Not all parents are married. Regardless, the same rules under "Child Custody" and "Parenting Plan" apply. The same criteria will be evaluated by the Florida Divorce court in a paternity action when establishing custody and visitation ("timesharing") and the parties' Parenting Plan.
If a person who lives with you or lived with you commits an act of domestic violence, then you may go to the Clerk of Court to fill in the paperwork. Your Petition (for Protection Against Domestic Violence) would then go upstairs to the Court for a review. The Florida Divorce court may then issue a "temporary" injunction requiring that the offending person stay 500 feet from you, your home, your work, etc. Within 15 days, a "Return Hearing" will be held at which time you will be afforded the opportunity to speak and for the offending party (Respondent) to answer to the allegations. The Florida Divorce and Family law court may then issue an injunction (what is commonly referred to as a "restraining order"). The Injunction is usually not indefinite.
