Four members of my family had a 4 acre plot of land bequeathed to them. A lawyer wrote up the boundaries of each 1 acre plot, however separate deeds have not been granted because each lot has not been perk tested. But I believe this may constitute as a "color of title". The plot of land is 1 acre wide and 4 acres deep. The only way to access the other three acres is to cut a road through the first one. If one has "color of title" or a deed for the first lot is it possible to refuse access to the other three owners’s access to their land, and at the same time claim "Adverse Possession" on the other three lots? If so, is there a way to stop this before the 10 year statute of limitations?
