Habberfield v Habberfield

In proprietary estoppel, the remedy must be proportionate to the claimant’s detriment, but proportionality is evaluated through a flexible judgment rather than mathematical comparison. Where assurances and requested performance resemble a bargain, and the claimant has substantially performed, the court may treat the promised expectation as a proportionate measure of relief, subject to countervailing circumstances.

Refusal of an offer falling short of the assurance does not necessarily extinguish the equity. Waiver requires knowledge of the right and communication of its abandonment. The court assesses unconscionability retrospectively when the assurance falls due, taking account of the whole course of dealings and subsequent changes of circumstances. An appellate court will interfere with the trial judge’s wide remedial discretion only on established grounds governing review of discretion.

For about 30 years the respondent worked long hours for low pay on her parents’ farm. She did so in reliance on assurances that she would eventually control and own a viable dairy farm, subject to provision for her siblings and her parents’ continued occupation. In 2008 she rejected a proposed partnership because it withheld control and made inadequate provision for her partner. She nevertheless remained at the farm until 2013.

Birss J held that proprietary estoppel was established and awarded £1.17 million, representing the value of the Woodrow farmland and buildings without the farmhouse. His decision was reported at [2018] EWHC 317 (Ch), [2019] 1 FLR 121. The appellant challenged the continuing equity, post-2008 detriment, proportionality and immediate payment. The respondent cross-appealed concerning her partner’s work and deductions from the award.

1. Both the appeal and cross-appeal were dismissed. The trial judge had a wide judgmental discretion when deciding how to satisfy the proprietary estoppel. An appellate court could intervene only for legal misdirection, reliance on an irrelevant consideration, omission of a relevant consideration, or a decision outside the area of legitimate disagreement.

2. The 2008 offer did not extinguish the equity. It neither gave the respondent the promised control of the dairy business nor stated that rejection would forfeit her expected inheritance. Waiver would have required knowledge of the relevant rights and communication that they were being abandoned. The parents had not materially changed their position in reliance on any supposed abandonment. Unconscionability had to be assessed retrospectively, when the assurance was repudiated, and by reference to the whole course of dealings rather than one event.

3. The judge could find that reliance and detriment continued after 2008. The offer was not an unambiguous final offer. The principal detriment was not merely financial: the respondent had positioned her working life around the assurances. That loss of opportunity and life choice could not reliably be reduced to pounds and pence. Any possible detriment arising from her partner’s underpayment was speculative and, even on assumptions favourable to her, could not have affected the order.

4. The relevant proportionality comparison was between the detriment and the remedy. It was not a mathematically precise exercise. Proprietary estoppel claims form a spectrum. Where the claimant substantially performs requested acts in return for a sufficiently clear assurance, party autonomy supports treating the promised benefit as a generally proportionate reward. The expectation remains a factor rather than an automatic entitlement and may be reduced for countervailing circumstances. Save in the most exceptional circumstances, relief should not exceed the expectation.

5. The judge could reduce the expectation to reflect the cessation of dairy farming and the cost of reinstating a dairy unit. That was a non-culpable change of circumstances rather than a penalty imposed on the respondent.

6. Immediate payment was within the judge’s discretion despite its harsh effect. The evidence entitled him to find that a sale would leave the appellant able to obtain another home and maintain her income. The suggested tax consequences were insufficiently evidenced. The order therefore did not exceed the respondent’s equity or fall outside the permissible range of remedial judgment.

1. Court of Appeal (Civil Division): By [2019] EWCA Civ 890, unanimously dismissed both the appeal and the cross-appeal.
2. High Court, Chancery Division: Birss J held that the respondent had established a proprietary estoppel and awarded £1.17 million to satisfy the equity: [2018] EWHC 317 (Ch), [2019] 1 FLR 121.
