About Bennett Blum, MD
Bennett Blum, MD is a forensic and geriatric psychiatrist whose work focuses on undue influence, mental and testamentary capacity, elder financial exploitation, coercion, consent, and vulnerability to manipulation.

What is “Undue Influence” in Litigation?
Undue influence occurs when someone misuses trust or authority to control the decisions of a vulnerable person for personal gain. It often appears in cases involving elder abuse, family disputes, financial exploitation, or professional misconduct, where manipulation replaces free will.
Dr. Bennett Blum specializes in identifying and explaining how undue influence develops, how it affects victims, and how it can be proven or disproven in legal settings.

Attorney Case Inquiries
Dr. Blum accepts a limited number of selected matters. Priority is given to cases that are complex, high-stakes, or likely to clarify important issues for a court, institution, family, or vulnerable population.
Attorneys may submit a non-confidential case inquiry through the Contact page. Do not send confidential materials, protected information, records, pleadings, discovery, or documents until conflicts have been checked and a written engagement agreement is in place.
Submitting an inquiry does not retain Dr. Blum, does not create a physician-patient relationship, does not create an expert-consultant relationship, and does not preclude Dr. Blum from being retained by another party unless and until a written engagement agreement is signed.
