What is the name of your state (only U.S. law)? Nebraska, I bought a piece of property, on disclosure there was no mention of an abandoned pipeline or easement rights. Called diggers hotline, they came out and marked the property, (this pipeline was not marked) proceeded to put in the basement, 90% through the project my contractor hit the abandoned pipe that ran under the house. Called the proper authorities, gas company came out, said they were unaware of any pipeline, they spent the next 2 days researching and found a blanket easement dated 1932. Said they have easement rights and to move the basement. (a portion of this property, since 1932 was subdivided around 1968) I found a modification of easement document dated 2005, signed by the new owner of the undivided portion of this land, this new document that states ALL easements are released and Except the Right of Way that runs behind my property. The gas company said this modification does not include my property just what my neighbor owns. If modifications are made to the 1932 blanket easement document, does it affect the whole blanket easement or just the easements with whom the gas company signed the modification document?
