These are the laws governing the state of Indiana.
There are two kinds of custody: physical and legal. Physical custody determines where a child lives, whereas legal custody determines who makes major decisions regarding how the child is raised. Physical custody can be shared or one parent may have primary physical custody while the other parent has visitation. Likewise, legal custody may be handled jointly or one parent may have sole legal custody. .
Custody can be modified if such a modification is in the child's best interest or if there has been a substantial change to the circumstances that determine custody.
