If you are a British expat living in Hong Kong, Singapore, Dubai, Thailand, Spain or elsewhere, there is perhaps one question you avoid asking yourself:
What would happen to my family if I died tomorrow?
Most expats focus on building wealth, reducing taxes, investing in property, and planning for retirement. Far fewer consider what happens when those assets need to be transferred to the next generation. The reality is that an overseas death can create a complex administrative burden for your spouse, children and executors. Your family would have to deal with multiple countries, multiple legal systems, probate applications, and tax authorities.
Depending on your UK residency history, you may still be exposed to UK Inheritance Tax (IHT), even if you have not lived in the UK for many years. The good news is that you can identify and address many of these issues long before they become problems.
Start with a simple question: What would your Family need to do tomorrow?
Imagine you die unexpectedly while living overseas. Would your spouse know:
- where all your assets are?
- which country houses which assets?
- where your Wills are stored?
- who your Executors are?
- whether UK probate will be needed?
- whether foreign probate will be required?
- whether HMRC need to be notified?
For many families, the answer is no.
Start the planning process by viewing your estate through your family’s eyes, not your own.

Do you have assets in multiple countries?
Most expatriates do. For example, you might own:
In the UK
- Buy-to-let property
- Former family home
- Bank accounts
- ISAs
- Investment portfolios
- Pensions
Overseas
- Local residence
- Local bank accounts
- Local pensions
- Investment accounts
- Offshore structures
- Business interests
- Insurance policies
One of the first exercises in any estate planning review is creating a complete worldwide asset schedule. If your family had to locate everything tomorrow, could they?
This issue becomes particularly important for families with UK property. As we explained in our article on UK property remaining within the Inheritance Tax net for non-residents, UK property often remains one of the largest areas of tax exposure for international families.
Do you need more than one Will?
You should have a Will in each jurisdiction where you hold assets. However, this must be handled carefully because one Will can accidentally revoke another if drafted incorrectly. Always tell your Will Writer about all your other Wills.
Does UK Inheritance Tax still apply even if you pass away abroad?
This is often the first tax question expats ask. The answer depends on far more than your current address. Since April 2025, the UK has moved to a residence-based Inheritance Tax regime, replacing the deemed domicile rules.
This means your UK residence history may be more important than where you currently live. For example, some expatriates may remain within the UK Inheritance Tax regime even after leaving the UK, as per the UK IHT Tail Period, which explains how UK inheritance tax exposure can linger for years after leaving Britain.
Would your overseas assets need to be reported to HMRC?
Foreign assets can be relevant to HMRC. If your estate falls within UK Inheritance Tax reporting requirements, executors will be expected to provide details of relevant worldwide assets. HMRC confirms that overseas assets may be within scope where an individual is treated as a Long-Term UK Resident. [gov.uk] This is why understanding your residence status while alive is so important. Your family should not be trying to solve these questions after your death. They should already know:
- whether worldwide assets are potentially relevant
- which assets are held where
- what records exist
- who will assist them
How does HMRC know about overseas assets?
This question comes up frequently during estate planning discussions. The better question is:
Would your executors know enough to declare the estate correctly?
Modern international tax reporting systems involve significant information sharing between countries and institutions. In addition, executors frequently create a clear information trail when they:
- apply for probate
- transfer assets
- close accounts
- liquidate investments
- sell property
The goal of cross-border estate planning is not to worry about what HMRC might discover. The goal is ensuring your family has a complete, accurate roadmap when the time eventually comes.
What would happen to your UK Property?
The 2027 pension changes mean many expatriates need to rethink plans that may have worked for others; UK property is often the most important and largest-value asset in the estate. The challenge is that property creates both tax and administrative considerations. Questions your family may need to answer include:
- Is there outstanding finance?
- Does UK Inheritance Tax apply?
- Who inherits the property?
- Should the property be sold or retained?
Our article on UK property and inheritance tax for non-residents explains why property often requires separate planning consideration even when the owner lives overseas.
What about Pensions and future UK Tax changes?
Many expatriates mistakenly assume pensions pass tax-efficiently by default. However, recent changes to UK tax legislation have made pension planning increasingly important. In particular, HMRC states: From 6 April 2027, most unused pension funds and death benefits will be included in a deceased person’s estate for UK Inheritance Tax (IHT) purposes.
Families should review how pension assets interact with wider estate plans, particularly under the UK’s evolving Long-Term Residence framework. Read here more about what happens to UK Pensions when an expat passes away.
Our analysis of QNUPS, Long-Term Residence and IHT planning post-2027 highlights why pension planning has become a critical component of cross-border estate planning.
Why Planning before Death matters far more than Administration after Death
Most estate problems stem not from tax, but from confusion. Planning ahead can significantly reduce that burden. The objective is not simply reducing Inheritance Tax (which we can help you with as well). The objective is creating a clear, organised structure that allows your family to administer your estate efficiently, understand their obligations and avoid unnecessary delays. Did you know that 70% of Family Wealth is Lost by the Second Generation?
For many internationally mobile families, this means reviewing Wills, asset ownership, UK residence history and tax exposure together rather than treating them as separate issues.
As we discuss in our broader guide to UK tax planning for Hong Kong residents, changing UK residence-based rules mean estate planning, tax planning and succession planning now need to be considered as a single strategy.
