Contract Law in Thailand is a fundamental area of the legal system that governs how agreements are made, interpreted, and enforced. Whether you’re a business owner, service provider, supplier, or consumer, almost every commercial or personal transaction you engage in is governed by a contract. Thailand’s contract law is primarily derived from the Civil and Commercial Code, and it outlines the rules for forming valid contracts, interpreting their terms, and resolving disputes when obligations are breached.
Because contracts are legally binding documents, any misunderstanding or poorly written clause can lead to serious consequences. That’s why it’s critical to have clear, enforceable contracts—especially in a cross-cultural or multilingual business environment like Thailand’s. Working with a qualified contract lawyer helps you ensure your rights are protected, risks are minimized, and your business relationships remain secure.
What Is Covered Under Contract Law in Thailand?
Contract lawyers in Thailand advise clients on a broad range of legal matters related to the drafting, negotiation, review, and enforcement of contracts. They ensure that contracts are both legally sound and commercially practical.
Here are the main areas they typically cover:
Contract Formation and Legal Validity
A contract is legally valid in Thailand when it meets essential criteria: mutual consent, lawful purpose, and capable parties. Lawyers help:
- Draft contracts that meet Thai legal standards
- Ensure terms reflect true intent of the parties
- Avoid ambiguities and unenforceable clauses
While many verbal agreements are enforceable in Thailand, written contracts offer significantly more clarity, security, and legal protection.
Types of Contracts Under Thai Law
Under Contract Law in Thailand, a wide range of agreements may be used in both personal and commercial contexts. Below are some of the most common and important contract types that lawyers frequently draft, review, or enforce:
- Sales and service contracts – Agreements for the purchase of goods or the provision of services, common in both B2B and B2C transactions.
- Lease agreements – Contracts for renting property, vehicles, or equipment, including residential and commercial leases.
- Loan and financing agreements – Used in personal or business lending, often including terms on interest, repayment, and collateral.
- Franchise and distribution agreements – Define the rights and obligations between franchisors and franchisees, or suppliers and distributors.
- Licensing agreements – Cover the use of intellectual property, such as trademarks, patents, or software, by third parties.
- Confidentiality and non-disclosure agreements (NDAs) – Protect confidential information shared between parties during negotiations or business relationships.
- Non-compete agreements – Restrict a party (often an employee or business partner) from competing within a defined time or geography.
- Contract farming agreements – Define the relationship between farmers and agribusinesses; common in Thailand’s agricultural sector, as well as, cannabis.
- Employment and consultancy agreements – Govern relationships between employers and employees, or companies and independent consultants.
- Joint venture and partnership agreements – Outline how two or more parties collaborate in a shared business or investment, including roles and profit-sharing.
- Shareholder agreements – Set out rules for ownership, voting rights, exits, and share transfers in limited companies.
- Prenuptial agreements – Common in Thailand, especially in cross-national marriages.
Many of these overlap with intellectual property or labor issues. For example, NDAs, licensing terms, and service-level agreements are often used in Intellectual Property Law. In addition, special rules may apply to real estate contracts, employment agreements, and consumer-related transactions. Many contracts are also closely connected business structuring and corporate governance. For related guidance, see our page on Business & Corporate Law in Thailand.
Review and Risk Assessment
Contract lawyers conduct thorough legal reviews of existing or proposed agreements to:
- Identify legal loopholes and liabilities
- Assess compliance with Thai law
- Recommend changes to protect client interests
This is particularly important when dealing with foreign-language contracts or contracts governed by foreign law but enforced in Thailand.
Contract Enforcement and Remedies
If one party breaches a contract, Thai law provides remedies such as:
- Specific performance (forcing compliance with the contract)
- Termination of the contract
- Compensation for damages
- Penalty clauses, if pre-agreed
Lawyers assist with negotiation, formal notices, and legal actions to enforce contractual rights or resolve disputes.
Cross-Border Contracts and International Agreements
Thailand is a hub for regional trade and investment, so international contracts are common. Lawyers advise on:
- Jurisdiction clauses
- Governing law
- Language clauses
- Arbitration vs. court litigation
This helps avoid legal surprises when disputes cross borders.
