When I was in need of a lawyer I phoned a few. Most firms asked me to send all relevant documentation which I did do. I never ended up engaging a lawyer. However one firm has just sent me an invoice for $400. When I queried it, they said it was for perusing documents. There was never any discussion about payment. If I knew I was being charged $400 for them to look at my documents, there is no way I would have emailed them. Aren't they supposed to discuss payment?
