“I found out today that her boyfriend has been living there for a few months now and I was never told.” That sentence, posted by a Florida dad on a legal Q&A board, could have been written by any of the men who walk into our office every week. The details change, but the gut punch is pretty much the same.
What’s worse is that usually it doesn’t come from her. It’s from your kid, or from a school form, or from a neighbor. Now there’s a man you’ve never met sleeping in the same house as your children, and when you bring it up, she blows it off and says you’re trying to control her dating life. You’re not (at least you shouldn’t be). You’re trying to protect your kids. The problem is, the law in Florida draws a line between those two things, and you need to know exactly where it is before you do anything else.
I can’t tell you how to feel. And to be honest, that’s not what the law cares about. What the law in Florida lets you do, what it doesn’t, and where to put your energy is what actually counts.
Before you do anything else: Where does your situation actually stand?
Check every box that applies. Be honest. The point isn’t to make your case look stronger than it is. The point is to figure out where to put your energy.
Section A: The things Florida courts actually act on
He has been arrested for or convicted of a violent crime.
He is a registered sex offender, in Florida or any other state.
He has a documented history of domestic violence against your ex, a previous partner, or anyone else.
He has been arrested for or charged with any offense involving a child.
You or your child have witnessed drug or alcohol abuse during your ex’s parenting time.
Your child has told you he hit, grabbed, shoved, or physically disciplined them.
Your child has told you he yelled at them in a way that frightened them.
Your child has come home with unexplained bruises, marks, or injuries since he’s been in the picture.
Your child has said they don’t feel safe at mom’s house, and named him as the reason.
He is living in the home full-time while your child is present.
Section B: The things that feel wrong but courts usually won’t touch
You found out about him from your kid, not from your ex.
He was introduced to the children within the first few months of the relationship.
He attends school events, doctor’s appointments, or parent-teacher conferences.
He has been listed on school forms, medical paperwork, or as an emergency contact without your consent.
He handles drop-offs or pickups at custody exchanges.
He has tried to discipline your kids or override your parenting decisions.
Your ex has referred to him as a “father figure,” “stepdad,” or “dad” to the children.
Your child calls him “dad” or a similar name.
He moved into the home faster than felt reasonable to you.
You find him personally rude, disrespectful, or dismissive toward you at exchanges.
Section C: Where you stand on the record
You have written down specific incidents with dates.
You have saved your child’s exact words, in quotes, in their own language.
You have photos, school forms, texts, or third-party records that back up what you’ve written.
What your answers mean
If you checked anything in Section A: This is the part Florida courts actually act on. Stop scrolling, finish this post, and start documenting today. Then call an attorney. Don’t sit on it.
If you only checked boxes in Section B: Almost everything you checked is real and painful, and almost none of it will get a judge to step in on its own. Read the next two sections carefully. Your energy is better spent on your parenting plan than on a modification petition you’re going to lose.
If Section C is mostly empty: Whatever else you checked doesn’t exist yet, as far as the court is concerned. Start the record today. The documentation template at the bottom of this post is how.
What the Law Actually Says in Florida
Here’s the hard part first. Under Florida Statute § 61.13, each parent generally controls their own time-sharing. During her parenting time, your ex decides who is around the kids, including partners, babysitters, and family. Unless your parenting plan specifically says otherwise, she does not have to ask you, tell you, or get your approval.
Florida courts use a best-interests-of-the-child standard, and one of the factors they weigh is “moral fitness.” That phrase sounds like it gives you more leverage than it actually does. Under Maradie v. Maradie, 680 So.2d 538 (Fla. 1st DCA 1996), a parent’s conduct only matters if it directly and adversely affects the child’s welfare. The mere possibility of harm is not enough. A judge is not going to restrict her time-sharing because her boyfriend is rude, unemployed, or moved in faster than you’d like.
It’s also worth knowing the broader backdrop. HB 1301, signed in June 2023 and codified into § 61.13, created a rebuttable presumption that equal time-sharing is in the child’s best interest. Florida courts now start from the position that both parents should have meaningful, roughly equal time with the kids. Rebutting that presumption takes real evidence, not discomfort.
What the Court Will and Won’t Care About
It helps to separate what feels wrong from what a judge will actually act on. Most of what makes you furious about this situation falls into the first bucket.
A Florida judge generally will not care that he was introduced too soon, that you weren’t told, that he’s annoying at exchanges, that he does pickups, or that he’s “acting like a dad” when he’s not one. Those things are real and they matter to you. They are not, on their own, grounds for the court to step in.
What a judge will care about is concrete and documented risk to your child. A criminal history involving violence, child abuse, or sex offenses. An active domestic violence record. Substance abuse around the kids. A registered sex offender living in the home, which can jeopardize the other parent’s custody entirely. Each of these ties back to the same statutory threshold: direct, demonstrable harm or risk of harm to the child’s welfare. If what you’re worried about clears that bar, you have something to work with. If it doesn’t, the worst thing you can do is file anyway.
What You Can Do Right Now
Start with your parenting plan. Pull it up and read it cover to cover. Some plans include a morality clause or a cohabitation provision that restricts overnight guests during parenting time, requires advance notice of new partners, or sets an introduction timeline. If yours has one and she’s violating it, that’s a real enforcement issue and you should talk to an attorney about your options.
If your plan is silent, morality clauses in Florida can only be added by agreement. A judge won’t impose one on request, and whatever restriction you ask for applies to you too. That cuts both ways, and it’s worth thinking about before you push for it.
Modification is a higher bar. To change the parenting plan, you generally have to show a substantial, material, and unanticipated change in circumstances, and that the change you’re asking for is in the child’s best interest. A new boyfriend, by himself, almost never clears that bar. A new boyfriend with a documented criminal history, an active DV case, or evidence of substance abuse around your kids is a different conversation.
If you believe your child is being harmed or is in immediate danger, you can report it to the Florida Abuse Hotline at 1-800-962-2873. That is a serious step with serious consequences, and it should be based on something real, not on anger. And whatever you do, do not withhold the kids on your own. Florida courts take unilateral denial of time-sharing extremely seriously, and doing it can flip the entire case against you overnight.
None of That Matters If You Don’t Document It
Everything above collapses into one practical point. Nothing you say in court carries any weight unless you can show it happened, when it happened, and how you know. A dad who walks in with a neat, dated record of specific incidents is in a different universe than a dad who walks in angry with a story. Start the record today, even if you’re not sure you’ll ever need it.
| Date | What Happened | Who Was Present | What Your Child Said | How You Stored It |
|---|---|---|---|---|
| 3/14/26 | Son mentioned “Mike” sleeps at mom’s house “most nights.” First I’d heard of it. | Me and son, in my kitchen | “Mike made us breakfast again.” | Typed note, emailed to myself same day |
| 3/22/26 | Daughter came home with a bruise on her arm. Said Mike “grabbed her” during an argument. | Me, daughter, my girlfriend | “Mike got mad and grabbed me hard.” | Photo of bruise, typed note, both emailed to myself |
| 4/02/26 | Ex listed Mike as emergency contact on school form without telling me. | School office staff | N/A | Copy of form from school, saved to cloud drive |
Useful documentation is specific, dated, and stored somewhere you can’t accidentally lose it. Email it to yourself. Save it to a cloud drive. Write down exact quotes from your kids in their own words, not your interpretation. Keep the language neutral. “Son said Mike yelled at him” is usable. “Mike is an aggressive jerk who terrorizes my son” is not.
Useless documentation is vague, emotional, or written months after the fact. A judge reading “he’s always around and it’s stressing the kids out” learns nothing. A judge reading a dated entry with a direct quote and a witness learns everything.
The Next Step
If what you’re dealing with is closer to the “serious” side of that list, or if you’re not sure which side it’s on, don’t sit on it. Every week you wait is a week the record doesn’t exist. Schedule a consultation with In Law We Trust and we’ll walk through your specific situation, your parenting plan, and what a realistic next move looks like.
