Moral Foundations of Partie's Intent and Consent in Contracts and its Efficacy in Jurisprudence and Law

In ethics, it is a collection of social habits and religious teachings and independent judgments that make up the general conscience and are necessary to achieve perfection. In our legal system there are many debates about relation between jurisprudence and law with ethics, yet we do not answer to this question that what these rules and principles that cause this relation are. In this paper, we derived moral principles affecting the contracts by exploration of the verses and reports and Jurisprudential and legal resources. This method will have a great deal of importance in the accurate and secure application of the rules of the moral law in the field of contracts. Analyzing the ethical perspective, through the tools and techniques, and ethical imperatives of the fundamentals of the essential condition of the partie's intention and the consent of the parties indicate that the validity of this condition is rooted in moral principles and rules such as prohibition of possession in others property, compliance of action from intent, prohibition of coercion and violating the rights of individuals in social relations. Accordingly, the distinction between intention and consent is without reason, and lack of intent and defective consent caused by the reluctance and the mistake must lead to the invalidation of the contract.
