Under the Hindu Marriage Act, 1955, the following are valid grounds for divorce under Section 13(1): • Desertion for at least two years • Conversion to another religion • Cruelty, adultery, mental disorder, etc. However, “Irretrievable breakdown of marriage” is not explicitly mentioned in the Act as a ground, though the Supreme Court can grant divorce on this ground under Article 142 of the Constitution. Legislative amendments to include this are still pending.
