Lloyds Bank plc v Rosset [1991] 1 AC 107

A husband acquired a house in his sole name using family funds and mortgage borrowing. His wife was closely involved in preparing and renovating the property as their home, supervising builders and undertaking work. She made no direct contribution to the purchase price or mortgage repayments relied on in the claim. When the bank sought possession, she asserted a beneficial interest protected by occupation. The Court of Appeal had accepted her position, but the lender appealed. The House of Lords considered whether the evidence established any beneficial interest before it became necessary to resolve overriding protection.

Had the wife established a beneficial interest through common intention and detrimental reliance, such that her occupation could protect an interest against the mortgage lender?

The House of Lords allowed the bank’s appeal. No agreement, arrangement or understanding to share the property beneficially had been established, and the wife’s renovation activity did not justify inferring one on the facts. Lord Bridge distinguished an established sharing agreement followed by detrimental reliance from a claim relying wholly on conduct to infer the agreement. In discussing the latter, he gave particular importance to direct contributions to purchase or mortgage payments. Because the wife had not established the underlying beneficial interest, she could not defeat the lender through occupation. The decision should be read with later domestic-property authorities which examine wider dealings, not as an unchanged exhaustive code for every family-home claim.

Occupation cannot protect a beneficial interest which has not been established. Rosset distinguishes express sharing arrangements supported by detrimental reliance from inference through conduct, but its restrictive discussion of contributions requires consideration alongside later authorities such as Stack v Dowden.

Rosset is especially useful for ordering the analysis: establish the proprietary interest before asking whether occupation protects it. Its House of Lords outcome reversed the earlier Court of Appeal decision, which remains a separate historical record in this library. Stack later discusses the development of common-intention trusts and the different starting points for sole and joint names. Students should not present renovation work as either automatically sufficient or universally irrelevant.
