Family Home Trusts and Proprietary Estoppel
Trusts > Family Home Trusts and Proprietary Estoppel
Candidates frequently lose marks because they confuse the test for a common intention constructive trust (Rosset and Jones v Kernott) with the test for proprietary estoppel (Thorner v Major), and they fail to identify the requirements for establishing a constructive trust interest in family home scenarios.
What Is Family Home Trusts and Proprietary Estoppel in SQE1?
Two main doctrines govern interests in family homes where legal title is in one person's name but another has contributed to the purchase or to the home's improvement. Common intention constructive trusts arise where both parties intended the legal owner to hold on trust for a beneficial interest, evidenced by express agreement or common understanding (inferred from conduct). Proprietary estoppel arises where one party has encouraged another to believe they have an interest in the property, and the other party has relied and acted to their detriment.
These doctrines overlap but are distinct, and the requirements differ. Understanding when each applies is essential to advising on family home disputes.
This topic connects closely to types of trusts and is a key part of the Trusts syllabus for SQE1.
Key Principles for SQE1
-
Common Intention Constructive Trust: The Test (Lloyds Bank v Rosset): A constructive trust arises if: (1) there was a common intention that the legal owner held on trust for a beneficial interest (express agreement is sufficient, or the intention can be inferred from conduct), and (2) the claimant has acted to their detriment on the basis of that intention. The detrimental reliance must be substantial.
-
Express Agreement: The clearest case is express agreement that the legal owner holds on trust. If A and B agree "I will buy the house in my name, but we hold it on trust for us both," a constructive trust arises. Express agreement can be inferred from written or oral statements.
-
Inferring Common Intention from Conduct (Rosset Test): Where there is no express agreement, common intention can be inferred from conduct. In Lloyds Bank v Rosset, the House of Lords held that conduct alone (contributions to the purchase price, or payment of the mortgage, or payment of household expenses) is insufficient to infer common intention. However, conduct can corroborate express agreement. The question is whether the parties' conduct, objectively assessed, shows a common intention to hold beneficially.
-
Financial Contribution and Detrimental Reliance: The claimant must prove that they acted to their detriment on the basis of the common intention. The most direct form of detrimental reliance is a direct financial contribution to the purchase price (e.g., paying part of the deposit or the mortgage). Contributions to improvement of the property, or contributions to household expenses, may be detrimental reliance but are weaker evidence than direct payment for the purchase.
-
Quantifying the Beneficial Interest (Jones v Kernott and Stack v Dowden): Once a constructive trust is established, the courts must determine the quantum of the beneficial interest. The approaches differ. In Stack v Dowden (a House of Lords decision on joint legal owners), the court held that the beneficial interest follows legal title unless the beneficiary proves otherwise. In Jones v Kernott (where one party is the sole legal owner), the court looks to the parties' intention regarding shares, and in the absence of clear intention, the court may infer the fairest solution based on the whole course of dealing.
-
Modern Application: Inferring Intention: Modern cases have moved away from Rosset's strict requirement of express agreement or direct financial contribution. In Jones v Kernott, the Supreme Court suggested that common intention can be inferred from the whole course of dealing, including non-financial contributions (care of children, homemaking) and indirect contributions. However, Rosset remains the leading authority on the initial test for establishing the trust.
-
Proprietary Estoppel: The Test: Proprietary estoppel arises where: (1) the claimant was encouraged by the legal owner to believe they had an interest in the property (by words or conduct), (2) the claimant relied on that belief, (3) the claimant acted to their detriment on the basis of that belief, and (4) the legal owner knew or ought to have known of the claimant's reliance and did not correct the belief. This is particularly relevant in family contexts where an elderly person (often a parent) encourages an adult child or grandchild to work on the property or to care for them, with the expectation (but without clear promise) of inheriting.
-
Detrimental Reliance in Proprietary Estoppel (Thorner v Major): The detriment must be substantial and must be something the claimant would not have done absent the belief in the interest. In Thorner v Major, a claimant who worked on the property for years without payment, relying on an understanding (however vague) that the property would be inherited, satisfied the requirement.
-
Remedy in Proprietary Estoppel: The court has discretion to award a remedy that is proportionate to the detriment suffered. The remedy may be a beneficial interest (full or partial), a right to occupy, or monetary compensation. The court will not award more than is necessary to prevent unconscionable conduct.
Exam tip
A common mistake is treating common intention constructive trusts and proprietary estoppel as the same. They are distinct. A constructive trust requires common intention (express or inferred from conduct) and detriment; proprietary estoppel requires encouragement, reliance, and detriment. Additionally, Rosset requires clear evidence of common intention if not expressly stated; mere financial contribution is insufficient. In family home disputes, always ask: is there evidence of agreement to hold on trust (constructive trust) or evidence of encouragement to rely on an interest (estoppel)?
How This Appears in SQE1 Questions
A scenario might be: "A and B are partners. A owned a house in A's name. B paid for the kitchen renovation and contributed to the mortgage payments. B claims a beneficial interest in the house. Does B have a constructive trust interest?" The answer requires understanding Rosset's test: contributions to mortgage payments and renovations alone are insufficient without evidence of common intention. B must show either an express agreement or conduct from which common intention can be inferred. Merely making financial contributions does not establish common intention.
Alternatively: "G (a grandparent) told their grandchild C, 'Help me with this farm and it will be yours.' C spent 30 years improving and working the farm, never questioning whether they would inherit. G has now died and the will leaves the farm elsewhere. Can C claim an interest?" This is a proprietary estoppel case: G encouraged C to believe in an interest, C relied and suffered detriment, and the remedy is to award C an interest (or compensation).
This is a classic SQE1 trap.
Common Mistakes Students Make
- Confusing common intention constructive trusts with proprietary estoppel; they have different requirements and different legal bases
- Assuming that financial contributions alone establish a constructive trust interest; Rosset requires common intention
- Overlooking that proprietary estoppel protects reliance even where there is no clear agreement or promise; the test is whether the legal owner encouraged belief in an interest
- Misapplying Stack v Dowden or Jones v Kernott; these cases determine quantification of beneficial interest, not whether the trust arises
- Treating proprietary estoppel as always resulting in a full beneficial interest; the remedy is discretionary and may be partial or take the form of a right to occupy or monetary compensation
Quick Summary
- A common intention constructive trust arises where the parties intend the legal owner to hold on trust and the claimant has acted to their detriment on that basis.
- Common intention can be express (a statement of agreement) or inferred from conduct, but Rosset requires clear evidence of intention; financial contribution alone is insufficient.
- Proprietary estoppel arises where the legal owner encouraged the claimant to believe in an interest and the claimant relied and suffered detriment.
- Jones v Kernott and Stack v Dowden address quantification of beneficial interest, considering the parties' intention and the whole course of dealing.
- The remedy in proprietary estoppel is discretionary; the court will award relief proportionate to the detriment suffered.
- In family home disputes, always consider both constructive trust and estoppel theories; they may overlap but have different requirements.

Quick check questions based on this article.
Question 1
Scenario
A couple purchase a house together for £350,000. Legal title is registered in the name of one partner only. Both partners contributed to the purchase price: the legal owner paid £250,000 and the other partner paid £100,000. There is no express declaration of trust and no written agreement as to beneficial ownership. The couple live together in the property for six years. During this time, the non-legal owner pays for a £40,000 extension to the property, increasing its value to £450,000. The non-legal owner also pays one-third of the monthly mortgage repayments. The couple separate and the non-legal owner claims a beneficial interest in the property. The legal owner argues that the non-legal owner is not entitled to any beneficial interest because their name does not appear on the title. The non-legal owner has kept detailed records of all payments made. The property is currently valued at £500,000. The legal owner has been offered a new position abroad and wishes to sell the property quickly. The non-legal owner seeks advice on the extent of their beneficial interest.
Which of the following best describes the likely basis on which the non-legal owner would establish a beneficial interest?
Question 2
Scenario
A farmer tells his nephew that if the nephew works on the farm without pay, the farmer will leave the farm to the nephew in his will. Relying on this assurance, the nephew gives up a well-paid position as an accountant and works full-time on the farm for 15 years without any salary. During this time, the nephew makes significant improvements to the farm buildings using his own savings, spending approximately £80,000. The farmer's solicitor advises the farmer on several occasions to formalise the arrangement, but the farmer always says he will 'deal with it later'. The farmer dies intestate, and under the intestacy rules the farm passes to the farmer's estranged daughter. The nephew brings a claim based on proprietary estoppel. The farm is valued at £1.2 million at the date of death. The farmer's daughter argues that the nephew's claim fails because there is no written agreement and the nephew was merely a volunteer. The solicitor who advised the farmer confirms the conversations took place but cannot recall the precise wording used. The farmer never made a will despite the solicitor's repeated recommendations.
Which of the following best describes the nephew's claim based on proprietary estoppel?
Question 3
Scenario
A man owns a house in his sole name. He told his partner, a woman, at the time of purchase that 'this house belongs to both of us equally.' The woman, relying on this statement, paid for substantial renovations costing £25,000 and gave up full-time employment to manage the household and care for the couple's child. The couple have now separated. The man argues that any trust of land must be evidenced in writing under section 53(1)(b) of the Law of Property Act 1925 and that the woman cannot establish a beneficial interest without a written document. The woman's solicitor has reviewed the file and confirmed that there is no written declaration of trust, no written agreement between the parties, and no correspondence referring to shared ownership. The only evidence of the man's statement is the woman's own testimony, which is corroborated by a text message from a mutual friend who was present at the time.
Which of the following best describes whether the absence of writing prevents the woman's claim?
