Bit complicated - pair of semi's share a drive. The land registry shows boundary of full drive is to one of the houses. However the plans show the drive as shared access. Is the other house responsible for helping to maintain the shared drive - should it say so in the deeds? Something like 'right to pass the driveway on the plan subject to the transferor paying a fair proportion according to the use of the cost of repairing renewing and maintaining the said driveway' - does that mean pay to maintain drive???
