My father died in 1990. My mother listed mineral rights in Pecos when she filed probate in Michigan where they lived. In 2012 my mother and siblings and I received offers for mineral rights in Reeves county. We were previously unaware of these mineral rights. The company offering to buy stated my mother owned 1/2 of the interest and the other 1/2 was split between the 5 children. Mom and one sibling sold at that time. In 2019 we started receiving offers again. One landman making stated Mom did not have the right to sell previously because the whole interest should have gone to the children since it was not listed on probate. He wanted her to sign a statement that she had a life interest only. I guess my guestion is how do I find out how the interest should have passed. Texas law or Michigan law?
I do not know Texas or Michigan law, but I’m fairly certain that the interest passes according to the state where the land or mineral interest is in. Unless there is a will dictating otherwise.
