Among divorced couples with children, it may happen that the non-custodial parent is concerned that the money paid for child support is not being spent with the best interests of the child in mind. Or, there may be concern that the custodial parent is not raising the child in a generally acceptable manner. The court does not usually involve itself in what may be regarded as family arguments regarding the upbringing of a child. The court will become involved, however, if it can be shown that the custodial parent's conduct is contrary to the best interests of the child. The burden of proof in such matters rests with the non-custodial parent.
