My son recently passed away. His girlfriend listed herself as his de facto on the death certificate (shared a flat for 6 months). I cannot access his paperwork to confirm who he had listed as a beneficiary. On his other superannuation account, he listed his brother as 100% beneficiary. How is it decided who the super is passed onto? The fund won't tell me any details. I am worried if he had a death benefit she may be paid this amount. They lived together (when he wasn't in the hospital) but weren't financially dependent. We (his parents) where the ones who helped him financially when needed.
