Addressing Mental Capacity: Law, Pitfalls & Best Practices

Mental capacity in its basic form is the ability to make a decision and the loss thereof can happen to any one of us at any time. For the healthy, it may be the result of a sudden illness or injury. For older people, the onset of incapacity may be slower; the result of the progression of an illness such as Alzheimer's disease or just part of the normal aging process.

Understanding incapacity or capacity may seem as complex as the mind itself, but for the purposes of this article the following terms will carry their legal definitions as provided by Stroud's Judicial Dictionary of Words and Phrases. 6th ed. London: Sweet & Maxwell.

• "capacity": an ability or fitness to receive: In law it signifies when a man or body politick is able to give, or take lands, or other things, or to sue actions."
