Thailand's Debt Collection Act B.E. 2558: collector obligations and debtor rights
A plain-language summary of Thailand's Debt Collection Act B.E. 2558 (2015): what collectors must do, what the law prohibits, and how debtors can verify a collector or complain.

Thailand’s Debt Collection Act B.E. 2558 (2015) regulates debt collection so that it is fair, protects debtors from inappropriate practices, and requires collection businesses to operate transparently.
Who must comply
Collectors — both lenders that extend credit in the ordinary course of business and those authorized to collect on their behalf — must comply with the Act. Debt collection businesses must be registered or licensed as the law requires.
Max Group was certified to operate debt collection by the Lawyers Council of Thailand on 22 April 2016.
Key obligations
- Contact only the debtor or a person the debtor has named
- When contacting others to locate a debtor, never reveal that the contact concerns a debt
- Identify the collector and the creditor that authorized the collection
- Contact only at the places and times allowed by law, and not unreasonably often
Prohibited conduct
- Threats, violence, or harm to a person’s body, reputation or property
- Insulting language
- Disclosing the debt to unrelated people
- Envelopes or messages that reveal the contact is about debt collection
- Posing as, or implying one is, a lawyer, government official or government agency

What debtors should do when contacted
