Demand Letter in Bangkok: Legal Steps Before Taking Action
When a business partner or client in Thailand fails to pay or fulfill their obligations, the first legal step is usually a demand letter.
In Bangkok, where most companies are registered and disputes arise, a properly written demand letter is essential before you can proceed to court or file a police complaint.
1. What Is a Demand Letter?
A demand letter is a formal written notice requesting payment, delivery, or performance under an agreement.
It shows the other party that you are serious, and under Thai civil law, it often serves as official evidence before filing a lawsuit.
For example, if your Bangkok-based contractor fails to refund a deposit or a Thai company ignores your invoices, the court will expect to see that a formal demand letter was sent first.
2. Why Send a Demand Letter in Bangkok Before Suing
- Thai courts expect to see proof of prior demand.
- It gives the debtor a final chance to pay or settle.
- In many cases, it results in faster payment without litigation.
- Helps you recover interest and legal costs later.
- It can be used as evidence for civil or criminal complaints.
3. Key Requirements Under Thai Law
To make your Bangkok demand letter valid and enforceable:
Send via registered post, courier, or email with proof of delivery.
Write it in Thai (attach an English translation for clarity).
Include:
Names of both parties
Summary of facts and breach
The amount due or specific obligation
Deadline (usually 7–14 days)
Payment or contact details
Signature of the authorized person or lawyer
Timeline and Next Steps
| Step | Description | Timeframe |
|---|---|---|
| Step 1 | Review agreement and proof | 2-3 days |
| Step 2 | Draft demand letter (Thai + English) | 1 day |
| Step 3 | Send to debtor’s address in Thailand | 1 Day |
| Step 4 | Grace period | 7 or 14 days or 30 days |
| Step 5 | If no response → legal action | After grace period |
What If the Debtor Ignores the Letter
If there’s no reply or payment within the deadline:
- Your lawyer can proceed with a civil lawsuit.
- For fraud-like behavior, a police complaint may also be filed.
- You may claim interest (7.5–15% per year) and legal fees.
- A second notice may be issued to strengthen the record.
When to Seek Legal Help
Most foreign clients choose a Bangkok-based lawyer to:
- Translate and draft a bilingual demand letter.
- Ensure compliance with Thai civil procedure.
- Handle delivery and follow-up communication.
- Prepare the case if the debtor still refuses to pay.
Bangkok courts require written evidence in Thai, using a local lawyer increases the effectiveness and credibility of your demand.
Common Use Cases
- Unpaid invoice between foreign supplier and Thai buyer
- Deposit refund disputes with Bangkok landlords or developers
- Contractor or freelancer not delivering promised work
- Investment or partnership disputes

Frequently Asked Questions (FAQ)
Q1: Can I send my own demand letter without a lawyer?
Yes, but if written only in English or without legal references, it may be ignored. Thai debtors usually respond better to letters from licensed Thai lawyers.
Q2: How long should I wait before suing?
Normally 7 or 14 days after delivery. Courts consider this a reasonable grace period under Thai civil law.
Q3: Will this work if the debtor is a Thai company?
Yes, the demand should be sent to the registered address listed in the Department of Business Development (DBD) database.
Q4: What if I am overseas?
You can appoint a Thai law firm to issue and deliver the demand on your behalf. All communication can be done online.
