For the purpose of determining inheritance when there is no Will or other instrument disposing of property (called “intestate succession”) by, through, or from a person, California Probate Code Section 6450 provides that a relationship of parent and child exists in the following circumstances:
(a) The relationship of parent and child exists between a person and the person’s natural parents, regardless of the marital status of the natural parents.
(b) The relationship of parent and child exists between an adopted person and the person’s adopting parent or parents.
California Probate Code Section 6452 says that if a child is born out of wedlock, neither a natural parent nor a relative of that parent inherits from or through the child on the basis of the parent and child relationship between that parent and the child unless both of the following requirements are satisfied:
(a) The parent or a relative of the parent acknowledged the child.
(b) The parent or a relative of the parent contributed to the support or the care of the child.
