You generally do not have a legal right to know who your ex brings around your child during their parenting time. Family courts treat that as a day-to-day parenting decision, and each parent controls their own household when the child is with them. The exception is what your custody order says: if it includes a notification clause, a morality clause, or a right of first refusal, those terms are enforceable. And if a specific person poses a real safety risk to your child, a court can step in regardless of what the order says.
The Default Rule During Your Ex’s Parenting Time
Family courts across the country recognize that each parent makes routine, day-to-day decisions when the child is in their care. Who eats dinner with the child, which friends come over, and whether a new partner is present all fall on the day-to-day side. This is often called parental autonomy, and it means your ex does not need your permission to have other adults around your child during their custody time.
The law separates day-to-day choices from major decisions. Major decisions, like education, medical care, and religious upbringing, are typically shared or allocated in your custody order. Choosing who to invite over for a barbecue is not one of them. Courts assume each parent will act in the child’s best interest, and personal disapproval of a new partner, without more, is not enough to override that assumption.
What Your Custody Order Can Actually Require
Your custody order or parenting plan is the one document that can change the default. If you want the right to know about or limit who your ex has around your child, those terms need to be in writing. Three provisions are worth knowing about.
Notification Clauses
Some custody agreements require each parent to notify the other before introducing a new romantic partner to the child. These clauses don’t ban contact; they just require a heads-up. The specifics vary. Some require written notice a certain number of days in advance. Others simply require the other parent to be informed at some point before or shortly after the introduction. If your agreement is silent, the default parental autonomy rule applies and your ex has no obligation to tell you anything about who they’re dating.
Morality Clauses
A morality clause, sometimes called a paramour clause, typically prohibits either parent from having an unmarried romantic partner stay overnight while the child is home. Language varies. Some clauses ban overnight guests of any kind. Others restrict only romantic partners. A few prohibit introducing a new partner to the child until the relationship has lasted a set number of months.
Enforcement is the hard part. Proving a violation usually takes more than suspicion. And if your ex marries the new partner, the clause typically becomes irrelevant, because it applies only to unmarried partners. When you can show a clear violation, though, you have grounds to bring the matter back to court.
Right of First Refusal
A right of first refusal clause gives you the first opportunity to watch your child when your ex can’t be present during their scheduled parenting time. Instead of leaving the child with a new partner, babysitter, or family member, your ex has to offer that time to you first.
These clauses aren’t automatic. They exist only if both parents agree to include them or a judge orders one. Most states don’t have a statute requiring them. The important detail is the time threshold that triggers the obligation. Some agreements set it as low as a few hours; many parents settle on between five and eight hours, which captures overnight absences and full-day trips without generating conflict over every errand. A well-drafted clause spells out what counts as an absence requiring notice, how quickly the other parent must respond, and how the child will be exchanged.
If you’re still negotiating your custody order, adding one of these provisions now is far easier than trying to insert it later.
When a Court Will Restrict Who’s Around Your Child
Courts don’t intervene because you dislike your ex’s new partner. To get a judge involved, you have to show that a specific person’s presence is causing, or is likely to cause, real harm. The standard is the best interests of the child, and courts weigh factors like physical safety, emotional health, stability, and each parent’s ability to provide a safe environment.
Evidence that tends to move a judge includes:
- Criminal history, especially convictions for violent crimes, domestic abuse, or offenses against children. Courts take this particularly seriously when the person is a registered sex offender.
- Documented substance abuse that creates an unsafe environment, such as intoxication during caregiving or drug use in the home.
- Abusive behavior toward the child, including physical discipline, verbal abuse, or other mistreatment.
- A measurable impact on the child, such as behavioral changes, declining school performance, anxiety, or statements the child has made to teachers, therapists, or other trusted adults.
The burden falls on the parent asking for the restriction. Vague discomfort or a gut feeling isn’t enough. Judges see many cases where one parent simply disapproves of the other’s choices, and they’re practiced at distinguishing personal grievances from real safety concerns. If you’re going to make the argument, bring specifics.
How to Check Out a New Partner
Before you file anything, there’s information you can gather on your own.
Sex Offender Registry
The Dru Sjodin National Sex Offender Public Website is a free federal resource run by the U.S. Department of Justice that lets you search sex offender registries across all states, territories, and tribal lands.1NSOPW. About NSOPW You can search by name, zip code, address, or county.2NSOPW. Search Public Sex Offender Registries A free mobile app is also available. A hit on the registry is powerful evidence in any custody proceeding.
Public Court Records
Most state and county courts maintain online databases of criminal and civil case records that anyone can search for free or for a small fee. A name search can reveal criminal convictions, restraining orders, or pending charges. These are public records, and using them is entirely legal.
The Limits on Formal Background Checks
If you’re thinking about hiring a background screening company, be aware that the Fair Credit Reporting Act limits who can pull a formal consumer report. Under federal law, consumer reporting agencies can only provide reports for specific purposes, including employment, credit, insurance, and certain government licensing decisions.3Office of the Law Revision Counsel. United States Code Title 15 – Section 1681b Checking up on your ex’s new partner is not on that list. Public records searches and registry checks are open to everyone; a formal consumer report is not.
Keep a Written Record
Document what you see and hear. Save text messages and emails where your child describes concerning incidents. Note dates, times, and details. If a teacher, pediatrician, or therapist has observed behavioral changes, ask them to document those observations. Courts weigh specific, dated evidence far more than general allegations.
Going Back to Court
If conversation with your ex doesn’t resolve things and the evidence supports court involvement, the formal path is a motion to modify your custody order. Most jurisdictions require you to show a material change in circumstances before a court will revisit an existing order. This requirement exists to protect children from constant relitigation.
A new partner with a violent criminal history moving into your ex’s home could qualify. Your ex dating someone you find annoying almost certainly would not. The change needs to be significant, ongoing, and connected to the child’s well-being. Many courts require mediation before a modification hearing, and in some cases the court will appoint a guardian ad litem, an independent advocate who investigates and makes recommendations focused on the child.
Filing fees, attorney fees, and mediation costs add up quickly, so have a realistic conversation with a family law attorney about the strength of your case before you commit.
Emergency Orders When a Child Is in Immediate Danger
The standard modification process takes time you may not have. Every state has a procedure for requesting emergency or temporary custody orders when a child faces an imminent threat of harm, abuse, or abduction. These orders can sometimes be granted the same day or the next business day. Examples that meet the bar include discovering your child is living with someone charged with child abuse, seeing signs of physical harm after a custody exchange, or learning the new partner has active warrants for violent offenses.
If you believe your child has been abused or is in immediate physical danger, don’t wait for a court date. Call 911. You can also contact the Childhelp National Child Abuse Hotline at 800-422-4453, which is available around the clock and can walk you through reporting to your local child protective services agency.4Child Welfare Information Gateway.

Enforcing Terms You Already Have
If your custody agreement already contains restrictions on third-party contact, overnight guests, or notification requirements, and your ex is ignoring them, that’s potentially contempt of court. Penalties can include fines, jail time, makeup visitation, payment of your attorney fees, and, in cases of repeated violations, modification of the custody arrangement itself.
You enforce these provisions by filing a contempt motion. You file paperwork, serve the other parent, and present evidence at a hearing. You’re not asking the court to change the order; you’re asking the court to enforce what’s already there. When the evidence clearly shows a violation, judges tend to take enforcement seriously, because their authority depends on their orders being followed.
