Commercial Premium (Key Money) Litigation Lawyer | What counts as a protected claim, and how to prove your loss
Commercial "premium" (권리금) is the value a tenant has built up in a location — customer base, business know-how, fixtures — that a new tenant is normally willing to pay for. Korean law does not guarantee a tenant will recover this money; it only obliges the landlord not to unfairly interfere with the tenant's attempt to collect it from an incoming tenant, within a defined window before the lease ends (상가건물 임대차보호법 제10조의4). Disputes usually arise when the landlord refuses to meet a prospective new tenant, demands an unreasonable rent hike to sabotage the deal, or claims an exemption that may not actually apply.

Commercial Premium (Key Money) Litigation | When does a landlord's conduct become an actionable premium claim?
A premium dispute is not simply 'the landlord didn't pay me key money.' It is built on specific statutory duties and exceptions. The cards below outline the conditions courts actually look at.
From three months before the lease term ends until the term actually ends, the landlord generally may not refuse to meet a new tenant the current tenant has arranged, demand rent or key money far above market rate from that new tenant, or otherwise obstruct the transfer of premium without justified reason (상가건물 임대차보호법 제10조의4 제1항). Whether a landlord's specific act — a sudden rent demand, silence, refusal to sign — counts as 'obstruction' is the central factual dispute in most cases.
The landlord is not liable if the incoming tenant cannot pay the rent the current tenant proposes, is deemed unfit to perform the lease (e.g. serious financial risk), or if the landlord takes back the space to run a similar business in good faith. The landlord's own reasons for refusing the new tenant are frequently litigated under this provision.
Premium protection does not apply to certain large retail spaces, spaces inside traditional markets already covered by separate rules, or leases of state/public property, among other listed exclusions. Confirming whether the leased premises falls into an excluded category is often the first thing to check before filing.
A tenant's claim for damages against the landlord's obstruction must be brought within 3 years from the end of the lease; missing this window generally bars the claim (상가건물 임대차보호법 제10조의4 제3항). This is separate from, and shorter than, general contract limitation periods, so timing needs to be checked carefully.
What this protection does NOT do
The statute does not force the landlord to pay premium directly, and it does not guarantee any particular tenant will actually be found. It only creates liability when the landlord's own conduct prevents the current tenant from collecting premium from a tenant the current tenant found. If no substitute tenant ever came forward, there is usually no claim regardless of how the lease ended.
Commercial Premium (Key Money) Litigation | What actually counts as landlord obstruction
Most disputes turn on whether the landlord's conduct crosses the line from ordinary lease negotiation into unlawful obstruction of the premium transfer.
Refusing to meet the incoming tenant
If the tenant introduces a specific, ready buyer and the landlord simply refuses contact or delays without explanation, this is one of the clearest fact patterns supporting a claim under 상가건물 임대차보호법 제10조의4 제1항 제1호. Documentation of the introduction attempt (texts, emails, witness statements) matters heavily.
Demanding an inflated rent or premium from the new tenant
A landlord who quietly demands a rent increase or a side payment from the incoming tenant that has no relation to market conditions can be found to have obstructed the transfer under 제10조의4 제1항 제2호·제3호. Comparing the new terms against the existing lease and nearby market rents is usually necessary evidence.
Timing: the 3-month window before lease end
The obstruction duty applies specifically from three months before the lease term ends. Conduct outside that window, or attempts to introduce a new tenant made too early or too late, can weaken the claim even if the landlord's behavior seems unreasonable.
Commercial Premium (Key Money) Litigation | Proving the loss and calculating damages
Even where obstruction is established, the tenant still has to prove how much premium was actually lost — this is usually the harder half of the case.
Damages are capped by the lower of two figures
Courts generally award the lesser of (1) the premium amount actually agreed with, or offered by, the substitute tenant, and (2) the premium level ordinarily recognized in that area at the time the lease ends (상가건물 임대차보호법 제10조의4 제3항). Without a concrete agreed figure from a real prospective tenant, damages become much harder to quantify.
Appraisal and market comparables
Where there was no finalized deal, tenants often rely on a court-appointed appraisal or comparable premium transactions in the same commercial district to establish a reasonable figure. This evidence needs to be gathered before or early in litigation, since it can take time to compile.
Whether the current lease term itself matters
A tenant's ability to claim premium recovery also depends on how long the tenant has occupied the space and whether the lease relationship is one the law recognizes for premium purposes; landlords sometimes argue the tenant's own history undercuts the claim. This is fact-specific and usually needs to be checked against the lease history.
Commercial Premium (Key Money) Litigation | From initial consultation to resolution
We review the lease, timeline of the landlord's conduct, and whether a substitute tenant existed or was actually prevented, to assess whether an obstruction claim is viable.
A formal written demand to the landlord often opens negotiation before litigation, and can also serve as evidence of the landlord's refusal if the case proceeds further.
If negotiation fails, a civil action for damages is filed, generally within the 3-year window from lease termination (상가건물 임대차보호법 제10조의4 제3항).
The case typically involves submitting comparable premium transactions, appraisal reports, and any records of the prospective tenant's offer to establish the damages figure.
Many premium cases settle once the evidence on both obstruction and valuation is laid out; where they don't, the court issues judgment based on the proven obstruction and the capped damages calculation.
Commercial Premium (Key Money) Litigation | How legal fees are typically structured
Set based on the complexity of the obstruction claim and whether a substitute tenant and appraisal evidence already exist, rather than a fixed rate for all premium cases.
Usually calculated as a percentage of the damages actually awarded or recovered through settlement, agreed upon before filing.
Court-appointed appraisal of the premium value, if needed, is billed separately from legal fees and depends on the scope of the appraisal.
Court filing fees are calculated based on the claimed damages amount and are paid in addition to attorney fees.
