I don’t have any expertise and my situation is much different from yours, but I recently spent around $800 for an oil/gas attorney to draft
- an heirship affidavit to prove the seller owned the minerals and
- a mineral deed for him to sell them to me.
This was in Arkansas and for a $3,000 mineral rights purchase.
I’m only sharing because I was expecting much higher attorney fees and was pleasantly surprised by my invoice. Definitely find out how much an attorney will charge before you agree to work with them, if you go that route. Assuming there’s reason to believe that the minerals will be productive, I personally prefer to pay to have the task done so I can have at least some control over the timeline.
If anyone on here contradicts me, probably listen to them and not me. I’m no authority and have hardly any experience. Best wishes!
