In the case of Sirajmohmedkhan Janmohamadkhan v. Haizunnisa Yasinkhan & Anr. reported in (1981) 4 SCC 250, this Court stated that the concept of legal cruelty changes according to the changes and advancement of social concept and standards of living. With the advancement of our social conceptions, this feature has obtained legislative recognition, that a second marriage is a sufficient ground for separate residence and maintenance. Moreover, to establish legal cruelty, it is not necessary that physical violence should be used. Continuous ill-treatment, cessation of marital intercourse, studied neglect, indifference on the part of the husband, and an assertion on the part of the husband that the wife is unchaste are all factors which lead to mental or legal cruelty.
