A forensic report is the document a deposition is actually fought over: not the underlying facts, which rarely change once the investigation is complete, but whether the report's reasoning holds up line by line. Attorneys who read a report the way it was written (start to finish, for the narrative) miss the places opposing counsel will actually press. Reading it the way a hostile examiner will is a different exercise.
- 1. Does the stated methodology actually match what the report describes doing? If a report cites a testing standard (ASTM E2128, for instance, as the framework for a water-intrusion investigation), check that the steps described in the body actually follow that standard's sequence. A methodology citation that doesn't match the described process is one of the fastest ways a report's credibility gets undermined at deposition.
- 2. Is every conclusion traceable to a specific, cited piece of evidence? A strong report reads like a chain: observation, test result, or document citation, leading to a conclusion. A weak spot is any conclusion that seems to rest on the expert's general experience rather than something documented in the file. That's not automatically a problem (expertise is part of what's being paid for), but it's exactly the kind of statement opposing counsel will ask to be justified on the record, so it's worth knowing which conclusions have that shape before the question is asked live.
- 3. Does the report address the obvious alternative explanation, or just the one it concludes? A report that never mentions an alternative cause a reasonable opposing expert would raise reads as one-sided even when the conclusion is correct. Check whether alternative causation was considered and ruled out in the report itself, or whether that analysis only exists in the expert's head; if it's the latter, that's worth developing before deposition, not during it.
- 4. Are the photographs and exhibits doing the work the text says they're doing? Pull up every photo the report cites as support for a specific finding and confirm it actually shows what the caption claims. Mismatches are usually innocent (a mislabeled exhibit number, a photo swapped during editing), but they're also exactly the kind of small, findable error that can be used to suggest carelessness extends further than it does.
- 5. Does the qualifications section actually support opining on every issue in the report? If the report addresses both structural and moisture-related findings, confirm the expert's stated qualifications cover both areas, not just the one they're best known for. A gap here doesn't necessarily disqualify the opinion, but it's a predictable line of cross-examination worth having an answer ready for.
None of this is about whether a report's conclusions are right: it's about whether the report, as written, can withstand the kind of question-by-question pressure a deposition actually applies. The best time to find a weak spot is during report review, not while the expert is on the stand.
