Illinois Bond-ADDitional-Surety (also known as an Illinois Surety Bond) is a type of surety bond required by the State of Illinois to guarantee the performance of a contract between two parties. The bond is a three-party agreement between the principal (the party performing the agreement), the obliged (the party receiving the performance) and the surety (the party guaranteeing the performance). The surety bond provides a financial guarantee that the principal will fulfill the contractual obligations of the agreement. In the event of a breach of contract, the obliged may make a claim against the bond for damages. The most common type of Illinois Bond-ADDitional-Surety is a Contractor Surety Bond, which is required by the Illinois Department of Financial and Professional Regulation for any contractor performing work in the state. Other types of Illinois Bond-ADDitional-Surety include License and Permit Surety Bonds, which are required by numerous state agencies, and Public Official Surety Bonds, which are required for public officials in certain positions.
