less it was explicit and conspicuous.
[3][4][5][6][7] Whether a contract is ambiguous as written is a question of law which we review de novo. United
States v. Brekke, 97 F.3d 1043, 1049 (8th Cir.1996). Missouri law accords the terms of an insurance policy “the
meaning which would be attached by an ordinary person of average understanding.” Seeck v. Geico General Ins.
Co., 212 S.W.3d 129, 132 (Mo.2007). If the language of the contract is clear and unambiguous, it must be enforced
as written. Krombach v. Mayflower Ins. Co., Ltd., 827 S.W.2d 208, 210 (Mo.1992). If the policy contains ambigui-
ties, however, we must resolve them “in favor of the insured.” Seeck, 212 S.W.3d at 132. “An ambiguity exists when
there is duplicity, indistinctness, or uncertainty in the meaning of the language in the policy.” Id.

There are a number of Missouri cases in which general cooperation clauses like the one at issue here have been in-
terpreted to require the insured to perform acts not explicitly stated in the insurance policy. See, e.g., Smith v. Pro-
gressive Cas. Ins. Co., 61 S.W.3d 280, 283 (Mo.Ct.App.2001); Hayes v. United Fire & Cas. Co., 3 S.W.3d 853,
857-59 (Mo.Ct.App.1999); Riffe v. Peeler, 684 S.W.2d 539, 542-43 (Mo.Ct.App.1984); Meyers, 375 S.W.2d at 15.
In Riffe, the insured breached a general cooperation clause by failing to assist in the preparation of interrogatories

provide relevant documents, answer interrogatories, submit to depositions, and testify at trial if necessary.
The cases relied upon by the Johnstons are not to the contrary. American Home Assurance Company v. Pope, 08–
2848, 591 F.3d 992, 999 (8th Cir.2010) involved an insurance policy containing contradictory provisions. There, the
The Johnstons assert that the policy’s cooperation clause should be deemed unenforceable even if unambiguous be-
cause it amounts to a waiver of constitutional rights. They rely primarily on Malan Realty Investors, Inc. v. Harris,
953 S.W.2d 624, 627 (Mo.1997), in which the Missouri Supreme Court stated that “[t]o effectively waive a jury trial
by contract, clear, unambiguous, unmistakable, and conspicuous language is required.” Malan is inapposite, howev-
er, because the MPC insurance policy did not require an actual waiver of Dr. Bubenik’s constitutional rights. He
