Firm whose head office is situated in an EEA state other than the UK and which is incorporated in that state.

Trespass

A tort committed with ‘force and violence’ on the person, property or rights of another. All three types are actionable per se without proof of damage unlike nuisance where the interference is indirect and requires such proof. Wrongful interference with goods is covered in the Tort (Interference with Goods) Act 1977. Liability policies do not cover intentional acts but most public liability policies cover liability from accidental trespass, false arrest, false imprisonment and invasion of privacy. Some cover also exists in respect of loss of documents under professional indemnity policies.
***
Trespass consists of the entry of a person or a thing upon land in the possession of another without permission.
