สัญญาเช่าคอนโดสำหรับเจ้าของ: ข้อที่ต้องใส่ให้ครบ

You just closed on a condo at Life Asoke Hype near MRT Phetchaburi, and now you want to rent it out. You found a tenant through a Facebook group, agreed on 22,000 THB per month, and shook hands. Done, right? Not even close. Without a proper lease agreement, you are one burst pipe or one midnight disappearance away from a financial headache that could have been completely avoided. A solid condo lease agreement is not just paperwork. It is your insurance policy, your rulebook, and your legal shield all rolled into one document. Let me walk you through every clause that needs to be in there, based on years of watching landlords in Bangkok learn these lessons the hard way.

Why a Generic Template Will Cost You Money

Most first-time condo owners in Bangkok grab a one-page lease template off the internet, fill in the blanks, and call it a day. The problem is that those templates are usually translated from contracts designed for other countries, or they are so bare-bones that they leave massive gaps. Thai tenancy law, governed primarily by the Land Department regulations and the Civil and Commercial Code, has specific requirements that generic templates often miss entirely.

Here is a real scenario. A landlord at The Base Park West near BTS On Nut rented out a one-bedroom unit at 15,000 THB per month using a two-paragraph agreement. The tenant stopped paying after three months and refused to leave. Because the lease did not specify a proper eviction process, notice period, or penalty for breach, the landlord spent nearly six months and over 40,000 THB in legal costs to resolve the situation. A proper contract would have given clear remedies from day one.

According to a 2023 survey by CBRE Thailand, approximately 68% of individually owned condos in central Bangkok are rented out without professionally drafted lease agreements. That number should scare every landlord reading this.

The Must-Have Clauses Every Condo Lease Agreement Needs

Let me break down the essential clauses you should include. Skip any of these and you are leaving yourself exposed.

First, identification of parties. Full legal names, passport or Thai ID numbers, and current contact details for both landlord and tenant. If your tenant is an expat working near BTS Chong Nonsi, get their work permit number and a photocopy of their passport. This is basic, but you would be surprised how many landlords skip proper identification.

Second, property description. Include the full address, unit number, floor, building name, and the chanote (title deed) number. If you are renting out a unit at Ideo Q Siam Ratchathewi, do not just write "condo at Ratchathewi." Be specific. Include the size in square meters, the number of bedrooms, and any parking spaces included.

Third, rent amount and payment terms. State the exact monthly amount, the due date, the accepted payment methods, and the penalty for late payment. A common structure in Bangkok is a 1,000 to 2,000 THB late fee if rent is not received within 7 days of the due date. For context, average rents for a one-bedroom condo along the BTS Sukhumvit line currently range from 15,000 to 35,000 THB per month depending on the station and building age.

Fourth, security deposit and advance rent. Thai market standard is two months security deposit plus one month advance rent. State clearly the conditions under which the deposit can be deducted, and the timeline for returning it after move-out. The Thai Revenue Department considers rental income taxable, so keep proper records of all deposits received.

Clauses That Protect You From the Nightmare Scenarios

Beyond the basics, there are several clauses that separate a good lease from a great one. These are the ones that save you when things go sideways.

Maintenance and repair responsibilities. Spell out who pays for what. A general rule that works well in Bangkok condos is that the tenant covers repairs under 3,000 THB caused by normal use, while the landlord handles structural issues, air conditioning compressor failures, and appliance breakdowns from normal wear. A landlord at Lumpini Suite Sukhumvit 41 once ended up replacing a 45,000 THB water heater because the lease said nothing about maintenance responsibilities, even though the tenant had clearly misused the unit.

Subletting restrictions. Unless you explicitly prohibit it, a tenant could theoretically sublet your unit or list it on Airbnb. Many juristic offices in Bangkok condos already ban short-term rentals, but your lease should independently prohibit subletting without written landlord consent.

Early termination terms. Life happens. Expats get relocated, relationships end, jobs change. Your lease should specify a notice period for early termination, typically 30 to 60 days, and whether the tenant forfeits the deposit or pays a penalty. Without this clause, a tenant at Noble Revolve Ratchada near MRT Thailand Cultural Centre could walk out tomorrow and you would have limited recourse.

Inventory checklist as an appendix. Attach a detailed list of all furniture, appliances, and fixtures with their condition noted and photos taken. Both parties should sign this list. This is your evidence when the tenant claims the scratched dining table was already damaged when they moved in.

Comparing Lease Structures for Different Rental Situations

Not every rental situation calls for the same lease structure. Here is a comparison of common lease setups used by condo owners in Bangkok and when each one makes sense.

Lease Type	Typical Duration	Best For	Typical Rent Range (1-Bed)	Key Risk
Standard Fixed Term	12 months	Working professionals, expat couples	18,000 to 35,000 THB/month	Tenant leaves early without penalty clause
Short-Term Lease	3 to 6 months	Project-based expats, digital nomads	25,000 to 45,000 THB/month (premium)	Higher turnover, more wear and tear
Long-Term Lease	24 to 36 months	Families, embassy staff	15,000 to 30,000 THB/month (slight discount)	Rent locked below market if prices rise
Renewable Fixed Term	12 months with renewal option	Tenants unsure of long-term plans	18,000 to 35,000 THB/month	Must specify rent adjustment terms at renewal

The renewable fixed term option is increasingly popular in areas like Thong Lo and Ekkamai, where rents can fluctuate by 10 to 15% year over year. If you use this structure, always include a clause that specifies how much the rent can increase upon renewal, typically capped at 5 to 10% per year.

Legal Details That Bangkok Landlords Often Overlook

There are a few legal nuances specific to Thailand that many condo owners, especially first-timers, completely miss.

Stamp duty on lease agreements. Any lease with a term of three years or more must be registered with the Land Department and is subject to stamp duty at 0.1% of the total rent for the entire lease period. Even for leases under three years, stamping your agreement makes it admissible as evidence in court. The cost is minimal, often just a few hundred baht, but the legal protection is significant.

Withholding tax on rental income. If your tenant is a company paying rent on behalf of an employee, they are required to withhold 5% of the monthly rent and remit it to the Revenue Department. Your lease should specify whether the stated rent is before or after withholding tax. A landlord with a unit at Ashton Asoke near MRT Sukhumvit once discovered a 30,000 THB shortfall at tax time because the lease was ambiguous about who bears the withholding tax burden.

Governing law and dispute resolution. State that the agreement is governed by Thai law and specify whether disputes should go through Thai courts or arbitration. For most Bangkok condo leases in the 15,000 to 50,000 THB per month range, court is the practical option since arbitration can be disproportionately expensive.

Getting the Language Right

If your tenant is a foreigner, draft the lease in both Thai and English, but specify which version prevails in case of any discrepancy. Most lawyers in Bangkok recommend that the Thai version be the governing text since Thai courts will refer to the Thai language version if a dispute ever reaches litigation.

Consider a scenario at Rhythm Sukhumvit 36-38 near BTS Thong Lo. A Japanese tenant and a Thai landlord signed an English-only lease. When a dispute arose about utility payments, the court requested a certified Thai translation, which delayed proceedings by two months and cost the landlord an additional 15,000 THB in translation and legal fees. Having a bilingual contract from the start would have avoided this entirely.

Also include a clause about communication methods. Specify that official notices must be sent via registered mail or email to documented addresses. LINE messages might be how Bangkok works in practice, but they are harder to use as formal evidence compared to registered mail or email with read receipts.

A well-drafted lease agreement is not about being aggressive or mistrustful toward your tenant. It is about creating clarity so that both sides know exactly where they stand. The best landlord-tenant relationships in Bangkok are built on clear expectations, and those expectations live in your lease. Take the time to get every clause right, have a qualified Thai lawyer review the document at least once, and treat your lease as the foundation of a professional relationship.
