"If the parties agree to prohibit or restrict the transfer of the mortgaged property but fail to register, the mortgagor transfers the mortgaged property in violation of the agreement, and the mortgagee requests to confirm that the transfer contract is invalid, the people's court will not support it;

If the mortgaged property has been delivered or registered, the people's court will not support the mortgagee's request to confirm that the transfer does not have the effect of real right, unless the mortgagee has evidence to prove that the transferee knows it; If the mortgagee requests the mortgagor to bear the liability for breach of contract, the people's court shall support it according to law.
