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. The Legislative Assembly legislates for the whole kingdom, and the island divisions of Tongatapu, Vava'u, Ha'apai, 'Eua and the Niuas are administrative districts headed by governors. Below that, town and district officers are elected under the Fakafekau'aki and District and Town Officers Act.	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.	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	Bills pass three readings in the Legislative Assembly and require the King's assent, which is a real rather than purely formal step. Ordinary bills need a simple majority. Amendments to the Constitution require a majority in the Assembly at three separate readings and the consent of the King and Privy Council, and clause 79 forbids any amendment affecting the law of liberty, the succession to the throne or the titles and hereditary estates of the nobles.	Bills pass both chambers of the Cortes Generales, with the Congress of Deputies able to override the Senate, and receive royal assent.	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	Law practitioners are admitted by the Chief Justice and licensed under the Law Practitioners Act, with the Tonga Law Society as the professional body. Most qualify overseas or at the University of the South Pacific. A practitioner working on land must know the Land Act's allotment system rather than general property law, because the constitutional bar on selling land means conveyancing in the ordinary sense does not exist.	Abogados belong to local bar associations (colegios de abogados); procuradores represent parties procedurally and notaries authenticate deeds and company acts.	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.
