I thought I sold my oil interest

And now 25 years later I’ m a letters wanting to lease my property. Why?

Ask whomever is trying to lease how they got your name and if they have checked its title. A lot of times, they do a wide sweep first in leasing without really checking title.

Here are the Carter County Records with your name: https://okcountyrecords.com/results/name=benford%2C+john:site=carter/page-1 There is something listed as a Conversion Deed in 1996 but no images available.
I would not warranty title in any lease other than agree to return any consideration (bonus) money.

Than you very much. I thought that maybe the sale I made only covered the sale of that particular well and that I might still retain rights to further exploration.

Thank you. Maybe I still own other rights which may not have been conveyed by that conversion.

I see my name in the site too. I don’t know anything about the conversion mortgage though. I need a manager for my mineral properties. I have to find help to clean this up.
