Part I provides the reader with an account of the development of the doctrine of adequate assurances from its earliest roots in the doctrine of anticipatory repudiation. Part II explains the workings of the modern doctrine in the context of a recent case. In Part III, I argue that promises made in response to a demand for adequate assurances can be understood as a class of enforceable promises. In Parts IV and V, I attempt to work out the back-end consequences that would result from treating assurances as enforceable promises.
