Your Rights in Thailand

Thai insurance law grants you meaningful rights to dispute denied claims — even as a foreigner or expat living in Thailand.

1

Under Thailand's Non-Life Insurance Act B.E. 2535, insurers must settle valid claims within the period specified in the policy — typically 15 to 30 days after receiving all required documents. Delays can be reported to the OIC.

2

You have the right to request a written denial letter with the specific clause(s) and reasons relied upon. If your insurer provides only a verbal denial, you can demand written confirmation before proceeding.

3

The OIC Arbitration Committee offers free claim dispute resolution. To initiate, you submit a petition to the OIC with your policy, denial letter, and supporting documents. The process typically completes within 90 days.

4

OIC arbitration awards are binding on insurers under Thai law. Insurers that refuse to comply face license suspension or revocation. Consumers retain the right to pursue civil litigation separately.
