A Latin term meaning "for this occasion" that refers to a lawyer who is temporarily admitted to practice law in a jurisdiction or court only for a particular case, so that the lawyer may appear in the case without being formally admitted to practice law in the jurisdiction or court where the case is pending.

For example, a New York lawyer who wishes to represent a client in a California federal case may become admitted pro hac vice in that case, instead of becoming formally admitted in the California federal court.
