Forging a signature should be convicted. At present, in the equity transfer, the court generally believes that the equity transfer has been completed. In order to ensure the transaction efficiency, the agreement will not be revoked with reference to the bona fide acquisition system, otherwise the agreement will be deemed invalid. Come to think of it carefully, this practice is not right, but actually just to protect fraud. To solve this problem, it is necessary to legislate in the criminal law to convict false signatures, and then the court will decide whether to restore the original equity or compensate for the losses according to the actual situation of equity transfer.
