Thailand Rental Contract: The Checklist That Fits on One Page

1. Parties & capacity

Full names as on ID/passport, address for notices. For a condo, confirm the landlord is the registered owner (title deed / condominium juristic person records) — agents signing without a written power of attorney is a classic sublet-scam entry point.

2. Premises description

Unit number, building name, floor, parking bay (fixed or non-residential lot number), and the inventory list with condition notes and dated photos attached.

3. Term, rent, escalation

Start and end dates, monthly amount in THB, payment date and method, and the renewal/escalation position. Thai standard is a flat rent for the term with a good-faith right of first refusal — a unilateral mid-term increase clause is worth fighting for removal.

4. Deposit & refund protocol

Amount, deduction grounds stated exhaustively, joint inspection requirement, refund within a stated number of days. Insist on the timeline being written.

5. Use, occupants & rules

Residential use, number of occupants, pet terms, and building/juristic-person rules incorporation (pool, renovation hours, short-term-rental prohibition — important, since many condos ban sub-leasing to tourists).

6. Maintenance & utilities split

Small fixes vs structural; aircon servicing vs capital failure; who opens electricity (MEA/PEA) and water, at metered tariff, not landlord-set rates.

7. Stamp duty & copies

0.1% of total rent (cap THB 10,000), within 15 days. Two signed originals; each party keeps one stamped copy.

8. Exit terms

Diplomatic clause (for work-pass holders), notice period for non-renewal (commonly 30–60 days written), and the CC&C default-and-notice path if the landlord wants early termination.

Does a Thailand rental contract need to be in Thai?

No law requires Thai — but for leases over 3 years, only the Thai-language text is registered at the Land Office, and Thai courts read the Thai version as controlling in a bilingual dispute. If either party is Thai, or the building is a juristic-person condo with Thai-only paperwork, a bilingual contract removes the risk entirely. An English-only contract is enforceable for ordinary 1-year condo tenancies; it is the long-term and mixed-nationality cases where the gap bites.

What stamp duty applies to a Thai rental contract?

0.1% of the total rent for the whole term, capped at THB 10,000, payable within 15 days of signing (by the last day of the following month if filing electronically). For a 1-year lease at 20,000 THB/month that is 240 THB — trivial in amount, not in consequence: an unstamped contract is inadmissible as evidence of the lease terms in a Thai court. By local convention the tenant usually bears it; if you agree otherwise, write it down.

How much deposit is normal, and what protects it?

Two months is the Bangkok condo standard (one month security deposit + one month advance rent) for 1-year leases; villas and serviced apartments often ask three. The contract should state the refund timeline (7–14 days after inspection is typical), the exact deduction grounds, and require a joint move-out inspection with dated photos. A deposit clause without an inspection protocol is how most deposit disputes are pre-decided against the tenant.

Do I need the Land Office registration everyone mentions?

Only for leases of 3 years or more: registration at the local Land Office (under the Land Code and Civil & Commercial Code s.538) is what makes the long lease enforceable for its full term against third parties — e.g., if the condo is sold mid-lease. Under 3 years, a signed, stamped contract binds landlord and tenant without any registration.

What clauses do foreign tenants most often get burned by?

Three. (1) No diplomatic clause — expats on transferred work visas stay bound to the full term and forfeit the deposit leaving early; a diplomatic clause exits after a set month with notice and one month penalty. (2) "Landlord may terminate at will" language — void-feeling but often honored in practice because the tenant doesn't know the CC&C requires default + proper notice. (3) Utility passthroughs for electricity at landlord-set rates in house rentals — insist on meter readings and MEA/PWA tariff rates in the contract.
