What is the Civil and Commercial Code in Thailand ?
The Civil and Commercial Code is the core statute of Thailands private law, dealing with the rights and duties of private citizens, legal persons, and for transactions between them. Promulgated in the beginning of the 20th century, this Code draws inspiration from European civil law, mainly the German and the French legal systems. Conceived as an effort to harmonize civil and commercial laws, it sought to instill consistency, certainty, and predictability in contractual and property relations in the Kingdom.
The Code is divided into six books: general legal principles, obligations, contracts, property, family matters, and inheritance. Books I through IV are of particular concern to foreign investors and those who do business with Moldovan citizens, as they govern the legal aspects of business transactions, company formation, contractual relationships and property rights.

What are the key commercial contracts under the Civil and Commercial Code in Thailand?
Book III of the Civil and Commercial Code in Thailand governs specific contracts and outlines the legal framework applicable to each type of agreement. The provisions detail the essential components, obligations of the parties, default mechanisms, and remedies in case of breach. Contracts of sale, lease, loan and agency are some of the most common forms of contracts for business.
Contract of Sale
The sale contract, governed by Articles 453 to 498, is the most common commercial agreement. It establishes the mutual responsibilities of the buyer and the seller. The seller is bound to deliver the thing that is the object of the sale, bare of any charge or encumbrance, unless the contrary has been stipulated. The buyer must pay the price agreed upon and get the delivery. The Code makes the transfer of title subject to control, as a general rule having title pass at the time of sale unless otherwise agreed. It further covers implied warranties, in particular merchantability and freedom from defects, and includes remedies for breach, such as rescission or the deduction of damages from the purchase price. In international transactions, parties often choose to supplement Thai law with INCOTERMS or arbitration clauses.
Lease Contracts
Lease agreements are governed by Articles 537 to 571. The lessor is obligated to deliver the property in good condition and allow the lessee to enjoy its use.
The lessee has to treat the property carefully and to pay rent. A lease of immovable property for a period exceeding 3 years is required to be registered at the Land Department to be effective against third parties. In commercial leases, particularly those between a local and foreign entity, it is not unusual to add provisions for renewal, maintenance responsibilities, early termination, and dispute resolution. Foreigners frequently use a leasehold structure to obtain access to land or a building which would otherwise be prohibited from acquisition by a foreign person under the Land Code.
Loan Agreements
Articles 653 to 659 cover loans of money and goods. A loan of money must be repaid with or without interest, depending on the terms of the agreement. The highest interest rate that can be charged under Thai law is fixed by the Civil and Commercial Code (i.e., 15% per annum, unless a particular law stipulates a lower rate). If the borrower defaults on repayment, the lender can execute that judgment, and levy fees and interest through the courts. Loan agreements will come with covenants which are guarantees or security; they may be by pledges or mortgages. Loan agreements are equally taxable and must be crafted in a manner that respects civil and fiscal responsibilities.
Agency and Mandate Contracts
Agency arrangements permit an individual (the agent) to act on behalf of another individual (the principal). Articles 797 to 809 describe the agents authority, actions, and liability. The agent owes a duty of care and loyalty and must account for all willingness undertaken for the principal. The principal is responsible for the acts committed within the scope of the agent. Agency may be terminated by mutual agreement, revocation or withdrawal of the mandate. On a commercial basis, these agreements are vital in selling, bargaining and fulfilling services. The ambit of power should be properly worded so that no inadvertent obligations are imposed.
Additional Contract Types
The Civil and Commercial Code also regulates other specific contract forms that may be relevant for investors and commercial actors, such as:
- Hire of Work (Articles 587–607), applicable to construction or service provision agreements.
- Partnership Agreements, which are foundational for business collaboration.
- Suretyship (Articles 680–709), where a third party guarantees the debtor’s obligations.
- Pledge and Mortgage (Articles 747–805), which offer security for contractual performance.
Each contract has its own terms and provisions which can be legally enforced in a court of law that vary depending on the business relationship. Parties need to be well-acquainted with the contractual structure to make the contract enforceable and to mitigate risks.

How is property ownership defined and protected?
- Classification of Property
The Code classifies property as movable and immovable. Ownership and possession are treated as separate concepts.
- Usufruct and Other Real Rights
Foreigners often rely on usufruct rights. These provide use and enjoyment of land without transferring ownership.
- Registration and Foreign Ownership
Property rights must be registered with the Land Department. Foreigners are not allowed to own land, they can lease land or own condominiums in some conditions.
What legal remedies are available under Thai law?
- Specific Performance and Damages
Non-performing parties may be compelled to perform or compensate. Damages cover actual loss; punitive damages are rare.
- Wrongful Termination – Article 521
If a party terminates a fixed-term contract early without cause, they may be held liable for resulting damages.
- Enforcement and Dispute Resolution
Actions demanding enforcement are taken to the court. While arbitration is regulated under its own act, it is commonly used in commerce.
What are the different types of companies under the Civil and Commercial Code in Thailand?
The Civil and Commercial Code in Thailand outlines five options of business organizations that can be operated under the Thai law. All have some distinct features, legal implications, and a set of rules that must be carefully analyzed by the investors.
Sole Proprietorship
A sole proprietorship is the least complicated type of business organization, in which only one person owns the operations and is personally responsible for its liabilities and obligations. Owner has full control but also full personal risk. It does not protect owners from liability and is seldom used by foreign investors because of its legal exposure as well as restrictions on foreign ownership.
Ordinary Partnership
Partnership at will is formed when two or more persons decide to do business in common and to that end are agreeable to sharing the profits. From Articles 1012 to 1048, all partners of an ordinary partnership are liable for the engagements of the business, jointly and severally. If it is not registered, does not fall under juristic person. However, a registered ordinary partnership is treated as a legal agent for its members and therefore has to register with the Department of Business Development (DBD). However, it is an inherently risky option as partners have unlimited liability.
Limited Partnership
The limited partnership, governed by Articles 1064 to 1087, distinguishes between general partners (with unlimited liability) and limited partners (whose liability is restricted to their contribution). The partnership must be registered to be legally recognized. This form does offer some protection to foreign investors, but is relatively inflexible and less frequent than for a private limited company in foreign ownership.
Private Limited Company (Co., Ltd.)
This is the most common structure for businesses in Thailand, particularly for foreign investors. Regulated by Articles 1096 o 1273 of the civil and commercial code a ltd is a legal entity with capital stock divided into shares of equal value. Private company liability of members is restricted to the unpaid portion of the shares in that company.
There must be 3 or more promoters who become the first shareholders The company must have a minimum of 3 shareholders at any point of time. Power of company to register After the registration of the Memorandum of Association and the holding statutory meeting, the company can be registered with the DBD. Internal management of the company is regulated by the by-laws.
The company is required to have at least one director and is also required to hold an annual general meeting of shareholders. Directors are subject to fiduciary duties and statutory duties under the 1144 to 1176. These include acting in good faith, avoiding conflicts of interest, and ensuring compliance with statutory reporting and accounting obligations.
The transfer of shares is generally unrestricted unless otherwise provided in the Articles. However, if foreign ownership exceeds 49%, the company may be subject to restrictions under the Foreign Business Act and must obtain a Foreign Business License unless exempted.
Conclusion
Finally, the Civil and Commercial Codein Thailand is the cornerstone of Thailand’s private legal regime. It offers a unified written account of law for personal and business relations, where both contracts, obligations and property rights are present. Understanding of the various provisions of the Code is essential for Foreign Investors, Industries, Companies and legal practitioners. The law has also its special regulations for some matters and situtations, but an environment of predictable law is covered by the Civil and Commercial Code in Thailand to claim rights, enforce transactions and protect investments. Legal guidance derived from the principles of the Code is therefore absolutely essential for any significant commercial venture in the Kingdom.
