After the death of husband and wife, why do you need to sign the property to your spouse?

First of all, it depends on whether brothers and sisters have rights to the house. Article 122 of the Civil Code of People's Republic of China (PRC) stipulates that an inheritance is the personal legal property left by a natural person when he dies. An inheritance that cannot be inherited according to the law or the nature of the inheritance shall not be inherited. If the property is the personal legal property of the decedent, it can be inherited as an inheritance. Secondly, Article 123 of the Civil Code stipulates that: after the beginning of inheritance, it shall be handled in accordance with legal inheritance; If there is a will, it shall be inherited or bequeathed according to the will; If there is a legacy support agreement, it shall be handled in accordance with the agreement. If the decedent leaves a corresponding will and clarifies the issue of property inheritance, then it needs to be inherited according to a valid will. If the inheritance rights of his brothers and sisters are excluded in the will, then the brothers and sisters have no right to inherit the house. In the case of leaving a will, there is no need for others to cooperate in inheritance.

Secondly, Article 1 127 of the Civil Code stipulates that the inheritance shall be in the following order: (1) The first order: spouse, children and parents; (2) The second order: brothers and sisters, grandparents and grandparents. After the inheritance begins, the successor in the first order inherits, and the successor in the second order does not inherit; If there is no successor in the first order, it is inherited by the successor in the second order. The children mentioned in this part include children born in wedlock, children born out of wedlock, adopted children and stepchildren with dependency. The parents mentioned in this part include biological parents, adoptive parents and step-parents with dependent relationship. Brothers and sisters referred to in this part include brothers and sisters of the same parents, half-brothers, adopted brothers and sisters, and stepbrothers and sisters with dependent relationship. It can be seen that after the beginning of inheritance, if there is a first heir, the second heir will not inherit. Therefore, if the decedent still has a spouse, parents or children, brothers and sisters will not enjoy the right of inheritance. If the decedent does not leave a valid will, he needs the cooperation of others when inheriting the property, because it is necessary to check whether the decedent's parents are alive and whether there are inheritance problems.
