Business Contracts in Thailand

Use the legal name, registration details and address of the person or entity actually taking the obligation. A brand, trading name or project name may not identify the contracting party. Check whether you are dealing with the parent, subsidiary, branch or an individual.

Obtain current authority evidence and check the registered signing conditions, any required joint signature and any power of attorney. DBD public data helps identify an entity but does not guarantee performance, ownership of an asset or the authority of every employee. Confirm the bank beneficiary independently before making a material payment.

Specify what will be supplied, quantities or milestones, standards, location, timetable and dependencies. List exclusions and customer responsibilities. For services, name the outputs and acceptance process rather than relying only on phrases such as “best efforts” or “complete support.”

Agree who checks delivery, how defects are reported, how much time is allowed to respond and what remedy is available. Attach the actual specification and identify which document takes priority if a proposal, purchase order and main agreement conflict.

State the currency, price basis, invoicing details, due date and any deposit or retention. Explain whether VAT is included or additional, and have withholding or cross-border tax issues reviewed. A contract’s label cannot by itself determine the correct tax treatment.

Tie payments to clear events and evidence. Address expenses, exchange-rate exposure, late payment, disputed amounts, refunds and the consequences of a cancelled order. If a guarantee or security is important, have its form and enforceability reviewed rather than relying on an informal promise.

Use a change process that records the request, revised scope, price, timetable and approval. Identify who can approve changes for each side. A friendly message from someone without authority can create a dispute about whether extra work was authorised.

Address delays, dependencies, service interruption and exceptional events. Require prompt notification and realistic mitigation steps. Clarify whether subcontracting is allowed, who remains accountable and what access subcontractors may have to confidential information, systems or premises.

Separate material that already exists from new work created for the project. Agree who owns or licenses deliverables, when rights pass, which uses are allowed and whether third-party components impose restrictions. Payment for a project does not answer every intellectual-property question without reviewing the applicable terms and law.

Define confidential information, permitted recipients, security, return or deletion and legal disclosure exceptions. If personal data is involved, assess the parties’ controller or processor roles, lawful uses, security, incident cooperation and any overseas transfer. Do not treat a generic confidentiality clause as a complete data-protection arrangement.

Have exclusions, caps, indemnities, insurance and remedies reviewed against the actual risks and applicable mandatory rules. A liability limit is less useful if it excludes the loss that is most likely or is inconsistent with another clause.

Specify duration, renewal, termination grounds, notice, cure periods and what happens afterwards. Cover outstanding payment, unfinished work, customer records, access, transition assistance and survival of obligations. Record notice addresses and permitted delivery methods so a future notice can be served correctly.

Some transactions have specific writing, witnessing, registration or other formal requirements. Ask counsel about the exact contract, assets and parties. Do not assume that notarisation is universally required, or that a signed English document removes every local formality.

Where two languages are used, have both reviewed and identify the intended controlling version, while considering how a Thai authority or court will handle translations. Avoid signing a version you do not understand or relying on a verbal explanation that differs from the text.

Stamp duty applies to specified instruments rather than every business transaction. Check whether the instrument is chargeable, who must pay, the correct method and deadline, including electronic instruments. Keep the official payment evidence; do not simply attach an arbitrary stamp value to every agreement.

ETDA explains electronic contracts in terms of legal requirements, identifying the parties, showing intention and securely retaining evidence. The appropriate signing method depends on the transaction and its risk; an image of a signature is not automatically a complete execution process.

Confirm that the contract type and any separate formalities permit the proposed method. Preserve the final version, attachments, identity and authority checks, signing trail and timestamps where available. Make sure the business can retrieve readable evidence after a platform or provider changes.

Review governing law, courts or arbitration, any institution and rules, seat, language and escalation steps. Arbitration and mediation perform different functions. A mediation clause should not accidentally conflict with the mechanism needed for a binding decision if no agreement is reached.

Assess cost, location of assets, enforceability and the value of the contract before copying an overseas template. Do not assume a foreign judgment and an arbitral award follow the same enforcement route. Ask counsel to check deadlines, urgent relief and cross-border consequences for the actual deal.

Store one authoritative executed version with every schedule, amendment and authority document. Give the delivery, finance and management teams a short obligations list: milestones, approvals, invoices, notices and expiry dates. Limit access to sensitive details appropriately.

Keep evidence of delivery, acceptance, changes and payment. If performance fails, preserve the original records and obtain advice before terminating, withholding money or making public accusations. A contract is an operating record, not a file that becomes useful only after a dispute.
