Will my wife is entitled to take her share in this flat ?
If yes then Is there any alternative to save this house from her ?
Since the property has been registered on your name alone, you will be the absolute owner with marketable title. Your wife cannot claim any share in the property during your lifetime.
2. Secondly there is no husband wife relationship since our marriage which happened on 11 Dec, 2013. So on this ground can my case will be stronger ?
This can be deemed to be desertion or non-cohabitation for a period over two years, a strong ground for divorce on the grounds of desertion and mental cruelty.
3. She is working and we dont have any kids so how much and till when I need to pay maintenance to her.
My salary take home/month : 88K
Her salary take home/month : 28K
If she is employed and drawing a handsome salary to sustain herself, especially in the absence of any children out of your wedlock, you may repudiate her claim for maintenance, if she files or claims any.
