What is jeonse fraud?

Jeonse fraud occurs when a landlord collects large lump-sum deposits from multiple tenants without the ability to return them. Common schemes include over-leveraged properties, fake landlords, and properties already facing foreclosure.

How can I check if a property is safe for jeonse?

Check the property registry (등기부등본) at iros.go.kr for 700 KRW. Look for mortgage amounts, liens, and verify the owner matches the landlord. If mortgages plus your deposit exceed 70% of market value, it's risky.

What is jeonse deposit insurance?

Jeonse deposit insurance (from HUG, SGI, or HF) guarantees your deposit return if the landlord defaults. It costs about 0.1-0.15% of your deposit annually and is the most reliable protection against jeonse fraud.

Jeonse Fraud Prevention Guide 2026: 7 Must-Check Items Before Signing a Lease in Korea

Jeonse fraud has become one of Korea’s most serious housing issues. Thousands of tenants have lost their deposits — sometimes their entire life savings — to fraudulent landlords.

The good news: most jeonse fraud can be prevented with proper due diligence before signing. Here are 7 critical checks every tenant should make.

1. Check the Property Registry

The property registry (등기부등본) is your most important tool.

How to Check

Visit iros.go.kr (Internet Registry Office) — costs 700 KRW
Check it on the contract signing day and again on move-in day

What to Look For

Section 갑 (Ownership): Verify the owner matches your landlord
Section 을 (Mortgages): Check for existing mortgages, liens, and seizures
Ownership history: Frequent ownership changes are a red flag

Red Flags

Mortgage amounts exceeding 60% of property value
Active seizures or liens
Corporate ownership or recent ownership transfers
Trust registrations (신탁등기)

2. Calculate the Gap Investment Risk

A “shell jeonse” (깡통전세) means the deposit plus mortgages exceed the property’s value.

Simple Formula

Risk = (Your deposit + Existing mortgages) ÷ Market value × 100

Below 70%: Relatively safe
70-80%: Proceed with caution
Above 80%: High risk — avoid
Above 100%: Shell jeonse — never sign

How to Check Market Value

Government real transaction prices at rt.molit.go.kr
Naver Real Estate, KB Real Estate price indexes
Ask 2-3 local real estate agents

3. Verify the Landlord’s Identity

Match their ID with the property registry owner
If a representative signs, require: power of attorney + seal certificate + phone call with owner
For corporate landlords: check corporate registry + business registration

4. File Resident Registration + Get Fixed Date

On move-in day:

Resident registration (전입신고): Establishes your legal occupancy rights
Rental transaction report (전월세신고): Automatically grants fixed date stamp
Fixed date stamp gives you priority claim on your deposit in foreclosure

5. Get Deposit Insurance

The most reliable protection available.

HUG (Housing & Urban Guarantee Corp) — most popular
SGI Seoul Guarantee — alternative option
Cost: approximately 0.1-0.15% of deposit annually
A 300 million KRW deposit costs about 300,000-450,000 KRW/year to insure

6. Verify the Real Estate Agent

Check registration at the Korean Licensed Real Estate Agents Association website
Confirm their office registration certificate is displayed
Verify they have indemnity insurance

7. Add Protective Clauses to Your Contract

Essential special clauses:

“Landlord shall not add mortgages between contract and move-in”
“Deposit shall be returned immediately if property is seized due to tax delinquency”
“Landlord shall cooperate with deposit insurance application”

If You Suspect Fraud

Re-check the property registry for new mortgages
Apply for tenant rights registration (임차권등기명령) at court
Contact the Jeonse Fraud Support Center (☎ 1533-8119)
File a police report if fraud is evident

Key Takeaway

Spending 30 minutes on due diligence can protect deposits worth tens of millions of won. Never rush into a jeonse contract, no matter how good the deal seems.
