A national of South Korea marrying in Thailand — what does the age and gender rules require?

The point raised here is “A national of South Korea marrying in Thailand”, so the answer below starts with what this case actually needs before setting out the general rules. Before starting, verify the source document is still within any validity window the recipient applies, then count the number of certified sets needed before work starts, because extra sets restart the certification steps, then confirm with the receiving body whether it wants an original, a certified copy or a certified translation. The point to fix before starting is the real deadline, so the steps can be scheduled backwards from it. A key variable is the filing channel (in person, agent or online), which sets the copy format to prepare. The terms that frame this page are national · South · Korea · marrying. The specifics here are destination: Kr, and those decide which translation and certification level applies. After filing, follow up on the cycle the office states rather than waiting past the deadline. Keep a copy of every source document plus the receipt or docket from each step. High-resolution photos of seals and signatures help when the destination asks for re-verification. With a fixed filing date, count backwards from it and book each certification step in reverse. Public holidays and embassy closures move certification queues more than most people expect. Since the Act Amending the Civil and Commercial Code (No. 24) B.E. 2567 came into force on 22 January 2025, marriage is open to two persons of any gender and the minimum age is 18 completed years under section 1448; below that a court order is required. The registrar always checks the statutory bars: an existing marriage (s.1452), close blood relationship or full/half siblings (s.1450), adoptive parent and adopted child (s.1451), and a person of unsound mind or adjudged incompetent (s.1449). The foreign party normally needs an affidavit or certificate of freedom to marry issued or notarised by their embassy or consulate in Thailand, then translated into Thai and legalised by the Legalization Division, Department of Consular Affairs, Ministry of Foreign Affairs (Chaeng Wattana) before it is filed with the registrar; each embassy sets its own issuing conditions, not ILC. Fees and scheduling depend on nationality, how many documents need translation and legalisation, the embassy involved and the district office used; we confirm scope in writing before starting.
