Unmissable
The situation you describe would be treated as a"Death in Deferment", because your EDP is not a pension. Your real pension has been preserved at your date of retirement, and payment defered to age 65. Hence my understanding (although you must get this confirmed) is that your widow would be paid your age 65 pension lump sum and her widow's pension (based on your preserved pension) from your date of death. She would obviously need to know how to go about claiming the pension and what proof of your date of death and previous service would be required, so make sure you find out and leave clear instructions where she or your executor can find them.
