Quick answer: In Korea, if a commercial tenant falls two months’ rent (2기) in arrears, the landlord can terminate the lease and demand the property back — even before the lease term ends. In one case, we secured a full win for the landlord, including recovery of the building and unjust-enrichment compensation.
For foreigners who own or rent commercial property in Korea, lease disputes are among the most technical areas of law. Whether exactly “two periods” of rent are overdue can completely change whether the contract survives.
The complexity of terminating before the term ends
This case involved a tenant who stopped paying rent for two months while the lease term was still running. The landlord served notice of termination and sued for both the return of the building and unjust enrichment. When the lease still has time left, rent arrears become legally sensitive: whether the “two-period arrears” threshold is precisely met determines whether the contract can be ended at all. That meant scrutinizing every figure — the amounts, the deposit dates, and any deductible costs.
The core issue: did two-period arrears actually accrue?
The tenant argued they had paid part of the amount, so the two-period threshold wasn’t reached. But legally, arrears are only cleared when rent is paid in full — partial payment often has no real effect on the arrears calculation. We reviewed every payment, cross-checked transfer dates against receipt dates, and calculated the exact arrears period. The result showed the tenant’s “partial payments” had missed the actual deadlines, and the court accepted our position. This was the decisive winning point.
The law on termination and return of property
Under the Korean Civil Act (Article 640), a landlord may terminate a lease when the tenant is two periods of rent in arrears — because such arrears are treated as fundamentally destroying the trust the contract rests on. Here, the court found the two-period arrears clearly established, ruled the termination valid, and held that the tenant had to return the building. We won fully on the return-of-property claim.
Extending to unjust enrichment
Because the tenant kept occupying the building and operating their business even after termination, we claimed the value of that occupation as unjust enrichment. The court held that once the lease was lawfully terminated, continued occupation became unlawful, and accepted our claim in full — meaning the tenant had to return rent-equivalent amounts for that period. The landlord won completely on both the return of the building and the unjust enrichment claim.
Practical takeaways for landlords
Many landlords, mindful of the relationship, delay acting on arrears. But once two-period arrears are clearly established, termination and a return-of-property claim become legally available. The key is to keep clear records of rent payment history and notices — vague materials or verbal warnings are hard to prove in court. And if occupation continues after a termination notice, an unjust-enrichment claim should be considered.
Frequently Asked Questions
Q: Can a landlord in Korea terminate a lease for unpaid rent before the term ends?
A: Yes. Under the Civil Act, if a tenant is two periods of rent in arrears, the landlord may terminate the lease and seek return of the property, even during the lease term.
Q: Does a partial rent payment stop the arrears from counting?
A: Often not. Arrears are generally cleared only when rent is paid in full by the deadline. Partial payment after the due date may not affect the arrears calculation.
Q: What is a two-period (2기) arrears standard?
A: It refers to arrears equivalent to two rent periods (commonly two months). Once clearly established, it is a recognized ground for lease termination under Korean law.
Q: Can a landlord claim money for occupation after termination?
A: Yes. Continued occupation after a lawful termination can be treated as unlawful, and the landlord may claim rent-equivalent amounts as unjust enrichment.
Q: Does this apply to foreign landlords or tenants in Korea?
A: The rules generally apply regardless of nationality. Because the analysis is technical and proceedings run in Korean, representation is strongly advisable.
