Yes, as long as they are no longer minors.
Any child can be cut out of a will by the testator. There is no obligation for a parent to leave anything to an adult child. The court will insure that minor children are looked after. By law, an adopted child is the same as a natural child.
Not without permission of the parent with legal custody. Or they will need a court order.
The parent may leave a child out of their will. If they are a minor, the court may include them so the state doesn't have to pay for their support.
A pregnant minor or one who is already a parent is not emancipated apart from regarding their health or the child. And adopted children are legally like the biological ones to the adoptive parent. This means you are not emancipated until you are 18 and can only then decide where to go or move.
Here you will have to go to court and let the judge decide with who you should stay with, after asking you in court in private. You just can not decide on your own as it wont be binding like the one in court.
Yes, and ground for contempt of court with a change of custody.
The 18 year old is an adult and can leave, but if it is a court session the court will charge them and may arrest them.
A minor cannot leave the home of the custodial parent without that parent's permission. The noncustodial parent can petition the court for custody rights pertaining to the minor child. Depending on the child's age the court will take into consideration the opinion/feelings of the child before rendering a decision.
A noncustodial parent can prevent the custodial parent from leaving the state with a baby or child. The court will decide if the custodial parent has just cause to leave the state.
Only if she is emancipated or there is a court order. Social services can provide assistance on how to get help.
This depends on the state, and is no different than any other child (unless there is specifically a court order in your case that says otherwise)
Not if the court has declared one the custodial parent. Until they reach adulthood, normally 18, they live where they are told to.
