Answer :

In the Name of Allāh, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
 
(1) It is well understood that Sharī‘ah gives much importance towards the rights of parents. Allāh Ta‘āla has clearly mentioned the rights of our parents in the Holy Qur`ān, consider the following verse:
وَوَصَّيْنَا الْإِنْسَانَ بِوَالِدَيْهِ حَمَلَتْهُ أُمُّهُ وَهْنًا عَلَى وَهْنٍ وَفِصَالُهُ فِي عَامَيْنِ أَنِ اشْكُرْ لِي وَلِوَالِدَيْكَ إِلَيَّ الْمَصِيرُ 
And We have enjoined upon man [care] for his parents. His mother carried him, [increasing her] in weakness upon weakness, and his weaning is in two years. Be grateful to Me and to your parents; to Me is the [final] destination. [Surah Al-Luqmān, 14]
As such, it is an extremely important aspect of marriage that one learns to establish a fair balance between the rights of one’s parents and the rights of the spouse. A couple will encounter various situations where both must make compromises for the sake of maintaining a blissful marriage.
With regards to question one, we understand the difficult situation of your wife where she holds the responsibility of looking after your household and at the same time her parents due to the circumstances mentioned in the query, however, the only obvious advice that could be given is that your wife must look after her parents as much as possible as well as looking after your household. In order for your wife to carry out such a responsibility, as a husband, it requires effort and support from your side as well so that she may fulfill her responsibilities in a peaceful manner. Furthermore, as a wife, she has the right to make occasional visits to her parents’ home^[1].
(2) As stated above, one must establish a fair balance between the rights of one’s parents and the rights of the spouse. In light of this general principle, along with providing the necessary expenditure of your wife, you must also provide whatever support or help your parents’ require.
(3) A woman is in the care of her father before marriage and in the care of her husband after marriage. If the father is unable to look after her before marriage then other responsible family members are obliged to look after her, such as the brother.
As such, it is necessary that you undertake the responsibility of looking after your sister as much as possible.
