About CHATCHAI Law

Chatchai Law was created by Chatchai Inthasuwan, an ex-partner of a few famous international law firms, i.e., Coudert Brothers Limited, DLA Piper Limited, and Chandler MHM Limited, in December 2024.

Chatchai Law was designed to assist local or international clients who want to contact their lawyers at flexible times in convenient or informal ways.  

Our lawyers’ team will serve the clients efficiently, which is no less than what international law firms would provide, but with lower legal fees comparatively. Our lawyers will, of course, work while on the move.
