Navigating the family law system in Thailand can be challenging.Eespecially for foreigners who may not be familiar with the laws and procedures. This article aims to provide a basic understanding of family law in Thailand. We focus on marriage registration, parental rights, divorce and adoption. Book V of the Commercial and Civil Code in Thailand (Hereafter CCCT), sections1435-1598 is where you find most of the following. The conflict of law act and some others laws could also be included into family law in Thailand.
1. Marriage Registration Thailand
In Thailand, a legal marriage must be registered with the government to be recognized. A legal marriage in Thailand can be between a Thai and non-Thai national, or between two non-Thai nationals. The process for registering a marriage in Thailand is relatively straightforward but can be time-consuming and complex, particularly for foreigners.
The following is a step-by-step guide on how to go about the process of marriage registration in Thailand:
- If one of the parties is a foreigner, they must verify with their embassy to get a document called “afffirmation to get married in Thailand”. Once you have this document, it must be translated in Thai and legalized by the ministry of foreign affairs. Do note that each embassy can have its own rules. Some will need a previous appointment, some will need specific documents, others might interview your fiancé(e). Contact your embasy.
- If you want a prenuptial agreement, that must be written before you get married and registered at the marriage. Prenuptial agreements are valid in Thailand subjects to the requirements of the law.
- Visit the local district office or the Amphur office (also known as the registration office) where one of the couple resides in person.
- Provide proof of identity, such as a passport, and proof of current marital status, such as a divorce certificate or a death certificate of the former spouse (if applicable). Foreigners will need the affirmation to get married from their embassy, translated in Thai and legalized.
- Provide two witnesses who are at least 15 years old and have a Thai ID card.
- Provide a translator if either party or both are not fluent in Thai.
- Complete and sign the marriage registration form, which will then be read to both parties in Thai and English.
- Pay the marriage registration fee.
Marriage certificate and conditions of marriage
You will normally get the marriage certificate the same day and the process is quick. The marriage certificate is a legal document that proves that a couple is legally married in Thailand. It could be used for obtaining a visa and other legal purposes. We will not talk in this article about Khongman (property given to the fiancée) or Sinsod (property given to the parents of the fiancée). If the marriage does not take place, the male party could claim back the sinsod paid to the family.

It is important to note that in Thailand, the legal age of marriage is at least 17 years old. If a party is under 20 years old, they will need to provide written consent from their parents or legal guardians.
2. Same-sex civil partnership or same-sex marriage
There is currently no laws or disposition allowing same-sex marriage. However, the government has been talking about it for few years.
3. Parental Rights in Thailand
Parental rights in Thailand are governed by the CCCT which covers the rights and obligations of parents towards their children. They include legal custody, physical custody, visitation rights, and child support.
Legal custody refers to the right to make decisions about a child’s upbringing, such as education, healthcare, and religion. Physical custody refers to the right to have the child live with one or both parents. Visitation rights refer to the right to visit or have contact with the child, even if the child does not live with the parent. Child support refers to the financial support that parents must provide for their child’s upbringing.
a) If the parents are not married
In Thailand, only the mother will have parental rights under section 15446 of the TCCC unless the father does one of the 3 steps written at the following clause, 1547. We strongly suggest to a father that is not married to the mother to legitimate his rights as father by asking the court to do it. The court will normally accept unless the other party can prove that it is NOT in the best interest of the child.
b) If the parents are married
If the couple is married, in Thailand, parental rights are usually given to both parents equally. If there is a reason to believe that giving sole custody is in the best interest of the child the Court can allow it. This means that normally both parents have equal rights. Both can make decisions about their child’s upbringing, and both parents have the right to have the child live with them.
If a couple is divorced or separated, parental rights and responsibilities must be established, either by agreement or through the court system. If a couple is unable to reach an agreement, a court may decide on the custody, visitation, and child support arrangement based on the best interests of the child. Unless the proof is really strong against a party, the family Court tends to give joint parental powers to the father and mother.
4. Divorce in Thailand
A divorce lawyer in Thailand can help you navigate the complex legal system and ensure that your rights and interests are protected. They can advise you on everything from the grounds for divorce to child custody and alimony, and can help you negotiate a fair settlement with your ex-spouse.
In order to find the right divorce lawyer, it is important to do your research and choose someone with experience and a track record of success. Look for a lawyer who has expertise in Thai family law and who has worked with expats in the past. You should also ask for references and read online reviews before making your final decision.
There are 2 ways to divorce under Thai law:
a) A divorce by mutual consent at the amphur.
Obviously the easiest and fastest way. Your marriage must have been registered in Thailand.Iif not, you might first register your marriage at the amphur or go to the Court.

Burden of proof
The party who wishes to divorce has the burden of proof by balance of probabilities.
c) How will a court act in a divorce case
i)First, they were be a negotiation session in Court. A party can refuse to negotiate but the court do like when parties agree and settle.
ii) If they can’t agree, the Court will verify if the plaintiff has a ground under the law.
iii) if the couple has a a child, the Court will make a decision in the best interest of the child which is normally joint custody.
iv) Lastly, the court will examine the assets of the couple. Each party will keep his personal property (called Sin Suan Tua in Thai). The marital property (Called Sin Somros in that) should be divided equally between the parties.
Rarely, the Court will allow alimony to a party but they will ask support for the child. Example, if the court finds that the best interest of the child is to stay with the mother most of the time, the father will have to pay some support. The amounts are not fixed by law, the court will try the parties to agree and if not, the Court will decide.
d) Adultery
If a party commits adultery, the victim party can claim damages from their spouse and the person who committed adultery with the spouse.
e) Alimony
In Thailand, alimony is determined by a number of factors, including the length of the marriage, the income and assets of both parties, and their financial needs. The court will also take into account any child support payments that are being made. In reality, alimony is rarely awarded. In most cases, the court will simply divide the common property between the two parties equally.
5. Annulment of a marriage
A marriage can be annulled if there was a mistake about the identity of a party, fraud, duress, or if the marriage was not performed according to the law (for example, if one of the parties was not of legal age). Only the innocent party can apply for an annulment.
6. Adoption in Thailand
The process of adoption is different for Thai people and foreigners. Foreigners must go through the DSDW (Department of Social Development and Welfare) in order to be granted an adoption in Thailand. Adults can also be adopted, but they must meet certain requirements.
