I agree with Todd but would also suggest, if the minerals reside in a state other than your residence, work with your local attorney and the outstate attorney to ensure both actions work in unison.
I`m happy to see your in the thought process of who should inherit. Many times the mineral holdings and their records a neglected as you have viewed on other posts on this site. Todays legal costs are far less than 5, 10 or 20 years down the road. You are aware of the ownership detail where others would have to piece together your estate assets after you pass.
