As someone who for a living, investigates false claims and declarations (not for the DWP or whichever agency/LA deals with any claim submitted by Accy by the way), I know the lengths I will legally go to and the sources of information I will check, if necessary seeking Court Orders, to see if what I am being told is correct.
As a taxpayer, I would expect any claim to be properly reviewed. Given that the Government is hell bent on reducing public spending even further, the experiences of others who have posted in this thread and the experiences of my own family and friends, I'd suggest the adoption of realism not optimism.
