Thai Lease Red-Flag Scanner: Is Your Rental Contract Fair?
Paste your Thai rental or condo lease agreement below. Our AI checks it against the Thai Civil and Commercial Code (ประมวลกฎหมายแพ่งและพาณิชย์) and the 2018 Residential Rental Controlled Contract, and flags anything risky in under a minute — deposit traps, illegal eviction clauses, unfair repair costs, and more.
What this Thai lease checker looks for
Expats and Thai tenants renting a condo, apartment, or house in Bangkok, Phuket, Pattaya, or Chiang Mai often sign a lease agreement (สัญญาเช่าบ้าน / สัญญาเช่าคอนโด) without knowing which clauses are actually enforceable under Thai law. This free tool checks five common trouble spots in Thai rental contracts:
- Deposit & advance rent (เงินประกันการเช่า) — is the security deposit within the legal 1-month cap, and can it really be refunded?
- Termination & eviction (การบอกเลิกสัญญาเช่า) — can your landlord really change the locks or cut your electricity for late rent?
- Early-exit penalties (ค่าปรับยกเลิกสัญญาก่อนกำหนด) — is a "no early termination" clause actually legal?
- Repairs & maintenance (ค่าซ่อมแซม) — who legally pays for aircon, plumbing, and normal wear and tear?
- Subletting & sale of the property (การเช่าช่วงและการขายทรัพย์สิน) — what happens to your lease if the owner sells the unit?
Every red flag comes with the exact Civil and Commercial Code section or Ministerial Notification behind it — the same citations a Thai lawyer would use — so you can negotiate from a position of knowledge, not guesswork. ทนายความไทยตรวจสอบสัญญาเช่าให้คุณฟรีในเบื้องต้น ก่อนตัดสินใจเซ็นสัญญา

Book a consultation with a lawyer →Is a Thai lease agreement legally binding without a lawyer?
Yes — a written Thai lease is enforceable once signed, which is exactly why it's worth checking before you sign, not after a dispute starts. This tool gives you an automated first read; it is not a substitute for a lawyer reviewing your specific lease. เครื่องมือนี้ไม่ใช่คำแนะนำทางกฎหมาย หากต้องการความเห็นจากทนายความโดยตรง สามารถนัดหมายปรึกษากับทนายความของเราได้
ThaiLawOnline.com has practiced Thai law since 2006, including landlord-tenant disputes, lease drafting, and Supreme Court (ศาลฎีกา) precedent on rental agreements. If this scanner finds high-risk clauses in your lease, book a consultation before you sign or renew.
