Lease Dispute Lawyer | What tenants and landlords each need to know
A lease dispute typically centers on one of three problems: the landlord won't return the deposit after the lease ends, the tenant won't vacate or pay rent despite the lease ending, or the two sides disagree over renewal, rent increases, or repair costs. Korean law gives tenants specific protections under the Housing Lease Protection Act (주택임대차보호법) and the Commercial Building Lease Protection Act (상가건물 임대차보호법), while also giving landlords lawful paths to terminate a lease and recover possession. Which side you're on, and which law applies to your lease, changes both the strategy and the timeline.
Lease Dispute | Three Common Fact Patterns
Lease disputes look different depending on who is asking for what. The remedy and the required documents differ significantly between a deposit claim, an eviction case, and a renewal/rent dispute.
| Who files | Tenant |
| Main remedy | Deposit return lawsuit / payment order |
| Key protection | Right to retain possession until paid (Art. 4) |
| Typical duration | 2-6 months if uncontested |
Tenants may exercise a lien-like retention right over the property until the deposit is repaid, and may also register a lease registration order to preserve priority after moving out (주택임대차보호법 제3조의3).
| Who files | Landlord |
| Main remedy | Lawsuit for termination and delivery of possession |
| Key trigger | Rent arrears reaching 2 months' worth (Art. 640, Civil Act) |
| Typical duration | 6-12 months including enforcement |
A landlord can terminate the lease once unpaid rent reaches two months' worth in total (민법 제640조), then must obtain a judgment before forcibly recovering possession — self-help eviction is not permitted.
| Who files | Either tenant or landlord |
| Main remedy | Renewal demand / rent adjustment claim / cost reimbursement claim |
| Key protection | Tenant's contract renewal demand right (Art. 6-3) |
| Typical duration | 1-4 months, often resolved without suit |
Tenants of residential units may demand one renewal for an additional 2-year term under statutory conditions (주택임대차보호법 제6조의3), while rent increases on renewal are capped at 5% (동법 제7조).
Lease Dispute | Deposit Return Disputes
The most common lease dispute is a tenant who has moved out (or is ready to move out) but hasn't received the deposit back. The correct next step depends on whether the tenant has already vacated the unit or is still living there.
Why timing of move-out matters
A tenant who vacates the unit and transfers their registered address before receiving the deposit back loses the protected priority status (Art. 3) that came from registering residence at the address. Before moving out, a tenant in this position should apply for a lease registration order (임차권등록명령) from the court, which preserves the same priority even after moving (주택임대차보호법 제3조의3). Without this step, a tenant who already moved may still sue for the deposit, but loses leverage against other creditors of the landlord.
Payment order vs. full lawsuit
If the amount and due date are undisputed, a payment order (지급명령) is a faster, lower-cost route than a full civil suit — the landlord has 2 weeks to object, and if they don't, it becomes enforceable like a judgment. If the landlord disputes the amount owed (e.g., claims deductions for repairs or unpaid utilities), the case usually needs to proceed as an ordinary civil lawsuit where those deductions become the central issue.
Landlord's right to deduct from the deposit
Landlords are not required to return the deposit in full if the tenant caused damage beyond normal wear and tear, or left unpaid utility bills. However, the landlord bears the burden of specifying and proving each deduction; a landlord who simply withholds the whole deposit without itemizing risks default interest and litigation costs if the case goes to court.
Lease Dispute | Termination, Eviction, and Rent Arrears
Landlords cannot forcibly remove a tenant or change the locks on their own, even if rent hasn't been paid for months. Recovering possession lawfully requires terminating the lease first, then obtaining a court judgment.
When can a landlord terminate for unpaid rent
For residential leases, the Civil Act allows termination once the tenant's unpaid rent reaches an amount equal to two months' rent in total, not necessarily consecutive months (민법 제640조). For commercial leases, the threshold is three months' worth of unpaid rent under the Commercial Building Lease Protection Act (상가건물 임대차보호법 제10조의8). Sending a formal notice of termination is a necessary step before filing suit.
The delivery-of-possession lawsuit
Once the lease is terminated, the landlord must file a lawsuit for delivery of possession (건물인도청구소송) rather than attempting self-help remedies such as changing locks or removing belongings, which can expose the landlord to criminal liability for forcible obstruction of business or intrusion. Only after obtaining a final judgment can the landlord apply for enforcement (강제집행) through the court's execution officer.
What a tenant facing eviction can raise
A tenant facing an eviction suit can dispute whether the arrears actually reached the statutory threshold, argue that partial payments were unfairly rejected, or raise a right to retain possession if a security deposit is still owed by the landlord. These defenses do not stop the case automatically but can affect the outcome and timing.
Lease Dispute | Renewal Rights and Rent Increase Limits
Renewal disputes usually come from residential tenants who want to stay longer, or landlords who want the unit back for their own use or a rent increase beyond the legal cap.
The tenant's one-time renewal demand
A residential tenant may demand renewal of the lease for one additional 2-year term by notifying the landlord between 6 months and 2 months before the lease ends (주택임대차보호법 제6조의3). The landlord can refuse only on limited statutory grounds, such as the landlord's own intent to occupy the unit or the tenant's own arrears of two months' rent or more.
5% cap on rent increases at renewal
When a lease is renewed under the statutory renewal demand right, any rent or deposit increase is capped at 5% of the previous amount (주택임대차보호법 제7조). This cap does not automatically apply to a completely new lease negotiated after the tenant chooses not to exercise the renewal right.
Lease Dispute | Commercial Lease Disputes
Commercial tenants face different issues than residential tenants — particularly around premium (권리금) recovery and longer renewal periods, since a business's location often carries real economic value beyond the lease itself.
Renewal period up to 10 years
Commercial tenants can demand renewal for up to a total lease period of 10 years from the original start date, under conditions similar to residential renewal (상가건물 임대차보호법 제10조). This gives long-term business tenants more stability than the shorter residential renewal term.
Protecting the right to recover key money (권리금)
During the final months of the lease, a landlord generally cannot obstruct the tenant's attempt to receive premium money from a new incoming tenant, and doing so without a legitimate reason can expose the landlord to damages (상가건물 임대차보호법 제10조의4). Disputes here often turn on whether the landlord's refusal to negotiate with the incoming tenant was justified under one of the statutory exceptions.
Lease Dispute | From Initial Consultation to Resolution
Bring the lease agreement, proof of the security deposit transfer, move-in/move-out dates, and any text messages or notices exchanged with the other party. Which party you are (tenant or landlord) and which law governs (residential vs. commercial) determines the strategy from this point.
Before filing suit, a formal written demand (내용증명) is usually sent — a deposit return demand, a rent arrears notice, or a termination notice — to create a clear record of the dispute timeline and often to satisfy a statutory precondition.
If there is a risk the other party will dispose of assets or the tenant will lose priority status, a provisional seizure or lease registration order may be filed before or alongside the main case.
Depending on whether the facts and amount are disputed, the case proceeds as a payment order, court-annexed mediation, or a full civil lawsuit including the delivery-of-possession or deposit-return claim.
If the other side does not comply voluntarily after judgment, enforcement proceedings (forced eviction, seizure of assets) are carried out through the court's execution division.
Lease Dispute | How Fees Are Calculated
Usually set based on the amount in dispute (the deposit amount or unpaid rent claimed) and the complexity of the case — a straightforward payment order costs less than a contested delivery-of-possession lawsuit.
If a success fee structure is used, it is typically calculated as a percentage of the amount actually recovered or the value of possession successfully restored, and is agreed upon in advance.
Filing fees are calculated based on the value of the claim under the Civil Procedure Fee Act, plus stamp fees and delivery costs for legal notices; these are separate from attorney fees.
If the case proceeds to forced eviction or asset seizure after judgment, additional execution officer fees and logistics costs (e.g., moving and storing the tenant's belongings) apply separately.
