In general, where two or more sureties are liable for the defaults of the same principal, the legal relationship between the sureties may be described as either "cosuretyship" or "subsuretyship". In cosuretyship, the sureties are equally liable for their aggregate share of the obligation. (The Law of Payment Bonds by Kevin L. Lybeck, H. Bruce Shreves, American Bar Association.
