I'm Lucy, and I'd be happy to answer your questions today. I'm sorry to hear about your situation.
In Florida, a judge can enter a restraining order if he finds that you're in immediate danger of becoming a victim of domestic violence. That includes threats to you and threats of kidnapping your child. As soon as you go to court and file the request, you can go in front of the judge and ask for an immediate order. That means your ex can be served with a temporary order AND the notice of the suit at the same time, which gives you added protection.
You're allowed to file at the local circuit courthouse in your county or where he lives. Call before you go in, but they should have forms to help you. If you're planning to move and don't want him to know where you're living, then filing in his county is one way to avoid him knowing which county you're living in. This site has more information for you:
After the child is born, you can file immediately for full custody, plus child support, and that will stop him from taking the child away. Filing for custody will not give him a right to contact you when there's an order in place.
