What to check
- Before signing: check the property register (owner’s name, mortgages) and ask about unpaid taxes and earlier tenants.
- Pay the down payment and rent only into an account in the landlord’s own name.
- On moving day: check the register again, then report your new address and get a fixed date — the same day.
- Report the lease within 30 days if the deposit is over ₩60 million or rent over ₩300,000 (rent report).
- Use the moving checklist so nothing is missed.
