Legal Definitions - supplemental surety

A supplemental surety refers to an additional person or entity who provides an extra layer of guarantee for an obligation, typically when the initial guarantee is deemed insufficient or when the risk associated with the obligation increases. Essentially, they step in to provide further assurance that a primary party (the "principal") will fulfill their commitment, often financial, if the original guarantor's coverage is no longer enough.

Here are a few examples to illustrate this concept:

• Construction Project Expansion: Imagine a construction company (the principal) is building a new public library. To secure the contract, they obtain a performance bond from an insurance company (the original surety), which guarantees the project's completion even if the construction company defaults. Halfway through the project, the city council decides to add a significant new wing, substantially increasing the project's cost and complexity. The city (the obligee) now requires more financial assurance. To meet this new requirement, the construction company brings in a second insurance company (the supplemental surety) to provide an additional bond specifically covering the increased scope and risk of the expanded project. This second surety provides extra protection beyond what the original bond covered.

• Increased Bail Amount: A defendant (the principal) is arrested and a bail bond company (the original surety) posts a $50,000 bond to secure their release, guaranteeing the defendant will appear in court. Later, new evidence emerges, and the prosecutor successfully argues for the charges to be upgraded, leading the judge to increase the bail amount to $150,000. The original bail bond company may not be willing to cover the additional $100,000 without more security. To avoid remaining in jail, the defendant's family might convince a wealthy relative (the supplemental surety) to co-sign for the additional bond amount or provide collateral to the bail bond company, thereby providing the extra guarantee needed for the increased bail.

• Business Loan Restructuring: A small manufacturing business (the principal) has a line of credit with a bank, personally guaranteed by its founder (the original surety). Due to a sudden surge in demand, the business needs to significantly expand its production capacity, requiring a much larger loan. The bank (the obligee) reviews the new financial projections and determines that the founder's personal guarantee alone is no longer sufficient for the increased loan amount. To secure the necessary funding, the business's main investor (the supplemental surety) agrees to also guarantee a portion of the expanded loan, providing the bank with the additional security it requires to approve the larger credit facility.
