The brand said yes. That's the hard part, and your kid just pulled it off.
Then the agreement arrives as a PDF. At the bottom there's one blank line, and under it is a sixteen-year-old's name.
Don't sign that page. Not because the deal is bad. Because that line is in the wrong place, and fixing it is a ten-minute job that decides who's on the hook for the next twelve months.

A 16-year-old's signature is a suggestion
In most of the United States, a person under 18 can't be held to a contract.
The agreement isn't automatically void. It's voidable. That means it stands until the minor decides to walk away from it, and the right to walk usually lasts until they turn 18 plus a reasonable period after that. If they keep taking the money once they're an adult, that counts as ratifying the deal and the escape hatch closes.
So your kid's signature is real in one sense and worth nothing in another. It's a promise. It isn't enforceable.
Any brand with a lawyer already knows this. It's exactly why nearly every state that opened high school NIL now requires a parent or guardian to sign off for athletes under 18.
Which lands the whole thing on you.
We already wrote the companion piece on the other stack of paper — racing waivers and team agreements for parents. This post is only about the sponsor deal, and specifically about whose name goes where.
The parent doesn't witness it. The parent owes it.
Here's the part families miss.
When you co-sign or guarantee, your obligation is its own thing. Published guidance on parent guarantees puts it plainly: the parent's obligation is separate from the minor's and can be enforced directly against the parent.
Read the deliverables again with that in mind. They're not your kid's chores. They're your contract.
Ten social posts a season is ten posts you owe. Two appearances is two appearances you owe. If your driver gets hurt, gets grounded, loses interest in October, or puts the car in the wall at Pueblo, the obligation doesn't disappear just because the season did.
The minor can walk away from the contract. The parent who guaranteed it cannot.
And this is getting sharper, not softer. Lawyers working the high school NIL space are now flagging parental indemnity language — clauses that let the brand come after the parent when the athlete stops delivering.
That's not a reason to say no. It's a reason to read the exit and the make-good terms before you sign, which we broke down in what happens when a season falls apart.
Youth sports already wrote the guardrails. Borrow them.
Motorsports has no rulebook for minors and money. Other youth sports just built one in public, and three pieces of it are worth stealing outright.
1. A written banned-category list. Louisiana's 2026 high school NIL law bars deals tied to adult entertainment, gambling, alcohol, tobacco, marijuana, and weapons. We keep our own version of that list, and it's basically the same: no alcohol, no tobacco or vaping or cannabis, no adult brands, nothing that would make a 14-year-old on our grid uncomfortable. Write yours down before the offer shows up, not after.
2. A dollar threshold that triggers a real review. One of the competing bills debated in Ohio would require a written contract, parental consent under 18, and disclosure and review of deals worth more than $500. You can adopt that at your kitchen table today. Under your number, sign it. Over your number, somebody qualified reads it first.
3. A trust split on the money. California's Coogan law requires 15 percent of a minor's gross earnings to be set aside in trust for them. That statute covers contracts where "a minor is employed or agrees to render services as a participant or player in a sport." Most states have nothing like it. Set your own 15 percent anyway.
California goes one step further, and it's the cleanest fix in the whole area of law. Under Family Code 6751, a contract of that type can't be disaffirmed — not during minority, not later — if a superior court approved it. Court approval is overkill for a $1,000 local deal. For a real one, it's the only way a brand gets certainty and your kid gets a reviewed contract at the same time.
The paperwork is boring. The thing it protects isn't.
What the signature page should actually look like
Three blocks, not one.
The driver signs. It doesn't bind them, and that's fine. It makes them read what they promised, and a kid who signed their own deliverables shows up differently on a Tuesday night when a post is due.
The parent or guardian signs as a named party. Not "witness." Not "parent." The page should say what you're signing for, in a sentence — that you're guaranteeing the driver's obligations under specific numbered sections.
The brand signs with a name and a title. Get the person who can approve the spend, not the intern running the inbox.
Then four mechanics that do the real work:
- Split the obligations line by line. Which items are the driver's, which are the parent's. Legal guidance on parent guarantees says the same thing: separate the two so you don't take on more than you meant to.
- If two parents share custody, get both signatures. This is the exact problem that turns families away at race registration. It will find you here too.
- Name the account the money lands in before there is any money. Whose name, which bank, what happens to it. Decide it in writing while everyone's happy.
- Say out loud who carries the disclosure. The FTC's endorsement rules require a clear and conspicuous disclosure whenever there's a material connection, and the Commission has been explicit that kids often can't tell when someone's being paid. If the parent runs the account, the parent owns the "#ad."
If you want the actual documents — the agreement, the media kit, the outreach emails, and the parent-facing chapter for exactly this situation — that's what's inside The First Sponsor System. It's $67 and it's the paperwork we use to fund our own Spec Miatas.
None of this is legal advice. State law varies, and if the number on the page is big enough to matter to your family, pay a lawyer for an hour.
How to pitch at 16 without getting treated as a risk
The age isn't the problem. The uncertainty is.
A marketing manager who likes your kid still has to answer one question internally: who signs this and who's accountable? Answer it before they ask.
- Name the signer in the first email. One line does it: "I'm 16, my mom co-signs everything and she's copied here." You just removed the objection nobody says out loud.
- Run one thread, one inbox. Not a text chain with the kid and a separate email with the parent.
- Only promise what an adult can guarantee. Rides to the activation, the recap email, the photo delivery. Those are the deliverables that survive a bad race weekend.
- Lead with the age, don't hide it. A 16-year-old racing Spec Miatas against adults is the most interesting thing in the pitch. What sponsors actually want from a karting family goes deeper on that angle.
Our own grid runs on this. Kart to Car is built for drivers 13 to 25, so most of the sponsorship conversations we sit in on have a parent in the room. The families who get deals aren't the ones with the fastest kid. They're the ones who show up organized.
And if you're holding a real offer right now and the signature page is making your stomach hurt, don't guess. Proposal Review is $147 — you send us what you're about to sign or send, and you get it back marked up in writing.
Before that, get the documents right. The First Sponsor System is $67 and it's everything we hand a young driver's family on day one: the agreement structure, the pitch, the media kit, and the reporting that makes a brand renew. One correct signature page is worth more than ten good intentions.
Your kid can't sign it. You can. Do it with your eyes open.
