# Worksheet before a personal injury costs update

> Internal worksheet completed before a personal injury costs update is sent. The lawyer marks the state, whether the change meets that state's test, and whether a different letter should be used instead.

## When to use it

Complete it before the costs update notice and the revised estimate go to a personal injury client in New South Wales, Victoria or Queensland. It does not leave the firm. It does not replace either letter.

## Used for these tasks

- [Update the costs disclosure after a significant change to the estimate](https://ailawframework.com/obligations/costs-billing-and-litigation-funding/update-the-costs-disclosure-after-a-significant-change-to-the-estimate.md)

## How AI may be used

The tool can open the worksheet and repeat the last estimate from the file. The lawyer marks the test for that state and whether this update, the library letter, or neither, is sent.

**AI may:**

- Enter the date of the last disclosure from the file
- List the injury items that have moved, without amounts, until the lawyer adds them
- Flag a threshold question as one that goes to the library letter

**AI must not:**

- Must not mark the change as significant or as substantial
- Must not choose which letter is sent
- Must not fill the Uniform Rules threshold amounts

**The lawyer checks:**

- A disclosure was already made, so that section 174(1)(b) or section 315 is the section being considered
- The significant-change box is used only on a New South Wales or confirmed Victorian file
- The library significant-change letter is not ticked for the same change as this update
