Parenting plan vs child arrangements order
Key facts
- A parenting plan is a flexible written agreement between parents. A child arrangements order is a court order that is enforceable.
- A parenting plan is not legally binding on its own, but it is a clear record that courts take seriously.
- A child arrangements order sets out who a child lives with and spends time with, under section 8 of the Children Act 1989.
- Most separated parents use a parenting plan and never need a court order.
- You can start with a plan and apply for an order later if arrangements are not being kept to.
When parents separate, they need a shared understanding of how they will raise their children across two homes. There are two main ways to record that: a parenting plan or a child arrangements order. They are often confused, but they do very different jobs. This guide compares them side by side so you can see which fits your situation.
The short version is that a parenting plan is flexible and a child arrangements order is enforceable. One is a working agreement you can adjust as your children grow; the other is a formal order backed by the court. This is general information, not legal advice. For how these fit into making agreements binding, see our guide to the memorandum of understanding.
What is a parenting plan?
A parenting plan is a written agreement between parents that sets out the practical arrangements for their children. It covers the weekly routine, holidays and special days, changeovers, how you will communicate, and how you will make bigger decisions together. Many parents write one with the help of a mediator after agreeing arrangements in mediation.
A parenting plan is flexible by design. You can update it as your children get older, as school or work changes, or as new situations come up. It is not filed with a court and it does not need a judge’s approval. Our full guide to parenting plans shows exactly what to include and how to build one that lasts.
What is a child arrangements order?
A child arrangements order is a court order made under section 8 of the Children Act 1989. It sets out who a child lives with and who they spend time with, using those modern terms rather than the old words custody and access. Because it is a court order, it is enforceable: if one parent does not follow it without good reason, the other can ask the court to step in.
An order can be made when parents agree, as part of a consent order, or when a judge decides arrangements because the parents cannot. Applying to court for a children matter is usually made on form C100, and you normally need to have attended a MIAM first. Our page on child arrangements through mediation explains how many families reach agreement without ever needing an order.
Parenting plan vs child arrangements order: a comparison
The table below sets out the main differences at a glance. Neither option is better in the abstract. What matters is how much certainty your family needs and how well the two of you are able to work together.
| Parenting plan | Child arrangements order | |
|---|---|---|
| What it is | A written agreement between parents | A court order under the Children Act 1989 |
| Legally binding | No | Yes |
| Enforceable | No | Yes, by the court |
| Flexibility | High, adjust it any time together | Low, changing it needs the court’s agreement |
| How you get it | Agree it, often in mediation | Apply to court, or ask the court to seal an agreed order |
| Cost | No court fee | Court fee applies if you apply on a C100 |
| Best when | You can co-operate and want to adapt as children grow | You need certainty or arrangements are not being kept to |
How a child arrangements order is made, step by step
If you cannot agree and decide to ask the court to decide, the route is set out below. Even then, the court expects you to have tried to resolve things out of court first, which is why a MIAM comes at the start.
| Step | What happens |
|---|---|
| MIAM | You attend a mediation information and assessment meeting, unless an exemption applies, to consider mediation before court |
| C100 application | You apply to the family court on form C100, setting out what order you are asking for |
| Safeguarding checks | Cafcass carries out background checks and speaks to both parents before the first hearing |
| First hearing (FHDRA) | A first hearing where the court and Cafcass try to help you reach agreement |
| Decision | If you still cannot agree, the court gathers evidence and decides, putting the child’s welfare first |
Many cases settle at or before the first hearing, and any agreement can be turned into an order by consent. If you would rather keep control, our comparison of which non-court option is right sets out mediation and the alternatives.
Which one is right for your family?
Most separated parents use a parenting plan and never need a court order. A plan works well when you are able to communicate and want the freedom to adjust things as your children grow. It keeps decisions in your hands and avoids the cost and formality of court. Many parents find that a clear, written plan is all they ever need.
A child arrangements order tends to suit families where more certainty is needed, for example where trust has broken down, where one parent is not sticking to what was agreed, or where a specific issue needs the weight of a court behind it. Some parents also want the reassurance of an enforceable order even where things are amicable.
You are not locked in
Choosing a parenting plan now does not stop you applying for an order later. Many families start with a plan and only involve the court if arrangements stop working. Equally, an order can sit alongside a plan that fills in the day-to-day detail.
What the judge looks at: the welfare checklist
When a court is asked to make a child arrangements order, the child’s welfare comes first. The judge works through a set of factors known as the welfare checklist, in section 1(3) of the Children Act 1989. These include:
- The child’s own wishes and feelings, considered in light of their age and understanding
- Their physical, emotional and educational needs
- The likely effect on them of any change in their situation
- Their age, sex, background and any characteristics the court thinks relevant
- Any harm they have suffered or are at risk of suffering
- How capable each parent is of meeting the child’s needs
- The range of orders available to the court
The court also applies the no order principle: it will not make an order unless doing so is better for the child than making none. This is a big reason parents are encouraged to agree a plan where they safely can, rather than asking a judge to impose one.
Parental responsibility and how it fits in
Neither a parenting plan nor a child arrangements order changes who holds parental responsibility, the legal responsibility for a child’s upbringing. Mothers have it automatically, and most fathers have it if they are married to the mother or named on the birth certificate. A child arrangements order that says a child lives with a parent can give that parent parental responsibility if they do not already have it, but the order is mainly about where the child lives and who they see.
Understanding parental responsibility matters because it covers the bigger decisions, such as schooling and medical care, which both holders share. A good parenting plan usually records how you will make those decisions together, whichever route you take.
Can you have both?
Yes, and many families do. A child arrangements order might set out the framework, who the child lives with and the broad pattern of time with each parent, while a parenting plan fills in the practical detail the court would never include, such as how you handle homework, screen time or messaging between homes. The order gives certainty on the big points and the plan keeps everyday life running smoothly.
Good communication makes either option work better. Whatever you choose, keeping conflict away from your children is what matters most, which is why many parents also work on co-parenting communication.
A child arrangements order is made under section 8 of the Children Act 1989 and sets out who a child lives with and who they spend time with. In every decision about a child’s upbringing, section 1 makes the child’s welfare the court’s paramount consideration, and section 1(3) sets out the welfare checklist the court works through. The court also follows the no order principle: it will not make an order unless doing so is better for the child than making none.
What happens if a child arrangements order is broken?
A parenting plan is not enforceable, so if it is ignored the usual route is to update it or, if needed, apply for an order. A child arrangements order is different: if one parent breaks it without a reasonable excuse, the other can apply to enforce it on form C79. The court has a range of powers, and it always keeps the child’s welfare at the centre.
Where a breach is proved to the criminal standard, beyond reasonable doubt, and there is no reasonable excuse, the court can make an enforcement order requiring between 40 and 200 hours of unpaid work, order one parent to compensate the other for financial loss, vary the arrangements, or in serious cases treat the breach as contempt of court. In practice, judges often start by trying to understand why the order is not working and by encouraging the parents back to agreement. Our guide on what happens if an agreement breaks down walks through the options.
Common mistakes to avoid
- Assuming a parenting plan can be enforced like a court order. It cannot, though it is strong evidence of what you agreed.
- Rushing to court when a short return to mediation would resolve the issue faster and more calmly.
- Writing a plan that is too vague, so it does not help when a disagreement comes up.
- Forgetting to review the plan as children grow and routines change.
- Thinking an order removes the need to communicate. The everyday detail still needs co-operation.
Leah and Marcus agreed a routine for their two children in mediation and wrote it into a parenting plan. For two years it worked well and they adjusted it themselves each September. When Marcus’s job moved and he started missing agreed weekends, Leah worried the plan was no longer being kept to. They returned to mediation, updated the plan, and agreed that if it slipped again they would ask the court to make a child arrangements order for certainty. Having the plan in place made that conversation far easier, because the arrangements were already written down.
Frequently asked questions
Is a parenting plan legally binding?
No. A parenting plan is a written agreement, not a court order, so it is not legally binding on its own. It is still a clear and useful record that courts take seriously if a dispute later arises.
What is the difference between a parenting plan and a child arrangements order?
A parenting plan is a flexible agreement you make between yourselves. A child arrangements order is a court order that is enforceable. The plan can be changed any time; the order can only be changed with the court’s agreement.
Do I need a court order for child arrangements?
Most parents do not. If you can agree and co-operate, a parenting plan is usually enough. A court order is generally for when you need certainty or arrangements are not being kept to.
Can I turn a parenting plan into a court order?
You can ask the court to make a child arrangements order that reflects what you have agreed. Alternatively, if you cannot agree, you can apply on a C100, usually after attending a MIAM.
Can we use both a plan and an order?
Yes. An order can set out the framework while a parenting plan fills in the day-to-day detail the court would not include, such as communication and routines.
How is a child arrangements order enforced?
If a parent breaks it without a reasonable excuse, the other can apply on form C79. The court can order unpaid work of 40 to 200 hours, order compensation for financial loss, vary the arrangements, or treat a serious breach as contempt.
How long does a child arrangements order last?
It usually lasts until the child is 16, though the court can extend it to 18 in some cases. A parenting plan lasts as long as you both find it useful and can be updated at any time.
Does a parenting plan need to be signed or witnessed?
No. A parenting plan does not need to be signed or witnessed to be useful, though many parents do sign and date it. Its value is as a clear, agreed record, not as a formal legal document.
