If you do a binding nomination the super fund has to follow it. In most cases you also have life insurance with your super which means the final payout is usually much more than just the balance of your account. In my case DH and I have left 100% to each other and set our insurance at a level which would allow either of us to pay of the mortgage etc so that the surviving one could continue to provide DS with the life that he is accustomed to and not need to worry about making ends meet.
Thanks, yes thats what i was thinking.
I just wasnt sure who to leave it to.
