Merger Clause Bars Post-Closing Claim
Iain Irons contracted to buy a warehouse from Inertia Dynamics. The purchase agreement contained a merger clause declaring the writing the complete agreement. After closing the deed omitted any reference to an earlier promise to repair the roof. Iain later discovered water damage and sued to enforce the repair promise. The court refused to consider the prior promise because the integrated writing and deed controlled the parties' obligations.
Term Sheet Incorporated by Reference
Ira Irving negotiated a loan with Ideal Solutions. An initial term sheet described an interest-rate cap but stated it was for discussion only. The final signed loan agreement expressly stated it was based on the attached term sheet. When Ideal Solutions later charged a higher rate, Ira sued. The court treated the term sheet's cap as part of the integrated contract because the final writing adopted its terms.

Trade Usage Supplements Quantity Term
Imani Idowu bought asphalt from Integrity Partners under a long-term supply contract that fixed a stated quantity. The contract was lengthy and contained detailed terms. Imani proved that trade usage and prior dealings treated such quantity figures as adjustable projections rather than strict limits. The court allowed the evidence to explain the integrated contract because the usage was consistent with the written quantity term.

Common questions
Frequently Asked
4
How does a court decide whether a writing is an integrated contract?+
A court examines whether the writing appears complete and specific on its face and whether the parties manifested an intent that it serve as the final expression of their agreement. An explicit integration clause is strong but not conclusive evidence of that intent.
Supporting sources
What effect does an integrated contract have on prior oral promises?+
A completely integrated contract discharges prior agreements that fall within its scope or contradict its terms. Evidence of those prior agreements is inadmissible to vary or add to the writing.
Supporting sources
Can a preliminary document become part of an integrated contract?+
Yes. Even if a communication is not itself an offer, its promises or representations may be incorporated into a later writing that the parties adopt as their final agreement.
Supporting sources
Does a merger clause in a real-estate contract prevent enforcement of promises omitted from the deed?+
Yes. After the buyer accepts the deed, merger and the parol-evidence rule ordinarily bar enforcement of prior promises not reflected in the deed, subject to limited exceptions such as fraud or collateral agreements.
