My 92-year-old mother has a trust that divides her assets three ways (me, my brother, and my sister) when she dies. My brother was recently diagnosed with dementia and will have to spend the rest of his life in a nursing home. Will my brother's third of the assets have to be turned over to the nursing home? If so, should my mom change her will? If not, and my mom passes away, should I put his share in a trust until he is either recovered or passes away? Thank you.
