The legal requirement for the reading of banns only applies to the Church of England. [Marriage Act 1949, as amended by Church of England Marriage (Amendment) Measure 2012].
There used to be a similar legal requirement within the Church of Scotland but that was abolished by the Marriage (Scotland) Act 1977.
The Roman Catholic church was never covered by Parliamentary statute but, having first introduced the concept of reading banns in 1215, abolished the practice in 1983.
Methodists have never used the practice within their churches.
