A child arrangements order is a family court order that decides who a child is to live with, spend time with, or otherwise have contact with. GOV.UK explains this on its guide to making child arrangements if you divorce or separate, and HMCTS also confirms on the C100 application page that this is one of the orders you can apply for under the Children Act 1989.

For solicitors, family law teams, and private clients, it is important to understand not only what the order does, but also how related court documents are handled and served. WeProcess specifically lists child arrangements among the family law documents it handles on its guide to UK process serving.

What is a child arrangements order?

A child arrangements order is made under section 8 of the Children Act 1989. The legislation groups this order alongside prohibited steps orders and specific issue orders, while GOV.UK explains its practical purpose more clearly: it decides the arrangements for whom a child is to live with, spend time with, or otherwise have contact with. You can read the legal framework in the Children Act 1989, section 8 and the plain-English explanation on the GOV.UK page about children and the family courts.

In everyday terms, this is the order the court may use when parents or others with responsibility for a child cannot agree on living arrangements or contact arrangements.

When is a child arrangements order used?

A child arrangements order is usually used when agreement cannot be reached about where a child should live, how often they should see a parent, or what contact arrangements should be in place. GOV.UK states that if you cannot agree after mediation or other help, you can apply for a court order. The same GOV.UK guidance also says that applicants will usually need to show they have tried mediation before applying, unless an exemption applies. See making child arrangements if you divorce or separate and the HMCTS C100 application page.

This type of order is commonly relevant in:

separation and divorce cases
disputes about contact
disputes about where the child should live
changes to existing child arrangements
enforcement applications where an order is not being followed

If an existing order is not being complied with, HMCTS provides a separate C79 enforcement form.

Why this order matters

Child arrangements orders are important because they create a formal legal framework where agreement has broken down. In family law matters, the court’s approach is guided by the child’s welfare. The welfare principle is set out in section 1 of the Children Act 1989, which says the child’s welfare is the court’s paramount consideration when determining questions about a child’s upbringing.

That makes these cases particularly sensitive. Even where the order itself is clear, the practical handling of documents, notices, and supporting papers still matters.

Why proper service matters in family law cases

In family law, delay and uncertainty around paperwork can create unnecessary stress and slow down the progress of a case. Where a case involves child arrangements, parties often need confidence that documents have been delivered properly and that there is a clear record of what was served and when.

WeProcess highlights family law documents, including child arrangements, on its UK process serving guide and also notes on its article about legal document service times that child arrangement orders can fall within urgent same-day service matters depending on the circumstances.

For firms handling family cases regularly, using a professional process server can help provide:

clearer evidence of service
faster handling of urgent instructions
better visibility of progress
less administrative chasing

How child arrangements documents are typically handled

The exact service requirements will depend on the order, the stage of proceedings, and any directions from the court. In practice, firms often want sensitive family law documents handled carefully, quickly, and with a reliable evidence trail.

A professional process server will usually:

receive the papers and review the instructions
note any urgency or deadline
attend the address where service is required
record the outcome clearly
provide proof or a statement of service where needed

Child arrangements order vs prohibited steps order vs specific issue order

These three orders are closely related because they all sit under section 8 of the Children Act 1989. The HMCTS C100 page confirms that the same form can be used to apply for a child arrangements order, prohibited steps order, or specific issue order.

In simple terms:

a child arrangements order deals with where a child lives or spends time
a prohibited steps order prevents a particular step being taken without the court’s permission
a specific issue order resolves a particular dispute about a child’s upbringing

That distinction is useful for your content strategy too, because it gives you a natural path into the next posts in the series.

How WeProcess can help

WeProcess supports the service of family law documents across the UK and specifically references child arrangements among the document types it handles. Useful supporting pages to link in this post include:

That FL401 page also lists Child Arrangements Orders as a related family law order, which makes it a useful internal supporting link even though the page itself is centred on different applications.

Final thoughts

A child arrangements order is one of the most important family court orders in cases involving children after separation or dispute. It helps formalise arrangements about living and contact where agreement cannot be reached, and the court approaches these questions with the child’s welfare as the central consideration. GOV.UK and HMCTS both make clear that these orders sit within the wider Children Act 1989 framework and are commonly applied for using the C100 process.

For law firms and private clients, careful document handling still matters throughout the case. That makes this a strong next post in your Document Service Types series and a natural follow-on from the occupation order and non-molestation order content.
