A Nevada Social Security Affidavit is a document used to verify a person's Social Security number for various legal purposes. It is commonly used in court proceedings, real estate transactions, and other legal documents. The affidavit must be signed by both the affine (the person swearing to the truth of the statement) and the notary public or other qualified witness. There are two types of Nevada Social Security Affidavits: the Nevada Affidavit of Social Security Number and the Nevada Declaration of Social Security Number. The Nevada Affidavit of Social Security Number is used to certify a person's Social Security number, and it requires a notarized signature. The Nevada Declaration of Social Security Number is a sworn statement that indicates a person's Social Security number but does not require a notarized signature.
