Can I attack a burglar in self-defence?
Conditional — necessary defence rules out punishment, but only while the attack lasts and the defence is necessary. Under Article 21 of the Criminal Code, an act committed in necessary defence is not unlawful, and that is the defence which is indispensable to repel from oneself or another a simultaneous or directly imminent unlawful attack. Three words matter: simultaneous (the attack is ongoing or imminent), indispensable (no milder option) and unlawful. Here the most dangerous myth falls — „my house, my rules”: Croatian law knows no American castle doctrine. A burglar who is fleeing or whom you have already overpowered may not be injured out of revenge, and property alone does not justify grave injury or death. If you exceed the limits of defence, you may be punished more leniently; you are not guilty only if you crossed the limits due to excusable strong fright caused by the attack.
📋 The rules
- Statutory definition: under Art. 21 of the Criminal Code, necessary defence is that which is indispensable to repel a simultaneous or directly imminent unlawful attack on oneself or another.
- The attack must be ongoing: defence is allowed while the attack lasts or is imminent; there is no necessary defence against an attack that has ended or a fleeing attacker.
- The defence must be necessary: you choose the mildest means that repels the attack; clearly disproportionate force (say lethal force against a minor attack) falls outside necessary defence.
- Property is not life: protecting things does not by itself justify grave injury or killing the attacker; the proportion and the real danger to people are always weighed.
- Exceeding the limits: whoever exceeds the limits of necessary defence may be punished more leniently, and is not guilty if the limits were crossed due to excusable strong fright caused by the attack.
🔓 Exceptions
- Defending another: necessary defence also protects a third person — you may repel a simultaneous unlawful attack aimed at someone else on the same terms as defending yourself.
- Traps and automatic devices: pre-set traps (say an electrified fence) can meet the simultaneity requirement only if they trigger exactly at the moment of the attack; otherwise it is unlawful injury.
- Necessity: when danger to oneself or another is averted and it is not a matter of repelling a human attack, the rules on necessity apply, which have their own, narrower limits.
⚠️ Penalties & fines
If your conduct was within the limits of necessary defence, the act is not unlawful and is not punished. The risk starts with exceeding it: for an intensive excess (excessive force) or an extensive excess (defence after the attack ended) you answer for the act committed — bodily injury, a serious offence or killing — with the possibility of a lighter sentence. Guilt is excluded only if the excess results from excusable strong fright. The hidden costs are huge: even if you are finally acquitted, a criminal case runs until then, detention is possible, and the weapon or means you defended yourself with is seized. Alongside criminal liability, civil liability for damage to the injured attacker looms if it is found you crossed the limits. That is why it pays to call the police and defend yourself only as much as is necessary, no more.

❓ Frequently asked
May I injure a burglar who has entered the house?
You may defend yourself while the attack on you or your household lasts or is imminent, and only as much as is necessary to repel it. Once the attack has ended or the burglar is fleeing, there is no more right to necessary defence and further violence becomes punishable.
Does the „my home, my castle” rule apply in Croatia?
No, Croatian law knows no American castle doctrine that would justify violence just because someone entered your home. A simultaneous unlawful attack and the necessity of defence are always required, and mere breach of possession or property is not enough for grave injury.
What is exceeding the limits of necessary defence?
It is a defence stronger than was necessary or one that continues after the attack has ended. You then answer for the act committed, but may be punished more leniently, and are not guilty if you crossed the limits due to excusable strong fright caused by the attack.
May I set a trap or electric current against a burglar?
Very risky: pre-set traps meet the simultaneity requirement only if they trigger exactly at the moment of the attack. If they injure someone outside an attack or disproportionately, you answer for bodily injury or a graver offence, because that is no longer necessary defence.
May I defend another person, not just myself?
Yes, necessary defence also covers defending a third person from a simultaneous unlawful attack on the same terms as defending yourself. Here too the defence must be necessary and proportionate, and it ends the moment the attack stops or the attacker gives up.
