Appeal for Interim maintenance under HMA Sec 24

I filled divorce petition on cruelty. After skipping various dates and citing multiple pleas, she attended at last and submitted WS and an appeal/petition to receive maintenance pendente lite and litigation cost as per Sec. 24 of HMA. In application she mentioned her occupation as a school teacher but not disclosed her salary, savings, assets etc. Due to her extramarital relation terming as cruelty I left my official accommodation started staying with my aged mother in her residence for last one and half years, which is the ground of my petition. But she is continuing to stay at my official residence. Her school where she teaches is 550m from my official residence. I am paying monthly rental and electricity bill and forgoing a good amount of House Rent Allowance as I am in possession of official accommodation. I have only son who is an adult and employed. There is one apartment is in adjacent district purchased earlier on my own thrift. having the name of both is vacant. I have no house any other house in my name. It is fact that I am drawing six times of her salary bur her salary is sufficient to maintain her livelihood as she availing my official accommodation. What will be grounds of objections from my side to avoid paying interim maintenance and litigation cost. I am ready to handover the apartment which is in joint name if she vacates my official accommodation.
