JTJB International Lawyers

What JTJB International Lawyers does

JTJB International Lawyers Co., Ltd. is a privately held, full-service law firm headquartered in Bangkok, Thailand. Founded in 2005 and currently operating from the Singha Complex Building on New Phetchaburi Road, the firm is led by Managing Partner Naiyachon Tathong and a bench of partners including Bunnasomboon Chaiparinya (Head of Corporate), Kosol Suriyaporn, Krittin Pollagan, and Pornnarong Iamkitsamrith. Across approximately 11-50 employees, JTJB delivers legal services through eight distinct practice areas: Corporate and Mergers & Acquisitions, Customs and Tax, Dispute Resolution & Arbitration, Family, Intellectual Property, Labor and Employment, Real Estate and Property, and Shipping, Maritime & Transportation.

The firm's offering is anchored in Thai regulatory expertise, particularly foreign direct investment, work permits and visas, PDPA compliance, BOI processes, and shipping/maritime and aviation law. Revenue is generated through traditional professional services mechanics — billable hours, fixed fees for defined matters, and retainer arrangements — with enterprise and mid-market clients that include domestic Thai businesses, multinational corporations, and foreign investors navigating Thai ownership restrictions. Distribution is direct (partner-led engagement), while demand generation runs through analyst rankings (Chambers, Legal 500, Asialaw, IFLR1000, Benchmark Litigation), thought-leadership content (articles on PDPA, JV templates, Private School Act), and panel participation at industry events such as Asia Business Connect and the Corporate Legal Counsel Forum.

The firm has been recognized for consecutive years in Shipping & Maritime, Transport, Aviation, and Corporate M&A by major legal directories, with Partner-level attorneys named to Asia Business Law Journal's Thailand Top 100 Lawyers in 2023 and 2024. No proprietary technology platform, AI/ML capabilities, or disclosed revenue figures were identified in the source material; JTJB operates as a traditional partnership-style law firm with a documented BizWings administrative services partnership (October 2023) supporting back-office workflows.
