What to do when your co-parent won't follow the custody agreement
When a co-parent stops following what was agreed, the steps you take and the records you keep determine what options you have.
When a custody agreement stops being followed, it is one of the most frustrating situations in co-parenting. You reached an agreement. Both parties understood what was expected. And now the other parent is not following it, whether that is missing scheduled time, showing up late, blocking contact, or simply ignoring what was decided.
What you do next, and how you document what is happening, makes a significant difference to what options are available to you.
Start by distinguishing a pattern from an incident
A one-off deviation from a custody agreement is not the same as a pattern of non-compliance. How you respond should reflect which one you are dealing with.
A single missed visit, a late handover on one occasion, or a last-minute change during an unusual period may be frustrating but is unlikely to be the basis for formal action. Life genuinely does get in the way sometimes, and courts expect parents to absorb occasional deviation without escalating immediately.
A pattern is different. Repeated missed visits. Consistent lateness. A series of last-minute cancellations. Contact being blocked on multiple occasions without clear reason. These are not individual failures; they are a picture of how the agreement is actually being treated, and that picture is what matters in any formal process.
The way you establish a pattern is through records. Not memory, not a general sense that things have been difficult, but a specific log of what was agreed, what actually happened, and when. That log is the difference between being able to demonstrate a pattern and simply asserting one.
Put it in writing first
Before taking any formal step, raise the issue directly with your co-parent in writing.
This serves two purposes. It gives the other parent an opportunity to address the problem without involving anyone else, which is always the preferable outcome. And it creates a record that you raised the issue, what you said, and what response you received, or did not receive.
Keep the message factual and specific. Name the dates and occasions where the agreement was not followed. State what the agreement says and what happened instead. Ask directly what the other parent’s understanding of the arrangement is and how they intend to address it going forward.
Avoid accusatory language. A message that reads as an attack is less likely to get a useful response and more likely to escalate the situation. A message that is calm, specific, and focused on the arrangement rather than the other parent’s character is harder to dismiss and easier to rely on later.
Consider mediation before legal steps
If direct communication has not resolved the issue, mediation is the appropriate next step before any court application in most circumstances.
A mediator does not take sides or make decisions. Their role is to help both parents have a conversation they cannot have on their own, focused on the specific problem and what a workable solution looks like. For custody agreement disputes, this often means clarifying what was meant by specific terms, addressing a change in circumstances that has made the original arrangement unworkable, or establishing a clearer framework going forward.
Mediation is significantly faster and cheaper than court proceedings, and courts in most jurisdictions expect parents to have attempted it before filing an application. Arriving in court without having tried mediation, when it was available and appropriate, reflects poorly.
Keep a record of the mediation process: when it was offered, whether the other parent engaged, and what the outcome was. If mediation is refused outright by the other parent, that refusal is itself relevant information.
When the agreement is a formal court order
If your custody agreement has been formalised as a court order and it is being breached, the options available to you are stronger than if the agreement is informal.
In the US, a violation of a custody order can be raised through a motion for contempt. Courts take breaches of their own orders seriously, and repeated or deliberate violations can result in modification of the order, fines, or in serious cases, more significant consequences for the non-compliant parent.
In England and Wales, a breach of a child arrangements order can be addressed through an enforcement application. The court can impose a range of responses, from a warning through to unpaid work requirements, and in serious cases can vary the order itself, including changing which parent the child lives with primarily.
In both systems, what the court needs to see is evidence. Not a general account of things being difficult, but a specific record of what the order says, what actually happened on particular dates, and what attempts were made to resolve the matter before the application was filed.
If contact is being withheld entirely
Contact being withheld altogether, where the other parent is refusing to allow any time with the child, is treated more seriously than late handovers or missed individual visits.
If this is happening and there is a court order in place, legal advice is warranted without delay. An urgent application can be made in cases where contact is being denied in clear breach of an order.
If there is no order, an application for one establishes what the arrangement should be and creates the formal basis for enforcement if the problem continues. Courts are generally reluctant to see a parent denied a relationship with their child without clear welfare reasons, and an unjustified withholding of contact is something courts respond to.
Throughout this process, keep documenting every attempt to have contact and every occasion on which it was refused. Note the date, how you attempted to make contact, what the response was, and how the child was affected if you were able to observe it. This record is the foundation of any application you make.
What courts look at
When a court hears an application related to a custody agreement not being followed, it is looking at several things simultaneously.
The first is what the agreement or order actually says, and whether the alleged breach is clear or ambiguous. Agreements that are vaguely worded give more room for both parties to claim they were following it. Specific, detailed agreements are much easier to enforce.
The second is the pattern over time. A single incident presented as a crisis tends not to land the same way as a documented pattern of behaviour across several months. Courts are experienced at identifying which is which.
The third is the conduct of both parents. A parent applying for enforcement who has themselves been difficult about arrangements, communication, or compliance in other areas is in a weaker position than one who has a clean record of attempting to make things work. Courts look at the full picture, not just the specific complaint.
The fourth is the impact on the child. Ultimately the court is asking what is in the child’s best interests. Evidence of how the child has been affected by the disruption to their arrangements, described factually and without editorialising, is relevant to that assessment.
Building your record from today
If you are dealing with a co-parent who is not following the custody agreement, the most useful thing you can do right now is start keeping a clear, dated log of what is happening.
For each occasion where the agreement is not followed, note the date, what was agreed, what actually happened, any communication around it, and what you did in response. Do this at the time, not reconstructed later. A log built entry by entry as events happen is a fundamentally different kind of record from one assembled from memory when things reach a critical point.
That record is what turns a difficult situation into something you can actually act on, whether through a direct conversation, mediation, or a formal application. Without it, you are relying on your account against the other parent’s. With it, you have something a court can work with.
