Do I need a tenancy agreement in Thailand?

Technically no, but practically yes. A written, stamped tenancy agreement is the only reliable protection for both landlord and tenant in Thailand. Without it, disputes over deposits, repairs, and early termination are extremely difficult to resolve.

How much does it cost to stamp a tenancy agreement in Thailand?

Stamp duty is 0.1% of the total rent for leases up to 1 year, or 0.1% of the average annual rent for leases of 1–3 years. For a 2-year lease at THB 25,000/month, that's roughly THB 2880. It must be paid to Revenue Department within 15 days of signing.

Can I renew my tenancy without signing a new agreement?

You can, but it's risky. A verbal renewal or email confirmation has limited legal standing. The safest approach is to either sign a new tenancy agreement for the new period, or sign a short extension addendum to the existing agreement that specifies the new end date and any rent changes.

What is a diplomatic clause in a Thailand tenancy agreement?

A diplomatic clause allows a tenant to terminate the lease early if they are repatriated, transferred abroad, or their Thailand employment ends. It typically activates after the first 12 months of the tenancy with 2 months' written notice. It's standard for expat tenants.

How much security deposit should I charge?

The standard in Thailand is 1 month's deposit for a 1-year lease and 2 months' deposit for a 2-year lease. For furnished properties, some landlords charge an additional month. The deposit must be refunded within 15 days of the tenancy end, less any valid deductions.

Who pays stamp duty — landlord or tenant?

By convention in Thailand, the tenant typically bears the stamp duty. This should be stated clearly in the tenancy agreement. Both parties can agree to split it, but the default is tenant pays.

Is this tenancy agreement legally valid in Thailand?

The agreement is generated based on standard Thailand residential tenancy terms. It covers all major clauses required under Thailand law. However, this is a template tool — for complex situations (commercial properties, disputes, non-standard arrangements), consult a qualified Thailand lawyer.

Can I use this for apartment subletting?

Yes. The tool includes apartment-specific clauses and a reminder to confirm apartment subletting approval has been obtained. Note that it is the landlord's legal responsibility to obtain and renew Land Office registration (leases over 3 years only) before subletting — this tool does not apply for or confirm that approval.

How do I renew a tenancy agreement in Thailand?

Generate a Tenancy Renewal Agreement — a short addendum that extends the existing tenancy with updated rent, new start/end dates, and any changed terms. Both parties sign it and stamp duty applies on the new term. This is cleaner and faster than drafting a new full agreement.

How to renew a tenancy agreement without going through an agent?

You don't need an agent to renew a tenancy agreement in Thailand. If both landlord and tenant agree on the new terms (rent, dates, duration), simply generate a Tenancy Renewal Agreement, review it together, sign it, and pay stamp duty via Revenue Department myStamp within 15 days. The whole process takes under 30 minutes and costs a fraction of agent commission — typically 1 month's rent saved.

What is stamp duty on a tenancy agreement in Thailand?

Stamp duty is 0.1% of the total rent for leases up to 1 year; 0.1% of average annual rent for leases of 1–3 years; and 0.1% of 4× the average annual rent for leases over 3 years. It must be paid to Revenue Department within 15 days of signing. The tenant typically bears this cost by convention.

What is a diplomatic clause in a Thailand tenancy agreement?

A diplomatic clause allows either party to terminate the tenancy early — typically after the first 12 months — with 2 months' written notice, if the tenant is repatriated or their Thailand employment ends. It's standard for expat tenants and protects both landlord and tenant from being locked in if circumstances change.

What is the difference between whole apartment and room rental property tenancy agreements?

whole apartment tenancies have additional restrictions: whole-apartment subletting requires Land Office registration (leases over 3 years only), occupancy caps apply (typically 6–9 persons), and only Thailand Citizens can own apartment units. Private property agreements have fewer restrictions but the same legal requirements — stamp duty, written agreement, and standard deposit/termination clauses.

How to terminate a tenancy agreement early in Thailand?

Check for a diplomatic clause or break clause in your agreement. Without one, the party breaking the lease typically forfeits their deposit or pays compensation equal to the remaining rent liability. Always give written notice and document everything to avoid disputes.

What happens to the security deposit if the landlord sells the property?

The deposit obligation transfers to the new owner at the point of sale. The original landlord is required to hand over the deposit to the buyer at property handover, and the tenant's right to recover the deposit is fully preserved under the new landlord.

Can a landlord increase rent during the tenancy period?

No — rent is fixed for the full duration of the tenancy term as agreed at signing. The landlord can only propose new rent at renewal. Any mid-tenancy rent change requires written mutual agreement from both parties.

What is a break clause in a Thailand tenancy agreement?

A break clause (often called a diplomatic clause in Thailand) gives one or both parties the right to end the lease early after a minimum period — usually 12 months — with a notice period of 1–2 months. It's most common for expat tenants whose employment may end unexpectedly.

What is a CEA tenancy agreement?

The CEA (Council for Estate Agencies) tenancy agreement is a standardised template published by Thailand's real estate regulatory body. It provides a baseline format for residential tenancies covering key clauses like rent, deposit, notice period, and maintenance obligations. While not legally mandatory, it is widely used as a reference. A tenancy agreement generator like SanyaThai builds on the CEA template with additional clauses for apartment subletting, diplomatic termination, and property-specific terms.

How do I renew a whole apartment rental agreement?

To renew an apartment tenancy: (1) Give written notice at least 2 months before the current lease expires. (2) Agree on new rent and duration with the other party. (3) Sign a new tenancy agreement or renewal addendum. (4) Stamp the renewed agreement with Revenue Department within 15 days. (5) Update your apartment subletting record if subletting the whole flat — Land Office registration (leases over 3 years only) must be current. Use SanyaThai's renewal generator to create a stamped-ready renewal agreement in minutes.

What are room rental agreement requirements?

room rental in Thailand requires: the flat owner must be a Thailand Citizen or Permanent Resident, the owner must continue to live in the apartment, the total occupancy must not exceed 6 persons (3-room or smaller) or 9 persons (4-room or larger), non-Malaysian tenants need Land Office registration (leases over 3 years only), and the minimum rental period is typically 6 months. A written room rental agreement covering rent, deposit, house rules, and shared facilities is strongly recommended.

What is a Thailand Tenancy Agreement?

A tenancy agreement (TA) is a legally binding contract between a landlord and tenant that sets out the terms of a residential rental in Thailand. It covers rent, deposit, tenancy period, maintenance responsibilities, and what happens when either party wants to leave early.

Under Thailand law, any tenancy agreement for a period exceeding 9 months must be stamped with the Inland Revenue Authority of Thailand (Revenue Department). Stamp duty is calculated on the annual rent and must be paid within 15 days of signing.

While verbal agreements are technically valid, a written and stamped tenancy agreement is essential for protecting both landlord and tenant — especially when disputes arise over deposits, repairs, or early termination.

whole apartment vs Private Apartment — What's Different?

•Minimum subletting period: 6 months
•Approval must be renewed — whole apartment monitors compliance
•Non-citizen tenants subject to additional restrictions

Private Apartment

•No Land Office registration (leases over 3 years only) needed — landlord has full discretion
•No occupancy cap (subject to building rules)
•Minimum tenancy period varies by property
•Short-term rentals (Airbnb) still prohibited

Stamp Duty on Thailand Tenancy Agreements

All tenancy agreements in Thailand are subject to stamp duty payable to Revenue Department. The duty must be paid within 15 days of signing if the agreement is signed in Thailand, or within 30 days if signed overseas.

Lease Period	Stamp Duty Rate
Up to 1 year	0.1% of total rent
1 to 3 years	0.1% of average annual rent
More than 3 years	0.1% of average annual rent × 4

Stamp duty is typically borne by the tenant. An unstamped agreement is not admissible as evidence in court — making it legally unenforceable until stamped. Calculate on Revenue Department →

whole apartment Landlord, Tampines

“Renting out my 4-room whole apartment for the first time. Agent quoted me THB 2500 just to draft the TA. Used this instead — took about 15 minutes, added aircon servicing and a utility cap, downloaded the PDF. Tenant signed without any issues.”

Priya S.

Expat Tenant, Buona Vista

Feb 2026

“My landlord's original TA had no diplomatic clause. I generated one here, we compared side by side, and ended up using this version instead. The diplomatic clause section alone was worth the THB 100.”

Marcus L.

Condo Owner, Bishan

“Used the renewal feature when my tenant extended for another year. One-page addendum, references the original TA date, clean format. Tenant signed same evening.”
