What is the next step ?

My wife filled a complaint in women cell for taking dowry and domastic voilence. I received a notice from women cell. I attend the frist meeting of women cell but nothing will happen. My wife filled a false complaint that her father hasbeen spent rs. 30 lakhs including dowry in the marriage but true is this- her father didnt spend any single rupees in marriage. All the expenses of marriage willbe paid by us. Now i want to know that what should we do to protect our family from false complaint ? What is the next stage after complete all the meetings in women cell if no result will appear in the pend in the marriage ? Her father monthly income is rs.15000/- and Rs.30 lakhs are spending in marriage than what is the income source ? if he fail to provide the income proof than what happen ? Have any other valuable suggestion from your side to protect the family from false complaint. Warms Regards
