It's a great point about volume. However a huge number of legal cases + contracts never get started in the first place because of cost. So those would be absent from your success rate.

To put it bluntly there is no point in writing a contract for a $200 dollar job. Countless little guys get screwed over every day because of this. Ultimately they work by handshake deals or through family businesses because working with larger corps is a headache. My father for example had to pay 200 euros for a large firm he worked for to process some paperwork they also invented. That is; a firm that he works for, he has to pay them money, in order to be hired by them in the future. This is probably illegal but this is what happens when you can't risk finding out whether this is a breach of contract. That seems like a failure to me.

That's where I see digital contracts making a real difference. Making the legal system comprehensible and inexpensive for the working poor.
