Sole custody means that only one person, usually a parent, is legally responsible for taking care of their child. This means that the parent who has sole custody has the right to make decisions for their child and to be the one who takes care of them on a daily basis. This includes making decisions about where the child lives, where they go to school, what healthcare they receive, and other important matters. In some cases, the other parent may still be allowed to visit the child, but they do not have legal permission to make decisions for them. Sole custody is often given when the other parent is unable or unwilling to take care of their child or if it is in the child's best interest.
