6 Top UK Divorce Lawyers for Cases Involving Significant International Assets (2026 Guide)

When a couple's wealth sits across multiple countries - London property, a Swiss bank account, a Dubai investment portfolio, a family business registered in the Channel Islands, a holiday home in the South of France - the proceedings become exponentially more complex. Each jurisdiction has its own rules about asset disclosure, enforcement, and what constitutes a marital asset.

English courts have wide-reaching powers to divide assets wherever they are held in the world, but exercising those powers across borders is rarely straightforward. The solicitors in this guide have been selected for their specific expertise in cases where significant assets are held internationally, and where cross-border enforcement, asset tracing, and jurisdictional strategy are central to the outcome.

What to Look For When International Assets Are Involved

• Asset investigation capability. Before you can divide assets, you need to know what exists. In international cases, one party frequently has better knowledge of the asset picture than the other. Your solicitor should know how to use disclosure orders, questionnaires, and forensic investigation to build a complete picture.

• Freezing order experience. If there is a risk that your spouse will move or dissipate international assets, you may need a freezing injunction - sometimes at very short notice. Your solicitor should have experience obtaining these orders and coordinating their enforcement across borders.

• Understanding of offshore structures. Many international asset cases involve trusts, foundations, or corporate vehicles established in jurisdictions like Jersey, Guernsey, the BVI, Cayman Islands, or Liechtenstein. Your solicitor needs to understand how these structures work and how English courts interact with them.

• Enforcement knowledge. An English court order dividing assets is only useful if it can be enforced. Where assets are held abroad, enforcement may require separate proceedings in the relevant jurisdiction. Your solicitor should understand the enforcement landscape and plan for it from the outset.

Frequently Asked Questions

Can English courts divide assets held abroad?
Yes. English courts have the power to make orders over assets wherever they are located in the world. However, enforcement of those orders depends on the laws of the country where the assets are held and whether reciprocal enforcement arrangements exist.

What happens if my spouse hides assets offshore?
English courts take non-disclosure very seriously. If assets are found to have been hidden, the court can draw adverse inferences, make orders on the basis of estimated values, and impose costs penalties. Freezing orders can also be obtained to prevent asset dissipation while investigations continue.

How are international property portfolios valued?
International properties are typically valued by qualified surveyors in the relevant country. The court considers open market value, with deductions for selling costs and any tax liabilities that would arise on disposal. Currency fluctuations can also be a factor in international property cases.

Do I need separate lawyers in each country where assets are held?
Typically, yes - at least for enforcement purposes. Your English solicitor will coordinate the overall strategy while instructing local lawyers in each relevant jurisdiction. The firms listed above all have established international networks to manage this efficiently.

Can a prenuptial agreement protect international assets?
A prenuptial agreement can provide significant protection for international assets, particularly if it is drafted with the laws of multiple jurisdictions in mind. In England, prenups are not automatically binding but are given significant weight following the Supreme Court decision in Radmacher v Granatino (2010).
