Entire Agreement
Also: Merger Clause, Integration Clause, Entire Agreement Clause, Complete Agreement · Merger Clause, Integration Clause, Entire Agreement Clause, Complete Agreement, Integrated Agreement
An entire agreement clause states that the written contract is the complete and final agreement between the parties — replacing all prior discussions, negotiations, representations, and understandings.
It is intended to prevent either party from later claiming that something said or agreed to before the contract was signed is part of the deal.
Lawyer Explanation
An entire agreement clause — also called a merger or integration clause — is a boilerplate provision stating that the written contract constitutes the entire agreement between the parties and supersedes all prior negotiations, representations, and understandings.
The clause is intended to prevent the introduction of extrinsic evidence — such as prior emails, term sheets, or verbal discussions — to vary or supplement the written terms. It reinforces the parol evidence rule, which generally limits the use of evidence outside the written contract to interpret its terms.
However, entire agreement clauses do not necessarily bar all extrinsic evidence in all circumstances. Courts may still consider outside evidence in cases involving fraud, mistake, or ambiguity.
What It Actually Does
An entire agreement clause answers: "Is everything we agreed to actually in this document, or can one of us later point to something that was said during negotiations?" For example, if a vendor made verbal promises during sales presentations that are not reflected in the final contract, an entire agreement clause may prevent the customer from later claiming those promises are binding.
Why It Matters
The entire agreement clause provides certainty. Both parties can rely on the written contract as the definitive statement of their obligations — without worrying that prior discussions or representations will be used to add or change terms.
For that reason, it is important to ensure that all agreed terms are actually reflected in the written contract before signing. Once the contract is executed, the entire agreement clause may make it difficult to rely on anything that was left out.
Example
During contract negotiations, a software vendor's sales representative promises that the platform will include a specific feature. The feature is not mentioned in the final written agreement.
After signing, the customer discovers the feature is not available. The vendor points to the entire agreement clause and argues that only the written contract terms are binding. The customer's ability to enforce the verbal promise may be significantly limited.
Common Language You May See
"This Agreement constitutes the entire agreement between the parties with respect to its subject matter and supersedes all prior and contemporaneous agreements, negotiations, representations, and understandings, whether written or oral, relating to such subject matter."
What Stewart Law Looks For
- Does the contract include an entire agreement clause?
- Does the clause supersede all prior agreements and representations?
- Are there any exhibits, schedules, or attachments that are incorporated by reference?
- Does the clause address oral modifications?
- Is there a separate no-oral-modification clause?
- Does the clause interact with representations and warranties made in the agreement?
- Are there any side letters or separate agreements that should be referenced?
- Does the clause address the effect of prior course of dealing or trade usage?
Common Red Flags
An entire agreement provision deserves closer attention when it:
- is signed after verbal promises were made that are not reflected in the written contract
- fails to incorporate by reference all exhibits, schedules, and attachments that are part of the deal
- conflicts with a separate side letter or supplemental agreement
- is used to disclaim representations that were material to the other party's decision to enter the contract
- fails to address whether prior agreements on related topics remain in effect
Perspectives
Customer / Buyer
The party relying on representations made during negotiations will generally want to ensure that all material promises are reflected in the written contract before signing — because the entire agreement clause may make it difficult to enforce anything that was left out.
Vendor / Seller
The party that made representations during negotiations will generally want a strong entire agreement clause to provide certainty that only the written terms are binding.
Florida & Federal Considerations
Florida
Florida courts generally enforce entire agreement clauses and apply the parol evidence rule to limit the use of extrinsic evidence to interpret unambiguous contract terms. However, Florida courts may consider extrinsic evidence in cases involving fraud, mutual mistake, or ambiguity.

Frequently Asked Questions
Does an entire agreement clause prevent all prior discussions from being considered?
Generally yes, for the purpose of interpreting the contract. An entire agreement clause is intended to prevent a party from relying on prior negotiations, representations, or understandings that are not reflected in the written agreement.
Can an entire agreement clause prevent a fraud claim?
Not necessarily. Courts in many jurisdictions, including Florida, may allow fraud or fraudulent misrepresentation claims to proceed even in the presence of an entire agreement clause, depending on the circumstances.
Does an entire agreement clause prevent amendments?
No. An entire agreement clause addresses what the contract currently contains, not whether it can be changed. Amendments are typically addressed in a separate amendment clause.
What is the difference between an entire agreement clause and a merger clause?
The terms are often used interchangeably. Both refer to a provision stating that the written contract represents the complete and final agreement between the parties.
Can verbal agreements made after the contract is signed override an entire agreement clause?
Verbal modifications may or may not be effective depending on the contract and applicable law. Many agreements include a no-oral-modification clause requiring amendments to be in writing.
Have a Contract Using These Provisions?
Contract language operates as part of the agreement as a whole.
