Tenant Not Paying Rent? What You Can (and Can't) Legally Do

Published May 28, 2026 · 9 min read

Two months overdue, your messages read but ignored, and part of you just wants to cut the power to make a point — while another part is afraid of breaking the law. Almost every Thai dorm owner has been here, and no, you're not being too soft. This is the full picture: what you can do, what gets you counter-sued, the actually-legal sequence, and how to stop it happening again — every point backed by real Thai law.

TL;DR (30-second read)

Don't cut power/water, lock the room, or remove belongings yourself — even if rent really is overdue. It's illegal and the tenant can counter-sue (confirmed by Supreme Court ruling)
Legal sequence: written notice to pay within 15 days → contract termination → file for eviction (Civil & Commercial Code Section 560)
Eviction takes 6–12 months on average and costs ฿15,000–50,000 — prevention is far cheaper
You may chase the debt, but you can't threaten, shame, or tell others about it (Debt Collection Act 2015)
Prevent 90% of cases with a tight contract + security deposit + automatic reminders from day one

4 things you must NEVER do (even when rent really is overdue)

Many owners do these because they think 'it's my room, why can't I?' — but the law sees the tenant as having a possessory right to the room. Interfering with that possession yourself is a violation, and exposes you to both criminal and civil counter-suits:

Cut water/electricity to force them out

Violates the right of habitation and may amount to coercion. Only allowed after the lease has lawfully ended or a court has ordered eviction.

Change the lock / bolt the door / block room access

Cuts off the tenant's access to their property — this is criminal trespass (Penal Code Section 362). A Supreme Court ruling confirms it.

Remove / seize / hold belongings as 'collateral'

Even with genuine arrears, you can't remove belongings yourself — it must go through court enforcement, or you risk theft / property-damage charges.

Shame them / post a notice on the door / tell other tenants

Violates the Debt Collection Act 2015 (disclosing the debt to outsiders), and may also be defamation.

⚠️ Simple rule: until you've lawfully terminated the contract or a court has ordered eviction, the room is still the tenant's to possess — you can't take matters into your own hands.

The legal 5-step sequence (under Section 560)

It sounds bureaucratic, but you just follow the order. The single most important thing is to keep evidence at every step — if it reaches court, evidence decides who wins:

1
Verbal / message reminder, politely
First day overdue
Start with a LINE/phone reminder stating the amount owed + due date. Keep the chat as evidence — many cases end right here, some tenants simply forgot.
2
Written notice to pay (in writing)
After ~7 days overdue
State the amount owed + give 'at least 15 days' to pay, as the law requires. Send by registered mail with return receipt or EMS, and keep the receipt.
3
Written contract termination
After the 15 days
If 15 days pass with no payment, send a formal termination notice stating the end date + requesting return of the room. Send the same way as step 2.
4
File for eviction at court
When they won't leave
If they still won't leave, file at the District Court (claim ≤ ฿300,000) or Provincial Court. Documents: lease, evidence of arrears, all letters — the whole case averages 6–12 months and ฿15,000–50,000.
5
Enforcement + deduct from deposit
After the court order
Once the court orders eviction, the execution officer can act (including removing belongings). Afterward, deduct from the deposit for actual arrears + documented damages — any excess must be returned.

💡 Tip: The payment notice and termination can be combined into one letter (pay within 15 days or the lease is terminated) to save time — but if you're unsure of the wording, one consult with a lawyer beats writing it wrong.

How to chase rent without breaking the Debt Collection Act 2015

Chasing rent is debt collection, so it falls under the Debt Collection Act 2015 — you can chase, but there's a line you can't cross, because crossing it turns you from creditor into offender:

✅ Allowed

Contact the tenant directly at reasonable hours (weekdays ~08:00–20:00)
State the amount owed, due date, and any late fee written into the contract
Send a notice in a sealed envelope that doesn't say 'debt collection' on the outside
Keep evidence of every contact (chats, postal receipts)

❌ Forbidden

Threaten, use force, or use insulting / abusive language
Tell or shame others about the debt (friends, parents, other tenants)
Post a notice on the door, or send a postcard/envelope visibly marked as debt collection
Impersonate a lawyer, court, or government official to intimidate

Prevention — 10x cheaper than fixing it later

Almost every arrears case that escalates to court was preventable at the signing table. Here's what owners who 'almost never get stiffed' all do:

#1Always take a security deposit before move-in (max 1 month by law)

The deposit is your first-month buffer — people who plan to skip out often won't pay it.

#2Written lease with a clear late-fee clause

No contract = a hard court case. A stated late fee tells tenants paying late has a cost.

#3Issue invoices on the same day every month, early

Late invoice = money already spent = late payment. Consistency builds payment discipline.

#4Set automatic reminders on day 5 and day 10

Polite, consistent reminders genuinely reduce arrears — without you having to chase.

#5Let them pay via PromptPay QR + a LINE link

The easier it is to pay, the faster they pay — it kills the 'I haven't had time' excuse.

You're not alone — stories from the owners' circle

The three situations below are composites of what owners face most often (not any one real person) — in case you're in the middle of the same thing and need to know others have come through it:

The most common case

A tenant paid on time for 8 months, then went silent in month 9 — messages read, no reply.

"Part of me feels for them, maybe they lost their job. Part of me fears getting played. Be kind or be firm?"

Usually it's a temporary money problem. Try talking directly, offer an installment plan — but put it in writing, and start the 15-day clock in parallel in case the plan falls through.

The most painful case

Three months overdue, the tenant moved out in the night, left a room full of broken stuff, unreachable.

"I just want to dump it all and re-rent. Why wait? They already ran."

Stay calm — photograph everything as evidence first, send a termination notice to the address on the lease, then sue (courts usually evict fast when the tenant is absent). You can deduct the deposit, but don't remove belongings before the court order.

The caught-in-time case

A new, hot-headed owner cut the power on a tenant 2 months overdue. The tenant filmed it, threatening to report them.

"I did it before I knew it was illegal — now I'm the one at risk of being sued."

Restore the power immediately, apologize, and get back onto the proper process. Taking one step back now beats fighting a criminal case where you're the one in the wrong.

The shared lesson across all three: don't decide while angry. Follow the steps, keep evidence, and let the system work — you'll be safer and it'll end faster, every time.

FAQ

Tenant is 1 month overdue — can I file for eviction right away?

Not immediately — Section 560 requires a written notice giving at least 15 days to pay first. Only if they still don't pay can you terminate and sue. Filing without prior notice can get the case dismissed.

Really can't cut power/water, even though they didn't pay the utility bill?

No — even if utilities are unpaid, cutting them to force a move-out violates the right of habitation and can be a criminal offense. Use the termination / court route instead.

1 month's deposit doesn't cover 3 months of arrears. What now?

Deduct what the deposit covers, and claim the rest in the same lawsuit (arrears + damages + contractual late fees). The court will order repayment, but actually recovering it depends on whether the tenant has assets to enforce against.

Tenant ran off, room is locked — can I open it to look?

You shouldn't open it yourself before the lease ends or is lawfully terminated. Send a termination notice to the address on the lease first. For genuine emergencies (e.g. a leak), have a witness and photograph every step.

My dorm has fewer than 5 rooms — do CPB rules apply?

The CPB Notice 2018 (controlled lease contracts) applies to landlords with 5+ rooms/units. Smaller dorms aren't covered by it — but Section 560 and the Debt Collection Act apply to every size.

Can I write the notice/termination myself, or do I need a lawyer?

You can write it yourself — just state the amount owed, a deadline (≥15 days), and send it with proof. But if it's heading to court, one lawyer consult keeps your documents tight and your case intact — worth it over risking a mistake.
