Mom and stepdad have been married 40 years. Mom has Alzheimer's. Stepdad has 2 children from previous marriage. Stepdad and his 2 daughters are rewriting will. It shall state that if mom dies first, stepdad gets all the $. If stepdad dies first, their assets will be divided into quarters: to mom, me, and my step sisters. I don't agree. I think mom should get it all if he dies because she worked for it just like he did. She will need medical assistance in a few years, long term placement, etc. What can I do to make sure mom is taken care of properly in her final years?
