Mo. Rev. Stat. § 452.404: Neutral location for exchange of children, when.

To ensure compliance with the parenting plans or court orders, the court may require parents, or parents may agree, to bring the minor children to a neutral location for the exchange pursuant to such plans or orders. Such location may include a center specifically established for such exchanges or an existing location suitable for such exchanges. A neutral third party may be present at each exchange to provide an accurate documentation of the compliance or noncompliance with the ordered exchange.
