Is a parent signature legally required on NIL deals for minors?

As a practical matter yes — minors' contracts are generally voidable without one, and many state rules and school policies explicitly require parental consent.

Does co-signing make the parent responsible?

It can — depending on the contract's terms, a co-signing parent may take on obligations if the deal goes sideways. Read before signing, and get a review for anything substantial.

Can an 18-year-old high school athlete sign alone?

Legally yes in most states, since they're an adult — but school and state athletic-association rules still apply to the deal itself.

Do Parents Have to Co-Sign NIL Deals for Minors?

Verified as of August 2026

Generally yes — and it's not just a formality. Contract law, not NIL rules, is what puts parents in the loop for athletes under 18, and a parent's signature carries real responsibility.

Why minors' contracts need a parent

In most states, contracts signed by minors are voidable — the minor can generally walk away, which makes companies unwilling to rely on a minor's signature alone. A parent or legal guardian co-signature is how brands make the deal enforceable. Some state NIL rules and many school policies also explicitly require parental consent for NIL activity by minors.

What co-signing actually means

You may be taking on obligations — depending on the contract, a co-signing parent can be personally responsible if the athlete doesn't deliver.
You're the quality gate. The co-sign requirement exists so an adult reads the deal. Use it: check the compensation, the rights granted, exclusivity, and how the deal ends.
You can involve a professional. For anything beyond trivial value, a one-hour contract review by a licensed attorney is cheap insurance.

What to check before you sign

Does the deal comply with your state's high school rules (no school marks, no prohibited categories)?
Is compensation specific — amount, dates, method — rather than "exposure" or "up to" language?
How long do the rights last, and can you exit?
Who handles taxes? (Spoiler: you do.)
