Mortgage & Registered Mortgage (Geundangwon) Lawyer
Mortgage & Registered Mortgage (Geundangwon) Lawyer | Understanding priority, foreclosure, and disputes over secured claims
A mortgage (저당권) secures a fixed, already-determined debt against real estate, while a registered mortgage (근저당권, "geundangwon") secures a fluctuating maximum amount (채권최고액) for debts that may increase or decrease over time (민법 제356조, 민법 제357조). Both give the holder the right to have the property sold at auction and to be paid out of the proceeds ahead of unsecured creditors, but disputes commonly arise over the registered maximum amount, the order of registration, and whether the underlying debt still exists. Because Korean real estate almost always carries at least one geundangwon in practice, most disputes here are really disputes about how much is actually still owed and who gets paid first.
Mortgage & Registered Mortgage (Geundangwon) | Mortgage vs. Registered Mortgage (Geundangwon)
Korean law recognizes two related but distinct real-estate security devices. Which one applies to your case changes how the debt amount is proven and how foreclosure proceeds.
| Secured amount | Fixed at the amount actually registered |
| Typical use | One-time loans, installment sale security |
| Extinction | Ends automatically once the debt is repaid |
| Legal basis | 민법 제356조 |
Because the secured amount is fixed, repaying the underlying debt in full extinguishes the mortgage even without a separate cancellation registration, though cancellation should still be filed to clear the record (민법 제369조).
| Secured amount | Capped at the registered maximum (채권최고액), not the exact debt |
| Typical use | Revolving loans, ongoing business credit, rental deposits |
| Extinction | Survives partial repayment; must be formally cancelled or the debt relationship terminated |
| Legal basis | 민법 제357조 |
The registered maximum amount is not the same as the current outstanding debt — it is a ceiling that can be higher or lower than what is actually owed at any given time (민법 제357조 제1항).
Mortgage & Registered Mortgage (Geundangwon) | How Priority and Registration Order Decide Who Gets Paid
When a property is sold through auction, secured creditors are paid in the order their security interests were registered, not in the order the debts arose. Understanding this order is essential before lending against, buying, or leasing a property that already carries a registered mortgage.
Registration date fixes priority
Between multiple mortgages or geundangwon on the same property, the one registered earlier is paid first from the auction proceeds, regardless of when each loan was actually disbursed (부동산등기법 관련 등기 순위 원칙). A buyer or later lender should always pull the registry (등기부등본) before relying on the property as collateral.
The registered maximum amount does not equal the real debt
For a geundangwon, the 채권최고액 printed on the register is a ceiling, and the actual balance owed can be lower or, in rare cases involving accrued interest and costs, close to that ceiling (민법 제357조). This gap is one of the most common sources of dispute when a property changes hands or when a junior creditor calculates how much value is actually left for them.
Tenants with a deposit may compete for the same proceeds
A residential or commercial tenant who registered their lease or obtained a fixed date (확정일자) before a mortgage was registered can have priority over that mortgage for repayment of their deposit (주택임대차보호법, 상가건물임대차보호법). This is frequently disputed when a landlord grants a mortgage after a tenant has moved in but before the lease was properly dated.
Mortgage & Registered Mortgage (Geundangwon) | What Happens When the Debt Isn't Repaid — the Foreclosure Auction
If the secured debt falls into default, the creditor can petition the court for an auction of the mortgaged property rather than suing for money first (민사집행법 제264조). This is a court-supervised process, but it moves on its own timeline once started, and the debtor's options narrow as it progresses.
Filing the auction petition
The mortgage holder files a petition for a real-estate auction (임의경매) directly with the court where the property is located, attaching the registered mortgage or geundangwon and proof of the underlying default (민사집행법 제264조). Unlike a general money judgment, this route does not require a separate lawsuit to first establish the debt.
Appraisal, sale, and distribution
The court appraises the property, sets a minimum bid price, and holds the sale; after the sale is confirmed, proceeds are distributed to creditors according to their registered priority (민사집행법 제268조 등). A debtor who disputes the amount claimed must raise that dispute before distribution, since afterward remedies are far more limited.
Options before the auction concludes
A debtor can stop the process by repaying the debt (with the creditor's cooperation to withdraw the petition), negotiating a settlement, or in limited cases seeking a stay of the auction if there is a genuine legal defect in the underlying claim or the registration itself. Once the sale is confirmed, however, reversing it becomes very difficult even if a dispute over the debt amount later surfaces.
Mortgage & Registered Mortgage (Geundangwon) | Disputing the Debt Amount or the Validity of the Registration
Not every mortgage or geundangwon on the books reflects reality. Debts get partially repaid without the registration being cleared, guarantees get misdescribed, and sometimes a security interest is registered based on a forged or invalid document. These disputes require different evidence than a simple loan case.
Claiming the debt was already repaid
Where a mortgage secures a fixed debt that has been fully repaid, the debtor can demand cancellation of the registration and, if the creditor refuses, file a lawsuit for cancellation of the mortgage registration (근저당권말소청구). Bank transfer records, receipts, and any written settlement are the core evidence in these cases.
Challenging the actual balance under a geundangwon
Because a geundangwon secures a fluctuating balance up to a ceiling, disputes often center on how much is actually owed at the time of foreclosure or sale — the parties may need an accounting of principal, interest, and any agreed default charges to determine the true figure within the registered maximum (민법 제357조).
Attacking a forged or unauthorized registration
If a mortgage or geundangwon was registered using a forged power of attorney, a stolen seal, or without the true owner's consent, the registered owner can seek cancellation on the ground that the underlying registration is void, though this generally requires strong documentary or circumstantial proof given the presumption of validity that registered interests carry in practice.
Mortgage & Registered Mortgage (Geundangwon) | From Registry Review to Resolution
We start by examining the property registry (등기부등본), the underlying loan or credit agreement, and any repayment history to establish what is actually owed and how the security interests are ranked.
For creditors, this means assessing whether to proceed with a foreclosure auction or pursue a separate collection action; for debtors or buyers, it means identifying grounds to cancel, reduce, or delay enforcement of the registered claim.
We prepare and file petitions for real-estate auction, applications to stay or object to an ongoing auction, or lawsuits for cancellation of a mortgage registration, and represent you at each required hearing.
If the property is sold, we review the distribution schedule to confirm your claim was properly ranked and paid, and can raise an objection to the distribution if the calculation appears incorrect.
Many of these disputes resolve through a negotiated repayment plan, partial release of the registered amount, or a settlement that avoids the cost and delay of a full auction; we pursue this option in parallel when it serves your interest.
Mortgage & Registered Mortgage (Geundangwon) | How Fees Are Calculated
An initial review of the registry and relevant documents to assess whether the security interest is valid, what is actually owed, and what remedies are realistically available.
Set based on the complexity of the matter — whether it is a straightforward cancellation request, a contested auction, or a case involving allegations of forged registration — and on the value of the claimed amount or the property involved.
Where applicable, a portion of the fee may be tied to the amount recovered, saved, or successfully removed from a distribution schedule; this is agreed in advance and is never framed as a guaranteed outcome.
Auction petitions, appraisal fees, registration fees, and other statutory costs are billed separately as actual expenses (실비) incurred during the proceeding.
※ Costs vary depending on case complexity and specific circumstances; exact fees will be provided during consultation. No specific outcome is guaranteed.
Mortgage & Registered Mortgage (Geundangwon) | Self-Check Before You Act
1️⃣ For Lenders / Mortgage Holders
- Was the mortgage or geundangwon properly registered with the correct registered maximum amount?
- Has the debtor defaulted in a way that is clearly documented (missed payments, notice of default)?
- Are there earlier-registered security interests or tenant deposits that would be paid ahead of you?
- Do you have the original loan agreement and evidence of disbursement ready to attach to an auction petition?
2️⃣ For Debtors Facing Foreclosure
- Has the property already fully repaid the debt but the registration was never cancelled?
- Do you believe the amount claimed exceeds what you actually owe under the registered maximum?
- Has an auction petition already been filed, and do you know the case number and court?
- Are you exploring repayment, settlement, or a legitimate legal ground to stay the auction before the sale is confirmed?
3️⃣ For Buyers or Tenants Discovering a Registered Mortgage
- Did you check the registry (등기부등본) before signing the contract or moving in?
- Is there an existing geundangwon whose registered maximum amount could exceed the property's remaining value?
- If you are a tenant, did you obtain a fixed date (확정일자) or registration before or after the mortgage was recorded?
- Does the seller or landlord's disclosure match what is actually on the registry?
