Clearly erroneous

Clearly erroneous: The standard for reviewing a trial judge's findings of fact. Under Federal Rule of Civil Procedure 52(a)(6), findings of fact must not be set aside unless clearly erroneous, with due regard for the trial court's opportunity to judge the witnesses' credibility.

What clearly erroneous means

Put simply, clearly erroneous is part of the working vocabulary of a civil case. The short definition above covers the usual meaning. Still, a specific rule, statute or contract can give it a narrower meaning. For that reason, check how it is used in your own documents.

Where clearly erroneous comes up

For example, the term appears in these procedures:

  • Motion to Amend Findings (Bench Trial) (Fed. R. Civ. P. 52(b)): a request, after a trial without a jury, that the court amend its findings of fact or make additional findings, and amend the judgment accordingly. The motion may accompany a motion for a new trial under Rule 59.

How to research the term

Start with the primary source. For example, if clearly erroneous appears in a federal rule, read the rule itself and its official notes. After that, check your court’s local rules and any standing orders from the judge. In addition, search recent decisions from your own state or federal district. They show how courts read clearly erroneous in practice. Because state rules often differ, our state procedures guide links to each state’s official rules. Above all, make sure the version you read is still in force.

Why precise terms matter

Legal words often look like everyday words, but they can carry a precise meaning. Because of that, a small misreading can change how you understand a deadline, a duty or a right. Our glossary keeps each definition short and links it to the procedures where it matters.
