Optimize the seller's disclosure obligations and alleviate the buyer's concerns! Enhance the safety of land transactions through accurate due diligence based on historical land surveys before the contract.

In real estate transactions, the seller's duty to disclose and issues related to the history of land use carry the risk of developing into significant legal disputes after the contract is signed. Particularly, unseen soil contamination underground is the greatest concern for buyers and a major factor that hinders safe transactions. This explanatory document details the effectiveness of "pre-contract historical investigations" that real estate brokerage companies can use to quickly alleviate customer anxieties and facilitate smooth land transactions through honest information disclosure. GeoTech, a specialized organization designated by the government, prepares objective evaluation reports that significantly enhance the reliability of important matter explanations by analyzing and scrutinizing past public notification documents and detailed land histories from multiple perspectives. Furthermore, it covers methods for building scientific evidence through voluntary sampling investigations when contamination risks arise, as well as how to incorporate defect warranty clauses into contracts. This practical guide emphasizes thorough due diligence as a brokerage company, ensuring reliable contract practices while protecting the asset values of both parties.
