Taxation & Customs Law in Chiang Rai — About us

Chiang Rai is Thailand's northernmost province, bordering both Myanmar and Laos. Trade through the Mae Sai, Chiang Saen, and Chiang Khong crossings — the latter on the 4th Thai-Lao Friendship Bridge — shapes the disputes that actually arise here: customs, cross-border sale contracts, debt recovery where the debtor sits in another jurisdiction, and land disputes across highland farming and tourism areas.

Suwanvara Law Firm has run border-trade and customs matters continuously from its Mekong-side base in the Northeast, so the procedures, paperwork, and workable lines of defence in this class of case are familiar ground. We work in Thai, English, and Chinese, run the file from our Khon Kaen head office and Bangkok branch, and travel to appear at the Chiang Rai Provincial Court as scheduled.
