Under general Alabama rules of contract interpretation, the intent of the contracting parties is discerned from the whole of the contract. See Loerch v. National Bank of Commerce of Birmingham, 624 So. 2d 552, 553 (Ala. 1993). Where there is no indication that the terms of the contract are used in a special or technical sense, they will be given their ordinary, plain, and natural meaning. See Ex parte Dan Tucker Auto Sales, Inc., 718 So. 2d 33, 36 (Ala. 1998). If the court determines that the terms are unambiguous (susceptible of only one reasonable meaning), then the court will presume that the parties intended what they stated and will enforce the contract as written. See id. at 36; Voyager Life Ins. Co. v. Whitson, 703 So. 2d 944, 948 (Ala. 1997). On the other hand, if the court determines that the terms are ambiguous (susceptible of more than one reasonable meaning), then the court must use established rules of contract construction to resolve the ambiguity. See Whitson, 703 So. 2d at 948. Under those established rules of contract construction, where there is a choice between a valid construction and an invalid construction the court has a duty to accept the construction that will uphold, rather than destroy, the contract and that will give effect and meaning to all of its terms. See id. at 948-49; Sullivan, Long & Hagerty v. Southern Elec. Generating Co., 667 So. 2d 722, 725 (Ala. 1995). Additionally, "if there exists inconsistency between two clauses of a contract which cannot be reconciled, the inconsistency must be resolved in favor of the prior clause, unless an intention to thereafter qualify is plainly expressed." City of Fairhope v. Town of Daphne, 282 Ala. 51, 58, 208 So. 2d 917, 924 (1968); see Whitson, 703 So. 2d at 949. Last, if all other rules of contract construction fail to resolve the ambiguity, then, under the rule of contra proferentem, any ambiguity must be construed against the drafter of the contract. See Lackey v. Central Bank of the South, 710 So. 2d 419, 422 (Ala. 1998).
