Nunc pro tunc
Nunc pro tunc: Latin for "now for then." A court order that takes effect as of an earlier date, often to correct the record so it reflects what actually happened.

What nunc pro tunc means
Put simply, nunc pro tunc 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 nunc pro tunc comes up
For example, the term appears in these procedures:
- Motion to Correct a Clerical Mistake (Fed. R. Civ. P. 60(a)): a request to fix a clerical mistake, or a mistake arising from oversight or omission, in a judgment, order or other part of the record.
How to research the term
First, read the term where it actually appears. A rule, statute or court decision may define it for its own purposes. Next, check whether your court has a local rule that uses nunc pro tunc in a special way. Then look at recent decisions from courts in your jurisdiction. They show how judges apply the term today. Also, remember that state law can differ from federal law. For that reason, use our state procedures guide to find your state’s rules. Finally, confirm every source is current before you rely on it.
