Gulf-based expats typically hold assets across multiple jurisdictions - property in their home country, investment accounts in a third country, and savings or business interests in the GCC - which means a single will or estate plan is rarely sufficient. When a resident dies intestate or without a valid cross-border plan, the laws of each jurisdiction where assets are held will apply independently, and those laws do not always align. This guide outlines the structural considerations expats in the UAE, Saudi Arabia, Qatar, Bahrain, Kuwait, and Oman should understand before engaging a qualified cross-border legal and tax adviser.
Key takeaways
- -Assets held in different countries are generally governed by the laws of those countries at the time of death - a will valid in one jurisdiction may not be recognised in another.
- -GCC countries apply their own inheritance frameworks, which may differ significantly from the laws of an expat's home country. Non-Muslim expats in several GCC states can register wills that direct the application of their home-country law to their locally held assets.
- -Certain home-country tax obligations - such as UK inheritance tax or US estate tax - can follow an expat regardless of where they are resident at the time of death, depending on domicile or citizenship rules.
- -Cross-border estate planning requires a coordinated team: a local GCC legal specialist, a home-country estate lawyer, and a qualified tax adviser familiar with any relevant double-tax or estate-tax treaties.
Why Cross-Border Planning Matters for Gulf Expats
An expat living in Dubai, Riyadh, or Doha rarely holds all their wealth in one place. It is common to maintain a family home in the UK, Ireland, Canada, or Australia; brokerage accounts in the US or Europe; and simultaneously accumulate savings, property, or business equity in a GCC country. Each of those asset locations is subject to the succession and tax laws of its own jurisdiction, and those frameworks operate independently of one another.
In the absence of a structured estate plan, the distribution of assets after death defaults to whatever legal framework each jurisdiction applies by default. In the GCC, that default framework is Sharia-based succession law for Muslim residents. Several GCC states have created specific mechanisms allowing non-Muslim expats to register wills that direct courts to apply their home-country law instead. Without such a registration, the default framework applies regardless of any informal wishes expressed by the deceased.
The practical consequences of failing to plan include delays in releasing assets, potential for conflicting court orders across jurisdictions, and the risk that assets pass to beneficiaries in proportions that do not reflect the deceased's wishes. These are not hypothetical risks - they are documented outcomes that cross-border legal practitioners encounter regularly. Consult a qualified cross-border estate lawyer before assuming any existing arrangement is sufficient.
Succession Frameworks Across the GCC
Each GCC state has its own legal framework governing inheritance. In the UAE, Federal Law No. 28 of 2005 (the Personal Status Law) applies Sharia succession principles by default to all residents, including non-Muslims, unless a will has been registered directing courts to apply a different law. The UAE introduced specific provisions allowing non-Muslim expats to register wills at the Dubai International Financial Centre (DIFC) Wills Service Centre or through the Abu Dhabi Judicial Department, directing the application of their home-country law to UAE-situated assets. Expats should verify current registration procedures and eligibility directly with those bodies.
In Saudi Arabia, succession is governed by Islamic law as interpreted by the Kingdom's courts. Non-Muslim residents should seek specialist legal advice regarding how their locally held assets would be treated and what, if any, mechanisms exist for directing an alternative framework. The Ministry of Justice in Saudi Arabia is the relevant authority for questions on succession registration.
Qatar, Bahrain, Kuwait, and Oman each have their own personal status and succession laws grounded in Islamic jurisprudence, with varying provisions for non-Muslim expatriates. The degree to which foreign nationals can direct the application of a different law varies by jurisdiction. Expats should consult a local legal specialist in each GCC country where they hold significant assets, rather than assuming that an arrangement valid in one GCC state carries over to another.
One practical step relevant across most GCC jurisdictions is ensuring that locally held financial accounts have clearly documented beneficiary designations or joint ownership arrangements where permitted by local law and the relevant financial institution. However, whether such designations override succession law in a given jurisdiction is a question for a local lawyer, not a general guide.
Home-Country Tax Obligations That Follow You Abroad
Residency in a GCC country does not automatically extinguish an expat's tax obligations in their home country, particularly in relation to estate or inheritance tax. Two frameworks deserve particular attention: the UK's inheritance tax regime and the US federal estate tax regime.
Under the UK Inheritance Tax Act 1984, inheritance tax liability is determined principally by domicile, not by tax residency. A UK-domiciled individual - or an individual deemed domiciled in the UK under the rules set out in sections 267 to 267ZB of that Act - may have their worldwide estate subject to UK inheritance tax, regardless of how many years they have lived in the UAE or another GCC country. Changing domicile is a legal step that requires clear evidence of intention and physical severance from the UK. HMRC publishes guidance on deemed domicile and the conditions under which it arises. Expats should not assume that obtaining a UAE residence visa or spending several years in the Gulf is sufficient to change their UK domicile. Consult a tax adviser with UK domicile expertise.
For US citizens and certain US green card holders, the Internal Revenue Code imposes US federal estate tax on the worldwide estate at death, irrespective of where the individual was resident. The relevant provisions are found in Chapter 11 of the Internal Revenue Code (Sections 2001 onwards). US expats in the GCC should also be aware that the US has estate and gift tax treaties with a limited number of countries; the GCC states are not among the countries with a comprehensive US estate tax treaty as of the date of this publication. US persons should consult a tax adviser qualified in US estate planning.
Other nationalities - including those from EU member states, Canada, Australia, and India - face varying levels of estate, inheritance, or succession duty in their home country that may apply to foreign-situated assets or to assets that pass to heirs resident in the home country. Consult a tax adviser familiar with your specific nationality and home-country rules.
Double-Tax Treaties and Their Relevance to Estate Planning
Double-tax treaties (DTTs) are bilateral agreements between two countries designed to prevent the same income or gain from being taxed twice. Most DTTs in force between GCC states and major expat home countries cover income taxes - they do not automatically extend to inheritance tax, estate tax, or gift tax unless the treaty specifically includes those taxes.
The UK has a small number of specific estate-duty treaties with other countries, but the UAE, Saudi Arabia, Qatar, Bahrain, Kuwait, and Oman are not parties to a UK inheritance tax treaty as of the date of this publication. This means a UK-domiciled expat who dies while resident in the UAE cannot rely on a treaty to reduce UK inheritance tax liability on their UAE-situated assets.
Similarly, the US has estate and gift tax treaties with a limited number of countries. Expats should verify the current treaty position directly with HMRC (for UK tax) or the IRS (for US tax) and should not rely on income tax DTTs as providing inheritance or estate tax relief. A qualified cross-border tax adviser can confirm the applicable treaty position for your specific nationality.
Wills: Drafting, Registration, and Cross-Jurisdictional Validity
A will drafted in one country is not automatically valid or enforceable in another. Formal validity requirements - such as the number of witnesses, the method of execution, and the requirement for notarisation - differ by jurisdiction. Some countries apply the Hague Convention on the Law Applicable to Succession to Private International Law to determine which country's law governs the succession; GCC states are not parties to the EU Succession Regulation (Brussels IV), which is relevant for expats with assets in EU member states.
For expats with assets in the UAE, the DIFC Wills Service Centre provides a registration mechanism for non-Muslim expats. A DIFC-registered will can direct UAE courts to apply the testator's home-country law to assets situated in the UAE and, in some cases, to shares in UAE companies. The DIFC Wills Service Centre publishes its own guidance on asset coverage and registration requirements; expats should review that guidance directly and engage a DIFC-registered will drafter.
For assets situated in the expat's home country, a will drafted and executed in compliance with the home country's requirements is generally needed. Expats who have property in multiple countries - for example, the UK, UAE, and India - may require separate wills for each jurisdiction, or a carefully structured single will that is expressed to cover assets in specific jurisdictions and is compliant with the formal requirements of each. A cross-border estate lawyer can advise on the appropriate structure. Consult a qualified adviser before relying on a will drafted for one jurisdiction to govern assets in another.
Regularly reviewing and updating wills is important. Changes in asset holdings, family circumstances, or applicable law can affect whether an existing will achieves the intended outcome. This is not a one-time exercise.
Financial Accounts, Beneficiary Designations, and Power of Attorney
In some jurisdictions, financial accounts - including bank accounts, brokerage accounts, and life insurance policies - can pass directly to a named beneficiary outside of the probate or succession process, provided the account allows beneficiary designations and local law recognises such designations. In the US, for example, accounts structured as 'transfer on death' or 'payable on death' accounts, or retirement accounts with named beneficiaries under relevant provisions of the Internal Revenue Code, may pass outside of a will. The availability and legal effect of equivalent structures in GCC countries varies by jurisdiction and by the type of financial institution.
Expats should check with each financial institution directly - whether a UAE bank, a GCC-based brokerage, or a UK or US provider - whether beneficiary designations are available on their specific account type, and whether such designations are recognised as legally operative in the relevant jurisdiction. Do not assume that a beneficiary designation on a US retirement account automatically governs what happens to a UAE bank account.
A lasting or enduring power of attorney (LPA or EPA) is a separate but related instrument that authorises a named person to manage your financial or personal affairs if you become incapacitated. The rules governing the creation and recognition of powers of attorney differ by country. A UK LPA, for example, must be registered with the Office of the Public Guardian under the Mental Capacity Act 2005 before it can be used in the UK. Whether it would be recognised by a UAE bank or court is a separate question requiring local legal advice. Expats should consider whether they need powers of attorney in each jurisdiction where they hold significant assets.
Building a Cross-Border Planning Team
Cross-border estate planning is not a task for a single generalist adviser. The complexity of holding assets across multiple legal and tax systems requires a coordinated team. At a minimum, most Gulf expats with material assets in more than one country should consider engaging: a local GCC legal specialist in each GCC country where assets are held; a qualified estate lawyer in their home country; and a tax adviser who is specifically experienced in cross-border and expatriate tax matters, including any relevant inheritance or estate tax obligations in their home country.
Where life insurance, pensions, or investment portfolios are part of the estate, a financial adviser familiar with cross-border structuring may also be relevant. Pension assets, in particular, can have complex inheritance implications - for example, UK-registered pension schemes may operate outside of the deceased's estate for inheritance tax purposes under certain conditions, while other pension structures may not. Consult a tax adviser for your specific situation.
Coordination between advisers is as important as the quality of each individual adviser. A will drafted without input from a tax adviser may achieve the desired distribution of assets but create an unexpected tax liability in the process. Similarly, a tax-efficient structure may not be legally effective if the will or trust instrument is not correctly drafted for the jurisdictions involved. Expats should expect their advisers to communicate with one another.
This guide is a starting point, not a substitute for professional advice. The rules governing cross-border estates change as domestic laws are updated and as international frameworks evolve. Review your arrangements regularly and always consult a qualified cross-border adviser before taking action.
Frequently asked questions
- Does living in the UAE mean I no longer have to pay UK inheritance tax?
- Not necessarily. UK inheritance tax is determined principally by domicile, not by where you are resident. Under the Inheritance Tax Act 1984, a UK-domiciled individual - or an individual deemed domiciled in the UK under sections 267 to 267ZB of that Act - may have their worldwide estate subject to UK inheritance tax regardless of how long they have been resident in the UAE. Changing domicile is a legal step requiring clear evidence of intent and severance from the UK. Consult a tax adviser with UK domicile expertise. This is not tax advice.
- I am a US citizen living in Qatar. Does the US still tax my estate at death?
- US federal estate tax applies to the worldwide estate of US citizens at death under Chapter 11 of the Internal Revenue Code, regardless of where the individual was resident. Qatar does not have a comprehensive US estate and gift tax treaty. Consult a US-qualified tax adviser for your specific situation. This is not tax advice.
- Is a will I made in the UK valid for my assets in the UAE?
- A will made in the UK may not be automatically recognised or enforceable in the UAE for UAE-situated assets. Non-Muslim expats in the UAE can register a will through the DIFC Wills Service Centre or the Abu Dhabi Judicial Department to direct UAE courts to apply their home-country law to UAE assets. Review the official guidance at difcwills.ae and adjd.gov.ae, and engage a qualified local legal specialist.
- What happens to my UAE bank account if I die without a will?
- If you die without a valid will registered in the UAE, the default succession framework - which is Sharia-based for all residents under Federal Law No. 28 of 2005 - will generally apply to your UAE-situated assets. The specific outcome depends on your family circumstances and the applicable court's interpretation. Consult a UAE-qualified lawyer for advice specific to your situation.
- Do double-tax treaties between the UAE and the UK cover inheritance tax?
- The income tax double-tax treaty between the UAE and the UK covers income and capital gains taxes. It does not cover UK inheritance tax. The UAE and UK do not have a specific estate or inheritance tax treaty. Confirm the current position with HMRC or a qualified tax adviser. This is not tax advice.
- Should I have separate wills for each country where I hold assets?
- Whether you need separate wills for each jurisdiction or a single carefully structured will depends on where your assets are located, the formal validity requirements of each country, and how each country's law interacts with the others. This is a decision for a qualified cross-border estate lawyer who can review your specific asset profile and nationality. Consult a qualified adviser.
- What is a DIFC will and who can use it?
- A DIFC will is a will registered through the Dubai International Financial Centre Wills Service Centre. It is available to non-Muslim expatriates and can direct UAE courts to apply the testator's home-country law to UAE-situated assets covered by the will. The DIFC Wills Service Centre publishes eligibility criteria and asset coverage details at difcwills.ae. Engage a DIFC-registered will drafter for your specific circumstances.
