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. The primary governing statute is the Commercial Building Lease Protection Act (enacted 29 December 2001), which establishes mandatory protections for commercial tenants regarding security deposits, opposing power, and priority repayment rights.
Deposit Limits
Commercial Bond Process in national
Negotiate Bond
Agree on bond type and amount during commercial lease negotiations.
Collect Security
Receive bank guarantee or cash bond before tenant takes possession.
Hold During Tenancy
Keep the bond securely for the full commercial tenancy duration.
Release or Claim
Return bond at lease end if no outstanding obligations, or make claims for documented breaches.
There is no statutory cap on commercial lease deposits in South Korea. Amounts are freely negotiated between the parties.
Establishing Opposing Power (Art. 3)
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 for leases within the statutory thresholds, the tenant must have:
- Opposing power (delivery + business registration)
- Fixed-date certification on the lease contract
The Commercial Building Lease Protection Act generally applies to commercial leases where the converted deposit (Deposit + Monthly Rent * 100) is below the specified regional thresholds.
For leases exceeding these thresholds, ONLY the following specific protections apply (Art. 2, Para. 3):
- Article 3: Opposing Power (Delivery + Business Registration)
- Article 10, Paras 1, 2, 3: Right to request contract renewal (up to 10 years)
- Article 10-2: Rent/Deposit increase or decrease based on market value (the 5% cap does NOT apply)
- Articles 10-3 to 10-7: Protection of Premium (Goodwill) recovery
- Article 10-8: Termination of lease for 3 months' rent arrears
- Article 11-2: Special case for termination due to COVID-19
- Article 19: Use of Standard Lease Form
Priority repayment rights (via fixed-date certification under Article 5) are NOT granted to tenants whose converted deposit exceeds the regional threshold. To secure priority in such cases, the tenant must register a 'Jeonse-gwon' (Right of Lease) or a mortgage on the property register.
Small-Amount Tenant Super-Priority
| Region | Deposit Threshold
| Super-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
- Certified notice — formal demand for deposit return
- Leasehold Registration Order — preserves rights if tenant must relocate
- Deposit return lawsuit — formal court proceedings
- Commercial Building Lease Dispute Mediation Committee — free pre-litigation mediation
Best Practices for Landlords
- Verify tenant's business registration status — determines when opposing power begins
- Plan deposit return funds — prepare before lease expiry
- Define restoration scope in the lease — specify what interior work must be removed
- Maintain a clear property registry — excessive encumbrances complicate priority rankings
