So, do you believe Honey had a will that would leave a significant portion of her estate to someone other than Barry and her children? Why would she do that?
Barry's will was very explicit about what would happen if Honey survived him, and then later died. Multiple trustees were appointed to oversee this process.
It seems, while Barry was alive, he directly supplied her with income, ie oversaw how much she got and basically what for.
Is it likely that Honey would be encouraged to then, privately, separately, create a will that contradicted the intent of Barry's will? That if she died first, she might leave everything she owned to her sister, or a cat rescue or other charity, rather than have it remain with Barry as part of the ultimate family legacy to their children?
I think Barry saw it as quite straightforward - under probate, if she had died before Barry, everything would become his. No will necessary.
If she had survived 30 days beyond Barry's death, his will would have been invoked, the trust would have been created, etc.
IMO, the only things she might have meant by a will, would be momentos like a particular painting to so-and-so who admired it, or something. But that stuff's minor and tedious while you are living a full life.
I think they both operated on the same principle - if you want to give stuff away, give it while you're alive. Once you've died, it all becomes part of the family legacy.
