Tens of thousands of wealthy people have moved to the UAE in the past few years, drawn by zero income tax, safety and stability. Almost all of them have answered the question of how to make and hold money here. Far fewer have answered a more consequential one: once the wealth is in the country, how do you protect it and pass it on to the next generation? The UAE has quietly built sophisticated, onshore answers to that question. The most dangerous mistake a wealthy resident can make is not knowing they exist.
The default that catches people out
Here is the trap. Under UAE law, in the absence of a registered will, the assets of a person who dies in the country can default to Sharia inheritance principles, regardless of the deceased’s nationality or religion. For a non-Muslim expatriate, that can mean fixed shares distributed in a way that bears no relation to their actual wishes. And it gets more practical than that. Without a valid will or a holding structure in place, banks and authorities can freeze the deceased’s assets on death, and the family then needs a court order to release them, a process that can stretch from months into years at exactly the moment a family can least absorb the delay.
The reform that changed the picture
The UAE recognised this was incompatible with its ambition to be a long-term home for internationally mobile families, and it acted. Federal Decree-Law No. 41 of 2022 on Civil Personal Status, in force from 2023, means Sharia principles no longer apply by default to non-Muslims who die without a will, and non-Muslims, both residents and nationals, can elect to have their home country’s law govern their estate. Abu Dhabi and Dubai have layered their own non-Muslim personal status frameworks on top, with Dubai Law No. 2 of 2025 further reshaping non-Muslim inheritance and the use of foundations. The direction is unmistakable: the UAE is deliberately building a parallel, common-law-flavoured succession system for its international residents.
The tools that system provides fall into three layers.
Tool one: the registered will, which is the floor
The single most common and most dangerous gap that advisers report in wealthy expatriate clients is the absence of a registered UAE will. A will registered through the DIFC or ADGM, or through the Abu Dhabi Judicial Department registry, overrides the default Sharia distribution for the assets it covers. It is drafted in English under common-law principles and enforceable through the DIFC or ADGM courts, which feel familiar to anyone used to a Western legal system.
The options are flexible. A full will can cover worldwide assets, while more targeted and lower-cost wills cover up to five UAE properties, ownership in UAE companies, UAE bank accounts, or simply the guardianship of minor children. For any non-Muslim resident with UAE assets or children, a registered will is the single most important estate-planning document, and it is remarkable how many otherwise sophisticated people do not have one.
Tool two: the foundation, where succession becomes structural
A foundation is where planning moves from a document to an architecture. It is a separate legal entity with its own legal personality and no shareholders, an orphan structure in which no individual directly owns the assets, managed by a council according to rules the founder sets in advance. Foundations are available in the DIFC, ADGM and RAK ICC, and setup is quick, typically two to six weeks.
The mechanics are simple to describe and powerful in effect. You transfer company shares, real estate or investment portfolios into the foundation and define how they are held and distributed, during your lifetime and after. Because it sidesteps probate, there is no freeze and no court-order delay when the founder dies. It ring-fences assets from personal liabilities and disputes, keeps ownership private, mitigates forced-heirship claims from other jurisdictions, and continues seamlessly across generations, especially when paired with a family constitution and a letter of wishes. Because a foundation has its own legal personality, unlike a trust, it is clean and practical for holding UAE real estate and company shares and dealing with local registries.
There is a tax dimension too. Under Article 17 of the UAE Corporate Tax Law, a family foundation can apply to the Federal Tax Authority to be treated as fiscally transparent, an unincorporated partnership, so it is not taxed as a separate entity and income flows through to beneficiaries. Approval is not automatic, and the foundation must stick to passive asset management rather than running an active business, or it risks being taxed as a company.
Tool three: trusts, and the offshore-to-onshore shift
The DIFC and ADGM also operate mature common-law trust regimes modelled on jurisdictions like Jersey and the Cayman Islands, and a federal trust law exists outside the free zones, though it is newer and less tested. The larger trend worth noting is that high-net-worth families are increasingly re-domiciling structures out of traditional offshore centres like the British Virgin Islands and Cayman and into the DIFC and ADGM, drawn by legal certainty, reputational advantages, English common-law courts, and judgments that are widely recognised abroad. The UAE now competes directly with Switzerland and Singapore for this work.
The decision framework
Think of these tools as layers rather than alternatives. Everyone with UAE assets or children needs a registered will. That is the floor, and it is non-negotiable. Families with significant or cross-border holdings add a foundation for governance, privacy, probate avoidance and multi-generational control. Trusts fit specific cases, particularly for certain beneficiary-protection needs. In practice, most expatriate families combine a will, which decides who inherits, with a foundation, which ensures the assets stay managed exactly as intended. The right combination depends on asset composition, the jurisdictions involved, and the family’s objectives, and getting that match wrong is where families actually get hurt.
The honest caveat
None of this is a magic tax shield, and it would be irresponsible to present it as one. Even for a UAE resident, overseas assets and personal connections, things like domicile, citizenship, and where an asset physically sits, can trigger foreign estate or inheritance tax regimes, and documents drafted in different countries can conflict with one another. Serious planning uses a jurisdiction-by-jurisdiction map of what you own, where it sits, and which law governs it, built with qualified counsel. This article is general information, not legal or tax advice, and any structuring should be done with a licensed adviser who knows your full picture.
The takeaway
The UAE has matured from a place where you accumulate wealth into a place where you can also protect it and pass it on, using world-class, onshore, common-law tools that did not properly exist a few years ago. But the architecture only works if you use it. Many of the wealthy families who moved here for the tax and the stability have left the most basic protection undone, a registered will and a clear holding structure, on the quiet assumption that a safe, stable country means their wealth will pass on safely and smoothly by default. In the UAE, by default, it does not. By design, it now can. The gap between those two words is worth exactly as much as your estate.
