Lease Disputes and Eviction in Thailand: What the Law Says
2 Views
The Three-Year Rule That Decides Everything
The most important provision in Thai lease law concerns form. A lease of immovable property cannot be enforced in court at all unless there is written evidence signed by the party to be held liable. And where a lease runs for more than three years, or for the lifetime of the landlord or tenant, it must be made in writing and registered with the competent official. If it is not registered, the lease is enforceable for three years only.
This catches an enormous number of foreigners who sign long villa or land leases and never register them. The document may say thirty years. Without registration, the enforceable term is three.
Case in point — Supreme Court Judgment No. 1985/2527 (1984): Two shophouse leases were signed on the same day for consecutive terms totalling five years and ten months. Because the arrangement exceeded three years and had not been made in writing and registered, the Supreme Court held it was enforceable for three years only. Significantly, the court held that this limit applies to enforcement in both directions: a party cannot even raise the unregistered excess term as a defence, because enforcement works both ways.
Case in point — Supreme Court Judgment No. 5542/2542 (1999): A twenty-year lease had not yet been registered, but the contract obliged the landlord to attend registration by a fixed date. The Supreme Court held that Section 538 does not require registration at the moment of signing. While unregistered, the lease was binding for three years, and every clause in it, including the promise to register, bound the parties during that period. Because the tenant demanded registration and sued while the lease was still enforceable, the landlord was ordered to register it.
The practical lesson is twofold. Register any lease longer than three years. And if the landlord is stalling, act inside the first three years, because that is the window in which the obligation to register can still be enforced.
The Thirty-Year Ceiling
Immovable property cannot be leased for more than thirty years. Any longer term is automatically reduced to thirty. A lease may be renewed when it expires, but the renewal cannot exceed a further thirty years from the date of renewal.
Two exceptions exist for commercial and industrial use. Leases under the Commercial and Industrial Lease Act can run up to fifty years, renewable for up to a further fifty, but these must be made in writing and registered or they are void. Leases in Eastern Economic Corridor promotion zones have their own fifty-year regime.
The much-marketed structure of a thirty-year lease with automatic renewals to ninety years should therefore be treated with caution. The initial thirty years is secure if registered. The renewals are contractual promises, not registered property rights, and their practical value depends on who owns the land when the time comes.
When a Lease Ends
A fixed-term lease ends automatically when the agreed period expires. No notice is required. A tenant who stays on after expiry without a new agreement is occupying without right.
Where no term was agreed and none can be implied, either party may terminate at the end of any rent period, provided they give notice of at least one rent period in advance. The law caps this: no more than two months' notice is ever required.
The tenant of movable property may return it and terminate at any time at their own expense, but for immovable property the fixed term binds both sides unless the contract says otherwise.
Non-Payment of Rent: The Fifteen-Day Rule
This is where landlords most often go wrong. If a tenant fails to pay rent, the landlord may terminate. But where rent is payable monthly or at longer intervals, the landlord must first notify the tenant to pay within a specified period, and that period must not be less than fifteen days.
Terminate without giving that notice, or give a shorter deadline, and the termination is defective. The tenant then has a real defence, and an eviction claim can fail on that ground alone.
Can a Landlord Change the Locks?
Most online advice says self-help eviction is always illegal in Thailand. The case law is more nuanced, and the difference turns on the contract.
Case in point — Supreme Court Judgment No. 2609/2522 (1979): The lease expressly allowed the landlord to seize the tenant's property and padlock the building if rent was unpaid. When the tenant defaulted, the landlord terminated and chained the entrance shut. The Supreme Court held that because the landlord acted under an express contractual power given with the tenant's consent, and believed in good faith that it was entitled to do so, the required criminal intent was absent. There was no offence of trespass.
Case in point — Supreme Court Judgment No. 4854/2537 (1994): A residential lease allowed the landlord, on default or expiry, to take possession and remove the tenant's belongings. After the term expired and the lease was terminated, the landlord entered, removed the door lock, cut the electricity, and took out the telephone. The Supreme Court held the clauses were not contrary to public order or good morals and were therefore enforceable, so the landlord's conduct disclosed no criminal offence.
Read carefully, these decisions do not licence landlords generally. They turn on an express clause, a lease that had genuinely ended, and good faith. Without such a clause, or where the termination itself was defective, a landlord who locks out a tenant, seizes goods, or cuts utilities is exposed to both criminal complaint and civil liability. Landlords of residential rental businesses face a further layer, because residential letting is subject to consumer contract controls that restrict the terms an operator may impose, so a clause that was enforceable decades ago may not survive scrutiny today.
The safe course for a landlord remains a proper notice followed by a court eviction claim. The safe course for a tenant is to read the default clause before signing.
Eviction Through the Courts
Where the tenant will not leave, the landlord sues for eviction, and usually for unpaid rent and damages at the same time. The claim proceeds as an ordinary civil case: filing, service, mediation, trial, and judgment. If the tenant still refuses to leave after judgment, the landlord enforces through the Legal Execution Department rather than removing them personally.
Timelines depend on complexity, but an uncontested eviction is generally far faster than a contested one, and mediation resolves a significant share of these disputes.
The Six-Month Deadline Landlords Miss
A landlord's claim against a tenant arising out of the lease cannot be brought more than six months after the day the leased property is returned.
This is remarkably short and is routinely overlooked. A landlord who takes the property back, spends a few months getting quotations for damage, negotiates unsuccessfully, and then instructs a lawyer can find the claim already barred. Once the keys are back, the clock is running.
If the Property Is Sold
A lease of immovable property is not extinguished when ownership of the property is transferred. The transferee takes over the transferor's rights and duties toward the tenant.
For tenants this is significant protection: a new owner cannot simply eject you because they bought the property. But the protection is only as strong as the lease itself, which brings the point back to registration. An unregistered long lease that is enforceable for three years passes to the buyer on those terms, not on the terms written in the document.
Deposits and Damage
Disputes over deposits are the most frequent complaint from tenants and the most frequent complaint against landlords. Thai law does not treat the deposit as the landlord's money. It secures the tenant's obligations, and what is properly deducted is unpaid rent and the cost of damage beyond fair wear and tear.
The decisive factor in practice is evidence. A dated, photographed inventory at move-in and move-out settles most of these arguments before they start, and its absence is why so many end badly.
Practical Advice
For tenants: register any lease over three years, insist that the landlord's registration obligation appears in the contract, photograph everything at move-in, read the default and lock-out clauses before signing, and keep proof of every payment. If you receive a notice to pay, check whether it gives you at least fifteen days.
For landlords: put the lease in writing and register it if it exceeds three years, always serve a compliant fifteen-day notice before terminating for non-payment, do not resort to locks and utility cuts unless the contract clearly permits it and the lease has genuinely ended, document the property's condition at handover, and sue within six months of getting the property back.
Frequently Asked Questions
My thirty-year villa lease is not registered. Is it valid?
It is enforceable for three years only. Registration is what gives the longer term legal force, and it should be arranged as a priority.
Can my landlord lock me out for late rent?
Only if the lease expressly permits it and the lease has properly ended. Otherwise the landlord must serve a compliant notice and go to court, and self-help can expose them to criminal and civil liability.
How much notice must I get for unpaid rent?
Where rent is monthly or longer, the landlord must first demand payment within a stated period of not less than fifteen days before terminating.
The property was sold. Do I have to move out?
No. A lease of immovable property survives a transfer of ownership, and the new owner inherits the landlord's rights and duties, subject to the enforceable term of your lease.
How long does a landlord have to sue over damage?
Six months from the day the property is returned. This is one of the shortest limitation periods in Thai law.

Being caught up in a criminal case in a foreign country is one of the most stressful situations anyone can face, and Thailand's system works very differently from what most foreigners expect. There is no jury, cases can be started by the victim rather than only the state, and the language of every hearing is Thai. Whether you are the person harmed by a crime or the person accused of one, understanding how the process works, and where the pressure points are, makes an enormous difference to the outcome. This guide explains how criminal cases in Thailand begin, the difference between a police complaint and a private prosecution, bail, the rights of the accused, and how the case moves through the courts.

Winning a case in Thailand and actually getting paid are two different things. Many creditors discover this the hard way: they obtain a judgment, assume the money will follow, and then find years later that the debtor has moved assets, or worse, that the right to enforce has expired altogether. Thai law gives creditors real teeth, including seizure of property, attachment of bank accounts and salary, and bankruptcy proceedings. But it also regulates how debts may be demanded in the first place, and it imposes a hard deadline on enforcement. This guide explains how debt collection in Thailand works from the first demand letter through to seizure and sale, and the traps that cost creditors their money.
