Inheritance Of Daughter-In-Law
Her primary responsibility is towards her husband and children. The care of a father falls on his son, not on his daughter-in-law. This question likely arises from the joint family system prevalent in some Eastern cultures, but this is not a universal family structure. A husband and wife are meant to live together independently. No ethical or religious law obligates a daughter-in-law to care for her father-in-law or mother-in-law.
