There is an article in today's Times-Tribune reporting that Chesapeake  "has filed a civil complaint in Wayne County Court against the county recorder of deeds office claiming it has encumbered land leasing there."

Which brings up something that makes me uneasey ... the policy of some OG companies to record only a Memorandum rather than the full lease.  Particularly if a lease has Addenda, it's too important a document not to be part of the public record.   (With the possible exception of financial terms, if agreed to by both parties.)
