A prior inconsistent statement is something a witness said before trial — in a deposition, a written statement, an interview, or elsewhere — that contradicts what they are now testifying to. It is one of the most common and effective impeachment tools because it lets the jury directly compare what the witness said then against what they are saying now.

In many jurisdictions, a prior inconsistent statement is admissible only to impeach credibility, not as substantive proof of the fact asserted, unless it meets additional conditions such as being made under oath in a prior proceeding. The distinction matters because a jury instructed to consider a statement only for credibility, not truth, may treat the same words very differently than if the statement were admitted as substantive evidence.

Because deposition transcripts are a primary source of prior statements, Juricratic's evidence record links a witness's deposition testimony directly to any later trial or declaration testimony on the same topic, so a contradiction becomes visible in the case file rather than something counsel has to rediscover by re-reading old transcripts.

Litigators comb deposition transcripts, written discovery responses, and prior filings for statements that may later conflict with trial testimony, and prepare the specific page-and-line citations needed to confront a witness efficiently at trial. Spotting a prior inconsistency early can also shape settlement leverage well before trial.
