Facts

Plaintiff, through his agent, and defendant executed a written agreement stating that plaintiff sold defendant all logs marked "H. C. A.," cut in the winters of 1882 and 1883, at ten dollars per thousand feet, boom scale at Minneapolis, with cash payment as scale bills were produced. In plaintiff's action for the purchase money, defendant pleaded that plaintiff had orally warranted the quality of the logs at the time of sale and that the warranty was breached. Defendant offered oral testimony to prove that warranty, and the trial court admitted it over plaintiff's objection. No claim for reformation was made, and any charge of fraud in making the sale was expressly disclaimed at trial.

Issue

When parties execute a written contract for the sale of personal property that on its face appears to be a complete expression of their agreement, may a party introduce parol evidence of a contemporaneous oral warranty of quality? More specifically, is such a warranty a collateral agreement or a term of the sale contract itself?

Rule

The completeness of a written contract is determined from the writing itself. If the writing on its face imports a complete legal obligation and does not appear to be an informal or incomplete memorandum, the law conclusively presumes that the parties reduced their entire agreement to writing, and parol evidence may not be admitted to add a term even where the writing is silent on that point. In a sale of personal property, a warranty of quality is a term of the contract of sale, not a distinct collateral agreement, and therefore cannot be added by contemporaneous oral testimony to an integrated written contract.

One of 10 multiple-choice questions for this case. Pick an answer to see why.
In Duluth, Nora Kim signed a document with Owen Pike stating: "I have this day sold to Owen Pike my 40 industrial pumps stored in Duluth for $48,000, payment due within 20 days." Both signed it. After delivery, Owen refuses to pay in full and offers testimony that Nora orally promised at signing that every pump would operate continuously for 12 hours without overheating.

Should the court admit Owen's testimony about the oral promise?

Explanation. The majority rule is that completeness is determined from the writing itself. If the writing on its face imports a complete legal obligation, it is conclusively presumed to contain the whole agreement, and parol evidence may not add a term even on a subject the writing does not mention. In a sale of personal property, a warranty of quality or performance is part of the sale contract, not a separate collateral agreement. (Derived from Thompson v. Libby (n.d.).)
