Need your advice on a peculiar situation:
Subdivision A is enclosed by Subdivision B, with no path to a public road/highway other than going through B.
After several years of residents from Subdivision A being freely able to transverse Subdivision B, the latter just recently starts demanding stickers and refusing entry to those residents in the enclosed property.
Does subdivision B have a right to enforce this and refuse A residents the "only" path to get to their property? For subdivision B, have they acquiesced the right of A residents right of way after letting them through for several years?
Please advise. Thank you.
