scrivener

Definition from Nolo’s Plain-English Law Dictionary

A person who writes a document for another, usually for a fee. If a lawyer merely writes out the terms of a lease or contract exactly as requested by the client, without giving legal advice, then the lawyer is just a scrivener and is probably not responsible for legal errors (unless they were so obvious as to warrant comment). A nonlawyer may act as a scrivener without getting in trouble for practicing law without a license.
