Should You Modify Your Custody Order, Enforce It, or Both?
Quick answer
When a co-parent repeatedly violates a custody order, you generally have two separate legal paths: enforcement of the current order, or modification to change it. Many parents pursue both at once, and understanding the difference helps you decide where to start.

Enforcement vs. modification: two different questions
Enforcement asks the court to make the other parent follow the order that already exists. Courts can order make-up parenting time, impose consequences for violations, and in some cases award attorney fees to the parent who had to bring the motion. Enforcement does not change the schedule itself, it just puts teeth behind it.
Modification asks the court to change the order because circumstances have changed since it was entered. Most states require a meaningful change in circumstances before revisiting custody, and courts then decide based on the children's best interests. A pattern of one parent blocking parenting time, or a parent's declining ability to consistently care for the children, are the kinds of facts courts often consider relevant. The two requests are not mutually exclusive, and filing them together is common when violations are ongoing.
What evidence actually matters
Courts respond to patterns, not one-off incidents. A dated log of every denied, shortened, or changed exchange, kept as it happens, carries far more weight than a summary written from memory months later. Save the underlying communications too: texts, emails, and co-parenting app messages showing what was agreed and what actually happened.
Keep the record factual and child-focused. Notes like 'scheduled pickup 5:00 pm, told at 4:40 the kids were unavailable' are useful. Editorializing about the other parent's character is not, and can hurt you. If your concern involves the other parent's health or capacity, what matters legally is the effect on the children (missed school, missed medical appointments, unsafe situations), not the diagnosis itself. Stick to documented, observable facts.
How child support fits in
Child support in most states is driven by a guideline formula based primarily on each parent's income and the number of overnights each parent has with the children. That means custody and support are linked: if your parenting time increases significantly, the support calculation usually changes too.
Because of that link, many parents resolve the schedule first, or address both in the same case. If support is already unaffordable, ask whether your state allows a support modification based on changed income or changed parenting time. Running the numbers under a few different schedules before you file helps you understand what is realistic and keeps expectations grounded.
Proposing a schedule the court can actually order
Judges are more receptive to a parent who arrives with a specific, workable plan than one who simply asks for 'more time.' Map out exactly what you are proposing: which days, which exchanges, how holidays rotate, and how it works around school and work schedules for children of different ages.
Common structures include 2-2-3, 2-2-5-5, week-on/week-off, and 60/40 splits. Seeing the actual calendar also tells you how many overnights each parent would have, which feeds directly into the support calculation. Whatever you propose, be able to show the court that you can follow it consistently, since reliability is often the strongest argument a parent seeking more time can make.
