For most of my career, I have helped families, business owners, and professionals make important financial decisions. Occasionally, however, I am asked to step into a very different role—that of an expert witness in family law and other civil litigation.
People often assume that expert witness work is primarily technical. It certainly requires technical competence. One must understand life insurance, executive benefits, retirement plans, actuarial principles, taxation, valuation, and just simple math. But those are merely the tools. The real work lies elsewhere.
An expert witness occupies a unique ethical position. Unlike an advocate, my responsibility is to help the trier of fact understand the truth as objectively as possible. Sometimes that truth favors the party who retained me. Sometimes it does not. Professional integrity requires that the opinion remain the same regardless of who signs the engagement letter.
That obligation has reinforced something I have long believed: ethics is not demonstrated when telling the truth is easy. Ethics is demonstrated when objectivity conflicts with financial interest, personal loyalty, or the expectations of the client.
Family law presents some of the most emotionally charged disputes in our legal system. Assets are not merely numbers on a balance sheet; they represent years of work, sacrifice, expectations, and often disappointment. Insurance policies become symbols of security. Retirement plans become symbols of fairness. Business interests become extensions of personal identity. In that environment, emotion naturally competes with reason.
The role of the expert is not to eliminate emotion. That would be impossible—and perhaps undesirable. Divorce involves real people experiencing genuine loss. Compassion matters. But compassion cannot replace analysis. The most compassionate opinion is not necessarily the one that benefits the person sitting across the table. Sometimes genuine compassion requires delivering an opinion that someone would rather not hear because it is supported by the facts.
This principle has become central to my understanding of professional responsibility. Respecting another person's autonomy does not require validating every belief or expectation they hold. A physician does not serve a patient by ignoring a diagnosis. An attorney does not serve a client by concealing legal weaknesses. Likewise, a financial expert does not serve the court—or the client—by shaping opinions to fit a preferred narrative.
The pursuit of truth requires intellectual independence.
That conviction also reflects a principle from Objectivist philosophy that has influenced my thinking throughout my life: reality exists independently of our wishes. Facts are not altered by emotion, advocacy, or repetition. A life insurance policy has a value independent of what either spouse hopes it is worth. Mortality does not yield to optimism. Tax law does not bend to fairness. Professional integrity begins by recognizing that reality is not ours to negotiate.
It is equally consistent with the concept I have developed in my own research, Rational Paternalism. Professionals are entrusted with specialized knowledge not merely to answer questions but to exercise informed judgment. The ethical obligation is not passive neutrality. It is to apply competence honestly, explain conclusions clearly, and help decision-makers avoid conclusions unsupported by the evidence. Whether advising a client, teaching students, or assisting a court, the responsibility remains the same.
Over the years, I have discovered that expert witness work is less about testifying than listening. Before offering an opinion, one must understand not only the documents, but the context in which they exist. Every file tells a story. Every financial decision has a purpose. Every opinion carries consequences.
In the end, credibility is an expert's most valuable asset. It cannot be purchased, delegated, or manufactured. It is earned one opinion at a time, by remaining faithful to the evidence even when doing so is inconvenient.
That, to me, is what professionalism looks like.
