What makes a marriage legal in England and Wales?
A marriage is legally valid in England and Wales when both people are eligible to marry, notice has been given and the waiting period has passed, and the ceremony takes place at an approved location with the required officials and witnesses present and the marriage document correctly signed. Miss any one of these and the marriage is not legally recognised, however meaningful the day itself.
Eligibility comes first
You must both be at least 18, free to marry (not already married or in a civil partnership), and not within the prohibited degrees of relationship to each other. Both of you need to understand what marriage is and be entering it freely.
Notice and the waiting period
Civil preliminaries require each of you to give notice in person at the register office for the district where you live, after at least seven days' residence there. The standard wait is 28 days from the date notice is given before you can marry, though this is extended to 70 days if the Home Office refers your case under the immigration checking scheme.
Notice is valid for 12 months, so it must be given close enough to your ceremony date to still be valid, but early enough to clear the waiting period.
The ceremony itself
The ceremony must happen somewhere legally recognised for marriage — a register office, a venue approved by the local authority for civil ceremonies, or a religious building registered for marriage — with the right officials or authorised person present.
At the ceremony, you both make the legal declarations and contracting words, two witnesses are present, and the marriage document is signed. That signature, not the vows or rings, is what makes the marriage legally complete.
Religious marriage counts too
Marrying in a church, synagogue or other registered religious building can satisfy the legal requirements directly, without a separate civil ceremony, provided the building and officiant have the authority to register marriages. Some faiths use their own preliminaries, such as Church of England banns, instead of civil notice.
What this means for you
- A ceremony held before the notice period has passed is not a legal marriage, regardless of what was said or signed.
- If the venue or ceremony type changes materially after notice, you may need to give notice again.
- Two witnesses who understand what they are witnessing are a legal requirement, not a tradition.
