Can an adopted child successfully sue her adoptive parents for a share of an inheritance the parents received from her natural father (upon his death) when the child was 10 years old? The child's natural father was also that of the adoptive father. The child is now 50 years old and only now asking for the inheritance. The land and money were in another country. The family lived in the State of CA. All the other heirs of the natural father (sister, etc) abdicated their shares since the inheritance had little monetary value.
