The Law of Restitution: How South Korea Distinguishes Between Inherited Blood and Illicit Benefit

“Can a democratic constitutional state seize property from citizens based on the actions of their great-grandparents nearly a century ago? In South Korea, the answer is yes—provided that the state meets an exacting, legally rigorous standard that separates biological ancestry from identifiable illicit enrichment.”

1. The 1990s Real Estate Crisis and the Origins of the Special Act

During the 1990s, South Korean society was convulsed by a series of high-profile civil lawsuits. Descendants of notorious colonial figures—most prominently the great-grandsons of Lee Wan-yong and Song Byeong-jun—sued the state and private occupants to reclaim vast tracts of prime real estate in Seoul and Gyeonggi Province.

Under existing civil property law, the courts were forced to rule in favor of the descendants because the original colonial land registry deeds legally proved title. The spectacle of collaborator heirs reclaiming billions of won in real estate while descendants of independence martyrs lived in subsidized housing triggered an overwhelming national consensus for legislative intervention.

2. The Statutory Framework of the 2005 Special Act

In December 2005, the National Assembly enacted the Special Act on the Confiscation of Property of Pro-Japanese and Anti-National Collaborators to the State (친일반민족행위자 재산의 국가귀속에 관한 특별법).

The law established an independent statutory body, the Investigative Commission on Pro-Japanese Collaborators' Property, with sweeping authority to investigate real estate holdings and bank accounts. The core legal mechanism of the statute rests on a carefully defined statutory presumption:

3. The Constitutional Battle: Retroactivity and Property Rights

Descendants of collaborators challenged the law before the Constitutional Court of Korea, arguing that retroactive asset confiscation violated:

• Article 13(2) of the Constitution (Prohibition of retroactive deprivation of property rights);
• Article 13(3) of the Constitution (Prohibition of guilt by association / *Yeonjwaje*);
• Article 23 (Guarantee of private property).

In landmark rulings in 2011 and subsequent affirmations, the Constitutional Court upheld the law in its entirety. The Court ruled that because the 1948 Constitution declared the ROK as the successor to the anti-Japanese 1919 March 1st Movement and Provisional Government, properties acquired through the destruction of national sovereignty were unconstitutional at their inception. The state was not creating a new punishment, but restoring an original public title that was stolen from the Korean people.

4. Due Process and the Protection of Innocent Descendants

Crucially, the law does not permit arbitrary confiscation or hereditary punishment:

• Protection of Bona Fide Third Parties: If collaborator property was sold to third-party buyers in good faith (*Seon-ui Je-samja*), the property cannot be confiscated from the current innocent owner. Instead, the state pursues restitution of the sales proceeds from the collaborator's heirs.
• Preservation of Pre-1904 Ancestral Land: Farmland, burial mounds, and residences verified to have been in the family prior to 1904 remain fully protected as private ancestral property.

5. Restitution and the Funding of Independence Legacies

Between 2006 and 2010, the initial commission recovered over 13 million square meters of land valued at hundreds of billions of won. With the 2026 reactivation of the Commission, all proceeds from liquidated assets continue to be transferred directly to the Patriots and Veterans Support Fund.

This legal architecture demonstrates that South Korea's asset recovery is not an emotional witch-hunt or hereditary vengeance. It is a precise, constitutional instrument designed to ensure that material profit derived from national treason cannot be passed down across generations.
