Late payment penalties for commercial leases in Thailand offer greater flexibility than residential leases and are governed primarily by the contract terms under the Thai Civil and Commercial Code (CCC) and the Prohibition Against Calling for Excessive Interest Rate Act B.E. 2560 (2017).
Legal Framework
Contractual Late Fee Terms
Commercial leases typically include stricter late fee provisions:
- Daily penalties of 0.5–2% of monthly rent per day late
- Flat penalties of 5–15% of monthly rent
- Default interest at rates specified in the contract (strictly capped at 15% per annum)
Legal Limitations
Despite the broad contractual freedom:
- Interest must not exceed 15% per annum under the Prohibition Against Calling for Excessive Interest Rate Act B.E. 2560 and CCC Section 654. Any agreement exceeding this rate is void regarding the interest.
- Default Interest is set at 5% per annum (3% base rate plus a 2% surcharge) under the 2021 amendment to CCC Section 224 if no rate is specified in the contract.
- Penalties may be reduced by courts if deemed "disproportionately high" (CCC §383).
- Damages must be proportionate to actual losses.
Non-Payment Process
- Send an invoice per the lease schedule.
- Issue a written demand for overdue rent (must provide at least 15 days' notice per CCC Section 560 if rent is payable monthly or longer).
- Apply late fees per contract terms.
- Terminate the lease if default continues beyond the 15-day statutory notice period or the agreed threshold.
