CAITLIN CHALMERS, Case No. 25-cv-05083-JSC

Plaintiff, ORDER RE: DEFENDANT’S MOTION v. TO DISMISS AMENDED COMPLAINT

BRIAN CAYNE, Re: Dkt. No. 25 Defendant.

Plaintiff sues Defendant for damages arising after the dissolution of their romantic relationship. (Dkt. No. 21.)1 The Court previously granted Defendant’s motion for judgment on the pleadings and allowed Plaintiff leave to amend her complaint except as to her claim for imposition of a constructive trust. (Dkt. No. 20.) Now pending before the Court is Defendant’s motion to dismiss Plaintiff’s amended complaint. (Dkt. No. 25.) Having carefully considered the parties’ submissions, the Court concludes oral argument is not required, see N.D. Cal. Civ. L.R. 7- 1(b), and VACATES the January 29, 2026 hearing. The Court GRANTS Defendant’s motion to dismiss Plaintiff’s breach of contract, breach of implied contract, promissory estoppel, and negligent misrepresentation claims, but DENIES Defendant’s motion to dismiss Plaintiff’s intentional infliction of emotional distress claim. California Civil Code Section 43.5 bars Plaintiff’s breach of contract, breach of implied contract, and promissory estoppel claims, and Plaintiff does not oppose Defendant’s motion to dismiss her negligent misrepresentation claim. However, Plaintiff plausibly alleges the elements of an intentional infliction of emotional distress claim. Plaintiff, a Canadian citizen, and Defendant, a California resident, began a “romantic, intimate, and personal relationship” in fall 2021. (Dkt. No. 21 ¶¶ 3, 5, 6.) At that time, Plaintiff lived with her son in California and earned approximately $300,000 plus benefits annually in her job. (Id. ¶ 6.) “The parties developed a close bond and their love grew,” and Defendant asked Plaintiff to live with him, give up her job and her homes in California and Canada, and be a stay- at-home parent to her son and his son and “his life partner.” (Id. ¶ 8.) “He told her that [] in return, he would support her indefinitely and that she would be a co-owner of a home that he would purchase for the both of them.” (Id.) When Plaintiff “raised concern about where she would get spending money,” Defendant “promised her that he would make sure that she could use whatever funds she needed for anything she wanted.” (Id.) “[Plaintiff] was hesitant, but [Defendant] assured her that he loved her . . . and that she could trust him about the financial and cohabitating agreement he was offering.” (Id.) “Based upon his representations, [Plaintiff] accepted his terms.” (Id.) Plaintiff moved in with Defendant between January and March 2022. (Id. ¶ 9.) She sold her home in Canada, gave up her apartment in California, “got rid of most of her belongings,” and left her job. (Id.) When she “expressed her concern and hesitation” about giving up these things, Defendant “assured her that she did not have to worry, that he wanted to be in a committed relationship and that he had received a $27 million bonus and that she did not have to worry about finances.” (Id.) “Plaintiff did do all of the things he asked:” “cared for his son, cooked, fed, helped clothe[], helped him with school projects, played and entertained him, arranged medical appointments, social calendars and shuttled [him] to and from extracurriculars and appointments;” “cared for the home in the particular ways [Defendant] desired;” “ran errands for [Defendant] and his son;” and “helped [Defendant] with property searches for the real estate that he wanted to purchase.” (Id.) Defendant “referred to [Plaintiff] and her son as his wife and son in official correspondence,” including in a letter related to the potential purchase of a home in Carmel. (Id.) continuously, without ever leaving each other.” (Id. ¶ 10.) Their relationship was “stable, as the parties lived together as committed partners,” and they “planned their futures together, and executed those plans towards their common goal of a shared life together.” (Id.) “During their relationship, [Defendant] did not want the parties to be separated.” (Id. ¶ 11.) Defendant “did not want [Plaintiff] to leave the home without informing him where she was going,” convinced her to change oncologists while undergoing cancer treatment, disrupted her sleep, and searched her phone. (Id.) “He told her that he loved her, that he needed her and that he wanted to be sure she was safe.” (Id.) While on vacation, Defendant decided they should purchase a home in Canada and live there. (Id. ¶ 12.) After making a down payment on a home in Canada, Defendant “sent Plaintiff and her son” there and “then informed Plaintiff that he was breaking off the relationship.” (Id.) “Plaintiff and her son were stranded without any way to return to California, with no job, no home, no car, [and] no childcare.” (Id.) Plaintiff sued Defendant in state court asserting claims for breach of oral contracts for property and support, breach of implied contract, dissolution of partnership and community assets, breach of fiduciary duty, fraud, promissory estoppel, negligent misrepresentation, intentional infliction of emotional distress, conversion, and imposition of constructive trust. (Dkt. No. 1-1 at 9-29.) Defendant removed the case to this Court based on diversity jurisdiction and answered the complaint. (Dkt. Nos. 1, 3.)2 He then moved for judgment on the pleadings. (Dkt. No. 10.) The Court granted Defendant’s motion for judgment on the pleadings. (Dkt. No. 20.) The Court held California Civil Code Sections 43.4 and 43.5, which prohibit causes of action arising from a breach of a promise or fraudulent promise to marry, barred Plaintiff’s claims for breach of contract, breach of implied contract, fraud, promissory estoppel, and negligent misrepresentation. (Id. at 3-6.) Plaintiff also failed to allege a sufficiently stable and significant relationship to state
