You can certainly go to the courthouse, but you most likely will not be allowed in the court room. My old state is the same, family court proceedings are considered private, and only the parents are allowed. Or the custodian - if that person is not a parent. Step-parents are not allowed. I don't know if my new state is the same, I'm hoping I don't find out anytime soon (meaning I hope I don't have to go back to court anytime soon).
