PODs (Paid on Death) and TOD (transfer on death) will alleviate probate. Also, in some states a home can have TOD (transfer on death) also. It is treated the same as if the person received an insurance policy. In our case we only have one child so we did this. The only other thing is to have a will that indicates that he is able to pay the bills after we are gone.
IL... My son is very frugal (more than I am sometimes). I don't think he is "greedy" only that he thinks we should pay for everything since we are "loaded". I think this mentality would expand if he knew our net worth. Not that it is much ... but to him it would seem like a fortune. He thinks we should be candid about money with him but because of this attitude we are very leery of saying anything. I have told him there may not be any inheritance since we have many years left (hopefully) and if we get sick that may be it. A conundrum.
