In finance, a surety , 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 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. The person or company providing the promise is also known as a "surety" or as a "guarantor". Overview A surety bond is defined as a contract among at least three parties: the obligee: the party who is the recipient of an obligation the principal: the primary party who will perform the contractual obligation the surety: who assures the obligee that the principal can perform the task European surety bonds can be issued by banks and surety companies. If issued by banks they are called "Bank Guaranties" in English and Cautions in French, if issued by a surety company they are called surety / bonds. They pay out cash to the limit of guaranty in the event of the default of the Principal to uphold his obligations to the Obligee, without reference by the Obligee to the Principal and against the Obligee's sole verified statement of claim to the bank. Through a surety bond, the surety agrees to uphold—for the benefit of the obligee—the contractual promises (obligations) made by the principal if the principal fails to uphold its promises to the obligee. The contract is formed so as to induce the obligee to contract with the principal, i.e., to demonstrate the credibility of the principal and guarantee performance and completion per the terms of the agreement. The principal will pay a premium (usually annually) in exchange for the bonding company's financial strength to extend surety credit. In the event of a claim, the surety will investigate it. If it turns out to be a valid claim, the surety will pay and then turn to the principal for reimbursement of the amount paid on the claim and any legal fees incurred. In some cases, the principal has a cause of action against another party for the principal's loss, and the surety will have a right of subrogation "step into the shoes of" the principal
