Jersey Legal French, also known as Jersey French, was the official dialect of French used administratively in Jersey. Since the anglicisation of the island, it survives as a written language for some laws, contracts, and other documents. Jersey's parliament, the States of Jersey, is part of the Assemblée parlementaire de la Francophonie. The use of the English language has been allowed in legislative debates since 2 February 1900; the current use of French in the States of Jersey is generally restricted to certain limited official state functions and formalities.
