A practical guide to complementing important matter explanations and eliminating disputes in land transactions! Completely prevent hidden defect risks through historical land investigations and sampling before contracts.

In the field of real estate transactions, the discovery of soil contamination after the handover can escalate into a serious dispute involving not only the seller and buyer but also the brokerage company. Particularly overlooked "hidden defects" can create significant development risks and legal or financial troubles if no prior measures are taken. This explanatory document thoroughly discusses the benefits of introducing "historical land investigations before contracts" to prevent customer disputes in real estate brokerage and enhance the accuracy of important disclosures. By meticulously analyzing the past usage history of the land and public notification documents, the neutral and rigorous designated investigation agency, Geotech, visualizes the invisible underground risks and strongly complements the important disclosures. Furthermore, in cases where there are concerns about contamination, voluntary sampling investigations can be conducted to establish reliable numerical data evidence, facilitating negotiations to include specific defect liability clauses in the sales contract. This is practical know-how to protect the brokerage company's own risk management and social credibility, ensuring safe and smooth land transactions.

Applications/Examples of results

In the real estate brokerage industry, it is widely used as supplementary material for important explanations before contract signing and in the buying and selling practices of land, factory sites, and commercial facilities. It serves as a safety verification method for buyers to detect hidden defects in advance and encourages sellers to adopt it as a risk management tool to avoid claims for damages or long-term legal disputes after the sale. Additionally, it is utilized as objective evidence in formulating specific defect liability clauses based on numerical data and in price burden negotiations, aimed at maintaining trust with clients, preventing customer disputes for brokerage companies, and facilitating smooth transactions.
