Piercings & tatoos ... & maybe a little marriage

[Mom1Step2]

Just curious...
(facts: Florida, child is 16 & female)
Pretty sure I know the answer, I just wanted to know if anyone had any experience.
With joint legal, can either parent sign the waiver to allow a minor to get a piercing/tatoo? From all that I can find, it looks like only one parent needs to sign. Sure it may be possible to say after the fact... "You can't do that!". The problem is... the hole or tat is already there.
Another question... along the same lines... From what I can find, it requires both parents (unless one is dead, or the parent can prove they are sole) to sign for underage marriage. Of course if the one parent somehow pushes it through, the other parent can probably get it annulled. Anyone have experience with this one?
Man it's fun being the parents of teenagers!

We are from NY but came to Fla for vacation with my sister-in-law and her kids. She signed for her son to have tatoo in Florida. Needed one signature. (She is divorced).
Not much you can do once it is there.

Now the wedding one...not sure but here in NY, any marriage stops child support.
