My father died last year and was in receipt of a work pension for many years. I informed them of his death and have now received a letter telling me they were, around the time if his death, 'reviewing' his pension, with the result that they have decided he was overpaid by over £7000. This is apparently because his Guaranteed Minimum Pension was not appropriately split out from other benefits resulting in a higher pension than he should have received. They are blaming previous pension administrators for the error.
I have no idea what this means. There is money in the estate to pay, but do I just take their word for it? If not what proof can I ask for? I'm pissed off it has taken this long to come to light and that the investigation apparently only started on his death. If he had known about it he definitely would have told me.
