None that I am aware of, I wasn't even aware I was financially connected at the time of living with him, other than a shared adress for less than a year.
I've been registered on the electoral roll where I am now since 2008, and I have been in continuous work here. I also stated in the letter that I was happy to provide evidence of this should they need it.
I think I'm shocked more than anything, he has siblings which would be those in charge of his estate and finances.
It's more a case of I literally have no idea what he's been doing since I left. They even ask for the national insurance number of anyone dealing with his estate, I don't even know their names!
