Hello! The marriage law of our country stipulates that only stepchildren who form a custody relationship with the decedent have the right to inherit. If there is no custody relationship, they cannot inherit the inheritance. The woman or her adult son cannot take charge of the property of the minor daughter of the man. Since she has a guardian and is her mother, her mother should act as his agent in civil activities. Reference content: online consultation of the legal profession on the waiver of inheritance right The waiver of inheritance right refers to the intention of the heir to refuse to accept the heir's estate. According to the Inheritance Law, the inheritor can abandon the right of inheritance, which means abandoning other rights related to the right of inheritance.
 1、 Abandonment of the right of inheritance does not result in subrogation. If the right of inheritance is expressly waived before death, the person giving up the right of inheritance dies before the decedent, and when the decedent dies, the heir's children lose the right of subrogation. Although the death of the successor before the decedent is the only condition for the generation of subrogation, before the death of the successor, the right to inheritance has been expressly waived, that is, the right to enjoy the inheritance of the decedent free of charge. The waiver of this right indicates that the successor has no right to inheritance, that is, a child without an heir, Of course, there will be no question of succession by subrogation. Therefore, if you give up the right of inheritance, there will be no question of succession by subrogation.
