No, the relationship is still contractual in nature. It does not rise to the level of a fiduciary duty.
In order to sue for breach of fiduciary duty, a plaintiff must first allege the existence of a fiduciary relationship. "It is not always a simple matter to determine whether a fiduciary relationship exists. [Keenan v. D.H. Blair & Co. (S.D.N.Y.1993) 838 F.Supp. 82, 89 ([t]he precise contours of a fiduciary relationship are incapable of expression); Franklin Supply Co. v. Tolman (9th Cir.1972) 454 F.2d 1059, 1065 ([a] 'fiduciary relation' is an elusive status ...)." Fleet Nat. Bank v. H & D Entertainment, Inc. (D.Mass.,1996) 926 F.Supp. 226, 242 -243 (discussing whether and when fiduciary relationship arises in accountant-client context) (certain quotations omitted).]
For example, the relationship between an accountant providing independent audit services and its client does not give rise to a fiduciary obligation. [Franklin Supply, supra, at 1065; Mishkin v. Peat, Marwick, Mitchell & Co. (S.D.N.Y. 1990) 744 F.Supp. 531, 552.] However, a fiduciary relationship may exist where the accountant performs more than merely basic accounting functions. [See, e.g., Myers v. Finkle (4th Cir.1991) 950 F.2d 165, 168 (where accountant gave investment advice, a fiduciary relationship was created with respect to all services rendered by that accountant); Allard v. Smith et al. (Bankr. E.D.Mich.1986) 56 B.R. 936 (where performing audits, the court found that accountant's client reposited "faith, confidence, trust and reliance ... upon the judgment and advice" of the accountant such that a fiduciary relationship arose). ]
The California Court of Appeal case of Oakland Raiders v. National Football League (2005) 131 Cal.App.4th 621, 633 cites examples of circumstances under which the courts have not found fiduciary relationship and notes that "California courts have rejected attempts to extend fiduciary obligations to relationships where the imposition of such an affirmative duty is unwarranted".
