Abstract
As the population of the USA ages, mental health practitioners are increasingly called upon to assess civil capacities. This paper provides information regarding the assessment of testamentary capacity and the related issue of undue influence. A brief review of the legal standards that inform these types of assessments is provided, including a discussion of the Goodfellow legal criteria and the relationship between delusional thinking and validity of will or trust. This paper reviews methods for performing these types of assessments with both living and deceased testators, including a general overview of methodology, suggestions for test choice and use, and the expert’s role in probate court. The overuse of inappropriate psychometric instruments is also discussed. Common problems with assessments and testimony in this area of practice, such as the conflation of diagnosis and functional capacity, and misunderstanding of the applicable legal standards, are reviewed. This paper concludes by suggesting that the courts and mental health professionals may be working at cross purposes in this area of practice.
