Father seeks joint legal and physical custody. In addition, 24 Father requests the children attend school in Maine starting the 2026-2027 school year.

Father 25 requests he be the “school parent” and Mother be the “summer and school break parent.” Father 26 indicates their daughter expressed an interest in attending school in Maine and requests a Tier II 27 interview of the minor children. 28 3) On May 19, 2026, Mother filed a Responsive Declaration in which she asks this Court to deny 29 Father’s requests.

A violation of this order may subject the party in 12 violation to civil or criminal penalties, or both.
