Jeonse hands over a huge lump-sum deposit, so one bad deal hurts badly. The good news: most jeonse fraud is preventable with a few checks before signing. With 2026's supply cliff pushing jeonse prices up, extra caution pays. Here's how to protect your deposit, in order.
Why jeonse fraud happens
The core risk is a "gaptong" home — where debt (deposit + loans) exceeds the home's value. If it goes to auction, a lower-priority tenant may not recover the full deposit.
| Type | Detail |
|---|---|
| Gaptong jeonse | Loans + deposit exceed value → loss at auction |
| Senior mortgage | Bank loan ranks ahead of your deposit |
| Fake landlord | Signing with a non-owner or name-lender |
| Trust property | Title held by a trust — no leasing right |
Before signing — the property register
The key check is the property register (deungibu). Pull it right before signing and again right before the balance payment.
| Check | What to look for |
|---|---|
| Owner | Is the signer the real owner? Any trust? |
| Mortgages | Senior loans — is loan+deposit too high vs value? |
| Seizure/auction | Any liens or auction filings → stop |
| Jeonse ratio | Higher deposit-to-value = more risk |

The three-part legal shield
Korean law protects tenants through resident registration + fixed date + actual occupancy.
| Tool | How | Effect |
|---|---|---|
| Opposing power | Move-in report + living there | Deposit claim survives owner change (from next day 0:00) |
| Priority repayment | Above + fixed date | Paid before junior creditors at auction |
| Top-priority | Small-deposit criteria | Portion paid first of all |
File your move-in report and fixed date the day you pay the balance. One day's delay can drop you behind a mortgage filed in between.
Deposit-return guarantee — the safety net
Still worried? Get a jeonse deposit-return guarantee (HUG/HF/SGI) — if the landlord can't return your deposit, the guarantor pays it.
| Item | Criteria (ex.) |
|---|---|
| Deposit cap | Capital region up to ~700M won / provinces ~500M (varies) |
| Eligibility | Rejected if senior loans / jeonse ratio too high |
| Timing | Apply before half the lease term passes |
| How | Apps (Naver Pay, Kakao Pay, Toss), ~5 min |
| Discounts | Youth/newlywed/low-income up to 50–60% off |
If a home can't qualify, that's itself a red flag. Add a "landlord cooperates with guarantee enrollment" clause to the contract. Premiums are modest — often around 0.1%+ per year, cheap for protecting a lump sum.
The order to follow
① Check the register for owner, mortgages, jeonse ratio → ② avoid gaptong homes → ③ sign with the real owner → ④ re-check the register before the balance → ⑤ file move-in report + fixed date on balance day → ⑥ enroll in a deposit-return guarantee.
Red-flag checklist
- ☐ Jeonse ratio far too high (gaptong risk)
- ☐ Large senior mortgage on the register
- ☐ Owner ≠ the person signing / trust title
- ☐ Suspiciously cheap and "sign fast"
- ☐ Guarantee enrollment is rejected
- ☐ Asked to delay move-in/fixed date
FAQ
When do I file move-in and fixed date?
The day you pay the balance. Opposing power starts the next day at 0:00; a fixed date adds priority. A day's delay can cost you.
Can any home get a guarantee?
No — homes with heavy senior loans or high jeonse ratios are rejected. Rejection is a warning sign.
What if the landlord changes?
With opposing power, you can claim the deposit from the new owner — so never delay your move-in report.
Jeonse fraud is about prevention, not luck. Register check → balance-day move-in and fixed date → guarantee. That order changes everything.
