Interrogatory Answers That Don't Come Back to Bite You

Of all the documents a PI case generates, interrogatory answers have a special property: they're sworn, permanent, and designed to be quoted back. A demand letter is advocacy; a deposition at least allows "as I sit here today." But the verified interrogatory answer is your client's testimony, drafted at leisure, signed under oath — and every word of it is available to opposing counsel for the life of the case, including the afternoon your client is on the stand.

Which is why the scariest discovery problems aren't the late responses. They're the inconsistent ones — answered honestly, served on time, and quietly different from what the client said somewhere else. Here's how that happens, what it costs, and the discipline that prevents it.

How honest answers go wrong: a fictional cautionary tale

Meet our recurring fictional client Maria one more time. At intake, she told the office she missed "about three weeks" of work. The ER record says she was "unable to work — duration unknown." Her recorded statement to the carrier, given before she had counsel, says "a couple of weeks, maybe." The wage-loss documentation eventually verified 19 working days. And the interrogatory answer — drafted at month eight by a busy attorney working from the intake memo — says "approximately one month."

Every version is honest. Nobody lied. And at deposition, defense counsel now has four versions of one fact to walk Maria through, one of them sworn — and after five minutes of "which is it, Ms. M—?" the jury question isn't about wage loss anymore. It's about whether anything this witness says holds still.

That's the mechanism, and notice what caused it: not dishonesty, not even carelessness on any single document — just nobody assigned to read the documents against each other before the sworn one went out.

The discipline: answers drafted against the file, not from memory

The fix is unglamorous and completely reliable: before any interrogatory answer is verified, every fact in it gets checked against every place that fact already exists. In practice that means drafting against a source map:

The client's prior statements — intake notes, recorded statements, prior affidavits. The medical record — and here the chronology earns another dividend: a timeline that already flags version drift between providers (covered in the last post) is most of the consistency check pre-built. Prior discovery in this case — earlier answers, deposition testimony if any, responses to requests for admission. The damages documentation — wage records, bills, the demand package itself; the demand your office served is a prior consistent (or inconsistent) statement too.

Every divergence found gets flagged — not resolved, flagged, because resolving it is judgment: sometimes the right move is correcting the record, sometimes qualifying the answer ("approximately," anchored to the verified documentation), sometimes the divergence signals a real factual problem the attorney needs to run down before answering at all. The flag memo — "intake says 3 weeks; ER says unknown; wage records verify 19 days; recommend answer track wage records" — is the deliverable. The decision on it is the attorney's, always; sworn answers sit firmly on the judgment side of the line this series drew in month one.

Two structural habits that prevent the problem upstream

Answer from documents, not recollection. The drafting shortcut that creates drift is working from the intake memo or the attorney's memory of the file. The discipline is mechanical: every factual assertion in an answer carries an internal citation to its source document in the draft (stripped before service). If an assertion can't be cited, that's not a drafting problem — that's a fact nobody has verified yet, surfaced at the best possible time.

Treat supplements as first-class drafting. Cases move; answers served at month eight are stale by month fourteen, and the duty to supplement is also an opportunity — the supplement gets the same against-the-file check, and inconsistencies caught at supplement time can often be repaired cleanly rather than exploited later.

Where this fits in the delegation map

Regular readers will recognize the shape: this is the discovery triage post's "assembly layer," at its highest-stakes point. The source-mapping, the cross-reading, the flag memo — that's paralegal-layer work, hours of document cross-reference that no busy attorney should spend a midnight on and no careful firm should skip. The qualification, the strategy, the verification — attorney work, untouchable.

Interrogatory answers don't need to be brilliant. They need to be consistent — and consistency, it turns out, is a deliverable.The cost math, sharpened

The cost math is the usual one, but sharper here: the cross-check on a set of answers is a few paralegal-hours at paralegal rates. The cross-examination it prevents is priced in case value.
