The Wyoming Affidavit of Lost Check is a document used to certify the loss or theft of a check, and to provide information needed to process a reissue of the check. It is used to prove the identity of the owner of the check and the amount of the check. There are two types of Wyoming Affidavit of Lost Check: one for personal checks and one for business checks. The personal check affidavit requires the name and address of the mayor, the payee, the check number, and the amount of the check. The business check affidavit requires the name of the business, the address, the check number, the amount of the check, and the name of the person signing the affidavit. Both affidavits require the signer to swear or affirm to the truth of the information provided.
