It all depends upon the facts and circumstances of every case whether it is the wife who was deserted or it was the husband who have actually deserted the wife. Belated filing of FIR does cast doubt on the prosecution story but delay if properly explained is not fatal. But if the wife has deserted the husband wilfully without any reasonable cause and have filed the case for some ulterior motive then, these facts can be brought before the court in the cross examination and can benefit the defence.
what if the wife is not living with husband after marriage and wife is living with her parents and husband and wife has not contacted each other from 2 years. also no FIR is there. then how can they get a divorce. Request you to advise
