Iranian criminal law is mainly expressed through penal legislation and criminal procedure, with important foundations in Islamic law. Conduct can be criminal even when another country treats the same behavior differently. Iranian legal terminology distinguishes several broad punishment categories. These include fixed religious punishments, retaliation known as qisas, monetary compensation known as diya, and discretionary punishments known as ta’zir. Qisas and diya are especially associated with certain harms to life or body. In such cases, the rights and decisions of the injured person or victim’s family can have particular legal importance alongside the public proceedings. A criminal matter may begin with a complaint, police report, or official investigation. Investigators and prosecutors gather evidence, question relevant people, and decide whether the matter should proceed to a competent court. The court considers the accusation, evidence, applicable law, and defense. Depending on the case, a judgment may be reviewed through an appeal or another legally defined procedure. Evidence can include statements, witness accounts, documents, medical findings, expert work, physical material, and electronic records. The legal weight and admissibility of each item depend on the offense and procedural rules. A suspect or accused person should understand the accusation and obtain legal advice. Access to a chosen lawyer can be affected by the stage and type of proceeding, making early guidance from a lawyer experienced in Iranian criminal practice important. Public conduct, alcohol, drugs, sexual conduct, religious matters, political activity, photography, media, and online communications may carry risks unfamiliar to visitors. Avoiding assumptions based on foreign law is an important form of prevention.

The system combines enacted criminal rules with Islamic legal categories and principles. Anyone facing arrest, questioning, or a formal accusation should seek qualified legal assistance quickly.
Tip
If a criminal issue arises in Iran, remain calm, identify the authority and accusation, and request qualified legal assistance. Do not sign a statement you cannot read or verify. Preserve potentially helpful evidence without altering it or discussing the case publicly.
