1. Testamentary trust refers to the collection and settlement of creditor's rights and debts related to the execution of the will, the delivery of testamentary items, the disposal and division of the estate after the death of the testator according to the will or the ruling of the relevant court. The establishment of testamentary execution trust is mostly due to the testator's more property, the complicated relationship between estate division and disposal, and the lack of reliable executors.
2. Managing the estate trust is a trust business entrusted by the testator or the court to manage the estate within a certain period of time. This kind of business can be divided into two situations: "undetermined inheritance" and "fixed inheritance".
