Carey Olsen advises high-net-worth individuals on a wide variety of family law matters, often in relation to cross-jurisdictional issues. The group is noted for its expertise in pre-nuptial agreements. It is also able to draw on the firm’s wider trusts, property, litigation, corporate and private client teams, where family law overlaps with other areas of law. Marcus Pallot takes the lead, with vast experience in divorce cases, also a well-trodden area for John Kelleher. Suzanne Kingston became a consultant in February 2021, providing expertise in complex financial matters, children arrangements following separation or divorce, and cohabitation matters. Senior associate Lauren Glynn is another key name for divorces and civil partnership dissolutions, as well as complex financial disputes arising from relationship breakdowns.

Counsel Will Whitehead is increasingly active in the team, with commercial property transactional expertise, in addition to experience in construction and development work. Associate Lyndsay Houlette is an expert in mixed-use commercial developments and infrastructure projects.
