Husband transfers properties to brother's name to deny maintenance

Since 1.5 yr I am staying away from my husband house and staying with my parents.I had filed domestic violence and maintenance under section 125cr p.c n 23(2), sec12 in Feb 2016. He has submitted his account details in the court in April 2018.This case is at family court saket.he is given the details of the account which does not have balance and was a normal saving account which he was hardly using it. however I am sure he was other accounts too and he is a income tax payer also. Through sources i have come to know that he has made all this assets on his brother name so that he can play safe and does not want to show anything in the court too. My questions are as follows -: 1) I have his pan card and adhaar card number.How can I find out how many accounts he has presently in the indian bank? 2)How much income tax is he paying ? 3) Details of his assets on his name ? 4) He has run to Australia in 2017 now how can I challenge him in court.
