What parenting plan means
A parenting plan is the document that sets out how co-parenting will actually work: the custody schedule, holiday and vacation arrangements, how and where exchanges happen, how major decisions are made, and often how shared expenses are divided. In many jurisdictions a parenting plan is required in every custody case and, once approved, becomes an enforceable order.
The plan is the baseline everything else gets measured against. Documentation only means something in relation to what the plan requires: a late exchange matters because the plan set a time; a denied weekend matters because the plan granted it. Knowing your plan in detail is what lets you document deviations precisely.
Example: if your plan says holidays alternate by year, logging that the other parent kept the child over a holiday that was yours this year is a clear, specific deviation, not a vague grievance.
Parenting plans and their required contents vary by state, so read yours closely and let your attorney explain any terms whose meaning is not obvious.
