A Review of Gender Reassignment in Iranian Law
For several years, the issue of gender reassignment has attracted serious attention in both Islamic jurisprudence and law, because a change in gender affects many legal rulings, including blood money, inheritance, custody, legal maturity, apostasy, and other related matters.
Legal Foundations of Gender Reassignment in the Iranian Legal System
Who Is Eligible to Apply for Gender Reassignment?
Under Iranian law, individuals who seek gender reassignment are classified into three categories. Before any surgical procedure, it must be determined which category the applicant belongs to, since authorization is issued based on this classification. This distinction is extremely important. For example, a person who undergoes gender reassignment in accordance with recognized medical standards may also apply to the competent court for correction of their birth certificate.
Physically Intersex Individuals
This group includes individuals who may possess both male and female sexual characteristics, sometimes with one being dominant over the other.
Another subgroup consists of individuals who outwardly appear to have only one sexual organ, but that organ is covered or obstructed by tissue, skin, or another physical condition.
Surgical intervention in such cases is intended to reveal or correct the existing sex and is not considered gender reassignment.
In physically intersex cases, the presence of recognized medical and legal indicators is required, and any intervention must be based on a physician’s diagnosis.
In individuals who possess both male and female organs, surgery is performed to remove one and strengthen the other.
Psychologically Intersex Individuals
In this group, the individual’s body is completely male or completely female, but their psychological identity and sexual inclination are inconsistent with their physical sex.
In some cases, incomplete biological characteristics may also exist. For example, a person may appear female but lack a uterus and not experience menstruation.
Although there are differing opinions regarding psychologically intersex individuals, surgery is only considered permissible when, according to a physician’s diagnosis, the person must be assigned to one of the two sexes.
Ordinary Individuals
This category includes individuals whose physical sex and psychological identity are consistent and who have no medical disorder, yet request gender reassignment. Surgery in such cases is not permitted for the following reasons:
First, preserving personal health is a legal and religious obligation, and without a justified medical reason, a person’s physical well-being may not be endangered.
Second, the nature of gender reassignment surgery is to treat a medical condition and remove a disorder. If a person is medically healthy, no physician has the authority to authorize such surgery. If a physician were to do so, it would constitute a medical offense and professional liability.
Inheritance of a Child After Gender Reassignment
All jurists and legal scholars agree that, in matters of inheritance, the individual’s gender at the time of death is determinative.
In other words, the person inherits based on the sex they have when they pass away. There is no significant disagreement on this point.
Inheritance Rights of Parents Who Have Undergone Gender Reassignment
With respect to parents who have changed their gender, two principal legal theories have been discussed:
- The first theory holds that parents who have undergone gender reassignment do not inherit from their children. However, since Iranian civil law does not recognize gender reassignment as an obstacle to inheritance, this view has limited support.
- The second theory maintains that such parents do inherit from their children, and that the basis of inheritance is the parent’s sex at the time of conception.
The first jurist to address the issue of gender reassignment surgery in Tahrir al Wasilah was Imam Khomeini. He stated in substance that if a father changes his gender, the person is neither considered the present father nor the present mother. If a mother changes her gender, the person is neither considered the present mother nor the present father of the children. He further noted that there is doubt as to whether inheritance should be based on the status at the time of conception, kinship, or whether no inheritance applies. He concluded that it is preferable to hold that inheritance does apply, with the determining factor being the time of conception, and that a recommended precaution is for the parties to reach a mutual settlement.
Frequently Asked Questions About Gender Reassignment in Iranian Law
Gender reassignment affects legal rulings related to blood money, inheritance, custody, legal maturity, apostasy, and other statutory matters, and must be carried out under legal and jurisprudential supervision.
Applicants are classified into three groups: physically intersex individuals, psychologically intersex individuals, and ordinary individuals. Surgery is not permitted for ordinary individuals who have no medical or psychological disorder.
No. When a person’s physical sex and psychological identity are consistent, and there is no medical condition, surgery is not permitted, because personal health must not be endangered without justification. Physicians are not authorized to perform such procedures.
Inheritance is determined based on the individual’s gender at the time of death.
Two views exist. Still, under Iranian civil law, gender reassignment is not considered an obstacle to inheritance. Many scholars hold that inheritance applies and that the determining factor is the parent’s sex at the time of conception, with reconciliation between the parties recommended as a precaution.

Is medical documentation usually the most important factor when someone applies for legal recognition?
Yes. Medical evaluations and expert opinions are generally central to the legal process because the court relies heavily on professional assessments before making a decision.
Are inheritance disputes common when family members disagree about how the law should apply?
They can be. Inheritance matters often become more complex when there are differing interpretations or family disagreements, which is why legal guidance is important.
Can a person change their identity documents immediately after surgery or is a separate legal process required?
A separate legal process is generally required. Individuals may need approval from the competent court before official records can be corrected.
The section about physically intersex individuals clarified a distinction that many people probably misunderstand. Is surgery in those cases viewed differently from gender reassignment under the law?
Yes. In certain intersex cases, surgery may be considered a corrective medical procedure rather than gender reassignment, depending on the medical findings and legal classification.
It was interesting to see how inheritance rules can still depend on specific legal theories. Have courts generally followed one interpretation more consistently than the other?
Courts analyze the applicable laws and legal opinions carefully, and the outcome may depend on the particular circumstances and arguments presented.
Is expert testimony commonly used if there is disagreement about a person’s classification?
Yes. Expert medical opinions can play a significant role when the court needs clarification regarding medical or psychological findings.
The point about ordinary individuals not being eligible for surgery under the legal framework was very clear. Could a physician face legal consequences for approving a procedure without proper justification?
Potentially yes. Medical professionals are expected to act within legal and professional standards, and unauthorized procedures may lead to liability.

Absolutely. Understanding the legal implications early can help individuals make informed decisions and avoid unnecessary complications later.
