When a Handshake Deal Meets a Signed Contract<\/h1>

Side terms agreed over the phone or in passing can clash with the paperwork you already signed. Here is how business owners can sort out which terms still count.<\/p>

You signed a written contract, and later someone changed a term on a phone call or in a quick conversation. Now the other side says the new deal binds you, or you need it enforced.<\/p>\n

Whether an oral side agreement affects a written contract depends on the facts of each dispute, so it is worth discussing with a lawyer. The change has to meet basic contract rules, fit any limits in the written deal, and be provable.<\/p>\n

The Short Answer: Sometimes, But Not Automatically<\/h2>\n

A later oral change can hold in Florida when the basic requirements are met. Talking about a change is not the same as agreeing to one. The Florida Supreme Court held in St. Joe Corp. v. McIver<\/a> that an oral contract must meet the basics of contract law, including offer, acceptance, consideration and clearly stated essential terms.<\/p>\n

Whether the change holds depends on the facts. Four questions usually decide it:<\/p>\n

    \n
  1. Did both sides agree to specific new terms?<\/li>\n
  2. Does the written contract limit how it can be changed?<\/li>\n
  3. Does Florida’s statute of frauds require a signed writing?<\/li>\n
  4. Can you prove what was agreed?<\/li>\n<\/ol>\n\n

    How Florida Courts Look at an Oral Change to a Signed Contract<\/h2>\n

    Both sides have to agree to the new terms, and those terms have to be specific. A new price, a new deadline or a removed piece of work are the kinds of changes a court can point to. A vague remark like “we’ll sort out the rest later” usually won’t change the signed terms by itself.<\/p>\n

    Conduct matters too. When both parties start performing under the new terms, that performance can show they agreed. Accepting different payment without objection can also be read as agreement.<\/p>\n

    The reverse can catch businesses off guard. Under Flaherty v. Flaherty<\/a>, ratification occurs when a party entitled to rescind a voidable contract fails to do so after learning the facts that justify rescission. The same logic can apply when a business keeps performing a deal it later wants to challenge.<\/p>\n

    Written-Modification and Integration Clauses<\/h2>\n

    Many written contracts say how they can be changed. A common version says changes must be in writing and signed by both sides. That is often called a no-oral-modification clause. It gives you a clear point to argue from, but it doesn’t end the debate on its own.<\/p>\n

    Another common term is an integration clause. It states that the written document is the complete agreement.<\/p>\n

    So these clauses reduce disputes, but they don’t settle every one.<\/p>\n

    When the Statute of Frauds Blocks an Oral Change<\/h2>\n

    Florida’s statute of frauds can make an oral change unenforceable in certain categories. Under Fla. Stat. \u00a7 725.01<\/a>, no action may be brought on an agreement that is not to be performed within one year from when it is made, unless it is in writing and signed by the party to be charged. Fla. Stat. \u00a7 725.01<\/a> reads: “unless the agreement or promise upon which such action shall be brought, or some note or memorandum thereof shall be in writing and signed by the party to be charged therewith or by some other person by her or him thereunto lawfully authorized.” The same section covers contracts for the sale of land and leases longer than one year.<\/p>\n

    This matters when a side deal extends a multi-year contract or adds a long-term duty. A verbal promise to keep a service running for several years may fall within this rule. Whether it does turns on the wording and timing of the deal.<\/p>\n

    For goods, Fla. Stat. \u00a7 672.201<\/a>, as amended in 2025, says a contract for goods priced at $500 or more isn’t enforceable by action or defense unless there is a record sufficient to show a contract was made, signed by the party against whom enforcement is sought, with some exceptions. Between merchants, if within a reasonable time a written confirmation sufficient against the sender is received and the receiving party has reason to know its contents, it can satisfy this rule unless the receiving party objects in writing within 10 days.<\/p>\n

    Businesses also argue promissory estoppel, saying they relied on a promise. In DK Arena, Inc. v. EB Acquisitions I, LLC<\/a>, the Florida Supreme Court held that this doctrine can’t be used to get around the statute of frauds. Reliance alone doesn’t make an oral promise enforceable when the statute requires a writing.<\/p>\n

    The Proof Problem: Showing What Was Said and Agreed<\/h2>\n

    Without records, it often becomes your word against theirs. Records give your account something solid to stand on.<\/p>\n

    Evidence that often supports a side deal includes:<\/p>\n
