Apparently my paternal German grandfather took out some sort of savings policy when I was born, he died ten years later. My sister believes that my Grandmother continued to pay into this account and it came to light when she died about five years ago. My father dealt with the will, but I have been estranged from him for years. My sister also fell out with my father, but much more recently and sometimes still sees him she has tried to ask about it, but gets the brush off.
I don't know if this account did exist or not, unfortunately my father has past form on financial cheating and it's very likely that he took the money for himself.
I've known about it for a while and have mostly given up the idea of ever seeing it, but money is tight at the moment and I wondered if anyone has any idea of how I go about finding out if the account did exist. I don't speak German, but my sister does so she could help.
