Most plans cover the schedule well. The recurring disputes almost always come from what the plan did not mention.
The regular schedule, holidays and school breaks, how decisions about health and education are made, and how the parents communicate.
The form and the requirements vary substantially by jurisdiction, and what a court will approve or order is not something a general description can tell you.
What happens when a parent cannot use their time. Whether the other gets first refusal before other childcare is arranged, and how much notice applies.
Travel: how far, with what notice, whether the other parent holds the passport, what happens for international trips.
Almost every recurring dispute traces to a situation the plan did not anticipate.
Introducing a new partner — whether there is any notice expectation, and at what point. This is a common flashpoint and is very rarely addressed in advance.
Communication with the child during the other parent's time. Frequency, method, whether it is scheduled.
Extracurricular activities that span both households, who pays, and who takes them.
The mechanism for adjusting the plan as children get older. Plans written for a five-year-old fit badly at fourteen, and without a process every adjustment becomes a negotiation from zero.
What happens when the parents disagree. Whether mediation comes first, and what the process is before anything escalates.
Agreed in advance it is a procedure. Agreed during a dispute it is another dispute.
No plan anticipates everything, and an extremely detailed plan can be its own problem — rigid, hard to operate, and a source of technical arguments about compliance.
The aim is covering the predictable and having a workable process for the rest.
