Does registering my address on my ARC protect my rental deposit?

Yes, if you register the right address on time. A Korean tenant's deposit is protected against a new owner, a bank or an auction buyer only when two facts are on record: you live in the home, and your address is registered there. For a foreigner, that registration is the alien registration (외국인등록) and, after every move, the report of change of residence (체류지 변경신고). Korean immigration law says these replace a citizen's resident registration and move-in report (전입신고), so the housing protections apply to you in the same way. Add a fixed date stamp (확정일자) on your lease contract and you also gain a place in the payment queue if the home is ever auctioned.

What two protections can a tenant have?

Housing law gives tenants two separate rights. Many foreign tenants have the first without the second and only find out when something goes wrong.

Protection	What you need	What it does for you
Opposing power (대항력)	Living in the home + registered address	If the home is sold, the buyer steps into the landlord's place and must return your deposit
Priority repayment (우선변제권)	Opposing power + fixed date on the contract	If the home is sold at auction or by public sale, you are paid from the price before later creditors

Opposing power begins at the start of the day after you have both moved in and registered. In general, your place in the priority queue is set by whichever comes later: that day, or the date stamped on your contract.

How do I report a new address as a foreigner?

You have 15 days from moving in. Go to the community center (주민센터) for the new address, the city or district office, or the immigration office (출입국·외국인관서). Take:

• your alien registration card (외국인등록증); the officer writes the new address on the back and returns it
• the signed lease contract (임대차계약서) as proof that you live there
• your passport, in case the officer asks for it

If you use the mobile alien registration card, you can report through the online service and the new address is stored on the mobile card instead of being written on the plastic one.

Missing the deadline can lead to a fine of up to 1 million won. The bigger cost is that your deposit has no protection until the report is made. Any mortgage or seizure registered before then ranks ahead of you.

What mistakes cost foreign tenants this protection?

• Wrong or incomplete address. Copy the address from the property registry, including the building and unit number (동·호수). "Same building, near enough" is not safe in an apartment or multi-unit house.
• Registering where you do not live. A dormitory, an office or a friend's flat does not protect the deposit you paid somewhere else.
• Forgetting to report at all. People who move within the same city often assume the old report still covers them. It does not.
• Moving your registration out too early. If you take a job in another city and report the new address while the old landlord still holds your deposit, you can lose the old protection the next day.
• The contract is in your employer's name. When a small or medium-sized company rents a home for its staff, the protection applies once the employee chosen by the company moves in and registers. For other companies the position is less clear; ask before you rely on it.

Who gives the fixed date, and does it cost anything?

The fixed date is given by the community center, the registry office (등기소), a district court, or a notary. There is a small fee. Most tenants ask for it at the community center when they report the address, since the same lease contract is needed for both. It can also be requested online. The stamp goes on your original contract, so keep that paper safe and keep a scan of it on your phone.

Why does the move-in date matter so much?

Because your protection only begins at midnight after the report, while a bank's mortgage takes effect on the day it is registered. If the landlord borrows against the home on the same day you move in, the bank ranks first. Three simple habits reduce this risk:

1. Pull a fresh copy of the property registry when the balance of the deposit is due. 2. Report your address and get the fixed date on the moving day itself, not later in the week. 3. Ask for a special term in the contract: the landlord will not register a new mortgage or sell the home before your protection starts, and if this is broken you may cancel and get the full deposit back.

What if I hold an F-4 visa, or my visa changes?

Overseas Koreans who report a domestic residence (국내거소신고) instead of an alien registration are in a similar position. Courts have held that this residence report has the same effect as a move-in report for tenant protection, but check how it applies to your own case.

Extending your stay or changing to another status does not by itself touch your address registration, as long as the registration stays valid and you keep living in the home. Leaving Korea for good is different. You hand back the alien registration card at departure and the registration can be cancelled, which can end your protection. If your deposit is still with the landlord at that point, deal with it before you book the flight.

Next step

Check the back of your alien registration card today. Compare the address with the lease contract and the property registry, including the unit number, and make sure the contract carries a fixed date stamp. If anything is missing, fix it this week. If the landlord is already late with the deposit or the home is heading to auction, talk to a lawyer before you move out or change any registration. Consultations are paid; when you contact us, a staff member will call you back and explain the fee.
