The legal system of South Korea
A civil-law system that received German doctrine indirectly through Japanese codification during the colonial period, then absorbed substantial American public-law and procedural influence after 1948. The Civil Act of 1958 remains the core private-law statute. The defining institution is the Constitutional Court, created by the 1987 Constitution and sitting from 1988: it is a genuinely powerful tribunal that has struck down hundreds of statutory provisions, dissolved a political party, upheld one presidential impeachment and rejected another, and hears constitutional complaints directly from individuals.
Legal tradition
South Korea belongs to the civil law tradition. A civil-law system that received German doctrine indirectly through Japanese codification during the colonial period, then absorbed substantial American public-law and procedural influence after 1948. The Civil Act of 1958 remains the core private-law statute. The defining institution is the Constitutional Court, created by the 1987 Constitution and sitting from 1988: it is a genuinely powerful tribunal that has struck down hundreds of statutory provisions, dissolved a political party, upheld one presidential impeachment and rejected another, and hears constitutional complaints directly from individuals.
How power is divided
Unitary, with meaningful local autonomy under the Local Autonomy Act: 17 first-level divisions with directly elected governors, mayors and councils. Local ordinances must not contravene statute, and the central government retains extensive supervisory powers. There is no federal division of legislative competence.
Where law comes from
- The Constitution
- Supreme; enforced by a dedicated Constitutional Court.
- Statutes of the National Assembly
- The primary source of private and criminal law.
- Presidential decrees and ministerial ordinances
- Subordinate legislation, reviewable by the Supreme Court for legality.
- Treaties
- Article 6 gives duly ratified treaties the same effect as domestic law without further enactment.
- Supreme Court precedent
- Not formally binding, but departure is rare and a conflicting judgment is a ground of appeal.
The legal profession
Unified: an attorney-at-law (변호사) may appear at every level. Since 2009 the route is a three-year professional law school degree followed by the bar examination, replacing the old system of a single national examination and two years at the Judicial Research and Training Institute; the old route closed fully in 2017. Judges and prosecutors are now recruited from practising lawyers rather than straight from training. The Korean Bar Association regulates admission and discipline.

It has twice ruled on presidential impeachment.

E-series visas cover employment, D-series study and investment, and F-series long-term residence, with F-2 points-based residence and F-5 permanent residence.
- Employment & LabourA 52-hour weekly ceiling and dismissal only for just causeThe Labour Standards Act caps working time at 40 regular hours plus 12 overtime hours a week. Dismissal requires just cause, and an unfairly dismissed employee can seek reinstatement from the Labour Relations Commission.
- Tax LawProgressive income tax to 45 per cent with a local surtax on topPersonal income tax rises to 45 per cent, and a local income tax of 10 per cent of the national liability applies in addition. Corporate rates are graduated by income band.
- Business & CorporateCommercial Act company forms with chaebol-focused fair-trade rulesThe Commercial Act provides the corporate forms, with the chusik hoesa joint-stock company dominant. The Monopoly Regulation and Fair Trade Act imposes distinctive controls on large business groups.
- Criminal LawDeath penalty retained in law but unused since 1997The Criminal Act retains capital punishment, but no execution has been carried out since December 1997, making Korea abolitionist in practice. Jury-style participation exists only in an advisory form.
- Property & LandThe jeonse lump-sum lease, and registration that does not guarantee titleOwnership is registered, but Korean law gives the register no public warranty: a buyer must verify the chain of title. The distinctive jeonse tenancy takes a large refundable deposit instead of monthly rent.
- Family LawJudicial confirmation required even for divorce by agreementFamily matters are heard by specialist family courts. Even an agreed divorce needs judicial confirmation, and a statutory reflection period applies before it can be granted.
