A request to admit is a party’s formal written invitation to an opponent to admit specified facts or the authenticity of documents, to narrow the issues for trial and reduce costs. In practice, this is usually called a “notice to admit facts” or a “notice to admit documents/authenticity”. It is a procedural device used across civil litigation rather than a standalone statutory concept.Key features:- If the opponent admits, the fact or document need not be proved at trial, streamlining evidence and saving costs.- Unreasonable refusal to admit, where the point is later proved, can attract adverse costs orders.- Admissions are generally binding for the purposes of the proceedings, subject to the court’s discretion to permit withdrawal on terms.Jurisdictional usage:- England and Wales: governed by the Civil Procedure Rules (including CPR 32.18 for notices to admit facts and CPR 32.19 for document authenticity), with specified time limits before trial.- Scotland: Court of Session and Sheriff Court rules allow notices to admit facts or productions; admissions can limit proof and affect expenses.- Northern Ireland: similar mechanisms exist under the Rules of the Court of Judicature and County Court Rules.- Ireland: the Rules of the Superior Courts and Circuit Court Rules provide for notices to admit facts and documents, with comparable cost consequences.
