Cosigner(redirected from Cosigners)
Also found in: Dictionary, Thesaurus, Legal.
A person who signs a promissory note in such a capacity that he or she has equal and primary liability with another. Contrast with a guarantor, who is liable only if the original obligor defaults. A cosigner must list the promissory note as a liability on financial statements; a guarantor has only contingent liability which may never ripen into full liability.
