An instrument, in the legal context, refers to a document containing some legal right or obligation. Examples include contracts, bonds, and promissory notes. This form is a generic example of a security agreement in which a debtor has agreed that a secured party (e.g., a lender) may take specified collateral owned by the debtor if he or she should default on a loan or similar obligation. By creating a security interest, the secured party is also assured that if the debtor should go bankrupt, he or she may be able to recover the value of the debt by taking possession of the specified collateral instead of receiving only a portion of the borrowers property after it is divided among all creditors.
