About the Firm

Founded by Sopon Sirimongkolrat, Louis & Partners Thailand serves two kinds of clients: foreign investors who need Thailand explained and executed properly, and Thai enterprises doing business with the world. Our lawyers work in English, Thai, and Chinese — in the same file, on the same day.

As a member of Louis Group, we work alongside affiliated lawyers, patent attorneys, and consultants across Taiwan, Japan, and Vietnam. When your matter crosses a border — a factory relocating from Taoyuan to Rayong, a dispute with evidence in two countries — the group works it as one team, so you do not have to coordinate four law firms yourself.

Each member firm of Louis Group practices independently in its own jurisdiction; the group is a strategic alliance, not a partnership. What clients feel is simpler: one conversation, and the right lawyer in the right country picks up the thread.
