Wife doesn't allow Husband to earn but demands maintenance

Couple have been married for 10 years. Both are qualified but wife keeps her money and gets money from husband for all expenses. Husband unfortunately lost his life savings due to bad investment decisions. Wife decided to separate as in her words, he's broke. Husband still has a property that wife demanded along with a hefty one time alimony. When he refused to part with it or borrow money for her alimony, she threatened to sue him. She filed FIRs and suits under 498a and several other sections. She has filed approx. 9 different cases against him with the most vile allegations. She publicized all the cases. She then sent all FIRs, press clippings and other material to his workplace and he was terminated but they refuse to share reason. She has since done it repeatedly wherever he tries to get a job. Recently, a well meaning HR employee who's also a friend showed him the incriminating docket she sent to this company. It has a covering letter addressed to the company officials and clearly signed off by her. Husband has been able to get a copy of it. Armed with this evidence, how can he convince Family Court Judge that he has no income as he's unable to get a job due her actions? She has filed for interim maintenance, maintenance, etc. because as per her she's unable to work due to ill health from illnesses.
