Elder financial exploitation is the largest category of property crime in America that almost never gets prosecuted, and the reason is that most of it is committed by someone the victim loves. This article explains how it actually happens: not usually as a dramatic theft but as a slow conversion of accounts, deeds, and beneficiary forms by a person holding lawful authority. It distinguishes the two families of exploitation — the stranger scam and the trusted insider — and explains why the second is far more costly and far harder to unwind. It covers the legal instrument most often abused, the durable power of attorney, and why it is both indispensable and dangerous. It explains undue influence as courts actually analyze it, the evidence that proves it, and the remedies that reverse it. It covers reporting to adult protective services, the role banks now play, criminal referral, and the civil actions that recover money. It closes with the prevention measures that actually work and the ones that only sound good.
