The home and property

Two things get said about the law and your home, and they can't both be true. One is that your home is your castle and you can do anything to someone who breaks in. The other is that you'll be prosecuted for defending yourself against a burglar. Neither is what the law says. This lesson takes lesson 13's questions (a need for force, force in proportion, a threat happening now, and your belief) and asks what changes when the threat comes through your own window, and what changes when the only thing at risk is your property. It covers England and Wales, Scotland, the Model Penal Code and three US states, and like lesson 13 it tells you the questions a court asks, not the answer in your own case.

As in lesson 13, every section here that states a legal rule opens with the same sentence, and it follows each table: this is general information, not legal advice. The law differs by state, and between England and Wales, Scotland and Northern Ireland. Lesson 13 explained statute citations, the Model Penal Code (a model, not law anywhere by itself) and "deadly force"; this lesson builds on them.

Before any law: the phone

Lesson 5, "Home, the door and the doorstep", gave the advice of the two sources this course read on hearing someone inside: call the police, and don't go and look. The householders' leaflet for England and Wales starts the same way: "Wherever possible you should call the police."³ Lesson 5 labelled that advice sensible and untested, and the label stands.

Everything below is about the moment when that isn't possible, or wasn't enough. That moment is here because the law asks about it afterwards, not because anyone who ends up face to face with an intruder did something wrong. As lesson 5 said, the burglar made that moment.

The householder rule in England and Wales

This is general information, not legal advice. The law differs by state, and between England and Wales, Scotland and Northern Ireland.

Lesson 13 gave the ordinary rule. Under section 76 of the Criminal Justice and Immigration Act 2008, force is not reasonable "if it was disproportionate in those circumstances" (s.76(6)), judged on the circumstances as the defendant believed them to be. In 2013 Parliament added a different line for one kind of case. In a householder case, force is not reasonable "if it was grossly disproportionate in those circumstances" (s.76(5A)).¹ The CPS notes the change came into force on 25 April 2013 and does not reach back to force used before then.²

Section 76 itself says this line is new. Apart from its different provision for householder cases, the section "is intended to clarify the operation of the existing defences" (s.76(9)).¹ On the section's own account, then, the rest clarifies the existing law, and the householder line was Parliament's new choice. Why the home? The Crown Prosecution Service's legal guidance, which this course read in an archived copy from July 2024, reports the Government's reason: the threat from an intruder is most immediate when he is entering or has entered someone's home, so the heightened defence is kept to those cases.² The CPS also reports that the High Court, hearing a challenge to the rule, found it compatible with the state's duty under the European Convention on Human Rights to protect the right to life.² Whether the home should get this extra room is a value question, and this course describes Parliament's answer without taking a side on it. The reasons given here are the Government's and the court's. This course read no source that argues against the rule, only the CPS's report that it was challenged, so the case against it is not set out on this page.

What R v Ray settled

A few years after the change, an appeal argued exactly that: force that isn't grossly disproportionate must be reasonable. The Court of Appeal, the court above the trial court, disagreed in R v Ray (2017); in a case name, R stands for the Crown, which brings the prosecution. This course did not read the judgment, so what follows is the CPS guidance's summary.² The effect of s.76(5A), the court said, was narrow. A jury in a householder case asks two questions, in order:

1. Was the force grossly disproportionate, in the circumstances as the householder believed them to be? If it was, it wasn't reasonable, and self-defence fails.
2. If it wasn't, was it reasonable in all the circumstances as the householder believed them to be?

In the CPS's words: "Disproportionate force which was short of grossly disproportionate was not, on the wording of s.76 (5A), of itself the use of reasonable force."² So the rule does not create a zone where anything short of grossly disproportionate is automatically fine. What it does is take grossly disproportionate force off the table, and leave a jury free to find force reasonable in a home that it might have called disproportionate on a street.

The CPS summary also passes on what the Court of Appeal said a judge might put to a jury about the householder's position. Among the circumstances: the shock of coming upon an intruder, the time of day, whether other help was there, the wish to protect the home and the people in it, how vulnerable they were (children especially), picking up an object such as a knife or a stick that would lawfully be to hand in a home, and the intruder's conduct.² Put that beside lesson 13's section 76(7), that a person "may not be able to weigh to a nicety the exact measure of any necessary action", and you have this course's reading of how the two fit together: in the home, the law gives more room where the situation gives less room to think.¹ That is an account of the rule, not an argument for it, and it is this course's, not Parliament's or the court's.

Four conditions, and where the rule stops

A case is a householder case only if all four of the conditions in s.76(8A) are met.¹ In them, V is the statute's letter for the other person, and a trespasser, in plain terms, is someone in a place without any right or permission to be there.

Condition (d) turns on believing the other person to be a trespasser. This course read nothing on how that applies to force against someone who lives in the home, such as a partner, so it gives no answer on that. Outside a householder case, lesson 13's ordinary rule applies, that force is not reasonable if it was disproportionate, and lesson 7, "Domestic abuse and stalking", has the lines for someone frightened of a person they live with.¹

This is general information, not legal advice. The law differs by state, and between England and Wales, Scotland and Northern Ireland.

One extension matters for real homes, and so does one limit. Someone who lives above their shop, with an inside way between the two, is covered in the shop as well (s.76(8B)); the CPS adds that customers or acquaintances in the shop are not, unless they live there too.¹² And the whole rule is England and Wales's. Section 76 extends to Northern Ireland, but the householder subsections were added for England and Wales (and for service offences, those under military law), so Northern Ireland is different again, and this course read nothing on how its courts treat force in a home.¹

What the householders' leaflet adds

The Crown Prosecution Service and the National Police Chiefs' Council wrote the leaflet for the public in England and Wales, revised in 2018. It's three short pages, and it answers the questions people actually ask.³

• Using what's to hand. "This is still the case if you use something to hand as a weapon": the protection for doing what you honestly and instinctively believed necessary doesn't vanish because you picked something up.
• Fear counts. "As a general rule, the more extreme the circumstances and the fear felt, the more force you can lawfully use in self-defence."
• Disproportionate isn't automatically unlawful at home. "The force you use must always be reasonable in the circumstances as you believe them to be." But where you're defending yourself or others from intruders in your home, "it might still be reasonable in the circumstances for you to use a degree of force that is subsequently considered to be disproportionate", perhaps in extreme circumstances in the heat of the moment. "The law will give you the benefit of the doubt in these circumstances."
• Not waiting. "Do I have to wait to be attacked? No, not if you are in your own home and in fear for yourself or others."
• Where it tips over. "If for example you had knocked an intruder unconscious and then went on to kick and punch them repeatedly such an action would be more likely to be considered grossly disproportionate." The leaflet names two cases that could be prosecuted: going on to hurt or kill someone already knocked unconscious, to punish them, and where "you knew of an intended intruder and set a trap to hurt or to kill them rather than involve the police".
• Afterwards. "the police have a duty to investigate incidents involving a death or injury". In some cases, such as where the facts are very clear or the injuries less serious, the investigation "will be concluded very quickly, without any need for arrest", and the leaflet adds that "It is a fact that very few householders have ever been prosecuted for actions resulting from the use of force against intruders." The leaflet gives no number, and this course does not supply one.

GOV.UK's page "Using reasonable force against intruders", from the Home Office and the Ministry of Justice, says the same more briefly ("You do not have to wait to be attacked before defending yourself in your home"), names no nation, and points readers to the Crown Prosecution Service's guidance.⁴

Scotland: no special rule for the home

This is general information, not legal advice. The law differs by state, and between England and Wales, Scotland and Northern Ireland.

Scotland has no householder rule. Section 76 does not apply there, and the Judicial Institute for Scotland's Jury Manual has no rule for householders in its self-defence chapter, which this course read in full.⁵ An intruder in a Scottish home is judged by the questions lesson 13 set out for anywhere else in Scotland: was the accused in imminent danger, believed on reasonable grounds; was there any "cruel excess"; and was there a reasonable means of escape?

The manual does not set the escape question aside at home. Two things it says matter in a house at night: the escape has to be one the accused "can reasonably be expected to adopt", and when someone is defending another person, escape does not arise at all.⁵ Whether a Scottish court treats escape from your own home differently from escape from a street, the manual does not say, and this course read no case on it.

Castle doctrine in the US

This is general information, not legal advice. The law differs by state, and between England and Wales, Scotland and Northern Ireland.

The US name for the special treatment of the home is castle doctrine. The National Conference of State Legislatures, which serves legislators of both parties, describes the common-law principle as the right "to use reasonable force, including deadly force, to protect themselves against an intruder in their home".¹⁰ Lesson 13 showed the duty to retreat outside the home; this is the inside, and the texts put it in different ways.

The Model Penal Code keeps its duty to retreat before deadly force, with an exception: "the actor is not obliged to retreat from his dwelling or place of work, unless he was the initial aggressor" (§3.04(2)(b)(ii)(A)). At work, the same clause keeps the duty when the attacker is someone the actor knows works there too. A dwelling is whatever is for the time being the person's home or place of lodging (§3.11(3)).⁶ The rest of §3.04 still applies at home, including its list of what deadly force may be used against: death, serious bodily injury, kidnapping or sexual intercourse compelled by force or threat.

New York has two rules that reach the home. Its retreat duty before deadly force does not apply to someone "in his or her dwelling and not the initial aggressor" (§35.15(2)(a)(i)).⁷ And a separate section, §35.20, which §35.15(2)(c) points to, lets a person in possession or control of a dwelling, or licensed or privileged to be in it, use deadly physical force when they reasonably believe it necessary to prevent or end a burglary of it, with no retreat clause.⁷ What counts as a burglary or a dwelling there is defined in parts of the code this course did not read.

Florida says a person in a dwelling or residence where they have a right to be has no duty to retreat (§776.013(1)), and then adds a presumption, a rule that once certain facts are shown, another fact is taken as established. A person is presumed to have held a "reasonable fear of imminent peril of death or great bodily harm" when using force that could kill or badly injure someone. The facts that bring it in: the other person was "in the process of unlawfully and forcefully entering, or had unlawfully and forcibly entered, a dwelling, residence, or occupied vehicle", or had removed or was trying to remove someone from one against their will, and the person using force knew or had reason to believe it was happening or had happened (§776.013(2)).⁸ The statute lists four cases where the presumption does not apply, and the first matters most here: it does not apply against someone who has a right to be there, such as an owner or a tenant, unless an injunction for protection from domestic violence or a written pretrial supervision order of no contact is in place against them (§776.013(3)(a)).⁸ If someone you live with is frightening you, the lesson "Domestic abuse and stalking" starts with the helplines.

Texas has a presumption of the same kind. A person's belief that deadly force was immediately necessary is presumed reasonable if they knew or had reason to believe one of three things: the other person had unlawfully and with force entered, or was trying to enter, their occupied habitation, vehicle, or place of business or employment; had dragged them out of one, or was trying to; or was committing one of a list of violent crimes, robbery among them. Two more conditions apply: they did not provoke the other person, and they were not engaged in criminal activity beyond a minor traffic offence (§9.32(b)).⁹ For someone who has a right to be there, did not provoke it and is not engaged in criminal activity, the fact-finder "may not consider whether the actor failed to retreat" (§9.32(c) and (d)).⁹

This is general information, not legal advice. The law differs by state, and between England and Wales, Scotland and Northern Ireland.

How far the home should change these questions, and whether presumptions like Florida's and Texas's go too far or not far enough, is a value question too. This course describes the statutes without taking a side, and lesson 13 set out the arguments on stand your ground in each side's words.

Two things are easy to miss in that table, and both are this course's reading of the texts. A presumption is not a licence: it goes to whether the fear or belief was reasonable, and the rest of each section still applies; this course did not read how courts apply or displace these presumptions beyond the exceptions the statutes list. And every row still asks whether the defender believed force, or deadly force, was needed.

Joanne at 2am

This is general information, not legal advice. The law differs by state, and between England and Wales, Scotland and Northern Ireland. What follows asks which questions a court would ask, and gives no verdict.

Joanne lives alone in a terraced house in Shrewsbury. At 2am she's woken by a noise downstairs, and from the top of the stairs she can hear someone climbing in through the kitchen window.

The first thing the sources say is the phone. The leaflet: "Wherever possible you should call the police."³ The Suzy Lamplugh Trust, the other source lesson 5 read, adds: don't go and investigate on your own. She calls 999 from the landing.

Now suppose the man comes up the stairs towards her before the police arrive, and she swings the heavy bedside lamp she's holding at him as he reaches the top.

In England and Wales, where Shrewsbury is:

• Is it a householder case? On these facts she is defending herself, not property, in her own house, where she is not a trespasser. Did she believe he was a trespasser? The window at 2am bears on that, and it's her belief that counts.¹
• Grossly disproportionate? That's the jury's first question, and the leaflet's example of kicking an unconscious intruder shows the kind of thing it's about.³
• If not, reasonable? Judged as she believed things were. The circumstances the Court of Appeal mentioned, as the CPS summarises them, are all here: the shock, the hour, nobody else in the house, an object to hand.² Section 76(7) asks the jury to take into account that someone acting for a legitimate purpose "may not be able to weigh to a nicety the exact measure of any necessary action".¹
• Did she have to wait? The leaflet's answer to "Do I have to wait to be attacked?" is "No, not if you are in your own home and in fear for yourself or others".³

In Scotland, if the same house were in Dumfries:

• Imminent danger, believed on reasonable grounds? A stranger coming up the stairs at her at night after breaking in is the kind of fact that question is about.⁵
• Cruel excess? Was there any "cruel excess" of violence in her swing, against what she faced?⁵
• A reasonable means of escape? Was there one she could reasonably be expected to take, from the top of her own stairs at 2am? No special rule for the home changes the question, though the facts of a home at night bear on the answer.⁵

In New York, if the house were in Utica, the questions are yours to set out.

None of the three sets asks whether Joanne should have stayed in bed, gone out the back, or had a lamp to hand. They ask what she faced, what she believed, and whether what she did matched it. The home changes which line applies in England and Wales and removes the retreat duty in New York; it does not change the questions in Scotland.

Protecting property

This is general information, not legal advice. The law differs by state, and between England and Wales, Scotland and Northern Ireland.

Everything so far has been about a person in danger. Take that away, leave only a threat to things, and the jurisdictions part company.

In England and Wales, defence of property is one of the defences section 76 governs, but it is not self-defence, so it is never a householder case.¹² The ordinary rule applies: force that is disproportionate is not reasonable (s.76(6)). The leaflet says it plainly: "disproportionate force to protect property is still unlawful". It also says: "However, you are still allowed to use reasonable force to recover your property and make a citizen's arrest."³ Section 3 of the Criminal Law Act 1967, from lesson 13, is the arrest and crime-prevention half of that.

In Scotland, as the answer above says, self-defence reaches only personal danger.⁵ This course read nothing else on Scots law about using force to protect property, so it can't tell you whether any other rule covers it.

Under the Model Penal Code, force to protect property is allowed when the person believes it immediately necessary to stop an unlawful entry, a trespass or the carrying away of movable property, or to take the property back, either straight after it was taken or, in cases the Code sets out, later (§3.06(1)). The Code usually wants a request to desist first, unless asking would be useless or dangerous, or the property would be damaged before the request could be made (§3.06(3)(a)).⁶ Deadly force is allowed only where the person believes the facts fit one of the cases §3.06(3)(d) lists. One is against someone trying to take the person's dwelling from them without any claim of right to it, meaning any genuine belief that they're entitled to it. The other is against someone committing "arson, burglary, robbery or other felonious theft or property destruction" who has either used or threatened deadly force, or where any lesser force would expose the person or someone with them to "substantial danger of serious bodily injury".⁶ Read those again and most of them are about danger to a person, not the value of the thing.

In Texas, the statute goes further, and it may be the rule you've heard of. Section 9.41 allows force to protect land or property, and force to recover it immediately or in fresh pursuit (chasing straight after it was taken) where the person reasonably believes the taker had no claim of right, or the taker used force, threat or fraud. Section 9.42 allows deadly force "to protect land or tangible, movable property" if all of three things hold.⁹

1. The person would be justified in using force under §9.41.
2. They reasonably believe deadly force is immediately necessary "to prevent the other's imminent commission of arson, burglary, robbery, aggravated robbery, theft during the nighttime, or criminal mischief during the nighttime" (criminal mischief is Texas's name for damaging property), or to stop someone fleeing straight after a burglary, robbery, aggravated robbery or theft during the nighttime from escaping with the property.
3. They reasonably believe either that the property "cannot be protected or recovered by any other means", or that using less than deadly force to protect or recover it would expose them or someone else to a substantial risk of death or serious bodily injury.

This is general information, not legal advice. The law differs by state, and between England and Wales, Scotland and Northern Ireland.

Two more statutes read for this course tie deadly force to named crimes rather than to property as such. Florida allows force short of deadly force to stop a trespass or interference with property, and deadly force only when someone reasonably believes it necessary to prevent the imminent commission of a forcible felony, the list lesson 13 named, with burglary and robbery on it (§776.031).⁸ New York's §35.20 allows deadly force against arson, and against a burglary of a dwelling or occupied building.⁷ So Texas is not the only statute read here that allows deadly force in connection with property crimes.

On traps, the texts line up. The leaflet names setting one to hurt an intruder as something that could be prosecuted, and the Model Penal Code and Texas allow a device to protect property only if it is not designed to cause, or known to risk, death or serious bodily injury (Code §3.06(5); Texas §9.44).³⁶⁹

Tariq and the shop

This is general information, not legal advice. The law differs by state, and between England and Wales, Scotland and Northern Ireland. The sets below list a court's questions; none of them is an answer.

Tariq lives in the flat above his hardware shop in Barnsley, with a door from the flat straight down into the shop. At 1am he hears the shop's back door go, and goes down the inside stairs. A man is filling a bag with power tools. He turns, lifts a crowbar and comes at Tariq, and Tariq shoves him hard into the shelving. The man drops the crowbar, grabs the bag and runs out of the back door into the yard. Tariq follows him into the yard and grabs the bag, and the two of them wrestle for it until the man lets go and climbs the fence.

In England and Wales, in the shop: he lives above it with an inside way through, so the shop is treated as part of his dwelling (s.76(8B)).¹ A man coming at him with a crowbar makes it self-defence. So it can be a householder case, and the questions are Ray's two: was the shove grossly disproportionate, and if not, was it reasonable as he believed things were?¹²

In the yard, the rule stops twice over: the yard is wholly outside the building, and Tariq is now after the bag, protecting property, not himself.¹² So the ordinary line applies. Was wrestling for the bag disproportionate, or was it the reasonable force to recover property that the leaflet allows?³ Lesson 13 gave the leaflet's line on chasing someone who runs.

In Scotland, the shop part is asked the ordinary way (imminent danger, cruel excess, a reasonable escape), and there's no householder rule to call on. The yard part meets the manual's "personal danger, not material loss". If the man had turned on Tariq in the yard, the self-defence questions would start again.⁵

In Texas, unless the wrestling counted as deadly force (Texas defines it in §9.01(3), which lesson 13 described), §9.42 does not come into it, though a man fleeing at night with property is the kind of case its second limb names. The question is §9.41's: did Tariq reasonably believe the force he used was immediately necessary to recover the property, in fresh pursuit after it was taken, and did he reasonably believe the man had no claim of right to it, or had the man taken it by force, threat or fraud?⁹

What people get wrong

Each of these is general information, not legal advice. The law differs by state, and between England and Wales, Scotland and Northern Ireland.

"At home, any force that isn't grossly disproportionate is fine." Not in England and Wales. As the CPS summarises Ray, disproportionate force short of grossly disproportionate "was not ... of itself" reasonable; the jury still asks whether it was reasonable.² The leaflet says the same in plain words: "The force you use must always be reasonable in the circumstances as you believe them to be."³

"The householder rule covers my garden, my drive and my things." It covers force used in or partly in the building, in self-defence. Not the garden, and not property.¹²

"You'll be prosecuted for fighting off a burglar." The England and Wales leaflet says police have a duty to investigate a death or injury, and also that "very few householders have ever been prosecuted".³ Both hold at once.

"Grabbing something to defend yourself makes it worse." Not on the leaflet's account above, and the CPS summary of Ray lists picking up an object that would lawfully be to hand as one of the circumstances a jury can weigh.²³

"Castle doctrine means anything goes at home." It removes or limits the retreat question, in Florida and Texas adds a presumption, and in Florida force the chapter justifies also brings immunity from arrest and prosecution (§776.032(1), lesson 13). None of the texts drops the requirement that force was believed necessary, and Florida's presumption has exceptions.⁶⁷⁸⁹

"You can shoot someone for stealing." Not in England and Wales. Scotland's self-defence covers personal danger, not property, and this course read no other Scots rule. Under the Model Penal Code, only where the theft comes with deadly force or a danger of serious injury. Texas's §9.42 is the exception you may have heard of, and all three of its conditions have to hold; Florida and New York also allow deadly force against some named crimes, burglary among them, as the property section showed.³⁵⁶⁷⁸⁹

Practice

Connections

Back. Lesson 13, "The law on using force", gave the four questions this lesson has taken indoors, and its account of deadly force and the Model Penal Code holds here unchanged. Lesson 5, "Home, the door and the doorstep", gave the first step, the call, and this lesson keeps its label.

Forward. Lesson 15, "Carrying something for protection", turns from force used at home to the separate question of what you may carry outside it. Lesson 16, "Afterwards", covers the investigation the leaflet says will follow a death or injury, and your rights if you're questioned. Trespass, burglary and ownership are each far bigger than the corner of them a safety course needs; they, and the rest of the criminal law, are for Introduction to Law in a later term of the Core.
