A defense economist pulls the plaintiff's last three tax returns, averages the wages, projects them to a retirement age, and calls that the economic loss. On paper it looks tidy. But the decedent was 34, two years into a trade, and had just finished an apprenticeship that would have moved her into a higher pay grade within months. The W-2 history understates what she was on track to earn, and an economist working from wage records alone has no foundation to say otherwise. That gap, between what someone earned and what they were realistically going to earn, is where a wrongful death vocational expert in California does the work the economist cannot.
Vocational experts are often the quietest piece of a catastrophic-injury or wrongful-death damages model, and the most decisive. They build the factual record about a person's earning capacity that the economist later reduces to present value. Get the vocational foundation wrong, and the economic number sits on sand. Get it right, and you have testimony that survives a motion to strike and reads as common sense to a jury.
What a vocational expert actually does in a damages case
An economist answers a math question: given a stream of expected earnings, what is it worth today? A vocational expert answers the harder upstream question: what was this person realistically going to earn, for how long, and in what occupations? The two roles are distinct, and conflating them is a common reason damages testimony gets challenged.
In a wrongful-death claim, the vocational expert reconstructs the decedent's earning capacity as it existed at the time of death. That means looking past the most recent paycheck to the full picture: education, certifications, licenses, work history, the trajectory of recent promotions, the labor market for that occupation, and the person's documented plans. A young worker mid-career, a tradesperson moving toward a journeyman wage, a small-business owner whose income was reinvested rather than drawn, all present earnings pictures that raw wage records distort.
In a catastrophic-injury claim where the plaintiff survives, the analysis runs in two parts. The expert establishes pre-injury earning capacity, then assesses what the person can still do given the new physical or cognitive limitations. The difference between those two figures, framed in terms of occupations the plaintiff can and cannot perform, is the vocational basis for the lost earning capacity claim.
Earning capacity is not the same as earnings
The distinction matters in California. Earnings are what someone made. Earning capacity is what someone was able to make, used or not. A parent who left the workforce to raise children, a recent graduate with credentials but a thin work history, a worker who took a lower-paying job for personal reasons, each had earning capacity that their recent income does not reflect.
A lost earning capacity expert builds that figure from labor-market data, occupational requirements, and the individual's specific qualifications rather than from a single year of tax returns. The expert ties wage ranges to real occupations the person was qualified to hold, accounts for typical career progression in that field, and supports the projection with sources a court will recognize. This is what separates a defensible capacity opinion from a number that looks invented. When the methodology is transparent and grounded in published labor data, opposing counsel has far less room to argue the figure is speculative.
The same rigor matters on the duration side. How long would the person have worked? Worklife expectancy, not life expectancy, governs the earnings horizon, and a credible vocational expert addresses it directly rather than assuming work to a round retirement age.
How the vocational and economic experts fit together
Think of it as a relay. The vocational expert hands the economist a factual foundation: occupations, wage ranges, worklife expectancy, the percentage of capacity lost. The economist takes those inputs, applies present-value discounting and growth assumptions, and produces the dollar figure. If the vocational handoff is weak, the economist's polished output inherits every flaw in the foundation.
This is also where coordination between your experts pays off. When the vocational and economic experts use consistent assumptions, the testimony holds together under cross-examination. When they contradict each other, the defense will find the seam and pull on it. Retaining the vocational expert early, before the economic model is built, lets the foundation drive the math instead of the other way around.
Questions to ask before you retain
A few questions sort credible vocational experts from those who will struggle on the stand:
- What labor-market and occupational sources do you rely on, and can you produce them?
- How do you establish worklife expectancy rather than assuming a retirement age?
- Have you been excluded or limited by a court, and on what grounds?
- For an injured plaintiff, how do you assess residual capacity rather than assuming total loss?
- How do you handle a decedent or plaintiff with an atypical work history?
You are not looking for the highest possible number. You are looking for an expert whose opinion will survive a challenge to its foundation and read as reasonable to twelve people who have never thought about worklife tables. An expert who overreaches gives the defense an easy target and risks the credibility of your entire damages case.
The practical takeaway
Lost earning capacity is won or lost at the foundation, not the formula. The vocational expert builds that foundation, and your damages model is only as strong as that work, long before the economist runs a present-value calculation. In wrongful-death and catastrophic-injury cases, retaining a qualified vocational expert early and pairing them with an economist who uses the same assumptions is the difference between a damages number that holds and one that gets picked apart.
