Kelvin Ong (王凯民)

Managing Partner

Kelvin is Managing Partner at Contigo Law LLC and is one of the most responsive lawyers in town. He possesses over 11 years of experience in private practice and is a Commissioner for Oaths. Prior to establishing Contigo Law LLC, he was an associate director in a mid-sized law firm.

He read law at the National University of Singapore and graduated with Second Class (Upper) Honours and placed 8th out of 476 candidates in Part B of the Singapore Bar Examinations, scoring distinctions in Criminal Law and Family (Matrimonial) Law.

Kelvin's diverse (and he might add, intense) practice spans across a broad spectrum and different areas of law, including but not limited to his deep interest in the following:

  • credit recovery,
  • shareholder disputes,
  • matrimonial disputes,
  • professional negligence,
  • property disputes,
  • contractual disputes,
  • employment issues,
  • construction disputes,
  • medical negligence,
  • personal injury matters,
  • criminal defence, and
  • defamation.

He cut his teeth in his initial years of practice at some of Singapore's largest law firms, including but not limited to Drew & Napier LLC, and Rajah & Tann Singapore LLP.

Kelvin counts the man on the street, SMEs (B2B and B2C alike) as well as high net worth individuals, military generals, officers, MNCs as part of his ever-growing clientele, whether from Singapore or worldwide.

Having amassed a wealth of experience and appeared at all levels of Court as well as in international arbitration under the auspices of institutions such as the SIAC, he is the type of lawyer you want to have in your corner of the ring. He aspires to assist a wider spectrum of clients and to provide them with bespoke, quality legal service at reasonable rates. Access to justice is paramount and offering unparalleled cost-effective legal solutions is what makes this profession purposeful to him.

Kelvin does not believe in yawn-inducing cookie-cutter, textbook answers but is always ready to weigh in with his creative, practical offerings and commercial solutions. He is relatable, approachable, and is effectively bilingual in both English and Mandarin.

In his free time, Kelvin is a petrolhead who enjoys cycling, imbibing alcoholic drinks, badminton, singing, collecting vinyl records, hiking, and photography. Kelvin also serves as a grassroots volunteer lawyer at Meet The People sessions organised in the constituency of Yu Hua.
