1. About สัญญา Law in Thailand

สัญญา, or contract law, in Thailand governs how agreements between people and businesses are formed, performed and enforced. The Thai Civil and Commercial Code is the primary source of rules for obligations and contracts. It covers offer and acceptance, capacity, legality of purpose, and the consequences of breach.

In practice, Thai contract law allows both written and spoken agreements, but certain contracts must be in writing or formally registered to be enforceable. For example, sales of immovable property typically require a written contract and proper registration. The law also addresses issues like misrepresentation, mistake, and duress to protect the parties' voluntary consent.

Thailand increasingly recognizes electronic contracts and digital records. The Electronic Transactions Act supports electronic signatures and the validity of electronic contracts, making online agreements enforceable when properly executed.

2. Why You May Need a Lawyer

Navigating สัญญา issues in Thailand often requires tailored advice to fit your context. Here are concrete scenarios where engaging a solicitor or attorney is wise.

• Drafting a complex supplier or construction contract for a Bangkok project. A lawyer can tailor risk allocation, delay penalties, and change order provisions to avoid later disputes.
• Negotiating a lease or sale of commercial property with a company or foreign party. An attorney can ensure clear rent terms, maintenance responsibilities, and exit clauses, plus registration steps for immovable property.
• Reviewing consumer or standard form contracts to spot unfair terms or hidden liabilities. A lawyer can request amendments to protect your rights under the Consumer Protection Act.
• Drafting or enforcing electronic contracts and data handling provisions. An attorney helps align contracts with the Electronic Transactions Act and data protection rules.
• Resolving contract disputes through litigation or arbitration including drafting or challenging arbitration clauses and governing law provisions.
• Cross-border transactions that involve Thai law and foreign terms. A lawyer ensures enforceability and compliance with local requirements.

3. Local Laws Overview

This section highlights two to three key Thai laws that govern สัญญา and related contract matters. Each law shapes how contracts are formed, performed, and enforced in Thailand.

Civil and Commercial Code (Book III and related provisions on obligations and contracts) governs contract formation, performance and remedies for breach. It remains the backbone of Thai contract law, with rules on consent, capacity, illegality, and damages for non-performance. It does not require consideration in the same sense as some common-law systems, but requires a valid and lawful objective and capacity to contract.

Electronic Transactions Act (ETA) B.E. 2544 (2001) and amendments recognizes electronic records and electronic signatures as legally effective when executed properly. This supports online contracts, electronic invoices, and digital agreements in commercial practice.

Consumer Protection Act B.E. 2522 (1979) and amendments addresses unfair contract terms and consumer rights in business dealings with individuals. It applies to many standard form contracts and products, and it provides remedies for deceptive acts or misrepresentations.

Recent trend note: Thailand is expanding enforcement of digital contracts and data handling practices under ETA and PDPA developments. Practical effects include clearer guidance on e-signatures, digital records, and data subject protections in contracts with Thai consumers and businesses.
