It refers to a financing method in which the borrower pledges the eligible movable property to the bank, and the bank, the borrower and the third party sign a tripartite agreement, entrusting the third party to conduct daily supervision of the movable property during the pledge period, and ensuring the safety of the pledged property, and the bank provides the borrower with credit support in local and foreign currencies such as loans, discounts and bill acceptance. Third parties refer to asset management companies, professional logistics companies and professional warehousing companies. , established in accordance with the law, with the qualification and ability to supervise the pledge of movable property. Relevant legal knowledge: according to the difference of pledge, pledge can be divided into chattel pledge and right pledge, while China's security law only stipulates chattel pledge and right pledge. Property is called pledge, the person who provides the property is called pledger, and the person who enjoys the pledge is called pledgee. A written contract is required for pledge guarantee, and the pledge contract will take effect immediately (different from the previous view that the pledge contract is a practice contract, the new view holds that the pledge contract should also be a promise contract), and the content of the pledge contract is basically the same as that of the mortgage contract. Pledge is divided into chattel pledge and right pledge. Chattel pledge refers to the pledge of movable things that do not damage its effectiveness; Pledge of rights refers to pledge with transferable rights as the subject matter. The pledgee of chattel pledge shall bear civil liability if the pledged property is lost or damaged due to improper custody. Where the pledged property may be lost or damaged, the pledgor may require the pledgee to deposit the pledged property or pay off debts in advance to return the pledged property, and the pledgee may require the pledgor to provide corresponding guarantees. If the pledgee fails to provide the pledged property, the pledgee may auction or sell the pledged property for priority compensation or deposit it with a third party agreed with the pledger. If the redemption date or delivery date indicated on various bills is earlier than the debt performance period, the pledgee may redeem or deliver the goods before the debt performance period expires, and agree with the pledgor that the cashed price or the extracted goods will be used to pay off the debt in advance or deposit with a third party agreed with the pledgor. Where the property rights in stocks or trademarks, patents or copyrights that can be transferred according to law are pledged, the pledgor and the pledgor shall, after signing a written contract, register the pledge with the securities registration agency or its administrative department, and the pledge contract shall take effect from the date of registration. Because there is no specific law, I will explain it roughly. Legally speaking, the duration refers to the term of validity of a contract or right, during which it is legally valid or agreed to be valid. An uninformed third party is relative to an informed third party. For example, knowing a third party is knowing that the purchased goods or rights are defective in law, which will damage the rights and interests of the relevant people. An uninformed third party has committed the same legal act without knowing it at all. The so-called uninformed third party is hard to blame. In law, the uninformed third party will not be punished, while the informed third party will bear joint and several liability for compensation and so on.
