Opinion

San Francisco Division MACKENZIE FOTSCH, Case No. 26-cv-04505-LB

Plaintiff, ORDER GRANTING IN PART MOTION TO STRIKE v. Re: ECF No. 17 Defendant. This is a dispute between plaintiff Mackenzie Fotsch and defendant Matthew Shroder, who were in a romantic relationship until they broke up in November 2025. In February 2025, before their relationship ended, Shroder bought a house in Sausalito for $2.2M, which is titled only in his name. Fotsch alleges that that the parties orally agreed to pool their resources and share ownership of the house: seventy-five percent to Shroder (who funded the all-cash purchase) and twenty-five percent to Fotsch, to be earned through payments towards improvements and property taxes and through her services managing the property. The parties lived together at the house (though Shroder maintained his residence in Nevada). They worked with counsel to memorialize their oral agreement, but when their relationship ended, Shroder moved out, Fotsch stayed, and the parties’ negotiations broke down. Shroder sued Fotsch in Marin County Superior Court in March 2026 for unlawful detainer. claims.1 Shroder removed the case to federal court, asserting diversity jurisdiction.2 He then moved under California’s Strategic Lawsuits Against Public Participation (SLAPP) law, Cal. Civ. Proc. Code § 425.16, to strike six claims in the complaint: (1) breach of pooling agreement (claim one); (2) breach of express oral contract (claim two), (3) breach of implied contract (claim three); (4) unjust enrichment (claim six); (5) breach of fiduciary duty (claim seven), and (6) conversion (claim eleven). For all claims but claim six for unjust enrichment, he asserts that the claims are predicated on the unlawful-detainer action and barred by California Civil Code § 47(b)’s absolute litigation privilege. He contends that claim six for unjust enrichment fails because California does not recognize unjust enrichment as a standalone claim.3 The motion is granted in part. The complaint pleads the filing and service of the unlawful- detainer action as conduct that breached the parties’ agreements, breached Shroder’s fiduciary duties, and converted Fotsch’s property. These discrete allegations arise from protected activity, and the litigation privilege bars them as a matter of law. The court strikes them from claims one, two, three, seven, and eleven without leave to amend because the privilege is absolute and repleading them would be futile. The claims are also predicated on conduct that is not protected petitioning: the alleged pre-suit repudiation of the parties’ agreements, the refusal to recognize Fotsch’s claimed ownership interest, her exclusion from the property’s ownership and management, and the refusal to account for her share. The motion does not address the sufficiency of these grounds to support the claims, which remain in the case and are unaffected by this order. The complaint’s references to the unlawful-detainer action may remain as background and evidence, just not as a basis for liability. 1 Compl. – ECF No. 1 at 8–17 (¶¶ 7–8, 10–19, 21, 23–29, 33–34). Citations refer to material in the Electronic Case File (ECF); pinpoint citations are to the ECF-generated page numbers at the top of documents. 2 Notice of Removal – ECF No. 1 at 1–3. The motion to dismiss claim six for unjust enrichment is denied. Shroder identifies no protected activity under SLAPP, and the claim otherwise is cognizable as a quasi-contract claim seeking restitution. 1. The Relationship, the Property, and the Agreement The parties began dating in October 2018, and the relationship became serious. In 2022, Shroder relocated to Incline Village, Nevada, but stayed at Fotsch’s San Francisco residence nearly half the year. From 2022 to early 2025, the parties cohabited at each other’s residences and pooled and shared living expenses. In 2025, they discussed marriage and starting a family, and they decided to buy a home together.4 Fotsch alleges a “pooling agreement,” whereby the parties would live together in the house, Shroder would fund the purchase price and hold a seventy-five-percent ownership interest, and Fotsch would have a twenty-five percent ownership interest by “contributing 25% of the initial purchase price . . . through payment of capital improvements and payment of real-property taxes after the purchase of the property.” Improvements and repairs beyond Fotsch’s “initial buy in” would be split on a pro rata basis based on their respective ownership interests. They would split costs for utilities and household supplies. Fotsch would manage the property and its improvements due to Shroder’s frequent travel. Profits and losses (including rents, income, and gains/losses) would be split pro rata based on their ownership shares.5 The parties bought the house at 83 Princess Street in Sausalito, California, on February 21, 2025, for $2,217,827.88 in an all-cash purchase. The deed was recorded solely in Shroder’s name.6 Fotsch alleges that the rapid closing left no time to form the jointly owned entity that was to take title, her funds were tied up in stock that could not be liquidated, and the parties agreed to transfer title to a joint entity later.7 The parties moved into the property together. Fotsch served as project manager/developer for the property, managed an SB 330 development application 4 Compl. – ECF No. 1 at 8–10 (¶¶ 7–13). 5 Id. at 10–11 (¶ 14), 14 (¶ 26), 18–19 (¶ 38), 21 (¶ 48). 6 Id. (¶¶ 14–15). (submitted in May 2025 in Shroder’s name after advice that a title transfer might jeopardize it), and contributed $142,555.23 to her twenty-five percent buy-in of $554,456.97 (tracked in a shared spreadsheet).8 In 2025, the parties worked with counsel to form the corporate entity, as they agreed in February 2025.9 For example, on March 21, 2025, their counsel circulated a draft co- ownership agreement that reflected Fotsch’s twenty-five percent interest.10 2. The Breach and the Lawsuits Shroder ended the relationship on November 6, 2025, and moved out of the Sausalito house. Fotsch remained at the property and transferred the utilities to her name.11 The parties continued their negotiations to document their agreement, but on January 20, 2026, Shroder repudiated the agreement by proposing new terms that were more favorable to him.12 In February 2026, Shroder offered to buy out Fotsch’s interest. She declined. On February 24, 2026, through counsel, Shroder told Fotsch that her license to remain at the house was terminated and demanded that she vacate the property. On March 2, 2026, he filed an unlawful-detainer action in Marin Superior Court, serving Fotsch on March 13. The unlawful-detainer action remains pending, and Fotsch moved to stay it in favor of this action, which she filed on March 23, 2026, also in Marin County.13 The complaint in the federal case has fourteen claims. The claims relevant to the motion are as follows: (1) breach of the pooling agreement to treat the property as joint property, subject to the seventy-five/twenty-five ownership split, under Marvin v. Marvin (claim one); (2) breach of the parties’ express oral contract based on that agreement (claim two); (3) breach of implied contract
