Depends on what state you are in. The minor can also ask for a judicial bypass. Call your local Planned Parenthood and ask.
Nothing can happen to the parents as long as the 19 year old and 15 year old are not having sex.
No unless the minor wants to press charges
The parents will continue be responsible for their daughter and for her child.
It depends on how the parents teaches his or her son or daughter.
I'm pretty sure that's illegal.
No. That is her fiance, because of their relationship he can not be her legal guardian.
i would geuss not anything that is legal.
No. They can keep their child from him but they have no right to keep him from his child.
The 17 year old must have permission from their parents to move in with this family. Otherwise the boyfriend's family could be charged with kidnapping, even if the daughter claims she wants to live there. Since the daughter is not yet 18, or an adult, her parents are still responsible for her.
Yes and the 19 year old can go to jail for that.
To date yes, but for sex the minor must have reached age of consent.
Legally, not really. The rule is there has to be two years difference between the two partners in a relationship to be romantically involved. sorry.
