Anyone ever heard of a promissory note?
Heard of it.. zero security..
Any note in which the borrower promises to pay back (essentially any written note) is a promissory note. When the promissory note is backed by real property an additional document, either a deed of trust or a mortgage instrument is needed to perfect the security interest in the collateral. If personal property is used as security for the promissory note then a UCC filing is used describing the collateral and placing public notice in the state/county business filings that the particular personal property is impaired. A promissory note unaccompanied by an instrument securing collateral is an unsecured promissory note.
