In my work as a geriatrician and former Chief Medical Officer, I am frequently asked to evaluate whether an older adult had the cognitive capacity to execute a will, trust, power of attorney, real estate contract, or other legally binding document. These cases often arise during disputes among family members, challenges to estate plans, or allegations of undue influence.

What many attorneys discover is that capacity is not a simple yes-or-no issue, and it cannot be assessed by intuition or limited observations. Capacity determinations require a deep understanding of cognitive aging, medical conditions that affect thinking, and the way specific decisions interact with those impairments. That is where my expertise as a geriatrician becomes essential.

Capacity Is Not Intelligence — It Is a Medical State

One of the biggest misunderstandings I encounter is the assumption that capacity equals intelligence or education. In reality, capacity is a medical and functional determination based on whether an individual can:

  1. Understand the nature and purpose of the document
     
  2. Appreciate the consequences of signing it
     
  3. Reason through available options
     
  4. Communicate a clear, consistent choice
     
  5. Do so free from coercion or manipulation
     

These elements form the foundation of testamentary or contractual capacity.

 

Why Cognitive Impairment Complicates Legal Decisions

Cognitive decline rarely happens all at once. In many cases I review, the person had:

  • Early dementia
     
  • Mild cognitive impairment (MCI)
     
  • Delirium during a hospitalization
     
  • Recent medication changes
     
  • Depression or anxiety affecting cognition
     
  • Vision or hearing deficits impacting comprehension
     
  • Fluctuating lucidity (“sundowning”)
     

Even a highly educated adult can struggle to understand a will if their short-term memory is impaired or if executive-function deficits affect judgment.

Older adults with dementia may sound conversationally normal while lacking the deeper reasoning needed to execute a legal document. A brief interaction is not enough to assess this.

 

Why Attorneys Bring Me Into These Cases

Attorneys often retain me when:

  • A will was changed close to the individual’s death
     
  • A new caregiver or family member benefited unexpectedly
     
  • A client had a known diagnosis of dementia
     
  • Medical records show confusion near the time of signing
     
  • There are competing claims of lucidity vs. incapacity
     
  • A lawyer or notary sensed something “felt off”
     
  • A hospitalization or illness occurred around the signing date
     

In each of these situations, I’m asked to determine whether the person possessed the required cognitive abilities at that specific moment.

 

My Forensic Process for Determining Capacity

My role is to reconstruct the person’s cognitive state using a structured medical approach:

1. Review of All Medical Records

This includes primary-care notes, hospital records, memory-clinic evaluations, emergency-room visits, neurology consultations, and medication lists. Even subtle comments like “not themselves today” or “mild confusion noted” may be significant.

2. Cognitive Testing Data

I evaluate MMSE, MoCA, SLUMS, neuropsychological assessments, and functional questionnaires. I correlate scores with known disease trajectories.

3. Timeline Reconstruction

I pinpoint the person’s medical status on the day the document was signed, looking for delirium, infection, dehydration, anesthesia effects, or recent falls.

4. Functional and Behavioral Observations

Statements from attorneys, witnesses, family, caregivers, or notaries often provide critical context.

5. Differential Diagnosis

I determine whether observed deficits were due to dementia, delirium, depression, medications, or reversible medical conditions.

6. Application to Legal Standards

I map the medical findings to the appropriate legal threshold for testamentary or contractual capacity. These thresholds are different, and understanding the distinction is vital in litigation.

 

Why Capacity Evaluations Require a Geriatrician

After more than 40 years of clinical practice, I can often identify nuances that general practitioners or psychologists may overlook—especially the fluctuating nature of cognition in older adults. As a former Chief Medical Officer, I also understand documentation patterns, system failures, and how medical teams record subtle cognitive concerns.

My goal is to provide attorneys with an objective, medically grounded opinion about whether the individual could reasonably understand and execute the document at the time it was signed.

If you are litigating a case involving testamentary capacity, contractual competence, or allegations of undue influence, I can help provide clarity through an evidence-based, geriatric medical analysis.
