Before you hire a lawyer: questions to ask

Q. Who will do my work, and can I meet them at the Bangkok or Phuket office?
Q. What is the fee, what is included, and is it fixed or hourly? Get it in writing.
Q. Are you independent of the seller, agent or other party to this matter?
Q. Which office handles my file, and what is the mobile number for that office?
Walk away if you see…

Walk away if a firm promises a visa outcome, a perfect result, or a fee that is not in writing.
