Nev. Rev. Stat. § 127.160
Upon the entry of an order of adoption, the child shall become the legal child of the persons adopting the child, and they shall become the child's legal parents with all the rights and duties between them of natural parents and legitimate child. By virtue of such adoption the child shall inherit from his or her adoptive parents or their relatives the same as though the child were the legitimate child of such parents, and in case of the death of the child intestate the adoptive parents and their relatives shall inherit the child's estate as if they had been the child's natural parents and relatives in fact. After a decree of adoption is entered, any parent who has signed a relinquishment or given consent to terminate his or her parental rights is relieved of all parental responsibilities for the adopted child and shall not exercise or have any rights over the adopted child or the property of the adopted child. The child does not owe a parent whose parental rights have been terminated any legal duty and may not inherit from a parent whose parental rights have been terminated or his or her kindred. Notwithstanding any other provisions to the contrary in this section, the adoption of a child does not in any way change the status of the relationship between the child and any legal parent who is a petitioner and whose parental rights have not been terminated.
