The signature date is the date a signer signed a document. The signature date on the Right to Cancel is especially critical as the borrower has three days to cancel the loan after they sign that document. Sometimes two signers will sign the same document on a different date, and perhaps different county or state as well. Husbands and wives are not always at the same place at the same time. Signature dates can be before the notarization of an acknolwedged signature. However, signature dates for Jurats must be when the notarization took place and must be signed before the notary and signatures must be accompanied by a verbal oath in the case of a Jurat.
