When I moved from considering officetels to evaluating commercial property, I first studied title and rights due diligence.
I learned to read Korean property registers for ownership, mortgages, and other claims, and looked into civil, registration, and tax law. Before committing a substantial amount of money, I wanted to understand what a buyer could actually verify.
One discovery was especially surprising.
Even an official property register does not guarantee title
A Korean property register is one of the first documents a buyer examines. It records the registered owner and various rights attached to the property.
I had assumed that checking this official record and completing an ordinary purchase would necessarily protect the buyer's title.
But Korean property registration has no public faith. The register may support a presumption that its entries reflect true legal rights, yet reliance on a defective entry does not automatically create a valid ownership right.
An inheritance dispute made that distinction vivid.
Heirs discovered later—and a buyer who had already paid
In a 21 April 2017 first-instance judgment, Changwon District Court Masan Branch, 2016Gadan10561, a property owner had died in 2015. A child recorded in the family register had registered the inheritance alone, then sold one property to a third party for KRW 130 million. The purchaser completed the transfer registration.
Four additional biological children were subsequently confirmed. Born during another de facto relationship, they had been registered as the children of a different person. A court judgment confirming their parent-child relationship became final in 2016.
The trial court ordered cancellation of the purchaser's registration for the four-fifths share exceeding the seller's inheritance portion. The purchaser's lack of knowledge of the other heirs did not overcome the absence of public faith in registration.
That judgment shocked me. Someone who had checked the official record and paid for the property appeared to risk losing most of it because of a family relationship that would have been difficult to discover.
But there was an important appeal.
The 7 December 2017 appellate judgment, Changwon District Court, 2017Na2155, reversed the cancellation order against the buyer.
Applying principles connected with Articles 860 and 1014 of the Korean Civil Act, the appellate court held that the property already disposed of before judicial confirmation of the additional heirs remained with the purchaser. Those later-confirmed heirs could instead claim the monetary value of their inheritance shares from the heir who had disposed of the property.
It would therefore be incorrect to say this buyer ultimately lost 80% of the property. The published appellate ruling protected the buyer's ownership.
What makes the case instructive is the coexistence of two ideas: property registration itself has no public faith, but other legal rules may protect a buyer in the specific circumstances.
Can due diligence remove every risk?
Title review matters. But I learned that the legal relationships involved could be more complicated than a checklist of documents.
One case cannot represent every transaction, and rights analysis can uncover many risks. Still, a legal relationship that is difficult to detect can have major consequences.
Even a commercial property with a clear title does not guarantee a sound investment. Changes in the neighborhood can make tenants harder to find. During vacancies, rent stops while maintenance costs and interest may continue.
The storefronts I was evaluating offered at most roughly a 4% expected rental yield before tax. Accounting for taxes, upkeep, and potential vacancies made the expected net return look considerably smaller.
The problem of liquidity
Liquidity mattered almost as much as yield.
Selling a storefront requires finding a buyer, negotiating a price, signing a contract, and completing the settlement. A weak market can leave an owner waiting a long time to sell at an acceptable price.
If I suddenly needed KRW 10 million, I could not conveniently sell just that fraction of my shop. A substantial amount of capital would remain tied to one asset.
A well-bought commercial property can certainly be a good investment. For me, however, the expected return did not outweigh the operational demands, legal uncertainty, and limited liquidity.
So I began to ask a different question:
Could I participate in property-generated cash flow without owning and managing the building myself?
That question led me toward REITs and dividend stocks.
