I am the executrix of my mom & dad's estate. My name is on their checking account and as the beneficiary of their savings, etc.
I also have been assigned the difficult task of pulling the plug or not allowing the plug should it come to that.
I don't think I would want to be in charge of more than this and my own family. I know it's important to have a will and living will set up. We have guardianship set for our four boys and we update it every couple of years. Since we have four boys - should we both die at the same time - we wanted to make sure the guardians would and could take all four boys.
To answer your question? Unless everything was spelled out, I might say no to more.
