Harassment case against brother-in-law how to safeguard myself

This is regarding divorce case between my brother-in-law (wife's brother) and his wife. After 22 months of leaving home, the girl's family filed a FIR in Haryana (ancestral home) under sections 406/498 for harassment. The names of my brother-in-law, father-in-law and mother-in-law was mentioned in FIR. Subsequently, the boy was arrested and granted bail after 5 days. Now after, 10 months of first case (FIR), the girl's family have filed another case under section 12: Protection of Protection of Women from Domestic Violence Act. In this case, she has alleged that her in-laws used to harass her and after going away from their home, she has to bear high financial expense for herself. In essence, she has asked for regular maintenance. What has changed for me is that my name has been added in the list of respondents. There is just one paragraph for me that I used to visit my in-laws frequently and instigated them to harass their son's wife. What should be future course of action for me.
