Returning to the UK as an Expat? What You Need to Know About Family Law 

Q: What family law issues should expats consider when returning to the UK?

A: Returning expats should consider which country’s courts have jurisdiction over any divorce or financial claims, whether any overseas divorce settlement can be reopened in England and Wales, the status of pre- or post-nuptial agreements, and how to regularise arrangements for children, particularly where relocation involves more than one jurisdiction. Early specialist advice is strongly recommended, as timing can be decisive.

In an increasingly globalised world, it is common for British families to spend significant periods living abroad for work, business, or lifestyle reasons. However, many expats eventually decide to return to the UK. While the logistics of relocation (housing, schooling and employment) often take centre stage, the family law implications of returning to England and Wales can be equally important.

For individuals who have married, separated, or had children while living overseas, relocating to the UK can raise complex legal issues. Understanding these considerations early can help avoid costly legal disputes and ensure that family arrangements are legally robust.

Which Country’s Courts Have Jurisdiction?

One of the first legal questions that may arise when expats return to the UK is jurisdiction, meaning which country’s courts have the authority to deal with family law matters such as divorce, financial remedies, or child arrangements.

For British nationals who have lived or are still living abroad (albeit with a view to moving back), multiple countries may potentially have jurisdiction over their family law matters. The courts of England and Wales will have jurisdiction in the following scenarios:

• Both parties to the marriage or civil partnership are habitually resident in England and Wales
• Both parties were last habitually resident in England and Wales and one of them continues to reside there
• The respondent is habitually resident in England and Wales
• The applicant is habitually resident in England and Wales and has resided there for at least one year immediately before the application was made
• The applicant is domiciled and habitually resident in England and Wales and has resided there for at least six months immediately before the application was made
• Both parties are domiciled in England and Wales
• Only the applicant or respondent is domiciled in England and Wales

If you are a family living between two countries, even temporarily, this could lead to competing proceedings in different jurisdictions.

Even if you are not living in England and Wales, if you retain a British domicile, you or your spouse could choose to issue proceedings here. Domicile is an important concept in English family law. In simple terms, it refers to the country a person regards as their permanent home, even if they are currently living elsewhere. Individuals typically acquire a “domicile of origin” at birth, usually from their father, and this remains unless and until they establish a “domicile of choice” in another country by settling there permanently and intending to remain indefinitely.

For expats returning to the UK, domicile can be highly relevant because even long periods spent living abroad do not necessarily change a person’s domicile. As a result, some expats may still be considered domiciled in England and Wales, which can enable the English courts to hear certain family law claims.

The choice of jurisdiction can have significant consequences. England and Wales is often viewed as a financially generous jurisdiction in divorce proceedings, particularly in cases involving substantial assets or a non-working spouse. It is therefore important for returning expats to seek legal advice promptly if divorce or separation is a possibility.

Cross-border jurisdiction disputes can be expensive and complex. In some cases, the timing of when proceedings are issued can determine which country’s court will ultimately deal with the matter. For this reason, it is advisable to seek specialist legal advice as soon as possible if you believe that a dispute involving multiple jurisdictions may arise.

Sarah has recently advised British expats living in Dubai but who retain significant connections to the UK, including the former matrimonial home. There were competing proceedings in the two jurisdictions and Sarah navigated a tricky jurisdiction issue which ultimately enabled her client to obtain a greater settlement than they would have achieved had the matter been dealt with in Dubai.

Pre-Nuptial and Post-Nuptial Agreements in International Marriages

Many expat couples marry abroad or acquire assets in multiple jurisdictions. In these circumstances, pre-nuptial and post-nuptial agreements can play an important role in providing clarity about financial arrangements if the relationship later breaks down.

While pre-nuptial and post-nuptial agreements are not automatically binding in England and Wales, the courts will generally give them significant weight provided that:

• Both parties entered into the agreement freely
• There was full and frank financial disclosure
• Each party had independent legal advice
• The agreement is fair in the circumstances

For internationally mobile couples, these agreements can be particularly valuable in setting out how assets located in different jurisdictions should be treated. They may also help to reduce uncertainty where spouses have connections to multiple legal systems.

For couples returning to the UK after a period abroad, it may be advisable to review any existing pre-nuptial or post-nuptial agreement to ensure that it remains effective and appropriate under English law. In some cases, it may be sensible to update an existing agreement or enter into a post-nuptial agreement after relocating, particularly where the couple has acquired additional assets overseas or their financial circumstances have changed.

Taking legal advice at an early stage can help ensure that any agreement is prepared in a way that maximises the likelihood that it will be upheld by the courts of England and Wales.

Clients who have entered into a pre-nuptial agreement abroad should seek legal advice promptly after returning to the UK. Different countries have very different rules about the validity and effect of pre-nuptial agreements, and an agreement that is binding in one jurisdiction will not be treated as binding by the courts in England and Wales. In England and Wales, pre-nuptial agreements are not legally binding, but the courts may give them significant weight and may hold parties to their terms where it is fair to do so.

Obtaining early advice allows the agreement to be reviewed to assess how likely it is to be upheld in the UK and whether any further steps should be taken to strengthen it. In some cases, it may be sensible for the parties to enter into a new agreement under English law, or to update the existing agreement so that it better reflects the requirements that the English courts typically consider when deciding whether to give effect to a pre-nuptial agreement.

Can You Still Bring Financial Claims After an Overseas Divorce?

Some expats may have already obtained a divorce in another country before returning to the UK. However, an overseas divorce does not always bring financial matters to a complete conclusion.

In certain circumstances, it may still be possible for a spouse to bring a financial claim in England and Wales after a foreign divorce under Part III of the Matrimonial and Family Proceedings Act 1984. This may arise where the financial settlement reached overseas was limited or did not adequately address assets located in, or connected to, the UK.

These types of claims can be legally and procedurally complex. Specialist legal advice at an early stage is therefore important to assess whether a claim may be available and whether the courts of England and Wales are likely to grant permission for such a claim to proceed.

Sarah has experience advising on claims under Part III of the Matrimonial and Family Proceedings Act 1984, including through her work on the seminal case of Potanina v Potanin. Part III allows a party to apply for financial relief in England and Wales following a divorce that has taken place overseas, in circumstances where the financial provision made abroad was insufficient or where there are strong connections to this jurisdiction.

Many clients are unaware that this route exists. This is often because they assume that once a divorce has been finalised in another country, the financial outcome cannot be revisited elsewhere. However, where one or both parties have a sufficient connection to England and Wales (for example through residence, domicile, or assets located here) it may be possible to seek further financial provision from the English court.

Children and International Relocation

Children are often at the centre of legal issues when expat families relocate. Returning to the UK can raise questions about schooling, residence arrangements, and parental responsibility.

If both parents agree to the move, matters may proceed smoothly. However, difficulties can arise if one parent relocates with a child without the consent of the other parent or without a court order. In such cases, the relocation may amount to international child abduction, particularly where the child was habitually resident in another country prior to the move.

The UK is a signatory to the Hague Convention on the Civil Aspects of International Child Abduction, which provides a framework for resolving cross-border child disputes. Parents considering relocating with children should therefore seek legal advice before making any permanent move.

Where parents separate after returning to the UK, the courts in England and Wales will prioritise the best interests of the child when determining living arrangements and contact with each parent.

Sarah’s advice to parents who are considering returning to the UK with their children is to seek legal advice before making any plans to relocate. Where both parents have parental responsibility, one parent cannot ordinarily remove a child from the country in which they are habitually resident without the consent of the other parent or the permission of the court.

Early legal advice can also help parents understand which country’s courts are likely to have jurisdiction and how a proposed move may be viewed by the court.

Practical Steps for Returning Expats

Expats returning to the UK may benefit from taking proactive steps to manage potential family law issues, including:

• Reviewing marital agreements and considering a post-nuptial agreement where appropriate
• Understanding which jurisdiction may apply to any potential divorce or financial claims
• Clarifying arrangements for children, particularly where relocation is involved
• Seeking early legal advice if separation is anticipated
