Next Friend

Next friend, in British law and American law, is the phrase used for a person who represents in an action another person who is under disability or otherwise unable to maintain a suit on their own behalf as a result of their circumstances, who does not have a legal guardian.This disability often arises from infancy, mental incapacity, or lack of access to counsel, consequently every application to the court on behalf of an infant or a lunatic or a person detained without access to an attorney, who does not have a legal guardian or someone authorized to act on their behalf with a power of attorney, must be made through a next friend (prochein amy, proximus amicus).
