Commercial property deposits in South Korea follow many of the same principles as residential deposits but with key differences in how opposing power is established and how protection thresholds are calculated.

Deposit Limits

There is no statutory cap on commercial lease deposits in South Korea. Amounts are freely negotiated between the parties.

Establishing Opposing Power (Art. 3)

Delivery of premisesTenant takes physical possessionSame
Business registrationTenant registers a business at the premises with the tax officeResidential uses resident registration instead

Opposing power takes effect the day after the business registration application. Once established, the tenant can enforce the lease against a new owner if the property is sold.

Priority Repayment Rights

To obtain priority in foreclosure auctions, the tenant must have:

  1. Opposing power (delivery + business registration)
  2. Fixed-date certification on the lease contract

Priority repayment is available only when the converted deposit is below the regional threshold.

RegionConverted Deposit Threshold
Seoul₩900 million or less
Overcrowding Control / Busan₩690 million or less
Metropolitan areas₩540 million or less
Other areas₩370 million or less

Small-Amount Tenant Super-Priority

RegionDeposit ThresholdSuper-Priority Amount
Seoul₩65 million or less₩22 million
Overcrowding Control / Busan₩55 million or less₩19 million
Metropolitan areas₩38 million or less₩13 million
Other areas₩30 million or less₩10 million

Deposit Return

  • Deposit return and premises surrender are simultaneous obligations
  • No separate statutory return deadline
  • Landlord may deduct unpaid rent, restoration costs, and other agreed charges

Remedies for Non-Return

  1. Certified notice — formal demand for deposit return
  2. Leasehold Registration Order — preserves rights if tenant must relocate
  3. Deposit return lawsuit — formal court proceedings
  4. Commercial Building Lease Dispute Mediation Committee — free pre-litigation mediation

Best Practices for Landlords

  1. Verify tenant's business registration status — determines when opposing power begins
  2. Plan deposit return funds — prepare before lease expiry
  3. Define restoration scope in the lease — specify what interior work must be removed
  4. Maintain a clear property registry — excessive encumbrances complicate priority rankings
