Most likely not. There is a Statute on the books that pertains to "living in open (cohabitation....I'm not sure if the word is "adultery" or "fornication"). But it is not largely enforced, if it is ever enforced at all. I see you are writing from Miami. Given the vastness of the legal system in Miami, unless there are other things I do not know, it is extremely unlikely that someone reported for cohabitation will be arrested.
A lot of the things that go on are necessary due process issues, such as determining if the defendant is satisfied with the attorney's services. If the jury has been charged and is in the course of deliberations, it means a lot of downtime for the lawyers.
If the Court has permitted email communication, you may use that as a means of communication. In fact, I often encourage clients in contentious relationships to do just that because the paper trail leaves little room for "he said, she said". Judging from your ex-wife's reaction, she may not trust the email system for just this reason...any way she misspeaks can be presented in court. Don't let her reluctance get in your way. And if she balks in court you can always provide your responses in...
Unless there is some local ordinance of which I am not aware, generally there is no law against it if you are an adult. Moreover, if there is a law against it, I can assure you it is not enforced widely. I see you are writing from Miami. I can't imagine there being any legal prohibition on profanity out of Dade County.
I think that is a very bad idea, for you, your mother, and for your mother's boyfriend. Most likely, if he was convicted he is required to register as a sex offender. And therefore if you stay there, he may end up in more trouble. Even if he can't get in more trouble, I just think that is a bad idea.
You should be fine with an attorney in Virginia, but if you live here, you should ask the Court up there to transfer any probation down here and make sure any sanctions of probation the Courts assign up there are available down here so you do not violate your probation (I am assuming probation will be the disposition) inadvertently. A Florida lawyer may be helpful in making sure the transfer of your probation goes smoothly. Good luck.
It really depends. I can't make a prediction without further information. Do you have prior offenses? How long was your probation? Did you have an appointment with your probation that you missed? You need to talk to a criminal defense attorney as soon as possible to determine your options. Good luck!
