From The Celtic Language News:
Steph Norman and Aaron Willoughby have been told they must have their wedding ceremony in English first. Steph Norman and Aaron Willoughby were told by Cornwall Council their ceremony must be in English and Cornish. The council said "declaratory and contracting words" can only be said in English or Welsh for a legally binding marriage. Ms Norman said "I feel if everyone understands the language, it should be up to them what language they speak". The couple contacted the council as part of their search for a registrar who speaks Cornish, when they were told their plans for the ceremony were not legal. Ms Norman, 32, from St Anne near St Day, then researched the Marriage Act 1949 and found an exception only applied to Welsh speakers.
