The FEMA appeal process involves filing an appeal within 60 days of receiving a decision letter from FEMA. You must provide additional documentation to support your appeal. FEMA will review your appeal and make a decision within 90 days. You will have one additional attempt at an appeal regarding the decision FEMA sent to you. You MUST provide additional documentation that can challenge the negative decision from the initial appeal. After this second attempt, you can appeal one more time, but only if policies or procedures were not followed by FEMA. The entire appeals process can take more than 12 months in some cases. It is essential to retain all copies of documents, including FEMA-related paperwork, in case their database is purged before your appeal is finalized.
