This article examines garnishee proceedings as a means of enforcing monetary judgments under Nigerian law. It employs a doctrinal and non-doctrinal research methodology through the usage of statutes, judicial Authorities, online Journals and articles to arrive at its conclusion. The article examines the doctrines of functus officio and loss of jurisdiction upon the entry of an appeal, and the continued authority of trial courts to entertain garnishee proceedings. Relying on the Sheriffs and Civil Process Act, the Judgment (Enforcement) Rules, the Court of Appeal Rules, and relevant judicial decisions, the article shows that garnishee proceedings are sui generis and procedurally independent of the substantive action that resulted in judgment.
