Preventing Disaster Revictimization Act This bill requires the Federal Emergency Management Agency (FEMA) to waive certain debts owed to the United States related to disaster assistance provided to an individual or household. Specifically, FEMA must waive a debt owed to the United States related to disaster assistance provided to an individual or household if such assistance (1) was distributed based on an error by FEMA and such debt is construed as a hardship, and (2) is subject to a claim or legal action. FEMA must report to Congress on (1) actions that it will take to reduce the error rate, and (2) the internal processes used to make decisions regarding the distribution of federal disaster assistance to individuals and households and any changes made to such processes.
