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	Unitary and decentralised, with twenty-five regional governments and the Lima Metropolitan Municipality holding elected councils and administrative competence. Peasant and native communities exercise jurisdiction within their territory under Article 149 in coordination with the justices of the peace.	Federal. Powers not expressly granted to the union are reserved to the 32 states (Article 124). States run their own civil, family and criminal-enforcement codes, but criminal procedure, labour and commercial law were federalised to produce single national codes.	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.
How law is made	Bills come from Congress, the executive, regional governments or citizens. A single chamber debates in committee and plenary; a second vote is required unless exempted. The President may observe a bill, and Congress insists by absolute majority. Constitutional amendment needs an absolute majority in two successive ordinary legislatures, or a two-thirds vote plus referendum.	Bills may be introduced by the President, either chamber, state legislatures or by citizens with 0.13% of the electoral roll. Both chambers must pass an identical text; the President may veto, and Congress overrides with two-thirds of each chamber. Constitutional amendments need two-thirds of Congress plus a majority of state legislatures (Article 135).	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.
Legal profession	A law degree followed by a bachiller and título de abogado, then compulsory registration with one of the departmental colegios de abogados, which hold disciplinary power. Registration in one college permits practice nationwide. Notaries are a separate profession appointed by competitive examination.	A law degree plus a cédula profesional from the Education Ministry licenses practice; there is no compulsory bar examination or single mandatory bar, which distinguishes Mexico from most of the region. Notaries public are a separate, strictly limited state-appointed profession with exclusive competence over real estate and company deeds.	Avocats admitted through the Ordre des avocats du Tchad; the profession is concentrated in N'Djamena.

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.
