Wife has changed her name and while the divorce case is still going on, she is living with someone else. Husband knows the fact but is unable to prove it. She made a pan card by different name and basis of that made different documents.
Now she has two totally different names with different surnames. The name which she is using is said to be the wife of that another guy and the husband is not able to prove that in court. Wife is living with other guy and his family, while the house in which wife is living is by the name of the parents of the other guy. They have made the rent agreement by the name of wife and according to that the wife is living there as a tenant.
They also made a setting in which wife is working in a firm of the other guy, so when they travel it is a business trip. Also they make bookings by that other name of wife, so that bills are not getting accepted as it has different name and also it is a business trip.
There is nothing else to prove as they living together as land lord and tenant. How to prove this?
