Wife of late Padres owner Peter Seidler sues for control of team

Sheel Seidler, the widow of San Diego Padres chairman Peter Seidler, has filed a lawsuit against her late husband’s brothers, Robert and Matthew Seidler, accusing them of fiduciary breaches and self-dealing as executors of Peter’s estate. She claims they ostracized her and her three children from the organization after Peter’s death in November 2023. Sheel opposes the Padres’ decision to appoint Peter’s older brother, John Seidler, as the team’s control person, asserting it contradicts Peter’s wishes and her own role as the largest individual stakeholder. In her lawsuit, Sheel seeks to be named control person, citing her position as the sole beneficiary of the Seidler Trusts, which own a significant share of the franchise.

The Seidler Trust refutes Sheel’s claims, arguing that Peter’s estate plan explicitly excluded her from serving as trustee or control person, a stance she allegedly agreed to in a sworn 2020 document. The trust also notes Sheel’s past support for John Seidler’s leadership. Despite this, Sheel’s complaint accuses Robert and Matthew of misleading her, mismanaging trust assets, and undermining Peter’s legacy. Sheel alleges they used trust funds to intimidate her and excluded her from the team’s operations and legacy events. She further claims that a handwritten note from Peter prioritized her and their children as successors, a document she contends has been ignored.

Under Peter’s leadership, the Padres grew into a financial powerhouse, achieving competitive success and fan engagement. Sheel argues she is best positioned to carry forward Peter’s vision, emphasizing her dedication to the team’s future and her children’s eventual inheritance. She believes her exclusion jeopardizes the family’s legacy and aims to honor Peter’s dream of bringing championships to San Diego. Meanwhile, John Seidler’s appointment as control person is pending MLB owners’ approval, which could occur at their February meeting.
