Learn how to change a child custody order in England and Wales. Step-by-step guide on the legal process, court hearings, and factors considered by the court. Ensure the child's welfare is protected in custody disputes.

In the UK, a child custody order-referred to as a Child Arrangements Order-sets out where a child will live and how they will spend time with each parent or other significant individuals. However, circumstances change over time, and there may come a point when it becomes necessary to change the existing child custody arrangements. This process can be complex, requiring legal intervention to ensure that the changes are in the child’s best interests.
This article provides a detailed overview of the legal process involved in changing a child custody order in England and Wales, including when it is possible to apply for a change, how the process works, and the factors courts consider when making decisions.
What is a Child Custody Order?
A Child Arrangements Order is a court order that determines where a child will live and how they will interact with their parents or other important individuals. These orders are typically issued when parents cannot agree on arrangements for the child’s care, or when the court needs to intervene to protect the child’s welfare.
If the situation changes-whether due to a parent's relocation, a change in the child's needs, or the emergence of new concerns-either parent may want to request a modification to the existing custody order.
Changing a child custody order involves a legal process that requires clear evidence and justification for the proposed changes, which must be in the child’s best interests.
When Can a Child Custody Order Be Changed?
There are several circumstances under which it may be possible to apply for a change to a Child Arrangements Order:
1. Significant Changes in Circumstances
- Relocation: If one parent wishes to move far away, such as to a different town or country, this may affect the child’s time with the other parent. The parent proposing the move would need to justify how the child's welfare will be protected.
- Changes in the Child's Needs: As children grow older, their needs may change, and the current arrangements may no longer be appropriate. For example, a child may want to live with the other parent due to educational needs or personal preferences.
- Health or Safety Concerns: If there are concerns about a parent's ability to care for the child due to health problems, substance abuse, or other factors, the child's welfare may no longer be safeguarded, making a change in the order necessary.
2. Non-compliance with Existing Orders
If one parent is not adhering to the terms of the existing Child Arrangements Order, such as refusing to allow the other parent time with the child, this could be grounds for applying for a change.
3. Changes in Parental Ability or Circumstances
- If a parent's circumstances change significantly, such as a change in their employment, lifestyle, or ability to care for the child, it may be appropriate to adjust the existing order. For instance, a parent who was previously unable to care for the child due to financial difficulties or a lack of housing may now be in a better position to have primary residence.
4. Domestic Violence or Abuse
If there is evidence that a parent has committed acts of domestic violence or abuse, the current custody arrangement may need to be altered to ensure the child's safety and welfare.
Legal Process for Changing a Child Custody Order
Step 1: Attempt Mediation
Before applying to the court, parents are typically required to attempt mediation to resolve disputes. Mediation is a process where a neutral third party, known as a mediator, helps the parents reach an agreement without going to court. This is often a more cost-effective and less adversarial approach than litigation.
- If mediation is unsuccessful, or if there are safety concerns that make mediation inappropriate (such as allegations of abuse), you will be given a Mediation Information and Assessment Meeting (MIAM) certificate. This is a prerequisite to making an application to the court.
Step 2: Apply for a Child Arrangements Order
Once mediation has been exhausted, you can apply to the Family Court for a change to the existing child custody order. To do this, you will need to fill out a C100 application form, which is available online from the government website or from your local Family Court.
- The C100 form requires details of the existing order, the proposed changes, and the reasons for requesting the change. You must also provide evidence of any significant changes in circumstances or issues that support the need for a modification.
Step 3: Submit the Application and Pay the Court Fee
You will need to submit your completed C100 form to the Family Court and pay the court fee. As of 2023, the fee for applying for a Child Arrangements Order is £232, although this may vary. You may qualify for a fee waiver if you have a low income or receive certain benefits.
If the application is particularly urgent, you may be able to request an expedited hearing by indicating this on your application.
Step 4: Court Hearings and Evidence
After the application is submitted, the court will schedule a hearing to consider the request for a change in the child custody arrangement. The first hearing is typically called a First Hearing Dispute Resolution Appointment (FHDRA), where the court will assess the case and may refer the matter back to mediation or suggest a resolution.
If the issue is more complex, the court may schedule further hearings to allow both parents to present their evidence. At these hearings, you may be asked to provide:
- Witness statements from you or others involved, such as family members or friends.
- Expert reports from professionals, such as social workers, psychologists, or child welfare experts.
- Evidence of any concerns regarding the child's welfare, such as medical records, police reports, or court documents.
Step 5: The Court's Decision
After reviewing all the evidence, the court will issue a ruling regarding the requested changes. If the court agrees that a change in the custody arrangement is in the child's best interests, it will issue a new Child Arrangements Order. This order will specify where the child will live, how contact will be arranged, and who will make decisions about the child's welfare.
If either parent disagrees with the court's decision, they may have the right to appeal the ruling. However, appeals are only allowed in limited circumstances, such as when there has been a significant error in law or procedure.
Factors the Court Considers When Changing a Child Custody Order
When deciding whether to change a child custody order, the court will always consider the child's best interests as the most important factor. The court must assess:
- The child's welfare and needs, including emotional, educational, and physical needs.
- The child's relationship with each parent and other important figures, such as siblings or grandparents.
- The child's wishes and feelings, particularly if they are old enough and mature enough to express a clear preference.
- The ability of each parent to care for the child and meet their needs.
- Any history of domestic violence, neglect, or substance abuse.
- The impact of any proposed change on the child's well-being and stability.
Risks and Considerations
- Cost: The application process, especially if the case is contested, can be expensive. Legal fees, court fees, and expert witness costs can quickly accumulate.
- Time: Changing a child custody order can take several months, especially if there are multiple hearings or disagreements between parents. Delays in the court system are common.
- Emotional Impact: Court proceedings can be stressful for both parents and children, particularly if there is ongoing conflict. Prolonged disputes can affect the child's emotional well-being.
Common Questions from our Readers
Can I change a child custody order without going to court?
You may be able to make informal changes to a child custody arrangement if both parents agree. However, if you want the changes to be legally enforceable, you will need to apply to the court for a new Child Arrangements Order.
What happens if one parent refuses to comply with the court order?
If a parent refuses to comply with the terms of the child custody order, the other parent can return to court to enforce the order. The court can issue further orders or impose penalties if non-compliance continues.
How do I know if I need to apply for a change?
If the current custody arrangement is no longer in the best interests of the child, or if there are significant changes in circumstances (e.g., safety concerns, health issues, or a move), it may be appropriate to apply for a change.
Final Thoughts
Changing a child custody order is a significant legal process that requires careful consideration of the child's best interests. Whether due to changes in the child's needs, a parent's circumstances, or concerns for the child's safety, the legal process involves applying to the Family Court, providing evidence, attending hearings, and potentially receiving a new Child Arrangements Order. Understanding the steps and requirements involved will help ensure that the child's welfare remains the priority throughout the process.
