Big Mess with Antero and Heirship

Hi everyone. So my husband is stressed about the situation he is in, which is as follows (Be prepared its a long story):

So over 30 years ago my husband (then about 18 years old), was approached by a gentleman in a suit in California. The gentleman had asked my husband if he had a will, in which he responded no. The gentleman had then asked “Well son you have inherited a large amount of money and something called mineral rights in West Virginia, but you need a will to receive any of the money”. The conversation goes on and at the end the gentleman in the suit laughed when my husband asked “Are you talking like $1,000 or a couple of thousand” his response was “Ha young man, we are talking a life changing amount with more 0’s then you can wrap your head around”. At the time my then 18 year old husband wasn’t in the right state of mind, under the influence and his mother had just passed away. He never looked into the whole mineral rights thing, with that being said Antero Resources here in Colorado had mailed him a letter at the beginning of 2019 and had said and I quote “… We believe your family has a oil and gas interest in Tyler County, West Virginia. We are trying to locate all the heirs of Margaret Claudette Reed (his deceased mother) to start the payment process for this interest.”

A couple of months pass and this is what we know (either we found out, Antero Resources told us or our Lawyer found out):

  • Affidavit of heirship mentioning the amount 362.74 acres more or less
  • There is a large amount of wells (forgot the exact amount, ut they had mentioned all were producing for over 100 years)
  • He received a check for payment on the production of 3 wells for 3 years
  • Apparently EQT had been the I guess oil company originally pumping or what not on the acres, and then they sold their acreage to Antero Resources

These Mineral Rights have been in his family since atleast 1901 from Tyler County, West Virginia. My main thing is what do we do now? The lawyer we hired isn’t wanting anyone and I mean anyone involved with his findings and my husbands case. Meaning my husband feels like he’s not telling us everything he knows.
