When to bring an expert into the case

The second cost is the one that does real damage, and it is invisible until it lands. Counsel forms a working theory from the client's account and the initial records, builds the pleading around it, takes discovery consistent with it, and brings in an expert to confirm it. When the expert reads the imaging or the claim file or the daily reports and says the theory does not hold, months of work were spent in a direction the evidence never supported.

An early review is a comparatively small cost against that. It is also the stage at which an expert is most useful, because the answer can still change something.

The last is the most commonly skipped and the most valuable. Every contested matter has a competing account — the degenerative changes predate the collision, the failure was maintenance rather than design, the adjuster's investigation was adequate given what was reported. An expert who identifies it early lets counsel decide whether to meet it, work around it, or reassess the matter.

Early review also identifies missing material while it can still be obtained. A causation opinion that needs pre-incident imaging, a safety opinion that needs the inspection file, a claims opinion that needs the insurer's guidelines — each is straightforward to request during discovery and very difficult to conjure afterwards.

The distinction worth drawing is between a screening conversation and a substantive review. A screening conversation — what would an opinion in this discipline be built from, does this look like a matter that needs one, what should we be asking for in discovery — costs nothing here and is almost always worth having at the outset.

The substantive review should wait until the material it depends on exists. Ordering it against a partial production means either a preliminary view that will have to be revisited, or a review of the same records twice.

Washington's disclosure runs on the case schedule issued in the matter rather than a statewide structure, so the operative order determines the real date and there is no general rule to rely on. Oregon's expert discovery practice is structured differently again, which raises the value of getting a candid assessment early rather than relying on a fuller pre-trial sequence to surface problems.

This site does not calculate any deadline. The general point holds regardless of jurisdiction: the useful moment to involve an expert is while the answer can still change what you do.
