A fact you believe is only worth what you can get in front of the fact-finder — or keep out of the other side’s hands.
a case’s proof by asking, of each item, two questions: can I use it, and is it protected. An oral deal can hit the statute of frauds; a written one can bar earlier oral terms under the parol evidence rule; an out-of-court statement runs into hearsay; auto-deleting data becomes a spoliation trap; and your own advice and work are shielded by privilege and work product — until a stray forward or the wrong consultant waives it. Most blockers have a principled fix. The skill is spotting which doctrine is in play, fast.
Interactive · the evidence tray
Five pieces from a contract dispute. Each has a goal. Send one toward “holds up” — a clean piece clears; a blocked one bounces back and names the doctrine. Then flip the facts below and watch specific cards turn usable.
Run each item through two questions, then reach for the doctrine and its fix:
ADMISSIBLE? can it reach the fact-finder?
PROTECTED? is it shielded from the other side?

oral deal statute of frauds -> a signed writing,
or an exception like partial performance
written deal parol evidence rule bars earlier oral terms
that contradict a final, integrated writing
out-of-court hearsay -> a recognized exception:
statement dying declaration, statement against interest,
former testimony under oath, and others
electronic data spoliation -> issue a litigation hold the moment
litigation is reasonably anticipated; stop auto-delete
advice / work attorney-client privilege + work product protect it
-> counsel-directed work; a stray forward waives it

| Fits | Keep in mind |
|---|---|
| Early case assessment — what can we actually prove? | “True” and “provable” are different questions |
| Issue-spotting on an exam or in a screening interview | Name the doctrine, then the exception — both earn credit |
| Deciding what to preserve, and what to never forward | Preservation and privilege errors are often unfixable later |
An issue-spotting screen: “We shook hands on a two-year exclusive, then texted the terms. Our outside analyst wrote a damages memo. Their key witness has since died. And the deal talks were on an app that auto-deletes. What have we got?” A strong triage runs the tray: the oral two-year term is within the statute of frauds — blocked, unless partial performance takes it out. The texts are a signed writing and the other side’s own words — usable, just authenticate them. The analyst memo isn’t privileged unless counsel directed it as work product — and don’t forward it. The dead witness’s statement is hearsay unless an exception (former testimony, statement against interest) fits. And the auto-deleting app is a spoliation trap — issue a litigation hold now. Five items, five doctrines, in about a minute.
Opposing counsel demands your outside consultant’s report. It’s protected if…
You reasonably anticipate being sued next week. The client’s chat app auto-deletes after 24 hours. First move?
