Age of Majority on your state
Whether the grandparents have access to their grandchild or in this case step grandchild, is entirely up to the parents. They decide who will have access to the child and they might favor someone who is not a blood relative. Step grandparents can be just as good as blood related ones.
The child himself can not decide whether he should be adopted or not, only his guardians or the court decide this.
If you mean can your parents force you to do it, then yes, they can.
A child is not allowed to choose who to live with, that is up to the parents or the court to decide. In some states the child can say what they wish but the judge is in no way obligated to follow that wish. And the relative have to let the parents know they are interested so the parents can go to court and have custody changed and decide on how much child support is going to be paid to the relative. So unless you are abused by your parents, in that case contact the Child Protective Agency, your parents are the ones deciding for you and they are the ones you should turn to. In case of abuse the social workers will ask relatives if they are interested and if they are, they have to petition the court for custody or foster care.
You used the word child. And legally they are a child and the parents decide where they are to live.
Yes, you can rent an apartment at age 16, but you cannot claim child support from your own parents, whether they are together or separated.
Is that between a child's parents? if so it is ultimately up to the parents. But, most parents will let the child decide who they want to live with.
wait till child is old enough to decide for themselves
As long as you are a minor you can not decide legally where to live.
{| |- | Parents don't decide whether a child can be emancipated or not. In some states the parents have to sign the paperwork, but the court will make the decision. The parents do get to state their case and the courts are usually going to support that position. The parents are responsible for a minor until they are adults and the court isn't going to want to risk the child becoming a ward of the state. |}
If the child was adopted for real there should be papers signed by birth- and adoptive parents. The birth certificate is sometimes changed by the adoptive parents but not always. If the child was just handed to a relative and nothing was singed or they did not go to court for child support or there was no temporary custody signed, it gets trickier. Eye witnesses and people around could testify.
Yes ... all personal effects are returned to the parents or next living relative.
