Child Arrangement Agreement UK 2026: Custody, Contact & Legal Requirements

What a Child Arrangement Order Covers

“Lives with” provisions: Specifies which parent the child lives with primarily, or whether they split time equally between both homes.

“Spends time with” provisions: Sets out the contact schedule with the non-resident parent, including weekdays, weekends, and overnight stays.

Holiday arrangements: How school holidays, Christmas, birthdays, and other significant dates are divided.

Handover arrangements: Where and when children are collected and returned.

A child arrangement order does not cover child maintenance (that’s handled separately through the Child Maintenance Service or private agreement) or major decisions about the child’s upbringing (that requires a specific issue order or prohibited steps order).

How Long Does a Child Arrangement Order Take in the UK?

A child arrangement order typically takes 6–12 months from application to final order, though complex or contested cases can take 18 months or longer. Uncontested cases where both parents agree can be resolved in 3–4 months.

Timeline Breakdown

Week 1–4: Application submitted (Form C100), court fee paid, papers served on the other parent.

Week 4–8: Cafcass (Children and Family Court Advisory and Support Service) carries out safeguarding checks and may speak to both parents.

Week 6–10: First hearing (FHDRA — First Hearing Dispute Resolution Appointment). The court explores whether agreement can be reached without a full trial.

Month 3–6: If agreement isn’t reached, the court may order a Cafcass report (section 7 report) assessing the child’s welfare. This typically takes 12–16 weeks.

Month 6–12: Dispute Resolution Appointment (DRA) to narrow issues. If still not resolved, a final hearing is listed.

Month 9–18: Final hearing where a judge makes a binding decision after hearing evidence from both parents.

Factors That Slow Cases Down

Cases take longer when: there are allegations of domestic abuse (requiring fact-finding hearings), Cafcass is overloaded (causing report delays), either parent is uncooperative or repeatedly changes position, or the case involves international elements or relocation applications.

The fastest route is reaching agreement through mediation before or during proceedings. Courts actively encourage this and will ask what attempts have been made to resolve matters outside court.

How Long Does a Child Arrangement Order Last in the UK?

A child arrangement order lasts until the child turns 16, unless the court specifies otherwise. In exceptional circumstances, the order can be extended until the child turns 18.

When Orders End Earlier

Agreement between parents: If both parents agree to vary arrangements informally and it’s working well, they don’t need to follow the order strictly — though the order remains in place as a fallback.

Child’s own wishes: As children get older (typically from around 10–12), their views carry increasing weight. Teenagers often make their own decisions about contact regardless of what an order says.

Variation application: Either parent can apply to vary or discharge the order if circumstances change significantly — for example, relocation, new partners, changes to work patterns, or concerns about the child’s welfare.

What Happens at 16?

The order automatically ends when the child turns 16. After this, contact arrangements are effectively the child’s own decision. Courts very rarely make orders about 16–18 year olds unless there are exceptional circumstances (such as a child with significant disabilities who cannot make their own decisions).

If your child will be travelling abroad with one parent, you may need a travel consent letter from the other parent, regardless of what the child arrangement order says.

How Much Is a Child Arrangement Order in the UK?

The court fee to apply for a child arrangement order is £232. However, total costs depend on whether you use a solicitor and whether the case is contested.

Cost Breakdown

Court fee (Form C100): £232 (fee exempt if receiving certain benefits or on low income)

Mediation (if required): £100–£150 per session, typically 3–5 sessions (£300–£750 total). Legal aid may cover this.

Solicitor costs (uncontested): £1,500–£3,000 for help with paperwork, advice, and representing you at hearings

Solicitor costs (contested): £5,000–£20,000+ depending on complexity and number of hearings

Barrister fees (if needed): £1,000–£3,000 per hearing day

Self-Representation

Many parents represent themselves (litigants in person) to save costs. The court is used to this and will explain procedures. However, self-representation is challenging in complex cases, particularly where there are allegations of abuse or where the other parent has legal representation.

Legal Aid

Legal aid for private family cases was largely removed in 2013. It’s now only available if there’s evidence of domestic abuse or child abuse, you’re applying for certain protective orders, or the case involves child abduction. If eligible, legal aid covers solicitor costs and court fees.

Is a Parenting Plan Legally Binding in the UK?

No — a parenting plan is not legally binding in England and Wales. It is a voluntary agreement between parents that sets out how they will raise their children, but it cannot be enforced by a court if one parent doesn’t follow it.

Parenting Plan vs Child Arrangement Order

When a Parenting Plan Is Enough

A parenting plan works well when: both parents communicate reasonably, there’s no history of domestic abuse or controlling behaviour, both parents prioritise the children’s needs over conflict, and arrangements are likely to remain stable.

When You Need a Court Order

A court order is advisable when: one parent is uncooperative or unpredictable, there are safeguarding concerns about the children, one parent wants to relocate (within the UK or abroad), you need legal certainty about arrangements, or informal agreements have repeatedly broken down.

Even if you start with a parenting plan, you can apply for a court order later if circumstances change or the agreement stops working.

Can a Mother Legally Stop a Father From Seeing His Child in the UK?

No — a mother cannot legally stop a father from seeing his child simply because she wants to. UK law starts from the presumption that involvement of both parents in a child’s life is in the child’s best interests, unless there are welfare concerns.

When Contact Can Be Restricted

Courts will only restrict or prevent contact if there is evidence that contact would harm the child. This includes: proven domestic abuse (physical, emotional, or coercive control), proven child abuse or neglect, serious mental health issues affecting parenting capacity, substance abuse that puts the child at risk, or a genuine risk of abduction.

Even where there are concerns, courts usually try to maintain some form of contact — often supervised contact at a contact centre until concerns are addressed.

What a Father Can Do

If a mother is preventing contact without legitimate welfare reasons, the father can: attempt mediation to resolve the dispute, apply for a child arrangement order (Form C100), and if an order exists and is being breached, apply for enforcement.

Courts generally take a negative view of parents who obstruct contact without good reason. Persistent, unjustified obstruction can result in: costs orders against the obstructing parent, transfer of the child’s residence to the other parent, or in extreme cases, imprisonment for contempt of court.

Parental Responsibility Matters

If the father has parental responsibility (automatic if married to the mother, or if named on the birth certificate after December 2003, or acquired through agreement or court order), he has equal legal standing to make decisions about the child. A mother cannot unilaterally exclude a father with parental responsibility from the child’s life.

For more on acquiring parental responsibility, see our parental responsibility agreement guide.

How Do You Write an Agreement Between Two Parents?

Writing a parenting agreement involves documenting the practical arrangements for your children in a clear, detailed way that both parents can follow. The more specific the agreement, the fewer disputes later.

Step 1: Cover the Basics

Start with fundamental arrangements: where the child will live primarily, the regular contact schedule (weekdays, weekends, overnights), school pick-ups and drop-offs, and who provides day-to-day care.

Step 2: Address Holidays and Special Occasions

Set out how you’ll divide: school holidays (half-term, Easter, summer, Christmas), Christmas Day and Boxing Day (alternating years?), birthdays (child’s birthday and each parent’s birthday), Mother’s Day and Father’s Day, and religious or cultural celebrations.

Step 3: Document Handover Arrangements

Specify: where handovers happen (neutral location, school, one parent’s home), what time handovers occur, who is responsible for transport, and what happens if someone is late or can’t make it.

Step 4: Cover Communication

Agree on: how the child will communicate with the other parent between visits (phone, video call), how parents will communicate with each other about arrangements, and minimum notice for changes to the schedule.

Step 5: Address Major Decisions

Document how you’ll make decisions about: education (school choice, tutoring), medical treatment (including vaccinations), religious upbringing, and activities and hobbies.

Step 6: Plan for Changes

Include provisions for: how arrangements will change as the child gets older, what happens if one parent wants to relocate, and how disputes will be resolved (mediation before court).

Who Needs to Fill Out a C100 Form?

Form C100 is the application form for a child arrangement order, specific issue order, or prohibited steps order. It must be completed by any parent or person with parental responsibility who wants to ask the court to make an order about a child.

When You Need Form C100

Child arrangement orders: To establish or formalise where a child lives and contact arrangements.

Specific issue orders: To ask the court to decide a specific question about the child’s upbringing — for example, which school they should attend or whether they can be vaccinated.

Prohibited steps orders: To prevent the other parent from taking a specific action — for example, removing the child from the UK or changing their school without consent.

Before You Can Apply

In most cases, you must attend a Mediation Information and Assessment Meeting (MIAM) before submitting Form C100. A mediator will assess whether mediation might help resolve your dispute without going to court. You’ll need to attach a signed FM1 form confirming you’ve attended a MIAM (or are exempt).

Exemptions from MIAM

You don’t need to attend a MIAM if: there’s evidence of domestic abuse, there’s an urgent risk to the child’s safety, the other parent is in prison, you’re applying for a consent order (both parents agree), or the child is subject to ongoing child protection proceedings.

Where to Get Form C100

Form C100 is available free from the gov.uk website. It can be submitted online or in paper form to your local family court. The £232 court fee must be paid when you submit (unless you’re exempt).

What Is the Typical Child Custody Arrangement in the UK?

The most common arrangement in the UK is for children to live primarily with one parent (usually the mother) and spend regular time with the other parent, typically including alternate weekends and one midweek evening.

Common Arrangements

Primary residence with regular contact: Child lives with one parent, sees the other every other weekend (Friday evening to Sunday evening) plus one midweek visit. Most common arrangement.

Shared care (50/50): Child spends equal time with each parent — for example, week on/week off, or 2-2-3 pattern. Requires parents to live close to each other and communicate well.

Alternate weekends only: Child sees non-resident parent every other weekend. Often used when distance, work patterns, or past conflict limits more frequent contact.

Supervised contact: Contact takes place at a contact centre or with a supervisor present. Used where there are safeguarding concerns that need monitoring.

What Courts Consider

When making orders, courts apply the welfare checklist in section 1(3) of the Children Act 1989: the child’s physical, emotional, and educational needs, the likely effect of any change in circumstances, the child’s age, sex, background, and any relevant characteristics, any harm the child has suffered or is at risk of suffering, how capable each parent is of meeting the child’s needs, the range of powers available to the court, and (most importantly) the child’s own wishes and feelings, given their age and understanding.

There’s No “Standard” Order

Courts decide each case on its individual facts. What’s right for one family won’t be right for another. The key principle is the child’s welfare — not equal rights for parents or what arrangement feels “fair” to adults.

What Is the Biggest Mistake in a Custody Battle?

The biggest mistake is treating it as a battle to be won against the other parent, rather than focusing on what’s genuinely best for the child. Courts see through parents who prioritise “winning” over their children’s welfare — and it damages their case.

Common Mistakes That Hurt Your Case

Bad-mouthing the other parent: Speaking negatively about the other parent to the child, or in evidence, makes you look hostile and unable to promote the child’s relationship with both parents. Courts value parents who support contact with the other parent.

Using children as messengers: Making children pass messages between parents, asking them to report on the other parent’s household, or putting them in the middle of adult conflict. Cafcass officers watch for this and report it.

Making false allegations: Exaggerating or fabricating concerns about the other parent’s behaviour. Courts are experienced at identifying false allegations — and making them destroys your credibility on everything else.

Refusing to engage with mediation: Courts expect parents to attempt mediation before and during proceedings. Blanket refusal to mediate suggests you’re more interested in conflict than resolution.

Ignoring court directions: Missing deadlines, failing to file documents on time, or not attending hearings. This frustrates judges and suggests you don’t take the process seriously.

Breaching existing orders: If there’s already an order in place (even an interim order), breaching it — even if you think you’re justified — damages your credibility and can result in enforcement action against you.

What Courts Want to See

Courts respond well to parents who: focus on the child’s needs rather than their own grievances, support the child’s relationship with the other parent, engage constructively with mediation and court processes, comply with court directions and orders, present evidence calmly and factually (not emotionally), and demonstrate flexibility and willingness to compromise.

The parent who presents as child-focused and reasonable will usually do better than the parent who presents as angry, obstructive, or vengeful — regardless of who was “at fault” in the relationship breakdown.
