Undertaking as a binding promise: commitments expressed or conveyed in proceedings create enforceable obligations. The document defines undertake/undertaking as a promise, engagement, stipulation or covenant by which a person assumes an obligation or responsibility, possibly operating as a guarantee or security and not necessarily requiring consideration; it also explains that promises or undertakings given in legal proceedings bind the party if their conduct conveys that an undertaking is being given, regardless of the party's subjective understanding.
