It is generally not allowed to make a will for the expected property, because the expected property is only a prediction, which may be profit or loss, and is uncertain. The Inheritance Law of China stipulates that inheritance is the legal personal property left by citizens when they die, and a testator can only make a will on his or her legal personal property before death. Expected earnings, also known as expected earnings, refers to the earnings that can be predicted based on known information if there is no unexpected event. Generally, future asset returns are uncertain, and expectations are predictions that may or may not be realized. Therefore, lawyers suggest that if a will is to be made, a will should be made for the property that the testator can dispose of when making a will. If there is any change after the establishment, a new will can be established to replace the content of the old one.
 The inheritance law of our country stipulates that inheritance is the legal personal property left by citizens when they die, including: citizens' income; Citizens' houses, savings and daily necessities; Citizens' trees, livestock and poultry; Citizens' cultural relics, books and materials, etc.
