Can a deficient expert disclosure in a Utah divorce be harmless even after the opposing party forgoes discovery? Paulson v. Paulson Explained

Summary

Christopher Paulson appealed multiple rulings entered during divorce proceedings with Trishna Paulson, including the exclusion of his financial expert witness, sixteen partial summary judgment orders classifying various assets as Trishna’s separate property under a premarital agreement, the denial of attorney fees, and the denial of his motion to disqualify the trial judge. The trial court had excluded Christopher’s expert on the ground that his rule 26 disclosure was deficient and that Trishna was harmed by having forgone her discovery options in reliance on that deficiency, then granted summary judgment against Christopher on alimony for lack of expert evidence. After twenty-six years of marriage and extensive litigation, the court also found Christopher had sufficient funds to pay his own attorney fees and that the premarital agreement foreclosed any claim against Trishna’s separate property for fees.

Analysis

Background and facts

Christopher and Trishna Paulson married in 1992 after signing a premarital agreement governed by California law that classified virtually all property acquired during the marriage as the acquiring spouse’s separate property, with cash salary as the sole community asset. After twenty-six years of marriage and a 2018 divorce petition, extensive litigation followed over sixteen parcels of property, Christopher’s alimony claim, attorney fees, and a motion to disqualify the trial judge. The trial court excluded Christopher’s financial expert under Utah Rule of Civil Procedure 26 for a deficient disclosure, then granted summary judgment against his alimony claim for lack of evidence of financial need. It also denied attorney fees, reasoning that Christopher had access to over $1.2 million in funds and that the premarital agreement barred any claim against Trishna’s separate property.

Key legal issues

The court addressed four distinct issues: (1) whether the expert disclosure was deficient under rule 26 and, if so, whether the deficiency was harmless; (2) whether Trishna’s commingling of separate funds in the joint account, the joint titling of assets, or the exhaustion tracing methodology warranted reversal of the property classifications; (3) whether the premarital agreement barred a statutory attorney fees award under Utah Code section 81-1-203(1); and (4) whether the trial judge’s prior attorney-client relationship with a lawyer at opposing counsel’s firm created an appearance of bias requiring disqualification.

Court’s analysis and holding

The court affirmed that Christopher’s expert disclosure was deficient—listing only broad topic categories rather than a summary of opinions and case-specific data as required by rule 26—and rejected his attempt to distinguish RJWMedia Inc. v. Heath on the ground that it addressed non-retained experts. However, the court reversed the exclusion as an abuse of discretion on harmlessness: Christopher had provided a complete expert report three weeks after his disclosure and offered to allow deposition, and no trial date had been set given COVID-19 restrictions. The resulting summary judgment on alimony was also reversed. On property issues, the court affirmed all sixteen partial summary judgments, holding that Christopher failed to meaningfully engage with the trial court’s reasoning on commingling, transmutation under California Family Code section 852(a), and exhaustion tracing—each argument was either inadequately briefed or unpreserved. The court also held that the premarital agreement could not be read to bar attorney fees under section 81-1-203(1), which rests on the court’s equitable power rather than community property law, and that the trial court abused its discretion by counting funds already applied to Christopher’s living expenses, the rental value of the marital home, and amounts ordered repaid to Trishna as available to pay attorney fees. The denial of the disqualification motion was affirmed because, once the prior attorney-client relationship had ended, no reasonable person would perceive an appearance of bias from a co-firm attorney’s later representation of the opposing party.

Practice implications

Practitioners should serve complete rule 26 expert disclosures from the outset, but this decision confirms that prompt remediation—delivering a full report and offering deposition access before a trial date is set—can defeat a sanctions motion. Counsel opposing a deficient disclosure should carefully weigh whether forgoing discovery options creates a strategic risk that a court will later find the violation harmless. On attorney fees, Paulson reinforces Krajeski v. Krajeski‘s holding that the separate or marital character of disputed assets is irrelevant to a section 81-1-203(1) award, and clarifies that only funds genuinely available—not those earmarked for expenses or ordered repaid—may be counted against a claimed need. Finally, practitioners pursuing transmutation arguments under a California-law premarital agreement must cite authority explaining why standard transaction documents satisfy the express declaration requirement of California Family Code section 852(a); conclusory assertions will not suffice.

Outcome

Affirmed in part and Reversed in part

Holding

A deficient expert disclosure under Utah Rule of Civil Procedure 26 is harmless where the disclosing party promptly provided a complete expert report and offered to allow deposition before any trial date was set, and the trial court exceeds its discretion in excluding the expert on those facts; additionally, a premarital agreement limiting separate property obligations cannot be read to bar a statutory attorney fees award under Utah Code section 81-1-203(1), and the trial court abuses its discretion by counting funds already designated to satisfy a spouse’s living expenses or ordered repaid to the other party as amounts available to pay attorney fees.

Standard of Review

Expert exclusion under rule 26: abuse of discretion, so long as the court applies the correct law (Phillips v. Skabelund). Summary judgment on property classification: no deference to the trial court’s legal conclusions; appellate court determines whether the court erred in applying governing law and whether material facts were genuinely disputed (Kouris v. Utah Highway Patrol). Attorney fees in domestic cases: abuse of discretion (Wollsieffer v. Wollsieffer). Motion to disqualify trial judge for bias: correctness (State v. Boyer).

Practice Tip

When opposing a deficient expert disclosure, promptly elect to receive a report or depose the expert rather than forgoing those options strategically—Utah courts may find the disclosure violation harmless if the disclosing party cures the deficiency before the sanctions hearing, particularly when no trial date is imminent.
