Inherited mineral rights / lease offer "newbie

New to all of this. Our family has mineral rights in Hughes County, OK. Three people share in the rights as it has been inherited and split amongst heirs. One of the parties has received a letter offering a lease or sell option for the mineral rights (my aunt). Don’t all three parties have to agree on how to proceed? I talked to the landman who sent out my aunt’s letter, and he did not have correct information from the courthouse. I am going to try and fix that. Is that the best way to start things rolling correctly? How do I know what is/is not a “good” lease offer?

Diane: Each mineral owner can make their own decision regarding leasing, selling, etc. Each of you own an undivided 1/3 interest in whatever the group inherited (assuming you each inherited a 1/3 interest). Recording an Affidavit of Ownership in the county land records with your current contact information is a good way to make sure anyone interested in your acreage can locate you.
