HUG Jeonse Deposit Guarantee Insurance Renewal Deadline: How Long Before or After Lease Expiration Can You Apply?
HUG jeonse deposit guarantee insurance does not automatically extend its coverage period simply because a jeonse lease has been renewed. Applications for guarantee coverage on a renewed lease are accepted from within 1 months before the original lease expires until before half of the renewed lease term has elapsed. The actual processing procedure differs depending on whether the tenant already has guarantee coverage.
In particular, the requirements differ depending on whether the jeonse deposit remains unchanged or increases. Meeting the application deadline also does not guarantee approval.

1. Does Jeonse Deposit Guarantee Insurance Automatically Renew When a Lease Is Extended?
Renewing a jeonse lease and extending the coverage period of jeonse deposit guarantee insurance are separate matters.
Even if the landlord and tenant agree to continue the lease for another 2 years, the guarantee period stated on the existing guarantee certificate does not automatically increase by 2 years.
Tenants who already have guarantee coverage must check the renewal procedure based on their renewed lease. Conversely, tenants who were not previously enrolled in guarantee insurance must undergo an eligibility review for new coverage.
These situations must be distinguished.
| Current Situation | What to Check |
|---|---|
| Existing guarantee coverage + lease renewal | Extension of the guarantee period and renewal review |
| No existing guarantee coverage + lease renewal | Eligibility for new guarantee coverage |
| Increased jeonse deposit | Recheck the increased amount and guarantee limit |
| Reduced jeonse deposit | Check the revised deposit and guarantee details |
HUG has announced changes to guarantee product names and the introduction of preliminary guarantee limit reviews for applications submitted from 2026-10-30. However, these changes do not mean that existing guarantees will be extended automatically.
2. Exactly When Does the Application Period for a Renewed Lease Begin and End?
HUG specifies the following application period for renewed leases under its general Jeonse Deposit Return Guarantee.
Applications may be submitted from within 1 months before the original jeonse lease expires until before 1/2 of the renewed lease term has elapsed.
Consider the following hypothetical lease.
Original lease expiration date: 2026-12-31
Renewed lease period: 2027-01-01–2028-12-31
Renewal term: 2 years
In this case, the general application window described by HUG begins around the end of November 2026, and the application deadline falls before the halfway point of the renewed lease term.
If the renewed lease lasts 2 years, this means the application must be submitted before approximately 1 year has elapsed. The exact deadline should be verified using the lease dates and HUG's date calculation rules.
There is an important distinction to keep in mind.
The Final Permitted Application Date Is Not Necessarily the Safest Time to Apply.
During the guarantee review, additional documents may be requested, or issues involving the property's legal rights may be discovered. Whenever possible, it is advisable to prepare the required documents and begin the process early after the renewed lease has been finalized.
In addition, the processing procedure for renewing an existing guarantee may differ from that for a new application. Tenants should therefore first contact the institution that issued their existing guarantee certificate.
3. Do You Need to Apply for an Insurance Extension After a Tacit Lease Renewal?
Even when a jeonse lease continues through tacit renewal, the extension of the guarantee period must be checked separately.
Tacit renewal occurs when a landlord and tenant do not provide notice of nonrenewal or changes to the lease terms within the legally prescribed period, causing the existing lease to continue under the same conditions.
Under South Korea's Housing Lease Protection Act, the duration of a residential lease renewed tacitly is deemed to be 2 years.
However, the fact that a lease legally remains in effect must be distinguished from HUG's recognition of a new guarantee period.
If your lease has been tacitly renewed, it is advisable to check the following.
1. The expiration date of the existing guarantee certificate
2. Documents that can establish tacit renewal
3. Whether the original jeonse deposit has changed
4. Documents required by HUG for guarantee renewal
The absence of a separately signed renewal agreement does not necessarily mean that guarantee renewal is impossible. The documents accepted and the applicable procedures should be confirmed with HUG or the financial institution that handled the guarantee.
4. If the Jeonse Deposit Has Increased, Can You Extend the Existing Guarantee Without Changing Its Amount?
If the jeonse deposit has increased, you must check whether the amount covered by the existing guarantee matches the deposit stated in the new lease agreement.
For example, assume the original deposit was KRW 200,000,000 and increased to KRW 220,000,000 upon renewal.
| Item | Amount |
|---|---|
| Original jeonse deposit | KRW 200,000,000 |
| Jeonse deposit after renewal | KRW 220,000,000 |
| Increase | KRW 20,000,000 |
| Percentage increase | 10% |
*The percentage increase was calculated as KRW 20,000,000 ÷ KRW 200,000,000 × 100.*
The fact that the existing guarantee certificate lists KRW 200,000,000 does not mean that the additional KRW 20,000,000 is automatically covered.
You must check whether the guaranteed amount needs to be revised to match the renewed lease and whether an additional review is required.
Under HUG's general Jeonse Deposit Return Guarantee, the eligible jeonse deposit must not exceed KRW 700,000,000 in the Seoul metropolitan area or KRW 500,000,000 in other regions.
However, being within these limits does not automatically qualify a tenant for coverage.
Additional requirements must also be satisfied, including those concerning the property's value, senior claims, legal rights associated with the property, and any restrictions on guarantees involving the landlord.
Conversely, if the jeonse deposit has decreased, you should check whether the guaranteed amount needs to be adjusted based on the revised lease amount.
5. What Documents Are Required When Renewing a Jeonse Lease?
The documents required for a guarantee renewal application may vary depending on the changes to the lease and the application channel.
The documents generally worth checking include the following.
| Document | Purpose |
|---|---|
| Original lease agreement | Verify the terms of the initial lease |
| Renewed lease agreement | Verify the revised lease period and deposit |
| Resident registration certificate | Verify registered residence and occupancy information |
| Existing guarantee certificate | Verify the original guarantee period and guaranteed amount |
| Proof of payment of the increased deposit | Verify that the additional deposit was paid |
| Additional lease-related documents | Review the contract, legal rights, and related matters |
This table is a preparation checklist, not a definitive list of documents required from every applicant.
In particular, supporting documents may differ between a renewal with no deposit increase and a renewal involving an increased deposit.
When preparing a renewal agreement, it is advisable to clearly record that the agreement extends the original lease, specify the revised lease period, and document whether the deposit has increased or decreased.
HUG's latest document submission requirements can be found in the Jeonse Deposit Return Guarantee application procedures on its official website.
6. Can a Guarantee Renewal Application Be Rejected?
Even if you previously held jeonse deposit guarantee insurance, problems may arise during renewal if you no longer meet the applicable guarantee requirements.
The main points to check include the following.
Whether the deposit and senior claims fall within the guarantee limit relative to the property's value
Whether the landlord's ownership or the property's legal rights have changed
Whether the renewed deposit meets the eligibility criteria for the relevant guarantee product
Whether the application deadline and document submission requirements have been satisfied
For example, even if the property's value and senior claims met the requirements when the original guarantee was issued, the review outcome may change if the property's value has since declined or new legal claims have arisen.
Therefore, previous enrollment alone should not be treated as assurance that renewal will be approved.
If an application is rejected or additional documentation is requested, the first step is to identify the specific reason. The appropriate response will depend on whether the issue involves missing documents, the guarantee limit, or the property's legal rights.
7. What Should You Do If the Application Deadline Has Already Passed?
If the standard application deadline has passed, the first step is to ask HUG whether any exception may apply.
Missing the deadline does not mean that the existing guarantee period is automatically extended or that coverage will be granted retroactively.
HUG's mobile guarantee guidance describes a separate application deadline exception for tenants in designated unsold housing management areas. However, whether the property is in an eligible area, whether the exception requirements are satisfied, and which leases qualify must be verified individually.
If you have missed the application deadline, the following steps are advisable.
1. Check the expiration date on your existing guarantee certificate.
2. Check the start and end dates of the renewed lease.
3. Ask HUG whether a deadline exception applies or whether renewal remains possible.
4. If renewal is difficult, check the eligibility requirements and conditions for guarantee products offered by other guarantee institutions.
Other institutions have their own application deadlines and review criteria, so this does not mean that alternative coverage will necessarily be available.
8. 3 Things to Check First Before Renewing a Jeonse Lease
If you are planning to renew a jeonse lease, it is important to review the lease terms and your existing guarantee status before applying for guarantee insurance.
First, Check the Expiration Date of Your Existing Guarantee Certificate.
You must distinguish between the lease expiration date and the guarantee period stated on the guarantee certificate.
Second, Check the Renewed Deposit Amount and the Property's Legal Rights.
Determine whether the deposit remains unchanged or has increased, and whether there have been any changes to the property owner or registered property information.
Third, Confirm the Renewal Procedure With the Institution That Handled Your Existing Guarantee.
The application method and required documents may differ between obtaining a new guarantee and renewing an existing one.
Ultimately, the key issue with HUG jeonse deposit guarantee insurance is not simply whether the jeonse lease has been extended.
What matters is confirming that the guarantee period has been properly extended to match the renewed lease term and that any changes to the deposit amount are reflected in the guarantee certificate.
If you have completed a lease renewal, take out your existing guarantee certificate and begin by comparing the guarantee period and guaranteed amount with your renewed lease.
