Sharia Law Inheritance | What Every Muslim and Non-Muslim Expat Should Know?

Sharia law inheritance is one of those legal frameworks that decides how estates get divided in the UAE when there’s no valid registered will. It governs the estate split by default for Muslim residents and, historically, it also influenced non-Muslims. 

Since 2023, there’s been a separate civil law setup for non-Muslims, and then again there was another shift in 2026. Still, even with the changes, registered wills are really the only dependable way to make sure your assets end up how you actually want them to go.

Introduction  

A lot of expatriates in the UAE spend years building assets, property, shares in companies, savings and investments. But most people don’t really spend much time thinking about what happens if they die with no will. Sharia law inheritance is not a remote “local family only” idea; it’s live UAE law, and until fairly recently it could apply broadly, regardless of religion, to people living in the country. Then, in 2023, that changed, and later in 2026 it moved again. This overview sets out where the rules are today, what it means for Muslim and non-Muslim residents, and the real-world knock-on effects if you don’t plan.

What is the inheritance rule in Sharia law?  

Sharia law inheritance runs on a fixed heirship approach, meaning that certain relatives are assigned specific shares of the estate. The “math” is set by religious principle, not by your personal wishes, and it covers the whole estate for Muslims unless a will is used where it’s allowed, and within those limits. Those fixed shares generally work like this:

• A husband receives one-quarter of the estate if there are children, or one-half if there are no children  
• A wife receives one-eighth if there are children, or one-quarter if there are no children  
• Sons typically get double what daughters receive  
• Parents still receive fixed portions even if adult children exist  
• More distant relatives can receive a share if closer heirs are missing  

One major point, though, is that UAE law doesn’t run on joint ownership with right of survivorship in the way people sometimes expect. If property is held jointly, the surviving co-owner does not automatically just “take it over.” Instead, it gets treated as part of the estate, then divided using the fixed heir rules.

What is the one-third rule for Muslims?

Under Article 243 of Federal Decree-Law No. 28 of 2005 (Personal Status Law), a Muslim person can freely distribute up to one-third of their estate using a registered will. That portion can go to practically anyone, like charities, friends, or relatives not in the fixed heir list. The remaining two-thirds have to follow Sharia fixed shares no matter what.

But without a registered will, even that one-third of freedom basically disappears. In that case, the full estate is divided by the court according to the fixed allocations.

Does Sharia law apply to expats in Dubai?  

The answer was rewritten in 2023 and again in January 2026. Here’s the practical way it lands:

So, as of 2026, Sharia law does not automatically govern non-Muslim estates. After the implementation of Federal Decree-Law No. 41 of 2022, the UAE uses a dedicated civil law structure for non-Muslim expats. However, even if the final distribution rules changed, the timing issues can still show up: bank accounts are often frozen during probate for a while, while the court confirms heirs.

What happens when no will exists?  

Regardless of religion, dying in the UAE without a registered will tends to trigger a bunch of immediate, very practical problems like:

• Bank accounts, including joint accounts, are frozen until a court order is issued  
• Property transfers pause while heirship is verified  
• Business operations can slow down, especially if the company shares sit in the deceased’s name  
• Guardianship of minor children is decided by the court, not automatically by the surviving parent  
• A foreign will has to be translated, attested, and then submitted to UAE courts before it can really count, and that process can take months and cost more than a registered UAE will  

So yes, these outcomes show up for non-Muslims and Muslims alike. The civil law reforms affect how assets are ultimately distributed, but not how quickly courts move.

How can non-Muslims opt out?

Non-Muslim residents have several main pathways to register a UAE will, basically to override the default distribution approach:

• DIFC Wills Service Centre: runs under common law (DIFC Law No. 9 of 2020). It can cover UAE financial assets, real estate, free zone company shares, and guardianship of minor children. It’s open to all non-Muslims, no matter which emirate they live in.
  
• Abu Dhabi Judicial Department (ADJD): created under Abu Dhabi Law No. 14 of 2021. It uses both Arabic and English and is recognised across all emirates.
  
• Dubai Courts Notary Public: available for non-Muslims, in Arabic or a bilingual format. A practical option if someone wants a court-registered will without the DIFC structure.  

In general, a registered will under any of these routes overrides the default civil or Sharia distribution for the covered assets. The courts have to follow the will.

How does Arnifi help?

Inheritance doesn’t only mean personal cash. Company shares, investment portfolios, and UAE real estate are all inside the “inheritance pool”, and what happens depends a lot on how ownership is set up. 

Arnifi supports founders, investors, and expatriate families with DIFC and Abu Dhabi Civil Will preparation, plus corporate structuring that actually aligns with succession intentions, and asset holding arrangements so that ownership transfers the way you expect, instead of being routed through court defaults.

FAQs  

Q1. What is the inheritance rule in Sharia law?  

Fixed shares are allocated to specific relatives by law: spouse, children, and parents each get set portions, with sons usually receiving double what daughters receive.

Q2. Does Sharia law apply to expats in Dubai?  

For non-Muslims, a separate civil system has been used by default since 2023. No registered will; assets are still frozen during probate.

Q3. Can a Muslim opt out of Sharia inheritance in the UAE?  

Mostly, but not totally. A Muslim can distribute up to one-third of the estate freely, via a registered will. The remaining two-thirds still follow the standard Sharia shares.

Q4. What happens to a joint bank account when a spouse dies in the UAE?  

It gets frozen right away, no matter the surviving spouse’s nationality or religion, until a court order is issued.

Q5. Where can non-Muslims register a will in Dubai?  

Through the DIFC Wills Service Centre, the Abu Dhabi Judicial Department, or the Dubai Courts Notary Public.

Q6. Do company shares fall under inheritance rules in the UAE?  

Yes. Shares in mainland, free zone and DIFC companies are treated as part of the estate and distributed under the relevant inheritance rules.

Conclusion  

The 2023 and 2026 legal reforms made the UAE’s inheritance system a lot easier for non-Muslim expats to navigate. Fixed Sharia shares no longer apply automatically to non-Muslim estates, and registered civil wills now have full legal force across the seven emirates. 

What hasn’t really changed is the outcome when you don’t plan: frozen accounts, delayed probate, and assets being handled by courts instead of by your own wishes. A registered will is the one document that flips that result, and the sooner it’s ready, the lower the risk.
