Mo. Rev. Stat. § 452.1238: Nature of authority created by temporary custody order.

1. A grant of authority under sections 452.1224 to 452.1244 is temporary and terminates under sections 452.1246 to 452.1252 after the return from deployment of the deploying parent, unless the grant has been terminated before that time by court order. The grant does not create an independent, continuing right to caretaking authority, decision-making authority, or limited contact in an individual to whom it is granted.

2. A nonparent granted caretaking authority, decision-making authority, or limited contact under sections 452.1224 to 452.1244 has standing to enforce the grant until it is terminated by court order or under sections 452.1246 to 452.1252.
