## Key facts

| Fact | Value |
| --- | --- |
| Practice area | [Commercial Litigation & Dispute Resolution](https://ailawframework.com/practice/commercial-litigation-and-dispute-resolution.md) |
| Human involvement | Yellow: Lawyer and AI draft together |
| How AI is used | From the invoices the lawyer marks, list the item, the amount, and the 28 U.S.C. § 1920 category the lawyer assigns. Do not predict what the clerk will tax and do not call the proceeding a registrar's estimate. |
| What the lawyer must review | Federal Rule of Civil Procedure 54(d)(1) provides that the clerk may tax costs on 14 days' notice, and that the court may review the clerk's action on a motion served within the next 7 days. 28 U.S.C. § 1920 is the list of items a judge or clerk of a court of the United States may tax as costs. The Federal Rules text opened here does not provide for a registrar's estimate of a bill of costs. The working list is for the lawyer who will address the clerk's taxation. Local rules may set how a bill is presented. The lawyer reads those rules. |

## Checking plan

- What the AI does: From the invoices the lawyer marks, list the item, the amount, and the 28 U.S.C. § 1920 category the lawyer assigns. Do not predict what the clerk will tax and do not call the proceeding a registrar's estimate.
- Basis: Checked against the linked sources on 22 October 2026. Confirm the current instrument before reliance.

## Notes

- There is no federal registrar's taxation in Rule 54(d). Do not use that title on the list.
- The category on each row is the one the lawyer assigns. The tool does not choose it.
