This chapter shows how partnership was able to function as organisational law, in effectively allowing the assets dedicated to the concern to be used primarily for its purposes, but also highlight the fragility of this ‘ringfencing’ effect. The assets settled for the purpose of the business are treated as separate from the assets of the shareholders, and so ‘bonded’ to the business, its disponees, and its creditors, rather than the shareholders. The focus of this chapter is on the extent to which Regency era legal rules allowed asset partitioning of this type, and so allowed what we would today regard as commercially efficient forms of trading. In the Regency era, commercial parties could not usually incorporate, and a sole trader would simply be liable in the same way for any debts he contracted. The chapter also asks whether traders regarded the law of partnership as sufficient to meet their needs, in light of the limitations of its asset partitioning rules.
