Mortgage trust is a kind of trust in which the client sets the collateral as trust property for the purpose of obtaining a certain service. Customers mortgage their bills, stocks, bonds and other movable or immovable property to trust institutions in order to obtain loans and credit guarantees from trust institutions. Such as trust mortgage loans, secured corporate bond trusts and other trust businesses guaranteed by trust institutions on the condition of mortgage, all belong to mortgage trusts. Before the client pays off the debt, the property right of the mortgaged property belongs to the trust institution. If the debt cannot be paid off on time, the trust institution has the right to dispose of the mortgaged property and pay it off on its behalf.
