Meaning of AFFIDAVIT in English
A statement which before being signed, the person signing takes an oath that the contents are, to the best of their knowledge, true. It is also signed by a notary or some other judicial officer that can administer oaths, to the effect that the person signing the affidavit was under oath when doing so. These documents carry great weight in Courts to the extent that judges frequently accept an affidavit instead of the testimony of the witness .
