Contract Defined Terms Checker: Find Missing Definitions in 60 Seconds

Undefined terms invite disputes. Traditional review takes 30-60 minutes. AI does it instantly.

By Chandler Supple3 min read

Contract definitions establish precise meanings for key terms, preventing interpretation disputes. Capitalized terms typically signal defined terms with specific meanings. Traditional review requires identifying all capitalized terms and checking whether definitions exist—this takes 30-60 minutes per contract. AI-powered defined term finders scan contracts instantly, highlighting undefined terms and flagging inconsistencies.

What the AI Checks

Defined Terms Analysis

Check Type What It Finds Why It Matters
Undefined capitalized terms"Services" used but not definedCreates ambiguity and dispute risk
Inconsistent capitalization"Services" (15x) vs "services" (8x)Suggests drafting error
Unused definitions"Subsidiary" defined but never usedClutters contract unnecessarily
Cross-reference gapsDefinition uses "Trade Secrets" which isn't definedIncomplete definition chain

Common Definition Problems

Undefined Terms That Cause Disputes

Undefined Term Why It's Problematic What to Define
"Confidential Information"Parties disagree on what qualifiesCategories of protected information
"Deliverables"Scope disputes about what's includedSpecific items, formats, and quantities
"Services"Uncertainty about scope of workSpecific services covered by agreement
"Intellectual Property"Ownership disputesWhat IP is addressed and how
"Material Breach"When termination rights ariseSpecific triggers for breach

Definition Best Practices

  • Capitalize consistently: Defined terms always capitalized; non-defined terms always lowercase
  • Define on first use: Or in consolidated definitions section
  • Use specific terms: "Confidential Information means..." not vague descriptions
  • Remove unused definitions: If never used in agreement body, delete
  • Check cross-references: Terms used in definitions must also be defined

AI Comment Format

**Undefined term flagged:**
[Services] - This capitalized term is used 15 times but not defined. Add definition or decapitalize if general meaning intended.

**Inconsistent capitalization:**
"Services" (15 uses) vs "services" (8 uses) - Standardize capitalization. If defined term, always capitalize. If not, always lowercase.

**Unused definition:**
"Subsidiary" is defined but never used in agreement body. Remove definition or add provisions addressing subsidiaries.

**Cross-reference gap:**
"Confidential Information" definition references "Trade Secrets" which is not defined. Add Trade Secrets definition.

Bidirectional Checking

Forward and Reverse Analysis

Direction What It Does What It Catches
Forward checkFind capitalized terms → verify definitions existUndefined terms
Reverse checkFind definitions → verify terms are usedUnused definitions

Both directions matter. Forward check prevents undefined terms. Reverse check prevents unnecessary definitions cluttering the contract.

Frequently Asked Questions About Defined Terms

Do all capitalized terms need definitions?

No—proper nouns, titles, and sentence starters don't need definitions. "California" doesn't need defining. "Customer" probably does. AI should distinguish between terms needing definition and proper nouns that don't.

Should AI suggest definition language?

For common terms, yes; for deal-specific terms, no. AI can suggest standard "Confidential Information" definitions. But "Deliverables" must reflect the specific deal—AI should flag it as needing definition without guessing the content.

What about terms that appear in quotes or parentheses?

These are often definition signals. "The software ("Software")" or "confidential information (as defined below)" indicate definitions. AI should recognize these patterns and verify the corresponding definition exists.

How do I fix inconsistent capitalization?

Decide if the term needs definition. If yes, capitalize consistently throughout and add definition. If no, use lowercase consistently. Mixed capitalization is always wrong—it signals either missing definition or unnecessary capitalization.
