If you are both British nationals living abroad, or if you are both British nationals but just one of you lives abroad, you can apply for a Common Licence to marry in a Church of England church on the basis of having one of seven legally-recognised connections with it.

The Vicar of the church will help you with the Common Licence application so you need to contact them first.
