This is a post-divorce child custody action involving two children, who were sixteen and seventeen years of age at the time of the most recent trial. The parties were divorced by order of the Sullivan County Law Court ("divorce court") in July 2001.

The 2015 PPP maintained the father's designation as the primary residential parent and provided the mother with 85 days of residential co-parenting time, a great part of which was to be exercised at her residence in Texas. On October 2, 2015, the mother filed an "e
