Guarantor

Updated: 02 May 2026

What Does Guarantor Mean?

A guarantor is a third party in a contract who agrees to take responsibility for certain liabilities if one of the other parties defaults on their obligations. Guarantors are sometimes involved in insurance contracts, where they essentially provide a form of security or assurance, stepping in to cover obligations if necessary.

Insuranceopedia Explains Guarantor

Sometimes, one party can only secure a loan or get a project approved if a guarantor agrees to cover any potential losses or liabilities. This situation is especially common in the construction industry, where large sums of money are often invested in projects, and a guarantor provides additional assurance to mitigate financial risks. Many contractors also carry general contractor insurance on top of any guarantor arrangement, since a policy can cover payment obligations and project liabilities that a personal guarantee may not. Guarantors come up outside construction too, in commercial leases and supplier agreements where a company’s business insurance might cover some risks, but the other party still wants a backup if the business defaults.
