What are the Legal Consequences of Fraudulent Marriage in South Korea?

1. Definition of Fraudulent Marriage 


A fraudulent marriage, also known as sham marriage or fake marriage, refers to a fraudulent union where the primary intention is not to form a marital partnership, but rather to deceive public administration or the community for specific purposes. 


These purposes may include obtaining apartment purchase eligibility, permanent residency, citizenship acquisition, or illegal stay. The marriage is registered falsely, without the genuine intent to establish a conjugal community.





2. Penalties for Fraudulent Marriage in the Republic of Korea


When a Fraudulent Marriage is discovered in South Korea, the consequences are twofold:


① Criminal Punishment for False Official Document Registration

Individuals who falsely register a marriage without genuine marital intent are subject to imprisonment or fines under Article 228 of the Criminal Act, which pertains to false entries in officially authenticated original documents.


It's worth noting that this provision applies not only to Fraudulent Marriages but also to other instances of false reporting, such as forging licenses or passports, that cause public officials to create inaccurate official documents.


② Revocation of Citizenship Acquired Through Fraudulent Marriage

Article 21 of the Nationality Act (Revocation of Permission, etc.) stipulates that those who obtain naturalization, reinstatement of nationality, or nationality retention judgment through fraudulent or other improper means may have their permission or judgment revoked. Consequently, individuals penalized for Fraudulent Marriages may face the additional consequence of losing their Korean citizenship.


Notably, the Ministry of Justice maintains a stringent stance on this issue, prioritizing the preservation of legitimate marriage practices even if citizenship revocation results in statelessness. This position is supported both internationally by the Convention on the Reduction of Statelessness and domestically through relevant Supreme Court decisions.




3. Removing Marriage Records from Fraudulent Marriages


Erasing marriage records resulting from a Fraudulent Marriage is only possible through a "Marriage Nullity Lawsuit". Such a lawsuit can be filed based on criminal complaints and conviction records for false entries in officially authenticated original documents.
