What is “Undue Influence”

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.
