This is genuinely one of the questions I think every expat should ask themselves early, not because anything is wrong, but because a small amount of proper planning now can make an enormous, practical difference for the people you care about later. Here’s how I approach it.

Understanding why this matters more for expats specifically

If you’ve built a life across two or more countries, your assets are likely spread across those same countries too, a home country pension, perhaps a property or condominium in Thailand, bank accounts in more than one currency, maybe investments held on an international platform. Each of these genuinely sits under a different country’s succession laws, and without proper planning, sorting this out can become genuinely more complicated and take considerably longer than it needs to.

The genuinely good news is that this complexity is entirely manageable with the right structure in place. It just needs to actually be put in place, rather than assumed to sort itself out.

Understanding the real value of a Thai will

If you own property, hold bank accounts, or have other assets here in Thailand, having a dedicated Thai will covering these specific assets is genuinely one of the simplest and most valuable pieces of planning available to you. Foreign nationals can genuinely own condominium units in Thailand outright, up to a building’s foreign ownership quota, and succession to these Thai-based assets is governed by Thai law specifically.

Making a will in Thailand is genuinely straightforward under Thai law, though the formal requirements need to be followed properly for the will to be valid. A standard Ordinary Will, drafted properly and ideally in two languages, is genuinely the most cost-effective, practical choice for most foreign nationals here, and a Thai lawyer can put this together for you without it needing to be a complicated or lengthy process.

Worth knowing the value of this kind of planning is genuinely illustrated well by a real situation that’s played out for other expats here in Thailand: a British expat living in Phuket passed away without a Thai will in place. He’d left everything in his UK will to his Thai partner of twelve years, but because they had never formally married under Thai law, the absence of a Thai-specific will meant Thai intestate succession rules applied to his Thai assets instead. His condominium and Thai bank accounts went to his parents back in England rather than his partner, and the whole process took fourteen months to resolve. A simple, properly drafted Thai will would have prevented this entirely, ensuring his actual wishes were carried out quickly and exactly as he intended.

This is genuinely the kind of situation a bit of proactive planning avoids completely, and it’s genuinely one of the most straightforward, cost-effective pieces of planning any expat here can put in place.

Understanding the multi-country will strategy

For expats with assets spread across more than one country, and this genuinely describes most of us, a well-established and effective approach is having separate wills for each country where you hold assets, a Thai will covering your Thai assets specifically, and a will in your home country covering everything there.

The genuinely important part of this strategy is coordination. Each will needs to work alongside the others rather than accidentally conflicting with or revoking one another, worth making sure your beneficiaries, executors, and overall distribution plans are consistent across all your documents. This coordinated approach genuinely streamlines the probate process in each country, reduces legal confusion for your family, and means each jurisdiction can handle its own portion of your estate efficiently and in parallel, rather than everything being tied up waiting on a single, slower, cross-border process.

Understanding your ongoing UK inheritance position

For British expats specifically, worth knowing UK inheritance tax rules have genuinely moved toward a residency-based framework in recent years. This means long-term UK residents living abroad can still have real exposure to UK inheritance tax on worldwide assets, depending on how long you’ve been resident, and how the current residency conditions apply to your specific history and circumstances.

This is genuinely an area where proper, individual review matters, since the specific thresholds, reliefs, and how they apply to you depend on your own residency history and current situation. Worth also knowing double taxation relief exists between the UK and several other countries specifically to prevent the same assets being taxed twice, worth understanding whether this genuinely applies to your specific circumstances.

Understanding trusts as a genuine planning tool

Trusts remain a genuinely well-established and valuable tool for cross-border estate planning specifically. Assets held properly within a trust structure can genuinely be excluded from your estate for inheritance tax purposes, and trusts offer real, practical benefits beyond tax efficiency too, they can help protect assets from disputes among beneficiaries, and give you genuine, ongoing control over how and when your beneficiaries actually receive their inheritance, rather than everything transferring in a single lump sum immediately.

This kind of structure can be genuinely valuable for expat families specifically, particularly where beneficiaries are spread across different countries, or where you want a bit more structure around how and when assets are actually passed on.

Understanding what happens without a will, everywhere

If you die without a valid will covering a particular country’s assets, intestacy rules in that specific country determine how those assets are distributed, and this can genuinely produce results quite different from what you’d actually have wanted, particularly for modern family situations that don’t fit neatly into traditional legal categories, unmarried long-term partners, blended families, or stepchildren, for example. This is genuinely the core reason proper planning matters so much for expats specifically, our family and asset situations often don’t map neatly onto the default assumptions built into any single country’s intestacy rules.

Understanding power of attorney arrangements too

Alongside your will, worth also thinking about arrangements for while you’re alive but unable to manage your own affairs, whether due to illness or incapacity. Powers of attorney covering both health and welfare decisions, and property and financial affairs, let someone you trust act on your behalf if needed, worth knowing these need to be properly registered to be legally usable, and worth making sure these arrangements are consistent with your wider estate planning across the countries relevant to you.

Understanding the practical steps that follow a death overseas

Worth knowing the practical process here in Thailand specifically involves registering the death at the local district office within a defined period, and for foreign nationals, notifying the relevant embassy or consulate too. From there, the probate process for Thai-based assets is handled by the Thai Civil Court with jurisdiction over the deceased’s assets or last domicile, worth having your original will, death certificate, and relevant documentation ready and accessible, this is exactly the kind of practical detail proper planning in advance makes considerably smoother for your family during an already difficult time.

Understanding why coordination genuinely matters most

Across everything covered here, the genuine common thread is coordination. A Thai will for your Thai assets, a home-country will for assets there, consistent beneficiaries and executors across all your documents, proper consideration of your ongoing home-country tax position, and, where it makes sense, a trust structure to add further control and efficiency. None of these pieces are complicated on their own, and put together properly, they genuinely give you real confidence that your wishes will be carried out efficiently, wherever in the world your assets actually sit.

Final thoughts

Planning for what happens to your estate if you pass away overseas is genuinely one of the most valuable, practical things you can do for the people you care about, and it’s genuinely more straightforward to put in place than most people expect. A Thai will for your Thai assets, properly coordinated with your wills elsewhere, is a real, concrete step worth taking sooner rather than later.

Ask Lawrence about your specific estate planning situation to make sure everything is properly coordinated.
