what's the cheapest way to declare bankruptcy in the UK?

i have a customer who has vast debts – to a border which a intentional agreement with creditors seems questionable to have clearness – i’ve googled a complaint though am usually entrance up with ‘free advice’ from companies who wish to sell their services – intentional agreements, negotiations etc.

what i need to undergo is either we can acknowledgement yourself broke as well as what’s a cheapst approach of you do it? i’m a solicitor as well as do not have a monetary imagination to answer this as well as it sounds lame, in my ears, to converse – go see a CAB…any associating resource out there?

thanks in advance
