Section 23(10) of the Crofters (Scotland) Act 1993 establishes that a croft is vacant if it is not occupied by: a croft tenant, an owner-occupier crofter; a subtenant approved by the Commission under Section 27 or a tenant on a short lease approved by the Commission under Section 29A. Therefore anyone who holds title to croft land which is not occupied by one of the above categories must be the landlord of a vacant croft. The Commission can regulate the occupancy of vacant crofts through giving notice to the landlord under Section 23(5) to submit proposals for letting the croft.
