Section 31(1), Highways Act 1980 states:
"Where a way over any land, other than a way of such a character that use of it by the public could not give rise at common law to any presumption of dedication, has been actually enjoyed by the public as of right and without interruption for a full period of 20 years, the way is to be deemed to have been dedicated as a highway unless there is sufficient evidence that there was no intention during that period to dedicate it"
