Synopsis As Introduced Amends the Illinois Marriage and Dissolution of Marriage Act. Establishes a rebuttable presumption that joint legal and physical custody is in the best interest of the child. If both parents are fit but joint legal and physical custody is not feasible and cannot be remedied by a Joint Parenting Agreement between the parents, establishes a rebuttable presumption that it is in the best interests of the child to grant legal and physical custody to the parent more disposed to encourage and permit frequent and continuing contact by the other parent with the child. Requires the court to justify any departure from either presumption with detailed findings. Deletes language providing: that there shall be no presumption in favor of or against joint custody; and that the court may enter an order of joint custody if it determines that joint custody is in the best interests of the child, taking certain factors into account.
