"[A]s the term is generally understood, the practice of the law is the doing and performing services in a court of justice in any matter depending therein through its various stages and in conformity with the adopted rules of procedure.

(People v. Merchants Protective Corp. (1922) 189 Cal. 31, 535, quoting Eley v. Miller (1893) 7 Ind. App. 529 [emphasis added]).
