The following law applies when a person gives a loan to a colleague and afterwards, a third party says: "I will act as a guarantor," the lender sues the borrower and a third party says: "Let him go. I will act as a guarantor, or the lender was strangling the borrower in the market place and a third party says: "Let him go. I will act as a guarantor." The guarantor is not obligated at all. Even if the prospective guarantor says in the presence of a court: "I will guarantee the money," he is not liable. If, however, he formalizes his commitment to guarantee the money with a kinyan, he becomes obligated in all the above situations. This applies whether the kinyan was made in the presence of the court, or together with the lender alone.
