This is good, but distributing the mining fees evenly across all lawyers will result in too low a fee for the work involved. What if, instead, the parties of the contract would each pick a small set of lawyers ("representing" lawyers) to receive their fees for enforcing the contract. Rather than relying solely on the mining lawyers for this contract to participate in consensus (as that number is now small and adversarially motivated), we would expand the consensus pool to all lawyers who participated in sufficiently similar contract enforcement in the past, using their votes on previous enforcements as an immutable record.
In this design, determining the threshold for similarity may require the participation of a third-party "oracle" or "judge" component.
