Is he breaking under aged magic laws?

I'm going to say that he can attempt the spell, but trying at this stage subverting m something would go wrong. Just like those who tried to use magic in the train fight.

No, his father taught him with sticks and shit. Y'know, to practice, so some of the spells, he could attempt and make first try.

Everte Statum on the other hand, is quite an advanced spell, so I think I'll stick with explelliarmus or something.
