Psychiatry Witnesses

Case type

Wills & Probate

Probate disputes frequently turn on whether the testator had testamentary capacity at the time the will was made, applying the test in Banks v Goodfellow (1870) (and increasingly the Mental Capacity Act 2005). Retrospective psychiatric assessment of the deceased, based on medical records and witness accounts, is often required.

  • Short case summary and the questions you want answered

  • GP and psychiatric records (full set where available)
  • Witness statements, schedules of loss or threshold documents
  • Any prior expert reports
  • Court order granting permission to instruct (family / Court of Protection)

Overview

Probate disputes about testamentary capacity require a retrospective psychiatric assessment of a person who is, by definition, no longer available for examination. The opinion must be built from contemporaneous GP and hospital records, witness statements, the will file and any solicitor's attendance notes.

We instruct old age psychiatrists and neuropsychiatrists with substantive experience of retrospective capacity work and of giving evidence in the Chancery Division and County Court probate lists.

Legal framework

Reports apply the Banks v Goodfellow test for testamentary capacity, the Mental Capacity Act 2005 where appropriate, and the principles in Re Loxston / Walker v Badmin.

Psychiatric issues addressed

  • Testamentary capacity at the date of execution
  • Dementia and its impact on capacity at relevant times
  • Delusional disorder and undue influence
  • Capacity to revoke or alter a will

Questions you can put to the expert

Drop any of these straight into your letter of instruction.

  • Did the testator have testamentary capacity at the relevant date?
  • Was capacity affected by dementia, delirium or psychiatric disorder?
  • Was the testator susceptible to undue influence?

Wills & probate: areas we cover

Capacity to revoke or to make a lifetime gift

We address the related but legally distinct tests for capacity to revoke a will, to make a lifetime gift, and to enter into lasting powers of attorney.

Dementia and fluctuating capacity

Where the testator had a diagnosis of dementia, the question is rarely whether they had capacity at any point but whether they had capacity on the specific date of execution. We address the trajectory of the disease and the available windows of capacity.

Testamentary capacity (Banks v Goodfellow)

Reports apply the four-limb Banks v Goodfellow test, understanding the nature of the act, the extent of the property, the claims of those who might expect to benefit, and the absence of any disorder of the mind that perverts the disposition. We address each limb separately and against the contemporaneous evidence.

Undue influence

Reports address whether the testator's mental state, through depression, dependency, delusional disorder or cognitive impairment, made them susceptible to undue influence at the relevant time.
