Mr. Cook is correct. You have posted this question in the criminal law domestic violence PRACTICE AREA. Pose this question in the FAMILY LAW practice area and you will receive more responses from family law practitioners. Schedule several free consultations with local family law attorneys and than pick the one you trust, like and can afford. Good Luck. Hope this helped?
Does he ever make threats to harm you or your children? Or does he act in a threatening way? If so, call 911 and report it as a crime. His actions could violate Penal Code 422 (verbal threat of harm) or P.C. 415 (disturbing the peace) at the very least. If he touches you in anger, it's domestic violence. Or, if his actions do not rise to that level, seek a Restraining Order as the other attorneys have suggested. Good luck!
