In the legal system of Iran and Imamieh jurisprudence, the marriage contract is customary, and its most important effect is the transfer of ownership, principally at the same time and with the conclusion of the contract. However, the guarantee may be left to the seller (in the surrender) and the buyer (in the surrender). This guaranty is the same guarantor. Compulsory bond is an obligation to pay a certain remuneration in exchange for a deductible payment and vice versa, which is only made in a negotiated agreement. This rule does not apply to the plaintiffs, and can be extended to the case of Thaman and other exchanges other than Bāyī. The obligatory guarantor and its relation to the concept of surrender and acceptance or commitment by a committed person is one of the most important issues regarding the rights of obligations. The transfer of ownership in a custom-made contract, the main purpose of which is an agreement, is, in fact, when it is possible to realize that the seller is in a position where the acquisition of ownership and the exercise of the owner's right by it is possible by the buyer. Among these issues, the jurisprudential rule of "wasting before the bill" has long been one of the challenges and differences between jurists and jurisprudents, and sometimes it has been confused between these concepts and their effect on each other. In this paper, we first look at and analyze the relationship between submissive submission and transfer of ownership, and in this passage we will become acquainted with the concept of collateral warranties, and then we will examine the rule of "premature debt before the bill" and its attribute in various assumptions. We try to do this. We explain the narrative so that scientific analysis of concepts such as submission and transfer of curfew can be better done.
