Thailand Marriage Laws
Understanding Thailand Marriage Laws
Thailand marriage laws establish the legal requirements and procedures for couples who wish to marry in the Kingdom of Thailand. These laws apply to Thai citizens, foreign nationals, international couples, and same-sex couples seeking legal recognition of their marriage under Thai law.
Following the implementation of Thailand’s Marriage Equality Act on January 22, 2025, marriage rights are now available to all couples regardless of gender, providing equal legal protection and recognition throughout Thailand.
Whether you are planning to marry a Thai citizen, another foreign national, or your same-sex partner, understanding Thailand marriage laws is essential before beginning the marriage registration process.
Who Can Legally Marry in Thailand?
Under Thailand marriage laws, the following couples may legally register their marriage:
- Two Thai citizens
- A Thai citizen and a foreign national
- Two foreign nationals
- Opposite-sex couples
- Same-sex couples
Marriage registered in Thailand is legally recognized by the Thai government and carries the same legal rights and obligations for all eligible couples.
Legal Requirements for Marriage in Thailand
To marry legally in Thailand, both parties must satisfy the following requirements:
Minimum Age Requirement
Both individuals must generally be at least 17 years old. In certain situations, a Thai court may grant permission for marriage at a younger age.
Legal Capacity
Both parties must be mentally competent and legally capable of entering into a marriage contract.
Single Status Requirement
Neither individual may be legally married to another person at the time of registration. Any previous marriage must have been legally terminated through divorce, annulment, or the death of a spouse.
Family Relationship Restrictions
Thailand marriage laws prohibit marriage between close blood relatives and certain adoptive family relationships.
Waiting Period After Divorce
A woman whose previous marriage has ended through divorce or widowhood is generally required to wait 310 days before registering a new marriage, unless an exception under Thai law applies.
Same-Sex Marriage Laws in Thailand
Thailand became the first country in Southeast Asia to legalize same-sex marriage. Since January 22, 2025, same-sex couples have been entitled to the same legal rights, protections, responsibilities, and benefits as all married couples under Thai law.
This includes rights relating to:
- Marriage registration
- Property ownership
- Inheritance
- Medical decision-making

Assets acquired during the marriage may be considered jointly owned marital property, while certain personal assets acquired before marriage may remain separate property.
Couples may choose to establish a prenuptial agreement before marriage registration to clarify ownership and financial arrangements.
A valid prenuptial agreement must be completed and registered at the same time as the marriage registration.
