{{One source|date=May 2024}} '''Relator''' {{IPAc-en|r|ᵻ|ˈ|l|eɪ|t|ər}}, female '''relatrix''' {{IPAc-en|r|ᵻ|ˈ|l|eɪ|t|r|ɪ|k|s}}, (Latin for "narrator") is the legal term meaning a private person at whose relation or on whose behalf an application for a [[quo warranto]] or [[mandamus]] is filed.<ref>A Dictionary of Modern Legal Usage. Copyright (c) 1990 Bryan A. Garner, [[Oxford University Press]], Inc.</ref> The relator appears as one beneficially interested, but the action is maintained on his behalf. The relator furnishes the knowledge or facts on which [[an information]] or a [[proceeding in quo warranto]] is based. Such a proceeding is usually in the name of the state, [[ex rel]]. (''ex relatione'' = "[arising] out of the narration") of the relator, and so is called an "[[ex rel]]. action".
==Qui tam== A [[qui tam]] (in the name of the king) action may be brought by any party (as a relator) against an entity that is fraudulently collecting money from the United States government by filing false claims. The party bringing the suit – the relator – must have possession of information substantiating the claim of fraud against the government. The government shares a percentage of the monies collected, along with a share of treble damages and penalties if any, with the relator. The relator may be any entity including a private individual, trade association, or labor union. Congress authorized qui tam actions in the [[False Claims Act]].
==Pro Se== Qui Tam is related to [[pro se]] (for self) and as such this should be considered in light of qui tam.
