In general, there are two types of child custody - physical and legal custody. Physical custody refers to the child's placement, meaning, it determines with whom the child lives full-time and who is responsible for the everyday care of the child. Legal custody is concerned with the parent's right to make major life decisions related to the child's education, moving, religious upbringing, medical treatment, and so on.
Both of these types of custody arrangements may be either sole or joint (shared between the parents). Wisconsin Law typically welcomes joint custody unless it is proven that close contact with both parents is not in the child's best interest or if both parents agree on sole custody.
