Legally speaking, non-property owners cannot change, mortgage or transfer property rights. However, it is necessary to prevent others from taking the title certificate and pretending to be my identity, and transferring or mortgaging the house without my knowledge.
If you take a copy of the real estate license, there will be no risk, because any unit or individual must show the original when they need the real estate license, and it is useless to rely solely on the copy. It is clear here that some cases or other cases involving real estate licenses have also seen copies in the materials, but these copies are all signed and sealed by the auditors after they are consistent with the original.
Legal basis:
Article 394 of the Civil Code guarantees the performance of debts. If the debtor or a third party mortgages the property to the creditor without transferring the possession of the property, if the debtor fails to perform the due debt or realize the mortgage according to the agreement of the parties, the creditor has the right to be compensated in priority for the property.
The debtor or the third party specified in the preceding paragraph is the mortgagor, the creditor is the mortgagee, and the property that provides guarantee is the mortgaged property.
