Special Guardianship Order vs Child Arrangements Order

You have been told you need "an order" to formalise a grandchild or niece living with you, and now you are looking at two options: a child arrangements order (CAO) and a special guardianship order (SGO). They sound similar, but the legal weight, the financial support and the practical authority they give you are different enough to shape years of daily life.

Parental Responsibility

This is the core distinction. A "lives with" child arrangements order gives you shared parental responsibility alongside the birth parents. You and the parents hold equal PR, and neither side can override the other without the court's help.

A special guardianship order also gives you PR, but with a critical upgrade: you can exercise it "to the exclusion" of the birth parents. In practice, that means you sign school consent forms, authorise medical treatment and make decisions about the child's upbringing without needing the parents' agreement. The parents still hold PR on paper, but they cannot use it to block your decisions.

Two exceptions apply under an SGO: you cannot change the child's surname or take them abroad for longer than three months without either every PR-holder's written consent or the court's permission.

Duration

A child arrangements order usually runs until the child turns 16 (it can be extended to 18 in exceptional circumstances). A special guardianship order lasts until the child is 18 unless the court discharges it earlier.

How Easy Is It for a Parent to Reverse?

Under a CAO, a birth parent can apply to vary or discharge the order without needing the court's prior permission. Under an SGO, a parent must first apply for leave to bring a discharge application, and the court will only grant leave if the parent can show a significant change of circumstances. That extra hurdle means an SGO provides more long-term stability for the child and the carer.

Financial Support

A child arrangements order does not carry any statutory entitlement to a local authority allowance. You can claim Child Benefit and Universal Credit child elements, and the council may offer discretionary support under Section 17 of the Children Act 1989, but there is no framework specific to CAO holders.

An SGO holder can apply for a means-tested special guardianship allowance from the local authority, benchmarked against the fostering national minimum allowance. Children who were previously looked after may also access the Adoption and Special Guardianship Support Fund for therapeutic services (capped at £3,000 per child per year for 2026/27). And if you meet the pilot's eligibility rules in one of the seven Kinship Zones areas, you receive the full fostering allowance with no means test.

Court Process

Both orders are applied for in the Family Court. A CAO uses Form C100; an SGO uses Form C1 plus the supplementary Form C13A. The SGO also requires three months' written notice to the local authority before you can file, and the council must carry out a full home assessment and produce a report for the court. A CAO does not trigger that statutory assessment.

The SGO process is longer — roughly six to eight months for a private application — but the stronger legal footing and financial support that come with it are why many kinship carers choose it over a CAO.

Which One Is Right?

If the arrangement is likely to be short-term, the parents are cooperative, and you do not need exclusive decision-making authority, a child arrangements order may be enough. If you need long-term stability, the ability to make decisions without parental interference, and access to local authority financial support, a special guardianship order is the stronger option.
