Guest v Guest & Anor

A proprietary estoppel claim requires an assurance or representation, reasonable reliance and detriment caused by that reliance. The elements are interconnected and must be assessed in the round. In an expectation case, silence alone cannot ordinarily create an estoppel without a prior assurance. An assurance may be sufficiently clear despite being indirect, provided its meaning is objectively established in context. Uncertainty about the precise extent of the promised interest is not necessarily fatal where the property is identified. Relief ordinarily begins with the claimant’s expectation, but must remain proportionate to the detriment and take account of the interests of the owner and others. The court may award a clean-break lump sum rather than transfer property where that is necessary to satisfy the equity and avoid an unconscionable result.

Andrew Guest claimed a proprietary estoppel equity against his parents, David and Josephine Guest, in Tump Farm and the associated dairy farming business. He alleged that assurances made over many years led him to devote his working life to the farm for modest financial reward. The parents denied giving any assurance and counterclaimed for possession of Granary Cottage and an occupation rent.

The court considered whether there had been a sufficiently clear assurance, reasonable reliance, detriment and unconscionability, and, if an equity arose, how it should be satisfied. The central issue was whether Andrew had established an equitable entitlement despite the parents’ testamentary freedom and the subsequent breakdown of the family succession arrangements.

1. Proprietary estoppel established. The court found that David, with Josephine’s tacit support, had consistently led Andrew to believe that he would inherit a substantial share of Tump Farm and would be able to continue farming there. The assurances were sufficiently clear when assessed objectively and in the context of the family relationship and dealings. They did not promise sole ownership or exclude provision for Ross and Jan.
2. The fact that Andrew’s expectation changed over time, particularly when Ross became involved in farming, did not defeat the claim. Nor did the absence of a precise division of the property make the assurance insufficiently certain. Tump Farm was identified and the expected interest was substantial.
3. Andrew reasonably relied on the assurances. He worked on the farm from the age of 16 for more than 30 years, undertook substantial managerial and farming responsibilities, supported associated businesses and accepted modest remuneration. The provision of accommodation and other benefits did not remove the detriment. Detriment had to be assessed in the round rather than by mathematical calculation.
4. The parents’ withdrawal from the succession expectation was unconscionable. The disputes concerning the Ladysmith Farming Partnership, Andrew’s conduct after 2012 and his later alternative employment did not materially reduce the equity. A proprietary estoppel claim concerned an equitable interest arising during the owners’ lifetimes and was not confined to a remedy under the Inheritance (Provision for Family and Dependants) Act 1975.
5. In exercising the remedial discretion, the court began with Andrew’s expectation but applied proportionality and considered the parents’ continuing interest, the interests of the other children, tax consequences and the need for a clean break. A transfer of property or continued occupation was impracticable because the family relationship had irretrievably broken down.
6. The appropriate remedy was a lump sum comprising 50% after tax of the value of the dairy farming business and 40% after tax of the value of the freehold land and buildings, subject to the stated valuation and life-interest adjustments. No order was made on the counterclaim for occupation rent.
