Thailand follows the Civil Law system, which is primarily based on written legislation rather than case law. The framework of Thai law has been shaped by a combination of influences:

• Traditional Thai customs that continue to play a role in family and property matters.
• European civil codes, especially German, French, and Swiss law, which inspired the drafting of Thailand’s Civil and Commercial Code in the early 20th century.
• Modern regulations and statutes passed by Parliament to address evolving economic, social, and international needs.

The Constitution of Thailand stands as the supreme law of the land. All statutes and regulations must comply with it. Beneath the Constitution, a hierarchy of laws governs everyday life, business transactions, and dispute resolution.

For foreigners, understanding this foundation is key to:

• Ensuring contracts are enforceable under Thai law.
• Protecting investments in real estate, business, or joint ventures.
• Preparing for potential disputes and knowing which courts or procedures apply.

Although Thailand is a civil law country, in practice litigation cannot avoid referencing past Supreme Court judgments. Lawyers and judges often compare similar rulings to strengthen arguments, identify winning strategies, and guide the court in interpreting the law in each case. Judicial precedents therefore play a persuasive though not binding role in shaping outcomes.

Thai law balances local traditions with international influences, creating a unique legal environment where professional guidance is essential.

For foreigners living, working, or conducting transactions in Thailand, understanding the local legal framework is essential. Thai law governs everyday interactions whether personal, contractual, or in the event of disputes.

Key reasons include:

• Contracts and Agreements
  Written contracts must comply with Thai legal standards to be valid and enforceable. Even if a contract is drafted under foreign law, disputes arising in Thailand are likely to be resolved under Thai jurisdiction.
• Legal Rights and Responsibilities
  Foreigners are subject to Thai civil and criminal law in the same way as Thai nationals. Being aware of obligations and protections helps avoid misunderstandings or unintentional violations.
• Dispute Resolution
  If a conflict arises whether personal or commercial resolution will follow Thai legal procedures. This means preparing evidence, understanding court rules, and navigating appeals within the Thai judiciary system.

In short, awareness of Thai law gives foreigners clarity, protection, and preparedness when entering into legal relationships or facing disputes in Thailand.

Thai law is built on a structured hierarchy of legal sources. Understanding where laws come from helps foreigners see how rules are applied in daily life and in court proceedings.

1. The Constitution

• The highest law in Thailand.
• All statutes, regulations, and government actions must comply with it.
• Provides fundamental rights and the framework of government.

2. Acts and Codes

• Passed by Parliament and form the main body of law.
• Key examples include the Civil and Commercial Code, Criminal Code, and Civil Procedure Code.
• These cover contracts, family, inheritance, business, criminal offenses, and legal procedures.

3. Royal Decrees, Ministerial Regulations, and Notifications

• Issued by the executive branch to implement and enforce Acts.
• Often provide detailed rules for practical application.

4. Subordinate Legislation & Local Regulations

• Rules made by local administrative bodies or government agencies.
• Applicable to specific industries, localities, or administrative matters.

5. Judicial Precedents

• Thailand is a civil law system, so court judgments are not strictly binding like in common law.
• However, Supreme Court decisions carry persuasive authority.
• In practice, judges and lawyers frequently rely on past judgments to interpret provisions, compare cases, and strengthen arguments.

Therefore, while statutes are the backbone of Thai law, judicial interpretation plays an important role in shaping how the law is applied in real disputes.

Thailand has a multi-tiered court system designed to handle different types of disputes. Understanding which court has jurisdiction is essential, as it determines how a case will proceed and which procedures apply.

1. Courts of First Instance

• These are the trial courts where cases begin.
• Divided into Provincial Courts (for civil, criminal, and general cases outside Bangkok) and Municipal Courts (smaller claims within municipalities).

2. Court of Appeal

• Reviews cases from the trial courts if a party files an appeal.
• Focuses on points of law and fact raised in the lower court judgment.

3. Supreme Court (Dika Court)

• The highest court in Thailand.
• Decisions are final and cannot be appealed further.
• Plays a critical role in setting persuasive legal interpretations.

4. Specialized Courts

Certain disputes require expertise and are directed to specialized courts:

• Labour Court – disputes between employers and employees.
• Tax Court – disputes involving taxation.
• Intellectual Property and International Trade Court – IP, customs, and international trade disputes.
• Administrative Court – cases against government agencies or officials.
• Juvenile and Family Court – family and child-related matters.

5. Jurisdiction Considerations

Jurisdiction is generally determined by:

• Subject matter – whether it concerns civil, criminal, labor, tax, or administrative law.
• Value of the claim – higher value claims may be assigned to higher courts.
• Geographic location – cases are filed in the court covering the area where:
  • the dispute arose, or
  • the defendant has his/her domicile

For foreigners, knowing which court will hear a case is important for preparing evidence, anticipating timelines, and understanding possible appeals.

Court proceedings in Thailand follow a structured civil law process. Whether in civil or criminal matters, the steps are clearly defined by the law.

1. Filing a Complaint

• The plaintiff submits a written complaint to the competent court.
• The court reviews the complaint to ensure it meets legal requirements.

2. Court Acceptance & Summons

• Once accepted, the court issues a summons for the defendant.
• The defendant must appear and file a defense (written answer) within the prescribed period.

3. Preliminary Hearing / Mediation

• Before trial, the court often encourages mediation.
• If the parties can settle, the case may conclude without a full trial.
• If not, the case moves forward to trial.

4. Trial (Examination of Evidence)

• Both sides present evidence and witnesses before the judge.
• Unlike common law countries, there is no jury system in Thailand.
• Judges take an active role in questioning and reviewing evidence.

5. Judgment

• After hearings conclude, the court issues a written judgment.
• The decision is based on both statutory law and, where relevant, past Supreme Court precedents for guidance.

6. Appeal

• Parties may appeal to the Court of Appeal, and ultimately to the Supreme Court, depending on the case.
• Appeals focus on points of law, and sometimes facts, within the limits allowed by procedure.

7. Execution of Judgment

• If the losing party fails to comply voluntarily, the winning party may request execution.
• The court will authorize measures such as asset seizure, auctions, or garnishment to satisfy the judgment.

For foreigners, it is important to note that Thai proceedings are document-intensive and highly procedural. Having local legal representation ensures filings, evidence, and arguments comply with court rules to avoid delays or dismissal.

In Thailand, parties have several options for resolving disputes. Choosing the right path depends on the nature of the conflict, the relationship between the parties, and the desired outcome.

1. Court Litigation

• The most common method of dispute resolution.
• Conducted before the Thai courts under the Civil Procedure Code or Criminal Procedure Code.
• Suitable when a binding and enforceable judgment is required.
• Can be time-consuming, but judgments can be executed through court-authorized measures.

2. Arbitration

• An alternative to court proceedings, especially in commercial disputes.
• Parties agree to submit disputes to an arbitral tribunal rather than the court.
• Thailand has its own Arbitration Act, and awards can be enforced by Thai courts.
• Often chosen for international contracts as it offers flexibility, confidentiality, and specialized expertise.

3. Mediation

• Increasingly encouraged by Thai courts before trial.
• A neutral mediator helps parties negotiate a settlement.
• Saves time and costs if successful.
• Agreements reached in court-annexed mediation can be made legally binding.

While litigation remains the traditional path, arbitration and mediation are effective alternatives often faster and less adversarial. For foreigners, understanding these options allows better planning and helps choose the most efficient way to resolve disputes.

Navigating the Thai legal system can be challenging for foreigners due to language barriers, cultural differences, and procedural complexities. This is where legal advisors play a critical role.
