Checklist to Avoid Jeonse Fraud

Key verification items to check before and after signing a jeonse contract, including registration documents, mortgages, guarantee insurance, special agreements, and residency reports.

A jeonse contract can put a large deposit at risk with just one mistake. Even if you find a home you like, it's crucial to verify the registration document, the owner, the mortgage status, the possibility of guarantee insurance, any special clauses, residency report, and deadline dates sequentially. This list compiles essential checks repeatedly emphasized by the Ministry of Land, Infrastructure and Transport, HUG, and local governments to prevent jeonse fraud, based on the key items you provided in the images.

Jeonse fraud can occur in various forms, not just one specific type. Situations such as when the landlord is not the actual owner, an excessive priority mortgage, not adequately explaining trust registration, or misleadingly presenting houses with difficult-to-pass guarantee insurance as safe can all mix together. Thus, it's important to cultivate a habit of checking at different stages—before signing, on the contract day, on the payment day, and right after moving in.

The purpose of this list is not to heighten anxiety but to provide a framework for you to ask the right questions. Rather than relying solely on whether the real estate agent assured you it was fine, ask yourself if you physically checked the registration document, if the deposit amount is reasonable compared to the market rate, if the necessary clauses are included in the contract, and whether you rechecked the rights changes after the final payment.

View Land Registration Certificate

Check the Registration Document

You can view the registration document even if you're not the landlord, so be sure to confirm it before signing the contract. It's essential to check whether the title's address matches the actual house address, whether the owner listed in the 'GAP-GU' matches your counterparty, and whether the mortgage and maximum claim amount in the 'EUL-GU' is excessively high compared to your deposit. It’s safer to verify this before signing the contract and again before making the final payment. If there's any ambiguity, don’t just trust the landlord’s explanation; it's better to verify through objective channels like registration data, guarantee agencies, or local government consultations.

Verify Owner and Contract Signer in Primary Registration

Verify the Owner in GAP-GU Against the Counterparty

The GAP-GU displays information related to ownership. If your contract counterparty differs from the registered owner, you’ll need to go through verification procedures like getting a power of attorney, seal certificate, or confirming with the landlord on the phone. Be especially cautious with contracts where the deposit is sent to an account not in the landlord’s name. It’s safer to verify this before signing the contract and also before making the final payment. If there's any ambiguity, don’t just trust the landlord’s explanations; verify through objective paths like registration data, guarantee agencies, or local government consultations.

Verify Priority Rights on Secondary Registration

Check Mortgages and Maximum Claims in EUL-GU

The mortgages in EUL-GU can be rights that may prioritize receiving payment before your deposit if the house goes to auction. It’s generally common to assess based on the maximum claim amount, not just the principal loan amount, so it's vital to consider the house price, deposit, and priority claims together. It’s safer to verify this before signing the contract and again before making the final payment. If there are any ambiguities, don’t just trust the landlord’s explanations; double-check through objective paths like registration data, guarantee agencies, or local government consultations.

Check Market Price and Deposit Ratio

Verify the Ratio of Market Price to Deposit

If the deposit amount is too close to the purchase price, there may be difficulty in getting the full deposit back in case of price drops or auction situations. It's advisable to set conservative standards, like the 80% benchmark shown in the image, to compare the purchase price, priority claims, and the total deposit together. It’s safer to verify this before signing the contract and again before making the final payment. If there’s any ambiguity, don’t just trust the landlord’s explanations; verify through objective paths like registration data, guarantee agencies, or local government consultations.

Confirm Eligibility for Rental Deposit Return Guarantee

Check Possibility of Guarantee for Deposit Return

Guaranteeing the return of the jeonse deposit can be a crucial safety measure when landlords fail to return the deposit. The conditions for joining guarantee insurance vary depending on the type of housing, deposit amount, priority claims, and landlord status, so it’s advisable to check the feasibility before contracting. It’s safer to verify this before signing the contract and again before making the final payment. If there are any ambiguities, don’t just trust the landlord’s explanations; verify through objective paths like registration data, guarantee agencies, or local government consultations.

Check Risk Level with Safe Lease App

Check Risk Using the Safe Jeonse App

The Safe Jeonse app offers various functions like housing price inquiries, risk assessments, landlord checks, jeonse contract self-tests, and applying for guarantees. It’s useful to quickly check basic risk factors when you find it hard to judge on your own before the contract. It’s safer to verify this before signing the contract and again before making the final payment. If there are any ambiguities, don’t just trust the landlord’s explanations; verify through objective paths like registration data, guarantee agencies, or local government consultations.

Verify Licensed Realtor and Brokerage

Verify Licensed Agents and Brokerages

Don't just rely on the business card of the agent; it’s advisable to confirm whether the brokerage is registered and if the actual office matches the contracting location. If you suspect unregistered brokerage or name borrowing, don't rush the contract and utilize local district offices or the brokerage inquiry function in the Safe Jeonse app. It’s safer to verify this before signing the contract and again before making the final payment. If there are any ambiguities, don’t just trust the landlord’s explanations; verify through objective paths like registration data, guarantee agencies, or local government consultations.

Include Prohibition of Registration Changes in Special Agreements

Include Prohibition of Rights Changes in Special Clauses

As shown in the image, including phrases like prohibition of rights changes before and after the final payment, and that violation will invalidate the contract and require the return of the deposit in the special clauses of the contract can help prevent disputes. However, the wording of special clauses can vary by situation, so it’s advisable to have important contracts reviewed by an expert. It’s safer to verify this before signing the contract and again before making the final payment. If there are ambiguities, don’t just trust the landlord’s explanations; verify through objective paths like registration data, guarantee agencies, or local government consultations.

Check for Trust Registration

Properties under trust can have discrepancies between the registered owner and the actual contractual authority, and this is frequently mentioned in cases of jeonse fraud. Without confirming trust documents, trust company consents, or the actual authority to contract, trusting only the landlord's word can be risky. It’s safer to verify this before signing the contract and again before making the final payment. If there are ambiguities, don’t just trust the landlord’s explanations; verify through objective paths like registration data, guarantee agencies, or local government consultations.

Check for Arrears in Taxes and Tax Certification

Check for Unpaid Taxes and Tax Certificates

The landlord's unpaid taxes can affect the retrieval of the deposit. Before the contract, it's advisable to request tax certificates or related confirmation procedures. If the landlord refuses to provide documents or gives unclear explanations, it’s safer not to rush the contract. It’s safer to verify this before signing the contract and again before making the final payment. If there are ambiguities, don’t just trust the landlord’s explanations; verify through objective paths like registration data, guarantee agencies, or local government consultations.

Immediate Processing of Change of Address Report and Confirmation Date

Process Residency Report and Confirmation Date Immediately

The residency report and confirmation date are key procedures for protecting the jeonse deposit. If you’ve paid the final amount and moved in, it’s best not to delay and handle it immediately. If possible, check ahead for the possibility of processing at the local community center or online according to the timing before and after the contract. It’s safer to verify this before signing the contract and again before making the final payment. If there are ambiguities, don’t just trust the landlord’s explanations; verify through objective paths like registration data, guarantee agencies, or local government consultations.

Reconfirm Registration the Day After Final Payment

Recheck Registration the Day After Final Payment

While everything may seem fine on the contract day, there can be risks of mortgage rights being set up around the final payment. Checking the registration document again the day after final payment to see if there are any changes in rights contrary to the special clauses can expedite post-response actions. It’s safer to verify this before signing the contract and again before making the final payment. If there are ambiguities, don’t just trust the landlord’s explanations; verify through objective paths like registration data, guarantee agencies, or local government consultations.

This list compiles general information regarding verification items that are easily overlooked before and after signing a jeonse contract. The actual risks can vary based on the property's rights relations, the deposit amount, any loans, and the landlord's situation. If there's even a slight ambiguity, don't rush into the contract; utilize the HUG Safe Jeonse app, check with a licensed real estate agent, seek legal counsel, or consult local government jeonse damage support services.

Especially, the jeonse deposit is one of the largest assets for most people. It might feel cumbersome to take an extra day to verify things before signing the contract, but quick processes like rechecking the registration documents or verifying the possibility of guarantee insurance can significantly reduce risks. If a landlord or agent avoids verification or pressures you to conclude the contract quickly, that can itself be a warning sign.

Ultimately, it’s also important to keep all documents and conversations recorded. Organizing the registration document viewings, contract, special clauses, payment history, and text and call records makes it much easier to respond if disputes arise. A safe jeonse contract begins with following through on verification procedures just as diligently as finding a good home.
