What parenting time means
Parenting time, still called visitation in some places and older orders, is the schedule of time the child spends with each parent under the parenting plan or court order. Many jurisdictions have moved to the term parenting time deliberately, because it frames both parents as raising the child rather than one merely visiting.
Deviations from the schedule are the single most commonly documented category of custody events, and for good reason: late arrivals, missed time, denied time, and last-minute cancellations are concrete, datable, and directly tied to what the order requires. They are exactly the kind of pattern courts look at.
Example: an entry noting that scheduled Friday time was denied, with the date, the reason given, and any message about it, is far more useful than a general sense that the schedule is not being honored. Each specific instance is a data point; enough of them form a pattern.
Because the terminology and enforcement mechanisms vary by state, check what your own order calls the schedule and route questions about enforcement through your attorney.
