Thanks Rod, The more case history I read the less sure I am of how a judge would rule. It almost seems like a subjective choice by the judge depending on the way they want to look at Part Performance.Not sure of your use of the word 'combine' in "...thought to combine Part Performance with Promissory Estoppel"
Your statement of claim should keep the concepts separate, so you will duplicate some actions that occured or at least cross-reference the actions.
And yes, it is possible Promissory Estoppel may be applicable.
