Unauthorized practice of law
Unauthorized practice of law. The doctrine bars nonlawyers from representing others or giving specific legal advice; parties may represent themselves or be represented by counsel (28 U.S.C. § 1654). Lawyers may seek pro hac vice admission for a case. State limits yield to federal authorization, as in Sperry’s approval of nonlawyer patent agents before the USPTO.
Rule to remember
Unauthorized practice of law is providing legal services for another—such as court representation, individualized legal advice, or drafting legal instruments requiring legal judgment—without a law license or other authorization in that jurisdiction.
Key elements and checks
- Acts involve legal services for another person or entity.
- No license or other jurisdictional authorization (e.g., admission) to provide those services.
- Core reserved functions include: (a) representing another in court; (b) giving individualized legal advice; (c) drafting/selecting instruments requiring legal judgment.
- Self-representation is permitted; one may proceed pro se but not represent others.
- Exceptions/safe harbors include court permission to appear pro hac vice and federally authorized practice before certain agencies (e.g., registered patent agents before the USPTO).
- Meaningful state variation: each state defines and enforces what counts as “practice of law,” so specific applications and penalties differ.
