What Happens If a Property Is Sold During a Lease in Korea?

Short Answer

If a property is sold during a lease in Korea, the lease does not automatically disappear.

In many cases, if the tenant has legal protection against third parties, the new owner may succeed to the landlord’s position. This means the new owner may become responsible for the lease relationship, including the obligation to return the lease deposit at the end of the lease.

However, the result can depend on the type of lease, whether the tenant satisfied and maintained statutory protection requirements, whether the sale was an ordinary sale or auction, and whether there are senior mortgages or other creditors.

Can a Landlord Sell the Property During a Lease?

Yes. A landlord can generally sell the property during the lease term.

A lease does not usually prevent the owner from selling the property. However, the sale can affect the tenant’s legal position, especially where the tenant paid a large lease deposit.

The key question is not simply whether the property was sold, but whether the tenant can assert the lease against the new owner.

---

Does the New Owner Become the New Landlord?

In many cases, yes.

If the tenant has opposability against third parties at the relevant time, the buyer generally succeeds to the landlord’s position by operation of law.

For residential leases, this generally depends on whether the tenant has satisfied requirements such as possession and proper resident registration. For foreign tenants, foreigner registration, address change reporting, or domestic residence reporting where applicable may have similar legal effect for this purpose.

For commercial leases, protection may depend on requirements such as delivery of the premises and business registration.

Because these requirements are fact-specific, tenants should not rely only on verbal explanations from the old landlord, new owner, or real estate broker.

Can the New Owner Demand That the Tenant Move Out?

Not automatically.

If the tenant has legal protection and the lease is valid against the new owner, the new owner generally cannot simply demand that the tenant vacate before the lease ends.

However, the answer may depend on:

• whether the tenant properly secured and maintained protection;
• whether the lease term has expired;
• whether the tenant has unpaid rent or other default issues;
• whether the property was sold by ordinary sale or through auction; and
• whether the lease is residential or commercial.

Foreign tenants should carefully review these issues before agreeing to move out or signing a new document with the new owner.

---

Who Must Return the Lease Deposit?

This is often the most important issue.

If the buyer succeeds to the landlord’s position, the deposit return obligation generally transfers to the buyer, and the former landlord is typically released from that obligation.

However, disputes can arise where:

• the tenant did not properly secure legal protection;
• the tenant lost protection before the transfer;
• the sale contract between the old and new owner did not clearly address the lease deposit;
• the property was sold through enforcement or auction;
• there are senior mortgages or other creditors; or
• the old landlord and new owner each deny responsibility.

In practice, tenants should confirm whether the deposit was taken into account in the sale and whether the new owner acknowledges the lease and deposit obligation.

Why the Real Estate Registry Matters

When a tenant hears that the property has been sold, the tenant should check the real estate registry.

The registry can help confirm:

• whether ownership has actually changed;
• when the transfer was registered;
• whether new mortgages or attachments were registered;
• whether the property is in auction or enforcement;
• whether the landlord named in the lease is still the owner; and
• whether there are other rights that may affect deposit recovery.

Foreign tenants should not rely only on a text message, broker explanation, or verbal notice from the landlord.

---

What If the Property Is Sold Through Auction?

Auction or enforcement sale can create different risks from an ordinary sale.

If the property is sold through auction, the tenant’s ability to recover the deposit may depend heavily on priority, timing, fixed date, statutory protection, and the amount recovered through the auction process.

In an auction, recovery often depends on whether the tenant satisfied opposability requirements, obtained a fixed date where required, and took necessary steps in the distribution process within the required timeline.

In some cases, a tenant may lose part or all of the deposit if senior secured creditors have priority.

For this reason, if the tenant learns that the property is subject to auction, foreclosure, attachment, or heavy mortgage debt, legal review should be conducted promptly.

---

Why Maintaining Protection Matters

It is not enough to have satisfied protection requirements once.

In some cases, the tenant may need to maintain the required conditions, such as possession or proper registration status, until the legally relevant point. If the tenant loses protection before the new owner acquires the property, the new owner may argue that the lease or deposit obligation is not enforceable against them.

If the tenant needs to move out before receiving the deposit, the tenant should consider whether additional steps, such as a leasehold registration order, are needed to preserve legal protection.

---

What Should Foreign Tenants Do After Learning About a Sale?

Foreign tenants should take practical steps early.

Key steps include:

• obtain an updated real estate registry;
• confirm whether ownership has changed;
• identify the new owner;
• preserve the lease agreement and deposit payment records;
• check whether statutory protection requirements were satisfied and maintained;
• confirm whether the new owner acknowledges the lease and deposit;
• avoid signing unnecessary documents without review; and
• seek advice if the landlord demands early move-out or refuses deposit responsibility.

If the deposit amount is large, early action is often important.

---

What Should Be Included in Communications with the New Owner?

If the new owner contacts the tenant, the tenant should communicate carefully and preserve records.

Important points include:

• confirmation of the lease term;
• confirmation of the deposit amount;
• confirmation of monthly rent, if any;
• confirmation of the intended move-out date;
• confirmation of the deposit return account;
• request for written acknowledgment of landlord succession; and
• preservation of all messages, emails, and notices.

Written communication is generally safer than verbal discussion only.

Conclusion

If a property is sold during a lease in Korea, the lease does not automatically disappear.

In many cases, a protected tenant may continue the lease against the new owner, and the new owner may become responsible for returning the lease deposit.

However, the result depends on the tenant’s legal protection, whether that protection was maintained, the type of sale, registry status, priority of rights, and the facts of the transaction.

For foreign tenants, the safest approach is to check the real estate registry, confirm whether the new owner has succeeded to the landlord’s position, preserve all lease and payment records, and avoid agreeing to move out or signing new documents without proper review.
