Soil contamination survey

To prevent defects liability troubles and court disputes after land transactions, we propose a buyer-led historical land investigation and sampling as a preventive measure before the contract.

This is a pre-contractual self-investigation solution designed to thoroughly protect the buyer's rights and assets from "hidden defects such as soil contamination," which is the most likely source of disputes in land sale contracts. If contamination is discovered after the transaction is completed, there is a high risk of escalating into a protracted legal battle over damages and contract termination, which can significantly impact a company's management. Our service conducts a "buyer-side historical investigation" during the due diligence period before contract signing to objectively verify the authenticity of the seller's information disclosure. Furthermore, if there are suspicions of contamination, we proceed to a "voluntary Phase 2 sampling investigation" that has legal evidentiary value, establishing solid numerical evidence based on official analysis. Based on this scientific data, we clearly define the burden-sharing of remediation costs and special clauses regarding defect liability within the sales contract, completely eliminating the development risk of the buyer incurring unexpected cleanup costs. This is a strategic solution to maximize the safety of land transactions from a legal and contractual perspective.

basic information

We conduct rigorous public specification investigations and analyses that demonstrate complete evidential capacity in contract negotiations and legal disputes. In historical investigations, we meticulously verify and report on various evidence that proves public agency archive materials, past notification documents, and land history. In sampling, we strictly adhere to the sampling and measurement technical standards established by the Ministry of the Environment, conducting precise quantitative analyses of specific hazardous substances by registered analytical institutions in the measurement certification business. All data is submitted as reports with tamper-proof traceability, designed to be used directly as attached documents to contracts.

Applications/Examples of results

The legal representatives on the buyer's side, contract lawyers, and asset managers in real estate transactions will introduce this as the final due diligence before signing. It is used to identify the scope of warranty liability that should be included in the contract for the acquisition of land-attached companies and business properties, with the aim of mitigating future damage compensation risks. It serves as legal backing for price negotiations with the seller, drafting of special clauses, and as definitive documentation to obtain compliance approval from the internal investment committee.
