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.

Population	89,000,000	20,000,000
Division of powers	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.	Unitary. Seventeen regions (oblasts) and three cities of republican significance — Astana, Almaty and Shymkent — each headed by an akim appointed by the President. Local representative assemblies (maslikhats) have limited competence. Overlaid on this is the Astana International Financial Centre, a territorially delimited zone with its own court, arbitration centre, regulator and body of law that operates outside the national legal order.
How law is made	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.	Bills are introduced in the Mazhilis by deputies or the Government, and must pass the Mazhilis before going to the Senate. If the Senate rejects a bill it returns to the Mazhilis, and a joint commission may be convened. The President may veto, and an override requires two-thirds of each chamber. The President may also declare a bill urgent, requiring consideration within a month, and may issue decrees with the force of law where Parliament has delegated that power. Laws enter force ten days after official publication unless otherwise stated.
Legal profession	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.	Advocates are licensed under the Law on Advocacy and Legal Assistance 2018, which introduced mandatory membership of regional bar collegia coordinated by the Republican Bar Association, and separated advocates from other legal-services providers who must register separately. Entry requires a law degree, an internship and a qualifying examination. Notaries are a distinct licensed profession whose involvement is compulsory for many real-estate and corporate transactions. Practitioners in the AIFC Court are registered separately and may be foreign-qualified.

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.
