The person you appoint through a power of attorney to carry out personal business and financial wishes for your convenience, or if you are ever unconscious or unable to make your own decisions. Depending on how the power of attorney is structured, an attorney-in-fact may begin acting immediately or may only act upon your becoming incapacitated. An attorney-in-fact may have broad powers to handle all of your financial matters or may be allowed to act in only specific instances. Again, the power of attorney will determine how much authority is granted to the attorney-in-fact. While an attorney-in-fact does not need to have any specific qualifications to act, you should choose someone you trust and someone with whom you can talk about your financial affairs in advance of needing them to act on your behalf.
