Can I cancel a C100 form? Learn when you can withdraw a C100 application, what happens after filing, and the steps you should take before court.
Can I cancel a C100 form?
The short answer is yes, in some cases. However, it depends on where you are in the court process and whether the court has already taken action on your application.
Many parents file a C100 form during stressful moments. Later, things can change. You and the other parent may reach an agreement. You may decide mediation worked better than expected. Or you may simply feel going to court is no longer the right choice.
If you’re dealing with Child Arrangements, it’s important to understand what your options are before making any decisions.
In this guide, you’ll learn when you can cancel a C100 form, how to do it properly, and what happens after you ask the court to withdraw your application.
What Is a C100 Form?
A C100 form is used when you want the family court to make decisions about a child.
Parents or guardians use it to ask the court for a Child Arrangements Order or other orders involving children.
You might use it if you cannot agree on things like:
- Where your child should live
- When your child should spend time with each parent
- School or holiday arrangements
- Other important parenting decisions
Once you submit the form and the court accepts it, your case officially begins.
Can You Cancel a C100 Form After Submitting It?
Yes, but it’s not as simple as deleting an online form.
Once the court receives your C100 application, it becomes part of an active legal case.
That means you cannot simply tell the court you’ve changed your mind and expect everything to stop automatically.
Instead, you’ll usually need permission from the court to withdraw your application.
Whether the court agrees often depends on:
- How far the case has progressed
- Whether the other parent agrees
- Whether withdrawing is in the child’s best interests
The family court’s main concern is always the welfare of the child.

Why Would Someone Want to Cancel a C100 Form?
People change their minds for many reasons.
Some of the most common include:
- You Reached an Agreement
This is probably the biggest reason.
After filing the application, you and the other parent may finally sit down and work things out.
Instead of letting the court decide, you both agree on parenting arrangements.
That often makes continuing the court case unnecessary.
- Mediation Was Successful
Sometimes parents attend mediation after filing.
The conversations go better than expected, and both parents reach a solution without needing a judge.
When that happens, withdrawing the application may make sense.
- Circumstances Changed
Life rarely stays the same.
Maybe one parent moved closer.
Perhaps work schedules changed.
Or maybe the original problem simply no longer exists.
- The Application Was Filed Too Quickly
Family disputes can become emotional.
Some parents file a C100 form while upset or frustrated.
After emotions settle, they may realize court isn’t the best option.
Can You Cancel Before the First Hearing?
Yes.
In fact, this is usually the easiest time to ask the court to withdraw your application.
If the court hasn’t held the first hearing yet, the process is generally more straightforward.
However, the court still needs to approve your request.
Simply deciding not to attend isn’t enough.
Ignoring the hearing can create bigger problems.
Can You Cancel After Court Proceedings Have Started?
Yes, but it becomes more complicated.
Once hearings have taken place, the court has already invested time and resources into the case.
The judge will want to know:
- Why you want to withdraw
- Whether both parents agree
- Whether the child’s interests are protected
If the judge believes the child still needs court protection, they may refuse your request.
How Do You Withdraw a C100 Application?
The exact steps can vary depending on your situation.
Generally, you should:
- Tell the Court
- Write to the court explaining that you want to withdraw your application.
- Be clear about your reasons.
- Inform the Other Parent
- If possible, let the other parent know.
- If you’ve both reached an agreement, mention that in your request. Courts often look more positively on applications where both parents support the withdrawal.
- Wait for the Court’s Decision: The court will review your request. Sometimes a judge decides without another hearing. Other times, the court may discuss it during the next scheduled hearing.
- Don’t assume the case has ended until the court confirms it.
What Happens If the Court Refuses?
The case continues.
If the judge believes court involvement is still needed, you’ll usually need to attend future hearings.
Remember, the judge isn’t deciding what’s easiest for the parents.
They’re deciding what’s best for the child.
Will You Get Your Court Fee Back?
Usually, no.
Once your application has been processed, the court fee is generally non-refundable.
That’s why it’s worth thinking carefully before filing.
If you’re close to reaching an agreement, mediation may save both time and money.

Should You Cancel If You’ve Reached an Agreement?
Not always.
This surprises many parents.
Even if you’ve reached an agreement, you should think carefully before withdrawing.
Ask yourself:
- Will both parents stick to the agreement?
- Is everything written down clearly?
- Has communication improved?
- Could the same disagreement happen again?
If the agreement is stable, withdrawing may be the right choice.
If you’re unsure, it may be worth discussing your options with a family law solicitor before ending the case.
What If the Other Parent Doesn’t Agree?
You can still ask to withdraw.
However, the court may consider the other parent’s views before making a decision.
If the disagreement continues, the judge may decide the case should move forward.
Again, everything comes back to one question:
What’s best for the child?

Should You Skip the Hearing Instead?
No.
Skipping court is almost always a bad idea.
If you’ve changed your mind, tell the court properly.
Failing to attend could:
- Delay your case
- Waste court time
- Lead to further directions from the judge
Always wait for confirmation that your application has been withdrawn.
Can You Reapply Later?
Yes.
Withdrawing a C100 application doesn’t usually stop you from applying again in the future.
If circumstances change and disagreements return, you may be able to submit a new C100 application.
However, starting another case means going through the process again.
That may include mediation requirements unless an exemption applies.

Tips Before You Cancel a C100 Form
Before asking the court to withdraw your application, take a moment to think it through.
Consider these points:
- Make sure your agreement is realistic.
- Put parenting arrangements in writing.
- Keep your child’s needs first.
- Continue communicating respectfully with the other parent.
- Wait for official confirmation from the court before assuming the case has ended.
A little planning now can prevent future disagreements.
Common Mistakes to Avoid
Parents sometimes make decisions that create unnecessary problems.
Here are a few to avoid.
- Assuming the Case Ends Automatically: Submitting a withdrawal request doesn’t immediately close the case. Wait for the court’s decision.
- Ignoring Court Letters: Keep reading every letter you receive. The court may still ask you to attend a hearing.
- Making Verbal Agreements Only: If you’ve reached an agreement, write it down. Clear written arrangements help avoid misunderstandings later.
- Forgetting About the Child’s Best Interests: It’s easy to focus on ending the legal process. But every decision should still support your child’s wellbeing.
Final Thoughts
So, can I cancel a C100 form?
Yes, in many situations you can. But once the application has been filed, the process isn’t entirely in your hands. The court must usually approve your request to withdraw, especially if the case has already moved forward.
If you and the other parent have reached a genuine agreement that works for your child, withdrawing the application may be the right choice. Just be sure to follow the proper steps instead of assuming the case will end automatically.
Family court proceedings can feel overwhelming, but understanding your options helps you make informed decisions. Above all, keep your child’s best interests at the center of every choice you make.
