In Band v. Libby (2D11-4942), the Second District held (in addition to addressing other issues) that a claim for breach of fiduciary duty can be waived. The court stated:
We hold that a party may waive a claim based on the breach of a fiduciary duty. "Parties, by their own knowledge and conduct, can waive or be estopped to raise a wide array of constitutional, statutory, and common law rights . . . ." Ruggio v. Vining, 755 So. 2d 792, 795 (Fla. 2d DCA 2000). Indeed, "[a] party may waive any rights to which he or she is legally entitled, by actions or conduct warranting an inference that a known right has been relinquished." Torres v. K-Site 500 Assocs., 632 So. 2d 110, 112 (Fla. 3d DCA 1994) (emphasis added). It follows that a claim based on a breach of fiduciary duty, like any other claim, may be waived.
