A Hindu wife has no right in the property of her in laws (except for maintenace). Off course she is one of the heirs of her husband property. Similarly, husband is a heir of her property (except the property inherited by her from her father).
As far as property rights go, a women has equal property rights just like man, as a heir of their father property. Further, a women has been made a coparcener in the joint hindu family of her father. She remains so, even after her marriage in a different joint hindu family.
Thus a women has equal opportunity to inherit property.
