives as agents. But there are still issues and conflicts arising in such situations. If nobody has powers of attorney to act on your behalf and you are already unconscious or mentally incapable, the courts will assign someone to make health care decisions for you. The second type of durable powers of attorney is financial in nature. It is defined as the full legal authority given to another individual to be responsible for all your finance-related affairs, including filing income tax returns and paying the bills.

Your agent should also formally receive a copy of that revocation. As for the durable power of attorney, you could do two actions. First, you could get into a new durable power of attorney to name a new person as your attorney-in-fact or agent.
