Statement of Facts: The body of the affidavit contains the detailed information or facts that the affiant is attesting to. This section should be organized logically and clearly to present the information accurately.

Date and Signature: The affidavit includes the date it was signed by the affiant. The affiant must sign the document in front of an authorized individual, such as a notary public or court clerk.
