Both parents had a very simple and clear will. It dont matter. Everything still goes to probate, takes minimum 6 months, and lawyers take their cut.
Listed beneficiaries on any money accounts is an absolute must. Should be immediate dispursment and they trump any will. Plus, lawyers are bypassed. You just better make sure the beneficiaries are up to date
I've been told a "trust" is basically the same process as a will... except the lawyers are involved/paid before you die, instead of afterwards. But I have not verified that.
