How is a parenting plan determined?

In general, all child custody decisions are to be based on “the best interests of the children.” The court looks at a number of factors including: limitations of a parent due to prior conduct or an impairment; agreements of the parties; the relative strength, nature and stability of child and relationship with each child; each parents past and future performance of parenting functions; the needs and developmental level of the children; and relationship with siblings and other folks.
