O’Sullivan Family Law is a specialist family law practice founded and led by Jo O’Sullivan, dedicated to helping clients navigate divorce and separation without resorting to the family court. Recognized as a leader in non-court dispute resolution, the firm focuses on achieving amicable, constructive outcomes with an emphasis on the well-being of any children involved.
The firm is a pioneer of the innovative “One Solicitor, One Couple” process—also known as Solicitor Neutral or Resolution Together—which allows couples to work with a single solicitor for a joint application. This approach, endorsed by the President of the Family Law Division, emphasizes collaboration, mediation, and tailored solutions for families in Brighton, Lewes, Horsham, and surrounding areas. The practice is ideal for couples seeking a respectful, efficient, and less adversarial path through separation.
