1. How is not having sexual relationship with wife since first day of marriage till 6 years treated in court? We both were not interest in each other.
The essentials of marriage include sexual intercourse between the couple. In the absence of this conjugal relationship the marriage is void. In the normal circumstances, the marriage is solemnised for procreation and this will not be possible only when either of them is impotent or affected by infertile status of health,but tat is an exemption.
In your case, you have been keeping quite for all these six years without the conjugal relationship between you two that too without any complaint from your side about this lacuna. What prevented you from not initiating any action either legally or otherwise to solve this problem? You cannot claim yourself to be magnanimous on this issue or had been observing patience because everything has a limit. You have wasted your six potential years.
The court has got nothing to with this but it is you who has to please befor court the fact and pray for divorce for non-consummation of marriage and all the continuous efforts to patch up the difference for creating a situation conducive for the issue has irretrievably failed. You should convince the court the reasons for not approaching the court earlier or justify for approaching the court very late with this subsisting strong ground.
2. I am job less since one year now and do not have big bank balance. If I proceed through court, generally what compensation would court as me to pay to her?
court will not ask you to pay her compensation. It will be she who will move her claim for maintenance or alimony based on her version about your economic status. You can defend by presenting your actual status and affordability.
We took one lakh as dowry at the time of marriage and they gave 6 lakhs worth gold to her daughter. Even we gave 2 lakhs worth gold to my wife. Will this create any dowry problem? Can we demand our 2 lakhs gold back?
Giving and accepting dowry is prohibited in law and it is an offence. If this is the status, you may have to settle the issues amicably.
