Signing a Rental Contract in Korea: What to Check Before You Pay

Check the property register first

Before any money moves, get the property register extract (deungibu deungbon, 등기부등본). It is available to anyone from the Internet Registry Office for a small fee — you do not need the owner’s permission.

What to look for:

• Registered owner — must match the person signing. If someone signs on the owner’s behalf, ask for a power of attorney and the owner’s seal certificate
• Mortgages (geunjeodang, 근저당) — these may rank ahead of your deposit if the property is auctioned
• Seizures, injunctions, auction filings — any of these is a reason to walk away
• Total encumbrances plus your deposit against market value. If the sum approaches the value, deposit recovery becomes doubtful

Also pull the building register (geonchungmul daejang, 건축물대장) from Government24, free of charge. It shows whether the building is flagged as an illegal structure and whether the unit’s legal use is residential. A unit marked as a neighbourhood facility but rented as housing creates problems with loans and deposit guarantees.

Pull the register again on the balance payment day. Encumbrances registered between signing and completion are a documented pattern.

The agent and the fee

Most rentals go through a licensed agent (gongin jungaesa, 공인중개사).

Verify the licence. The office should display its registration, and you can check it with the local district office. An unlicensed intermediary leaves you without recourse and without the compensation scheme licensed agents carry.

Fees are regulated. Brokerage commission is set as a maximum percentage band determined by the transaction value and type, with the bands set by each metropolitan or provincial government. It is not freely negotiable upward, and both parties pay their own side.

Ask for the calculation in writing before signing. Round numbers that do not correspond to a percentage of the transaction value are worth questioning.

The agent must give you a confirmation of property explanation (jungaedaesangmul hwaginseolmyeongseo, 중개대상물 확인설명서) — a disclosure document covering the property’s condition and rights. Read it rather than filing it.

The contract itself

Contracts are in Korean and the Korean text governs. Have it read by someone you trust before signing.

Payment structure Typically a deposit (10% of the total deposit is common) at signing, and the balance on the move-in date. Do not pay the full amount at signing.

Pay into the owner’s own account. Transfers to an agent’s account or a third party are a recognised fraud pattern.

Terms to confirm

• Deposit and monthly rent amounts, and the payment date each month
• Contract period — two years is standard for residential leases
• Maintenance fee (gwanribi, 관리비) and what it covers
• Who pays for what repairs
• Whether the deposit is returned on the last day or after inspection

Special clauses (teugyaksahang, 특약사항) are where you protect yourself. Reasonable ones to propose:

• The landlord will not register new security interests on the property before the day after your move-in
• The contract may be cancelled with the deposit returned if a deposit guarantee application is rejected
• Existing defects noted and the landlord’s repair obligation stated

After signing

Three steps, in this order, ideally on move-in day.

1. Move in — take actual possession
2. Register your residence at the district office. As a foreign resident this is done alongside your alien registration
3. Get the fixed date stamp (hwakjeongilja, 확정일자) on the contract

Steps 1 and 2 give you the right to assert the lease against a new owner. Adding step 3 gives you priority for repayment out of sale proceeds if the property is auctioned.

Protection begins the day after these conditions are met, not the same day. A mortgage registered on your move-in day outranks you. Completing all three on the day you move, and checking the register that morning, closes most of the exposure.

Consider deposit return guarantee insurance. Given that a Korean housing deposit is often a multiple of an annual salary, pricing this before signing is a reasonable default. Application windows are limited, so ask early.

Keep the stamped original contract. You will need it for the deposit return and any dispute.
