What happened to the Atrisco Land Grant after US annexation?

After the United States took control of New Mexico, the Atrisco grant’s boundaries and ownership were challenged in U.S. courts. The heirs faced costly legal battles and difficulty proving their claims, and parts of the land were sold off. So the grant was not expanded or preserved intact; the best answer is “It was sold off in parts due to court costs and lack of proof.”
