Can an allocation of parental rights and responsibilities be modified?
The court shall not modify a prior decree allocating parental rights and responsibilities for the care of children unless it finds, based on facts that have arisen since the prior decree or that were unknown to the court at the time of the prior decree, that a change has occurred in the circumstances of the child, his/her residential parent, or either of the parents subject to a shared parenting decree, and that the modification is necessary to serve the best interest of the child.
