How to Interpret Ambiguous Terms in Commercial Contracts

Commercial contracts often include terms that may not be as clear as they should be. Ambiguity can arise from vague language, missing definitions, or wording that doesn’t reflect what the parties actually meant. When a term is unclear, the parties may disagree on certain obligations, deadlines, or payment requirements. Understanding how ambiguous terms are interpreted can protect your business and reduce the risk of costly disputes.

At Oberle Law, PLLC, based in Bohemia, New York, I help clients nationwide review contract language, identify ambiguous clauses, and resolve disputes before they escalate. If you’re facing uncertainty about commercial contract stipulations, reach out to discuss your options and next steps.

How Courts Treat Ambiguous Contract Language

When a court reviews ambiguous commercial contract stipulations, the first question is whether the language is genuinely unclear. Courts generally try to interpret the contract based on what the parties intended at the time they signed it. If the wording is vague, judges will look for outside evidence, such as prior drafts, emails, or industry practice, to determine the most reasonable meaning.

If a term can be reasonably interpreted in more than one way, the court may rely on specific rules that are designed to limit unfair outcomes. One common rule is that ambiguous terms are interpreted against the party that drafted the contract. This means a business that prepared the agreement may be held to a stricter standard if the wording favors them in a dispute.

A contract may also be considered ambiguous when it contains conflicting provisions. For example, if one section requires delivery within 30 days but another section states delivery will occur “as soon as possible,” a court may find the term unclear and examine other evidence to determine what was intended.

Common Types of Ambiguous Terms

Ambiguous terms in commercial contracts often arise for specific reasons. Knowing these types can help you avoid unclear language when negotiating or drafting agreements, and it can also help when you’re working with an experienced business lawyer to review your documents. The primary types of ambiguous terms in business contracts include:

  • Undefined terms: When specific terms or keywords aren’t defined, they could be interpreted differently by different parties.

  • Vague time frames: Phrases such as “promptly,” “as soon as possible,” or “reasonable time” can create disputes if there’s no agreed standard.

  • Incomplete provisions: When a clause doesn’t fully explain the obligations, both parties could disagree on what’s required.

  • Overlapping clauses: When two sections address the same topic but state different points, the contract may be deemed inconsistent.

These issues often arise in commercial contract provisions governing payment, delivery, performance standards, and termination rights. If you are facing issues with an ambiguous commercial contract, reach out to an attorney for tailored guidance and advice.

How to Interpret Ambiguous Terms Before a Dispute

When you notice unclear language, it's important to take immediate steps to prevent a dispute from developing. Carefully reviewing the document can help you interpret the contract to align with your business goals and protect your interests.

First, identify the specific clause that is unclear and compare it to the rest of the agreement. If the ambiguous term conflicts with other provisions, the contract may need clarification. In many cases, simply confirming the intent in writing can prevent future problems.

Next, look at how the term is used in practice. If both parties have already acted in a way that reflects a certain interpretation, that conduct can support a reasonable meaning. This can be especially helpful when commercial contract stipulations were vague from the start, but the parties developed an operational understanding over time.

Finally, consider adding definitions or clarifying language through an amendment or written addendum. This can help avoid disputes and make the contract easier to enforce.

How Courts Resolve Ambiguity During Disputes

If a dispute over the terms in a commercial contract goes to court, the judge will apply established rules to interpret the language. Courts often start by examining the plain meaning of the vague terminology and then consider the contract as a whole. If the contract still remains unclear, the courts may use external evidence to determine the parties’ intent. This can include:

  • Prior drafts: Changes between versions can reveal the parties' intent.

  • Negotiation history: Emails or other communications may indicate how the terms were discussed.

  • Industry practice: Common usage in the relevant industry can guide interpretation.

  • Course of performance: How the parties acted under the contract can show what they believed the terms meant.

U.S. courts may also apply specific interpretive rules. One common rule is that ambiguities are interpreted against the drafter. Another rule is that contracts should be read to give effect to every clause, rather than leaving sections meaningless.

Practical Steps to Protect Your Business

You don’t have to wait for a dispute to arise to address unclear contract language. Taking proactive steps can reduce risk and help your business stay focused on operations instead of litigation. If you've discovered vague or unclear terms in a business contract, consider taking the following actions:

  • Review contract language early: Identify ambiguous terms before signing and ask for clarification.

  • Add clear definitions: Define the key terms and include examples where needed.

  • Align internal expectations: Make sure your firm understands how the contract terms apply in day-to-day practice.

  • Document intent: Keep records of any discussions and agreements that can support your interpretation if a dispute arises.

  • Use amendments when needed: If business conditions change, update the contract to reflect the new reality and working conditions.

These steps can strengthen your position if commercial contract terms are later challenged. For experienced guidance and legal advice, consult a skilled business attorney.
