Your friend has got grounds to file a divorce case on the grounds of desertion and cruelty provided he continues to reside in his own city because it is this place that his wife deserted him and not the new place and in case of he shifting to new town, he should have informed his wife about this asking her to join him in the marital voyage either through his lawyer's notice or otherwise.  It seems he is trying to escape from his marital obligations by shifting his residence to some other place avoiding his wife to live with him together and if he chooses to do so, he must prove the strong evidential reasons of his allegations namely cruelty by his wife to him.  If he is able to prove that there were no cohabitation between him and his wife for a period of more than two years and that she is not willing for that, he can proceed with a case for divorce against her, ask him to contact a prudent lawyer on the subject and proceed as  per his guidelines.  Advocate Kalaiselvan, Vellore, ph: +919443441062
