Louisiana law heir property
My grandmother lived on 70 acres lad that she got half of when my grandfather died- and his children got the other half. When she died she gave her interest to my brother and when my mother died- she gave her interest to her children (four of us). The three of us (brother and two sisters or daughters) signed it all over to my oldest brother so that he could buy the other heirs out and get it all in one name. Then it was agreed that he would then divide the property among the four of us siblings. He never did that would never give it back. Now he and his wife are getting divorced and she is getting half of the place. Is this legal for her to be entitled to any of the land that was in my family- not hers? Please help me.
