Late payment penalties for commercial leases in Thailand offer greater flexibility than residential leases, governed primarily by the contract terms.
Late Interest
Per Lease Terms
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 (maximum 15% per annum)
Legal Limitations
Despite the broad contractual freedom:
- Interest must not exceed 15% per annum under the Prohibition Act
- Penalties may be reduced by courts if deemed excessive (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
- Apply late fees per contract terms
- Terminate the lease if default continues beyond the agreed threshold
See our Commercial Eviction Process guide for details.
Best Practices for Landlords
- Specify late fees clearly in the lease — Rate, calculation, grace period
- Set penalties at a reasonable level — To avoid court reduction
- Send invoices on time — Automate where possible
- Keep complete payment records
- Communicate with tenants before taking legal action
