At present, property titles are often paper-based, creating opportunities for errors and fraud. Title professionals find defects in 25% of all titles during the transaction process, according to the American Land Title Association.
Any identified defect makes it illegal to transfer a property title to a buyer until it is rectified. This means property owners often incur high legal fees to ensure authenticity and accuracy of their property titles.
Moreover, title fraud poses a risk to homeowners worldwide. US losses associated with title fraud reportedly averaged around $103,000 per case in 2015, compelling many property buyers to purchase title insurance.
These title management issues could potentially be mitigated by using blockchain technology to build immutable digital records of land titles and using blockchain for transparent transactions. This approach could simplify property title management, making it more transparent and helping to reduce the risk of title fraud and the need for additional insurance.
