Part I del Landlord and Tenant Act 1987 prevede la possibilitá per i proprietari di appartamenti residenziali in edifici con parti residenziali e parti commerciali (mixed use) di avere un diritto di prelazione nel caso in cui il freeholder decida di vendere il freehold (se i requisiti previsti dall'Act sono presenti). Nel caso in cui il freeholder non notifichi la vendita e non dia la possibilitá di esercitare questo diritto, ci sono severe ripercussioni come il caso Artist Court Collective Ltd v Khan dimostra
In Artist Court Collective Ltd v Khan , concerning a mixed user building, the freehold interest (Mr Khan) was transferred to another of his companies for the sum of £225,000. Mr Khan failed to notify the tenants of the transfer, a breach of the Act. Having become aware of their rights, the tenants served a purchase notice on the company requiring the property be transferred to them for the same price. To avoid that, Mr Khan transferred the property back to himself, again, without informing the tenants, but this time, for £0.00 (nil consideration). On discovering the further disposal, the tenants served another purchase notice. The court held that the transfers qualified as “relevant disposals” under the Act. Mr Khan was required to transfer the property to the tenants for nil consideration.
