Preparing for Death When Your Life Spans Multiple Countries

Why Single-Will Plans Fail Across Borders

Most people living internationally build their financial life gradually. They open accounts in the UAE, perhaps buy property in Dubai, maintain investments in the US, and slowly accumulate assets across jurisdictions without stopping to ask: "What happens when I die? Which court handles which asset? Which law applies?"

Your natural instinct is to use a single will. You already have one from your home country. It feels complete. It covers your US assets, names your executors, designates guardians for your children. Why make it more complicated?

Because a single US will alone cannot:

• Probate assets held in UAE banks or real estate in Dubai without separate UAE proceedings
• Override local inheritance law in countries with forced heirship rules
• Grant your executor power to access accounts in jurisdictions that don't recognise foreign wills
• Establish guardianship of children in a country based solely on a home country document
• Prevent conflicting court orders from different jurisdictions

The consequence is not abstract. When death notification reaches a UAE bank, the bank freezes all accounts. Your executor has no authority in UAE law to access funds. Your family must hire a local lawyer, obtain probate from a UAE court, and often wait months before any assets move. Meanwhile, your children may be in a jurisdiction where your home country guardianship order carries no weight.

Each jurisdiction has its own rules for who inherits, how probate works, and which court has authority. A coordinated plan honours each set of rules simultaneously. A single will assumes those rules align. They rarely do.

US Estate Tax on Worldwide Assets

This is the most costly gap that expats overlook. US citizens are taxed on worldwide assets regardless of where they live or where they earned the money.

The 2025 federal estate tax exemption is £13.99 million. Under the One Big Beautiful Bill Act (if permanent), the 2026 exemption becomes £15 million. Above that threshold, the tax rate is a flat 40% on excess value. No partial credits for foreign taxes paid.

This applies whether your assets sit in US accounts or abroad. A UAE property, a UK rental, a Dubai business account,all count toward your worldwide estate. Your heirs inherit them net of the US tax bill first.

The exemption sounds large. Until you add it up:

• Primary home in Dubai: £2-4 million
• Investment property elsewhere: £1-3 million
• Liquid savings across multiple currencies: £1-2 million
• Business equity or stock options: £2-5 million
• Pension accounts (if not QDOT structured): valued at death

For many successful expats, the estate crosses the threshold quietly. A couple with £20 million in assets pays roughly £2.4 million in US federal estate tax.

No US-UAE tax treaty exists to reduce this double taxation. This means your estate may owe US federal tax, UAE inheritance tax (if applicable), and potentially taxes in other jurisdictions where assets sit. Professional planning with proper structuring (ILIT, gifting strategies, residence timing) can reduce exposure dramatically, but only if coordinated before death.

Separate Wills: Jurisdiction-Specific Requirements

Each country where you hold significant assets typically requires a separate will governed by that country's law. Not because the law is bureaucratic. Because courts in that jurisdiction will not execute a foreign will without local probate proceedings, and those proceedings can take months or years.

In the UAE specifically, the DIFC (Dubai International Financial Centre) operates under common law, not Sharia law. This matters. A non-Muslim can write a will under DIFC law that applies home country inheritance rules and avoids forced heirship constraints. DIFC Wills Service Centre charges AED 10,000 for a single will or AED 15,000 for mirror wills (coordinated spousal wills).

For assets in Abu Dhabi, the Abu Dhabi Judicial Department (ADJD) manages wills at a lower cost: AED 950 for a single will or AED 1,900 for a couple.

Due to Dubai Law No. 2 of 2025, DIFC courts have exclusive jurisdiction over DIFC-registered wills. This creates clarity. Your heirs know exactly which court to approach.

But coordination matters. If you hold property in Dubai and liquid assets in Abu Dhabi, you likely need separate wills for each. If you also hold US assets, a US will. These three documents must align on major decisions,who the executors are, how assets distribute, who acts as backup,without contradicting each other.

A "mirror will" is a coordinated pair of wills for spouses, usually written simultaneously and deposited in the same jurisdiction. This ensures consistency and reduces the risk that one spouse's will contradicts the other.

UAE Inheritance Law Without a Will

If you die without a will in the UAE, Federal Decree-Law No. 41 of 2022 (updated in 2024) dictates how your assets distribute. Non-Muslims can elect to apply their home country law instead. But this election is not automatic. Your heirs must prove their entitlement and request it.

Without a will and without an election, UAE law applies as default:

• 50% of assets go to the surviving spouse
• 50% divides equally among children, regardless of gender
• Surviving parents, siblings, or grandparents may have secondary claims

This is orderly on the surface. But it assumes your spouse wants to manage all assets jointly with the children. It gives no flexibility for special circumstances: one child with higher needs, a young child who shouldn't control inherited funds yet, or specific bequests you intended.

The 2024 updates clarified that non-Muslims can apply home country law. If you are a US citizen, you can arrange for your US will (or the law of your home state) to govern asset distribution. But this still requires separate proceedings and proof of your election.

UAE has NO inheritance tax. This is favourable. But remember: US citizens still owe US federal estate tax on worldwide assets. So the benefit of UAE's zero inheritance tax is partially offset by US federal exposure.

The Authority Gap: Power of Attorney and Executor Power

One of the most painful gaps expats face is the "authority vacuum" immediately after death.

A power of attorney gives someone authority to act on your behalf while you are alive. That authority dies when you die. It has zero power in any jurisdiction at that moment. Your executor cannot touch bank accounts, sell property, or access safety deposit boxes based on a power of attorney. Only on probate authority,a court order confirming their legal power to manage your estate.

Obtaining probate is jurisdiction-specific. It takes weeks in some places, months in others. During that waiting period, banks freeze all accounts. They have legal obligation to do so. Your family cannot access savings to pay funeral costs, mortgage payments, or living expenses. This creates immediate financial pressure.

This is why a move to a third country where systems restart under different rules becomes critical. If you have accounts in the UAE and your family is in the US, your executors must first get UAE probate to access UAE assets, then transfer funds internationally under currency controls and tax scrutiny. Coordination can reduce this friction substantially.

For cross-border situations, some planners recommend naming multiple executors,one in each major jurisdiction,so probate proceedings can start simultaneously in multiple courts. This requires explicit coordination. If your US will names only a US executor, and your UAE will names only a UAE executor, it works. If they name conflicting people, your heirs face competing court orders and delays.

Life insurance structured through an Irrevocable Life Insurance Trust (ILIT) can provide immediate liquidity when probate freezes everything else. Life insurance proceeds outside the ILIT go into the taxable estate. But structured correctly, they avoid the authority gap and provide ready cash.

Guardianship Across Borders

If you have minor children, guardianship arrangements are critical. And they are jurisdiction-specific.

The court with authority is usually determined by the child's "habitual residence",where the child actually lives, not where you live. If your children live in the UAE, UAE courts have primary authority over guardianship. If one child lives with a grandparent in the US and another lives with you in Dubai, two courts potentially have jurisdiction.

A guardianship order from one country is not automatically enforceable in another. Your US will may designate a guardian, but that order carries no weight in UAE courts without separate UAE proceedings. Your children may end up in legal limbo: one country recognises your chosen guardian, another does not.

The solution is separate guardianship arrangements per jurisdiction. If your children are in the UAE, ask for UAE courts to recognise your guardianship choice. Document this explicitly. If children are in multiple countries, you may need separate guardianship orders in each.

This is not paranoid. It is orderly planning. During the emotional chaos of a parent's death, children need clarity about who is responsible for them and where. Competing guardianship claims delay this clarity and expose children to uncertainty.

Forced Heirship and Elective Share Laws

Some jurisdictions have forced heirship rules. These laws prevent you from completely disinheriting close relatives. Your spouse or children have a minimum entitlement regardless of what your will says.

Sharia-governed jurisdictions (like parts of the UAE) apply forced heirship by default. However, the DIFC (where many Dubai wills are registered) operates under common law. You can write a will under DIFC law that designates heirs freely, without forced heirship constraints.

Similarly, your US will is not subject to forced heirship. You can leave everything to one child and nothing to another, if you choose.

But this creates a subtle danger. If you write a DIFC-governed will that contradicts a Sharia-governed court's expectations (say, excluding a spouse entirely), that court may not recognise the DIFC will without additional proceedings to prove the testator's intent and jurisdiction.

The planning principle is simple: understand the inheritance rules in each jurisdiction where you have assets, and deliberately choose which law will govern each asset. If that choice contradicts the jurisdiction's default law, document your election clearly and keep it accessible to your heirs.

Cross-Border Probate and Asset Distribution

Probate is not universal. There is no "worldwide probate." Each jurisdiction has its own process, timelines, and requirements.

When you die:

• A UAE court issues a probate certificate for UAE assets
• A US court (the state where you had domicile) issues probate for US assets
• A UK court issues probate for UK assets
• Each probate process takes 2-8 months minimum
• Each requires a separate application, proof of death, proof of the will, and payment of local fees

Your executor (or executors) must apply in each jurisdiction simultaneously if possible. But they cannot move assets across borders until both the jurisdiction of origin (releasing the asset) and the jurisdiction of destination (accepting the incoming asset) confirm the transfer.

This is especially complex with bank accounts. A US bank holding funds from a deceased UAE resident will require both a UAE death certificate (often in Arabic, requiring translation and official certification) and a US probate order. The bank's compliance team will scrutinise currency controls, tax reporting, and potential claims from other jurisdictions.

This is why planning includes establishing clear communication with your heirs and executors about where assets are located, which documents they need, and which courts handle which assets. Silence,assuming your family will figure it out,is a recipe for expensive delays.

FBAR and FATCA Reporting Obligations

Even after death, your estate has reporting obligations. These are serious. Penalties for non-compliance are severe.

FBAR (Foreign Bank Account Report): If you hold foreign financial accounts totalling more than £10,000 at any point during the year, you must file an FBAR. This applies to accounts in the UAE, UK, elsewhere,anywhere outside the US. Your estate executor must file the final FBAR after death if applicable.

FATCA (Foreign Account Tax Compliance Act): If you are a US citizen or green card holder, you must disclose foreign financial assets. The threshold is £200,000 at year-end or £300,000 at any point during the year. Again, your estate executor must file the final disclosure.

Failure to file triggers penalties of £10,000 per violation, sometimes escalating to 40% of the unreported asset value.

This means your heirs or executors face substantial reporting obligations immediately. They must gather information about all foreign accounts, calculate aggregate balances, obtain translations and certifications of foreign documents, and file timely reports. This is not optional and not forgiving.

Proper estate planning includes a clear inventory of foreign accounts and assets, stored accessibly so your executor knows exactly what to report and where to find the underlying account statements.

Life Insurance and the ILIT Strategy

Life insurance plays a specific role in cross-border estates: it provides immediate liquidity and, if structured correctly, avoids the probate delays that freeze everything else.

If you own a life insurance policy directly, the proceeds are included in your taxable estate. That means 40% of the proceeds go to US federal tax, then your heirs split the remainder among probate costs, international transfer fees, and actual inheritance.

An Irrevocable Life Insurance Trust (ILIT) owns the policy instead of you. On your death, the policy pays the ILIT's trustee, not your estate. The proceeds bypass probate entirely and are not included in your taxable estate. The trustee uses the funds to pay estate taxes, probate costs, and provide liquidity while other assets are frozen in probate.

There is a critical rule: transfers to the ILIT are subject to a 3-year lookback. If you transfer a policy to the ILIT and die within 3 years, the proceeds are pulled back into your taxable estate. So ILIT planning works best when done well ahead of any health changes.

For cross-border situations, the ILIT structure is particularly valuable because it provides ready cash in a single location (usually the US, where the ILIT is established) while probate proceeds slowly across multiple jurisdictions.

Building a Coordinated Cross-Border Plan

Cross-border estate planning is not about creating the most complex documents. It is about creating the simplest, most coherent system that honours the rules in each jurisdiction without contradiction.

Start with this framework:

• Jurisdiction-by-jurisdiction asset list: Document every asset, where it is held, and which jurisdiction's courts have authority over it
• Separate wills or DIFC registration: For each major jurisdiction with significant assets, establish a will governed by that jurisdiction's law
• Coordinated executor structure: Name executors who can move simultaneously across jurisdictions, or name jurisdiction-specific executors with clear authority boundaries
• Guardianship orders in each jurisdiction: If you have minor children, establish guardianship arrangements that each relevant court recognises
• ILIT for liquidity: If life insurance is part of your plan, structure it through an ILIT to provide immediate cash and avoid probate delays
• Accessible record-keeping: Store copies of all documents (wills, powers of attorney, asset inventory, account statements) in a location your executor and heirs can access quickly

This is not about eliminating complexity. Cross-border life is inherently complex. It is about mapping the complexity clearly so your heirs don't spend months or years discovering it through legal proceedings.

If you are unsure where you stand on any of these points, a short review with an adviser can clarify your position before things get more complicated.

Common Mistakes That Expose Global Assets

Certain patterns repeat across failing cross-border estates:

• Single will for global assets: One US will attempting to cover UAE property, UK rentals, and US accounts. Courts in each jurisdiction reject it without local probate.
• Uncoordinated multiple wills: Separate wills in different jurisdictions that contradict each other on executor roles, distribution percentages, or guardianship.
• Ignoring forced heirship laws: Assuming your will eliminates other family members' claims, only to have courts reorder distribution under local law.
• Not understanding asset situs: Assuming real property follows your will, or that foreign bank accounts can be accessed with your home country power of attorney.
• Outdated guardianship designations: Naming a guardian who no longer lives in the relevant jurisdiction, or failing to register the choice with local courts.
• No documentation of intent: Leaving no clear record of why certain decisions were made, so heirs and courts must guess your intention.

Each of these mistakes is preventable with coordinated planning done while you have time to think clearly.

How Professional Planning Support Actually Fits

For people building lives across borders, professional planning is most valuable when it:

• Provides sequencing, not just documents: Understanding the order in which to establish wills, guardianship orders, and insurance structures so each one reinforces the others
• Challenges comfort-based assumptions: Questioning whether your current documents actually do what you think they do, given the jurisdictions involved
• Protects timing and optionality: Recognising that certain planning windows,like residency changes or property acquisitions,open and close. Acting during calm periods is far easier than acting under pressure.
• Integrates behaviour, not just maths: Acknowledging that your family may not be comfortable navigating foreign courts, so documents need to be simple enough that an executor without legal background can follow them
• Acts as a stabiliser during change: When you move countries, acquire new assets, or have family changes, a good plan bends to accommodate the change without falling apart

The goal is not to "manage money." It is to manage decisions across life stages and jurisdictions so your heirs inherit clarity, not chaos.

The Soft But Decisive Next Step

If you are reading this and thinking:

• "We earn well and have assets scattered across multiple countries, but haven't really stepped back to ask what happens if both of us die"
• "We have wills, but they were written before we moved abroad and probably don't account for our international assets"
• "We know we should plan this, but it feels complex and expensive, so we keep putting it off"
• "One of us has strong convictions about guardianship, but we haven't formalised them in a way that courts will recognise"

Then the next step is usually a structured conversation focused on clarity, not implementation. Not because something is urgent. But because uncoordinated multi-country structures begin to fail quietly at the edges, long before any obvious problem appears. Planning while things are calm is the rare luxury expats often miss, especially when sequencing pressure around banking, residency, and timing tends to surface fastest after a major life change.

Final Takeaway

Cross-border estate planning is not about:

• Creating documents that satisfy every possible scenario
• Avoiding all taxes (impossible and unrealistic)
• Writing wills in every jurisdiction (only in those where you hold significant assets)
• Assuming your heirs will navigate foreign courts without guidance

It is about:

• Mapping which jurisdiction has authority over which assets and decisions
• Understanding the tax exposure you are creating by holding assets globally
• Establishing clear executor authority that works across borders
• Protecting children's interests through jurisdictionally valid guardianship
• Creating a record so heirs know where to start and which documents apply where
• Planning the timing of decisions so you can act calmly, not under pressure

Most people building international lives only realise they didn't have this after something forces the issue: a close relative's death, a health scare, or a major life change that exposes how tangled things actually are. Those who build it early,not perfectly, just early,rarely regret it.
