Part of: Child Custody Specialists

Smacking law in the UK depends on where the smack happens. In England, a parent accused of common assault can still argue that a smack was “reasonable punishment”. In Wales and Scotland that defence no longer exists, so any smack can be an assault. If a school, a social worker or your child’s other parent has raised a smack, they will be asking about your child’s safety as much as about the criminal law. This guide explains the law in England and Wales, what social services look at after a referral, and how the family court weighs a smack in a dispute over child arrangements.

Key takeaways

  • England keeps a narrow defence. Reasonable punishment cannot justify a battery charged as wounding, grievous or actual bodily harm, child cruelty or strangulation (Children Act 2004, s.58). It survives only for common assault.
  • Wales removed it on 21 March 2022. No one can justify physical punishment of a child in Wales as reasonable punishment, in a civil or a criminal case (Children (Abolition of Defence of Reasonable Punishment) (Wales) Act 2020, s.1).
  • The place decides, not your address. Both laws turn on where the smack took place, so a family living near the border can be under two sets of rules.
  • A mark changes the picture. Prosecution guidance treats an injury that is more than “transient and trifling” as capable of being actual bodily harm, where the defence does not apply.
  • Social services and the family court ask a different question. They look at harm to your child, not only at whether anyone broke the criminal law.

If someone has reported a smack, book a free initial consultation and one of our specialists will give you initial advice before your next conversation with a social worker or the other parent.

Is smacking illegal? UK law, nation by nation

Smacking a child is unlawful in Wales and Scotland. In England it can be lawful, but only within the limits of the reasonable punishment defence. Northern Ireland has its own version of the English rule. Each nation of the UK sets its own smacking law, and the answer turns on where the smack happened.

Scotland’s Act ended the rule that physical punishment by a parent was justifiable and therefore not an assault (Children (Equal Protection from Assault) (Scotland) Act 2019, s.1). Our guidance covers smacking law in England and Wales, not the rest of the UK.

Smacking law in England: what reasonable punishment means

Reasonable punishment is a defence a parent raises in court after a charge, and section 58 lists the offences where it can never apply: wounding and grievous bodily harm, assault occasioning actual bodily harm, cruelty to a child under 16, and, since June 2022, strangulation or suffocation. In a civil claim, a parent cannot justify a battery that causes actual bodily harm to a child as reasonable punishment either (s.58(3)).

That leaves common assault and battery. The Crown Prosecution Service’s charging guidance says the defence is available there to parents and adults acting in their place. It also tells prosecutors that where the victim is a child, they may charge actual bodily harm for an injury that would usually count as common assault, unless the injury was merely transient and trifling. Its examples are a black eye on one side of the line and temporary reddening of the skin on the other.

Even then, the punishment has to be moderate and reasonable. The guidance lists the factors a court weighs:

  • what the adult did, and the context;
  • how long it went on;
  • the physical and mental consequences for the child;
  • how old the child is, and their personal characteristics;
  • the reasons the adult gives.

What changed in Welsh smacking law on 21 March 2022?

Wales abolished the common law defence of reasonable punishment for any physical punishment of a child there. The Act defines corporal punishment as any battery carried out as a punishment (s.1(4)), so the Act covers a light smack on the hand. It also amended section 58 so that the English defence applies only to a smack taking place in England. Section 1 came into force two years after Royal Assent, on 21 March 2022 (s.5(2)).

The Welsh Government’s announcement says the smacking ban Wales introduced applies to everybody in Wales, visitors included (GOV.WALES, 21 March 2022). Its guidance for practitioners adds three points parents ask about:

  • There is no new offence. The police treat a smack as an assault, as they would an assault on an adult.
  • Everyday handling is not punishment. The Act does not stop you holding a child to keep them from harm, or helping with dressing and washing.
  • Prosecution is not the first aim. The police could arrest and charge a parent, leading to a criminal record, but the stated preference is advice and support. Where the police think it appropriate, an out-of-court disposal can come with support to prevent it happening again.

Based on the Children Act 2004, s.58, the Children (Abolition of Defence of Reasonable Punishment) (Wales) Act 2020, the Children Act 1989, ss.1, 11 and 47, and the Crown Prosecution Service charging guidance. Only a court decides whether a punishment was reasonable.

What social services look at after a smacking referral

They look at harm to your child, whether or not the smack was lawful. A council must make enquiries when it has reasonable cause to suspect that a child in its area is suffering, or is likely to suffer, significant harm (Children Act 1989, s.47). Harm means ill-treatment or the impairment of a child’s health or development, and ill-treatment includes forms that are not physical (s.31(9)). A referral is often the first a parent hears of it, usually after a child says something at school.

In practice the questions are about the pattern, any injury, what your child has said, and how you respond to the concern. A single smack that a parent explains honestly reads very differently from a pattern that the parent denies. In England, a smack that might fall within the reasonable punishment defence can still prompt questions about your child’s welfare. Our guide to a social services investigation walks through each stage, and our guide to the section 47 report explains what the enquiry produces.

A social worker may ask you to agree that your child stays with a relative or elsewhere while enquiries continue. That agreement is voluntary, and our guide to section 20 and voluntary accommodation explains what you can say yes or no to before you sign anything.

Can a smack affect child arrangements?

Yes, because the family court must consider any harm a child has suffered or is at risk of suffering when it decides a disputed child arrangements application (Children Act 1989, s.1(3)(e)). Your child’s welfare is the court’s paramount consideration. That is a wider question than the criminal law asks, so the reasonable punishment defence does not settle it.

Arguments about smacking in contact disputes usually run one of two ways. One parent says the other smacks during their time, or a parent raises an old smack to argue for less time. In either case the court can attach conditions to an order (s.11(7)), so a disagreement about discipline does not have to decide where your child lives. Where a parent says the children are at risk of harm, the court expects that concern in writing on the C1A form.

We assisted a mother whose former partner raised a smack, given at the end of a difficult day more than a year earlier, to argue that their son should stop staying overnight with her. She had been ready to deny it. Instead, we helped her set out what happened, what she had done since, and the parenting support she had already sought, so the court had her account before the first hearing. Every case turns on its own facts.

After someone reports a smack: your first week

  1. Write down what happened. While it is fresh, note the date, what led up to it, where it happened and whether it left a mark. Where it happened matters, because UK smacking law differs between England and Wales.
  2. Do not refuse to engage. Social workers record how a parent responds. They can read silence or anger as a lack of insight, even when it comes from fear.
  3. Be honest about the smack, and specific. Neither inflate it nor minimise it. Explain what you do now instead, and any parenting support you have asked for.
  4. Keep your child out of it. Do not ask your child what they told the school or coach them on what to say.
  5. Take advice before any meeting or agreement. A child protection conference or a written agreement can shape everything that follows.

Expert Tip

After a smacking referral, what helps a parent most is being able to say, in the first conversation, what happened, why it will not happen again and what they now do instead. Social workers and judges are listening for insight. “It was only a smack” tends to close that conversation down. “I lost my temper, and this is what I do differently now” keeps it open.

Smacking law UK: frequently asked questions

Is smacking illegal in the UK?

UK smacking law differs by nation. Smacking is unlawful in Wales and Scotland. In England, a parent charged with common assault or battery can argue the smack was reasonable punishment (Children Act 2004, s.58), but not against a charge of actual bodily harm, wounding, child cruelty or strangulation. The court decides whether a smack was reasonable.

Can I smack my child in Wales if we are only visiting?

No. The Welsh Government says the law applies to everybody in Wales, including visitors, from 21 March 2022. The Act turns on where the punishment takes place, not on where the family lives, so the law reaches an English family on holiday in Wales.

What counts as reasonable punishment?

There is no fixed list. Prosecution guidance says a court weighs the nature and context of what happened, how long it went on, its physical and mental effect on the child, the child’s age and characteristics, and the adult’s reasons. An injury beyond temporary reddening can take it outside the defence altogether.

Will social services take my child away for smacking?

A court can only make a care order if it finds the child is suffering, or likely to suffer, significant harm attributable to the care they receive (Children Act 1989, s.31(2)). Social services enquiries start at a lower point, with reasonable cause to suspect significant harm, so take any referral seriously and get advice early.

Can my ex stop contact because I smacked our child?

Not on their own say-so. If you cannot agree the arrangements, the court decides, and it must consider any harm your child has suffered or is at risk of suffering. It can attach conditions to an order rather than reduce time, and it will look at what has changed since. Our guide to what courts weigh before stopping contact sets out the other grounds they consider.

Does the smacking law cover grandparents and babysitters?

In Wales, yes: the Act covers physical punishment of a child by anyone. In England, the prosecution guidance describes the reasonable punishment defence as available to parents and to adults acting in their place, such as a relative looking after the child.

Someone has reported a smack. What you say next matters

Two things go wrong after a smacking referral. A frightened parent denies or minimises the smack in the first conversation, and that account follows the family into every later meeting. Or the parent agrees to an arrangement for their child, without advice, that is hard to undo. In a contact dispute, the other parent can use the same smack to argue for less time unless you set out your side early and calmly.

A free initial consultation is a conversation with a specialist, who gives you initial advice tailored to your circumstances. It does not include drafting or reviewing documents. If you can, have any letter from social services or the court to hand, and the date of the smack.
