Dear Client, 

According to the Guardian and Ward Act of 1890, the child's welfare is of utmost significance, and courts with competent authority work to strike a balance between the two. Moreover, just because one parent is granted custody of the kids doesn't mean that the other parent is cut off from communication or visitation rights. The courts in India ensure that the child receives the love and care of both parents. The other parent is granted visitation privileges by the court, with the court setting the terms. The Hon'ble Supreme Court and other Indian courts have stated time and time again that the minor's welfare is the only factor taken into account when deciding who gets custody of them, regardless of the claims of the parties to the custody of children. 

A course of unprovoked and abusive behaviour towards one's spouse that results in unbearable humiliation, distress, and misery is referred to as mental cruelty. This behaviour harms the complainant's physical and mental health and makes it impracticable for the complainant to preserve their marital status. The type of cruel treatment, the psychological effects on the spouse, and whether or not it makes the spouse reasonably fear that living with the other spouse would be "harmful" or "injurious" are all important factors to consider when determining whether or not something qualifies as mental cruelty. Therefore, the determination of cruelty is essentially an inferential process that involves considering the characteristics of the behaviour and its impact on the spouse who is lodging the complaint.  The court stated that in handling these kinds of cruelty charges, it is crucial that the court refrain from looking for a universal standard of cruelty because cruelty in one instance might not be cruelty in another. It is necessary to take into account the parties' "economic and social conditions," "culture and human values to which they attach importance," and the type of living to which the parties are accustomed. 

Hope this answer proves beneficial to you.
