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.	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, with a highly asymmetric structure: 23 provinces, five autonomous regions, four directly administered municipalities and two special administrative regions. Hong Kong and Macao operate under 'one country, two systems' with their own Basic Laws, their own courts of final appeal, and legal systems that remain common-law and Portuguese-derived civil-law respectively. Provincial people's congresses may enact local regulations that must not contravene national law.
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 are adopted by the Seimas and signed by the President, who may veto and return a bill for reconsideration.	The NPC meets in plenary once a year, so the Standing Committee enacts most legislation. A bill is normally read three times under the Legislation Law, with drafts published for public comment — the Civil Code drafts drew over a million submissions. The NPCSC also has power to interpret laws, which it exercises as a substantive lawmaking tool. There is no presidential veto: the President promulgates what the NPC or its Standing Committee has passed.
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.	Advocates belong to the Lithuanian Bar Association; notaries handle property, company and succession formalities.	Lawyers are licensed under the Lawyers Law after passing the National Unified Legal Profession Qualification Examination, which since 2018 has also been the common entry route for judges, prosecutors and notaries. Firms are licensed and subject to annual inspection by provincial justice departments, and membership of the All China Lawyers Association is mandatory. A 2012 amendment to the Lawyers Law requires an oath that includes loyalty to the leadership of the Communist Party, and the annual licence renewal is the principal point of leverage over practitioners in politically sensitive work.

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.
