Flora-mae - your father doesn't need to have died more than 25 years ago. I obtained my dad's WW2 records in 2007 after my mother died and only 4 years after my father's death. However, I had to send my father's death cert, his marriage cert and my mother's death cert to show that I was his living next of kin. Bit silly really, because if my mum had still been alive, I think she could have got his records for nothing.
