When business owners think about contract disputes, they often imagine something dramatic, a major breach, a missed payment, a deal gone completely off the rails. In reality, some of the most expensive lawsuits do not come from bold, intentional wrongdoing. They come from something far more mundane: unclear contract language.
At our law firm, we litigate contracts every day, and we can tell you with complete certainty that many disputes could have been avoided with clearer wording, defined responsibilities, and tighter drafting. Understanding how ambiguous terms create costly litigation is one of the smartest business moves you can make.
Below, we break down the most common contract pitfalls and how to avoid them.
What Counts As an “Ambiguous” Contract Term?
In simple terms, a contract provision is ambiguous when reasonable people can interpret it in more than one way. When that happens, neither side is truly at fault for the disagreement. Instead, the contract itself becomes the problem.
Courts often must intervene, and once they do, you lose control of the outcome.
Ambiguity usually appears when:
- A term is vague, such as requiring payment in a “reasonable time.”
- A clause is missing detail, such as who is responsible for a specific task.
- Two sections of the contract contradict each other.
- A term has industry-specific meaning, but the contract does not define it.
These issues might seem small, but in business transactions, where timelines, costs, and obligations stack quickly, small drafting flaws often escalate into six- or seven-figure fights.
Common Ambiguous Phrases That Trigger Litigation
“What does ‘reasonable effort’ mean in a contract?”
The word reasonable is one of the most litigated terms in business law.
- Reasonable efforts to market a product
- Reasonable time to complete work
- Reasonable steps to secure financing
The problem is simple: what is “reasonable” to one party may feel “inadequate” to the other. Without clear metrics, expectations collapse and disagreements escalate.
A better approach is to define the actual duty, deadlines, or performance standards.
“Who is responsible for what?”
Contracts often assume everyone understands their role, but unless duties are spelled out carefully, each side may believe the other is responsible.
Examples we routinely see include:
- Construction contracts that don’t specify who handles permitting or inspections
- Operating agreements that fail to outline decision-making authority
- Real estate purchase agreements that do not detail repair obligations
- Service agreements that do not define the scope of services
When something goes wrong, each side points to the other, and the fight becomes expensive very quickly.
“What happens if two clauses say different things?”
This is one of the most common drafting mistakes we encounter.
A contract may say one thing in Section 4, and the opposite in Section 11. Or an earlier clause may impose a strict requirement, while a later clause relaxes that rule.
When the document contradicts itself, a court must determine:
- Which clause controls
- Whether the ambiguity was intentional
- Which interpretation is most consistent with the overall deal
This interpretation process can take years of litigation and hundreds of thousands of dollars in legal fees.
Contract Terms That Commonly Lead to Multi-Million Dollar Disputes
“What is included in the scope of work?”
When scope of work is unclear, everything else becomes unclear, deadlines, payments, change orders, warranties, and performance obligations.
In construction, this is where most disputes begin.
Common scope issues include:
- Missing specifications
- Vague descriptions of deliverables
- Lack of detail on materials or standards
- Undefined acceptance criteria
For multi-use or large commercial projects, ambiguity here often leads to delay claims, defect allegations, and cost-overrun disputes.
“How are profits, losses, and management rights handled?”
Small businesses often start with simple contracts, but as the company grows, vague language becomes a liability.
Common problem areas include:
- Undefined voting rights
- No process for breaking a deadlock
- Confusing distribution formulas
- Ambiguous buyout terms
- Lack of exit procedures
Partnership disputes are among the most emotional and expensive litigation matters. A well-drafted operating agreement prevents many of them.
“What if the parties disagree on performance?”
Many contracts fail to answer key questions:
- When exactly must payment be made?
- What triggers payment?
- What constitutes completed performance?
- What happens if delays occur?
Courts look for clarity. If it is not in the contract, they must fill the gaps, and that unpredictability often motivates lawsuits.
How Businesses Can Avoid Ambiguous Contract Language
“Do I actually need a lawyer to review my contract?”
In short, yes. Templates and AI tools can create a basic document, but they cannot anticipate real-world problems in your industry, your deal structure, or your specific risks.
Clear drafting requires:
- Defined duties
- Clear deadlines
- Consistent terminology
- Detailed performance standards
- Conflict-free clauses
- Custom terms tailored to your business
A business attorney is not there to complicate your contract; they are there to prevent costly court battles.
