§ 2903 Subscribing witness' testimony unnecessary.

If a document has a witness who signed it to confirm it's real, you don't need to bring that witness to court to testify. The document can still be used as evidence without them.

The only exception is if the specific laws that govern whether the document is valid require witness testimony. In that case, you would need to get the witness to testify. But in most situations, you can skip this step and rely on other ways to show the document is authentic.
