What is Affidavit?

A written statement of facts sworn or affirmed before an authorised officer.

In detail

Affidavits are widely used in litigation and foreign administrative filings — confirming single status, family relationships, or source of funds. The deponent must sign in the presence of the officer, who records the date, time and place and verifies identity. A false statement can expose the deponent to penalties in the jurisdiction where the affidavit is used.
