Ever wonder if easements stay with the land or if they are just granted to a particular person? It really depends on how it is set up.
When a new easement is created it must be signed not only by the owner of the property it will cross but also by any mortgage holder. If the current lender doesn’t consent to the easement and the property is later foreclosed, the easement would be considered to be terminated.
A license agreement gives only a personal privilege or permission to use the land of another. It does not run with property. A license is revocable by the property owner and often can be revoked on short notice.
