If/when custody disagreements occur between parents concerning the custody and visitation order or discrepancies, mediation may be the way to reach a solution without the intervention of the courts. Mediation is meant to create a parenting plan that will best benefit the child/children while allowing your them to spend the most time possible with each parent as well as allow the parents to deal with the anger and frustration in a neutral environment.
If parents are able to work out the issues in mediation, then the mediator is able to also help draw in a new custody and visitation order covering the changes.
