Easement
By prescription

Once they become legally binding, easements by prescription hold the same legal weight as written or implied easements. But, before they become binding, they hold no legal weight and are broken if the true property owner takes appropriate acts to defend their ownership rights. Easement by prescription is typically found in legal systems based on common law, although other legal systems may also allow easement by prescription.
