Donny & Ong
Founded in 2013, Donny & Ong is a Kuala Lumpur boutique law firm that combines over a decade of transactional experience with a modern, technology-forward approach to legal practice.
We are built on a simple premise: legal advice should be commercially sharp, efficiently delivered, and aligned with how business actually works. Our partner-led model ensures senior involvement in every matter — no delegation to juniors, no layers between you and the expertise you need.
What makes us different is how we work. We integrate AI and legal technology into our practice to move faster, reduce cost, and deliver with greater precision — without compromising confidentiality or professional standards. This is not a gimmick. It is a deliberate operational advantage shaped by partners who understand both legacy practice and emerging tools.
Our clients range from startups and SMEs to established local and international corporations. We treat every engagement as a partnership — we learn your business, anticipate your risks, and deliver advice that is practical, direct, and built for your commercial reality.
Decade-tested judgement. Future-ready execution. That is Donny & Ong.
