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?
What he inherits is his to dispense as he chooses.
However, in some states there is a legal way to fight the will if the spouse does not get a fair division of the martial assets. This may be the path you will take when the will is in probate. (Meaning after he dies). If your Mom is in a nursing home at that point...you can be sure the NH and/or Medicaid will be filing to challenge the probate of that will.
