Cross-Border Estate Planning for European Expats in Southeast Asia
A European expat living in Malaysia, Singapore, or Thailand with assets in multiple countries faces estate planning questions no single-jurisdiction guide can answer. UK inheritance tax rules, French and German forced heirship, local succession law for foreigners, offshore bond structures, and the US estate tax trap on US-sited investments are all live issues for this client. This guide covers each in the SE Asia and multi-national-European context where they actually arise.
Does UK inheritance tax apply when you live in Malaysia, Singapore, or Thailand?
UK inheritance tax (IHT) applies to worldwide assets for UK-domiciled individuals and long-term UK residents. It applies to UK-sited assets only for those with no UK domicile who have not reached the long-term UK residence threshold. Where you live now is not the determining question. Where your legal domicile lies, and how long you have been UK-resident, is.
From 6 April 2025, HMRC replaced the previous deemed domicile rule (which triggered after 15 years of UK tax residence) with a new long-term UK residence test. Under the new rules, an individual who has been resident in the UK for at least 10 of the last 20 tax years is treated as a long-term UK resident for IHT purposes, meaning their worldwide assets fall within the scope of UK IHT regardless of domicile. Once someone qualifies as a long-term UK resident, they remain within scope for a transitional period after leaving the UK that ranges from three years (for someone who was resident for 10 to 13 years) up to ten years (for someone resident for 20 or more years).
The standard UK IHT nil-rate band is GBP 325,000. Assets above this threshold are charged at 40%. A residence nil-rate band of up to GBP 175,000 may apply when a UK main residence is passed to direct descendants, bringing the combined threshold to GBP 500,000 in qualifying cases, subject to an estate value cap of GBP 2 million above which the additional allowance is tapered away. Both thresholds are frozen until at least April 2030 under current HMRC policy.
For non-UK-domiciled individuals who have never been long-term UK residents, UK IHT applies only to UK-sited assets. This commonly includes UK property, UK bank accounts, and shares in UK-incorporated companies held directly. Foreign currency bank accounts, overseas pensions, and holdings in authorised unit trusts and open-ended investment companies (OEICs) are specifically excluded from the scope of UK IHT for non-UK-domiciled persons, even if the accounts or funds are managed from the UK.
The inter-spouse exemption is unlimited when both spouses are UK-domiciled. Where one spouse is UK-domiciled and the other is non-UK-domiciled, the exemption on transfers to the non-domiciled spouse is limited to the nil-rate band in force at the date of transfer, currently GBP 325,000. The non-domiciled spouse may elect to be treated as UK-domiciled for IHT purposes to remove this restriction, but that election brings their worldwide assets into the scope of UK IHT and should be taken with full understanding of the trade-off.
| Years of UK Residence | IHT Scope | Period Remaining In Scope After Departure |
|---|---|---|
| Fewer than 10 in last 20 years | UK-sited assets only | Not in scope (no long-term UK residence) |
| 10 to 13 years | Worldwide assets | 3 years after leaving the UK |
| 14 years | Worldwide assets | 4 years after leaving the UK |
| 15 years | Worldwide assets | 5 years after leaving the UK |
| 20 years | Worldwide assets | 10 years after leaving the UK |

How does forced heirship work for French, German, Spanish, Dutch, and Romanian expats?
Forced heirship is a civil law doctrine that reserves a compulsory proportion of a deceased person's estate for specific relatives, overriding the freedom to disinherit them by will. It is a feature of French, German, Spanish, Dutch, Romanian, and most other continental European legal systems. A European national living in SE Asia who has assets in both their home country and their country of residence is subject to forced heirship rules from multiple directions simultaneously.
French law (Code Civil) reserves what is known as the reserve hereditaire for the deceased's children. The reserved portion is one-half of the estate for one child, two-thirds for two children, and three-quarters for three or more children. The remainder (the quotite disponible) can be directed by will. A French national in Singapore who holds French property, a Singapore bank account, and a UK pension fund must consider how French succession law applies to the French property and whether the local Singapore position affects the rest of the estate.
German law provides compulsory share rights (Pflichtteil) to direct descendants, parents (where no descendants exist), and the surviving spouse. The Pflichtteil is one-half of the statutory inheritance share that person would receive under intestacy. It is a monetary claim against the estate, not a right to specific assets. A German national in Malaysia who disinherits a child in favour of a spouse can expect the disinherited child to pursue a Pflichtteil claim against the estate through German courts.
Spanish law (Codigo Civil) reserves two-thirds of the estate as a legitima: one-third must pass to descendants equally (the legima estricta) and one-third must eventually pass to descendants but can be directed by will among them (the mejora). Only one-third is freely disposable. Romanian law (Codul Civil, Art. 1088) provides compulsory share rights (rezerva succesorala) to the surviving spouse, children, and parents, each at one-half of their statutory intestate share.
The EU Succession Regulation (Brussels IV, Regulation 650/2012) allows EU nationals to elect for the succession law of their nationality to apply to their entire estate rather than the law of their habitual residence. This election is valuable for a German national living in France, for example, allowing them to opt for German succession law over French. Critically, Brussels IV applies only within EU member states. It does not apply to assets in Malaysia, Singapore, Thailand, or other non-EU countries. The SE Asia assets of a French or German expat will be governed by local law regardless of any Brussels IV election.
| Nationality | Forced Heirship Rule | Reserved Portion |
|---|---|---|
| French | Reserve hereditaire | 1/2 (one child), 2/3 (two children), 3/4 (three+) |
| German | Pflichtteil (cash claim) | 1/2 of statutory intestacy share |
| Spanish | Legitima estricta + mejora | 2/3 of estate to descendants |
| Dutch | Legitieme portie | 1/2 of statutory intestacy share |
| Romanian | Rezerva succesorala (Art. 1088 Codul Civil) | 1/2 of intestate share (children, spouse, parents) |
Table reflects general civil code principles. Cross-border application depends on applicable succession law and applicable treaties. Brussels IV does not apply to SE Asia-sited assets.

What happens to assets held in Malaysia, Singapore, or Thailand when a foreign expat dies?
Each SE Asia jurisdiction applies its own framework to the distribution of assets held within that country when a foreign national dies without a local will. The default outcomes under intestacy often do not reflect what the deceased would have chosen.
Malaysia's Distribution Act 1958 applies to the estates of non-Muslims dying without a valid will in Malaysia. The Act distributes the estate in fixed proportions: if the deceased leaves a spouse and children, the spouse receives one-third and the children share two-thirds equally. If the deceased leaves parents but no spouse or children, the parents receive the estate equally. The Act does not recognise cohabiting partners, step-children without formal adoption, or dependants outside the immediate family. The Malaysian Inheritance (Family Provision) Act 1971 allows certain dependants to apply to court for provision from the estate, but this is a remedial step that adds cost and delay. A foreign national who has lived in Malaysia for 10 or more years, owns Malaysian property, holds Malaysian bank accounts, and has local dependants is running a significant intestacy risk without a Malaysian will.
Singapore applies the Intestate Succession Act 1967 (Cap 146) to non-Muslim estates without a will. The distribution is broadly similar in structure to Malaysia: spouse and children share in defined proportions, with the spouse receiving half and children sharing the other half equally if both are alive. As in Malaysia, a local will executed under Singapore law is the mechanism for directing the distribution of Singapore-sited assets according to the deceased's actual wishes.
Thailand's Civil and Commercial Code (Book VI) governs succession. Heirs are assigned to six statutory classes (descendants, parents, siblings of full blood, siblings of half blood, grandparents, uncles and aunts) with higher classes excluding lower ones entirely. A surviving spouse has a statutory share alongside the relevant class of heirs. Foreign nationals may hold Thai property through certain structures (companies, condominiums), and the local succession law applies to those holdings. A Thai will (testament) must meet specific formality requirements; verbal or informal arrangements have no legal effect.
A critical point for all three jurisdictions: a UK will does not automatically govern locally-sited assets. Grant of probate in Malaysia requires a separate application regardless of any UK grant. The local probate process takes time and cost that a local will significantly reduces. Multi-jurisdiction estates routinely benefit from separate wills for each jurisdiction where significant assets are held, drafted to be compatible rather than conflicting with each other.
Why does holding US-domiciled ETFs create a 40% estate tax problem for European expats?
Most European expats who invest internationally are aware of US equity markets and hold US-domiciled ETFs, often without realising that those instruments create a structural estate tax exposure that does not apply to their Irish-domiciled UCITS equivalents.
The US imposes estate tax on US-sited assets owned by non-resident aliens (individuals who are neither US citizens nor US residents for estate tax purposes) at a rate of up to 40%. The filing threshold for Form 706-NA is USD 60,000 of US-sited assets at the date of death. This threshold is not indexed for inflation and has not changed since it was set. A European expat in KL or Singapore with USD 200,000 invested in a US-domiciled S&P 500 ETF such as SPY or IVV faces US estate tax on USD 140,000 above the threshold at the 40% marginal rate. That is a USD 56,000 potential liability on a position that would have faced no equivalent exposure in an Irish UCITS structure.
The distinction between a US-domiciled ETF and an Irish UCITS tracking the same index is structural, not performance-based. Both products can track the MSCI World, the S&P 500, or global aggregate bond indices. The key differences are: the Irish UCITS is domiciled in Ireland (a member of the EU), and as such its shares are not US-sited property for US estate tax purposes; it accumulates dividends internally (no annual income tax drag on distributions for non-dividend countries); and it is widely available through UK and international brokers. For a non-US person who is neither a US citizen nor a US resident for estate tax purposes, holding Irish-domiciled accumulating UCITS removes the US estate tax exposure entirely without any performance trade-off.
US-sited assets include shares in US-incorporated companies held directly, US bank accounts (with some exceptions), US real property, and shares in US-domiciled investment funds. The estate tax applies at the point of death, not at the point of sale. There is no stepped-up basis equivalent for non-resident aliens that would offset the exposure. The liability falls on the executor or administrator of the estate and must be reported to the IRS within nine months of death.
Some US bilateral estate tax treaties (with the UK, France, Germany, and the Netherlands, among others) provide a proportional credit that can reduce the US estate tax bill for nationals of treaty countries. However, the treaty benefit depends on the specific treaty provisions, the proportion of US-sited to total worldwide assets, and the timely filing of the estate tax return. The treaty route adds complexity and does not eliminate the exposure; it only potentially reduces it. Avoiding US-sited assets in the first place is structurally cleaner.
Can an offshore bond help European expats in SE Asia with estate planning?
An offshore bond (also called an offshore investment bond or portfolio bond) is a life assurance wrapper that holds investment assets within a policy issued by an offshore insurance company, typically in jurisdictions such as the Isle of Man, Guernsey, Luxembourg, or Bermuda. The bond can serve several estate planning functions for a European expat in SE Asia, though it is not a universal solution and its effectiveness depends on the individual's domicile position, the jurisdiction of the provider, and how the policy is structured.
Beneficiary nomination is one of the most immediate estate planning uses. Many offshore bond policies allow the policyholder to nominate beneficiaries directly within the policy documentation. If validly structured, the death benefit under the policy passes to the nominated beneficiaries outside the probate process, without the delay and publicity of a grant of probate in the country of death. This can be valuable for a European expat with family in multiple jurisdictions who wants assets to reach specific beneficiaries promptly regardless of which court system processes the estate.
Holding an offshore bond through a trust adds a further layer of control. A discretionary trust holding an offshore bond allows the trustees to distribute the bond proceeds among a class of beneficiaries at their discretion, which can be useful for multi-generational planning, protecting beneficiaries who are minors, or managing distributions to family members in high-tax jurisdictions. The trust and bond combination is commonly used for UK IHT planning by UK-domiciled individuals. For non-UK-domiciled expats, the IHT analysis of the trust structure depends on whether the trust settled included UK-sited assets and the domicile of the settlor at the time of settlement.
The UK income tax treatment of offshore bonds uses a time-apportionment method when a chargeable event occurs. A policyholder who has held the bond during years of non-UK tax residence can have those years excluded from the gain calculation when the bond is surrendered or an excess withdrawal creates a chargeable event. This mechanism is known as time-apportionment relief (under ITTOIA 2005 s535) and can materially reduce the UK income tax bill on an offshore bond surrendered after years of SE Asia residency. The benefit depends on the proportion of non-UK-resident years to total policy years and on the policyholder's income in the year of surrender.
Offshore bonds do not automatically avoid UK IHT for UK-domiciled or long-term-UK-resident policyholders. The bond's value forms part of the estate for IHT purposes if the policyholder has a beneficial interest at death. Placing the bond in trust before the seven-year clock starts is the standard mechanism for removing it from the estate. The trust settlement is a potentially exempt transfer (PET) for IHT purposes; if the settlor survives seven years from the date of settlement, the settled amount falls outside the estate.

Offshore Bonds for Expats: How They Work DB Pension Transfer and Post-Transfer StructureWhat IHT exemptions and gifting rules are available to European expats within scope of UK IHT?
European expats who are within the scope of UK IHT on worldwide assets can use the same annual gifting exemptions as UK residents. The annual gift exemption is GBP 3,000 per tax year per donor. Any unused allowance from the previous tax year can be carried forward, meaning a donor who made no gifts in 2024/25 can give away GBP 6,000 in 2025/26 without that amount being brought back into the estate.
Gifts above the annual exemption are called potentially exempt transfers (PETs). A PET falls entirely outside the estate for IHT purposes if the donor survives seven years from the date of the gift. If the donor dies within seven years of making the gift, taper relief reduces the effective IHT rate depending on when in the seven-year window death occurs. Gifts made within three years of death are charged at the full 40% rate. Gifts made three to four years before death carry an effective rate of 32%. Four to five years: 24%. Five to six years: 16%. Six to seven years: 8%.
Additional exemptions that are available regardless of the size of the gift include: small gift exemption (up to GBP 250 per person per tax year to any number of recipients, provided no other exemption has been used on the same recipient in that year); gifts on marriage or civil partnership (up to GBP 5,000 from a parent, GBP 2,500 from a grandparent, and GBP 1,000 from any other person); and normal expenditure out of income (regular gifts made from surplus income, not capital, that do not reduce the donor's standard of living).
Gifts between spouses or civil partners are entirely exempt from UK IHT provided both spouses are UK-domiciled. The exemption is limited to GBP 325,000 (the nil-rate band at the date of transfer) where the recipient spouse is non-UK-domiciled. This restriction is often overlooked by mixed-domicile couples in SE Asia: the unlimited inter-spouse exemption people assume applies does not, and the non-domiciled spouse's estate carries a different planning position entirely.
UK pension death benefits, including SIPP death benefits payable to nominees after death, are currently outside the scope of UK IHT. This will change from 6 April 2027 under changes announced in the October 2024 Autumn Budget. From that date, unspent pension death benefits will fall within the scope of UK IHT. For UK-domiciled and long-term-UK-resident expats with significant SIPP assets, the April 2027 reform materially changes the estate planning calculation around pension drawdown sequencing and beneficiary nominations ahead of that date.
How does the estate planning picture differ for British, French, German, Dutch, Spanish, and Romanian expats in SE Asia?
UK domicile, IHT on worldwide assets, pension reform clock running
A British expat in Malaysia or Singapore is the most directly exposed to UK IHT on worldwide assets. UK domicile of origin is hard to shed: it requires a genuine and permanent break with the UK and the acquisition of a domicile of choice in another jurisdiction, which courts assess strictly. For most working British expats who intend to return to the UK eventually, UK domicile of origin persists. Combined with the new 10-of-20-year long-term UK residence test, most British expats in SE Asia remain within the scope of UK IHT on worldwide assets for a period after departure. The April 2027 pension IHT reform adds SIPP death benefits to the scope, making SIPP nomination strategy an immediate priority for those within scope.
Reserve hereditaire, Brussels IV election (EU only), French succession tax on beneficiaries
A French national in KL or Singapore with French property faces the reserve hereditaire on that property regardless of local wills or estate planning. France taxes inheritance in the hands of the beneficiary at rates from 5% to 45% for direct descendants, with an allowance of EUR 100,000 per parent-to-child transfer (as of the current French tax code). The rate for transfers to unrelated individuals reaches 60%. A French national can elect under Brussels IV for French succession law to govern their entire EU-sited estate. This is useful for assets in France but does not extend to SE Asia assets. The French droit de sequestre (right to claim against the estate for underpayment) means the reserve hereditaire is legally enforceable even against foreign-sited assets in some circumstances.
Pflichtteil, Erbschaftsteuer, and the Wegzugsteuer interaction
German inheritance tax (Erbschaftsteuer) applies to German nationals and residents. A German national living in Malaysia is subject to German inheritance tax on worldwide assets if they have been resident in Germany within the last five years or are a German national living abroad (Auslandsinhaber). The Pflichtteil claim by a disinherited descendant is a monetary claim enforceable through German courts regardless of where the deceased lived or where the assets were held. Germany has estate tax treaties with the US and certain other countries, but not with Malaysia, Singapore, or Thailand. A German expat with assets in both Germany and SE Asia carries both German Erbschaftsteuer exposure and SE Asia local succession considerations simultaneously.
Legitieme portie, Dutch succession tax, and AOW pension interaction
Dutch law reserves the legitieme portie (compulsory share) for children at one-half of the intestate statutory share. A Dutch national living in Singapore who has Dutch assets will face Dutch succession tax (successierecht/erfbelasting) on transfers to beneficiaries above exemption thresholds. The Netherlands taxes worldwide assets of Dutch residents and Dutch nationals within 10 years of leaving the Netherlands for inheritance purposes, with a proportional mechanism. A Dutch national who left the Netherlands more than 10 years ago and has no Dutch-resident beneficiaries may fall outside Dutch succession tax scope on SE Asia assets, but the position depends on the specific facts. The Dutch tax treaty network (including with the UK) may provide relief on double-taxed estates.
Legitima, regional variations (Spain), and Romanian rezerva succesorala
Spanish inheritance tax (Impuesto sobre Sucesiones y Donaciones) is a state tax with significant regional variations: the rate and allowances differ substantially between autonomous communities (Andalusia, Madrid, and Catalonia, for example, apply different regimes). Spanish nationals abroad are subject to Spanish inheritance tax on Spanish-sited assets. The legitima restricts testamentary freedom to one-third of the estate. Romanian law provides for the rezerva succesorala, giving compulsory shares to surviving spouses and direct relatives. Romania has a 0% inheritance tax rate for direct relatives (children, parents) under current rules, but the compulsory share right exists regardless of the tax rate. Romanian nationals in SE Asia with Romanian property must ensure Romanian succession rules are addressed alongside the local and UK considerations.
How are SIPP death benefits treated, and why does the April 2027 reform matter?
UK pension death benefits, including unspent SIPP funds at death, are currently outside the scope of UK IHT. The SIPP is a trust-based structure and the funds are not legally owned by the member; they are held by the pension trustees. On death, the trustees have discretion to distribute unspent pension funds among nominated beneficiaries and dependants without those funds forming part of the member's taxable estate. This made the SIPP an efficient vehicle for passing wealth to the next generation tax-efficiently, particularly for those who had other non-pension assets to draw down first in retirement.
From 6 April 2027, under changes announced in the UK Government's October 2024 Autumn Budget, pension death benefits will be drawn into the scope of UK IHT for the first time. Unspent pension funds at death will be included in the deceased's estate for the purpose of calculating the IHT charge. HMRC will collect the IHT from the pension fund before it is distributed to beneficiaries. For a long-term UK resident in SE Asia with a GBP 400,000 SIPP and no other nil-rate band available, the reform creates a potential IHT bill on the pension death benefit that did not previously exist.
The practical response for those within scope is to review beneficiary nominations now, consider whether accelerating pension drawdown ahead of April 2027 changes the overall estate picture (drawing pension down into an ISA or offshore bond may be worth modelling), and ensure that current expressions of wishes held by the SIPP provider are up to date and consistent with overall estate planning goals. The nomination form held by the pension provider is a statement of wishes; the trustees are not bound by it but follow it in the vast majority of cases. An outdated nomination naming an ex-spouse or deceased parent is a common and easily correctable problem.

What does an unplanned cross-border estate look like for a European expat in SE Asia?
No local will in the country of residence
A European expat with 15 years in Malaysia, a KL property, and MYR bank accounts who holds only a UK will is relying on a document that was drafted under UK law, that does not govern Malaysian-sited assets automatically, and that requires a separate Malaysian grant of probate before local institutions will accept it. Without a Malaysian will, the Distribution Act 1958 defaults apply. The distribution that results may be nothing like what was intended, and the probate process takes significantly longer than it would with a local will in place.
US-domiciled ETFs held in a general investment account
A European expat holding USD 300,000 in a US-domiciled S&P 500 fund in a general brokerage account has an estate tax exposure of up to 40% on USD 240,000 above the USD 60,000 filing threshold. This is not a remote or theoretical risk; it is a real liability at death that is reported to the IRS by the estate executor. Switching to an Irish UCITS tracking the same index removes the exposure entirely. The switch does not require selling and rebuying in all circumstances; it depends on the account structure and tax consequences in the jurisdiction of residence.
Outdated SIPP beneficiary nomination
SIPP providers hold an expression of wishes (nomination form) directing the trustees how to distribute unspent funds on death. Many expats complete this form at the point of joining a scheme and never update it. An expat who divorced, remarried, or had children after the original nomination was filed may have a form naming a former spouse or no dependants at all. The trustees follow the form unless there are compelling reasons not to. Reviewing and resubmitting the nomination form is a 15-minute administrative task with potentially significant financial consequences, particularly ahead of the April 2027 IHT reform.
Assuming home-country succession law governs SE Asia assets
A French national in Singapore who drafts a French will and nominates beneficiaries under French succession law has addressed the French estate. They have not addressed the Singapore estate. The Brussels IV election is available for EU-resident nationals to select their national succession law, but it applies only within EU member states. Singapore is not in the EU. The Singapore Intestate Succession Act applies to Singapore-sited assets regardless of what any French will or Brussels IV election says. A Singapore will is a separate requirement.
Key Takeaway
- UK IHT at 40% applies to worldwide assets for anyone who has been UK-resident for at least 10 of the last 20 years, under rules effective from 6 April 2025.
- The UK nil-rate band is GBP 325,000. The residence nil-rate band can bring the combined threshold to GBP 500,000 where a UK home passes to direct descendants, subject to an estate value cap of GBP 2 million.
- Non-US persons holding US-domiciled ETFs face US estate tax at up to 40% on US-sited assets above USD 60,000. Irish UCITS equivalents carry no equivalent exposure.
- SE Asia succession law applies to locally-sited assets regardless of home-country wills or Brussels IV elections. A local will is not optional for expats with significant SE Asia assets.
- SIPP death benefits are currently outside UK IHT. From 6 April 2027 they will be included. Reviewing nominations and drawdown sequencing in 2026 uses rules still in force.
- The annual UK IHT gift exemption is GBP 3,000 per year. Gifts above the exemption are potentially exempt if the donor survives seven years.
