This is not possible.
After the real estate certificate is lost, others cannot use it for mortgage loans. Because the real estate mortgage requires the owner with the real estate certificate to bring the ID card and the real estate certificate before it can be applied for, and the mortgage cannot be applied for only the real estate certificate. Basically, anyone who does not hold the real estate certificate cannot handle any affairs.
If the real estate certificate is lost, it can be reissued, but you need to prepare relevant application materials and follow certain procedures. The procedures required for re-issuing a real estate certificate include application for spare parts, filing and filing, declaration in the newspaper, survey and registration, registration review and approval, and certificate repair and issuance.
