Leasehold Casualties (Scotland) Act 2001.

In a relevant lease (i.e. in a lease of land granted before 1 September 1974 for a period of not less than one hundred and seventy-five years), any provision which stipulates for payment of a casualty is void; and, accordingly, any such payment which would, but for this subsection, have fallen due on or after the relevant day shall not be exigible. "Casualty" means any duplicand or other periodical or casual payment stipulated in a relevant lease to be payable by the tenant to the landlord in addition to the rent. Where a casualty is extinguished by virtue of section 1 of this Act, a landlord may, not later than one year after the day on which this Act received Royal Assent, give written notice to the tenant: (a) requiring the tenant to pay to him compensation calculated in accordance with section 3 of this Act; and (b) specifying the amount of compensation required as calculated by him; and the tenant shall be liable to pay such compensation.
