Comprehensive advice on all areas of International Family Law

International family law matters often involve complex questions about jurisdiction, relocation, cross-border child arrangements and international finances. Our specialist team provides clear, strategic advice to families navigating legal issues that span more than one country.

Osbornes Law is recognised as one of the leading international family law teams in London. We act in High Net Worth international divorce cases, cross-border financial disputes and highly complex children matters involving the laws of multiple jurisdictions. Our lawyers are experts in international relocation, abduction under the Hague Convention, and enforcement of foreign orders.

Osbornes Law is based in London, but the families we support often have connections around the world. Many of our cases involve parents living in different countries, assets held overseas or disputes that span several jurisdictions. Our team is well-versed in managing cross-border issues and working alongside lawyers abroad. We regularly advise on cases involving Europe (including Spain, France, Germany, Italy and Switzerland), the Middle East (UAE, Qatar and Israel), North America (USA and Canada), Asia (Singapore, Hong Kong and India), and Australia and New Zealand.

We are also home to one of the UK’s leading international adoption teams, and we have specialist expertise in surrogacy, fertility law and cross-border parenthood. Our children’s law team regularly acts in international child arrangement disputes, challenging public law cases, and cases involving serious welfare concerns.

As the Legal 500 states:

“Osbornes offers a unique service of high-quality advice and representation across a wide range of areas of law…this is a very strong team.”

We are also recommended by Chambers UK (High Net Worth section), the Spears HNW Guide and The Times Best Law Firms guide.

Our international family lawyers are all members of Resolution, committed to helping families resolve disputes constructively. We understand the unique pressures of international cases, from urgent injunctions to navigating different legal systems, and provide practical support throughout.
