Which feature is used to create personalized letters in legal documentation?

Creating personalized letters in legal documentation is effectively accomplished through merging documents. This feature allows for the integration of a standard letter template with specific data from a database or a list of clients, making it possible to customize each letter while maintaining a consistent format.

Merging documents enables the user to input unique information such as names, addresses, and case details in designated areas of the template, which streamlines the process and enhances accuracy. This is particularly useful in a legal setting where personalized correspondence is often necessary for client communications, court notifications, or legal notices.

The other options, while they may have their respective uses, do not serve the same purpose in creating personalized letters. Page layout tools help in organizing the visual structure of a document but do not enable personalization. Text auto-fill can assist in filling in pre-defined fields but lacks the comprehensive functionality provided by merging documents. Footers are essential for including additional information at the bottom of pages, yet they do not contribute to the personalization of letters as merging documents does.
