Designated Investigation Agency | Asset Evaluation of Residential Land History to Detect Risks from Past Land Categories

Block corporate environmental liabilities. Thoroughly evaluate past land use change history and mixed-use land risks, and fully visualize potential underground contamination through residential land transaction sampling.

This document is a practical guide for the management planning departments and legal and financial personnel of companies engaged in M&A, organizational restructuring, and real estate securitization. It aims to uncover environmental liabilities hidden beneath the land owned or acquired by these companies by examining past land registration categories. Even for residential land other than forests and wilderness, a meticulous review of the historical "land category change records" can visualize the contamination risks of specific hazardous substances that could undermine a company's social credibility. In particular, it focuses on the "mixed-use land risk," which is often ambiguous in usage and prone to contamination risks, and explains strict historical verification methods using public registers and chronological aerial photographs. Furthermore, it covers the introduction procedures for "land sale sampling," which enables definitive financial evaluations, and the process for building public evidence through designated investigative agencies. This highly practical guide aims to mitigate critical corporate risks such as hidden defects and damages related to soil contamination that may be discovered after transactions, thereby supporting reliable corporate value assessment and compliance adherence from a technical perspective.
