Probate and Estate Administration for Internationally Mobile Families

Death is the one administrative event nobody can avoid planning for. For internationally mobile individuals who have accumulated assets across multiple jurisdictions — a UK property, a Cyprus bank account, Spanish investments, a UAE QROPS — the process of administering the estate after death is significantly more complex than for someone whose entire financial life is in one country.

This guide explains what probate is, why international estates create multiple parallel processes, what drives the time and cost, and — most practically — how to prepare during life to make the administration after death as straightforward as possible for the people you leave behind.

What Probate Is

Probate is the legal process by which a deceased person's will is validated by a court or registry, and the executor appointed in the will is formally authorised to deal with the estate.

In England and Wales, probate is administered by the Probate Registry (part of HM Courts and Tribunals Service). When a person dies with a will, the executor applies for a Grant of Probate — a legal document confirming the will is valid and the executor has authority to collect assets, pay debts, and distribute the estate to beneficiaries.

If the person dies without a will (intestate), the next of kin applies for Letters of Administration rather than probate — the effect is similar, but the rules on who administers the estate and how it is distributed are determined by the intestacy rules rather than the deceased's wishes.

Without a Grant of Probate (or Letters of Administration), most financial institutions will not release assets. Banks, investment platforms, and share registrars all require sight of the grant before making payments. The grant is therefore the gateway to the estate's assets.

Why International Estates Create Multiple Parallel Processes

An English Grant of Probate is not automatically recognised by courts or financial institutions in other countries. Each jurisdiction tends to require its own equivalent process before assets in that country can be transferred.

Examples:

• A UK property: requires an English Grant of Probate to transfer the title
• A Spanish property: requires an inheritance acceptance process before a Spanish notary, a Spanish succession tax declaration, and registration at the Spanish land registry
• A French bank account: requires a French acte de notoriété from a French notary confirming the beneficiaries, plus proof of payment of French succession tax
• A Cyprus bank account: Cyprus has its own probate process through the District Court; an English grant is typically presented and either resealed or a local grant obtained
• A QROPS in a third country: the QROPS scheme administrator requires appropriate documentation of the death and beneficiary instructions, which varies by scheme

Each parallel process involves:

• Engaging a local lawyer or notary
• Obtaining and translating documents (death certificate, will, English probate)
• Filing tax returns or inheritance declarations
• Paying local succession taxes (where applicable)
• Waiting for the local process to complete

The timeline for each jurisdiction varies from weeks (simple Cyprus bank accounts) to 12-24 months (complex French or Spanish estates with property).

The Time and Cost of International Estate Administration

UK probate timeline:

Simple estates (liquid assets, no disputes, no complex IHT): 4-9 months from death to final distribution Complex estates (property, complex IHT, overseas assets, disputes): 12-36 months or longer

A key bottleneck is HMRC: the IHT account (form IHT400) must be filed and at least an initial IHT payment made before the Probate Registry will issue the grant. HMRC processing times add further delay.

UK probate costs:

Probate solicitor fees: typically £3,000-£15,000 for a reasonably complex estate Probate Registry court fees: £300 flat fee for estates over £5,000; no fee for estates of £5,000 or less (as of 2026 — single flat fee regardless of estate size) Probate solicitor fees for complex estates with multiple properties, disputes, or significant assets: can be 1-2% of the estate value

International costs:

Spanish succession: notary fees, gestor fees, regional succession tax (varies by autonomous community — Madrid applies 99% bonification for direct descendants; most other regions have meaningful rates for amounts above nil-rate thresholds), and land registry fees. Total cost: typically 2-5% of the Spanish asset value French succession: notary fees of 1-3% of estate value; French inheritance tax applies to non-resident beneficiaries above low thresholds (only €100,000 exemption per child between parent and child) Cyprus: moderate legal costs plus any applicable succession duties UAE: DIFC Wills Service Centre wills for non-Muslims cover assets registered in Dubai and provide a more streamlined process; the default without a registered will is UAE civil law (which does not favour non-Muslim foreigners)

What Slows Things Down

Understanding the common causes of delay in estate administration helps executors set realistic expectations and identify problems early:

HMRC IHT processing: the IHT400 must be completed accurately with all supporting valuations. HMRC may raise queries; the back-and-forth can add months.

Disputes: a contested will, an Inheritance Act claim, or a beneficiary dispute dramatically extends timelines. Court proceedings can take years; even threatened claims cause delays until resolved.

Missing assets: if the deceased left no list of their assets, executors must reconstruct the estate from bank statements, correspondence, and enquiries. For internationally mobile individuals with assets at multiple institutions across multiple countries, this can be very time-consuming.

Overseas asset valuations: foreign property valuations, foreign investment values, and business interests in overseas jurisdictions all require professional appraisal. Delays in obtaining these delay the IHT account.

Illiquid assets: if most of the estate is illiquid (property, private equity, collectibles), paying the IHT bill requires either a partial sale or a Heritage Loan (HMRC's facility to pay IHT by instalments where illiquid assets are involved). This extends the overall timeline.

The Excepted Estates Fast-Track

For smaller and simpler estates, a faster process is available. Under the excepted estates regulations, estates within certain value thresholds can avoid the full IHT400 and use the simpler IHT205 (now replaced by the C5 process from 1 January 2022 for UK domiciled estates).

As of 2026, excepted estates include (broadly):

• UK domiciled estates with a gross estate under £3 million AND a net chargeable estate under £650,000 (or £1,000,000 where the entire estate passes to a surviving spouse and the full transferable NRB is available)
• Low value estates (below £5,000) — no grant required at many institutions

For internationally mobile individuals with foreign assets, the excepted estates thresholds consider foreign assets in the calculation of the gross estate. An estate with £200,000 in UK assets and £300,000 in overseas assets is NOT an excepted estate if the overseas assets are UK-taxable.

Practical Preparation: Making Probate Easier

The most valuable thing an internationally mobile person can do for their executors is to prepare for the practical reality of estate administration.

A letter to executors (also called an "asset register" or "legacy binder") setting out:

• All financial accounts (bank, investment, pension, insurance), with account numbers and institution contact details
• All property owned, with details of ownership structure and any mortgages
• Location of the original will and any codicils
• Login details for key online accounts (securely stored)
• Contact details for financial advisers, accountants, and lawyers in each jurisdiction
• Details of any trusts, foundations, or corporate structures
• Any outstanding loans or liabilities

This document should be updated annually and stored securely alongside the will. Tell your executor where it is.

Joint ownership for key assets: assets owned jointly with survivorship rights (joint tenancy rather than tenancy in common) pass to the surviving owner automatically, without probate. For a married couple, the family home in joint names passes immediately to the survivor. The benefit: no probate delay; the drawback: joint tenancy may interfere with certain trust structures and IHT planning.

Pension in trust: nominating a pension beneficiary (completing an expression of wishes form with the scheme) means pension death benefits are paid by the trustees directly to the named beneficiary, bypassing probate entirely. This is fast and avoids the probate delay. Note: under Finance Act 2026, unused pension funds will fall within the deceased's estate for IHT purposes from 6 April 2027. Until that date, pension death benefits remain outside the estate for IHT. From 6 April 2027, the IHT treatment changes — take specific pension advice on the implications for your estate plan.

ISA Additional Permitted Subscription (APS): on the death of an ISA holder, the surviving spouse or civil partner can inherit the ISA tax wrapper through the APS mechanism — they can make an additional subscription of the value of the deceased's ISA, preserving the tax-free status. This does not avoid probate on the underlying assets but minimises the tax cost.

Registered wills for overseas assets: in jurisdictions that operate will registries (France, Spain, Cyprus have registration systems), registering a will simplifies the process for local executors confirming the will and estate structure.
