Clear, detailed guide on enforcing Child Arrangements Orders in England and Wales: how to apply to court, legal standards for breach and reasonable excuse, evidence and forms needed, possible sanctions like enforcement orders, fines or unpaid work, and key welfare considerations to support families through enforcement proceedings.
A Child Arrangements Order (CAO) is a legally binding decision made by a family court that determines where a child lives and how they spend time or have contact with parents or others. While most parents comply with these orders, disagreements and breaches can occur. When one party does not follow the terms of a CAO, the law provides specific procedures to enforce the order through the courts. This article explains how enforcement works in practice, the steps involved in applying to court, the legal standards that apply, and the potential outcomes when a child arrangements order is not complied with in England and Wales.
What It Means to Enforce a Child Arrangements Order
Enforcing a child arrangements order means asking the family court to take legal action against someone who has failed to comply with the terms of the order without a reasonable excuse. A breach might involve failing to make a child available for time ordered, refusing contact, or ignoring other provisions of the order. Family courts treat compliance seriously because failing to follow a CAO can affect a child's stability and welfare.
Before a court can enforce a CAO, the existing order must include a warning notice that explains the consequences of non‑compliance. Most orders made since December 2008 include this automatically; older orders may require a warning notice to be attached first.
Step‑by‑Step: Applying for Enforcement
1. Try to Resolve the Issue Informally
Judges and advisers encourage parties to attempt to resolve disputes amicably where possible, including through discussion or voluntary mediation (unless there are safety concerns such as domestic abuse). This step can save time and cost for both families and the court.
2. Gather Evidence of Non‑Compliance
Before applying to court, it is important to document the specific ways in which the other party has failed to comply with the child arrangements order. This may include dates, times, communications, and any relevant correspondence showing breaches. The court will consider this evidence when deciding whether enforcement is appropriate.
3. Complete and Submit Form C79
The formal application to enforce a child arrangements order is made using Form C79. This is submitted to the family court where your existing order was made, or to another suitable family court. The form allows you to state:
- The details of the existing child arrangements order.
- What terms have not been complied with.
- The evidence supporting your claim of non‑compliance.
If your order pre‑dates compulsory warning notices, you can first attach a warning notice using Form C78 before applying for enforcement.
There is a court fee for submitting Form C79 (around £263 at recent published levels), but you may be eligible for help with fees if you have a low income.
4. Court Reviews the Application
The court will review your application and the evidence of breach. Enforcement cases do not usually require a MIAM (mediation information assessment meeting) before application, although demonstrating attempts at resolution may be helpful.
How the Court Decides on Enforcement
Legal Standard: Reasonable Excuse
Under Section 11J of the Children Act 1989, the court will make an enforcement order only if it is satisfied that the person has failed to comply with a child arrangements order without a reasonable excuse. The respondent must show, on the balance of probabilities, that any failure to comply was justified.
Welfare Considerations
The court must also consider the welfare of the child when deciding enforcement matters, including:
- The reasons for non‑compliance.
- The impact of non‑compliance on the child.
- Whether enforcement is necessary and proportionate to the breach.
- Any advice from Cafcass (Children and Family Court Advisory and Support Service).
- The statutory welfare checklist under the Children Act 1989.
Possible Court Outcomes
If the court finds that a breach has occurred and there is no reasonable excuse, it has a range of powers to enforce compliance and address the breach. These include:
Enforcement Orders
Under Section 11J, the court can make an enforcement order, which may impose:
- Unpaid work requirements (community service) on the person in breach.
- Fines for contempt of court.
- An order for compensation to reimburse financial losses caused by the breach (such as travel costs).
- Referral to a separated parents information programme or mediation support.
- Variation of the original child arrangements order to clarify or update terms.
- Suspended enforcement orders that take effect only if further breaches occur.
- Committal (imprisonment) in serious or repeated cases of contempt.
These sanctions are designed to encourage compliance and uphold the authority of the court, not solely to punish. The severity of the penalty generally reflects the seriousness and persistence of the non‑compliance.
Enforcement Versus Variation
In some situations, repeated breaches may indicate that the existing order is no longer workable. In these cases, instead of enforcement alone, the court might decide to vary the child arrangements order to reflect new circumstances, provided such variation is consistent with the child's welfare. This may involve modifying contact times or living arrangements.
Risks and Practical Considerations
Reasonable Excuse
If a respondent shows that they had a reasonable excuse for non‑compliance – for example, genuine illness, transport issues beyond their control, or emergencies – the court may decline to enforce the order, or take a less severe approach. It is the respondent's responsibility to demonstrate this.
Costs and Timeframes
Enforcement proceedings require preparation, evidence, and court fees. Cases can take several weeks to months depending on the complexity and the court's schedule. Legal representation can assist with preparation but is not mandatory; many people submit Form C79 as litigants in person.
Maintaining the Child's Welfare
The welfare of the child remains central throughout enforcement proceedings. A primary aim is to protect the child's relationship with both parents or carers, so courts often consider measures like mediation or information programmes before or alongside enforcement sanctions.
Common Questions
Do I need legal representation to enforce an order?
No. Individuals can apply to enforce a child arrangements order without a solicitor, although specialist legal advice may help with evidence and court procedures.
What if the other parent says they had a good reason for breaching the order?
The court will review their explanation and decide whether it constitutes a reasonable excuse. If it does, the enforcement application may be refused or dealt with differently.
Can enforcement orders be appealed?
Yes. Decisions of the family court can be challenged by application to an appropriate appellate court, but strict time limits and procedural rules apply. Legal advice is recommended for appeal matters.
Key Takeaways
Enforcement of a Child Arrangements Order in England and Wales ensures that the terms of a legally binding family court order are respected. If a party fails to comply without a reasonable excuse, the other party can apply to court using Form C79. The family court will review evidence, consider the child's welfare, and may issue an enforcement order with a variety of sanctions, ranging from community work and fines to compensation and, in serious cases, imprisonment. Understanding the process, preparing clear evidence of breaches, and recognising the central importance of the child's welfare can help individuals pursuing enforcement navigate the court system effectively.
