It should. of course, but in the probate case which I am pursuing (on behalf of the Thai widow), 9 months after his passing. his Gov pension was still being paid. His private pensions had been cancelled though !
I have since informed HMRC, but it makes me wonder if the pension would have been paid until they didn't receive the bi-annual "certificate of Life".
Also. wonder how they would go about clawing back the overpayment if the account wasn't subject to probate ?
