Summer was adopted by Drew Spellman after her real dad (Charlie, I think - he's never seen on the show) couldn't look after her for whatever reason. Drew used to go out with Billy I think and they stayed good friends after they stopped seeing each other. I think it was in 2017, Drew finds Billy again and tells him he's dying and asks if he'll look after Summer when he's gone. I think he wrote it in his will that he wanted Billy to look after Summer, so I believe Billy is her legal guardian.

Sort of, but there are rumours that Paul plans in adopting her, not sure how true they are

What does that have to do with this.
