The legal term non compos mentis is Latin for “not of sound mind.” It is used in reference to someone who is mentally impaired to the extent that he or she cannot make rational decisions and therefore needs someone to make decisions on their behalf.
Modern Examples of Non Compos Mentis
In the modern age, this term has come to encompass a variety of mental health conditions, including dementia, schizophrenia, and mental retardation. Additionally, children, the elderly, and those suffering from substance abuse and addiction can be considered legally non compos mentis.
Consequences of Being Non Compos Mentis
When declared legally non compos mentis, a guardian or conservator will be appointed to make decisions on behalf of the individual. That guardian will handle all of the individual’s legal matters, including social security applications, medical care, housing, and other matters of legal importance.
