What type of document best represents the collection of client information and case details?

An Intake Memo is specifically designed to gather and summarize a client's information and the details of their case at the initial stages of representation. This document typically includes vital information such as the client's personal data, the nature of the legal issue, any relevant facts presented by the client, and potential legal claims or defenses. Since it is created early in the legal process, it serves as a foundational document that provides critical context for the attorney and paralegal in managing the case.

In comparison, a case file generally contains a collection of all documents related to a case, but it is broader and evolves over time as new information and documents are added. A client agreement outlines the terms of the relationship between the attorney and the client, such as fees and services, but does not focus on gathering detailed case information. A legal brief is a more structured document used to present arguments and legal reasoning to a court, rather than to collect initial information. Thus, while each of the other options serves an important purpose, none fulfill the specific role of summarizing and collating client information and case details as thoroughly as an Intake Memo does.
