A more thorough explanation:

Definition: Attorney's work product refers to written materials, notes, charts, and other documents that are created by an attorney or their team during the preparation of a case or legal representation. These materials are considered important because they cannot be required to be introduced in court or revealed to the other side. However, there may be a question as to whether the documents were prepared by the attorney or the client for use in the case preparation or are independent and legitimate evidence.

Example: An attorney is preparing for a trial and creates a chart that outlines the key points of their argument. This chart would be considered attorney's work product and would not be required to be shared with the other side.

Example: During an investigation, an attorney takes notes on their conversations with witnesses. These notes would also be considered attorney's work product and would not be required to be shared with the other side.

These examples illustrate how attorney's work product can include a variety of materials that are created during the preparation of a case or legal representation. These materials are considered important because they allow attorneys to prepare their case without fear of having to reveal their strategy or evidence to the other side.
