Financial capacity is the ability to manage financial affairs on one's own, consistent with a person's own best interest. When financial capacity is diminished (less than what is usual), a trusted family member, friend, or representative can assist in financial decision making. It is important for people to consider their choice of agent (the person who is appointed to assist or take over financial decision making) very carefully to avoid misuse, deception, fraud, or theft. Major decisions, like selecting an agent, are best made in advance, while a person is of sound mind. The February 16, 2011, issue of JAMA includes an article about financial capacity in older adults with cognitive impairment.
