Is It Legal to Track Your Child With GPS?

A U.S. parent’s guide to child GPS tracking laws, consent, custody, and doing it the right way.

Short answer: Yes. In the United States, it is generally legal for a parent or legal guardian to use GPS to
track their own minor child. Your custodial authority gives you the right to know where your child is. The
legal gray areas appear in three situations: when your child becomes a legal adult, when you share
custody with another parent, and when tracking is done secretly to monitor another adult rather than to
protect your child.

Between smartwatches, phone apps, and dedicated GPS trackers, keeping tabs on your child has never been easier.
But easy is not the same as lawful, and “can I” is a different question from “should I.” If you have ever paused before slipping a tracker into your kid’s backpack and wondered whether you are within your rights, you are asking exactly the right question.
This guide breaks down the U.S. legal picture in plain language: where your rights as a parent are strongest, where the law draws hard lines, and how to track your child in a way that keeps you on the right side of both the law and your child’s trust.

by state and change over time. For guidance on your specific situation — especially during a divorce or
custody dispute — consult a licensed family law attorney in your state

Why parents generally have the right to track a minor child

The foundation is custodial authority. Parents and legal guardians have broad legal control over their minor children, and courts have consistently recognized that this includes the right to govern where a child goes.
The U.S. Supreme Court, in Bellotti v. Baird (1979), noted that children’s constitutional rights are not identical to those of adults, citing their vulnerability, their limited capacity for mature decisions, and the importance of the parental role. In practice, that means a young child or teenager has a limited expectation of privacy against their own parents.

There is very little law written specifically about parents and GPS. Where laws restrict tracking devices, they are aimed at protecting people from being tracked by outsiders or by other adults — not at stopping a parent from safeguarding a minor.
So when the tracker is on a phone or device you own, tracking your own child in your own care sits on solid legal ground.

Where the law draws the line

Three factors turn a clearly legal situation into a legally risky one. Understand these and you understand
almost the entire topic

Your child’s age
The clearest bright line is the age of majority — 18 in most states. Once your child is a legal adult, your parental authority ends, and tracking them without their knowledge and consent can expose you to the same privacy and stalking laws that apply to any two adults.
Heading off to college does not change this; an 18 year-old is legally an adult even if you are still paying the phone bill. If you want to keep location sharing after 18, ask for it and set it up together.
Shared custody and co-parenting
This is the single most common place parents get into legal trouble. If you share custody, your authority generally covers the time your child is in your care — not the other parent’s parenting time.
Secretly planting a tracker on your child to monitor them during your ex’s visitation can be treated as an invasion of privacy, and in some cases as stalking or harassment of the other parent. Family courts decide based on the child’s best interests, and a parent caught covertly surveilling the other parent’s time rarely looks good in front of a judge.
Some states make the risk explicit. Florida law, for example, presumes that consent to tracking is revoked once one spouse files for divorce or an injunction for protection. The safe path in a co-parenting arrangement is a written agreement or a court order that spells out whether, how, and when a child may be tracked.
State tracking and “anti-stalking” statutes
At least 26 states and the District of Columbia regulate the private use of location-tracking devices. In about adozen states these rules live inside stalking or cyberstalking laws; in others they specifically ban placing a GPS device on a vehicle without the owner’s consent.
Crucially for parents, several of these statutes include an explicit exception for a parent or guardian tracking a minor child — Delaware, Michigan, and Tennessee
among them. Others hinge on who owns the vehicle or device. Because the details differ so much from state to state, it is worth a two-minute check of your own state’s law before you rely on a tracker in a contested situation.

Legal monitoring is not the same as secret spying. Even when tracking a minor is perfectly lawful, doing it
covertly can backfire — legally if the child is close to 18, and personally if your child feels ambushed. For
teenagers especially, transparency is both the safer legal posture and the smarter parenting move. Telling
your child “we use location sharing as a family for safety” is very different from hiding a device and hoping
they never find it.

Common situations, quickly answered

Teen drivers. Tracking a vehicle you own that your teen drives is generally legal and is one of the most defensible uses. If your teen owns the car outright, be more careful — vehicle-ownership rules can apply.
Young children and kids with special needs. Tracking a young child or a child with autism or a cognitive disability is on the strongest possible footing; safety devices for these families are widely accepted and, in wandering-risk cases, potentially lifesaving.
Older teens (16–17). Still legal, but the case for openness grows as they approach adulthood. Treat it as a conversation, not a stakeout.
Tracking through the other parent’s time. High risk. Get consent or a court order first.
Adult children (18+). Consent required. No exceptions based on who pays for the phone.

How to track your child legally and ethically

A simple framework that keeps you compliant and preserves trust:

Track your own minor child on a device or vehicle you own.
Be transparent — tell age-appropriate children that location sharing is on, and why.
Stop, or get consent, once your child turns 18.
In shared custody, put tracking in writing — a parenting-plan clause or court order.
Never use a child’s tracker as a backdoor to monitor another adult.
Check your state’s tracking statute if your situation is contested.

When it crosses into illegal territory

Frequently asked questions

Can I track my child’s phone without them knowing?
For a minor in your care, generally yes — but the older the child, the more transparency is advised, and oncethey turn 18 you need consent.
Is it legal to put a GPS tracker in my teenager’s car?
If you own the vehicle, this is one of the most defensible uses. If your teen owns the car, check your state’s vehicle-tracking rules first.
Can I track my child when they’re with my ex?
This is legally risky. Tracking a child during the other parent’s custody time without consent or a court ordercan be treated as invasion of privacy or stalking. Get it in writing first.
At what age do I have to stop?
At the age of majority — 18 in most states. After that, your child is an adult and tracking requires their
consent.

The bottom line: tracking your own minor child for their safety is legal across the U.S. The law only pushes
back when tracking outlives your child’s childhood, reaches into another parent’s custody time, or becomes a
tool for watching another adult. Stay inside those lines — be transparent, respect the age-18 threshold, and
get consent when custody is shared — and GPS becomes exactly what it should be: a quiet layer of protection
for the people you love most.
