One of the most important legal requirements when making a will is that the person making the will (the testator) has testamentary capacity. This means they must fully understand what they are doing and the consequences of their decisions. Without testamentary capacity, a will may be challenged and possibly declared invalid after the testator’s death. Let’s break down what this means, how it’s assessed, and why lawyers ask so many questions during the will-making process.
What Is Testamentary Capacity?
Testamentary capacity refers to the mental ability of the testator to make a valid will. The courts have used the Banks v Goodfellow (1870) test for over a century to determine whether a person had the mental capacity to make a valid will. According to this test, a person must be able to:
- Understand the nature of making a will – They need to know they are creating a legal document that dictates how their property will be distributed after their death.
- Understand the extent of their assets – The testator should have a general understanding of what they own, such as property, money, or personal items.
- Comprehend who should benefit from the will – This includes understanding their relationships with family members, friends, or other potential beneficiaries and who might reasonably expect to inherit from them.
- Be free from mental disorders – The person must not be suffering from delusions or mental health issues that affect their ability to make rational decisions regarding their will.
If any of these elements are missing, the person may lack testamentary capacity, which can lead to potential legal challenges.will genuinely reflects the deceased person’s last wishes.
The Complexities of Assessing Capacity
For lawyers, determining whether someone has testamentary capacity can be tricky. Lawyers are not doctors, so they rely on observations, the client’s behaviour, and sometimes medical opinions to make an assessment. This is particularly challenging when dealing with elderly clients or those with health conditions that may impact their mental state, such as dementia or Alzheimer’s disease.
One complexity arises because capacity can fluctuate. A person may have moments of clarity followed by periods of confusion, especially if they are suffering from a degenerative condition. In such cases, it can be hard to know whether they had the required capacity at the exact time they made the will.
Additionally, clients can appear to understand what they are doing, even when they don’t. For example, a testator might say “yes” to a series of questions about their assets and family, but a deeper conversation may reveal they don’t fully grasp the implications of their decisions. Lawyers must be diligent in ensuring the client’s understanding goes beyond surface-level responses.
Why Lawyers Ask Lots of Questions
When preparing a will, a lawyer may ask what seem like irrelevant or repetitive questions. This is not to make the process more difficult but rather to ensure that the person making the will has testamentary capacity.
By asking questions about a testator’s family, finances, and specific wishes, lawyers are testing whether the person fully understands the important aspects of their will. A seemingly irrelevant question about a distant relative or minor asset may reveal whether the testator has genuinely thought through their decisions. Lawyers also try to identify any potential undue influence, which could invalidate the will if someone is pressuring the testator.
In cases of uncertainty, the lawyer might even suggest getting a medical assessment to confirm the testator’s capacity. This is often done to protect the will from future challenges and ensure that the testator’s final wishes are carried out as intended. Testamentary capacity is a crucial aspect of making a valid will. It ensures that the testator understands what they are doing, who they leave their assets to, and the consequences of their choices. For lawyers, assessing capacity is not always straightforward, so they ask so many detailed questions. Their goal is to protect the testator’s wishes and prevent future legal disputes that could harm the intended beneficiaries.ormal, it’s essential to ensure your mental capacity is not in question, and your wishes are clearly expressed. For peace of mind, seeking legal advice to ensure your will is valid and enforceable is always a good idea.

Frequently Asked Questions (FAQs)
1. What does testamentary capacity mean when making a Will?
Testamentary capacity refers to a person’s mental ability to make a valid will. This means the testator must understand what a will is, know the general extent of their assets, and recognise the people who may reasonably expect to benefit. This standard is based on the long-standing Banks v Goodfellow test.
2. Why is testamentary capacity important for a valid Will?
A Will can be challenged or declared invalid if the testator did not have testamentary capacity at the time it was made. Ensuring capacity protects the document from future disputes and helps ensure the testator’s wishes are followed.
3. Can someone with dementia or memory loss still have testamentary capacity?
Yes, it is possible. Capacity is task-specific and can fluctuate. A person with dementia may still have lucid moments where they fully understand the will-making process. The key requirement is that they had capacity at the time the will was signed.
