After a call from a landman related to 12.5 NMA I started one on my deceased grandfather for my dad and his brother’s children. I then emailed it to my attorney who is familiar with the family history and he inserted his name and address as the affiant. He signed and had it notarized and then I picked it up and filed it with the Grady County Clerk’s Office. My attorney did not charge me anything, so the only cost was the $17.00 filing fee with the clerk’s office. (Still waiting on my dad and cousins to reimburse me the $17.00.) 
My dad and cousins are now receiving royalties on 2 horizontal wells.
