Thailand: Family, marriage and partnerships

Find out about family reunification and reporting requirements if you are planning to emigrate to Thailand. The FDFA can provide you with information about this.

Registering marriages and partnerships

Marriages contracted abroad under civil law are recognised in Switzerland and must be registered with the Swiss civil status authorities. Swiss nationals who get married abroad are required to register their marriage with the competent Swiss representation abroad. The documents must be submitted to the diplomatic representation together with an apostille. The latter will forward the declaration to Switzerland free of charge.

Find out what you need to do as early as possible

Before you get married, contact your Swiss representation to find out what you will need to do to make sure your marriage is recognised and registered in the civil status register without delay.

Registered partnerships

Same-sex marriage in Thailand became legal on 23 January 2025, with the Marriage Equality Act coming into force, making Thailand the first country in Southeast Asia to take this step. The law allows same-sex couples to register their marriage and grants them the same legal rights as heterosexual couples, including the right to adopt children, inherit property, and enjoy equal rights regarding consent to healthcare.
