This Practice Note outlines key issues to consider when drafting and submitting proposed findings of fact and conclusions of law in federal court. Specifically, this Note identifies the purpose and scope of proposed findings of fact and conclusions of law. This Note also explains how to draft, file, and serve the proposed findings of fact and conclusions of law, and how to challenge the findings and conclusions that the court ultimately issues. Although this Note focuses on preparing proposed findings of fact and conclusions of law in federal civil actions under Federal Rule of Civil Procedure (FRCP) 52, it may also assist counsel with preparing post-trial factual findings and legal conclusions in state courts where the process is similar.
