Commentary on provisions of the Act Temporary possession and use of land Section 18: Enforcement of restrictions on land use
Section 18 enables covenants between the Secretary of State and persons with an interest in land entered into by agreement to bind successors in title to such interests even though they are not direct parties to the original covenant.
	In order for covenants concerning land to be enforceable against successors in title to such land, the person claiming the benefit must usually have a neighbouring interest in land. The Secretary of State will usually not have such an interest until compulsory purchase powers are exercised. Therefore, to enable covenants which bind successors in title to be entered into before that time, this section removes the requirement to have a neighbouring interest in land.
