My situation is slightly different, because my father is still alive, and has three heirs. He set a trust up, based on both his lawyer’s and CPA’s advice, documenting his wishes, which with regards to oil and gas interests, was to receive the royalty money and deposit it to the trust, then immediately disperse the royalty payments to the three siblings, each of which would pay their own taxes. He also included language that would avoid any future controversy. He knows that money can sometimes change everything…what was once a good relationship between siblings could turn sour at any minute, due to greed, irresponsibility, incompetence, etc., so he wanted to ensure fairness, while at the same time, having everything legal made nice and tidy. If I was in your situation, I would not enter into a partnership, corporation or LLC with my siblings,but your relationships may be much different than mine. I would encourage you to consider legal, binding agreements to split things evenly, and be done with it. Then no one has to bother with the others actions or attitudes. And in the end, I can only urge you to consult with your attorneys and CPAs to get guidance on your individual situations, and hopefully you all can reach a mutual and fair agreement. Best wishes.
