Tractate Bava Batra (the third of the three-part series of Nezikin, which covers interpersonal laws) deals with the rights and responsibilities that accompany property ownership.

The last chapter is devoted to the laws and conventions of documents. The conversation turns to the rights of a lien-holder regarding collecting payment from properties that have since been sold by the debtor, and to the responsibilities of the guarantor.

The tractate concludes by stating that a court mandated guarantor is obligated even if he did not formalize his obligation, because the very pleasure he receives from being accepted by the court as a reliable guarantor is considered an exchange for obligating himself to pay the possible debt.
