I hope everyone understands this is catnip for lawyers. Probate court is the biggest scam going. THE LAWYERS GET THE MONEY. It doesnt take 5 years to settle this. Both sides were working it. They took that estate for everything they could get.
You have a proper will drawn up by a good T&E lawyer, you don't even need a lawyer to probate. I've probated three wills, it's not difficult at all.
