Thailand Late Fee Laws: Rules on Penalties for Overdue Rent

Thailand does not impose a statutory cap on late fees for rent payments. However, there are important legal principles landlords must consider when setting and enforcing late fee policies.

Legal Framework

Contractual Late Fee Provisions

General Principles

Since there is no specific statute, late fees must be specified in the lease agreement to be enforceable. If the lease does not address late fees, the landlord cannot charge them.

Common Market Rates

• Daily penalty of 0.1–1% of monthly rent per day late
• Flat penalty of 5–10% of monthly rent
• These rates are not regulated and vary by contract

Legal Limitations

Under CCC §383, courts have the power to reduce penalties they consider excessive. Therefore, contractual late fees may not be enforced in full if a court determines they are disproportionate to the landlord's actual loss.

Requirements for Business Landlords

Advance Invoicing

Business landlords (3+ units) must:

• Send invoices for rent and utilities
• Deliver invoices at least 3 days before the payment due date
• Clearly itemize the amounts owed

Process for Non-Payment

1. Send a written demand for overdue rent
2. Allow at least 15 days for payment
3. If unpaid, terminate the lease
4. File a court action if the tenant refuses to vacate

See our Eviction Process guide for details.

Default Interest

Under the CCC, if no interest rate is agreed upon in the contract, the default rate for late payment is 5% per annum. Contracts may specify a higher rate, but it must not exceed 15% per annum under the Prohibition of Interest Rate Exceeding the Limit Act.

Best Practices for Landlords

1. Specify late fees clearly in the lease — Include rate, calculation method, and grace period
2. Set penalties at a reasonable level — Excessive fees risk court reduction
3. Send invoices on time — Especially if you are a business landlord (3-day requirement)
4. Keep payment records — Document all receipts and payments
5. Communicate with tenants — Reach out before imposing penalties
6. Include a grace period — 3–5 days is common practice
