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	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.	Semi-presidential government with a directly elected President focused on foreign and security policy, a Government answerable to the Seimas, and a separate Constitutional Court.	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.
How law is made	Bills pass both chambers of the Cortes Generales, with the Congress of Deputies able to override the Senate, and receive royal assent.	Bills are adopted by the Seimas and signed by the President, who may veto and return a bill for reconsideration.	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.
Legal profession	Abogados belong to local bar associations (colegios de abogados); procuradores represent parties procedurally and notaries authenticate deeds and company acts.	Advocates belong to the Lithuanian Bar Association; notaries handle property, company and succession formalities.	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.

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.
