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.

Division of powers	Presidential system with a Prime Minister, a bicameral Parliament of National Assembly and Senate under the 2023 text, and a judiciary headed by the Supreme Court.	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.	A constitutional monarchy with the King as head of state, an executive led by the President of the Government, a bicameral parliament and an independent judiciary, overlaid by extensive regional self-government.
How law is made	Bills are examined in committee and plenary and passed by the legislature, then promulgated by the President. The Constitutional Council may be seised before promulgation.	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 pass both chambers of the Cortes Generales, with the Congress of Deputies able to override the Senate, and receive royal assent.
Legal profession	Avocats admitted through the Ordre des avocats du Tchad; the profession is concentrated in N'Djamena.	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.	Abogados belong to local bar associations (colegios de abogados); procuradores represent parties procedurally and notaries authenticate deeds and company acts.

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.
