1. Mortgage / Mortgage to Secure Maximum Amount | Concept and Differences

The mortgage and the mortgage to secure maximum amount are concepts that are often confused within the real estate security system.
Both are security interests that allow a creditor to receive priority repayment through an auction when the debtor defaults.
However, there are important differences in the nature of the secured claim and in their effect.
Concept of a Mortgage
A mortgage is the right to receive priority repayment from real estate that the debtor or a third party has provided as security for an obligation, without transferring possession of that real estate (Article 356 of the 「Civil Act」).
It is established to secure a fixed claim, and when the claim is extinguished, the mortgage is extinguished together with it.
Concept of a Mortgage to Secure Maximum Amount
A mortgage to secure maximum amount is a mortgage established to secure an unspecified number of future claims that may arise from a continuous transactional relationship (Article 357 of the 「Civil Act」).
Its distinctive feature is that it secures claims that may arise from a transactional relationship, rather than a specific claim, within a certain maximum limit.
Objects
A mortgage and a mortgage to secure maximum amount may be established on the following rights (Article 371 of the 「Civil Act」).
∙ Superficies
∙ Jeonse rights
Characteristics
A mortgage takes effect only when it is registered.
∙ Principle of fixed priority (Articles 333 and 370 of the 「Civil Act」)
When several mortgages are established on the same real estate, priority is determined by the order in which the registrations were made.
∙ Right to request an auction (Article 363(1) of the 「Civil Act」)
If the debtor does not make repayment, the mortgagee may request an auction of the mortgaged property.
Differences
Category | Mortgage | Mortgage to Secure Maximum Amount |
Secured claim | A present, fixed amount | Unspecified future claims that increase, decrease, and fluctuate |
Accessory nature | Extinguished together when the present claim is extinguished | Maintained even if the secured claim is extinguished before the secured claim is fixed on the settlement date |
Effect of repayment | Repayment extinguishes the claim | Even if repayment is made, the claim is not extinguished if it is before the settlement period |
Registered amount | The amount of the secured claim | The maximum amount of the secured claim (even if the claim amount exceeds the maximum, there is no priority repayment right beyond the maximum amount) |
2. Mortgage / Mortgage to Secure Maximum Amount | Creation and Effect of a Mortgage

Among these two, the mortgage is a strong security system that uses real estate as collateral and allows the creditor to receive repayment in priority over the debtor.
To exercise it validly, certain requirements must be met, and its effect may extend to the fruits, substitute property, and accessories of the collateral.
Requirements for Creating a Mortgage
Because a mortgage is a real right, it is not created by a mere contract, and registration procedures must necessarily accompany it (see Article 186 of the 「Civil Act」).
A mortgage is validly created in law only when the following requirements are met.
- Mortgagee : must be the creditor of the secured claim
② Object of the mortgage
Only registrable rights may be the object of a mortgage
(real estate, superficies, jeonse rights, mining rights, fishery rights, automobiles, etc.)
③ Secured claim
In general, monetary claims arising from loans for consumption make up the majority, and future claims may also be included
Effect of a Mortgage
A mortgage grants a strong priority right over the collateral.
An established mortgage takes effect not only on the property itself but also on related profits, damages, substitute property, and the like, and it includes the following legal rights.
- The effect extends even to accessory things and appurtenances, fruits after attachment, compensation for public expropriation, and the like (Articles 358 through 370 of the 「Civil Act」)
② Effect on the secured claim
Principal, interest, penalty, damages, enforcement costs, and the like may be secured
However, only one year's worth of delay damages may be repaid in priority (Article 360 of the 「Civil Act」)
③ Right to priority repayment
The mortgagee may receive repayment in priority over other creditors through an auction (Article 363(1) of the 「Civil Act」)
Any portion not repaid through the mortgage may be claimed against other property as an ordinary creditor (Articles 340 and 370 of the 「Civil Act」)
Disposition and Extinguishment
Because a mortgage is a real right that secures a specific claim, by its nature there are certain limits on its free disposition, and it has the characteristic of sharing the fate of the claim.
Restrictions on the Disposition of a Mortgage
A mortgage cannot be transferred or provided as security separately from the claim it secures.
Accordingly, to transfer a mortgage to another person, it must necessarily be transferred together with the secured claim, in which case the provisions on assignment of claims apply, and a real-right agreement along with registration must be in place.
Extinguishment of a Mortgage
A mortgage is extinguished together with the claim it secured when that claim is extinguished.
However, a person who has established a mortgage on superficies or a jeonse right cannot extinguish the superficies or jeonse right without the consent of the mortgagee.
3. Mortgage / Mortgage to Secure Maximum Amount | How to Respond to Infringement of a Mortgage

Among these two, the mortgage is a strong security interest, but it may be exposed to outside infringement.
In such a case, the mortgagee can protect its rights through various rights under the Civil Act.
Real Right Claim
When a mortgagee is actually obstructed in its right or there is a concern that the right may be infringed, the mortgagee may claim the following (Articles 370 and 214 of the 「Civil Act」).
- Prevention of the infringement
- Security for damages
Right to Claim Damages
When an infringement of a mortgage is an unlawful act committed intentionally or through negligence, the mortgagee may claim damages (Article 750 of the 「Civil Act」).
▷ Obstruction of possession, etc.
A mortgagee who has suffered such an infringement may claim damages for a tort under the Civil Act.
Right to Request Replenishment of Collateral
When the value of the collateral has significantly decreased due to a cause attributable to the mortgagor, the mortgagee may demand that it be restored (Article 362 of the 「Civil Act」).
Right to Request Immediate Repayment
When the debtor intentionally damages or destroys the collateral, the mortgagee may request immediate repayment even before the due date arrives.
This is because, where the debtor has caused damage to, a decrease in, or destruction of the collateral, the debtor cannot assert the benefit of time (Article 388(1) of the 「Civil Act」).
