Marriage and the law

Nikah-only marriage and your rights

A contract recognised in Islam, but often not in English law. What the scholarship says, what the research shows, and what couples can do about it.

In short

A nikah held in England or Wales that is not legally registered is usually not a marriage in English law. If the relationship ends, a spouse, most often the wife, may have no right to a share of the other’s property or pension, or to maintenance for herself. Registering the marriage, or putting written agreements and wills in place, reduces that risk.

General information for England and Wales, not advice on your situation. The law and its application can change.

In Islam, the nikah is not a formality. It is the contract that makes a man and woman husband and wife, that makes intimacy lawful, and that establishes rights and duties between them before God. For a British Muslim couple, it is the real marriage. And yet, in the eyes of English law, that same marriage may not exist at all.

This gap affects many Muslims in Britain. A couple can be married in their religion and, at the same time, be treated in English law as not married. The consequences of that gap fall, more often than not, on women, and they usually surface at the worst possible moment.

The Islamic basis

وَمِنْ آيَاتِهِ أَنْ خَلَقَ لَكُم مِّنْ أَنفُسِكُمْ أَزْوَاجًا لِّتَسْكُنُوا إِلَيْهَا وَجَعَلَ بَيْنَكُم مَّوَدَّةً وَرَحْمَةً

“And among His signs is that He created for you mates from among yourselves, that you may find tranquillity in them; and He placed between you affection and mercy.”

Qur’an, Surah ar-Rum (30:21)

Marriage in Islam is a covenant of tranquillity, affection and mercy, and the nikah is how that covenant is entered. It is precisely because the nikah carries such weight that so many couples treat it as sufficient in itself. The civil registration can feel like paperwork; the nikah feels like the marriage. That instinct is understandable. It is also, in Britain, a legal risk.

01 · The lawWhy a nikah alone is not a marriage in English law

English law does not recognise a religious ceremony as a legal marriage unless it meets specific civil requirements: broadly, that it takes place in a registered building or is otherwise civilly registered. A nikah held in a private home, or at a mosque not registered for marriages, generally falls outside legal recognition.

The courts have a term for this outcome: a non-marriage, or non-qualifying ceremony. The couple are treated as cohabitants. And here the second myth compounds the first: there is no such thing as common-law marriage in England and Wales, however many years a couple live together or how many children they raise.

Married in the sight of God. Cohabiting in the sight of the law.

02 · The researchWhat the studies actually show

This is not anecdote. It is one of the most studied questions in British family law. Dr Rajnaara Akhtar, whose work appears in the Oxford Journal of Law and Religion, has documented how religious-only marriage has become increasingly common, and why.

Her research, and that of scholars including Rebecca Probert, Samia Bano and others, finds that many couples see no incentive to register, viewing the civil ceremony as adding nothing to a marriage their community already recognises. But awareness is the deeper problem.

Islamic principle

The nikah is the marriage. Cohabitation outside it is impermissible, so the nikah is entered first and foremost to make the relationship lawful.

The research

Around 28% of people in unregistered marriages did not realise their ceremony was not legally recognised (Akhtar).

The law

An unregistered nikah is a non-marriage; the civil courts have no power to divide assets or grant a divorce.

That 28% figure is the heart of the matter. A significant share of couples are not making an informed choice to forgo legal protection. Many do not know it is missing, and assume, as many people in Britain do, that living together gives legal rights. In general, it does not.

03 · The costWhy this falls hardest on women

When a religious-only relationship ends, in separation or bereavement, the unregistered spouse discovers what the law does, and does not, provide. In practice she may find that she:

The review that named it

The 2018 independent review into the application of sharia law in England and Wales found precisely this pattern, and recommended that Islamic marriages be civilly registered alongside the religious ceremony, so that Muslim women are not left without the protection the law affords everyone else.

04 · The remedyHow to keep the nikah, and gain the protection

None of this asks anyone to value the nikah less. The point is the opposite: to let the nikah stand as the marriage it is, while ensuring the law recognises it too. There are two clear routes.

Register the marriage civilly

The most complete protection is a civil marriage alongside, or after, the nikah, at a register office or a mosque licensed for legal marriages. It is usually quick and inexpensive, and it gives both spouses the legal rights of a married couple. If the nikah has already taken place, you can still marry legally now, at a register office or a registered mosque (this creates a legal marriage from that date; it does not back-date the nikah).

Or protect yourself another way

Where a couple choose, for their own reasons, not to register, protections can still be put in place: a clear record of the mahr, a valid Islamic will so the estate passes by faraid, a cohabitation agreement, and a declaration of trust over jointly-owned property.

Do it right in your religion, and let the law recognise it too.

Reform may be coming. The government has committed to modernising weddings law, which could in time allow Muslim ceremonies to be legally binding in their own right. But it is not yet law, and the proposals may change before they are. If you are unsure whether your nikah is recognised, the surest step is to find out.

Common questions

Is a nikah legally recognised in the UK?
A nikah performed in England or Wales is generally not recognised in law unless the marriage is also civilly registered. Otherwise the couple are treated as cohabitants and the marriage as a non-marriage.
Can I get a UK divorce if I only had a nikah?
Usually not. A nikah held in England or Wales that was never registered is usually treated as a non-qualifying ceremony, so the courts cannot grant a civil divorce or make financial orders. A nikah conducted and validly registered abroad may be recognised.
What did the research find?
Studies by Dr Rajnaara Akhtar and others found many couples see no incentive to register, and around 28% of those in unregistered marriages did not realise their ceremony was not legally recognised.
