Electronic Signatures
Sellers/servicers may use any form of electronic signature on an electronic record that is valid under applicable law except audio and video recordings, as long as the signature is attached to or logically associated with the record intended to be signed. From time to time, Fannie Mae may require a seller/servicer to use a specific signature format for a particular electronic record or type of record.
