For example, compare the difference between giving the bank a copy of a power of attorney and letters of appointment for guardianship and conservatorship. Under the power of attorney, the bank will recognize your ability to act for the person. Without some form of clear evidence the person is incapacitated, though, the bank will also still follow the instructions of the person. By contrast, once the bank receives letters of conservatorship, the bank is now on notice that the person has no legal right to manage his or her own finances. Under this scenario, the difference between a power of attorney and a conservatorship can mean the difference between the person falling pray to financial exploitation.
