Before you can marry or join in civil partnership, you must complete the legal formalities and give notice of your intention.
A Notice of Marriage or Notice of Civil Partnership is a legal document showing the two people getting married or registering a civil partnership and the venue where their ceremony will take place.
You must both give notice of your intention at a Register Office in the district you live. If you and your partner live in different areas, you will each need to give notice in your own registration district. If you or your partner are subject to immigration control you must both give notice together in the district in which one or both of you live.
Note, you cannot give notice to marry or enter in to a marriage ceremony if you're under 18.
