Commercial leases in Thailand, primarily governed by the Civil and Commercial Code (effective 1 April 1929) and supplemented by the Act on the Lease of Immovable Property for Commercial and Industrial Purposes B.E. 2542, offer significantly more contractual freedom than residential leases.
Types of Commercial Leases
All lease types are freely negotiated and must be clearly specified in the contract.
Registration Requirements
Failure to register a lease over 3 years means it is enforceable for only the first 3 years (Civil and Commercial Code, Section 538).
Essential Lease Terms
A well-drafted commercial lease should include:
- Parties — Names, addresses, tax identification numbers
- Property description — Location, size, permitted use
- Rent and escalation mechanisms — Amount, schedule, adjustment conditions
- Expense allocation — NNN or Gross, clearly specified
- Security deposit — Amount and return conditions
- Term and renewal options — Rights to extend
- Fit-out and modification rights — Scope of permitted alterations
- Termination conditions — Grounds, process, compensation
- Property surrender — Required condition at lease end, removal obligations
- Dispute resolution — Jurisdiction of the Civil or Provincial Court, or arbitration (e.g., TAI or THAC)
Best Practices for Landlords
- Engage an attorney to draft the lease — Commercial agreements are complex
- Register long-term leases — To ensure enforceability for the full term
- Detail NNN terms thoroughly — Prevents expense disputes
- Include an arbitration clause — Often faster than court litigation
