It is the policy of the Osage Nation to assure that minor children have frequent and continuing contact with parents who have shown the ability to act in the best interests of their children and to encourage parents to share in the rights and responsibilities of rearing their children after the parents have separated or dissolved their marriage. To effectuate this policy, if requested by a parent, the Court shall provide substantially equal access to the minor children to both parents at a temporary order hearing, unless the Court finds that such shared parenting would be detrimental to such child. The burden of proof that such shared parenting would be detrimental to such child shall be upon the parent requesting sole custody and the reason for such determination shall be documented in the court record.
