Suretyship is the law of contract, agreements of all kinds between people. The tractate looks at the duties and role of the surety, the third person in any agreement: the buyer, or debtor; the seller, and the surety, who was to ensure that the agreement was completed in accordance to that which was agreed upon in his presence.
