If her will creates a trust for oldest child, then no. But in general, yes. If the house was in mother's name and she has passed away, the personal representative can sell the house (unless the will specifically directs another disposition for the house). If the house was deeded to the siblings, then any owner can sue for partition. (Note that this answer is for Oregon). Honestly, selling the house is the better idea. Joint ownership of real property by five people is a recipe for ongoing fighting which will tear your family apart.
