Renouncing of the Defects in Sold Goods in Islamic Jurisprudence and Iran Civil Law

Renouncing of the defects in sold goods is one of the important issues in the society. People face with this problem in their daily life, so it is very important to express the rules about it and the different aspects of it. Renouncing of the defects in sold goods refers to the situation in which the seller renounces the defects in the sold goods, it means that the seller declares that he is not responsible for the defects of the goods, or sells his properties with all defects. In this situation, if any defects appear, the buyer has no right to refer to the seller, and if the seller renounces a special defect then the buyer does not have the right to refer to the seller because of that defect. This study deals with the condition of renouncing the defects during contract and renewed defects, from the viewpoints of Shiite and Sunnite jurisprudence and the civil law and investigates the different aspects of it. Also, issues such as the situation in which the seller is the government; and writing the sentence on the door of stores expressing “No return”, have been investigated in order to find out that these cases mean renouncing of the defects or not.
