A Bangkok condominium contract is not a formality to review after paying a substantial deposit. It is the document that identifies the property, controls the payment sequence and allocates risk if transfer, handover or performance does not proceed as expected. Foreign buyers should understand the commercial effect of the clauses before signing.
This guide is a practical reading framework, not legal advice. Contract wording, transaction structure and facts differ. A buyer should appoint an independent Thai lawyer who acts for the buyer, can review the Thai-language documents and can explain how the proposed terms apply to the exact deal.
Confirm the parties and signing authority
The seller’s name should match the ownership or development records relevant to the transaction. If a company, representative, attorney or authorised signatory is involved, ask the lawyer to verify capacity and supporting authority. Names, identification details and addresses should be consistent across the reservation, agreement, invoices and payment instructions.
A buyer should also decide who will own the unit before the contract is finalised. Changing from an individual to another person or entity later may require consent, additional documents, cost or a new agreement. Do not assume a nomination or assignment is automatically permitted.
Identify the property precisely
The contract should clearly identify the condominium, unit number or intended unit, floor, approximate area and any parking or accessory rights included. For a new development, plans, specifications, furniture schedules and promised finishes should be attached or incorporated in a way the lawyer considers effective.
For a completed resale unit, compare the contract description with the title deed, physical inspection and inventory. Clarify which furniture, appliances, access cards, remotes and fixtures remain. Marketing images and verbal assurances are difficult to rely on when they are absent from the signed transaction record.
Address foreign ownership eligibility
Foreign buyers commonly focus on the statutory foreign-ownership limit and the evidence required for qualifying inward remittance. The contract should be reviewed for what happens if the unit cannot be transferred to the buyer as intended, which party must obtain relevant condominium documentation and when that evidence must be available.
Do not rely on a casual statement that foreign quota is available. Ask for current written confirmation at the appropriate stage and let the lawyer check the ownership route, funds documentation and Land Office requirements. The payment path should be planned with the receiving bank before money is sent.
Map every payment and condition
Create a schedule showing the reservation amount, contract deposit, instalments, balance at transfer and any retention or adjustment. Each entry should show the amount or calculation, due date, recipient and condition that triggers payment. Check whether tax, bank or currency movements could cause a shortfall.
Pay particular attention to refund language. A clause may treat one payment differently from another or make a refund dependent on a narrow event. Ask what happens if legal due diligence reveals a problem, financing is unavailable, foreign ownership eligibility fails, the seller misses a condition or the unit materially differs from the agreed specification.
Understand default and termination
Default clauses should not be read only as penalties for late buyer payment. Compare the remedies available to both sides, notice requirements, cure periods, interest, forfeiture, refund timing and the right to terminate. Identify which breaches are material and whether the consequences are proportionate to the risk.
Long-stop dates matter in off-plan transactions. A projected completion date may not be the same as an enforceable deadline. Ask how extensions operate, what notice must be given and what options the buyer has after the final permitted period. For resale, clarify what happens if either side is not ready at the agreed transfer appointment.
Allocate transfer costs and adjustments
The agreement should say who pays transfer fees, taxes, duties, withholding amounts, juristic charges and professional costs. The actual legal incidence and negotiated allocation are separate questions, so have the lawyer and tax adviser explain both. Avoid using an informal percentage shortcut without knowing what it covers.
For a resale, common fees, utilities, rent, deposits and other property outgoings may need to be apportioned at completion. Confirm how arrears are cleared and which certificates or receipts the seller must provide. For a new unit, identify any sinking fund, advance common fee, meter, connection or handover charges.
Set a workable inspection and handover process
New-build contracts should be checked for inspection rights, notice, defect reporting, rectification and the relationship between handover and transfer. A short inspection window can be difficult for an overseas buyer, so plan representation early. Technical inspection is different from legal review and may require a qualified specialist.
For resale, record condition close to transfer and agree how vacant possession, keys, access devices and the signed inventory will be delivered. If a tenant remains, the transaction requires additional review of the lease, deposit, rent, notices and the buyer’s intended use.
Check language, attachments and the entire agreement
Where Thai and English versions are provided, ask which text prevails and obtain advice on the Thai wording. A convenient translation helps understanding but does not replace review of the operative document. Version control is essential: every page, schedule and amendment should belong to the same agreed set.
Entire-agreement and non-reliance clauses can make it especially important to capture promises in writing. If a view, furniture package, rental arrangement, completion feature or repair influenced the purchase, ask the lawyer how it should appear in the contract rather than relying on messages or a brochure.
