Introduction

A child connects their identity to their name. It indicates who their family are, their cultural heritage, their ancestry and their history.

Sociologist Erving Goffman says

Persons invest self feelings in their possessions. Perhaps the most significant of these possessions is not physical at all [but] one’s full name. Whatever one is called thereafter, loss of one’s name can be a great curtailment of self.

In the UK and many other countries it’s still common for children to have their father’s surname even though double-barrelled names are becoming more prevalent and some children bear their mother’s surname too.

But the `default’ it seems is for a child to have dad’s surname – taking place without discussion or thought. It’s just the way it’s done.

The law doesn’t require this to happen. Parents can register a child with any surname they choose, including a double-barrelled one.

Keep one thing in mind as you read this. It applies only to children under 16—or under 18 in rare cases. Once someone reaches that age, they’re no longer covered by the Children Act. They’re legally an adult, and these rules no longer apply.

My ex has changed my daughter’s surname Dave told me. I’d never met him but he’d called me a few times over the last year. He didn’t have parental responsibilty for her and her mum had whittled away his bond with her as he did nothing because he was too scared to `rock the boat’. She’d unilaterally reduced his time with his daughter, moved onto deciding he could only see his little girl supervised. It ended with him seeing his daughter’s surname changed to her new partner’s – which she did because she wanted the girl to be `part of a family’…which obviously didn’t include him.

I’ve seen people make the case for and against a name change – and it’s heartbreaking. A name is more than just a name – it’s a connection to family, heritage and being part of something bigger than yourself. It’s history, togetherness and an important bond.

Who can change a child’s surname?

If everyone with parental responsibility for a child agrees to change the child’s surname, they can make that change. If not, a court must order it.

It’s as simple as that.

There are no other circumstances whatsoever, including residence orders, etc. that allow for this. The key factor here is that, unless a court order says otherwise, everyone with parental responsibility must be consulted.

Children can have a `known as’ name, but the real name does need to be acknowledged and official documents will likely continue to be issued in the name of the child’s birth certificate.

In terms of schools and other statutory agencies guidance is provided concerning this. In schools, for example, guidance is to change a child’s name on the school roll without proper evidence. The school must see proof—independent of the requesting parent—that the other parent agrees.

Why do people want to change their child’s surname?

There are many reasons people want to change their child’s surnames. As always, their motives may be good or bad. They may focus on the child, or they may not. Every case is likely to have long-term implications that need careful thought.

These reasons include wanting:

1. To distance a child from a partner perceived as abusive, useless or absent.
2. A child to have a surname as family members of the primary carer – half-siblings, step parents and others.
3. To punish an ex-partner.
4. To give a child a more `typical’ name of the culture they live in.

The main motivation for wanting to do this should be purely based on the best interests of the child. Changing a surname is a big step, and you shouldn’t take it lightly.

The case for changing surnames

There is case law for and against doing this. If you’re interested in this section of the blog, you’re probably looking for the former rather than the latter.

A prominent case, often cited is Re W, Re A, Re B (Change of Name) [1999] 2 FLR 930. This case, heard in the Court of Appeal can be summed up as follows:

This case clarified that the court can permit a change of a child’s surname if it is in the child’s best interests – even if one parent objects. The court must consider:

• The welfare checklist under Section 1 of the Children Act 1989

• The importance of the child’s identity and connection to both parents

• Whether the current or proposed name will affect the child’s sense of stability

The court recognised that sometimes a name change may help promote the child’s welfare — for example, in blended families or when one surname causes distress.

It can be upsetting and uncomfortable for a child to have a different surname to everyone else around them – mum, half-siblings, stepfather, etc. – leaving them feeing isolated from everyone else. This is perhaps even more the case if a child doesn’t have a relationship and/or time with the parent whose name they share.

Even more so if the parent has committed a crime with a shared surname providing an unwanted link between a child and a parent.

It can cause upset at school where other children may ask why they don’t share a surname with half-siblings or their own mother. It can cause problems at airports with border control asking why a mother is travelling with a child she doesn’t share a surname with, causing additional complications and paperwork.

The case against changing surnames

Names are important. In a typical scenario when a child’s parents have separated mothers usually become primary carers. In this situation the child’s surname remains a significant link to his/her father’s family. It can also means a lot in terms of culture, religion, heritage, ancestry and history.

Furthermore, if you want to change the child’s surname to that of a new spouse so everyone has the same name…what happens if you separate from that new spouse? Your child could face another name change. Or they might keep the current name and end up with one their mother no longer uses—and one with no connection to their biological father either.

The above scenario makes another name change more likely.

A common justification used by parents wanting to change the name of their child is that they feel `uncomfortable’ with their children having the surname of an ex partner they are no longer on good terms with or dislike – but there is an argument against it. Ward LJ said on appeal in Re C (Change of Surname):

The unhappy fact is in the light of which these applications, in this day and age, have to be judged is sadly quite different. The breakdown in relationships is now of such a magnitude that there is nothing at all unusual in children having names different from their mother.

For this side of the argument there is case law against too. Again, it was heard in the Court of Appeal:

Case: Re C (Change of Surname) [1998] 1 FLR 323

Summary:
In this case, the court refused the mother’s application to change her child’s surname to that of her new husband. It found:

• The child had always been known by the father’s surname

• Changing it would undermine the child’s relationship with the father

• A surname is an essential part of a child’s identity, not just a matter of parental preference

Key takeaway: The court ruled that continuity and the importance of maintaining links with both parents outweighed the desire to reflect a new family structure through a name change.

With this in mind you’re going to have to convince a child that not making an order that you wish will cause harm – saying you feel uncomfortable, etc. is unlikely to hold much weight in a hearing.

Can I change my child’s surname – how to do it.

If everyone who has PR for your child agrees on a new surname, it’s easy.

It’s best to get the agreement in writing. You’ll need it if you want to apply for a passport in the child’s new name. Statutory agencies (schools, the NHS, the Passport Agency, the police, social services, etc.) have guidance and should seek the consent of all holders of PR for the child before amending their records.

The second way of doing it is getting a court order (see reasons for and against above). The application would be a Specific Issues Order, using a C100 form. At a hearing about this, you must show why what you’re asking for is in your child’s best interests. You also need to explain what harm your child may face if the court doesn’t make the order you’re seeking.

Can I use a deed poll to change my child’s surname?

Sort of. A deed poll agency will happily give you a certificate with whichever name you like for your child however – but it will not have any legal standing and does not overrule the law. In law, your child’s name will remain the same as it did before you obtained the certificate and you won’t be able to use it to change names with statutory agencies (see above!)

A good example would be passports.

The Passport Agency (a statutory agency) will by default issue passports with the name on the holder’s birth certificate. A deed poll can be accepted as a valid name change for a child, but only if all holders of parental responsibility give written consent. It’s also accepted if the deed poll confirms this consent or if a court order approves the change.

The upshot of this is that with a deed poll or not you still need the permission of all holders of PR to consent or else a court order.

What legal powers do deed polls have?

Deed polls on their own have no legal weight for a child. When someone is over 16 years old however, the situation changes dramatically. Adults can call themselves whatever they like, as long as they’re not doing it for fraudulent purposes. It is permissible for adults to use whatever names they like, but statutory agencies will want to see evidence of some kind – a deed poll, a statutory declaration or an affidavit with evidence of previous name changes you’ve made and evidence that you’re using the new name.

Businesses may be different. Banks for example are able – depending on their own policies – to issue or refuse to setup a bank account with a particular name on their own criteria. This is true for both adults and children, although it is typical for passports, etc. used to verify identity as part of the setup process.

People do this and may go unchallenged—especially if agencies ignore the guidelines or other holders of parental responsibility don’t act.

What do I do if my ex has changed my child’s surname?

A deed poll isn’t a legal document. It’s not an order or an agreement. It’s a declaration. If it names your child, it’s your ex’s declaration—not your child’s. Companies issue deed polls, not courts.

Many people feel impressed by an official-looking document. Many organisations do too. Don’t let it fool you into believing it’s more than it is.

It is important to keep your eyes open. A partner who has changed the name of a child without the consent of other holders of PR is often reluctant to broadcast the news – with the other parent finding out when they speak to the school, doctor or have seen documents with their child’s (new) name on it.

Children can use a ‘known as’ name, but everyone must acknowledge their legal name—the one on their birth certificate. What ‘acknowledged’ means, though, is open to interpretation.

Authorities should issue passports and similar documents only in the name on your child’s birth certificate. The Passport Office will ask for proof of your child’s name and written consent from all other holders of parental responsibility before issuing a passport in a different name.

If you have noticed a document that has the incorrect name on your child, address it as soon as possible.

How do I change my child’s name back?

A common argument about changing a name back is that a child has gotten used to using the new name and doing so would represent further unneeded disruption. This argument might hold weight in a court arena. It will also likely be said that your inaction demonstrates your lack of involvement with your child’s life.

Acting quickly weakens this argument

So if your child’s name has been changed – act as soon as possible, Possible courses of action include:

1. Contact the agency, school, etc. and advise them what the correct name is, asking them to change it to the correct one.
2. Tell your ex-partner what has happened and ask them to use your child’s correct name.
3. Address the issue in court if you have a case running.
4. A Specific Issues Order application to change your child’s name back.

What are the long term implications of changing my child’s surname?

Changing a child’s name can have long term implications. It can cause confusion, upset and questions about identity. An adult who sees their birth certificate not matching the name they’ve used for a large part of their life can feel disorientated by it. They may face problems when they apply for a passport, get married, or confront old conflicts between their parents and painful memories.
