In general, yes. Parents and legal guardians can supervise the phones of their minor children (under 18), and federal courts have accepted that a parent may consent to monitoring on a child's behalf when it is done in good faith to protect them. Two things change the answer: the person is an adult — including your own child once they turn 18 — or you want to record calls in one of the states that require everyone on the line to consent.
It is the question parents ask most about parental control, and the honest answer has layers. Reading a text message, seeing a location and recording a phone call are treated differently by the law, and so are a 12-year-old and a 19-year-old. This guide walks through federal law, the states with stricter rules and what courts have actually decided, so you can supervise your child without crossing a line.
The federal Wiretap Act (18 U.S.C. § 2511) makes it a crime to intercept someone's calls or electronic messages without consent, and it only requires the consent of one party to the conversation. Since 1998, federal appeals courts — starting with Pollock v. Pollock in the Sixth Circuit — have recognized that a parent can give that consent on behalf of a minor child. The condition is that the parent has a good-faith, objectively reasonable belief that monitoring is necessary for the child's welfare: safety, not curiosity. Reading messages already stored on a device you own and your child uses under your supervision is generally treated as authorized access under the Stored Communications Act (18 U.S.C. § 2701); breaking into an adult's account is not.
With a child under 18 who lives under your care, you can generally see their messages and chats, the apps they install, the sites they visit, their screen time and their location. The younger the child and the clearer the safety concern — an unknown adult contacting them, signs of bullying, self-harm or substance use — the stronger your position. Courts weigh the child's age and maturity and the reason for monitoring, so a 16-year-old gets more benefit of the doubt than a 10-year-old. The device usually being bought and paid for by you helps, but it is your role as parent, not the receipt, that gives you the right.
Federal law needs the consent of one party to a call, but about a dozen states require the consent of everyone on the line — among them California, Florida, Illinois, Maryland, Massachusetts, Montana, New Hampshire, Pennsylvania and Washington. When you record your child's call, the other person — often another parent's child, or an adult — has not consented, and vicarious consent has been accepted in some of these states but not tested in all of them. The prudent approach: in those states, do not record calls at all, or only with your child's knowledge and for a specific safety concern. Call logs, contacts and messages do not raise the same problem.
An adult child, a spouse, a partner, an ex or a roommate: monitoring an adult's phone without their explicit consent is a federal crime and a crime in every state, even if you pay the bill or own the device. Several states also have specific laws against installing spyware or "stalkerware", and the person can sue you for damages. Evidence obtained this way is not only inadmissible — it routinely backfires in divorce and custody cases. This is why CatWatchful requires the informed consent of any adult whose device is monitored.
For a minor, the law usually does not require it. Pediatricians, family therapists and family-law attorneys recommend it anyway, for two reasons. First, supervision that a teenager discovers by accident is experienced as a betrayal and tends to push them toward secrecy, which is the opposite of what you want. Second, a simple written family agreement — what is monitored, why, and until when — is the best proof of the "good faith" that courts look for if your monitoring is ever questioned. With younger children, direct supervision is natural; with teenagers, an explicit agreement works better than silence.
If custody is shared, the other parent keeps their rights too: monitoring the child is defensible, using the child's phone to keep tabs on your ex is not, and family courts treat it harshly. If a custody order says anything about devices or communication, follow it. Devices issued by a school are governed by the school's policy, which usually already includes monitoring; check before adding anything. And if your child has an emancipation order or is married, they are treated as an adult.
Check that your child is under 18 and that you are their parent or legal guardian. Use a device you own or that your child uses under your responsibility. Have a real safety reason and write it down. Talk to your child and, with teenagers, agree the rules in writing. In all-party-consent states, skip call recording or do it only with your child's knowledge. Keep what you see private — never share screenshots of a minor's conversations — and protect your account with a strong password. Stop, or switch to a consented arrangement, the day they turn 18.
Generally yes, as the parent or legal guardian of a minor, especially when you have a safety concern. Courts give older teenagers more privacy than young children, so the more mature your child is, the more it matters that you have a real reason and that they know the rules.
Under federal law and in most states, yes, through vicarious consent. In all-party-consent states such as California, Florida, Illinois, Maryland, Massachusetts, Montana, New Hampshire, Pennsylvania and Washington, the other person on the call has not consented, so the safest option is not to record calls, or to do it only with your child's knowledge for a specific safety reason. Call logs and messages do not raise this issue.
Yes, for a minor child in your care. Tracking an adult's location without consent — a partner, an ex, an adult child — is illegal and can amount to stalking under state law.
No. Monitoring another adult's phone without their explicit consent violates federal wiretap law and state law, and several states criminalize installing spyware specifically. It also tends to backfire badly in divorce and custody proceedings.
Not without their consent. Paying the bill or owning the device does not give you the right to monitor an adult. If they agree, in writing, that is a different situation.
Yes, when it is installed on the Android device of your own minor child, or on an adult's device with their informed consent. Any other use is illegal and violates the terms of service.
How to set it up as parental controlThis guide is general information about US law as of the review date, not legal advice. Laws change and differ between states. If your situation is unusual — a custody dispute, an emancipated minor, an all-party-consent state — talk to a family-law attorney licensed in your state.
