Court Classifies Writing as Partial
Priscilla Parks and Premier Manufacturing signed a purchase order listing price and quantity for custom parts but omitting delivery dates and specifications for color and finish. In later litigation over those omitted details, the court first examined the writing under the governing standard to decide whether it was completely or partially integrated. Finding the order silent on key performance terms, the court ruled it partially integrated and allowed evidence of the parties' prior discussions on those points.
Consistent Term Admitted to Supplement
Perry Pratt and Precision Tools executed a written supply contract covering base pricing and quality benchmarks but silent on advance tooling funds triggered by new regulations. Pratt later sought to prove an oral understanding reached during negotiations that Precision would provide such funds if federal standards changed. Because the writing addressed only pricing and quality, the court treated it as partially integrated and admitted the consistent oral term.

Distinguishing Partial from Complete
Pierce Patterson and Prism Analytics signed a five-page services agreement detailing compensation and billable-hour minimums together with a merger clause, yet the document said nothing about outside mediation work discussed orally during talks. The court applied the preliminary test to classify the writing and concluded it was only partially integrated because the parties had not adopted it as a complete and exclusive statement. Evidence of the oral understanding was therefore admissible.
Preliminary Determination Controls
Patricia Patel and Prime Logistics entered a thirty-page blade-supply contract covering dimensions, pricing, and warranties but silent on a promised local warehouse for spare parts. Before addressing any parol-evidence question, the court decided as a threshold matter whether the writing was completely or partially integrated. Finding the document not adopted as a complete statement, the court ruled it partially integrated and permitted evidence of the warehouse term.
Common questions
Frequently Asked
4
How does a court decide whether a writing is partially integrated?+
The court makes this determination as a preliminary question before interpreting the contract or applying the parol evidence rule. It examines the writing's completeness, any merger clause, and surrounding circumstances to decide whether the parties adopted the document as a complete and exclusive statement.
Supporting sources
What evidence may be admitted when a writing is only partially integrated?+
Evidence of consistent additional terms is admissible to supplement the writing. Evidence that would contradict an integrated term remains inadmissible.
Supporting sources
Does a merger clause automatically make an agreement completely integrated?+
A merger clause is strong evidence of complete integration but is not conclusive. The court still examines the writing's scope and the parties' negotiations to decide whether the document was intended as the complete and exclusive statement of all terms.
Supporting sources
What is the difference between a partial integration and a complete integration?+
A completely integrated agreement is adopted by the parties as a complete and exclusive statement of all terms. A partially integrated agreement is an integrated agreement that falls short of that standard, allowing consistent additional terms to be proved by extrinsic evidence.
