Does an integration clause shut out side agreements in Utah?
Oral side agreements, yes: in the face of a clear integration clause, extrinsic evidence of a separate oral agreement is not admissible on the question of integration (Tangren Family Trust v. Tangren). Extrinsic evidence is still considered, even against a clear integration clause, where the contract is alleged to be a forgery, a joke, a sham, lacking in consideration, or voidable for fraud, duress, mistake or illegality (Tangren), and an integration clause does not bar extrinsic evidence where the language of the agreement is ambiguous (Watkins v. Ford), a question on which any relevant evidence must be considered and the writing read in light of the surrounding circumstances. Tangren overruled prior Utah cases to the extent they allowed extrinsic evidence of a separate oral agreement against a clear integration clause, and affirmed the exclusion of that evidence. Written instruments are different: where two or more parties sign contemporaneous, executed instruments related to the same transaction, those agreements are construed together even where one contains a clear integration clause (Montes v. National Buick GMC, 2024).
The trap
An integration clause does not by itself knock out a separately signed same-day writing: in Montes (a car purchase agreement with an integration clause and a separately signed arbitration agreement) the court read Tangren's holding as limited to oral side agreements and required the two instruments to be construed together. Drafters who want a same-day document excluded cannot rely on the merger clause alone.

The words that state the rule
We hold today that in the face of a clear integration clause, extrinsic evidence of a separate oral agreement is not admissible on the question of integration.
The words that state the rule
Where a contract by an explicit term purports to be integrated, we will nevertheless allow extrinsic evidence in support of an argument that the contract is not, in fact, valid for certain reasons that we have specified. We have held that extrinsic evi *331 dence is appropriately considered, even in the face of a clear integration clause, where the contract is alleged to be a forgery, a joke, a sham, lacking in consideration, or where a contract is voidable for fraud, duress, mistake, or illegality.
The words that state the rule
While we agree that the Contracts contain integration clauses,1 the integration clauses do not necessarily bar the introduction of extrinsic evidence. Tangren Family Trust v. Tangren, 2008 UT 20, ¶ 11, 182 P.3d 326. Despite a finding that an “agreement is integrated, . . . parol evidence may be admitted . . . if . . . the language of the agreement is ambiguous.
The words that state the rule
Where two or more parties sign contemporaneous, executed instruments related to the same transaction, those agreements should be construed together—even where one contains a clear integration clause.
The words that state the rule
Tangren was careful to specify that its holding applied only to oral side agreements like the one at issue there. See Tangren, 2008 UT 20, ¶¶ 1, 17, 19. And, while Tangren indeed overruled or limited many prior cases, it specified that it did so only “[t]o the extent” that those cases “suggest[ed] that extrinsic evidence of a separate oral agreement [was] admissible where the contract contains a clear integration clause.”
The words that state the rule
He and the dealership, National Buick GMC (National), signed at least two agreements in connection with the sale: a Purchase Agreement and an Arbitration Agreement.
The words that state the rule
We reverse the determination that the Purchase Agreement’s integration clause precludes consideration of the Arbitration Agreement, vacate the ruling denying the motion to arbitrate, and remand for further proceedings consistent with this opinion.
The words that state the rule
To argue that the Lease is not the complete agreement of the parties is to argue in direct contradiction to the clear integration clause. Thus, we will not allow extrinsic evidence of a separate agreement to be considered on the question of integration in the face of a clear integration clause. 19 To the extent any of our prior cases provide otherwise, we overrule those cases.
The words that state the rule
Extrinsic evidence of a separate oral agreement is not admissible on the question of integration where the contract at issue contains a clear integration clause. Thus, evidence that Richard and Rodney entered into a separate oral agreement that the Lease is invalid or that its effectiveness is subject to a condition precedent was improperly considered by the trial court, given that the Lease contains a clear integration clause. We conclude that the Lease is integrated and that its terms are unambiguous. Thus, the parol evidence rule bars the admission of all extrinsic evidence regarding the Lease. Affirmed.
The words that state the rule
“When determining whether a contract is ambiguous, any relevant evidence must be considered” and “the better-reasoned approach is to consider the writing in light of the surrounding circumstances.” Ward v. Intermountain Farmers Ass’n, 907 P.2d 264, 268 (Utah 1995).
