A foster carer cannot change a foster child’s name on their own. A child in foster care is a “looked-after child”, and foster carers do not hold parental responsibility (PR). Changing a looked-after child’s first name or surname needs the agreement of everyone with PR - usually the birth parents and, where there is a care order, the local authority - and in many cases the written permission of the court. These safeguards exist to protect the child’s legal identity and their link to their birth family while they are in care.
Why foster carers can’t simply change a child’s name
The single most important point is this: foster carers are not the child’s legal parents and almost never have parental responsibility for the children they look after. Parental responsibility is the bundle of legal rights and duties a parent has - and the legal authority to change a child’s name sits squarely inside it.
When a child is fostered through a council or an agency, PR is shared in one of two ways:
- Voluntary arrangements (accommodation under section 20 of the Children Act 1989). The birth parents keep full parental responsibility. The local authority has no PR at all - it is simply providing somewhere for the child to live with the parents’ agreement. The parents must consent to any name change.
- Care orders (section 31 of the Children Act 1989). The local authority shares parental responsibility with the birth parents. Even then, the council cannot change a looked-after child’s surname without the written consent of every person with PR or the leave of the court - a restriction written directly into section 33(7) of the Act.
In neither situation does the foster carer hold PR, so a foster carer cannot sign a deed poll for the child, instruct a deed poll service, or update the child’s name with a school, GP or passport office. Doing so without authority could be challenged and unwound.
The law that protects a looked-after child’s name
The key protection is section 33(7) of the Children Act 1989, which says that while a care order is in force, no person may cause the child to be known by a new surname without either the written consent of everyone with parental responsibility or the permission of the court. A similar bar applies to removing the child from the UK.
Courts have consistently treated a child’s name as a significant part of their identity, not an administrative detail. A surname links a child to their birth family, heritage and history - ties that the care system is designed to preserve wherever it is safe to do so. That is why even a local authority with a care order cannot change a name on its own say-so.
The proper process: who has to agree
If there is a genuine reason to change a looked-after child’s name, the request follows a clear chain of consent rather than a quick form. In practice that means:
- The child’s social worker and the local authority first. Any proposal is discussed within the child’s care planning, not arranged privately by the carer.
- Everyone with parental responsibility. This normally includes both birth parents (where each has PR) and the local authority if there is a care order. All of them must agree in writing.
- The court, where consent is missing or the change is contested. If a parent objects, or no one is sure consent is valid, the matter goes to the family court for a decision.
Throughout, the test the court applies is the welfare principle in section 1 of the Children Act 1989: the child’s best interests come first, above the wishes of any adult.
When a court will get involved
Where agreement can’t be reached, the decision is taken out of everyone’s hands and given to a judge. The usual route is an application for a specific issue order (or, occasionally, a prohibited steps order to stop a change). The court weighs factors such as:
- The reasons for wanting the change and whether they are about the child’s welfare or an adult’s preference;
- The child’s own wishes and feelings, given more weight as they get older;
- The importance of maintaining the child’s identity and links with their birth family;
- Any safeguarding concerns, such as a child needing to be untraceable to someone who poses a risk.
Genuine safety risks are one of the few situations where a court may agree to change - or temporarily mask - a looked-after child’s name. These cases are handled carefully and specifically, never as a routine request.
What foster carers can and can’t do day to day
Foster carers do an enormous amount for the children in their care, but the law draws firm lines around identity:
- Allowed: using a child’s preferred first name informally at home or school, with the agreement of the social worker and those with PR - this is not a legal name change.
- Not allowed: signing a deed poll, applying to change the child’s name on their passport or official records, or arranging a name change without the local authority and everyone with PR agreeing (and the court’s permission where a care order applies).
If a foster placement later becomes permanent through a different legal order, the picture can change. Under a special guardianship order the special guardian gains enhanced PR but still cannot change the child’s surname without the consent of everyone with PR or the court’s leave. Where a child is adopted, the legal position is different again - we cover that in our guide to changing a child’s name after adoption.
Children aged 16 and over in foster care
The position shifts when a young person reaches 16. In England and Wales, a young person aged 16 or 17 can generally change their own name and sign their own deed poll without needing a parent’s consent. A looked-after 16- or 17-year-old can therefore apply for a deed poll in their own right.
That said, anyone in care should still speak to their social worker first, because their name may appear on care plans, school records and other documents the local authority manages. If you’re a young adult ready to make it official, our adult deed poll service handles the paperwork properly. For under-16s, a name change is only possible through the consent-and-court process above - never by a carer acting alone.
If you are entitled to change the child’s name
Once the proper consents (and any court permission) are in place - for example where a parent with PR is making the change with the local authority’s agreement, or after a court order - the document itself is straightforward. A professionally printed unenrolled deed poll is legally valid and accepted by HM Passport Office, the DVLA, the NHS, banks and schools, and our child deed poll service starts from £14.49 with same-day dispatch before 3pm. If the dispute is over whether the change should happen, the court route is the right next step - see deed poll versus court order for a child’s name change.
Frequently Asked Questions
Can a foster carer change a foster child’s surname?
No. Foster carers do not have parental responsibility, so they cannot change a looked-after child’s surname. It requires the consent of everyone with PR - the birth parents and, where there is a care order, the local authority - and the court’s permission if anyone disagrees or a care order is in force.
Does the local authority need the birth parents’ consent?
Yes. Even with a care order, section 33(7) of the Children Act 1989 stops the local authority changing a child’s surname without the written consent of every person with parental responsibility or the leave of the court.
Can a foster child’s name be changed for safety reasons?
Sometimes. Where a child faces a genuine safeguarding risk, a court may agree to change or temporarily mask their name to keep them safe. These decisions are made by a judge under the welfare test, case by case, and never arranged informally.
Can a 16-year-old in foster care change their own name?
Generally yes. A young person aged 16 or 17 can usually change their own name and sign their own deed poll without parental consent. They should still tell their social worker, as their name appears on care records the local authority manages.
Is using a different first name at home a legal name change?
No. Calling a child by a preferred first name informally - with the social worker’s and PR-holders’ agreement - is not a legal change. It doesn’t alter passports, NHS records or official documents, which still show the registered name.
