Where a will conflicts with proprietary estoppel

This High Court case involved complex family litigation, challenging the last will and testament of a deceased woman and raising claims of a lack of testamentary capacity, undue influence, and proprietary estoppel regarding the inheritance of a family farm.

Facts:

The deceased had two daughters, Ruth (mother of the claimants, John and Steven) and Sheila. The core dispute arose over the inheritance of the farm, which represented a significant asset. The claimants brought a suit challenging the validity of the 2016 and 2017 codicils on the grounds of lack of testamentary capacity, want of knowledge and approval, and undue influence. Alternatively, they claimed that the farm should pass to them via proprietary estoppel, based on the clear and unequivocal assurances that they would inherit the farm from a young age and their reliance on such promise.

The deceased drafted a will in 2006, which provided that the estate would be split equally between her daughters. A codicil of 2011 varied the will to leave the farm directly to the deceased’s grandsons (Ruth’s children). However, a 2016 codicil subsequently revoked the 2011 codicil and reinstated clause 4 of the 2006 will, returning the principle of equal division of the whole estate, including the farm, between the two daughters. This codicil was executed following a meeting with the solicitor, Mr. Smale. The deceased decided on this change because she "could not reconcile the unfairness to Sheila's family" of leaving the main asset only to Ruth's side. She hoped the daughters would "sort out a way" for the grandsons to run the farm. In 2017, the deceased made further disposition, leaving Hook Meadow to Sheila, but confirmed the equal division of the residue.

In parallel, the deceased and the claimants entered a partnership, predominantly for inheritance tax (IHT) purposes and secure agricultural property relief (APR). The claimants' father, Peter, surrendered his tenancy of the farm to facilitate this. The partnership agreement included an option for the claimants to buy the farm upon the deceased's death or retirement.

Sheila alleged that the deceased's signatures were forged on four documents (M&G withdrawal forms and partnership accounts) to extract funds for the benefit of the Maile family (Ruth and the claimants) after the 2016 codicil was made, an allegation which was confirmed by expert evidence. 

Decision: 

The High Court dismissed the claimants’ claim, while Sheila’s counterclaim succeeded. The Court upheld the validity of the deceased's final testamentary wishes and ordered the claimants and their parents to vacate the farm and pay damages for unlawful occupation.

The Court first analysed the deceased’s testamentary capacity and ruled that she had met all three limbs of the test – the deceased had understood that the 2016 codicil revoked the gift of the farm to her grandsons, thereby restoring the principle of equal division; she was aware of her main assets, including the farm, cottages, and investments; and her final decision was a conscious effort to achieve fairness between her daughters. The claimants, however, failed to prove the high threshold of coercion. 

The claim for the farm based on estoppel failed because the claimants could not satisfy the core requirements. The alleged statements (e.g., "one day this will all be yours") were found to be vague and generalised encouragement, and not a clear and unequivocal promise that the deceased would make an irrevocable testamentary gift. The claimants' actions, such as working on the farm and entering the partnership, were found to be primarily motivated by familial duty, kindness, and the family's shared interest in the IHT savings resulting from the partnership, rather than reliance on the promise of inheritance. This was reinforced by their admission that they continued to work on the farm even after knowing the 2016 codicil had revoked the promise.

Implications:

This case reinforced the principles of testamentary freedom, the difficulty of establishing proprietary estoppel against a testator's will, and the importance of clear documentation in family farming disputes.

Vague statements of encouragement ("one day this will all be yours") do not override a properly executed will. A testator is generally free to change their mind unless a promise is made with an "irrevocable" quality that is clearly relied upon, a standard which the Court found was not met in this instance.

The Court scrutinised the process of changing the will, confirming that the deceased's motivation to achieve "fairness" between her daughters was formed on a sound and rational basis, dismissing claims that this decision otherwise stemmed from coercion or a lack of capacity.
