An affidavit for a court case is a sworn statement of facts, made under oath and in writing. It is the official way for parties to the litigation to provide evidence to the court without having to undergo cross-examination. The affiant must sign the document in front of an eligible witness, such as a notary public or other recognized judicial officer, who will certify that the affiant’s signature is authentic. Affidavits are typically used in conjunction with other evidence presented to the court. They can be a very effective way to present your side of the story in a court case.
