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. The person or company providing the promise is also known as a "surety" or as a "guarantor".
A surety most typically requires a guarantor when the ability of the primary obligor, or principal, to perform its obligations to the obligee (counterparty) under a contract is in question or when there is some public or private interest that requires protection from the consequences of the principal's default or delinquency. In most common law jurisdictions, a contract of suretyship is subject to the Statute of Frauds (or its equivalent local laws) and is unenforceable unless it is recorded in writing and signed by the surety and by the principal.
In the United States, the Miller Act may require a surety bond for contractors on certain federal construction projects; in addition, many states have adopted their own "Little Miller Acts". The surety transaction will typically involve a producer; in the United States the National Association of Surety Bond Producers (NASBP) is a trade association that represents such producers.
If the surety is required to pay or perform due to the principal's failure to do so, the law will usually give the surety a right of subrogation, allowing the surety to "step into the shoes of" the principal and use the surety's contractual rights to recover the cost of making payment or performing on the principal's behalf, even in the absence of an express agreement to that effect between the surety and the principal.
Traditionally, a distinction was made between a suretyship arrangement and that of a guaranty. In both cases, the lender gained the ability to collect from another person in the event of a default by the principal. However, the surety's liability was joint and primary with the principal: the creditor could attempt to collect the debt from either party independently of the other. The guarantor's liability was ancillary and derivative: the creditor first had to attempt to collect the debt from the debtor before looking to the guarantor for payment. Many jurisdictions have abolished that distinction, in effect putting all guarantors in the position of the surety.
