"Nahleh" is one of the financial rights that has been provided for the wife in Imami jurisprudence and subsequently in Iranian law. This institution was recognized by the legislator in 1992 in order to provide financial support to the wife and to achieve more justice for women in paragraph (b) of Note 6 of the Law on Amending Divorce Regulations, which can be defined in a short and useful definition. He considered the payment of a sum by the husband to the wife at the time of the divorce. In the latest developments in the field of family law, the legislature in 2012 repealed the law amending the provisions related to divorce. Nevertheless, the institution of "Nahleh" is considered an exception to this version, and as a result, the legislature has still upheld its provisions. Given these developments in the legislative process of this protectionist institution and the ambiguities and conflicts that have occurred in the concept of Nahla in the jurisprudence, the present article intends to respond to the contradictions in the jurisprudence and provide suggestions in this regard. The results of the research also show that Nahleh is a suitable institution for financial support of the wife; However, due to the uncertainty of its position and basis, especially in the judicial procedure, it does not have the necessary function as it should.
