Mental Capacity and Testamentary Capacity
Expert Witness and Litigation Consultant
Questions of capacity sit at the center of will contests, trust disputes, guardianship and conservatorship matters, contested transactions, business disputes, settlements, gifts, and other high-stakes decisions. Capacity is not a single global trait. It is decision-specific, time-specific, and fact-specific.

Common Litigation Questions
Did the person understand the nature and consequences of the decision at the relevant time?
Was the decision affected by dementia, delirium, psychiatric symptoms, substance use, medication effects, grief, dependency, fear, or cognitive impairment?
Was capacity impaired enough to affect a will, trust, gift, contract, settlement, or financial transaction?
Was the person vulnerable to undue influence even if some capacity remained?
Can capacity be reconstructed retrospectively when the individual has died or can no longer be examined?
Understanding Mental Capacity in Litigation
Capacity is not a single, fixed trait. It is decision-specific and time-specific: a person may have the capacity to make one kind of decision but not another, and capacity can fluctuate with illness, medication, and cognitive decline. Courts require proof that the relevant standard was or was not met at the specific moment the decision was made.
Retrospective Capacity Analysis
When the person can no longer be examined, the analysis must be reconstructed from the contemporaneous record. Dr. Blum evaluates medical documentation, behavioral evidence, witness accounts, records of the transaction, and the clinical plausibility of lucidity or impairment at the relevant time.
