// THE SHORT ANSWER

A solicitor's undertaking is a binding promise a lawyer gives in their professional capacity to do something: most often, at a property settlement, to pay the outgoing lender from the purchase money and deliver its discharge so that the new lender's mortgage can be registered first. Breaking one is a professional disciplinary matter as well as a legal one, which is why lenders and lawyers rely on them to move money and documents at the same moment. An email promising a discharge later is not one.
