Stallion v Albert Stallion Holdings (Great Britain) Ltd & Anor

Proprietary estoppel requires a sufficiently clear assurance, reasonable reliance, and substantial detriment caused by that reliance. Foregoing the certainty of an order for ancillary relief may itself constitute substantial detriment; evidence of the hypothetical relief that might have been obtained is not essential.

Where an equity arises, relief is not measured mechanically by either the claimant’s expectation or detriment. The court must determine the minimum remedy necessary to do justice, while maintaining proportionality and considering benefits already received and the position of others. A written promise to provide rent-free accommodation for life may be satisfied by continued occupation without exclusive possession until the contractual circumstances for termination arise.

Porntip Stallion claimed a proprietary estoppel against the freehold owner of 75 The Cut, seeking a life interest and exclusive occupation. She alleged that she had consented to divorce proceedings and foregone ancillary relief in reliance on promises made by Albert Stallion and his adviser.

The defendants disputed the alleged promise of exclusive occupation, reliance, detriment, unconscionability and the appropriate relief. The central issues were the terms of the representation, whether the elements of proprietary estoppel were established, and how any resulting equity should be satisfied.

1. Representation. The court found that the only representation made, and in any event the only one relied upon, was contained in the written agreement of 29 June 1994. It did not promise exclusive possession. The alleged later agreement providing exclusive occupation was unsupported by the evidence and inconsistent with the parties’ subsequent conduct. Any such representation would also have been insufficiently clear as to the premises covered and the date on which exclusive occupation would begin.
2. Proprietary estoppel. Applying the principles identified in Thorner v Major, [2009] 1 WLR 776, Wayling v Jones, 13 P&CR 170, and Gillett v Holt, [2001] Ch 210, the court held that the written assurance was sufficiently clear, that it had induced Porntip to consent to the divorce and not seek ancillary relief, and that the resulting detriment was substantial. Foregoing the certainty of a court order was itself sufficient detriment; proof of the likely amount of ancillary relief was unnecessary.
3. Unconscionability. Considering the matter in the round, and applying Yeoman’s Row Management Ltd v Cobbe, [2008] UKHL 55, the court held that it would be unconscionable not to honour the written assurance.
4. Relief. The court applied the guidance in Gillett v Holt, Jennings v Rice, [2003] 1 P&CR 100, and Sledmore v Dalby, 72 P&CR 196. The minimum equity necessary to do justice was continued rent-free residence for life, without exclusive possession, until the circumstances in clause 3 of the agreement arose. The court took account of the fifteen years’ occupation, the needs of Lilibeth and her family, and the benefit already received.
5. Clause 3 and possession. Clause 3 was construed as requiring both sale of the property and vacation of the premises before the £55,000 payment became due. A desire to redevelop did not satisfy that condition. Accordingly, the right to remain continued, and the claims for possession and mesne profits did not arise. Further argument was reserved on the precise terms of the order.
