We begin analyzing contract provisions with the presumption that a contract is the freely bargained agreement of the parties. Dexter Axle Co. v. Baan USA, Inc. , 833 N.E.2d 43, 49 (Ind. Ct. App. 2005). We recognize a very strong presumption that freely negotiated contracts are enforceable, based on the policy that it is in the best interest of the public for courts not to unnecessarily restrict the freedom to contract. Zollman v. Geneva Leasing Assocs., Inc. , 780 N.E.2d 387, 391–92 (Ind. Ct. App. 2002). When we review a contract, the intent of the parties is determined from the four corners of the instrument if the language is unambiguous.
