Let’s say your Court order says that Parent A is to have parenting time with the children from Thursday until Sunday every other week. You and Parent A disagree about what week is “every other week” and cannot agree on when parenting time begins and ends. If a PTE is appointed in your case, the PTE can work with the two parents to construct a more specific schedule for parenting time, or, if agreement is not possible, the PTE decides which weeks parenting time will occur and what time it begins and ends.
