  • Profile

    Elaine Sum is a matrimonial and family lawyer with over 18 years of experience and attained her qualification as a Private Financial Adjudication in 2023. She deals with a full spectrum of matrimonial matters involving divorce, contentious and non-contentious financial issues, third party’s interests in assets in dispute, and custody, care and control, access, maintenance of children born in and out of wedlock.

    In the early years of her legal career, Elaine handled general civil litigation matters such as trust, contractual and employment disputes. This experience allows her to assist her matrimonial clients with wider perspectives. In 2013, Elaine was trained as a Collaborative Practitioner. She has been included on the Recommended List of the Doyle’s Guide Leading Family & Divorce Lawyer Rankings – Hong Kong, 2023.

    Elaine’s prior work experience in the banking industry and a Hong Kong listed company informs her work on matrimonial cases which involve complex company structures and diverse composition of assets/ liabilities.

    It is Elaine’s firm belief that finding practical solutions within the legal framework for clients is important to help them and the children of the family to move forward with their lives.

    In addition to the above, Elaine is fluent in Cantonese, Putonghua and English. She also speaks Indonesian and the dialect of Hakka and understands the dialect of Shanghainese.
