We have a will and a trust. It is set up so that should something happen to us, our kids don't get the bulk of our life insurance initially. They get half at age 25 and the other half at age 35. College and educational costs can still be paid. We did that because DH and I both spent very irresponsibly in our 20's as I expect many people do. This way if they do the same, they only get half then, and the other half in the thirties when most likely they are much wiser with money.
