Surety

In finance, a surety /ˈʃʊərɪti/, surety bond, or guaranty involves a promise by one party to assume responsibility for the debt obligation of a borrower if that borrower defaults. Usually, a surety bond or surety is a promise by a person or company (a surety or guarantor) to pay one party (the obligee) a certain amount if a second party (the principal) fails to meet some obligation, such as fulfilling the terms of a contract. The surety bond protects the obligee against losses resulting from the principal's failure to meet the obligation.
