Notarisation and Apostille for Immigration: When Do You Need Them?

Written by Global Immigrate consultants · Reviewed by Oscar Yip, Founder & Managing Director

Summary

Birth, marriage and police documents often need notarisation; some countries require an apostille or consular legalisation. Common scenarios and the right order to avoid rejection.

Short answer: notarisation confirms a signature or true copy; an apostille is used between Hague Convention countries for public documents. Non-members may need consular legalisation. Confirm the receiving country’s rule before you start.

Documents often needing formalities

  • Birth, marriage, divorce certificates
  • Police certificates
  • Education and company documents (programme-dependent)

Suggested order

  1. Confirm notarisation, apostille or dual legalisation
  2. Issue → notarise → legalise per local process
  3. Confirm whether translations must be legalised too

Wrong formalities can send the whole package back.
