Estate basics: wills, beneficiaries and cross-border assets

Four channels, not one

The common mental model of estate planning is simple: you write a will, the will says who gets what, and that is what happens.

It is wrong in a way that matters. Assets transfer through at least four distinct channels, and a will governs only one of them. If you have never mapped which channel each of your assets travels through, you do not know where your property will go.

**Channel one: the will.** A will directs the distribution of assets that form part of your estate and are not already committed elsewhere. It is the default channel, and it is the one people think about.

**Channel two: beneficiary designation.** Life insurance policies, some pension and retirement accounts, and certain investment or savings products let you nominate a beneficiary directly with the provider. In many jurisdictions that nomination operates outside the will and takes precedence over it. A will that says "everything to my spouse" does not override a policy naming a former partner from a decade ago. This is the single most common source of unintended outcomes, precisely because the form was signed once and never revisited.

**Channel three: joint ownership.** Property or accounts held jointly may pass automatically to the surviving owner, depending on the form of joint ownership and the law of the place where the asset sits. The will is not consulted. The specific form matters — some kinds of joint holding carry an automatic right of survivorship, others do not, and the same words can mean different things in different legal systems.

**Channel four: operation of law.** Some assets are distributed according to statutory rules regardless of what any document says. Forced heirship provisions in many legal systems reserve fixed shares for particular family members. Matrimonial property regimes in some countries automatically allocate a share of assets to a spouse. Certain employment-related entitlements are paid to statutorily defined dependants.

Writing a will while ignoring the other three channels can produce an outcome nearly opposite to what you intended. The document may be perfect and largely inoperative.

The mapping exercise

Before drafting anything, list every asset you own and write beside each one: which channel it travels through, and which country's law governs it.

Do it for all of these:

• Bank accounts, in each country where you hold one
• Investment and brokerage accounts, noting where the account is held and where the underlying assets are domiciled
• Pension entitlements, employer schemes and end-of-service benefits
• Life insurance policies
• Real property, by country
• Business interests and shareholdings
• Vehicles, safe deposit boxes and physical valuables
• Digital assets, cryptocurrency holdings and the means of accessing them

Most people doing this for the first time find at least one asset they cannot confidently place, and at least one beneficiary designation they have forgotten. Finding those is the entire value of the exercise.

Why cross-border is a different problem, not a harder version of the same one

If all your assets and all your family are in one country, estate planning is a single-jurisdiction question. It can still be complicated, but there is one rulebook.

The moment assets sit in more than one country, you are dealing with **conflicts of law** — the question of which country's rules apply. That question does not have one universal answer, and the countries involved may answer it differently from each other.

Broadly, legal systems use one of two approaches to decide which law governs succession:

• **The law of the deceased's domicile or habitual residence**, applied to their worldwide estate or to their movable property.
• **The law of the place where the asset is located**, applied particularly to immovable property such as land and buildings.

Many systems use a hybrid: the law of domicile for movables, the law of location for immovables. The intergovernmental body that develops conventions in this area maintains instruments addressing applicable law and cross-border recognition Source^source, but not every country is party to every instrument, and coverage is uneven.

The consequence is that a single estate can be split across legal regimes. Real property in country A may be governed by A's rules including any forced heirship provisions. Bank accounts in country B may be governed by the law of your domicile. A pension in country C may follow C's scheme rules regardless of either.

Two documents can conflict

A frequent and expensive mistake: people write a will in each country where they hold assets, and each will contains a standard clause revoking all previous wills. The second will, drafted innocently by a competent local lawyer, revokes the first. The assets the first will covered are now intestate.

If you use multiple wills, each must be drafted with explicit awareness of the others, with revocation clauses carefully limited in scope to the assets in that jurisdiction. This is precisely the kind of drafting that needs a professional who has seen the other documents — not a professional in each country working in isolation.

The alternative is a single worldwide will, which avoids the conflict problem but may be slower or harder to recognise in some jurisdictions. Neither approach is universally better. The choice depends on which countries are involved.

The UAE and Gulf context

For residents of the UAE, the position has specific features worth understanding at a general level.

UAE law contains provisions on personal status and inheritance, and the official government portal sets out arrangements including circumstances in which non-Muslim residents may elect for the law of their home country to apply to the distribution of their estate, and describes the registration channels available for wills Source^source. Several registration options exist depending on the emirate and the type of asset. The details of who may register what, where, and with what effect are administrative matters that change, so they should always be confirmed against current official guidance rather than an article.

Two structural points are stable enough to be worth stating:

**Election is not automatic.** Where a home-country law option exists, it generally requires a positive step — a properly drafted and registered document. Doing nothing is a choice, and it is a choice for the default rules.

**Accounts can be frozen while an estate is resolved.** In many jurisdictions, including but not limited to the Gulf, financial institutions may restrict access to an account on notification of death until succession is established, including some jointly held accounts. Whatever the local rules, the practical planning implication is universal: a surviving spouse or dependant should have access to funds in their own name, sufficient to cover several months of living costs, independent of any account that might be restricted. This single precaution prevents more hardship than most of the sophisticated planning that follows it.

Guardianship, and the decision people delay longest

For anyone with dependent children, the guardianship provision is frequently more consequential than the financial distribution, and it is the clause people put off.

Two things make it harder in a cross-border household:

• The court that decides guardianship is usually the court where the child is present, and it will apply its own standards. A nomination in a will is influential evidence of the parents' wishes, not necessarily binding.
• If the intended guardian lives in a different country, immigration status, travel documents and the practicalities of relocating a child become part of the problem. A nomination that is legally elegant and logistically impossible helps no one.

There is also a gap that catches many families: the period immediately after a death or incapacity, before any court has appointed anyone. Some jurisdictions allow an interim or temporary guardianship arrangement to be documented in advance. Where available, it addresses the days and weeks when the formal process has not yet started.

Tax, and why the answer depends on where the asset sits

Inheritance and estate taxation varies enormously between countries, and the rules that apply are not always the rules of the country where you live Source^source.

Several distinct bases can apply, sometimes simultaneously:

• Tax based on where the **deceased was resident or domiciled**
• Tax based on where the **beneficiary is resident**
• Tax based on where the **asset is located**
• Tax based on the **nationality** of the deceased

The one that surprises people most is the third. Some countries levy tax on assets situated within their borders regardless of the owner's residence or nationality. This can apply to real property, and in some cases to securities issued by companies of that country, held through an account anywhere in the world.

That last point deserves emphasis because it affects a large number of internationally mobile investors who believe they are outside the reach of any estate tax. Holding shares in companies domiciled in a particular country, through a broker in a third country, may still create a taxable connection with the first country. Whether it does, and at what threshold, depends entirely on that country's rules and any treaty in place.

This article deliberately states no rates and no thresholds, because they change and because getting them wrong would be worse than not stating them. The general points that remain true are:

1. Where an asset is located can create a tax connection independent of where you live.
2. Two countries can both claim taxing rights over the same asset, and relief depends on whether a treaty covers estates specifically — many tax treaties cover income but not inheritance.
3. The liability generally falls due before the estate is distributed, which creates a liquidity problem if the estate is mostly illiquid.

That third point is worth planning around directly. An estate consisting largely of property, with a tax or debt liability payable in cash, can force a sale at a bad time under time pressure.

The eight decisions people leave undocumented

Beyond the will itself, these are the items most often missing when an estate is administered. Each one costs the family time, money or both.

1. **An asset inventory.** Executors cannot distribute what they cannot find. Dormant accounts in former countries of residence, old pension entitlements from previous employers and unclaimed policies are routinely lost simply because nobody knew they existed.
2. **Access instructions for digital assets.** Cryptocurrency held in self-custody with no recoverable key is permanently gone. Email accounts, which are the recovery route for almost everything else, are often inaccessible. A sealed record of how access works — stored securely and separately from the credentials themselves — is a practical necessity.
3. **Debt disclosure.** Estates settle liabilities before distributing assets. Undisclosed loans, guarantees given for others and outstanding credit facilities can change the picture entirely.
4. **Documented incapacity arrangements.** A will operates only on death. Losing capacity while alive is a separate scenario needing separate documents — powers of attorney or their local equivalent — and those must generally be valid in the jurisdiction where you are living at the time.
5. **A written note of who to notify.** Employers, insurers, professional bodies, landlords, banks in multiple countries. A single list saves weeks.
6. **Beneficiary designations reviewed after every life event.** Marriage, divorce, births, deaths. This is the most common failure in the entire subject and the easiest to fix.
7. **Currency and location of liquid funds.** If the estate is in one currency and immediate costs are in another, someone will be converting money under pressure at whatever rate is available.
8. **Stated wishes on non-financial matters.** Funeral arrangements, repatriation preferences, care of pets. These are not legal instruments, but their absence causes disproportionate distress at exactly the wrong moment.

Common misconceptions

**"My spouse automatically gets everything."** In some systems, in some circumstances, partly. In others, statutory shares are reserved for children, parents or siblings, and the spouse receives a fraction. Do not assume.

**"A will from my home country is automatically valid where I live."** Formal validity and recognition are separate questions from whether the substance of the will can be given effect. A document may be technically valid and still fail to override local mandatory rules for local assets.

**"I do not have enough for this to matter."** The complexity of an estate is driven by the number of jurisdictions and the structure of the family, not by the value. A modest estate spread over three countries with a blended family is harder to administer than a large one in a single country.

**"Joint ownership solves everything."** It solves some things and creates others. Depending on the jurisdiction and the form of ownership, joint holding may or may not carry survivorship, may create tax consequences at the time it is established, and may expose the asset to the other owner's creditors or divorce.

**"I can write it myself."** For a single-jurisdiction, straightforward estate, standard documents may be adequate in some places. For anything crossing a border, involving a business, involving a blended family or involving a dependant with particular needs, the cost of professional drafting is small relative to the cost of a document that fails when tested.

Where to start

If none of this is in place, the sequence that produces the most protection soonest is roughly:

1. **Complete the asset map**, including the channel and governing jurisdiction for each item.
2. **Review every beneficiary designation** and correct anything out of date. This costs nothing and often fixes the largest single risk.
3. **Ensure the surviving household has independent access to liquid funds**, in their own name, sufficient for several months.
4. **Get professional advice covering all relevant jurisdictions together**, not each separately, before drafting anything.
5. **Address guardianship and incapacity** alongside the will, not after it.
6. **Diarise a review** on a fixed interval and after every major life or residence change.

This article is general education and not legal or tax advice for your circumstances. Succession, personal status and inheritance taxation are jurisdiction-specific, they change, and the interaction between two countries' rules can be counter-intuitive even to specialists in one of them. The purpose here is narrower and, hopefully, more useful: to make sure that when you do take advice, you arrive knowing which questions actually need answering.
