Contract Interpretation
Contract interpretation is how courts figure out what the parties actually meant when they made their agreement. Because parties often disagree later about what their contract language means, courts have developed a set of rules and principles to resolve those disputes consistently.
Goal of Contract Interpretation
The central goal is to ascertain and give effect to the parties' intent at the time of contract formation. Courts want to know what the parties meant by their words when they made the deal, not what they wish the words meant after a dispute arises.
This follows the objective theory of contracts: courts look at the external manifestations of intent (the words on the page, the circumstances of the deal) rather than one party's secret, undisclosed intentions. If a reasonable person reading the contract would understand a term a certain way, that's typically the meaning the court will enforce.
When the language is disputed, courts apply various rules and principles of interpretation to resolve the ambiguity in a way that best reflects what the parties intended.

General vs. Specialized Interpretation Rules
General rules apply to all contracts regardless of type:
- The plain meaning rule requires giving words their ordinary, commonly accepted meaning.
- The context rule interprets language in light of the surrounding circumstances and the agreement as a whole.
- Contra proferentem construes ambiguous terms against the party who drafted the contract.
Specialized rules apply to particular types of contracts or provisions:
- These develop through case law or statutes for specific industries, such as insurance policies or collective bargaining agreements.
- They address unique features of certain contract types. For example, courts apply heightened scrutiny to exculpatory clauses and indemnification provisions because of the significant rights those clauses can waive.

Plain Meaning and Context Rules
These two rules represent competing approaches to interpretation, and jurisdictions differ on which one they favor.
The plain meaning rule applies when contract language is clear and unambiguous. Courts give the words their ordinary, plain meaning and will not look at outside (extrinsic) evidence to contradict or vary those terms. The idea is straightforward: if the language is clear on its face, there's nothing to interpret.
The context rule takes a broader view. Even if terms appear unambiguous at first glance, this approach allows courts to consider the entire contract document, the parties' relationship, the purpose of the agreement, and surrounding circumstances. Extrinsic evidence (like prior negotiations or industry custom) can come in to clarify meaning. The justification is that words don't have meaning in a vacuum; context shapes what parties actually understood.
The key tension: the plain meaning rule prioritizes textual certainty and predictability, while the context rule prioritizes accurately capturing what the parties actually intended.
Resolving Contract Ambiguities
An ambiguity exists when a contract term is reasonably susceptible to more than one interpretation. Courts distinguish between two types:
- Patent ambiguity is apparent on the face of the contract itself (e.g., a sentence that's grammatically unclear or contradictory provisions).
- Latent ambiguity only becomes apparent when you try to apply the contract to specific facts (e.g., a contract to sell "the property on Elm Street" when the seller owns two properties on Elm Street).
Once a court identifies an ambiguity, several interpretive tools come into play:
- Contra proferentem construes the ambiguous term against the drafter. This rule encourages clear, precise drafting and is especially important in adhesion contracts or situations with unequal bargaining power, where the non-drafting party had little ability to negotiate the language.
- Ejusdem generis applies when a contract lists specific items followed by a general catch-all term (like "and other similar items"). The general term is limited to things of the same kind or nature as the specific items listed. For example, a clause covering "cars, trucks, vans, and other vehicles" would likely include SUVs but probably not boats.
- Noscitur a sociis determines the meaning of an unclear word by looking at the words immediately surrounding it. A word takes color from its neighbors, so "trunk" means something different in a list about car parts than in a list about trees.
