The Jewish Ethicist: Renege
from aish.com by Rabbi Dr. Asher Meir, Business Ethics Center of Jerusalem
Q. I agreed to use a certain service provider and even signed an agreement, but the agreement is not valid until I obtain some authorizations from the authorities, so I am technically able to withdraw. In the meantime I came across a better deal. Can I renege on the original agreement?
A. Jewish law, based on commandment and personal commitment, includes many obligations that are not enforceable. This is true even in business regulation. So even when an agreement is not enforceable, there may be an obligation to uphold it.
