Thai rental contract: the clauses to read before signing

The Thai rental contract often surprises people by its brevity. Where many Western leases rely on a detailed legal framework, the Thai lease rests mainly on what the parties have written. What is not in the contract will be hard to enforce. Hence the importance of reading it line by line and having anything unclear clarified before signing.

This guide covers the points we check systematically with our clients. It does not replace legal advice: if in doubt about a clause, have it reviewed by a lawyer.

1.The parties, the property, the inventory

Start with the identity of the parties:

• the landlord must be the owner of the property, or someone holding a written power of attorney. Ask for a copy of the title deed (or the page showing the owner) and their ID;
• the tenant: you, with your passport number. If you rent as a couple, both names can be on the contract;
• the property: address, building name, unit number, floor, size.

The inventory (list of furniture and equipment, with their condition) should be attached to the lease. The return of your security deposit will depend on it. Our guide Security deposit in Bangkok: how to get it all back explains how to back it up with dated photos.

2.Term, renewal, notice

The most common term in Bangkok is 12 months. Six-month leases exist, often with higher rent, and some owners accept longer leases with a decreasing rent.

Check:

• the start and end dates;
• renewal conditions: automatic or not, and at what rent;
• the notice required not to renew (often 30 days before the end);
• the early termination clause: what happens if you have to leave before the end? Our guide Leaving before the end of your lease explains the options.

For a lease longer than three years, registration with the Land Office is in principle needed for it to be fully enforceable beyond three years: something to discuss with a lawyer if you are considering a long term.

3.Rent, charges, late payment penalties

The contract should specify:

• the rent and the payment date (often the beginning of the month);
• the payment method: bank transfer to the owner's account, avoiding cash payments without a receipt;
• what is included: common charges (usually paid by the owner), internet, any cleaning;
• electricity and water: billed at the public rate or the building rate? Paid directly or through the owner? See our guide Electricity, water, internet;
• late payment penalties: a daily amount is common; check that it remains reasonable.

4.Security deposit and advance rent

In Bangkok, the most widespread practice is a two-month security deposit and one month's rent in advance, but this varies from property to property. The contract should state:

• the deposit amount and its purpose (covering damage and unpaid rent);
• the time frame for returning it after you hand back the keys;
• the possible deductions and how they must be justified (quotes, invoices).

5.Repairs: who does what

This is a frequent source of disagreement. A usual split:

Have the owner's response time for breakdowns written down: a broken air conditioner in April cannot wait.

6.Clauses to read closely

• Pets: banned in many buildings by the building rules, even if the owner agrees. Check both. See Renting in Bangkok with a dog or cat.
• Subletting and short-term rental: generally prohibited; do not consider them without written consent.
• Occupants: number of people allowed, guests staying over.
• Owner visits: notice before entering the property.
• Works and decoration: nails, paint, changing furniture.
• Address reporting: the owner (or whoever houses you) has a duty to report your address to the immigration authorities; check who handles it.

7.Clauses to negotiate

Many points can be discussed before signing, especially for a lease of 12 months or more:

• extra furniture or equipment (desk, blackout curtains, a second TV);
• a deep clean or air-conditioner servicing before you move in;
• a less costly early termination clause (for example in case of a job transfer);
• an adjusted rent for a longer lease.

8.Renting through an agent: what changes

In Bangkok, most rentals go through an agent. In the most common practice for residential rentals, the agent's commission is paid by the owner, not the tenant: ask clearly from the first contact, and be wary of any intermediary asking for "application fees" before a viewing.

The agent often prepares the contract from a template. That does not spare you from reading it: they also represent the owner, who pays them. A good agent will explain each clause, translate if needed and help you get what was agreed added in writing. They are also a valuable intermediary during the tenancy, in case of a breakdown or disagreement.

Finally, never pay money before seeing the property, in person or on a live video viewing, and checking the owner's identity. Our guide Viewing an apartment remotely explains how to do it from abroad.

9.Thai or English version: which prevails?

Leases are often bilingual, Thai and English. Check which version prevails in case of discrepancy: this is usually stated at the end of the contract. If only the Thai version prevails and you cannot read it, have it translated or reviewed. Sign every page, keep an original copy and photos of every page.

10.Before signing: the checklist
