A curator who is a non-resident, or who is about to leave the state permanently, shall execute a power of attorney appointing a resident of this state to receive service of process in any action brought against him in his capacity as curator; and may authorize this agent to represent him in all matters relating to the curatorship. A curator who is domiciled in the state and who will be absent temporarily therefrom may similarly appoint such an agent for either or both of these purposes. In all cases, the power of attorney shall be filed in the curatorship proceeding.
