Is a Nikah legally binding in the UK?

What makes a Nikah legal in England and Wales

For your Nikah to be your legal marriage, all of these must happen:

• You both give notice of your marriage at your local register office, at least 29 days before the wedding. If either of you is subject to immigration control, the notice period can be longer.
• The Nikah takes place in a mosque or other religious building that is registered for marriages.
• An authorised person, usually appointed by the mosque, or a registrar is there to register the marriage.
• You both say the legal words of marriage in front of them and two witnesses.

Afterwards you, your witnesses and the authorised person or registrar sign the marriage schedule, so the marriage can be registered.

If the notice, the registered building or the authorised person or registrar is missing, your Nikah will not usually be a legal marriage. Not every mosque is registered for marriages, and not every registered mosque has an authorised person, so ask yours early. If there is no authorised person, you can book a registrar to attend, usually for a fee.

What if our Nikah is not registered?

A Nikah that does not meet these rules does not create a legal marriage. In 2020 the Court of Appeal held that a Nikah held without the legal formalities is a non-qualifying ceremony, which means that in law you are not married at all.

That matters most when something goes wrong:

• If you separate, neither of you can ask the family court for a share of the home, savings or pensions in the way a husband or wife can.
• If one of you dies without a will, the other does not automatically inherit.
• It can also affect tax, pensions and visa applications.

A Nikah held outside the rules cannot be registered afterwards. To become legally married, you would need to marry again in law, usually with a civil ceremony.

Whether a Nikah is valid in Islam is a separate question from whether it is a legal marriage. Many couples want both, and arrange both.

How to make your marriage legal

There are two ways to do it.

A civil ceremony as well as your Nikah

Give notice, then marry at a register office or at a venue approved for civil ceremonies. Your Nikah can be before or after it, on the same day or another day, wherever you choose.

A civil ceremony cannot include any religious content, so your Nikah has to be kept separate from it. If you want both at the same venue, ask the venue and the register office how they need to be separated.

A Nikah at a mosque registered for marriages

If your mosque is registered for marriages and an authorised person or a registrar is present, one ceremony can be both your Nikah and your legal marriage. You still give notice at the register office first.

A Nikah at home, or at a hall or hotel that is not a registered place of worship, cannot be your legal marriage on its own.

Scotland and Northern Ireland

The law is different outside England and Wales. In Scotland and in Northern Ireland, a religious ceremony can be a legal marriage when the person leading it is authorised to conduct marriages there and you have given notice to the registrar in advance. Check the details with the registrar where you plan to marry, and with your imam.

Is the law changing?

It might. In 2022 the Law Commission recommended that the law should regulate who conducts a wedding rather than the building it takes place in. In July 2026 the Ministry of Justice consulted on reforms along those lines, and the consultation looked directly at religious-only marriages, including the Nikah. It closed on 24 September 2026.

Nothing has changed yet. The current rules apply until new legislation is passed, and there is no date for that.

Questions to ask your mosque or imam

• Is the mosque registered for marriages?
• Is there an authorised person, or do we need to book a registrar?
• What do you need from us before the Nikah?
• Will our Nikah be registered as a legal marriage, or do we need a civil ceremony as well?

Questions couples ask

Can we have our Nikah and civil ceremony on the same day?

Yes. Some couples marry at the register office and hold their Nikah at a mosque or venue later the same day. Give notice in good time, because it has to be at least 29 days before the civil ceremony.

Is a Nikah certificate a legal document?

A Nikah certificate from a mosque or imam records your religious marriage. It is not a legal marriage certificate. If your marriage was registered, your marriage certificate comes from the register office.

We have already had our Nikah. Can we make it legal now?

Yes, by having a civil ceremony. It cannot be backdated: in law, your marriage starts on the day of the civil ceremony.
