Again, depends on state law. Also the majority of "estates" never go through probate at all, if things are set up with that in mind. Assets simply pass by operation of law and no probate is required. I've set up my assets in that way. My mother and father did also. No probate was required in their estates and none will be required after I die. Unless you have a large and/or complicated estate an attorney can help you do this inexpensively and simply, without your having to give up control of your assets before your death.
Probate is an expensive and unnecessary hassle for most people.
