Thailand is tightening checks on children leaving the country following an investigation into paternity fraud cases. Starting October 29, 2026, Thai travelers under the age of 18 must be prepared to present a birth certificate when departing Thailand. Immigration officers may accept the original, a copy, or an electronic image. If a parental consent document is required, it must be issued or certified by a government agency. The Royal Thai Police announced on October 27, 2026, that they had identified 1,483 suspicious cases and confirmed 24 children whose registered Thai father was not their biological father. 2026-10-29
