I inherited some land from my grandmother. After examining her paperwork on this property, I noticed a right-of-way easement was given to an oil company for a high pressure gas pipeline. Her signed documentation contains no terms or conditions. Yet, a copy of the company's documentation shows a term for 50 years with a handwritten modification for an option for another 50 years. I believe this contract for this easement is illegal and was never void. There are no initials verifying my grandmother was aware of this change. I am trying to find a law which states the legalities of an unsanctioned modification and that this contract is breached. Thank you.
