How to file perjury charges against a petitioner? Someone that is lying about the allegations filed?
Many petitions are signed under oath. If the petition was signed under oath and there is clear proof that the allegations were false, you can contact your local State Attorney's Office and discuss the matter with them. Mind you, the State is usually not interested in getting involved with civil domestic matters. They typically will only do so in cases where the proof that the allegations are false is absolute. Good luck.
