I now realise my stupidity.
The client was unable to claim a foreign pension fund and had a battle for outstanding arrears on a UK one. I located and realised both the pensions and negotiated with HMRC to allocate the pension arrears to the corrct year thereby maximising the tax repayment.
The client who suffers from dementia and other ailments attempted to have my modest invoices allowed as disability expenditure but was turned down on the basis that his 2 carers could have done the work as part of their duties
Very humbling for an old accountant who can now understand his true worth
