I keep thinking the answer is yes, though I'm not sure what we would change.
DH and I have a joint will that is about 20 years old, made when our children were young. If we updated it, the provisions would be basically the same - leave money to each other, or if we both go at once then split it between the kids. We're better off now than 20 years ago, but would/should there be anything we now need to reconsider in a will?
