Do I need a separate consent form for minors?
Minor consent is one of the areas where a generic answer is not a safe answer. States differ on whether a minor can be tattooed or pierced with parental consent at all, what age that applies from, whether a parent must be physically present, and what documentation is required. Some states do not allow it under any consent.
Because of that spread, do not rely on general advice here, including this article. Check the specific rule with your state board or licensing authority before you tattoo or pierce anyone under 18, and keep whatever documentation your state requires on file.
Turbo Link's consent and release forms are signed on a phone as part of the booking flow, which makes it easy to keep a signed record on file, but the shop is responsible for confirming what that record needs to include for a minor in your state.
