A. Incapacity. As a general rule, each person has the authority to make decisions concerning himself or herself and no other person automatically has that authority. As long as a person has the capacity to make decisions, this rule for decision-making works. If a person becomes legally incapable of making decisions, however, the general rule does not work. In that case, authority to make decisions concerning the incapacitated person or his/her property must be transferred to another person.
