Is there a general time-limit for complying with conditions set out in a decrofting direction. In other words does the direction cease to have effect if the conditions have not been complied with within a particular period?

If it is an advance of purchase direction issued to the tenant of a croft, the direction will not take effect unless the tenant or their nominee purchase the area within 5 years of the date of the direction: Section 25(4) of the Crofters (Scotland) Act 1993. If it is a direction issued to an owner of a croft the Commission may impose conditions (including timescales) relating to the proposed use of the land (Section 24(3)).
