A Word From Our Founder

Welcome to Our Law Firm

“We are proud to introduce our firm. Backed by years of experience and a dedicated team of professionals, we are committed to delivering the finest legal services, designed specifically to meet each client's legal needs.

Our mission is to provide legal solutions that are reliable, efficient, and effective. The founder began his Bachelor of Laws (S-1) at the Faculty of Law, Universitas Muslim Indonesia in Makassar, then qualified as an advocate, joining firms such as Jhamal Qoedoeboen & Partners, Irwan Yusuf & Partners, and MJA & Partners, and holds a licence from the Indonesian Advocates Association (PERADI).

With mature experience across law — including but not limited to PKPU & insolvency, anti-corruption, economic and business law, contracts and property — and a strong reputation as a negotiator and problem-solver, he founded Lamassiang & Co as the realisation of that knowledge and experience in the field of law.”
