Forensic handling of UGRs requires best practices for assessing authenticity and integrity of the recorded information.

Guardianship Abuse: Bad Apples or Tip of the Iceberg?

January 2025

When cases involving high-profile individuals, like Britney Spears, make national headlines, issues surrounding guardianship and conservatorship take center stage. But after those specific cases resolve and national interest fades, the systemic issues remain. We have very little data on how the guardianship system is actually working, and the scope and prevalence of guardianship abuse remains unclear. We don’t know how many individuals suffer abuse under guardianship. We don’t know to what extent guardianship, when properly executed, improves the lives of those it’s intended to serve.
