Types of Lease Agreements

Lease Registration

When Registration Is Required

Leases exceeding 3 years must be registered at the local Land Office (CCC §538):

• Registration fee is 1.1% of total rent for the full lease term
• Unregistered leases over 3 years are enforceable for only the first 3 years
• Registered leases bind subsequent property owners if ownership is transferred

Maximum Lease Term

• The statutory maximum lease term is 30 years (CCC §540)
• Automatic renewal clauses designed to circumvent the 30-year limit may not be enforceable

Mandatory Lease Content (Business Landlords)

Business landlord leases must include:

1. Full names and addresses of landlord and tenant
2. Property description — location, size, characteristics
3. Move-in condition report with photographs (attached to the lease)
4. Lease term — start and end dates
5. Rent amount and payment schedule
6. Security deposit — amount and return conditions
7. Utility rates — electricity, water, common area charges
8. Termination conditions for both parties
9. Language — must be in Thai with legible font

Prohibited Lease Clauses

Under the OCPB Notification, the following clauses are deemed unfair:

• Clauses allowing the landlord to unilaterally increase rent
• Clauses exempting the landlord from liability for breach of contract
• Clauses granting the landlord the right to seize tenant property
• Clauses forfeiting the security deposit without actual damage
• Clauses restricting the tenant's right to early termination beyond what the law permits
• Clauses allowing the landlord to enter and inspect without notice

Tenant's Right to Early Termination

Tenants in fixed-term leases may terminate early if:

• They have occupied the property for at least 50% of the lease term
• They provide 30 days' written notice
• They have no outstanding rent or service charges
• They have settled all financial obligations

Best Practices for Landlords

1. Always use written agreements — Even for short-term leases
2. Register leases over 3 years — Otherwise they are enforceable for only 3 years
3. Prepare bilingual contracts — Thai and English for foreign tenants
4. Review prohibited clauses — Before presenting to tenants for signing
5. Keep copies — Both parties should have executed copies with all attachments
