In California, it was all but impossible for me to probate my mother's will simply because it wasn't written in the proper form; if you have a copy of the will that shows your husband as executor and there is no probate on file then there will likely be problems in going through probate other than just making a redistribution; the worst thing, though is that you will have to live with these aunts from now on and you will need to decide what sort of relationship you want.
