This public forum does not give you attorney-client privilege. You and I have not entered into an attorney-client relationship. I am not responsible for your legal rights and this answer is based solely on the information you have provided in your question and as always, I would advise that you arrange for an in person consultation with an attorney from my firm or another Family Law attorney familiar with Florida Family Law who can analyze the specific facts and circumstances of your case more closely to better advise you.
Sure, you can file a motion for contempt (and maybe you should). You can find the form online at www.flcourts.org.
