What is Legalisation?
The layered process by which government offices and an embassy confirm signatures and seals on a document.
In detail
Legalisation authenticates the chain of signatures and seals rather than the content of the document. It usually starts with the issuing authority or a notarial attorney, continues at the Legalisation Division of the Department of Consular Affairs, Ministry of Foreign Affairs, and ends at the destination country's embassy. Each office only confirms that the previous signature is genuine.
คำอธิบายภาษาไทย — การรับรองนิติกรณ์เอกสาร (Legalization)
การรับรองนิติกรณ์เป็นการยืนยันเป็นชั้น ๆ ว่าลายมือชื่อและตราประทับบนเอกสารเป็นของเจ้าหน้าที่ผู้มีอำนาจจริง โดยทั่วไปเริ่มจากผู้รับรองต้นทาง (เช่น ทนายผู้ทำคำรับรองหรือหน่วยงานผู้ออกเอกสาร) ต่อด้วยกองสัญชาติและนิติกรณ์ กรมการกงสุล กระทรวงการต่างประเทศ และปิดท้ายที่สถานเอกอัครราชทูตของประเทศปลายทาง สิ่งที่รับรองคือความถูกต้องของลายมือชื่อ ไม่ใช่ความถูกต้องของเนื้อหาในเอกสาร
