In any part of the world that I know of, it would be impossible to adopt a child at that age. It is well below the lower limit of adoption and there are other factors that are considered that would be difficult for a fifteen year old to fulfill. The input of your parents does not count unless they are the ones applying to adopt for themselves.
highly doubt it you need to be an adult to adopt
If you are their legal guardian, you can collect child support from both parents of the child. If you are not their legal guardian and they just live with you, you do not have rights to child support.
No, as the payor has to approve the adoption
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.
child support is used for parents who are divorced and have legal custody of the child, so the parent gets money from his/her spouse to help support and raise the child
Earliest should be at around 15; before 15 the child is too immature and very easily influenced.
In the United States: Mother- It's your choice if you want to keep the child or not. Your parents, friends, or boyfriend can't choose for you. Remember while making the choice is that it's your parents right to say that they are not going to help\take care of the child for you. Unless your parents agree to help\take the child, and you decide to keep it, your on your "own" with it. Father- It's the mother's choice on whether the baby stays or goes. I'm not sure if you have to pay child support at your age, but once you are 18 you will if asked for it.
Generally no; you must be self sufficient with ample life experience to properly nurture a child in order to be allowed to adopt. speculation: in some jurisdictions it may be possible to do a step parent adoption at 17.
The parents of the child.
They certainly can. The parents can determine where a child lives. It does not relieve them of responsibility for their child.
The parents will have to make some kind of living arrangement for the child because a 15 year old is a minor, just to abandon a child of this age is against the law. When the circumstances warrant that the child should be removed the Social Services will have to step in.
No, only the parents decide this and the adoption papers is the only legally binding contract a minor can sign. When it comes to your child you have the same rights as an adult. No one can force you to keep the child, abort or give it up for adoption.
