Posthumous reproduction (PHR) is the process by which assisted reproductive technology is used to establish pregnancy and produce genetic offspring following the death of a parent. There are different ethical and legal approaches towards this method of reproduction around the world. This paper will study the legality of PHR and its legal consequences for the family status of a child born by this technology according to Iranian law. This research uses the descriptive-analytical method to study Iranian legislation, the opinion of jurists and jurisconsults, and case law in the area of PHR. The only statute regarding assisted reproductive technology in Iranian law - the Embryo Donation Act 2003 - and the associated regulation contain no explicit provision on PHR. The subject is therefore very controversial among Iranian jurists and jurisconsults. This issue has also been the subject of divergent court decisions. This study shows that the current legislation is insufficient to address various issues raised by PHR, and there is a need for the legislature to provide legislative clarity. Although advocates of this technique use the approval of some jurisconsults (fuqahâ) as justification for the legal recognition of PHR during the idda period in Iranian law, some concerns regarding the practice, especially the child's best interests, support prohibition or at least restriction to specific, limited cases.
