Sharia inheritance and non-Muslim expats in the Gulf, explained

By Jamie Lee · Published 31 August 2026

"If I die in the Gulf, sharia decides who gets everything." Half true, and the half that's true is not the half most British expats think. The Gulf is six different legal systems: the UAE gave non-Muslims a civil inheritance regime in 2023, Qatar, Oman and Bahrain point to your national law, Kuwait applies sharia unless your heirs ask otherwise, and Saudi Arabia applies sharia to everyone. Here's the map, what sharia distribution actually looks like when it lands, and why a current English will matters in every one of the six.

There is a sentence you hear wherever British expats gather between Muscat and Manama: "out here, sharia law decides your estate." It gets repeated because it is short, frightening, and half true. The half that's true is not the half most people think, and the difference decides what happens to your family.

The Gulf holds six separate legal systems, and on the question of what happens to a non-Muslim foreigner's estate they give six different answers, from a civil inheritance code written for non-Muslims to sharia applied to everyone regardless of passport. British expats in the region tend to carry advice from the country they lived in before, which is how a family in Doha ends up planning around Dubai's rules and a family in Riyadh ends up assuming protections that stop at the Saudi border. So here is the map, drawn country by country, and then the part every country shares: why a current will under your own national law is the anchor everywhere, even where the local law is on your side.

What sharia distribution actually means

First, the rules themselves, stated factually. Sharia inheritance is a codified system of law, and it runs on fixed shares. A widow receives one eighth of her husband's estate if there are children, a quarter if there are none; a widower receives a quarter or a half. Parents generally take a sixth each where there are children. Sons take twice the share of daughters. Testamentary freedom is limited to one third of the estate, and under the classical rules a Muslim and a non-Muslim cannot inherit from each other. Guardianship of children is a separate question from custody, and the traditional default looks to male relatives, often on the father's side, rather than automatically to a surviving mother.

For a Muslim family these rules are a matter of faith with fourteen centuries of jurisprudence behind them. For a non-Muslim British family they usually produce a distribution nobody in the family would have chosen, which is why the question of when they apply to you matters so much.

A real example of what applying them looks like: in 2019, before the UAE's reforms, an Indian expat in Dubai lost his wife and found their joint accounts, holding around a million dirhams, frozen for five months. The couple had no UAE-recognised will, the courts applied sharia distribution, and the estate settled as the textbook shares dictate: half to their son, a quarter to their daughter, a quarter to him. Nothing irregular happened. The system worked exactly as designed; it just wasn't designed around his family.

The map, country by country

The UAE has moved furthest. Since February 2023, a federal civil personal status law has applied to non-Muslim residents: full testamentary freedom, and if you die without a will, a civil default of half to your spouse and the rest equally among your children regardless of gender. Your heirs can instead ask for your national law, and a registered will trumps the defaults. Alongside that sit the registration routes British expats in the Emirates know well: wills registered through the DIFC in Dubai for non-Muslims, and through the Abu Dhabi judicial department for Abu Dhabi. One trap survives the reforms and is written into the UAE's own civil code: wills made by foreigners over real property in the UAE are governed by UAE law, so if you own an Emirates apartment, take specific advice rather than assuming your English will reaches it.

Qatar, Oman and Bahrain answer the question with conflict-of-laws rules. Qatar's civil code applies the law of the deceased's nationality to inheritance and wills; Oman's civil transactions law says the same, and Omani practitioners report that courts do not usually apply sharia principles to non-Muslims; Bahrain has run non-Muslim foreigners' estates under their home-country law through its civil courts since 1971, and UK government guidance confirms it plainly. For a Briton in any of the three, that means English law, and the will made under it.

Kuwait has the same idea on the books with the opposite default in practice: local guidance is consistent that sharia distribution applies unless the heirs expressly ask the court to apply the deceased's national law, with heavily attested home-country documents. Your family would have to know to ask, in Arabic, through a Kuwaiti court, while grieving. That is a thin thread to hang an estate on.

Saudi Arabia is the outlier. Sharia is the law of the land for succession, codified since 2022, and the Saudi courts rule on any assets in the Kingdom whatever the deceased's nationality or religion. There is no civil regime for non-Muslims, and although UK government guidance says a non-Muslim's national law may apply, that is not a gateway to rely on. Practitioners' consistent advice is to plan around it: keep what you can outside the Kingdom, hold a current English will for everything beyond Saudi borders, and treat anything you keep in-Kingdom as subject to local process.

Two caveats run across the whole map. Even where the local code points to your national law, that foreign law has to be pleaded and proven, in Arabic, with legalised documents, before a local court; commentary on the region notes that in practice it is invoked far more often than it is smoothly applied. And every one of these codes carries a public-order exception that lets a court decline to apply foreign law it finds incompatible with local principles. The law on the books is the start of the story, not the end.

The part that catches everyone, whatever the law says

Here is what the six systems share. Bank accounts freeze on death, joint accounts included; across the region there is no survivorship on a joint account, and the survivor cannot draw their "own" half until a court order says so. With a locally registered or readily enforceable will, practitioners talk in months; without one, in years. Final salary and end-of-service gratuity are generally paid through official channels to your legal heirs, which means they wait on the same court process. And if both parents die, the courts decide who the children go to, applying defaults that a will with named guardians can inform but never entirely displace.

The paperwork burden splits the region in two. Saudi Arabia, Bahrain and Oman are members of the apostille convention, so UK documents need a single FCDO apostille. The UAE, Qatar and Kuwait are not, so every UK document runs the full consular chain: UK certification, then the relevant embassy in London, then the local foreign ministry, plus certified Arabic translation at each destination. Slow either way; much slower unprepared.

One reassurance, and one correction to it. No Gulf state levies inheritance tax. But British expats are rarely outside UK inheritance tax just by being in the Gulf: the long-term residence rules keep your worldwide estate in scope if you were UK-resident in 10 of the last 20 tax years or are still inside the tail that follows leaving, your UK assets stay in scope regardless, and from April 2027 unused pensions join the estate. A Gulf posting is often the fastest-accumulating stretch of a working life; it is not a tax holiday from planning.

What to do now

Place yourself on the map. Which country you're in decides whether your estate runs on a civil code, your national law, an heir's petition, or sharia. Advice imported from a previous posting is the region's most common planning error.
Make or update the English will. In Qatar, Oman, Bahrain and Kuwait it is the document your national law works through; in the UAE it anchors everything outside the registration systems; in Saudi Arabia it governs everything you hold outside the Kingdom.
In the UAE, consider registering locally too, through the DIFC or Abu Dhabi routes, and take specific advice on any UAE real estate, which UAE law treats as its own.
Name guardians, temporary and local as well as permanent and British, and tell both sets of people.
Keep accessible money in each spouse's sole name, enough to run the household for months. The freeze is universal and joint accounts do not escape it.
Build the file while you're alive: legalised or apostilled copies of the will, marriage and birth certificates, an asset list, and your employer's HR contact for the gratuity.

An Expat Legacy will is drafted under the law of England and Wales around expat circumstances, guardianship nominations included, and reviewed by a person before your documents are released: £149 for a single will, £249 for mirror wills for a couple. Wherever in the Gulf you are, your family will be better placed with a current English will than without one. That is true in all six countries.

Expat Legacy provides England and Wales wills and general information about cross-border estate planning. This is general information, not legal or tax advice for your circumstances; Gulf legal procedures change and vary by emirate and by court, tax treatment depends on individual circumstances, and for local property, business interests or disputes you should engage a lawyer in the country concerned.

Common questions

How does Sharia law affect inheritance for non-muslims in the Gulf?

In countries like Saudi Arabia, sharia distribution applies to all estates regardless of the deceased person's religion. This system uses fixed shares where a widow may receive only one eighth or one quarter of the estate, and sons receive twice the share of daughters. For non-Muslims, these rules often result in a distribution of assets that the family would not have chosen for themselves.

Will my bank account be frozen if I die in the Gulf?

Yes, across the Gulf region, bank accounts are frozen upon death, and this includes joint accounts. There is no right of survivorship, meaning a surviving spouse cannot access the funds until a court order is issued. Without a registered or enforceable will to guide the court, this process can take years rather than months.

Does a British will work in the UAE and Middle East?

A current English will is an essential anchor for British expats because many Gulf countries, such as Qatar, Oman, and Bahrain, use the law of the deceased's nationality for inheritance. In the UAE, a registered will can trump the civil default rules, though specific advice is needed for local real estate. Even where national law is accepted, your family must still prove that law in a local court using legalised Arabic documents.
