Relatives Applying for a Child Arrangements Order: Aunts, Uncles, Siblings and Kinship Carers

Who Counts as a Relative Under the Children Act

The Children Act 1989 defines "relative" as a grandparent, brother, sister, uncle, aunt, or step-parent — whether by full blood, half blood, or marriage/civil partnership. Family friends or neighbours are not relatives under the Act, though they can still apply with the court's permission.

This matters because relatives have access to a specific permission shortcut that non-relatives do not: the one-year continuous residence route under Section 10(5B).

The Three Permission Routes for Relatives

Unlike parents, relatives do not have an automatic right to file a child arrangements application. You need to satisfy one of these routes before the court will consider your case:

Route 1 — One year's continuous residence (Section 10(5B)): If the child has lived with you continuously for at least one year immediately before you apply, you can file Form C100 without asking the court's permission. The year must be unbroken and run right up to the filing date — there is no grace period. Evidence: school enrollment records, GP registration, Child Benefit records, utility bills showing the same address.

Route 2 — Three-year residence route (Section 10(5)(b)): Any person (relative or not) with whom the child has lived for at least three years can apply without leave if that period began no more than five years before the application and did not end more than three months before filing. The three years do not need to be continuous.

Route 3 — Court permission under Section 10(9): If neither residence route applies, you ask the court for permission to apply. This can be done on Form C100 itself (there is a section for it) or through Form C2 if there are already active proceedings. The court weighs four factors: the nature of your proposed application, your connection with the child, the risk of harmful disruption, and (if the child is looked after by a local authority) the authority's care plan.

There is also a consent shortcut: if every person holding parental responsibility gives written consent to your application, you can apply without leave regardless of residence history.

The Process Once You Have Permission

Whether you qualified automatically or the court granted leave, the substantive application follows the same track:

1. MIAM — attend a Mediation Information and Assessment Meeting with an accredited mediator, or confirm a statutory exemption (domestic abuse, urgency, child protection). The mediator signs your C100.
2. File Form C100 — pay the £270 court fee or apply for Help with Fees (Form EX160). Add Form C1A if there are safeguarding allegations, and Form C8 if your address needs to stay confidential.
3. Cafcass or Cafcass Cymru — the safeguarding service runs police and social care database checks, then phones each party for a safeguarding interview.
4. First Hearing (FHDRA) — the judge reviews the safeguarding report. If everyone agrees, the court can make a final order on the spot. If not, directions are set for further reports or hearings.
5. Section 7 report and further hearings — if needed, Cafcass prepares a welfare report (typically 12–16 weeks). The case may go to a Dispute Resolution Appointment and then a Final Hearing.

Aunts and Uncles — Specific Considerations

Aunts and uncles are relatives under the Act and can use the one-year route. Where practical complications arise:

• An aunt or uncle often steps in suddenly after a crisis — parental addiction, hospitalisation, domestic violence. If the child has been with you for less than a year, you need court permission under Section 10(9).
• The court considers your connection with the child. A close aunt who has been involved in the child's life since birth presents a stronger case than a distant relative meeting the child for the first time.
• If the local authority placed the child with you informally (a "family and friends" arrangement under Section 17), that placement history strengthens both the permission application and the substantive case.

Adult Siblings Applying

An older sibling can apply, but the dynamics are different. The court will examine whether the arrangement serves the child's welfare — particularly where the sibling is relatively young, whether they can provide stable housing and financial support, and whether the arrangement could strain the sibling relationship with the parents.

The one-year residence route applies identically. The permission factors under Section 10(9) focus on the sibling's connection with the child and the quality of care they can provide, not on age alone. A sibling applicant under 18 will generally need a litigation friend to conduct the proceedings, unless the court allows them to conduct the case without one.

Kinship Carers and Legal Rights

"Kinship carer" is not a legal status in itself — it describes a relative or close friend caring for a child outside the formal care system. Without a court order, you have no parental responsibility and limited ability to deal with schools, doctors, and benefits agencies.

A "lives with" child arrangements order gives you shared parental responsibility for the duration of the order. It is the lightest-touch legal route that still provides genuine authority — unlike an SGO, which is heavier but gives overriding PR.

If you are in one of the seven Kinship Zones pilot areas (Bexley, Bolton, Newcastle, Medway, North East Lincolnshire, Thurrock, or Wiltshire), a "lives with" CAO may also qualify you for a non-means-tested financial allowance matching the fostering minimum rate (£176–£309 per week per child in 2026–27, depending on the child's age and area), provided the child meets the "otherwise in care" criteria.

Getting Through the Process Without a Solicitor

Most kinship carers handle the application themselves — solicitor fees of £250–£400 per hour are beyond reach on a fixed pension or low income. The Child Arrangements Order Process Guide covers every step from working out your permission route through to using the sealed order at school and the GP surgery, designed for relatives doing this without legal representation.
