Legal Question in Family Law in California

No, not exactly.

Adoption under California law creates a parent-child relationship between the child and his or her adoptive parents. (Prob. Code, 6450 subd. (b).)

For intestate succession purposes, adoption also severs the parent-child relationship between the adopted child and a natural parent unless:

(1) The natural parent and the adopted person lived together at any time as parent and child, or the natural parent was married to or cohabiting with the other natural parent at the time the person was conceived and died before the person�s birth.

(2) The adoption was by the spouse of either of the natural parents or after the death of either of the natural parents

(b)Neither a natural parent nor a relative of a natural parent, except for a wholeblood brother or sister of the adopted person or the issue of that brother or sister, inherits from or through the adopted person on the basis of a parent and child relationship between the adopted person and the natural parent that satisfies the requirements of paragraphs (1) and (2) of subdivision (a), unless the adoption is by the spouse or surviving spouse of that parent.

(c)For the purpose of this section, a prior adoptive parent and child relationship is treated as a natural parent and child relationship. (Prob. Code, � 6451 subd. (a).)

Intestate means they died without a will and no other legal disposition governs the property. If they left a will, they can will the property to whomever they want.
