Rental Security Deposit in Thailand: When It Must Be Returned, What Can Be Deducted, and the Refund Letter

The security deposit does not belong to the landlord. It is the tenant's money, to be returned when the lease ends, with deductions allowed only for items backed by a genuine reason. And the single best document for preventing disputes is a one-page deposit refund letter that both sides sign, so everyone agrees on the same numbers.

This article is written for both sides: tenants waiting for their deposit back, and landlords who want to close out a lease cleanly with no dispute left hanging.

TL;DR: Residential rental businesses that fall under the Contract Committee Notification must return the tenant's security deposit within the period prescribed by law after the lease ends and the room inspection is complete. Deductions are allowed only for unpaid rent, unpaid utilities, and damage beyond normal wear and tear, backed by evidence. Deductions for peeling paint, small nail holes, or routine cleaning are not allowed. Tenants who don't get their money back can complain to the Thailand Consumer Council free of charge. On the landlord side, a deposit refund letter that itemizes every deduction and is signed by the tenant is the document that closes a lease with no dispute coming back later.

What the Law Says: Who Must Refund, and Within How Long

Landlords operating a residential rental business that falls under the Contract Committee Notification must return the tenant's security deposit within the period prescribed by law, counted from the end of the lease and the completion of the room inspection.

One thing this article owes its readers honestly: an individual owner renting out just a few units may not qualify as a business covered by this Notification. In that case, the lease agreement signed at the start sets the rules for the deposit instead — which makes it all the more important to write the deposit clauses clearly from day one in your condo lease agreement.

What Can Be Deducted — and What Can't

Deductions are allowed only for unpaid rent, unpaid utility bills, and damage beyond normal wear and tear, backed by evidence. They are not allowed for paint that has faded over time, small nail holes, or routine cleaning — all of which count as normal wear and tear.

• Deductible: rent still owed, unpaid water and electricity bills, and damage beyond normal use — such as broken glass or seriously damaged flooring — supported by evidence like photos or repair quotations
• Not deductible: wall paint that has faded or peeled with age, small nail holes from ordinary picture-hanging, routine cleaning costs, and forfeiting the deposit because the tenant moved out early — unless a contract clause explicitly provided for it in advance

In one case handled by the Thailand Consumer Council, a landlord tried to keep a ฿16,000 deposit because the tenant moved out before the end of the lease. On review, the lease contained no clause supporting forfeiture in that situation — so the tenant recovered the full amount. The principle is simple: no supporting clause = no right to forfeit.

Tenants: What Can You Do If You Don't Get Your Money Back?

Step one is a written demand letter. If there is still no response, you can complain to a consumer protection body free of charge, before considering civil action.

Landlords: Why You Should Issue a Deposit Refund Letter

Every tenant question above is a dispute a landlord can prevent in advance. A deposit refund letter that itemizes every deduction and is signed by the tenant closes the lease with no argument coming back later.

For real estate agents, professionalism at the move-out inspection is what builds reputation and referrals. Read about the step before this one in the lease termination notice guide, and the original deposit clauses in the condo lease agreement.

What the Deposit Refund Letter Must Contain

A complete deposit refund letter includes: the original deposit amount, each deduction with supporting evidence, the net amount refunded, the method and date of payment, a reference to the room inspection, and both parties' signatures.

• The original deposit amount placed by the tenant at the start
• Each deduction, itemized — with supporting evidence such as photos or repair quotations
• The net refund amount after all deductions
• The method and date of payment — e.g. bank transfer
• A reference to the room inspection carried out together
• Both parties' signatures — confirming they agree on the same items and the same numbers

Do It Online: A Ready-Made Template

A deposit refund letter template is ready to use in the Jabmue gallery — a form where you fill in the amounts and deductions directly, get a bilingual PDF, and send it to the tenant for online signature immediately.

This is especially convenient when the tenant has already moved away — back to their home country or to another province, which happens all the time. Electronic signatures are recognized under the Electronic Transactions Act B.E. 2544 (2001), and the recorded audit trail strengthens the evidentiary weight of the document — it is not an absolute, 100% legal guarantee.

Frequently Asked Questions

Within how many days must the deposit be returned?

The law sets a refund period for landlords covered by the Contract Committee Notification, but the exact period should be checked with a legal advisor or the relevant authority first, since the rules are updated from time to time.

Can the landlord deduct for repainting or cleaning?

Not if it is normal wear and tear — such as paint that has faded over time or routine cleaning. Only damage beyond normal use, backed by evidence, can be deducted.

The landlord won't refund — can I sue?

Start by complaining to the Thailand Consumer Council, which is free of charge, before considering civil action. For the detailed steps, consult a legal advisor case by case.

An owner renting out a single unit — does the Notification apply?

An individual owner renting out only a few units may not qualify as a business covered by the Notification. In that case, the lease agreement signed at the start sets the rules instead.

Can the deposit refund letter be signed online?

Yes, under the Electronic Transactions Act B.E. 2544 (2001), provided the signing method is reliable and verifiable after the fact.

Summary

The deposit must be returned within the period prescribed by law; only items backed by a genuine reason and evidence can be deducted; and a deposit refund letter signed by both sides is the document that closes a lease with no dispute coming back later.
