A more thorough explanation:

An errata sheet is a document that contains corrections made by a deponent after reading a deposition transcript. It is also known as an errata page. The purpose of an errata sheet is to ensure that the transcript accurately reflects the deponent's testimony.

After reading the deposition transcript, the deponent noticed that their name was misspelled. They would submit an errata sheet to correct the spelling of their name.

Another example would be if the deponent noticed that they made a mistake in their testimony. They would submit an errata sheet to correct the mistake and provide an explanation for the correction.

These examples illustrate how an errata sheet is used to correct errors or mistakes in a deposition transcript. It is important for the accuracy of the transcript and to ensure that the deponent's testimony is properly recorded.
