You are about to sign a favorable lease for an office or retail unit in South Korea, but the property register lists an unfamiliar “○○ Trust Co.” as the owner. The broker reassures you that “the original owner still runs everything.” Tenants who rely on that alone sometimes recover none of their deposit when the building is later sold at public auction.
In South Korea, the fate of a tenant of trust-held property depends on two things: whom you contracted with, and when the trust was created. In 2025 the Supreme Court of Korea issued a ruling that appeared to reverse the prior trend, sending ripples through real estate practice. The real estate disputes team at Atlas Legal lays out the key issues, following the case law.
1. Who owns trust-held property, and with whom should you sign a lease?
Once real estate is placed in trust, registered ownership passes fully to the trustee (the trust company). Because the trustee alone holds exclusive authority to manage and dispose of the property, a lease should, as a rule, be signed with the trustee.
Under the Korean Trust Act, a trust is an arrangement in which the truster (settlor) transfers property rights to the trustee to manage or dispose of for the purpose of the trust (Article 1 of the Trust Act). When ownership of real estate is registered in the trustee’s name, ownership passes to the trustee both internally and externally and is not retained by the truster. The trustee merely bears the limitation of managing the property within the purpose of the trust (Supreme Court of Korea, Apr. 12, 2002, 2000Da70460).
As a result, only the trustee holds exclusive authority over the trust property, and the authority to lease likewise rests with the trustee absent a special agreement (Supreme Court of Korea, Mar. 28, 2019, 2018Da44879, 44886). For a tenant, the safest course is to sign the lease directly with the trustee shown as the registered owner.
2. Is it safe to sign a lease with the truster (the original owner)?
In security trust (collateral trust) practice, the trust agreement often provides that “the truster leases the property in the truster’s own name with the trustee’s prior approval.” In that case the truster holds lawful leasing authority, conditioned on the trustee’s prior consent.
A lease falling under Article 3(1) of the Housing Lease Protection Act is not limited to leases signed with an owner-lessor; it also covers leases signed with a lessor who holds the lawful authority to lease even without owning the property (Supreme Court of Korea, Mar. 28, 2019, 2018Da44879, 44886). So if the trust agreement lets the truster lease with the trustee’s prior approval, and the truster actually obtained that approval, the lease is valid.
The decisive point is whether the trustee’s prior consent actually existed. A tenant contracting with the truster must check both the leasing clauses of the trust agreement and the trustee’s written lease consent (or lease confirmation).
| How the lease is signed | Trustee’s consent | Tenant’s position |
|---|---|---|
| Directly with the trustee | N/A | Safest — the trustee is the lessor |
| In the truster’s name, with prior consent | Yes | Lawful authority; lease is valid |
| In the truster’s name, no consent | No | Not enforceable against the trustee — deposit at risk |
3. What happens to a lease signed without the trustee’s consent?
Where the trust agreement requires the trustee’s prior approval but the truster leases without it, the lease cannot be asserted against the trustee. If that restriction is recorded in the trust register, the tenant cannot prevail and faces a high risk of losing the deposit.
Real cases show the danger clearly. Where a trust agreement provided that “any lease signed without the consent of the trustee and the priority beneficiary has no effect,” and that term was disclosed through the trust register, a court held the non-consented leases ineffective and even denied the small-sum tenants’ distribution in the auction (Changwon District Court Tongyeong Branch, Nov. 6, 2019, 2018Gadan28265). The tenants argued implied consent from long, unchallenged possession, but the court rejected it.
There is one avenue of relief. Even if the truster signed the lease without consent, if the truster later recovers ownership from the trustee, Article 3(1) of the Housing Lease Protection Act may apply to the lease from that point (Supreme Court of Korea, Mar. 28, 2019, 2018Da44879, 44886). If the tenant had already taken delivery and completed resident registration, the tenant acquires a perfected right the moment ownership returns, enforceable against later mortgagees or buyers.
4. Does the trustee succeed to the lessor’s position?
As a rule, even where the lessor (truster) places the leased property in a security trust after signing the lease, the trustee succeeds to the lessor’s position under Article 3(4) of the Housing Lease Protection Act (Article 3(2) of the Commercial Building Lease Protection Act).
The transferee of a leased home is deemed to succeed to the lessor’s position (Article 3(4) of the Housing Lease Protection Act), and “transferee” includes one who finally and conclusively acquires the right to lease. When ownership passes to the trustee by trust, the trustee succeeds to the lessor’s position, and this is not altered merely because the trust is a security trust for credit, or because the truster in substance handled the leasing while the trustee did not (Supreme Court of Korea, Apr. 12, 2002, 2000Da70460).
The difficulty arises where the trust agreement keeps the lessor’s position and the deposit-repayment liability with the truster and records this in the trust register. Whether that term binds the tenant is the central issue addressed next.
5. If the trust register says the truster repays the deposit, is the tenant at risk?
It depends on which Trust Act applies. For a trust created before July 26, 2012 (the former Trust Act), such a recorded term was enforceable against the tenant, so the tenant could claim the deposit only from the truster.
In a case governed by the former Trust Act, the Supreme Court held that where the trust agreement provided that “the truster leases in its own name with the trustee’s prior approval, and the truster bears the deposit-repayment liability,” and that term was recorded in the trust register, the term was enforceable against the tenant. As a result, the tenant could seek the deposit only from the truster as lessor, not from the trustee, and a third party (the auction buyer) who later acquired ownership from the trustee did not succeed to the lessor’s position either (Supreme Court of Korea, Feb. 17, 2022, 2019Da300095, 300101).
Under that reasoning, the tenant must pursue the deposit not from a solvent trust company but from a truster who has likely already lost its means — a deeply unfavorable position. Then, in 2025, in a case governed by the current Trust Act, the Supreme Court reached a different conclusion.
6. Why do the 2022 and 2025 Supreme Court rulings differ?
Because different statutes apply. Under Article 4(1) of the current Trust Act (fully amended July 25, 2011; in force July 26, 2012), terms recorded in the trust register cannot be asserted against third parties except for matters concerning the composition of the trust property.
Article 4(1) of the current Trust Act provides that trust registration lets a party assert “that the property belongs to the trust estate” against third parties. The Supreme Court read this to mean that only the fact that the trust property forms a trust estate independent of the trustee’s own assets can be asserted against third parties. So even where trust terms are recorded in the register and treated as part of the registry, nothing beyond the composition of the trust property can be asserted against third parties (Supreme Court of Korea, Mar. 13, 2025, 2023Da296643).
In that case the trust register stated that “the lease remains valid after the trust, the truster collects the rent, and the truster bears the deposit-repayment liability.” The Supreme Court held that such matters do not concern the composition of the trust property and therefore cannot be asserted against the tenant, reversing the lower court and ordering it to reconsider whether the truster had lost the lessor’s position. The same approach followed in Supreme Court of Korea, Feb. 13, 2025, 2022Da233164.
Notably, the Supreme Court squarely addressed the 2022 ruling (2019Da300095) and stated that it concerned a case under the former Trust Act and was not suitable to apply to a case governed by the current Trust Act. The two rulings are not contradictory; they are separate cases under different statutes.
| Issue | Former Trust Act, Art. 3(1) | Current Trust Act, Art. 4(1) |
|---|---|---|
| Trusts covered | Created on/before Jul. 25, 2012 | Created on/after Jul. 26, 2012 |
| Scope enforceable via trust register | Trust terms generally enforceable | Only the composition of trust property |
| “Truster bears the deposit” clause | Enforceable against tenant | Not enforceable against tenant |
| Leading cases | 2019Da300095; 2023Da310648 | 2023Da296643; 2022Da233164 |
For reference, the ruling on liability for management fees (Supreme Court of Korea, Jun. 5, 2025, 2023Da310648) did find that the trustee could assert the registered term against a third party — but that case, too, was governed by the former Trust Act. Under the current Trust Act, the outcome could differ following the March 13, 2025 ruling above.
So although the 2022 and 2025 rulings look to be in tension, the difference in fact stems from which statute applies. Because every newly created trust is now governed by the current Trust Act, the safer course in practice is to apply the latest ruling — the March 13, 2025 decision.
7. What should tenants — including foreign investors in the IFEZ — verify?
Before leasing trust-held property in South Korea, review both the real estate registry and the trust register, and check the lessor’s leasing authority, who repays the deposit, and when the trust was created.
In practice, a tenant should confirm the following:
- Review the registry and the trust register together — if the registered owner is a trust company, always obtain the trust register as well. It is part of the registry and available to anyone.
- Verify leasing authority — confirm whether the lessor is the trustee, or, if the truster, whether the trustee’s written consent exists. A contract with a non-consenting truster carries a high risk of deposit loss.
- Check the deposit-repayment party and the trust’s creation date — see whether the trust register contains a clause on deposit-repayment liability, and whether the trust was created on or after July 26, 2012.
- Confirm where the deposit is paid — where possible, pay the deposit to the trustee or the designated trust account and clarify who receives it.
Enforcement Rule Article 139-4 of the Registration of Real Estate Act (added Nov. 29, 2024) now requires the registrar, where the trust property is ownership, to annotate the trust registration with a notice that “when entering into a lease or similar transaction, one must review not only the registration certificate but also the trust register to confirm the purpose of the trust, the beneficiaries, and the management and disposal terms.” This underscores how essential the trust register is in trust property transactions.
This matters in particular for foreign companies and investors operating in the Incheon Free Economic Zone (IFEZ) — including Songdo International Business District, Cheongna International City, and Yeongjong International City — where many office and commercial buildings are held under security trusts. Reviewing the trust register and the trustee’s consent before signing is the most reliable way to protect a deposit.
Frequently asked questions
Q. With whom should you sign a lease for trust-held property in South Korea?
Once real estate is placed in trust, registered ownership passes fully to the trustee (the trust company), which holds the exclusive authority to manage and dispose of the property. As a rule the lease should therefore be signed with the trustee; to sign with the truster, you need the trustee’s prior consent under the trust agreement (Supreme Court of Korea, Apr. 12, 2002, 2000Da70460).
Q. Can you lose your deposit if you sign the lease with the truster?
If the truster leased the property with the trustee’s prior approval, the lease is valid because the truster held lawful leasing authority. But a lease the truster signed without the trustee’s consent cannot be asserted against the trustee, and where this restriction is recorded in the trust register, the tenant faces a high risk of losing the deposit.
Q. Is a lease signed without the trustee’s consent valid?
Where the trust agreement requires the trustee’s prior approval but the truster leases the property without it, the lease cannot be asserted against third parties. A court has even denied a small-sum tenant’s distribution on this basis (Changwon District Court Tongyeong Branch, Nov. 6, 2019, 2018Gadan28265). However, if the truster later recovers ownership from the trustee, the lease may gain perfected status from that point (Supreme Court of Korea, Mar. 28, 2019, 2018Da44879, 44886).
Q. Does the trustee succeed to the lessor’s position?
As a rule, even where property is placed in a security trust after the lease was signed, the trustee succeeds to the lessor’s position under Article 3(4) of the Housing Lease Protection Act (Article 3(2) of the Commercial Building Lease Protection Act). The fact that it is a security trust, or that the truster handled the leasing in practice, does not change this (Supreme Court of Korea, Apr. 12, 2002, 2000Da70460).
Q. Why do the 2022 and 2025 Supreme Court rulings reach opposite conclusions?
Because different statutes apply. Under Article 4(1) of the current Trust Act (in force July 26, 2012), even terms recorded in the trust register cannot be asserted against third parties except for matters concerning the composition of the trust property. So a clause assigning deposit-repayment liability to the truster cannot be asserted against the tenant (Supreme Court of Korea, Mar. 13, 2025, 2023Da296643). For trusts governed by the current Act, this latest ruling is the safer benchmark.
Q. What should foreign tenants and investors in the IFEZ verify before leasing trust-held property?
First, review both the real estate registry and the trust register. Second, confirm whether the lessor is the trustee, or, if the truster, whether the trustee’s written consent exists. Third, check who repays the deposit and the trust’s creation date to see whether the current Trust Act applies. Under Enforcement Rule Article 139-4 (added Nov. 29, 2024), trust registrations now carry a notice to review the trust register before any lease.
Trust-held property in South Korea cannot be assessed from the registry alone; protecting a deposit requires examining the trust register’s terms and the trust’s creation date.
