Should I take my daughter (7 year old) with to court? (Adoption)?

there will be 2 separate court hearings. One, terminating the other parents rights, which a child has Absolutely no place at, and a few weeks later for the adoption hearing. Which is something definitely to bring her to. That's a big celebration event in all your lives !! The agency that did your adoption home study should have explained this all to you. (all adoptions in the US require adoption home studies by a licensed agency)
