Deposits, notice periods, and the clauses that actually matter
Thai rental contracts follow a fairly consistent structure nationwide, but the details inside that structure — notice periods, what counts as normal wear and tear, who's responsible for which repairs — vary property by property and are exactly where disputes start. Whether you're renting a condo in Bangkok or a house in Chiang Mai, here's what to read carefully before you sign.
Most residential leases run 12 months, though 6-month and month-to-month options exist at a rent premium. Under Thai law, a lease longer than 3 years must be registered at the Land Department to be enforceable for its full term; an unregistered long lease is only enforceable for 3 years. Check what happens at renewal — whether the rent can be raised, and by how much notice.
A lease can technically be verbal, but a written contract is strongly recommended and is what most landlords, agents, and juristic persons expect. Leases longer than 3 years must be registered at the Land Department to be enforceable beyond 3 years, which in practice requires a written, signed agreement.
For a fixed-term lease, notice requirements depend on what the contract itself specifies — commonly 30 days, sometimes 60. For a month-to-month arrangement, either party typically must give notice before the start of the next rental period. Always check the specific clause rather than assuming a default.
No — the deposit is meant to cover unpaid rent and damage beyond normal wear and tear, not routine aging like minor scuffs or faded paint. If a landlord withholds the deposit unreasonably, document the property's condition (ideally with move-in photos) and raise it in writing; persistent disputes can be brought to Thailand's Consumer Protection Board or a local court.

The nationwide norm is two months' rent as a refundable security deposit plus one month paid in advance — three months' rent total before you get the keys. The contract should state exactly what the deposit can be deducted for (unpaid rent, damage beyond normal wear, cleaning) and the timeframe for returning it after move-out, typically 7–30 days.
Check what happens if you need to leave before the lease ends. Many contracts allow early termination with 30–60 days' written notice after a minimum stay (often the first few months), sometimes with a forfeited deposit or an early-termination fee. Some fixed-term contracts have no break clause at all — you're liable for the remaining rent unless the landlord agrees otherwise.
Standard practice splits responsibility: the landlord covers major building systems and structural issues (aircon units, water heaters, plumbing, the roof), while the tenant covers everyday consumables and damage from misuse. A good contract lists specific appliances and who's responsible for repair versus replacement — vague wording here is where most move-out disputes originate.
If you're renting inside a condominium, the building's own juristic-person rules (quiet hours, pet policy, guest registration, renovation restrictions) apply to you as a tenant even though you didn't sign them directly. Ask for a copy before signing your lease — a unit's rent offer usually states the pet policy, but house rules can go further.
Walk through with the landlord or agent and photograph everything: existing scuffs, appliance condition, water pressure, aircon function in every room, and internet speed if it's included. Get any verbal promises (a repair, a furniture swap) written into the contract or a signed addendum — an unwritten promise is unenforceable once you've moved in.
