Legal analysis: the mortgage has been registered and can be exercised after arriving at the location of the property. If the mortgage is not registered and has no publicity power through litigation, you can negotiate with the mortgagor to pay off the creditor's rights in advance or withdraw the proceeds from the sale of the property. If the mortgaged property has been sold to a third party, it can no longer be investigated for exercising the mortgage right.

Legal basis: Civil Code of People's Republic of China (PRC).
