Age of Majority by State (2026): Custodial Account Guide

You've been diligently saving and investing for your child through a custodial account. Then one day you realize: in just a few years, they'll legally control all that money. The entire account—whether it's $5,000 or $50,000—becomes theirs to do with as they please.
When does that happen? At 18? 21? 25? The answer is: it depends on your state, the type of account you have, and sometimes even choices you made when opening the account.
This is the age of majority, and if you're investing for a child, understanding it is crucial. Because unlike a 529 plan where you maintain control, custodial accounts have a built-in expiration date—the day your child becomes a legal adult and takes ownership.
In this guide, I'll explain exactly what the age of majority is, how it differs from other legal ages (drinking, voting, etc.), when it applies to custodial accounts in every state, and most importantly, how to prepare your child for the responsibility of managing their inheritance.
What Is the Age of Majority? The Legal Definition
The age of majority is the legal threshold when a person transitions from being a minor (child) to an adult in the eyes of the law.
Why It's Called "Majority"
The term comes from the legal concept that adults are responsible for the majority of their actions. As an adult, you're accountable for most things you do—signing contracts, managing finances, facing legal consequences.
Conversely, "minor" describes someone responsible for only a minority of their actions. When a child is a minor, parents or legal guardians bear responsibility for most of their decisions and actions.
What Changes at the Age of Majority
When someone reaches the age of majority, they gain several legal rights and responsibilities:
Rights gained:
- Sign contracts without parental consent
- Open bank accounts in their own name
- Sue or be sued in court
- Make medical decisions
- Get married without parental permission (in most states)
- Own property and assets
- Control their own finances
- Make educational decisions
Responsibilities acquired:
- Legally responsible for their own actions
- Can be tried as an adult in criminal court
- Responsible for debts and contracts they sign
- Must manage their own finances
- No longer covered by parental obligation for support (in most states)
The Critical Point for Parents Investing for Kids
Here's what matters most for parents: If you've been investing for a child using a custodial account, when they reach the age of majority (or sometimes a state-specific age of termination), they gain full legal control over those assets.
This isn't optional. It's not something you can override by keeping the account in your name. The law requires the transfer of assets when they reach the designated age.
That's why understanding the age of majority in your state—and specifically how it applies to custodial accounts—is essential for anyone investing for children.
Age of Majority vs. Legal Age: What's the Difference?
This confuses almost everyone, so let's clear it up.
They're Not the Same Thing
Age of majority: The age when you become a legal adult generally, gaining most adult rights and responsibilities.
Legal age (or "age of license"): The specific age when you're legally allowed to do a particular activity.
You can reach the age of majority without reaching the legal age for certain activities, and vice versa.
Examples That Make It Clear
Let's say you live in California, where the age of majority is 18.
On your 18th birthday, you can:
- Sign a lease or mortgage
- Open a credit card
- Get married without parental consent
- Make your own medical decisions
- Vote in elections (federal legal age)
- Join the military (federal legal age)
- Buy lottery tickets (state legal age)
On your 18th birthday, you CANNOT:
- Buy alcohol (legal drinking age is 21 federally)
- Rent a car (most companies require age 25)
- Run for U.S. House of Representatives (must be 25)
- Run for U.S. Senate (must be 30)
- Run for President (must be 35)
Federal vs. State Legal Ages
Some legal ages are set federally (apply everywhere in the U.S.):
- Voting: 18 (26th Amendment)
- Drinking alcohol: 21 (National Minimum Drinking Age Act)
- Buying tobacco/vaping products: 21 (federal law as of 2019)
Other legal ages vary by state:
- Driving: Unrestricted license age ranges from 16-18 depending on state
- Marriage: Varies with and without parental consent
- Age of consent: Ranges from 16-18 across states
- Gambling: Varies (18 or 21 depending on state and type)
Why This Matters for Custodial Accounts
The age of majority (or a related age of termination) determines when a child takes control of their custodial account—not the legal drinking age, voting age, or any other specific legal age.
This means your child might control $30,000 in investments at age 18 but still can't legally buy a beer. Understanding this disconnect is important for setting expectations.
What Is the Age of Majority in My State?
While the federal government sets certain legal ages (voting, drinking), each state determines its own age of majority.
The Standard Age: 18
In most U.S. states, the age of majority is 18. This became the norm in the 1970s when many states lowered it from 21, partially in response to the 26th Amendment lowering the voting age to 18.
States where age of majority is 18 (most states): Alabama, Alaska, Arizona, Arkansas, California, Connecticut, Delaware, Florida, Georgia, Hawaii, Idaho, Illinois, Iowa, Kansas, Kentucky, Louisiana, Maine, Massachusetts, Michigan, Minnesota, Missouri, Montana, Nevada, New Hampshire, New Jersey, New Mexico, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, Washington, West Virginia, Wisconsin, Wyoming
Exceptions: 19 and 21
Age of majority is 19:
- Alabama
- Nebraska
Age of majority is 21:
- Colorado
- Mississippi
Note: Some sources list different ages for certain states because they distinguish between general age of majority and specific rights (like alcohol consumption or custodial account termination). We're focused on the general age of majority here.
Special Cases: Emancipation
Even if someone hasn't reached the age of majority, they can become a legal adult earlier through emancipation.
Emancipation is a legal process where a minor petitions the court to be declared an adult. Reasons include:
- Desire to live independently from parents
- Getting married (in states that allow minor marriage)
- Joining the military
- Financial independence
- Unsafe home environment
Once emancipated, the minor gains adult rights and responsibilities immediately, including control over any custodial accounts.
Age of Majority for Custodial Accounts: It Gets Complicated
Here's where things get more nuanced. The age when a child takes control of a custodial account isn't always the same as the general age of majority.
Two Types of Custodial Accounts
UGMA (Uniform Gift to Minors Act):
- Available in all 50 states
- Can hold financial assets: cash, stocks, bonds, mutual funds, ETFs
- Generally simpler rules
UTMA (Uniform Transfers to Minors Act):
- Available in most states (but not all)
- Can hold financial assets PLUS real estate, art, patents, and other property
- Often has later age of termination
- More flexibility for custodians

Age of Majority by State for Custodial Accounts
This is where you need to pay close attention. The age when your child gains control of their custodial account varies significantly.
Key Takeaways from the Tables
UGMA accounts:
- Most states: Age 18 or 21
- More uniform across states
- Generally cannot be extended beyond state law
UTMA accounts:
- Range from 18 to 25
- Much more variation
- Some states allow custodian to choose age within a range
States Where You Choose the Age (UTMA)
In these states, the custodian can select when the account terminates (within the given range):
Alaska: 18-25 (custodian chooses) Arkansas: 18-21 (custodian chooses) California: 18-25 (custodian chooses, must choose at account opening) Maine: 18-21 (custodian chooses) Nevada: 18-25 (custodian chooses) New Jersey: 18-21 (custodian chooses) North Carolina: 18-21 (custodian chooses) Virginia: 18-21 (custodian chooses)
Critical point: In most cases, you must make this choice when opening the account. You typically cannot change it later.
The Discrepancy That Surprises Parents
Here's a common scenario that catches parents off guard:
You live in Wyoming, where the general age of majority is 18. Your child turns 18 and assumes they now control their custodial account. However, if it's a UTMA account, the age of termination in Wyoming is 21.
This means:
- Age 18: Your child is a legal adult for most purposes
- Age 18: Your child still doesn't control their UTMA account
- Age 21: Custodianship terminates and they gain control
Why this matters: You need to be clear with your child about expectations. Just because they're legally an adult doesn't mean they automatically get access to their investment account.
Checking Your Specific Account
To know exactly when your child will gain control:
- Check your account opening documents - The age of termination should be specified
- Contact your account provider - They can tell you the specific age for your account
- Verify your state's current laws - Laws can change, though this is rare
Don't assume—verify. This is too important to guess.
What Happens When Your Child Reaches the Age of Majority?
Two major transitions occur: transfer of rights and transfer of assets.
Transfer of Rights: Automatic
This happens automatically on your child's birthday when they reach the age of majority.
What changes immediately:
- They can sign legal contracts
- They're responsible for their own legal actions
- They can make medical decisions
- They can access their own educational records
- Parents are no longer legally required to support them (in most states)
- They're tried as adults if accused of crimes
What doesn't change immediately:
- Control of custodial accounts (if age of termination differs)
- Ability to drink alcohol (if under 21)
- Ability to rent cars (most companies require 25)
- Insurance rates (may stay on parent's plan until 26 under ACA)
For parents, this means: You no longer have legal authority to make decisions for your child, even if you're still financially supporting them. This includes accessing their medical records, speaking to their college professors about grades, or making financial decisions on their behalf.
Transfer of Assets: Process Required
Unlike the automatic transfer of rights, the transfer of custodial account assets requires an active process.
How it typically works:
Step 1: Notification Most account providers notify both the custodian and the beneficiary several months before the age of termination. This gives everyone time to prepare.
Step 2: Account freeze Around the termination date, the account may be temporarily restricted. The custodian can no longer make trades or withdrawals while the transfer is processed.
Step 3: Documentation The beneficiary (now legal adult) must provide:
- Proof of identity (driver's license, passport)
- Social Security number verification
- Possibly tax forms (W-9)
- New account application (if converting account type)
Step 4: Asset transfer The provider transfers ownership. This might mean:
- Converting the custodial account to a standard brokerage account in the child's name
- Transferring assets to a new account the child opens
- Liquidating and distributing cash (rare, usually only if child requests)
Step 5: Complete control Once processed, your child has 100% control. They can:
- Trade stocks
- Withdraw funds
- Close the account
- Change investment strategy
- Do anything else an account owner can do
Timeline for the Transfer Process
Typical timeline:
- 3-6 months before: Notification sent
- 1-2 months before: Account restrictions may begin
- Birthday: Legal transfer occurs
- 1-4 weeks after: Physical transfer of account control completed
Important: The exact timeline varies by provider. Some are faster, others slower. Contact your provider to understand their specific process.
What Your Child Can Do with the Money
This is what worries many parents: Once the transfer is complete, your child can use the money however they want.
They can:
- Pay for college tuition and expenses
- Make a down payment on a house
- Start a business
- Invest it differently
- Buy a car
- Take a trip around the world
- Spend it on whatever they choose
You cannot:
- Block the withdrawal
- Add conditions to the use
- Require they use it for education
- Prevent them from spending it
This is fundamentally different from a 529 plan, where you maintain control and the money must be used for education.
How to Prepare Your Child for This Responsibility
The age of majority will arrive whether you're ready or not. Here's how to ensure your child is prepared to handle their inheritance responsibly.
Start Financial Education Early
Don't wait until they're 17 to start talking about money. Teaching kids about money should begin in childhood.
Ages 5-10: Money basics
- Where money comes from (work)
- Saving vs. spending
- Basic budgeting
- Delayed gratification
Ages 11-14: Expanding concepts
- How interest works
- What investing means
- Understanding risk
- The power of compound growth
Ages 15-18: Advanced preparation
- Show them the actual account
- Explain what's invested and why
- Discuss what happens at age of majority
- Talk about responsible use of inherited assets
- Help them create a plan for the money
Involve Them in Financial Decisions
The best education is hands-on experience.
Practical steps:
Share your budget Once they're old enough (14+), show them your family budget. Explain how you allocate money, prioritize spending, and plan for the future.
Let them manage money Give them increasing responsibility:
- Ages 10-13: Manage their own allowance or earnings
- Ages 14-16: Budget for their own clothing or entertainment
- Ages 17-18: Pay for some of their own expenses (phone bill, gas)
Show them the custodial account Starting around age 14-15, periodically log in together and review:
- Current balance
- How it's invested
- How much it's grown
- What it could be worth by age 18/21/25
Have the "what will you do with this money" conversation Don't wait until the last minute. By age 16-17, have serious conversations about:
- What are their goals?
- How might they use these funds?
- What would be wise vs. unwise uses?
- Do they understand the opportunity cost of spending vs. continuing to invest?
Create a Plan Together
About 1-2 years before the age of termination, sit down and create a specific plan.
Questions to discuss:
- What are your financial goals?
- Education
- Starting a business
- Down payment on a home
- Building emergency fund
- Continue investing for retirement
- How much do you need in the next 2-5 years?
- Calculate realistic needs
- Leave the rest invested for long-term growth
- What's your withdrawal strategy?
- Take it all out immediately? (Usually not wise)
- Leave it invested and withdraw as needed?
- Transfer to different accounts for different goals?
- Do you understand the tax implications?
- Withdrawals may trigger capital gains taxes
- Timing of withdrawals matters
- Should you consult a tax advisor?
The goal: By the time they gain legal control, they should have a thoughtful plan—not just "I don't know, I'll figure it out."
Consider a Gradual Transition
While you can't legally prevent the full transfer at the age of majority, you can structure things to ease the transition.
If opening a new UTMA in a state that allows custodian choice: Consider choosing an older age (21 or 25 vs. 18) to give your child more time to mature.
Discuss setting up sub-accounts: Once they gain control, suggest they immediately:
- Transfer a portion to a high-yield savings account (emergency fund)
- Keep long-term money in investments
- Only keep near-term needs in accessible cash
Introduce them to a financial advisor: Before the transfer, connect them with a financial advisor who can provide professional guidance. Many will offer a free initial consultation.
Set Expectations About Continued Support
Be clear about what financial support (if any) you'll continue providing after they reach the age of majority.
Topics to clarify:
- Will you continue paying for college?
- Will you cover health insurance?
- Will they live at home rent-free?
- What expenses become their responsibility?
This prevents the "I have $20,000 in my account, so I'll quit my part-time job and spend it" mindset.
Common Questions About Age of Majority
"Can I change the age of termination after opening the account?"
In most cases, no. The age of termination is typically set when you open the account and cannot be changed later. Some states that allow a range let you choose within that range at opening, but once set, it's locked.
"What if I don't trust my child to handle the money responsibly?"
This is a legitimate concern. Options include:
- Choose a UTMA over UGMA in states where you can set a later age (21 or 25)
- Start with smaller contributions and use a different vehicle (529, trust) for larger amounts
- Focus heavily on financial education in the years leading up to termination
- Consider setting up a trust instead, which gives you more control
"Can I just keep the account in my name and give them money as needed?"
No. Legally, a custodial account belongs to the child. When they reach the age of majority/termination, the assets must transfer. Failing to do so is legally problematic and could have tax consequences.
"What happens if my child has special needs?"
Special needs trusts or ABLE accounts might be better options than custodial accounts, as they preserve eligibility for government benefits. Consult with a special needs financial planner.
"Do I have to tell my child about the account?"
Legally, once they reach the age of majority, they have a right to know about and access their assets. Ethically and practically, it's better to involve them beforehand so they're prepared.
"Can they access the account before the age of termination?"
No. Until they reach the designated age, the custodian maintains full control. The child has no legal right to request withdrawals or changes.
"What if they want to use it all for something frivolous?"
Once it's transferred, it's their decision. This is why education and planning beforehand are so critical. You can advise, but you cannot control.
The Bottom Line on Age of Majority
Understanding the age of majority is crucial for anyone investing for a child's future. Here's what you need to remember:
For general purposes:
- Most states: Age of majority is 18
- Alabama, Nebraska: Age 19
- Colorado, Mississippi: Age 21
For custodial accounts:
- UGMA: Usually 18 or 21
- UTMA: Ranges from 18 to 25 depending on state
- Some states let custodian choose within a range
- Check your specific account—don't assume
What happens:
- Transfer of rights: Automatic on birthday
- Transfer of assets: Requires process, usually 1-4 weeks
- Your child gains complete control of the money
- You cannot prevent or control how they use it
How to prepare:
- Start financial education young
- Involve them in money decisions
- Show them the account before transfer
- Create a plan together 1-2 years in advance
- Consider professional financial advisor consultation
The key insight: The age of majority isn't something that happens to you—it's something you prepare for. Starting that preparation early makes all the difference.
Getting Started with Long-Term Investing for Kids
If you're ready to start investing for a child's future, understanding the age of majority helps you make informed decisions about which account type makes sense for your family.
Custodial accounts offer powerful benefits:
- Tax advantages (first $1,350 of earnings tax-free)
- No contribution limits (unlike 529s or IRAs)
- Complete flexibility in use (unlike 529s restricted to education)
- Opportunity to teach children about investing
The trade-off is that mandatory transfer of control when they reach the age of termination. For families committed to financial education, this becomes less concerning—you're raising a financially responsible adult who will use their inheritance wisely.
At NestEgg, we make it simple to start a custodial account and involve your child in the journey. As they grow, you can show them how their account is growing, explain the investments, and prepare them for the day when they take control.
Start investing for your child today and build both a financial foundation and the wisdom to use it well.
