The legal age in Mississippi is 21. Mississippi is the only state that still sets its general age of majority that high, which means anyone under 21 is classified as a “minor” for many purposes under state law.1Justia. Mississippi Code 1-3-27 – Minor But 21 is not the only age that matters. Federal law and several Mississippi statutes give younger residents specific rights well before then, so the practical answer depends on which right you’re asking about.
What You Can Do at Each Age
Rights arrive on a schedule in Mississippi. The main milestones:
- Age 14: Federal child labor rules begin to allow limited employment. Mississippi separately bars children under 14 from working in mills, canneries, workshops, factories, or manufacturing facilities.2Justia. Mississippi Code 71-1-17 – Children Under Fourteen Not to Work in Mills or Factories
- Age 15: You can apply for a learner’s permit with proof of school enrollment. The permit costs $7 and is valid for two years; all driving must be supervised. A 15-year-old female with parental consent may also marry under state law. Minors 15 and older can consent on their own to mental health treatment related to alcohol or drug use.3DPS Driver Service Bureau. Regular Learners Permit4Justia.

Mississippi Code 41-41-14 – Physician Treating Minor for Mental or Emotional Problems Resulting From Alcohol or Drugs Need Not Obtain Parental Consent
- Age 16: After holding a permit for at least 12 months, you can get an intermediate driver’s license ($24 for four years). For the first six months or until you turn 17, unsupervised driving is barred between 10 p.m. and 6 a.m. Sunday through Thursday, and between 11:30 p.m. and 6 a.m. Friday and Saturday. Sixteen is also the effective age of sexual consent under the statutory rape law.6MDOT. Parent-Teen Driving Agreement7Justia. Mississippi Code 97-3-65 – Statutory Rape
- Age 17: Intermediate driving restrictions drop, and you can obtain a permit and full license on the same day. Males may marry at 17 with parental consent. Seventeen-year-olds can also vote in primary elections if they will be 18 by the general election.3DPS Driver Service Bureau. Regular Learners Permit4Justia. Mississippi Code 93-1-5 – Conditions Precedent to Issuance of License
- Age 18: You can vote in general elections, make your own medical decisions under the state’s Uniform Health-Care Decisions Act, sign contracts for real or personal property, and buy a rifle or shotgun from a licensed dealer.8Office of the Law Revision Counsel. 18 US Code 922 – Unlawful Acts
- Age 21: You reach the general age of majority. You can buy alcohol and tobacco, purchase a handgun from a licensed dealer, marry without parental consent, serve on a jury, and enter any contract without the disability of minority.
The Gap Between 18 and 21
The 18-to-21 stretch is where Mississippi’s rules get complicated, because state law treats an 18-year-old as an adult for some purposes and a minor for others.
At 18 you can vote. The 26th Amendment sets that floor and no state can raise it. You can also consent to your own medical care; the Uniform Health-Care Decisions Act defines “adult” as anyone 18 or older, so parental consent is no longer required and you can execute a healthcare power of attorney. Property contracts follow the same line: the minor statute carves out an exception saying “minor” means under 18 for contracts involving real property or personal property, so an 18-year-old can sign a deed or a lease without parental involvement.1Justia. Mississippi Code 1-3-27 – Minor Federal firearms law lets an 18-year-old buy a long gun from a dealer, though not a handgun.8Office of the Law Revision Counsel. 18 US Code 922 – Unlawful Acts
For most other purposes, though, you’re still a minor until 21. That includes non-property contracts, marriage without parental consent, jury service, and the state’s general age-of-majority rules.
What Still Requires You to Be 21
Several rights and privileges wait until you hit the full age of majority.
Alcohol. You must be 21 to buy or possess alcohol. Possessing alcohol in a public place while under 21 is a misdemeanor carrying a fine between $200 and $500.9Justia. Mississippi Code 67-1-81 – Sales to Minors Prohibited A judge may suspend the minor’s driver’s license for up to 90 days in place of the fine.10Justia. Mississippi Code 67-3-70 – Purchase of Light Wine or Beer by Minors
Tobacco and nicotine products. Buyers must be at least 21. Sellers must check a government-issued photo ID for anyone who appears to be under 27.11Justia. Mississippi Code 97-32-51 – Sale of Alternative Nicotine Products
Handguns from a dealer. A licensed dealer cannot sell a handgun to anyone under 21.8Office of the Law Revision Counsel. 18 US Code 922 – Unlawful Acts Private sales between individuals are subject to different rules, and Mississippi does not add its own minimum age beyond the federal one.
Marriage without parental consent. Anyone under 21 needs parental or guardian consent before a circuit clerk will issue a marriage license.4Justia. Mississippi Code 93-1-5 – Conditions Precedent to Issuance of License
Jury service. You must be 21 to sit on a jury. An 18-year-old can vote for the officials who write the laws but cannot serve on a jury that applies them.
Non-property contracts. For contracts that don’t involve real or personal property, Mississippi treats anyone under 21 as a minor with limited capacity to enter binding agreements.1Justia. Mississippi Code 1-3-27 – Minor Minors can generally walk away from such contracts either during minority or within a reasonable time after turning 21. The main exception is necessities like food, clothing, medical care, and shelter, for which a minor remains liable for the reasonable cost.
Consent for Medical Treatment of Minors Under 18
When an unemancipated minor under 18 needs medical treatment, Mississippi law sets a priority list of people who can consent: first a guardian or custodian, then a parent, then an adult sibling, then a grandparent.12Justia. Mississippi Code 41-41-3 – Consent for Surgical or Medical Treatment or Procedures on Unemancipated Minors If none of those people are available, any adult who has shown special care for the minor may consent. The same statute allows any female, regardless of age or marital status, to consent to her own care related to pregnancy or childbirth.
Child Support Runs Until 21
Because the age of majority is 21, a parent’s duty to pay child support in Mississippi generally continues until the child turns 21. Support can end earlier if the child gets married, enters full-time military service, or is convicted of a felony and sentenced to at least two years of incarceration. A judge may also end support if the child turns 18, leaves school, and has no disability, or if the child moves out, works full-time, and stops pursuing education. Any back child support owed from before emancipation must still be paid in full.
Ending Minor Status Before 21
A minor who wants legal independence before 21 can petition the chancery court to “remove the disability of minority.” A successful petition lets the minor handle real estate, sign contracts, and manage their own affairs as if they were 18.13Justia. Mississippi Code 93-19-1 – Removal of Disability of Minority The petition is filed in the chancery court of the county where the minor lives. Marriage also triggers emancipation for child support purposes, though it operates under a different statute.
