I'm pretty sure that most Hunters are officially-sanctioned super-vigilantes. They have a license to enforce the law as well as kill Grimm on sight.

I also suspect that Sun and Penny are both representatives of a 'renegade' type of Hunter who doesn't think they need a signed form from City Hall (or, in their particular cases, are not eligible for said signed form due to legal or species issues) so just do it anyway.
