A witness forgets. You can hand them almost anything to jog the memory. But the moment you do, the other side is entitled to see it, and that trade is the whole rule.
When a witness draws a blank on the stand, the law lets you refresh their recollection. You show them something, a report, a note, a photograph, even a document you could never put into evidence, and you ask whether it brings the memory back. If it does, the witness testifies from memory, not from the paper.
Here is the catch, and it is Texas Rule 612. Anything you use to refresh a witness’s memory while testifying, the opposing party is entitled to have produced, to inspect, to cross-examine the witness about, and to introduce the relevant parts of into evidence. What you show the witness, you show your opponent.
That is why refreshing is a decision, not a reflex. Hand a forgetful witness your privileged notes to jog the memory and you may have just handed them to the other side. The safer move is to refresh with something you were always willing to disclose, and to know, before you reach for it, exactly what becomes discoverable the instant the witness looks at it.
There is a companion doctrine worth keeping straight. Present recollection refreshed means the witness now remembers and testifies from memory; the paper is only a spark and does not come in for its truth. That is different from past recollection recorded, a hearsay exception for a record made when the memory was fresh and now gone for good. Refreshing revives a memory. It does not read a document to the jury.
So the word to carry is refresh, and the discipline is to remember the trade. You may use almost anything to bring a memory back. Just know that the moment you do, it stops being only yours.
On refreshing a witness’s memory, see Texas Rule of Evidence 612 (the adverse party’s right to production, inspection, cross-examination, and introduction of a writing used to refresh memory while testifying); compare Texas Rule of Evidence 803(5) (past recollection recorded). This is general information, not legal advice.
