Using Custodial Funds for Life Starts: A First Car, a Wedding, or a First Home

In 2010, a Pennsylvania mother withdrew $253,000 from the custodial accounts she managed for her two teenagers and bought a $235,000 house. She titled it in her own name. When the children, by then 18 and 19, sued for an accounting in 2013, the house had just sold for double what she paid. The trial court sent all of the proceeds to the children’s accounts, even though there was evidence she had put some of her own money into it, and in 2016 Pennsylvania’s Superior Court affirmed, according to a summary of Werner v. Werner by Mark R. Ashton, an attorney at Fox Rothschild. One of the children never lived in the house, and while the case played out, the children essentially paid their own way through college.

The trouble wasn’t that custodial money bought a house. It was whose house it was. That’s the rule behind every life start in this guide: money in a custodial account belongs to your child, so whatever it buys, whether a first car, a wedding, or a first home, has to be your child’s.

For most families, the bigger question is timing. A custodial account changes hands at its termination age, usually 18 or 21, and up to 25 in many states, according to Saving for College. The big life starts tend to come later. The median age at first marriage reached 28.4 for women and 30.8 for men in 2025, according to the Census Bureau, and the median first-time home buyer was 40, a record, in the National Association of Realtors’ 2025 survey. By the time most of these milestones arrive, the account is no longer yours to manage.

This guide is part of The Hand-Off: Safely Withdrawing and Transitioning Wealth, the hub for the final phase of GoodNest’s guides. It covers what custodial money can pay for before and after the hand-off, how to sell investments without overpaying tax, a playbook for each of the three big life starts, and how to help from your own savings. The “Wealth Transfer” Conversation has a script for talking it all through with your child.

Whose money is it by then?

Every custodial account runs in two phases. Until its termination age, a custodian manages the money for your child. After it, your child does. Which phase you’re in decides who makes the call on a car, a wedding, or a house.

Before the hand-off, you decide, within limits

As custodian, you can spend custodial money on things that benefit your child, as long as you leave out what you already owe as a parent. Courts look closely at who actually benefits. In Wagman v. Wagman, a New York judge let a mother reimburse herself $1,546 from her son’s custodial accounts for a computer because it was clearly bought for him and he still used it, even though she had used it on a limited basis too. The internet service they shared was another matter: she could claim only half.

Timing matters as well. In In re Gumpher, a Pennsylvania court refused to let a custodian take reimbursement years later for a car, braces, and a class trip. The safest habit is to pay straight from the account when you buy, and keep the receipt. The Ultimate Guide to Legalities for Custodial Accounts covers more of these rulings.

For a life start, that means whatever you buy should be clearly your child’s: a car they drive, or a home they own and live in. A shared family car, or a house in your name as in Werner, invites exactly the kind of dispute that ended up in court there.

After the hand-off, your child decides

Once the custodianship ends, the decision is your child’s alone. A beneficiary who reaches the termination age is entitled to receive the unexpended balance of the account, as a New York appeals court put it in Mounsey v. Mounsey. Your child can spend it on a car, a wedding, a down payment, or nothing at all, and you can’t take it back. What Happens at the Age of Majority? lists the termination ages state by state.

That doesn’t leave you without a role. You become an adviser instead of a decision-maker, which is why the groundwork in The Hand-Off matters so much: a one-page plan written together before the transfer, a habit of leaving money invested until it has a job, and later gifts kept in your own name. If your account’s termination age is 25, you’ll still be the custodian through the first years after college, when a first car or apartment often comes up.

Put the two timelines side by side, and the gap is plain.

• A common hand-off age
• A median milestone age

Each square marks an age, either one at which custodial accounts commonly change hands or the median age for each milestone. The marriage ages are the Census Bureau’s estimates for 2025, and the home age comes from NAR’s survey of people who bought between July 2024 and June 2025.

Which accounts can pay for what

Custodial accounts aren’t the only place a family’s savings sit by the early 20s, and each account has its own rules for a car, a wedding, or a home:

A 529 plan is built for education. A withdrawal for anything else will probably face taxes and a 10% penalty on the earnings, Saving for College notes, so it’s the wrong pot for a car or a wedding. Leftover 529 money has better exits: another family member’s education, or a rollover into your child’s Roth IRA within limits, as The SECURE 2.0 Act explains. The Complete Guide to 529 College Savings Plans covers the rest, and if your child is still young, Setting Realistic Goals shows how to split savings between college and the life starts that come after it.

Retirement accounts have a narrow door for a first home. Your child can take out what they contributed to a Roth IRA at any time, tax- and penalty-free, and up to $10,000 of earnings over a lifetime can come out without the 10% penalty for a first-time home purchase, according to Schwab. For this rule, a first-time buyer is anyone who hasn’t owned a home for the past two years, and the earnings come out tax-free too if the account passes the five-year test, Kiplinger explains. The Custodial Roth IRA covers how a summer job can start one.

A Trump Account opens later. Its growth period ends before January 1 of the year your child turns 18, and after that it generally follows the rules for traditional IRAs, under IRS Notice 2025-68. Those rules let up to $10,000 over a lifetime go toward a first home without the 10% penalty, Kiplinger notes, though any taxable part of the withdrawal is still taxed. The 530A Trump Account Explained has the details.

Before you sell, plan the taxes

Most custodial accounts hold stocks or funds, so turning one into a car or a down payment means selling, and selling can mean tax. The tax is your child’s, because the account is in their name, though the kiddie tax can pull in your rate while they’re young. Three rules keep the bill small. Liquidating Safely walks through the paperwork.

Hold for more than a year, and use losses

Gains on investments held more than one year are long-term, while gains on those held a year or less are short-term and taxed as ordinary income, according to IRS Topic 409. Long-term rates are lower, so check the purchase dates before selling anything bought recently. If some holdings are worth less than they cost, selling them too can offset the gains, and up to $3,000 of net loss a year can reduce other income, with the rest carried forward.

Use low-income years

In 2026, long-term gains are taxed at 0% for a single filer whose taxable income, gains included, is $49,450 or less, under the IRS’s inflation adjustments for 2026. Add the $16,100 standard deduction for a single filer, and a young adult with a modest salary, or a year between jobs, may be able to sell a good share of their gains at a 0% federal rate. The worked example under the first home below shows what that can save.

Watch the kiddie tax through 23

Before then, a low bracket can be an illusion. The kiddie tax can tax a child’s investment income above $2,700 at the parents’ rate, and it can apply to a full-time student through age 23 whose earned income doesn’t cover more than half of their own support, under the IRS’s Form 8615 instructions. Big sales usually go further once your child is out of school or supporting themselves. Navigating the 2026 Kiddie Tax Thresholds has the numbers.

A first car

A car is the one life start that often arrives before the hand-off, for getting to a job, an internship, or a campus across the state. That makes it the one where you’re most likely to be the decision-maker.

If you’re still the custodian

A reliable car for your child can be a fair use of custodial money, but no rule spells it out. Writing about Werner, Ashton listed buying a minor a car among the questions on which the appellate cases seem to provide little guidance. Courts ask who benefits, as the Wagman computer ruling shows, so make the car clearly your child’s:

• Your child is the main driver, and the car is titled in their name where your state allows it.
• You pay the seller straight from the account at the time of purchase, rather than paying yourself back later.
• You keep the bill of sale with the account’s records.
• You leave out costs you’d owe anyway as a parent.

If the money is already your child’s

After the hand-off, your child chooses, and the strongest case is for paying cash. In the second quarter of 2026, the average used-car loan was $27,852 at an average rate of 11.19%, according to Experian data reported by Auto Remarketing. At that rate, a five-year loan for that amount would cost about $8,600 in interest. Paying 11.19% to keep money invested at a hypothetical 7%, the return assumed throughout GoodNest’s guides, is a losing trade.

A loan can also slow the next goal. In NAR’s 2025 survey, first-time home buyers named car loans among the debts that held them back from saving. A reliable used car bought with cash, with enough left for emergencies and the rest still invested, keeps the bigger starts within reach.

A wedding

The average wedding cost $34,200 for couples married in 2025, with 117 guests at $292 per guest, according to The Knot’s 2026 Real Weddings Study, which surveyed 10,474 couples. With the median first marriage at 28.4 for women and 30.8 for men, the account has usually changed hands by then, so how much of it goes to the wedding is your child’s call, and their partner’s.

Your part is to help them see the trade. At a hypothetical 7% average annual return, $34,200 spent at 30 could have grown to about $365,100 by 65. That’s not an argument against a wedding. It’s the number to weigh it against, the same way you’d weigh a down payment or paying off a loan. One approach that keeps the trade in view is to set a fixed amount for the wedding first, then plan the day around it.

If you’re helping pay for it

Money you give toward the wedding comes from your own savings, so it’s a gift. Paying for a child’s wedding or honeymoon counts as a gift for tax purposes, Empower notes, and paying the venue directly doesn’t change that: the IRS’s special exclusions for paying someone else’s bills cover only tuition or medical expenses, according to its gift tax FAQ. In 2026, each parent can give $19,000 to your child and another $19,000 to your child’s spouse or partner without filing a gift tax return. Above that, you file Form 709, but tax is rarely due, because the excess counts against a lifetime exemption of $15 million per person in 2026. The Impact of the 2026 Gift Tax Exclusion covers the details.

A first home

A first home is the life start where custodial savings can do the most, because the money buys an asset that can build equity rather than a day or a car that loses value. It’s also the hardest to reach. First-time buyers fell to 21% of home purchases in NAR’s 2025 survey, the lowest share since it began tracking in 1981. Among them, the median down payment was 10%, matching the highest level since 1989, Builder reported, and 59% used savings while 26% tapped financial assets.

That last number is the opening for a family that has saved. For the first time, NAR found, first-time buyers were more likely to use financial assets than help from friends or family for their down payment. A former custodial account is exactly that kind of asset.

Make sure it’s your child’s home

If you’re still the custodian when your child buys, Werner is the warning. The home has to be your child’s, in their name and theirs to live in, not a family home in yours. Once the account has changed hands, it’s simply your child’s money, and your role is to help them plan.

Move the money to cash early

Money for a down payment shouldn’t ride the stock market in its last few years. Large-company stocks as a group have lost money in about one of every three years, on average, the SEC’s Investor.gov notes, and keeping money entirely in cash investments, such as savings deposits, CDs, Treasury bills, or money market funds, may be appropriate for short-term goals. Shift the down payment out of stocks on a schedule, the way Building a Target-Date Glide Path does for college, so a bad year right before closing can’t shrink it.

Spread big sales over two tax years

Selling over two calendar years can keep more of the gain in the 0% band. Suppose your daughter, 28 and single, earns $55,000 a year and plans to put $40,000 from her former custodial account toward a first home: $20,000 that went in over the years and $20,000 of long-term gains. That’s 10% down on a $400,000 home, the median first-time buyer’s share. Here’s the federal tax on her gains under 2026 rules:

Selling it all in 2026 would cost $1,418 in federal tax. Selling half in 2026 and half in early 2027 would cost nothing for 2026, and the second half would land in the 0% band too if her income and the thresholds stayed about the same. The example assumes she takes the standard deduction and has no other income, and it leaves out state income tax, which can still apply. Since the money is headed to cash anyway, selling in two steps fits the schedule.

Have the paperwork ready

Lenders want to see where a down payment comes from. Under Fannie Mae’s rules for the conventional mortgages it buys, stocks and mutual funds can count toward a down payment if their value can be verified, and if the account is worth at least 20% more than the cash needed for the down payment and closing costs, no proof of the sale is required, according to its Selling Guide. Otherwise, the lender needs evidence that the borrower actually received the money from the sale. Selling early and keeping every statement makes this easy.

If you add a gift of your own, expect the lender to ask for a gift letter. For a one-unit primary home, Fannie Mae allows gift money from an acceptable donor, such as a relative, with no minimum contribution from the buyer’s own money, as long as the donor signs a letter that states the amount and that no repayment is expected, under its gift rules.

Five questions before any withdrawal

Whether you’re the custodian or the adviser, the same five questions help with any life start. They work best asked well before the money is needed, as part of the talk in The “Wealth Transfer” Conversation.

• Is there a cushion left? A withdrawal should leave an emergency fund in place, so the next surprise doesn’t land on a credit card.
• Will it hold its value? A home can build equity, a car loses value, and a wedding is a day. All three can be worth it, but they aren’t the same kind of spending.
• Is there cheaper money? Borrowing at a rate below what the money might earn can make sense. Borrowing above it, like the average used-car loan, usually doesn’t.
• What will it cost at 65? The table below shows what $10,000 could grow to if it stayed invested instead.
• Is it in the plan? A purchase that matches the plan you made together is easy to say yes to. A big one that doesn’t is worth a second look.

The figures use a hypothetical 7% average annual return. Every $10,000 spent at 22 could mean about $183,400 less at 65, and spent at 40, about $54,300 less. The later the spending, the smaller its long-run cost.

Helping from your own savings

Money in your own name is the one pot you control at every age, which makes it the right place for help you want to time yourself. Custodial Brokerage Accounts vs. Parent-Owned Taxable Accounts compares the trade-offs. A few rules shape how to give it:

• Annual limits. Each parent can give $19,000 to each person in 2026 without a gift tax return, and larger gifts usually mean paperwork, not tax.
• Shares or cash. When you give shares instead of cash, your child takes over your cost basis. In the IRS’s example, stock bought for $10 a share and sold for $100 leaves a $90 gain on each share. If your child is past the kiddie tax and in a lower bracket, letting them sell can cost less tax than selling yourself.
• Your own security first. Help that drains your retirement savings can become your child’s problem later, as The “Oxygen Mask” Rule of Parental Finance explains.
• Structure, if you want it. If you want a say in how future gifts are used, a trust can hold the money and pay it out on terms you set, as Understanding Trust Funds for the Middle Class explains.

Share the milestone with the people who gave

GoodNest is built for the years of gathering that make these life starts possible. You create a page for your child and share one link with the people you choose, and the same page can stay with your child from the shower to graduation. Guests can give without creating an account, and the page keeps each gift with the giver’s name and note. GoodNest doesn’t hold or invest the money. Gifts go straight to you by Zelle, Venmo, or PayPal, and you move each gift into the account it’s meant for.

Years later, those names and notes turn a purchase into a story. When the savings become a first car or the keys to a first home, your child can tell the people who gave, birthday by birthday, what their gifts became. A short note or a photo of the new place makes a better thank-you than any statement, and a GoodNest postcard, a few words and up to four photos, reaches only the people who gave. Thank You Notes and Portfolio Updates shows how to estimate how much each giver’s gifts have grown, and Building Your Village covers the bigger picture.

Your life-start checklist

Before any custodial money becomes a car, a wedding, or a home, aim to check off each of these:

• The termination age, confirmed. You know when the account changes hands from the firm that holds it, not from memory.
• Clear ownership. Anything custodial money buys before the hand-off is your child’s, used by them and titled to them.
• Direct payment and receipts. Purchases come straight from the account at the time, with the paperwork saved.
• A tax plan for the sale. You know which holdings have gains, whether the kiddie tax applies, and whether splitting the sale across two years helps.
• Short-term money in cash. Anything needed within a few years, like a down payment, is out of stocks.
• A cushion left over. Each withdrawal leaves an emergency fund in place.
• Lender paperwork. Statements are saved, and any gift from you comes with a signed gift letter.
• Your gifts within your limits. Help you give fits the $19,000 exclusion or goes on a Form 709, and it doesn’t come out of your retirement.
• A thank-you. The people whose gifts made the life start possible hear what their money became.

The bottom line

Custodial money can give your child a running start on a car, a wedding, or a first home, as long as what it buys is truly theirs and the decision sits with whoever controls the account at the time. Before the hand-off, that’s you, within the rule Werner made plain. After it, it’s your child, and your influence comes from the plan you made together, the tax and timing know-how you share, and the help you keep in your own name. The Hand-Off: Safely Withdrawing and Transitioning Wealth covers the rest of this final phase, and The “Wealth Transfer” Conversation has the script for talking it through.

Frequently asked questions

Can I use my child’s UTMA account to buy them a car?

Yes, if you’re still the custodian and the car is truly for your child: they’re the main driver, it’s titled to them where your state allows, and you pay straight from the account at the time of purchase. A shared family car is harder to defend. After the termination age, the money is your child’s, and the choice is theirs.

Can custodial account money pay for a wedding?

It can, but by the typical wedding the choice is rarely yours. The median age at first marriage was 28.4 for women and 30.8 for men in 2025, past most termination ages, so the account usually belongs to your child by then. Help you give from your own savings counts as a gift, even if you pay the vendors directly.

Can a UTMA account be used for a down payment on a house?

Yes. Once the account has changed hands, your child can use it like any other savings, and lenders following Fannie Mae’s rules accept stocks and mutual funds whose value can be verified. If you’re still the custodian, the home must be your child’s. In Werner v. Werner, the courts sent all the proceeds from a house a Pennsylvania mother bought with her children’s custodial money back to their accounts.

Do you pay taxes when you sell investments in a custodial account?

Yes, on any gains, and the tax is your child’s because the account is in their name. Gains on investments held more than a year get lower long-term rates, which are 0% in 2026 for a single filer with taxable income of $49,450 or less. The kiddie tax can tax a full-time student’s investment income above $2,700 at the parents’ rate through age 23.

Is there gift tax if I help my adult child buy a house or pay for a wedding?

Rarely. In 2026, each parent can give $19,000 to each person, including your child’s spouse or partner, without filing a gift tax return. Larger gifts go on Form 709 and count against a lifetime exemption of $15 million per person, so tax is seldom due. For a home, the lender will usually also want a signed gift letter.
