Uri, Inc. v. Kleberg Cnty.green2 sentences2025The parol-evidence rule “prohibits a party to an integrated written contract from presenting extrinsic evidence ‘for the purpose of creating an ambiguity or to give the contract a meaning different from that which its language imports.’” URI, Inc. v. Kleberg Cnty., 543 S.W.3d 755, 764 (Tex. 2018) (cleaned up). 2025To be sure, Lewis LLC has never claimed that it holds two notes, referring to the second note in its summary judgment motion as a “Corrected Promissory Note” that “amended” the original note to reflect that payments should be made to Lewis LLC instead of Lewis Inc. This characterization is consistent with both the inure-to-the-benefit provision of the settlement agreement and Thomas Koepke’s testimony that his then-attorney advised him to sign the second note “for the mediation, to get it all cleared up and settled.” See URI, Inc. v.

Santos v. Mid-Continent Refrigerator Companygreen2 sentences2022It is noteworthy that (1) one of the cases cited in Willacy for the proposition that “some basic contract principles apply” to a Section 1.111(e) agreement was Williams v. Glash, 789 S.W.2d 261, 264 (Tex. 1990), which was a mutual-mistake case; (2) Willacy expressly held that “a section 1.111(e) agreement may be rendered voidable if fraud is proven,” 555 S.W.3d at 34 ; and (3) cases relating to grounds for avoiding a contractual agreement have frequently used “fraud” and “mutual mistake” together in the same phrase, implying that the two doctrines are sufficiently related that they should be t 1983Appellants contend, therefore, that the parol evidence rule is not applicable as the basis to exclude the proffered testimony of fraud in the inducement for it is introduced not to vary the terms of the writing, “but to show that the writing itself from its inception, never became legally effective.” See Santos, 471 S.W.2d at 569 ; Guisinger v.
