Where the owner of a property agrees with an introducer to pay a fee conditional upon the property being sold for a certain amount to the person he introduces, and the property is sold for less than that amount, does the property-owner have an obligation, contractual, statutory or restitutionary, to pay reasonable remuneration to the introducer for their services? The Supreme Court had to grapple with this problem in its recent judgment in Barton v Morris [2023] UKSC 3. Robert Sterling of Chambers was, we are pleased to report, on the right side of the argument.
