Review of contracts in Thailand
Contract review before deposit catches foreign quota gaps, weak lease renewals, and penalty clauses that agents gloss over. Reservation agreements, sale and purchase agreements, and lease instruments each carry different legal risks for expat buyers.
At Thai Visa Centre in Bangkok, we help expats coordinate lawyer referrals before signing property documents. This guide explains what to review and when. See our contract review checklist and property hub.
Early lawyer review is cheaper than dispute after payment.
Land Office registers Thai controlling language regardless of English draft.
Reservation, SPA, lease, and addenda each need review.
Developer or agent templates protect seller interests first.
Property contracts to review
Each document type carries distinct risks. Do not sign a bundle without clause-by-clause review.
| Document | Review focus |
|---|---|
| Reservation agreement | Refundability, exclusivity, and deposit cap before due diligence |
| Sale and Purchase Agreement | Completion date, default remedies, fee split, and penalty clauses |
| Lease agreement | Term, renewal, assignment, prepaid rent, and registration duty |
| Developer off-plan contract | Escrow, construction milestones, and delay compensation |
| Juristic person forms | Foreign quota confirmation and transfer consent wording |
High-risk clauses agents skip
Lawyers flag these during review before you bind yourself at the Department of Lands or in private contract.
| Clause type | Risk if unchecked |
|---|---|
| Foreign quota condition | Deposit lost if quota unavailable with no refund right |
| Weak renewal option | Verbal promise not enforceable at lease end |
| Seller-friendly default | Buyer forfeits deposit on minor technical breach |
| Prepaid rent lump sum | No refund if developer fails before registration |
| Assignment restriction | Blocks resale of leasehold interest later |
Contract review workflow
Allow several business days for thorough review. Rush signing at showroom is how disputes start.
Send draft to lawyer
Provide reservation, SPA, lease, and marketing materials for comparison.
Compare Thai and English
Verify Thai controlling text matches English summary you rely on.
Negotiate amendments
Lawyer proposes redlines on quota, default, completion, and fees.
Confirm registration path
Contract must align with what Land Office will register.
Sign only after report
Written diligence and contract memo before deposit or binding SPA.
Retain signed copies
Keep registered instruments and all addenda for resale or dispute.
What lawyers check in SPA review
Standard review covers commercial terms and registrability under Thai law.
- Seller identity matches title deed owner
- Purchase price and payment schedule with FET milestones
- Completion date and snagging or defect remedies
- Transfer fee and tax allocation between parties
- Default and termination with deposit refund rules
- Foreign quota condition precedent where applicable
Marketing is not the contract
Brochures and showroom statements rarely bind unless written into the SPA or lease. See our five-point contract checklist for the top clauses to verify.
Common mistakes foreigners make
Buyers who skip review often discover these problems after deposit is paid.
- Signing reservation before title search and quota confirmation.
- Trusting agent verbal summary instead of Thai controlling text.
- Accepting non-refundable deposit without legal condition precedent.
- Missing lease renewal mechanics in villa leasehold packages.
- Using developer in-house review as sole contract advice.
Frequently asked questions
General answers on property contract review in Thailand. Instruct a lawyer for your specific documents.
Q:Does this replace a property lawyer?
A:No. This guide orients you. Licensed counsel must review your actual contract.
Q:When should I review the contract?
A:Before any deposit or reservation fee. After payment, leverage to negotiate drops.
Q:Is English version enough?
A:Thai text controls at Land Office. Bilingual review compares both versions.
Q:How long does review take?
A:Straightforward Bangkok condo resales often need three to five business days. Off-plan villas, mixed Thai-English drafts, or leasehold structures take longer. Plan review before any non-refundable payment deadline in the reservation letter.
Q:What does contract review cost?
A:Often lower tier than full diligence if title already verified separately.
Q:Can I negotiate developer template?
A:Yes. Standard templates are seller-drafted and negotiable before signing.
Q:What if agent pressures quick signing?
A:Walk away. Pressure to skip review is a red flag on the deal itself.
Q:Should lease and SPA be reviewed together?
A:Yes for villa packages where lease, superficies, and SPA interact.
