Recent posts have considered some of the key issues in relation to assessing testamentary capacity.
Another case that provides an informative perspective on the key issues is Carr v Homersham [2018] NSWCA 65. As usual if you would like a copy of the case please contact me.
The decision confirms that there is a presumption of mental competence that arises in relation to any will that is rational on its face and is duly executed.
The presumption is only displaced by circumstances which raise a doubt as to the existence of the deceased's testamentary capacity at the time the will was signed.
Relevantly, the existence of an 'insane delusion' under which the deceased laboured does not of itself preclude a finding of testamentary capacity if the delusion had no effect upon the will. Helpfully, the case confirms the key factors that are relevant in this regard as follows:
- It is insufficient to demonstrate the absence of testamentary capacity to prove that the deceased acted on a material mistaken belief in making their will.
- Instead, for a mistaken belief to rise to the level of a 'delusion' which affects the validity of the will, there must at least be a high degree of irrationality in the belief.
- Ordinarily, evidence will be required that there has been an attempt to reason the deceased out of the belief, such that the deceased's adherence to it suggests that the deceased has a mental disorder or deficiency precluding the deceased from comprehending and appreciating 'the claims to which they ought to give effect'.
- Generally, the circumstances must be such that it can be inferred that the deceased was wedded to a mistaken belief, irrespective of its truth. If that is not the case, the belief is likely to be no more than a mistaken view, the holding of which cannot be inferred to reflect on the deceased's mental competence.
- A mere mistaken belief is not sufficient to invalidate a will. Instead, there must be an element of irrationality such that an inference can be drawn that the deceased has adhered to the belief regardless of evidence demonstrating its falsity.
- If the mistaken belief is one that the Court can infer the deceased could have been reasoned out of by the presentation of evidence of its falsity, its origin in a mental deficiency will not be able to be inferred.
- The fact that the deceased suffered from dementia, was not inconsistent with her retaining testamentary capacity at the relevant time. While it was clear that the deceased's memory difficulties were at least in part reflective of that disorder, there was no evidence indicating that the existence dementia impacted on the deceased's mistaken belief that was in issue in the case.
