Strongly supplementing important matter explanations to prevent contract cancellations! Practical historical investigations to thoroughly manage risks and prevent customer troubles in real estate brokerage companies.

In the practice of real estate sales contracts, the discovery of soil contamination after the transfer of property poses a significant business risk, leading to long-term legal battles over damage claims and contract cancellations. Particularly, it is extremely difficult to detect "hidden defects" that even the seller may not be aware of, solely through regular land inspections. This explanatory document provides a detailed practical guide on "historical land investigations before contracts" to maximize the safety of transactions and thoroughly prevent customer disputes after the transfer. By rigorously examining the past usage history of the land and public notification documents, GeoTech, a designated investigation agency under the Soil Contamination Countermeasures Act, visualizes invisible underground risks in advance and strongly supplements the reliability of important matter explanations. Furthermore, it covers the establishment of numerical data evidence through voluntary sampling investigations in cases of contamination concerns, as well as how to incorporate defect liability clauses into sales contracts. This practical guide aims to strengthen the risk management system of brokerage companies and promote smooth land transactions while maintaining social credibility.
