Bennett Blum, MD developed the IDEAL model for organizing evidence of isolation, dependency, emotional manipulation or exploitation of vulnerability, acquiescence, and loss. The model has been discussed, cited, or reproduced in professional materials from the American Bar Association and American Psychological Association, the British Columbia Law Institute, and the Judicial Council of California.
His analysis addresses evidence supporting and contradicting each proposed conclusion, reasonable alternative explanations, and the material limitations of the available record.
How Undue Influence Claims Are Evaluated
Undue influence is a legal conclusion, not a psychiatric diagnosis, and its elements vary by jurisdiction. Counsel identifies the controlling law; forensic psychiatric analysis addresses the cognitive, psychiatric, behavioral, relationship, and decision-environment evidence relevant to that law.
In litigation, undue influence claims rarely turn on a single dramatic act. More often, the central question is whether a pattern of dependency, isolation, fear, deception, emotional pressure, or exploitation caused a vulnerable person to make a decision that no longer reflected independent judgment.
Bennett Blum, MD provides consultation and selected expert-witness services to attorneys and courts evaluating these claims. His analysis addresses vulnerability, capacity, relationship dynamics, manipulation tactics, the conduct of the alleged influencer, the decision-making environment, and alternative explanations.
His work is especially relevant in probate litigation, trust and estate disputes, elder financial exploitation cases, high-value family-wealth disputes, and selected business or professional-misconduct matters.
When Forensic Psychiatric Analysis May Help
These matters are most likely to benefit from specialized analysis when counsel must reconstruct one or more of the following:
The vulnerabilities and decision-making abilities of the person alleged to have been influenced at the relevant time;
The relationship between that person and the alleged influencer;
Patterns of isolation, dependency, emotional manipulation, secrecy, or active procurement;
Whether the challenged decision was consistent or inconsistent with prior values, relationships, and intentions; and
Whether apparent consent was the product of accurate information and free choice, or of distortion, fear, dependence, or misplaced trust.
Not every undue-influence dispute requires a psychiatrist. Dr. Blum does not decide the ultimate legal question. Matters turning principally on document interpretation, asset tracing, valuation, signature authentication, fiduciary accounting, or legal ethics may require other expertise. His role is to analyze the psychiatric, cognitive, behavioral, relationship, and decision-environment evidence relevant to the governing standard.

Attorney Case Inquiries
Matters are screened for conflicts, fit, timing, complexity, and whether specialized forensic psychiatric analysis can materially assist counsel. This practice does not accept clinical, emergency, or pro se matters.
Attorneys may submit a brief, non-confidential inquiry through the Attorney Conflict Check. Do not send records, privileged communications, protected information, or detailed case strategy before conflicts are cleared and an engagement is confirmed in writing. Submitting an inquiry does not retain Dr. Blum or create a professional relationship.
