Navigating probate for non-domiciled individuals in the UK

Understanding how the UK probate process applies to individuals who are not domiciled in the UK is vital for executors, beneficiaries, and legal professionals alike. The concept of domicile carries significant weight in determining both inheritance tax liabilities and the procedures required to lawfully administer a deceased person’s estate. Navigating the complexities that accompany probate for non-domiciled individuals presents unique legal, practical, and sometimes cross-jurisdictional challenges that must be addressed with care and precision.

This article explores all key aspects of the UK probate process when an individual who was not domiciled in the UK passes away, including definitions, legal frameworks, financial implications, and strategic considerations. It is especially relevant for families, advisors and executors managing international estates with UK-situated assets.

Understanding domicile in UK law

Domicile, under English law, denotes more than simple residency. It refers to a legal concept significantly tied to an individual’s long-term intention and origin. A person acquires a domicile of origin at birth—typically the country of their father (or mother, if the parents are unmarried) at the time of their birth. This domicile remains in place until the person acquires a domicile of choice by settling in another country with the clear and continued intention of remaining there indefinitely.

Importantly, an individual may reside in multiple countries or live in the UK for many years without ever changing their domicile status. Therefore, being a UK resident or holding UK citizenship does not automatically result in acquiring a UK domicile. For the purposes of probate, HM Revenue & Customs (HMRC) will evaluate numerous factors—such as family ties, acquired properties, business interests, and stated intentions—to determine an individual’s domicile status at the time of death.

The implications of domicile status in estate administration

Domicile plays a central role in determining which jurisdiction’s inheritance rules and tax obligations apply to a deceased person’s estate. For non-domiciled individuals in the UK, probate will primarily be concerned with UK-situated assets only. This approach limits the UK probate jurisdiction to assets such as physical property located in England and Wales, company shares registered with UK companies, and cash held in UK banks.

While English law may not govern the entire estate of a non-domiciled deceased person, the portion of the estate that touches UK jurisdiction cannot be administered without engaging with UK probate protocols. Executors must understand the different avenues for applying for a grant of representation, paying inheritance tax (IHT) appropriately, and liaising with legal professionals both in the UK and in the deceased’s home country.

Probate necessity for UK-situated assets

Probate refers to the legal right to deal with someone’s estate after they die. Depending on the asset classes involved, an actual grant of probate or a similar official confirmation might be required before banks release funds, property titles can be transferred, or shares sold.

If the deceased person owned assets in the UK exceeding certain thresholds (typically around £5,000 to £10,000 for banks, and always for real property), a legal representative will likely need to apply to the Probate Registry for a document known as the “Grant of Representation.” For non-domiciled individuals, this is usually a “Grant of Probate” if there is a valid will, or “Letters of Administration” if there is no will.

In cases involving international elements, where the estate is being administered in another jurisdiction, UK institutions usually require either a UK-issued grant or a re-sealed equivalent from certain countries. If the estate is being dealt with in a jurisdiction that has not been designated as probate-reseal compatible under Section 2 of the Colonial Probates Act 1892, then a new UK probate application may be necessary.

Interaction with foreign wills and legal systems

Many non-domiciled individuals who own UK assets may have drafted wills under the succession law of their home jurisdiction. Provided the will is valid under that jurisdiction’s laws, it will often be recognised in the UK for granting probate—so long as it meets the probate standards of the English and Welsh courts. This includes demonstrating testamentary capacity, appropriate witnessing, and clear expression of intent.

It is common practice for advisers to recommend that individuals with cross-border assets prepare multiple wills—one for their home country and another specifically addressing UK-based holdings. While this has the benefit of allowing an executor to deal with each jurisdiction separately, it also demands careful coordination so that the documents do not inadvertently revoke or override each other.

In some cases, foreign wills must be translated and legalised, often via an apostille under The Hague Convention. The probate registry may require a full English translation, accompanied by a certified copy of the original will and the death certificate. Legal practitioners often assist in ensuring that all documentation meets UK evidential requirements.

Inheritance tax considerations

For non-domiciled individuals, the scope of UK inheritance tax is generally limited to assets located within the UK. This contrasts with UK-domiciled individuals, whose worldwide estates are subject to IHT. As of 2024, the standard IHT rate is 40% on the value of an estate above the nil-rate band of £325,000. There are reliefs and exemptions available, including for spouses and certain charitable gifts, but these may apply differently to non-domiciled individuals.

One of the more complex aspects arises when interpreting what constitutes a UK-situated asset. While real estate is unambiguous, other assets—such as non-physical financial interests—may not be straightforward. Shares in a UK-incorporated company are treated as UK assets, regardless of where they are held or traded. Similarly, cash held in a UK bank account remains within scope regardless of the account holder’s nationality.

Special rules exist for long-term UK residents who are non-domiciled, yet deemed domicile for tax purposes. These individuals, who have been UK residents for at least 15 of the previous 20 tax years, are treated as UK domiciled for inheritance tax. As a result, their worldwide estate will fall under the UK IHT scope. For such individuals, detailed tax planning in their lifetime, including use of offshore trusts, may help mitigate exposure.

Initiating probate when the deceased is abroad

Executors or administrators applying for UK probate from abroad face several logistical challenges. The first hurdle is identifying whether a UK application is even necessary. If it is, the executor will need to gather all relevant documents: the original or court-certified copy of the will, an official death certificate, valuations of the UK assets, and identification documentation for themselves. Where there is no will, family members or legal representatives in the deceased’s home country may need to sign affidavits.

In many cases, solicitors in the UK facilitate the process by serving as the executor’s local agent, submitting forms on their behalf and handling HMRC communications. The entire process, from submission to issuance of the grant, tends to take between four and eight weeks—though delays are not uncommon, especially when translations, legalisations, or tax reviews are involved.

Because a grant cannot be issued until HMRC has agreed that IHT (if applicable) is either paid or appropriately accounted for, the Inland Revenue’s processing time becomes critical. For estates liable to tax, the IHT400 form must be submitted with various supplementing schedules—a complex task that often requires input from taxation professionals.

Re-sealing foreign grants in the UK

When the main grant of probate is issued in a jurisdiction within the Commonwealth that has a reciprocal agreement with England and Wales, it may be possible to “re-seal” that probate in the UK, rather than apply afresh. Eligible jurisdictions include Australia, Canada (excluding Quebec), Hong Kong, Singapore, and others.

Provided the original grant is valid and the estate falls under the usual UK asset categories, re-sealing is generally a cost-effective and time-efficient alternative to a full new application. The process involves submitting an application to the Probate Registry along with the sealed copy of the grant, an inventory of UK assets, a death certificate, and evidence of any tax arrangements.

This pathway is particularly appealing for dual-national individuals or retirees who hold property in the UK but spent their final years abroad. That said, careful attention must still be paid to potential IHT exposure and possible conflicts with the local estate administration laws.

Common challenges and pitfalls

Navigating probate for non-domiciled individuals can be fraught with practical difficulties. One frequent area of contention relates to interpreting the legal domicile of the deceased. While families may consider the individual to have “left” their home country, unless a new domicile of choice is firmly established with documentary support, HMRC may challenge the assertion.

Another regular complication arises regarding joint assets or trust arrangements. Executors need to consider whether the deceased held assets jointly and whether UK survivorship rules apply. In addition, offshore trusts established during the deceased’s lifetime may be vulnerable to scrutiny if situated assets were moved for tax planning reasons. Transparency and full reporting are key during IHT filing.

Moreover, cultural or language barriers may impede progress when foreign executors try to reconcile UK legal expectations with local customs. Professional advice, preferably from advisers with international probate experience, can be instrumental in smoothing these transitional hurdles.

Best practices for international estate planning

Proactive estate planning is arguably the most effective way to streamline probate in situations involving multiple jurisdictions. Non-domiciled individuals who know they own UK property or investments should consider:

– Drafting a localised will for their UK assets, ensuring consistency with their main will;
– Establishing whether they may be approaching “deemed domicile” status and seeking tax advice on anticipated IHT liabilities;
– Clarifying asset titling and ownership structures, such as whether properties are owned personally, jointly, via offshore companies or in trust;
– Keeping detailed records of intentions and connections to countries of residence, which may later support domicile arguments;
– Ensuring successors and executors are aware of UK requirements, thresholds and documentation expectations.

By proactively addressing these issues, individuals and their families can avoid unnecessary legal delays, reduce tax exposure, and ensure a smoother estate administration process after death.

Final Thoughts

Probate for non-domiciled individuals with UK assets is a complex intersection of cross-border estate law, tax compliance, and evidentiary requirements. The concept of domicile is not just technical—it can have profound implications on whether a UK grant of probate is needed and how much inheritance tax is due.

For executors, heirs, and advisors navigating such estates, success depends on preparation, accurate documentation, and clear communication across jurisdictions. Engaging experienced UK legal and tax professionals early in the process can help reduce risks, avoid missteps, and bring peace of mind during an already emotionally sensitive time.

As global mobility increases and more people hold assets across borders, understanding the nuances of UK probate for non-domiciled individuals is no longer niche—it’s essential.
