Case at a Glance
Our client, a financial institution holding priority beneficiary status under a real estate security trust over a commercial building, found its enforcement rights obstructed when the building's contractor asserted a lien over the property on the basis of unpaid construction fees — while a public auction was already underway. Critically, the contractor held a final court judgment confirming the existence of its construction fee claim, making a direct challenge to the secured debt effectively unavailable. Law Firm Jinheon redirected the legal battle entirely — focusing not on whether the debt existed, but on whether the contractor's possession of the building had been lawfully established. By demonstrating that the possession had been initiated without legal authority after the security trust was put in place, Law Firm Jinheon secured a judgment confirming that no lien existed.
1. Why the Client Came to Law Firm Jinheon
Our client was a financial institution that had extended a loan of several billion KRW to a developer in connection with a commercial building project, securing its position as priority beneficiary under a real estate security trust over the building. When the developer defaulted, a public auction was initiated by the trust company. The contractor that had built the building then intervened — asserting a lien based on unpaid construction fees running to several billion KRW and disrupting the auction process. The building was passed in at auction eight consecutive times as a result.
Making the situation more difficult, the contractor had already obtained a final court judgment in a separate action confirming that the developer owed it several billion KRW in unpaid construction fees. Our client came to Law Firm Jinheon seeking a way through.
2. Law Firm Jinheon's Legal Strategy
The case presented a structural challenge from the outset. With a final judgment confirming the existence of the construction fee claim, directly denying the secured debt was not a viable path. Law Firm Jinheon made a deliberate strategic choice: rather than fighting on the terrain of whether the debt existed, the battle would be fought on a different legal element entirely — whether the contractor's possession of the building had been lawfully established.
First, we precisely identified the timing of the contractor's possession. A property appraisal report prepared immediately before our client's loan was disbursed showed clearly that at that time, the building's exterior bore no signs of any lien claim whatsoever — no banners, no notices, nothing in the rights investigation summary. This directly contradicted the contractor's claim to have been in continuous possession since completion of construction. Law Firm Jinheon used this objective documentary evidence to establish that the contractor's possession could not have begun any earlier than after the loan was disbursed.
Second, we constructed the legal argument that the possession had been initiated unlawfully. By the time the contractor took possession, ownership of the building had already transferred to the trust company under the security trust agreement. The contractor had not obtained the consent of the trust company — as owner — before taking possession. The developer itself had argued in the construction fee proceedings that the contractor was in unlawful occupation. Law Firm Jinheon applied Article 320(2) of the Civil Act with precision: possession initiated through unlawful conduct cannot give rise to a lien. The contractor had commenced possession knowing it had no legal basis to do so.
Third, we filed a pre-emptive action for confirmation of non-existence of lien, strategically placing the burden of proving the lien's elements on the contractor. In a negative confirmation action under Korean law, it is the party asserting the lien — not the party denying it — who must prove possession and the existence of the secured claim.
3. The Outcome — Non-Existence of Lien Confirmed, Full Victory
The court accepted Law Firm Jinheon's arguments and delivered a judgment confirming that the contractor's lien did not exist. While the court recognised that the construction fee claim itself was established by the prior final judgment, it found that the contractor's possession had been commenced without lawful authority after the loan was disbursed and after the security trust was established — that the contractor was aware at the time that it had no basis to possess the property — and that this possession therefore constituted unlawful conduct within the meaning of Article 320(2), precluding the formation of a lien. All litigation costs were ordered to be borne by the defendant.
A full victory, achieved despite the existence of a confirmed judicial finding of the underlying debt.
4. Why This Case Matters — And Why Choose Law Firm Jinheon
This case was not a straightforward lien dispute. The other side held a final court judgment. The question was not whether there was a debt — there was — but whether the specific legal conditions for a lien, taken as a whole, had been satisfied. Law Firm Jinheon identified that the battlefield should be shifted to the element of lawful possession, and then built the case on that ground with precision.
Lien disputes arising within a real estate security trust structure involve a distinct and layered body of law: the legal effect of possession after a trust is established, the significance of the trustee's consent, the legal standing of the priority beneficiary. These are not questions that can be answered without genuine command of real estate, finance, and trust law together. Law Firm Jinheon brought that specialist knowledge directly to bear — finding the path to a complete victory where a conventional approach would have run out of road.
A final judgment confirming a construction fee claim does not necessarily mean a lien exists. If a lien claim is obstructing a public auction or enforcement process involving a property held under a security trust, Law Firm Jinheon can find the way through.
