When a person sells the land but not the mineral rights

A person that I know sold their land in Iraan Texas. They did not give up their mineral rights but have recently learned that someone forged their signature. How does the rightful owner of the mineral rights let the leasing companies know that this has happened.

What forms need to be filed with Pecos county in order to fix the forged Notary and what other actions can help the owner of the minerals. I spoke with someone in the Attorney Generals office who stated that the former owner of the land may have a criminal case on forged documents. If anyone can help please message me.

A forged deed is invalid and placing a fraudulent deed of record is a felony.

Seems to me like you should call a good lawyer and the DA.

The original owner will have to file suit alleging forgery and trespass to try title to get the minerals back, unless the current owner in possession is willing to concede a forgery occurred and give the property back.

A person you know sold their surface estate but reserved their minerals. What document exactly is it that that person alleges was forged? A Mineral Deed, Warranty Deed, Oil and Gas Lease, what?

I echo Pete's curiosity.
