South KoreaWhat happens if I don't register a real estate purchase?
If you don’t register a real estate purchase in South Korea, you do not acquire legal ownership—even if you paid in full—and cannot enforce your rights against third parties or the seller’s creditors.
What the Law Says
South Korean law requires registration to establish and protect real property rights. Without it, the buyer has only a personal claim—not real rights—against the seller.
Under the Real Estate Registration Act, ownership of land or buildings is only legally recognized after registration at the competent registry office. A sale agreement alone does not transfer title.
The Civil Act confirms that real rights—including ownership—arise only upon registration. Until then, the buyer holds only a contractual right (a 'claim') against the seller, which cannot be enforced against third parties such as creditors, subsequent buyers, or auction purchasers.
Failure to register also exposes the buyer to risk: if the seller goes bankrupt or sells the same property to another buyer who registers first, the unregistered buyer loses all rights to the property—even if they paid in full and took physical possession.

What to Do
Sign a written sales contract with the seller.
Submit a registration application to the local registry office (e.g., Seoul Regional Legal Affairs Office) within 30 days of contract execution.
Pay the registration tax (typically 1–4% of declared value) and registration fee (KRW 100,000 maximum late fee applies if delayed).
Obtain the certified registration certificate (‘Gijun Jangbo’), which serves as official proof of ownership.
