The law of contracts is an important part of any legal system. A major challenge in this regard is how sanctions are determined in the event of the breach of a contract. Consistent with a set of pre-determined goals, all legal systems have made certain rules for the breach of contractual obligations. In the law of the United States, a strict liability system governs in terms of preservation of a contract as well as compensations for the damages of a contract breach. Nevertheless, drawing on the different aspects of the consequences of this liability, researchers have developed new perspectives on the fault-based enforcement of liability in recent decades. The Iranian Law, rooted in the Islamic jurisprudence (the Fiqh), limits the claim for contractual damages circumstantially to the affirmation of parties, customary law, or civil laws due to the differing opinions of Islamic jurists (the Foqahā) on the issue. Following the aims of the laws of civil liability in fully compensating for the damages incurred to contract parties, the loss can be estimated according to its attributability to the offending obligator. Use was made of the descriptive, analytical, and comparative methods in carrying out the present study.
