The legal rights of minors sit on a sliding scale that ends at a single birthday. In nearly every state, that birthday is the 18th, and until it arrives the law treats a person as lacking full capacity to make binding decisions. The upside is a thick layer of protection: minors cannot be locked into most contracts, cannot be worked past strict hour limits, and are generally steered toward rehabilitation rather than adult punishment when they break the law. The downside is that minors cannot do many ordinary adult things, including getting a credit card in their own name or consenting to most medical care, without a parent in the loop.
When Someone Stops Being a Minor
The age of majority is the legal line between childhood and adulthood. Cross it and you gain the right to sign contracts, manage your own finances, make medical decisions, and vote. Most states set that line at 18, and federal statutes generally use the same threshold when defining who counts as a minor. There is no single federal law declaring 18 to be the universal age of majority; individual statutes just consistently land there.
Different rights, though, kick in at different ages. The 26th Amendment guarantees the right to vote at 18.1National Constitution Center. 26th Amendment – Right to Vote at Age 18 Federal highway funding law effectively pushes the minimum drinking age to 21 by withholding money from any state that lets people under 21 purchase alcohol.2Office of the Law Revision Counsel. 23 USC 158 – National Minimum Drinking Age A 17-year-old can enlist in the military with parental consent but cannot buy a beer for another four years.3Office of the Law Revision Counsel. 10 USC 505 – Regular Components Qualifications Term Grade Maturity, as the law sees it, is not a single switch.
Contracts a Minor Signs
Under longstanding common law, captured in the Restatement (Second) of Contracts § 14, a minor’s contractual duties are voidable until the day before the 18th birthday. The contract is not void automatically. It is voidable at the minor’s choice. The adult or business on the other side stays bound unless the minor decides to cancel.
A minor who does cancel generally has to return whatever they received. If the item was used, damaged, or lost, outcomes vary by court. That lopsided risk is why many businesses refuse to contract with minors outright, or require a parent to co-sign.
The Necessaries Exception
Minors cannot easily escape obligations for necessaries: food, clothing, shelter, basic medical care, and similar essentials. Buy these on credit and you owe the reasonable value of what was provided, even if you later try to void the deal. The rule exists so merchants will keep selling essentials to young people living on their own.
Ratification at 18
Contracts signed as a minor stop being automatically voidable the moment a person turns 18. If the now-adult keeps using the product, keeps making payments, or otherwise acts as though the contract is still alive, courts treat that behavior as ratification, and the contract becomes fully binding. Anyone who signed something as a teenager and wants out should move quickly after turning 18.
Work Rules by Age
Federal child labor rules under the Fair Labor Standards Act create a tiered system. 29 U.S.C. § 203(l) defines employment of anyone under 16 as “oppressive child labor” unless specific conditions are met.4Office of the Law Revision Counsel. 29 USC 203 – Definitions 29 U.S.C. § 212 then prohibits employers from using oppressive child labor in commerce or shipping goods produced with it.5Office of the Law Revision Counsel. 29 USC 212 – Child Labor Provisions
The limits break down by age:
- Under 14: generally cannot work in non-agricultural jobs, with narrow exceptions for things like delivering newspapers and acting.
- Ages 14 and 15: may work in approved occupations outside manufacturing and mining, within tight hour caps. On a school day, 3 hours. In a school week, 18 hours. When school is out, 8 hours a day and 40 hours a week. All work must fall between 7 a.m. and 7 p.m., except during summer when the evening cutoff extends to 9 p.m.6eCFR. 29 CFR 570.35 – Hours and Time Standards
- Ages 16 and 17: may work unlimited hours in non-hazardous jobs. The Department of Labor keeps a list of occupations declared too dangerous for anyone under 18, including operating many types of powered machinery, mining, and roofing.
Parents employing their own children under 16 are exempt from the oppressive-child-labor ban, as long as the work is not in manufacturing, mining, or a hazardous occupation.4Office of the Law Revision Counsel. 29 USC 203 – Definitions
Agriculture
Farm work follows its own framework under 29 U.S.C. § 213(c). Children as young as 12 can work on a farm with parental consent, and children under 12 can work on their parent’s own farm. All agricultural work by minors must take place outside school hours. Hazardous farm jobs are off-limits to anyone under 16, with an exception for children working on a parent’s farm.7Office of the Law Revision Counsel. 29 USC 213 – Exemptions
Money, Accounts, and Credit
Minors can own property and receive financial assets but cannot directly manage investment accounts or open bank accounts on their own. Two frameworks fill the gap: the Uniform Transfers to Minors Act (UTMA) and the older Uniform Gifts to Minors Act (UGMA). UGMA covers only cash and securities. UTMA expanded that to any type of property, including real estate.8Social Security Administration. Program Operations Manual System – Uniform Transfers to Minors Act
A custodian, often a parent or grandparent, manages the account. The minor is the legal owner the entire time, which matters for tax purposes. Once the minor reaches the age set by state law, the custodian hands over full control. There is no option to extend the arrangement because the now-adult beneficiary finds it inconvenient.
Credit Cards
A minor cannot get a credit card in their own name. Federal law bars issuing a credit card or opening a credit account for anyone under 21 unless they either show independent income or have a co-signer who is at least 21.9Office of the Law Revision Counsel. 15 USC 1637 – Open End Consumer Credit Plans Many card issuers let minors be added as authorized users on a parent’s account, which lets teenagers start a credit history without independent liability for the balance.
The Kiddie Tax
Investment income does not escape taxation because the owner is a child. Under 26 U.S.C. § 1(g), unearned income above a set threshold is taxed at the parent’s marginal rate instead of the child’s lower rate.10Office of the Law Revision Counsel. 26 USC 1 – Tax Imposed For 2026, the first $1,350 of a child’s unearned income is tax-free, the next $1,350 is taxed at the child’s own rate, and anything above $2,700 is taxed at the parent’s rate. The rule applies to interest, dividends, capital gains, and taxable scholarship income. It covers children under 18, and in some cases extends to students under 24 who do not earn more than half of their own support.
Medical Care and Privacy
Doctors generally need a parent’s informed consent before treating a minor. A 10-year-old cannot meaningfully weigh the risks and benefits of surgery or a course of medication. The rule has important exceptions, and they get broader as the child gets older.
Emergencies
When a minor arrives at an emergency room with a life-threatening condition and no parent is reachable, providers can and should treat them. Both state laws and medical ethics standards support treating minors in genuine emergencies without waiting for parental consent.
The Mature Minor Doctrine
Many states recognize that older teenagers, often 15 and above, may have the maturity to consent to their own medical care in certain situations. A provider who believes the teenager understands the risks and benefits can proceed without parental consent. This comes up most often with reproductive healthcare, mental health counseling, and substance abuse treatment, where fear of parental involvement might otherwise keep a teenager from seeking help at all.
HIPAA
Under HIPAA’s privacy rules at 45 CFR § 164.502(g), parents are generally treated as a minor’s personal representative and can access the child’s medical records.11eCFR. 45 CFR 164.502 – Uses and Disclosures of Protected Health Information General Rules When the minor has lawfully consented to care on their own, the parent’s access to those specific records can be restricted. The regulation carves out three situations where the minor controls the privacy: when the minor consented to the treatment and no other consent was required, when state law lets the minor obtain care without parental consent, and when the parent has agreed to a confidential relationship between the provider and the child.
Online Privacy for Children Under 13
The Children’s Online Privacy Protection Act defines a “child” as anyone under 13 and imposes strict rules on websites and apps that collect personal information from that age group.12Office of the Law Revision Counsel. 15 USC 6501 – Definitions Any site or online service directed at children, or that knows it is collecting data from a child, must post a clear privacy policy and must obtain verifiable parental consent before collecting, using, or disclosing a child’s personal information.13Office of the Law Revision Counsel. 15 USC 6502 – Regulation of Unfair and Deceptive Acts and Practices in Connection With Collection and Use of Personal Information From and About Children on the Internet That is why most social media platforms set their minimum sign-up age at 13, and why children’s apps require parental approval before a child can create an account. The FTC enforces COPPA and has levied multimillion-dollar fines against violators.
If a Minor Breaks the Law
Minors who break the law are generally processed through the juvenile justice system rather than adult criminal court. Juvenile proceedings focus on rehabilitation, with dispositions that can include counseling, community service, probation, and placement in juvenile facilities. The premise is that young people are more capable of change than adults.
That premise has limits. For serious violent offenses, most states allow or require a juvenile’s case to be transferred to adult court. The Supreme Court’s decision in Kent v. United States (1966) set out the factors judges weigh before ordering a transfer, including the seriousness of the alleged offense, whether it was violent and premeditated, the juvenile’s maturity and past record, and the prospects for rehabilitation. In most states, a minor must be at least 16 to be eligible for transfer, though some states set the floor lower for offenses like homicide.
A juvenile convicted in adult court faces adult sentencing, with constitutional limits on the harshest punishments. Life without parole for juvenile offenders is now restricted to the rarest cases, and the death penalty for crimes committed as a minor has been abolished entirely.
When Parents Are on the Hook
When a minor causes harm, through vandalism, shoplifting, or injuring someone, the legal consequences often reach the parents. Every state except the District of Columbia has a parental responsibility statute imposing some level of financial liability on parents for the intentional or willful acts of their minor children. These statutes typically cap damages, and the caps vary enormously. Some states limit recovery to $1,000 or $2,500. Others allow up to $25,000 or more. A few impose no specific dollar cap when the child’s act was willful or malicious.
Separately, parents can face direct liability under traditional negligence theory if they knew their child was dangerous and failed to supervise. A parent aware that their teenager has a pattern of starting fires and who does nothing to intervene can be held personally liable when the next fire damages a neighbor’s property. This type of claim has no statutory cap because the liability is based on the parent’s own negligence, not on vicarious liability for the child’s behavior.
Becoming a Legal Adult Early
Emancipation grants a minor adult status before the age of majority. Once emancipated, the individual can sign enforceable contracts, make their own medical decisions, lease an apartment, and handle every other legal matter that previously required parental involvement. In return, parents are released from the obligation to provide financial support.
Through the Courts
A minor seeking court-ordered emancipation typically has to show financial self-sufficiency, stable housing, and the maturity to justify ending parental control. Judges look at whether the minor has a reliable income, whether they understand the responsibilities they are taking on, and whether emancipation genuinely serves their interests rather than simply cutting them loose from a difficult family situation. Court filing fees generally range from about $280 to $435, and procedures vary by state. Not every state has a specific emancipation statute; in those that lack one, judges rely on common law.
Through Marriage or Military Service
In many states, marriage automatically emancipates a minor without any separate court proceeding. A legally married minor is treated as an adult for contract, property, and most other legal purposes. Minimum marriage ages with parental or judicial consent typically range from 15 to 17, depending on the state.
Military enlistment is more complicated. Federal law allows 17-year-olds to enlist with written parental consent.3Office of the Law Revision Counsel. 10 USC 505 – Regular Components Qualifications Term Grade Whether that enlistment results in automatic emancipation depends on state law. Some states treat military service as emancipation by operation of law. Others look at whether the minor’s parents continue providing financial support.
Emancipation is permanent. Once a court grants it or a qualifying event triggers it, there is no mechanism to reverse it. The minor becomes a legal adult with all corresponding rights and obligations, including the ability to be sued, the duty to pay taxes independently, and full accountability for their own decisions.
