Comparison
Read two legal systems against each other
Because every portal follows the same fifteen-section outline, the comparison is genuinely like-for-like rather than a collage of whatever each government happens to publish.

| Attribute | Saudi ArabiaReviewed | IranReviewed |
|---|---|---|
| Legal family | Islamic law | Islamic law with civil law codification |
| System of government | Unitary Islamic absolute monarchy | Islamic republic |
| Constitution | Basic Law of Governance | Constitution of the Islamic Republic of Iran |
| In force since | 1992 | 1979 |
| Capital | Riyadh | Tehran |
| Official languages | Arabic | Persian |
| Currency | Saudi riyal (SAR) | Rial (IRR) |
| Population | 36,900,000 | 89,000,000 |
| Division of powers | Unitary. Thirteen provinces headed by governors drawn from the royal family and appointed by the King, each with an appointed provincial council. No legislative competence exists below the national level. | Unitary, with 31 provinces headed by governors-general appointed by the Interior Ministry, alongside elected city and village councils created by the Constitution and operating since 1999 with limited competences. |
| How law is made | There is no legislature with power to enact law. Proposals originate in ministries or the Shura Council, are considered by the Council of Ministers, and take effect as royal decrees signed by the King and published in Umm al-Qura. The Shura Council may study and recommend but its resolutions require royal approval, and the King may legislate without consulting it. | A bill is introduced by the Government or by at least fifteen deputies, passes the Majlis, and goes to the Guardian Council, which has ten days, extendable, to find it consistent with Islam and the Constitution. If the Council objects, the bill returns for amendment; persistent disagreement goes to the Expediency Discernment Council, whose decision is final. Only then does the President sign and publish. |
| Legal profession | Advocates are licensed under the Code of Law Practice and must be Saudi nationals to appear in court, though licensed foreign firms may advise and now associate more freely following the 2024 opening. Judges are appointed from graduates of Sharia faculties by the Supreme Judicial Council and the King. Notarisation is a judicial function performed by notaries within the Ministry of Justice, and most commercial documentation must be executed in Arabic to be enforceable onshore. | Two parallel routes to practice, which is unusual and consequential: attorneys licensed by the Iranian Bar Association (Kanoon-e Vokala), a self-governing body dating to 1953, and attorneys licensed under Article 187 of the Third Development Plan directly by the judiciary. The two groups have contested each other's standing for two decades. Notaries operate licensed offices under the registration organisation, and their authentication is required for property transfers, marriage contracts and powers of attorney. |
A comparison table flattens nuance by design. Where a difference matters to a decision you are making, open both portals and read the section in full — the constitutional detail behind a one-line summary is often the part that governs the outcome.
