Billy strives to make sure his clients get the very best integrated legal advice by often referring to local and international authorities. Recognizing the stress that his clients are going through, he adopts a pragmatic and sensible approach in all his cases, whilst responding to his clients' needs as timely as possible. Billy ensures clear lines of communications, ensuring information is shared openly to maximize efficiency.

Billy regularly advises shareholders of multimillion conglomerate as to the implications a divorce proceeding may have on them and also their businesses. If suitable, Billy also refers to legal principles laid down by leading English cases, which has helped his clients to achieve optimal out-of-court settlements. In many of the cases he deals with, Billy has the ability to think outside the box and be innovative in coming up with a strategy that showcases his legal knowledge in jurisdictions outside of Hong Kong to help his clients achieve their objectives.

When faced with non-complying or untrustworthy opponents, Billy has used his legal knowledge to obtain Court Orders for disclosure, like in CC, YL v C, CSR FCMC 15718/2018 [2019] HKFC 329 with the view of achieving a fair and just resolution for his clients.

On the issue of construction of the “family pot”, especially when it comes to more complicated issues like post-separation income and bonuses, and to minimise the risk of his client's wealth from being exposed by the divorce proceedings, Billy adopts arguments from recognised English authorities like H v H (2007)(supra), CR v CR [2008] 1 FLR 323, P v P [2008] 2 FLR 1135 and B v B [2010] 2 FLR 1214, whilst working closely with Queen's Counsel in English and Wales and Senior Counsel in Hong Kong. Billy's all-rounded approach has often enabled him to achieve sensible financial outcomes for his clients.

In addition to financial settlements, Billy is also involved in children-related cases, as such cases involving relocation application have become very popular of late. Billy is currently representing one of the first Court of Appeal relocation cases in Hong Kong during the COVID-19 outbreak and it is anticipated that the judges in the Court of Appeal will be taking this opportunity to lay down guidelines as to how relocation cases should be dealt with during the pandemic.

Billy is a new generation of divorce lawyers and a strong believer that in this day and age, the term “family law” is no longer limited to divorce but also includes other areas such as guardianship and maintenance claims by certain qualified individuals. When it comes to maintenance claims, Billy acted for the applicant in LYYC v CHL and CSMS, the Executrices of the Estate of CGSK also known as CSKG, Deceased FCMP 223/2017, [2020] HKFC 215 in seeking financial relief against the executrices of the estate of the deceased, who was a very well-known and wealthy businessman. Billy successfully obtained for his client maintenance pending suit and also legal funding against the estate of the deceased gentleman. This was a landmark decision in Hong Kong and the first of its kind.

Billy has contributed to a number of articles on family law for legal publications, such as The Hong Kong Lawyer and STEP Journal, and has conducted seminars focusing on family law. He is also a qualified collaborative practitioner and is a member of the Hong Kong Family Law Association.
