Is a surety and guarantor the same thing?

A surety and a guarantor are similar but not identical concepts in finance and law. Both involve a third party agreeing to take on the obligation of a borrower if they default, but a surety is typically more directly involved in the transaction and may be liable as soon as the principal defaults. A guarantor, on the other hand, usually only becomes liable after the principal has failed to fulfill their obligations. Thus, while both provide security for a loan or obligation, their roles and responsibilities can differ.
