Introduction

Adultery is a highly contentious issue in many legal systems, and Thailand is no exception. While Thailand does not criminalize adultery, its legal framework provides for civil remedies under the Thai Civil and Commercial Code, particularly Section 1523, which allows the innocent spouse to claim damages. Foreigners residing in or visiting Thailand should be particularly aware of these laws to avoid legal repercussions.

This article examines Adultery Laws in Thailand, exploring the different interpretations of liability, legal precedents, and practical considerations. We also provide insights into how a Lead law firm in Bangkok can assist individuals facing adultery-related lawsuits.


1. Legal Framework Governing Adultery in Thailand

1.1 Civil Liability Under Section 1523

Section 1523 of the Thai Civil and Commercial Code provides that a spouse can seek compensation from a third party involved in an extramarital affair. Unlike criminal law, where intent is usually a requirement, civil liability under Section 1523 has been subject to differing judicial interpretations.

1.2 Two Interpretations of Liability

Legal scholars and court precedents have given rise to two main perspectives on the liability of a third party in an adulterous relationship:

1.2.1 Intent-Based Liability

  • This interpretation suggests that the third party must have knowingly engaged in an adulterous relationship.

  • If the third party was unaware of their partner’s marital status, they should not be held liable for damages.

  • This aligns with general tort principles, where intent or negligence is typically required to establish liability.

  • Supporters include Professor Prasobsuk Boondej, a Thai legal scholar who argues that strict liability could result in unjust penalties for individuals who unknowingly become involved in extramarital affairs.

1.2.2 Strict Liability

  • The strict liability approach holds that a third party involved in an adulterous relationship is liable for damages, regardless of whether they knew their partner was married.

  • The justification for this approach is to protect the sanctity of marriage and prevent harm to the innocent spouse.

  • While liability is absolute, Thai courts have discretion to adjust the compensation amount based on the facts of the case.

  • Legal scholars such as Professor Chatchai Akaraviboon support this interpretation.

  • Thai Supreme Court Decision No. 1113/1958 upheld this principle, ruling that the intent of the third party is irrelevant in determining liability.

1.3 Legal Precedents on Adultery-Related Damages

Several Thai court decisions have reinforced the principle of liability for adultery, particularly in cases where the affair was well-documented. Courts typically assess:

  • The duration of the affair

  • The extent of emotional and financial damage to the innocent spouse

  • Whether the marital relationship was already broken before the affair began


2. Compensation and Legal Remedies for Adultery

2.1 Determining the Compensation Amount

While Thai law allows for financial compensation, the courts have discretion to assess damages based on:

  • The emotional suffering of the innocent spouse

  • The financial burden caused by the affair

  • Whether the third party was aware of the marriage

Recent Thai court rulings suggest that compensation amounts vary significantly, with some awards reaching millions of baht in cases involving high-profile individuals.

2.2 Possible Defenses Against Adultery Lawsuits

Individuals sued under Adultery Laws in Thailand may present the following defenses:

  1. Lack of Knowledge – Arguing that they were unaware of their partner’s marital status.

  2. Consent of the Spouse – If the innocent spouse consented to the affair, liability may not be established.

  3. Pre-Existing Marital Breakdown – If the marriage was irreparably broken before the affair, courts may reduce or dismiss damages.

  4. Lack of Sufficient Evidence – The burden of proof lies with the plaintiff.

A Lead law firm in Bangkok can provide strategic legal defenses in adultery cases to mitigate or eliminate liability.


3. Practical Considerations for Foreigners in Thailand

Foreigners, including expatriates and tourists, should be aware of the following:

  • Thailand’s emphasis on family stability – Even unintentional involvement in an extramarital affair can lead to lawsuits.

  • Verification of a partner’s marital status – Conducting background checks or seeking legal advice can prevent legal disputes.

  • Legal representation – If accused of adultery, securing the services of a Lead law firm in Bangkok is essential.

A Lead law firm in Bangkok specializing in family law can help in various ways:

  • Pre-Litigation Advice – Evaluating risks before entering a relationship.

  • Legal Defense – Challenging lawsuits on legal grounds.

  • Negotiation and Settlement – Reducing potential damages through mediation.
