Rigthly opined by Ranee and Dr. J.C. Vashista.
to add,probably you are misguided.Your lawyer needs to counter stating that there is no need for interim maintenance by virtue of her being well educated and currently earning and is from a stronger financial backgound.Your lawyer can/should take out citations in this regard and need to defend the plea for interim maintenance strongly.He should also forth all your labilities.
Property - Does she know about this? Even if the answer is affirmative she does not have a right over your property.Her plea for seperate residence can also be negated by using her HRA details.
Your lawyer should defend the case that the lady is not entitled for maintenance,but,at the most if you do not have a child(ren) your maintenance liability to your wife should drastically come down.
