Thanks, my gran was in a nursing home and the fees took up a lot of the inheritance so there wasn't much left in the pot to inherit apparently. I'm beneficiary of 25% and my auntie has 75% now that everyone else has given up theirs (she would have had 50% anyway).If your auntie had been the only full time carer, then maybe you could consider it.
You only have your father’s word that everyone else has given up their share.
I would take the money, put it in a savings account and wait and see if the others really have made over their share and if she really needs it.
Then decide. There is no rush to do anything.
My other gripe is that they didn't even contact me to tell me she had died and id have been happy with some photos or brooches which were never offered.
