California First-Year Law Students' Exam (Baby Bar) — MCContractsMedium
A buyer and a seller enter into a written contract for the sale of a commercial property. The contract includes the following clause: 'This written instrument constitutes the entire agreement between the parties and supersedes all prior discussions, negotiations, and agreements, whether oral or written.' During negotiations, the seller orally promised to install a new HVAC system before closing. This promise was not included in the final written contract. If the buyer attempts to introduce evidence of this oral promise in court, what is the most likely outcome?
- AThe court will allow the evidence because it concerns a separate, collateral agreement.
- BThe court will exclude the evidence due to the parol evidence rule and the integration clause.
- CThe court will allow the evidence under the parol evidence rule as it adds to, but does not contradict, the written contract.
- DThe court will allow the evidence to show a condition precedent to the contract's formation.
Show answer & explanationAnswer & explanation
Correct answer: B. The court will exclude the evidence due to the parol evidence rule and the integration clause.
The parol evidence rule generally prevents the introduction of extrinsic evidence (oral or written) to contradict, vary, or add to the terms of a fully integrated written contract. An integration clause like the one described signifies that the written contract is the complete and final agreement, making the oral promise inadmissible.
Why the other options are wrong
- A. A new HVAC system would likely be considered within the scope of a commercial property sale, not a collateral agreement.
- C. The integration clause indicates the contract is fully integrated, meaning no additional terms can be added.
- D. Installing an HVAC system is not a condition precedent to the formation of the contract but rather a term of performance.
Parol Evidence Rule
A common law rule that prevents the introduction of extrinsic evidence (oral or written) to contradict, vary, or add to the terms of a fully integrated written contract.
- Applies to prior or contemporaneous agreements.
- Does not apply to subsequent modifications.
- Exceptions exist (e.g., to explain ambiguity, show fraud, or prove conditions precedent).
Memory trick: Parol Evidence Bars Prior Promises from Entering Final Paper.
