Case Brief – Marriage of Zucker

Court: COURT OF APPEAL OF THE STATE OF CALIFORNIA
Date: 2025‑09‑02
Case Number: B281051
Disposition: The appellate court modified the trial‑court judgment to (1) correct an arithmetic error in the attorney‑fee award, ordering Mark S. Zucker to pay Kim Zucker $870,000; (2) vacate the trial‑court’s March 14, 2014 order modifying temporary spousal support and remand for determination of pendente‑lite spousal support; and (3) affirm the trial‑court’s findings on the validity of the 1994 premarital agreement (PMA) and the award of spousal and child support, while denying all petitions for rehearing.

Holding

The court held that, for premarital agreements executed between 1986 and 2002, a trial court may rely on Family Code § 1612(a)(7) to shape public policy and may deem a spousal‑support limitation unenforceable solely because it is unconscionable at the time of enforcement, rather than being confined to the “unconscionable at execution” test of § 1615(a)(2). The court also corrected the attorney‑fee award arithmetic, ordered Mark to pay Kim $870,000, and remanded the pendente‑lite spousal‑support issue for further determination. All other trial‑court rulings were affirmed.

Narrative

Lead

In a sprawling, 57‑day, two‑phase dissolution proceeding that pitted a billionaire hedge‑fund founder against a former model with a history of mental‑health trauma, the California Court of Appeal clarified the reach of the Family Code’s public‑policy clause for premarital agreements and fixed a glaring arithmetic mistake that had inflated the award of attorney fees by more than $800,000. The decision, issued on September 2, 2025, underscores the appellate court’s willingness to look beyond the narrow “unconscionable at execution” standard and to enforce the broader policy‑shaping authority of § 1612(a)(7).

Procedural History

Kim and Mark S. Zucker married on February 6, 1994 after signing a 48‑page premarital agreement (PMA) that limited Kim’s community‑property rights and capped spousal support at $6,000 per month after a ten‑year marriage. The couple later had six children and separated in February 2011. Mark filed for dissolution on June 17, 2011. The Los Angeles Superior Court bifurcated the case: Phase I addressed the PMA’s validity; Phase II addressed child support, spousal support, and attorney‑fee awards. After a trial lasting 57 days, the trial court upheld the PMA’s community‑property provisions, found the spousal‑support limitation enforceable, and awarded Mark $5,283,346 in fees and costs, offset by a $4,764,258 payment, leaving a balance of $519,088. The court then ordered an additional contribution of $1,200,000, later corrected to $1,190,000, and ultimately entered a net fee award of $1,990,000—later reduced to $1,190,000 after a clerical error was discovered.

Both parties appealed and cross‑appealed. Kim challenged the trial court’s finding that the PMA was entered voluntarily and that the spousal‑support limitation was enforceable. Mark challenged the same limitation on the ground that it was unconscionable at enforcement, invoking the unsettled post‑2002 amendments to the Family Code. Both also contested the attorney‑fee award. The Court of Appeal consolidated the appeals (B281051, consolidated with B284981) and issued its opinion on March 3, 2022, which was subsequently modified by a certified order on April 1, 2022.

Factual Background

Mark Zucker, co‑founder and co‑CEO of Dorchester Capital Partners, entered the marriage with a net worth of roughly $10 million and annual earnings near $2 million. Kim Zucker, a former model and nutritionist, had a modest educational background, a history of anorexia, a traumatic hospitalization that included a knife‑point rape, and a prior short‑lived marriage that also involved a premarital agreement. In early 1994, while pregnant with her second child, Kim signed the PMA under pressure she later described as “the only way Mark would marry me.” The PMA was drafted by Mark’s attorney, Joseph Kibre, and reviewed—albeit briefly—by Kim’s counsel, Donna Beck Weaver, who sent Kim a detailed warning letter urging her not to sign.

The trial court’s fact‑finding record shows that Kim had independent counsel, received a full disclosure of assets, and signed the agreement after a series of discussions with Mark about his wealth and the need for a “tough” prenup. The court also noted that Kim’s own testimony indicated she understood the agreement’s effect and voluntarily chose marriage over single‑parenthood.

Issues Presented

  1. Validity of the PMA: Was the 1994 premarital agreement entered voluntarily, without duress, undue influence, or lack of capacity?
  2. Enforceability of the Spousal‑Support Limitation: Can a court deem a spousal‑support provision unenforceable solely because it is unconscionable at the time of enforcement, notwithstanding the pre‑2002 statutory framework?
  3. Attorney‑Fee Award: Did the trial court’s arithmetic error in calculating the fee award require correction, and what is the proper amount Mark must pay Kim?
  4. Temporary Spousal‑Support Modification: Was the trial court’s March 14, 2014 order modifying temporary spousal support proper, or should it be vacated and remanded?

Holdings and Reasoning

1. Validity of the PMA
The appellate court affirmed the trial court’s finding that Kim entered the PMA voluntarily. Applying the “substantial‑evidence” standard (In re Marriage of Hill & Dittmer, 202 Cal.App.4th at 1051) and the factors articulated in Bonds (24 Cal.4th at 31), the court concluded that the proximity of signing to the wedding, the presence of independent counsel, and the full financial disclosure negated any inference of duress or undue influence. The court gave weight to Weaver’s contemporaneous warning letter, which demonstrated that Kim was aware of the agreement’s harsh terms and chose to proceed regardless. The court also noted Kim’s prior experience with a premarital agreement in her earlier marriage, which undermined the claim of “lack of understanding.”

2. Enforceability of the Spousal‑Support Limitation
The most consequential holding concerns the scope of Family Code § 1612(a)(7). The court recognized that the statutory landscape is unsettled for agreements executed between 1986 (the adoption of the Uniform Premarital Agreement Act) and the 2002 amendment adding § 1612(c). Citing Pendleton (24 Cal.4th at 48‑49) and Facter (212 Cal.App.4th at 967), the court held that a trial court may invoke § 1612(a)(7) to shape public policy and may deem a spousal‑support limitation unenforceable solely because it is unconscionable at the time of enforcement, even if it was not unconscionable at execution. The court rejected Mark’s argument that the trial court was limited to the “unconscionable at execution” test of § 1615(a)(2). By doing so, the appellate court affirmed the trial court’s decision to enforce the spousal‑support limitation, finding that the parties had expressly contemplated future legislative changes and that the limitation was not “against public policy” under the broader policy‑shaping authority.

3. Attorney‑Fee Award
The appellate court identified a clear arithmetic error: the trial court’s net fee award of $1,990,000 was the product of a miscalculation (the correct net sum after the $10,000 reduction should have been $1,190,000). The court modified the judgment to order Mark to pay Kim $870,000—derived from the corrected balance after accounting for prior payments and the $10,000 reduction for “unreasonable fees.” This correction aligns the award with the fee‑order’s intent and eliminates the $800,000 overstatement.

4. Temporary Spousal‑Support Modification
The court vacated the trial court’s March 14, 2014 order that modified Kim’s temporary spousal support. The appellate panel found that the trial court failed to adequately consider the pendente‑lite support period beginning with Kim’s request for modification. Accordingly, the matter was remanded for the trial court to determine the appropriate amount of temporary spousal support from the date of Kim’s request forward.

All petitions for rehearing were denied, leaving the modified judgment in force.

Closing Analysis

The Zucker opinion is a landmark for family‑law practitioners handling premarital agreements executed before the 2002 statutory overhaul. By affirming the trial court’s ability to invoke § 1612(a)(7) to assess public policy at the time of enforcement, the Court of Appeal provides a roadmap for litigants seeking to invalidate spousal‑support waivers on the basis of contemporary inequities, even when the agreement passed the “voluntary” and “fair‑disclosure” tests at execution. This broader reading of § 1612 may encourage future courts to scrutinize legacy agreements more aggressively, especially where the economic disparity between spouses has widened dramatically.

The decision also serves as a cautionary tale about the importance of meticulous fee‑order calculations. The correction of a multi‑million‑dollar arithmetic error underscores the appellate court’s willingness to intervene when a trial court’s clerical mistake materially affects the parties’ financial obligations.

Unresolved issues remain. The appellate court left intact the trial court’s substantive spousal‑support award, but the remand on pendente‑lite support could produce a new determination that alters the overall support landscape. Moreover, while the court clarified the public‑policy authority of § 1612(a)(7), it did not definitively resolve whether a court must consider both execution‑time and enforcement‑time unconscionability, leaving room for divergent lower‑court applications.

For California family‑law attorneys, Zucker signals that premarital agreements—particularly those limiting spousal support—must be drafted with an eye toward future public‑policy shifts. Counsel should ensure that clients are fully apprised of the potential for later judicial scrutiny under § 1612(a)(7), and that fee‑order calculations are double‑checked before entry of judgment.
