What Is Washington ER 1002?

Washington ER 1002 is the evidence rule that mandates the use of the original writing, recording, or photograph when a party seeks to prove the content of that item in court. This is often called the “original document rule,” and it plays a crucial role in the admissibility of evidence in Washington courts.

According to the rule, duplicates or summaries may not be enough—especially when the content itself is in dispute. Understanding Washington ER 1002 is vital for attorneys and litigants preparing for trial.


When Is the Original Required in Washington Courts?

Under ER 1002, an original document is required when a party seeks to prove its contents. This applies to writings, recordings, or photographs and prevents alterations or misrepresentations from being presented in court.

For example, if you are introducing a written contract, video footage, or a signed statement, Washington courts expect the original version unless an exception applies under another rule.
