Trust is one of the important contributions of common law to the world legal system, which originated from the relationship between land use and income in medieval England, that is, the landowner gave the land to others for possession and use, but agreed that the land income would belong to the original landowner. After the dispute arose, because the ordinary courts failed to protect the rights of the beneficiaries according to the theory of ownership transfer, the equity court of King Henry III of England fairly protected the rights and interests of the parties according to the principle of fairness and justice. By the16th century, the trust system was finally formed. Therefore, the so-called trust means that the property owner gives the property to the trustee for possession, use and disposal based on the trust. However, it is a system that agrees to give the proceeds to a specific person or achieve a specific purpose. Based on this, people can use wills or contracts to set up trusts for various legal purposes in civil, commercial or public welfare fields. It is not regarded as a unique legal structure with deep social functions. Trust legal relationship has four elements. One is the trustee, that is, the person who delivers the property to others for the purpose of not breaking the law; Second, the trustee of the trust, that is, the person who accepts the entrustment of others and occupies and manages the property of others for his own benefit; The third is the beneficiary of the trust, that is, the person who does not own the property under management but has the right to obtain the property income; The fourth is the trust property, that is, the trust object. Therefore, trust can be understood as that the trustor has handed over the trust property to the trustee. Although the trustee has obtained the ownership, he has no right to control others for his own benefit or according to his own will, and only controls the obligations of others according to the wishes of the principal for the benefit of the principal or other persons designated by the principal.
