Looking for a Sublet in Seoul? 3 Risks You Must Know Before Signing

When you search for "Short-term housing in Seoul," you will often find posts on Facebook or Craigslist saying: "Take over my lease! Sublet available for 4 months."

It sounds perfect. No agency fees, flexible dates, and often fully furnished. But in Korea, subletting (known as Jeondae-cha / 전대차) can be legally dangerous if not done correctly.

Here are the three biggest risks you need to know.

Risk 1: The "Ghost" Contract

In Korea, it is illegal for a tenant to sublet their room to you without the landlord’s written consent.

• The Danger: If the actual landlord finds out you are living there without permission, they can kick you out immediately. You have no legal rights to stay.

Risk 2: The Deposit Disappearing Act

In a sublet, you usually send your deposit to the current tenant, not the landlord.

• The Danger: When the lease ends, the original tenant might disappear with your money. Since your name isn't on the original contract, the landlord has no obligation to return money to you.

Risk 3: The "Utility Bill" Bomb

In informal sublets, the original tenant often claims "utilities are cheap" or included, but verbal promises mean nothing. 

• The Danger: Korea’s floor heating (Ondol) can cost a fortune in winter. You might suddenly be demanded to pay huge heating or electricity bills that were not clearly stated in the contract, and you have no way to verify the actual usage.

The Safe Alternative

Don't rely on a stranger's promise. Use a platform that specializes in Short-Term Rentals where you sign a contract directly with the owner or a verified manager.
