Director
Specialisations: Mediation, Family & Matrimonial
Susan Tay is Director and Managing Partner of OTP Law Corporation, a six-lawyer practice she has built and led for over three decades. Called to the Singapore Bar in 1989, she began her career in civil litigation before founding her own firm just two years later. What began as Ong Tay & Partners evolved into today’s OTP Law Corporation — a firm shaped by her belief that a legal practice should combine independence, technical strength and disciplined management.
Her areas of practice span family and matrimonial law, shareholders’ disputes, civil litigation, conveyancing, real property and trust law. In her early years, she acted extensively in conveyancing matters, including large-scale property transactions and en bloc sales involving multiple households, as well as representing major financial institutions as mortgagees. This foundation in property and asset structures continues to inform her approach to complex matrimonial and trust disputes today.
Family law is where Susan has found her enduring professional calling. She has represented clients in high-conflict custody disputes, complex asset division cases and cross-border marriages. Her notable matters include successful care and control awards for fathers, negotiated multi-million-dollar settlements without litigation, and trust structures secured for children in international families. While she is a firm advocate in court when required, she is equally known for pursuing outcomes that minimise unnecessary damage to already fragile family relationships.
Susan is an accredited mediator with the Singapore Mediation Centre and the Singapore International Mediation Institute. She mediates under various institutional panels locally and regionally, with a particular focus on family and cross-border disputes. More than 90% of her mediated matters have resulted in settlement, many concluded within a single session. She was also among the early cohort of senior practitioners trained as parenting coordinators by the Family Justice Courts.
Her litigation experience extends beyond family law into commercial and technology-related disputes, including high-value injunction applications and complex evidence preservation orders involving digital systems. These matters reflect her comfort with both legal doctrine and operational detail.
Technology has long influenced her management of the firm. As early as 2000, she co-founded a legal-tech venture aimed at digitising law practice operations. Though ahead of its time, that initiative laid the groundwork for OTP Law Corporation’s continuing investment in legal technology and structured workflow systems.
Susan’s leadership philosophy is straightforward: build capability, maintain integrity, and create solutions. OTP Law Corporation stands as a reflection of that approach.
