Your tenancy and lease are legally binding documents which contain clauses relating to antisocial behaviour and nuisance. Once you sign this document you are responsible for the behaviour of those who live in your home and those who visit you. Breach of your tenancy or lease is a serious matter and can result in court action being taken against you for example eviction, demotion of tenancy, antisocial behaviour injunction, antisocial behaviour order or fortiture of lease.
