It is with many thanks I say to you Mr. Cotton, thanks again for being on this forum and taking your time to answer and share your knowledge with us.
My understand from your links and answer is:
1: B and C cannot sign a OG lease without me and my spouse signing and questionable on the needing for the remaindermen signature. With executive rights on B and C we have no share and share alike, and the fuduciary duty is not there as we do not get 1/3 of A's bonus or royalty money, only the interest. From your links - this is where the Lessee I guess, could give us an ORI on just A's part and not B and C part. Do not know if a division order can do that?
2: If the remaindermen does not sign, then when he dies, not me and my spouse (life estate) die, the lease we signed as the executive on B and C becomes (for a better word) voided?
I guess I need to stop and step back and stop looking for all the variables as a life estate owner, but wait for a CPL to come with a OG lease.
