Section 705.05 - Designation and powers of agent(1) A party to an account, notwithstanding such party's minority, or if the account has multiple parties, all of them acting in concert, may appoint one or more agents for purposes of making withdrawals from the account. The authority of an agent to make withdrawals from an account may be terminated by any party to the account upon written notice to the financial institution, and this shall not preclude a party's liability for wrongful termination of such agency.(2) The uses and purposes for which withdrawals may be made by an agent to an account shall be governed by agency principles of general application. The application of any sum withdrawn from an account shall only be subject to inquiry by a party to the account, and such party shall have the burden of proving breach of the agency relationship. A minor party may not disaffirm the appointment of an agent, but the period within which the minor party may inquire into the propriety of any withdrawal shall be governed by s. 893.16 or 893.18. Unless there is clear and convincing evidence of a different intent, if the agent is a spouse of a party, the sums so withdrawn may be used, but not by way of limitation, for the support and maintenance of either spouse or any common minor children.(3) The parties to an account may provide, by the terms of the account or by independent written power of attorney which, if later, shall have precedence over the terms of the account, that the authority conferred upon an agent shall be exercisable notwithstanding any party's legal disability. In such case the authority of the agent is also exercisable notwithstanding later uncertainty as to whether a party is dead or alive. Absent a written direction to the contrary, the foregoing power of withdrawal shall exist without the necessity of written provision if the agent is the spouse of a party, but in such a case funds so withdrawn, the application of which may be inquired into only as provided in sub. (2), may only be used for the support and maintenance of either spouse and any common minor children. This subsection shall apply to all accounts created prior to and after July 1, 1975.1973 c. 291; 1979 c. 323 s. 33; 1993 a. 486.
