## When to use it

Use when a party in a US district court will ask the clerk to tax costs after judgment and will file the current AO 133. The declaration is the claiming lawyer's. Do not use this note to choose which items are taxable.

## How AI may be used

The tool may list the cost headings printed on the opened bill, and it must not enter an amount, an item or the perjury declaration.

**AI may:**

- List the headings that appear on the opened PDF so the lawyer can mark which categories the judgment file actually contains
- Remind the lawyer that the form requires service of a copy, and that no rule deadline was opened with this form

**AI must not:**

- Must not enter any dollar amount or describe any cost item
- Must not declare that a cost was necessarily incurred or that a service was necessarily performed
- Must not draft the perjury declaration or the service certificate
- Must not state a filing deadline. No rule stating a number of days was opened for this form

**The lawyer checks:**

- The form page gives the form number AO 133, updated on 16 July 2024, effective on 1 December 2009. The PDF linked from that page was opened
- The bill asks the clerk to tax costs after judgment entered on a stated date against a stated party. A special note says to attach an itemisation and documentation for requested costs in all categories
- The declaration reads: "I declare under penalty of perjury that the foregoing costs are correct and were necessarily incurred in this action and that the services for which fees have been charged were actually and necessarily performed."
- The same declaration says a copy has been served on all parties, by electronic service, first class mail with postage prepaid, or other. The signature block on the opened extract is "s/ Attorney" and "Name of Attorney"
- Headings visible on the opened extract include clerk's fees, transcripts necessarily obtained for use in the case, printing, witness fees itemised on page two, exemplification and copies, costs on a court of appeals mandate, and compensation of court-appointed experts. One heading is cut off. Do not finish it
- Do not add a 14-day deadline or a citation to 28 U.S.C. § 1924. Neither was on the pages opened for this form
