I need to leave Korea for a new job and break my apartment lease a year early — what does Korean law say I owe, and can the landlord keep my deposit?

"Rent until the end" is the starting point in contract terms, but it is not what a tenant who leaves early usually ends up paying, because Korean practice and the landlord's own duty to limit his loss work against it. In the ordinary case, the tenant remains liable for rent only until a replacement tenant moves in, the landlord must accept a suitable replacement, and the tenant customarily bears the agent's fee for finding one. The deposit is security, not a penalty: the landlord may deduct rent actually unpaid and documented damage, and must return the rest. What you do in the next two months — and what you get in writing — decides whether this is a clean exit or a fourteen-month argument.

What this is under Korean law

A fixed-term lease binds both parties for its term; a tenant has no unilateral right to terminate a two-year residential lease early unless the contract provides one or the landlord agrees. The Housing Lease Protection Act (주택임대차보호법, jutaek imdaecha boho-beop) gives tenants a right to terminate on three months' notice in one situation — where the lease has been renewed by implication after its term — which is not yours. So, strictly, the landlord may insist on the contract.

What limits that in practice: the landlord's duty under the Civil Act's general principles to mitigate his loss, which Korean courts apply to leases by holding that a landlord who unreasonably refuses a replacement tenant cannot claim rent he could have received; the custom, widely followed and generally upheld, that an early-leaving tenant pays rent until a replacement is in and bears the brokerage fee for that replacement; and the fact that Seoul apartments at market rent re-let within weeks, not months. A landlord's claim for "fourteen months" is a claim he could only maintain by keeping the apartment empty, which a court would not reward.

The deposit

The deposit secures your obligations; on termination, the landlord returns it less unpaid rent, utilities and the cost of repairing damage beyond ordinary wear, with the burden on him to prove damage. He cannot retain it "for the remaining months" if a replacement tenant has moved in and the rent is being paid. If he does, the remedy is a demand and, if necessary, a payment order (지급명령, jigeup myeongnyeong) — and, as a departing tenant, the lease registration order (임차권등기명령, imchagwon deunggi myeongnyeong) that keeps your priority attached to the property after you move out and deregister, so that the claim survives your departure.

The right way to leave

Get his agreement to early termination in writing, conditioned on a replacement tenant: the date you vacate, that you pay rent until the replacement's move-in date, that you bear the agent's fee, and that the deposit is returned less specified deductions within a set period after move-out. Landlords who have said "rent until the end" agree to this routinely once it is written down, because it is what actually happens and because the alternative — a departed tenant, an empty apartment, and a lawsuit for rent — is worse for them.

Then market the apartment now, with the agent, at the current rent; two months is enough. Document the apartment's condition on move-out with dated photographs and, if possible, the landlord's or agent's signature on a condition checklist.

Your situation as a foreign national

Leaving does not end either your obligation or your rights; a landlord could pursue unpaid rent against your Korean account or, in principle, abroad, and you can pursue the deposit from Singapore through counsel under a power of attorney (위임장, wiimjang) signed before you go. Keep the Korean account open for the deposit's return, and keep your foreign registration until the lease is actually terminated where you can.

What to do now, and what not to do

Do not simply stop paying and leave; that converts a manageable exit into a debt. Do not accept a verbal "I'll return the deposit later." Do: written termination terms, replacement tenant, condition photographs, power of attorney, and — if the deposit is not returned on the agreed date — the registration order and the demand, through counsel.

Practical insight

Departing foreign tenants overpay in one of two ways: they accept the "rent until the end" framing and let the landlord keep the deposit, or they leave without a written agreement and then find the landlord has re-let the apartment in three weeks and kept fourteen months' worth anyway. The written agreement conditioned on a replacement is the whole solution; it costs a page and it is what the law would produce after a year of litigation.
