Incompatibility between the couple leads to filing of divorce by son. Couple has no issue. Both nearing 40 yrs age. D-I-L and her parents had filed complaints in PS for harassment, cruelty, physical violence, dowry demand etc. because she was prevented from entering house. Where she goes, what she does, when she returns there is no intimation by her. The couple and the in-laws are all medical doctors. The D-I-L requests dept for transfer outside present place of living citing harassment by in laws for dowry etc. Orders of transfer issued but she asks and gets extension to stay saying she has a case filed against her by husband and also that she is a 'destitute'.
