Thailand Lease Agreements

A residential lease in Thailand has to be in writing to be enforceable, and if it runs over three years it has to be registered. Between those two rules sits a set of terms that decide whether a deposit comes back — and a deposit cap that catches out more landlords than any other rule.

First, which rules apply

Thai residential leasing splits at five units. Below the line, terms are largely what both sides agree. At or above it, a set of mandatory terms applies and cannot be contracted around — including a deposit cap that most private-market habits break.

An owner renting out one condo, or a few. The ordinary Civil and Commercial Code rules apply and the terms are largely whatever both sides agree.

Deposit is by agreement
Two months' deposit plus one month's rent in advance is the Bangkok market norm — convention, not law.
Must be in writing to be enforced
A lease of immovable property cannot be enforced by court action without written evidence signed by the party being held to it.
Over three years must be registered
An unregistered lease longer than three years is enforceable for three years only. Registration at the Land Office costs 1% of the total rent plus 0.1% stamp duty.
Thirty years is the ceiling
The maximum term for a registered lease of immovable property. Longer terms are cut back to thirty years.
Notice follows the contract
Whatever notice period you write in is what applies. If the lease is silent, the Code's default rules fill the gap.

The three-year rule

A lease of immovable property longer than three years must be registered at the Land Office. Leave it unregistered and it is enforceable for three years only — so a client who negotiated five years of security has three. Registration costs 1% of the total rent over the term, plus 0.1% stamp duty. Thirty years is the maximum term; anything longer is cut back to thirty.

The clauses every lease needs

Twelve items. A contract missing any of them is a contract with an argument built into it.

The parties, in full
Full legal names, ID or passport numbers, and registered addresses. For a company landlord, the company name and the signatory's authority to sign.
The property, precisely
Building, unit number, address, and title deed or unit reference. “Condo in Thonglor” is not an identification.
Term and start date
Exact start and end dates. If it runs over three years, it must be registered at the Land Office to bind beyond three.
Rent, and how it's paid
Amount, due date each month, payment method, and the account it goes to. Note any grace period before late fees apply.
Deposit and advance rent
How much is held, what it covers, and the deadline for returning it after handover. Put a number of days on it.
Utilities and common fees
Who pays electricity, water, internet and common area fees. State the rate — overcharging on utilities is where most disputes start.
Repairs and maintenance
The usual split is structural and major appliances to the landlord, minor and consumable to the tenant. Set a baht threshold so it isn't argued each time.
Condition on handover
An inventory list with photographs, signed and dated by both sides on move-in day. This is what the deposit conversation returns to.
Termination and notice
Notice period each side must give, and what counts as a breach. Also what happens if the tenant leaves early.
Renewal terms
Whether there's a right to renew, on what notice, and how any rent increase is calculated.
Subletting and occupants
Who may live there, and whether short-term subletting is allowed. Most condo juristic offices ban daily rentals outright.
Language and governing law
If there's a Thai and an English version, say which prevails. Thai courts work from the Thai text.

Where agents get caught

Six drafting habits that surface months later, usually as a deposit dispute your client expects you to resolve.

  • Using a two-month deposit for a landlord with five or more units

    Instead: Check how many units the landlord rents out before you draft. Over the threshold, one month is the maximum and the excess is unenforceable.

  • No photographic inventory on handover day

    Instead: Twenty minutes of photos, signed and dated by both sides, settles nearly every deposit argument before it starts.

  • Leaving the utility rate unstated

    Instead: Write the per-unit rate into the contract. Vague wording is what lets a landlord bill 8 baht for 4-baht electricity.

  • A three-year-plus lease left unregistered

    Instead: Register it at the Land Office, or your client's five-year security is really three.

  • English-only contracts

    Instead: Have a Thai version and state which language prevails. A Thai court will work from the Thai text regardless.

  • No named end date for the deposit return

    Instead: Put a deadline in days on the return. “Promptly” is not something a tenant can enforce.

Frequently asked questions

What must a Thai rental contract include?

The full details of both parties, a precise identification of the property, exact start and end dates, the rent and payment terms, the deposit and when it is returned, who pays which utilities and at what rate, the repair split, a signed condition inventory, notice periods, and which language version prevails. A lease of immovable property also has to be in writing to be enforceable by court action.

How much deposit can a landlord ask for in Thailand?

It depends on the landlord. A private owner renting one or two units can ask what they can negotiate, and the Bangkok norm is two months' deposit plus one month's rent in advance. A landlord renting five or more residential units falls under the 2018 residential leasing rules, which cap the deposit at one month's rent plus at most one month in advance.

Does a lease in Thailand need to be registered?

Only if it runs longer than three years. An unregistered lease over three years is enforceable for three years and no more, so a five-year lease left unregistered gives your client three years of security. Registration happens at the Land Office and costs 1% of the total rent plus 0.1% stamp duty. Thirty years is the maximum term.

Can a landlord charge more than the meter rate for electricity?

Not if they rent five or more residential units. Those landlords may only pass through electricity and water at the rate the provider charges them. Private landlords below that threshold are not bound by the same rule, which is why the contract should state the per-unit rate explicitly either way.

Can a tenant break a lease early in Thailand?

Under the 2018 rules, a tenant of a landlord with five or more units may end the lease on thirty days' written notice. Outside that, it comes down to what the contract says, so an early-termination clause is worth negotiating before signing rather than after.

Does the contract have to be in Thai?

For landlords covered by the 2018 rules, yes — the contract must be in Thai and the tenant must receive a signed copy. More generally, a Thai court works from the Thai text, so where there is a bilingual contract the agreement should state which language prevails.

This guide describes the general position under the Thai Civil and Commercial Code and the 2018 notification on residential leasing. It is not legal advice on a specific contract, and the rules that apply depend on the landlord's circumstances. Have a Thai lawyer review any lease of real value.
