Roads Act 1993

A council may direct the owner of a private road (other than a classified road) to carry out such work as, in the opinion of the council, is necessary to prevent the road from becoming unsafe or unsightly or, if of the opinion that it is appropriate that the work should be carried out by the council at its own expense, may carry out any such work itself.

If there is more than one owner of a private road, the respective owners are liable to pay those expenses in such proportions as the council decides.

In deciding the proportion of expenses to be paid by the respective owners, the council must have regard to—

the benefit that any particular land will derive from the work, and

the amount and value of any work carried out in respect of the road by the respective owners or occupiers of the land.
