BANGKOK, THAILAND – Thailand’s rental market entered a new legal era after a series of reforms and court decisions reshaped how leases must be written, registered and enforced.
What Thai rental law covered and why form mattered
Thailand’s rental relationships fell under the Civil and Commercial Code (CCC), specifically sections 537 to 571, and applied in the same way to both foreigners and Thai nationals. There was no separate rental law for non‑Thai tenants, meaning identical rights and duties for all.
Section 538 CCC required that any lease of real estate be in written form to be enforceable in court. Verbal promises, regardless of how trusting the relationship with the landlord appeared, carried no weight in a legal dispute.
Short‑term, long‑term leases and the registration trigger
A lease counted as short‑term if its duration did not exceed three years. For these contracts, a written agreement was sufficient and registration at the Land Department was optional rather than mandatory.
Once a lease term exceeded three years, section 538 CCC triggered a duty to register the agreement with the competent Land Department. Without that registration, the lease could not be enforced beyond the first three years, even if the paper contract promised a thirty‑year term.
Registration fees and the price of skipping the land office
Registration cost 1% of the total rent payable over the full contract term, plus 0.1% stamp duty, for a combined rate of 1.1%. On a monthly rent of 37,800 baht (about 1,000 euros) over 30 years, that translated to roughly 149,688 baht.
These costs were usually shared between tenant and landlord, although the parties could agree otherwise in the contract. Anyone who tried to save money by skipping registration risked losing all legal protection on the lease period beyond the third year in the event of a dispute.
The 30‑year ceiling and the end of 90‑year lease schemes
Section 540 CCC capped the maximum lease duration at 30 years. Longer time frames were automatically reduced by law to 30 years, regardless of what the contract itself stated.
For years, some developers attempted to bypass this limit with “30+30+30” structures, stacking three successive contracts with automatic renewal clauses. Thailand’s Supreme Court struck down this practice in decision No. 4655/2566 from March 2025, declaring such arrangements void and rendering any lease extension promises beyond 30 years legally useless.
Deposits and advance payments under new consumer rules
From September 2025, a new consumer protection regulation came into force for commercial landlords renting out three or more residential units. It set binding limits on how much security deposit and advance rent these landlords could demand.
For contracts up to three years, the combined total of deposit and advance payment was capped at the equivalent of three months’ rent. For long‑term leases, the upper limit was the amount of one full year’s rent, while private landlords with fewer than three units remained subject only to general contract law and were not covered by the new regulation.
Utilities and the ban on extra charges
Commercial landlords were allowed to charge for electricity and water only at the official state tariffs. Any mark‑ups for administration or other costs were expressly banned by the 2025 regulation and could be reported to the authorities in case of violations.
Tenants had the right to request supporting documents for all consumption‑based charges. Landlords were obliged to deliver written invoices for rent and utilities at least three days before payment fell due.
Termination, change of ownership and subletting rules
Section 569 CCC protected tenants when a rented property was sold. A change of ownership did not terminate an existing lease; the new owner stepped into all the rights and obligations of the previous one and the contract continued under the agreed terms.
Subletting was prohibited without the landlord’s express written consent under section 544 CCC. The same applied to using residential premises for commercial purposes, which had to be contractually secured before signing if planned.
Early termination options for tenants and landlords
From September 2025, tenants renting from commercial landlords gained a statutory right to end fixed‑term contracts early. They could do so only after at least 50% of the contract period had elapsed and with 30 days’ written notice.
Landlords were likewise required to give at least 30 days’ written notice to terminate, except in cases of serious breaches of contract by the tenant. In such serious cases, a seven‑day notice period was sufficient.
Repairs, maintenance and where disputes often started
Section 547 CCC obliged the landlord to keep the property in usable condition. Necessary repairs had to be paid by the owner, with the exception of small maintenance items such as changing light bulbs or cleaning filters.
To draw a clear line between minor and major repairs, parties were advised to specify a concrete cost threshold directly in the contract. This reduced potential disputes and increased clarity for both sides.
Move‑in reports and inventories as key protection
The 2025 consumer regulation required commercial landlords to prepare a jointly signed move‑in report to be attached to the lease. Photographs documenting the condition of all rooms and furniture were explicitly part of this requirement.
That report served as the most important protection against unjustified deductions from the security deposit at move‑out. Deposit refunds had to be made immediately or, if an inspection was necessary, within 7 to 14 days after the tenant left the property.
Checklist before signing and limits of general guidance
Before entering into any lease, tenants were urged to verify that they had a written contract and, for terms over three years, that registration with the Land Department was planned. They also needed to ensure that deposit rules, utilities, and termination periods were clearly and fully defined.
The guidance stressed that anyone interested in property in Thailand or needing help with visa and residence matters could obtain qualified advice on the ground. It underscored that complex rental arrangements should be reviewed by a local lawyer before signing and that the information provided did not replace individual legal counsel.
