Losing a parent is the ultimate step in growing up and I send my sympathies on your loss. Hope it goes well, solicitors and bank people can be very helpful. I was my father's executor- he died 8 years after Mum, and my sister who had been in this country when he died, decided to b****r back to Canada where she lives leaving me to organise funeral and do everything. That's another story,but I did my best as I felt I owed it to him and was proud of my achievement after it was all done.
(I hope they would have been proud of me - last "duty" as a daughter)
