Frequently asked questions
Which language prevails?
The contract should say so. Thai courts work in Thai, so the Thai version matters.

Can you review a contract I already have?
Yes, we review and mark up risky clauses.
Do signatures need witnesses?
Some contracts require witnesses; we advise on formalities.

Our service fee is quoted per case.
