When Your Ex Breaches a Child Arrangement Order: Your Options

You have an order, and it is being ignored. That is one of the most frustrating places a parent can be, because the court has already decided what should happen and it is still not happening.

The remedy is a process, not a confrontation. This guide sets out what actually counts as a breach, the four things you can ask a court to do about it, what each costs, the evidence that matters, and the mistakes that hand the other side an advantage.

First: is it actually a breach?

A child arrangement order sets out where a child lives and when they spend time with the other parent. It binds both parents, and it usually carries a warning notice spelling out what can happen if it is not followed.

Day-to-day changes are not automatically breaches. If both parents agree to swap a weekend, that is a variation in practice. It is just worth remembering two things: it is not legally binding, and if the goodwill runs out the original order is what stands. A great many disputes start with an informal arrangement that one parent later relied on.

What a court will treat as non-compliance usually looks like this:

• Not turning up for handover, or arriving hours late, repeatedly.
• Returning the child early or late without agreement.
• Cancelling contact at short notice, or on thin grounds, as a pattern.
• Refusing to let the child go at the agreed time, with no reason given.
• Arranging activities, appointments or trips that make the ordered time impossible.

The word that decides most applications is reasonable excuse. The court will not make an enforcement order if it is satisfied the parent had one. Genuine illness, a real emergency, or a safety concern raised properly can all qualify. That cuts both ways: your ex may claim one, so a contemporaneous, dated record of what actually happened is the difference between a court believing you and a court being unable to tell.

The four things you can ask a court to do

There is a fifth, quieter option that resolves more cases than any of these: make the order more specific. A great deal of non-compliance happens in the gap between what an order says and what it does not. If the order says contact on alternate weekends but never says which Friday, at what time, at whose door, then every handover becomes a negotiation. Going back once to fix the detail is often more effective than going back repeatedly to complain.

What it costs

The court fee for an enforcement application is the standard children fee — two hundred and seventy pounds since the July 2026 fee change. Help with Fees is available on a low income, using form EX160, and it is worth applying rather than assuming you will not qualify.

Legal aid for private children disputes is limited, but it is available in cases involving domestic abuse where there is the right kind of evidence. If that applies to you, ask a solicitor specifically about legal aid rather than assuming it is out of reach.

Two questions are worth asking before you file anything:

• Is a mediation appointment required first? The rules are different for enforcement applications than for a fresh application about a child, so check what applies to your case rather than assuming. Mediation is often quicker and cheaper than a hearing, and a mediated fix is more likely to stick.
• What is your realistic outcome? If the breach is a single missed weekend after a year of compliance, a court is unlikely to be impressed. If it is the sixth cancellation in three months, that pattern is exactly what the court is there for.

The evidence that actually matters

Courts decide on clarity, not on how strongly you feel. A folder of four hundred screenshots proves nothing except that you kept screenshots. What works is a short, dated, factual log:

• The order itself, sealed and complete, including any warning notice.
• A chronological list: date, what was agreed, what happened, what was said, who was there.
• Messages showing what was arranged and what was cancelled — kept in context, not clipped.
• Handover records, including time of arrival and who was present.
• Any financial loss, with receipts.

Keep the log factual. Write down what happened, not what you think it means. The value of a record kept properly for six months is enormous, because it shows a pattern rather than presenting a single grievance. Our guides on documenting co-parenting and what counts as a usable record cover how to build one without letting it take over your life.

Things that make your position worse

Some of the most common reactions to a breach are the ones that cost parents the most:

• Withholding the child in return. Two wrongs are two breaches, and the court sees them both.
• Stopping child maintenance. It is a separate obligation, the Child Maintenance Service does not link the two, and doing it gives the other parent something to point at.
• Questioning your child about the other parent. Children report this, and it is read as putting them in the middle.
• Turning up at the other parent's home unannounced. It very rarely helps and often ends up in the evidence against you.
• Sending angry messages. Every one of them is a document the other side can use. If you cannot write it calmly, wait. The communication rules that keep parents out of court are worth ten minutes of your time before you reply to anything.

The realistic timeline

Enforcement is not instant. You apply to the court that made the order; the case is listed for a hearing, which usually means weeks rather than days. The judge may direct you to mediation, ask for a report on the family, or order a further hearing before deciding anything.

Expect months, not weeks, and plan your life around that. Nothing improves faster because you sent three emails in a day, and a lot improves when the other parent can see that the schedule holds whether or not they cooperate.

Making this the last time you need it

Two things reduce the odds of being back in the same position. The first is specificity: an order that names the day, the time and the place is far harder to breach than one that leaves the detail open. The second is a schedule that does not depend on goodwill to function — one both parents can see, with changes recorded rather than debated.

If your co-parent will not use it, the guide to co-parenting with someone who will not engage explains how to keep a usable record on your own. And if the arrangement itself needs rebuilding rather than enforcing, the parenting plan checklist is the place to start.
