domestic violence

This is my first time filing taxes. I've been separated from abusive husband for 2 years. I know that he owns a house that he intentionally bought with gift money from his father so that it is not considered marital property. I want to file but I don't know what he filed. I don't know if he itemized or did standard deduction. I also don't know if he claimed homeowner property tax exemption, and I can't find out. What should I do? Can I file an injured spouse form or something?
