Excessive Litigation

I am constantly getting Motions to Show Cause that are bogus and fictitious. These are causing me stress and medical issues (I am epilecptic). What can I do to stop her from filing these?

Also, the last one was a Motion and Affidavit For Contempt. Do I need to file a response to this prior to court to say why it is false or bring my evidence to court that it is?

You need not file a response, but must appear in court to defend the motion. If your ex is truly filing bogus motions you may file a motion under Rule 11 for sanctions.
