DF died 5 years ago. DM died 1 year ago. 
Benefit people say they were paid several thousand pounds in excess of what they were entitled to/ Looks like they hadn't mentioned all their savings to the benefits visitor that filled in the claims for them.
DB and DS want to challenge it, but I can't see what there is to challenge if parents had more savings than they should have had.
AIBU to think we just have to pay this from the estate if parents weren't entitled to it?
