Obligation to Fulfill an Early Commitment in a Hypothetical Violation in the Legal System of Common Law and Imamiyyah Jurisprudence

The obligation to perform a pre-contractual obligation is the place of dispute in legal systems and has not been stipulated in Imamiyyah jurisprudence. By virtue of this right, an obligee who before the due date of a commitment has reached the conclusion reasonably and normally that the obligor will not fulfill his/her contractual obligation at the due time for any reason has the discretion to oblige him to fulfill his/her obligation before the due date. This research, using a comparative approach, examines the legal bases for resorting to this executive guarantee through a descriptive-analytical method in the common law legal system. While providing the proposed legal principles of law by resorting to the existence premise and resulted rules and issues including rational promise, subordinate promise, and deprivation promise it can be proved that there is a real violation of the theory of mandatory implementation of early commitment in hypothetical violation in Shi'ite jurisprudence in order that the basis of this executive guarantee is identified, established and strengthened in the Iranian positive law.
