The letter I received from Br Gas was:
"15 June 15 - - Dear Pyotr Petrovich
The Estate of Jarn Smith
gas numero - - -
elec numero - - -
Thank you for your recent letter about the above accounts.
I understand that the late Mr Smith left no estate to clear the above balance. Having received the requested documentation, I confirm the account has been updated and the charges withdrawn.
we have arranged for the death certificate of the late Mr Smith to be returned to you and you will receive that in a few days
thank you for contacting British Gas
X Y Z customer service."
I cant remember the relevant documentation - the Death cert of course - although I prepared a final account - with documentation for every debt, I never sent it to anyone. Incredz because it took me hours to prepare, and I expected sallow chain smoking clerks to stab it at personal interview and complain that 3p was lacking here and 4/6 was too much there.
I did NOT seek letters of representation for intestacy
on the grounds that it cost £315 and no prospect of anyone getting any moolah. ( I buried him at my cost)
