As part of the British Horse Society's work to record paths before Path Extinguishment Day, it was spotted that Sheafgreen Lane was recorded as a bridleway, yet the historical evidence strongly suggested that it should be recorded as a restricted byway. An application was made to record the higher status.

Legal History 1840: Aston 18 was shown on the Aston tithe map as not subject to an apportionment. 11 Mar 2013: Application to record as restricted byway. HCC reference STV/33 and EH/401. 3 Sep 2023: Lack of public bridleway sign at western end reported to Hertfordshire County Council, reference 401003646944.
