Pro se legal representation in the United States

Pro se legal representation (/ˌpr ˈs/ or /ˌpr ˈs/) comes from Latin pro se, meaning "for oneself" or "on behalf of themselves", which in modern law means to argue on one's own behalf in a legal proceeding as a defendant or plaintiff in civil cases or a defendant in criminal cases.

This status is sometimes known as propria persona (abbreviated to "pro per"). In England and Wales the comparable status is that of "litigant in person".
