Forcible entry describes entering land or buildings without lawful authority using force, threats, intimidation or other conduct overriding the occupier’s will. It commonly arises in criminal law, landlord and tenant disputes, repossessions and protest or trespass litigation.Historically, “forcible entry” was a standalone criminal offence in England and Wales and in Ireland, but most old common law and statutory offences have been repealed or replaced by modern offences (for example, criminal damage, burglary, aggravated trespass or violent disorder). Northern Ireland has similar modern offences rather than relying on historic forcible entry laws. In Scotland, the concept appears mainly through common law breach of the peace, malicious mischief and statutory protections for residential occupiers; there is no single codified “forcible entry” offence.Across the UK and Ireland, the term is now largely descriptive rather than a technical label, but it remains relevant when assessing whether entry was lawful, whether reasonable force was used (for example by enforcement officers, police or mortgagees), and whether civil remedies such as injunctions, interdicts, possession orders or damages for trespass and harassment are available.
