Yes. Under the federal Electronic Signatures in Global and National Commerce Act (E-Sign Act), a record or signature cannot be denied legal effect just because it is electronic, and an electronic record satisfies any legal requirement that something be “in writing.”1Office of the Law Revision Counsel. United States Code Title 15 – Section 7001 So the short answer to whether a text message counts as being in writing is yes. Whether a particular exchange is enforceable is a separate question, and it turns on what the messages say, what both sides intended, and whether the subject matter falls into a category with special rules.
The Law Behind It
Two statutes do the work here. The E-Sign Act applies to any transaction affecting interstate commerce. The Uniform Electronic Transactions Act (UETA) has been adopted by 49 states plus the District of Columbia. Both say the same core thing: an electronic record satisfies a legal writing requirement, and a contract cannot be tossed out solely because it was formed with electronic signatures or records.1Office of the Law Revision Counsel. United States Code Title 15 – Section 7001
The definition of “electronic signature” under both laws is deliberately broad. It covers any electronic sound, symbol, or process attached to a record with the intent to sign. A typed name at the end of a text, a reply saying “agreed” or “deal,” even an emoji can qualify, as long as the context shows the sender meant to commit.
One nuance. The E-Sign Act adds a stricter consent step when a business sends a consumer a document that a law requires to be “in writing,” like a mandatory disclosure. The consumer has to affirmatively agree to receive that record electronically first.1Office of the Law Revision Counsel. United States Code Title 15 – Section 7001 For ordinary contracts between two people or two businesses, no formal consent step is required. If both sides are already negotiating by text, that conduct itself shows they agreed to transact electronically.
When a Text Message Becomes a Binding Contract
A text exchange becomes a contract when it has the same ingredients any contract needs: an offer, acceptance, consideration (something of value changing hands), and a shared intent to be bound. The medium is irrelevant. What matters is whether the messages spell out definite terms and show both sides understood they were making an enforceable deal.
A landscaper texts a homeowner, “I’ll mow your lawn every week in July for $500 total.” The homeowner replies, “Sounds good, let’s do it.” Clear offer, unambiguous acceptance, consideration on both sides. A court reviewing those messages would likely find a binding agreement.
Compare that to “I can probably help with the yard sometime.” No price, no scope, no commitment. Courts consistently reject those loose exchanges because they lack definite terms.
Watch Your Wording
Accidental contracts by text are a real risk, especially in business. A manager who texts a candidate “You’re hired at $80K, start Monday” may have created enforceable employment terms even if HR has not run its process. Replies like “that works,” “yes,” and “deal” can each function as acceptance when the message before them laid out specific terms.
If a conversation is preliminary and you don’t want it to lock you in, say so. A line like “this is just for discussion, any deal needs a signed contract” makes your intent clear. For anything significant, moving negotiations out of text and into a formal agreement is the simplest way to avoid surprises.
Contracts That Must Be in Writing
Certain categories of contracts have to be in a signed writing to be enforceable, under a rule called the Statute of Frauds. The most common categories:
- Real estate sales and transfers, and any contract involving an interest in land.
- Agreements that cannot be completed within one year of when they are made.
- Promises to pay someone else’s debt if that person defaults.
- Sales of goods worth $500 or more, under the Uniform Commercial Code, which most states have adopted.2Legal Information Institute. Uniform Commercial Code 2-201 – Formal Requirements Statute of Frauds
- Leases longer than one year. Month-to-month arrangements generally don’t need a writing, but anything past a year typically does.
Text messages can satisfy these writing requirements. Courts have held that essential terms spread across multiple electronic messages can be read together as a single agreement. For a text exchange to hold up, it needs to include the key terms of the deal and be “signed” in the electronic sense by the person it is being enforced against. A few states have adopted a revised UCC with a higher dollar threshold than $500, so check your state’s version if a significant sale of goods is on the line.
Where a Text Message Won’t Do
Not everything can be handled by text. The E-Sign Act specifically carves out categories where electronic records and signatures do not satisfy legal requirements:3GovInfo. United States Code Title 15 – Section 7003
- Wills and testamentary trusts. Creating or modifying a will still requires compliance with your state’s formalities, which almost universally means a physical signature and witnesses. A handful of states have begun exploring electronic will legislation, but the E-Sign Act does not cover these documents.
- Family law matters. Adoption and divorce proceedings are governed by state rules that the E-Sign Act does not override.
- Court documents. Orders, notices, pleadings, and other official filings follow the court’s own execution and filing rules.
- Certain critical consumer notices. Cancellation of utility service, notices of default or foreclosure on a primary residence, termination of health or life insurance, and product safety recalls cannot be delivered solely as electronic records under the E-Sign Act.
- Documents that must accompany the transport of hazardous materials.
Most of the Uniform Commercial Code is also excluded, with the notable exception of the provisions covering sales of goods (Articles 2 and 2A).3GovInfo. United States Code Title 15 – Section 7003 A text can help seal a deal for buying equipment, but it cannot substitute for the formal requirements in areas like negotiable instruments or secured transactions.
Making Texts Hold Up in Court
Text messages show up as evidence in lawsuits constantly, but they don’t walk into the record on their own. Before a court will consider them, someone has to authenticate the messages, meaning prove they are genuine, unaltered, and actually sent or received by the claimed person.
Federal Rule of Evidence 901 and equivalent state rules list several accepted methods. The most direct is testimony from someone in the conversation confirming the messages are accurate. Another approach relies on distinctive characteristics in the messages: references to facts only the sender would know, the sender’s known phone number, habitual phrases or emoji, or a screen name tied to the person. Phone carrier records can corroborate dates, times, and numbers, though they typically don’t capture message content. Forensic analysis of the device can verify that messages have not been tampered with, which matters when the other side disputes authenticity.
Preserving Your Messages
Screenshots are better than nothing, but they are easy to challenge in court because they can be edited. If you think a text exchange might matter in a dispute, keep the originals on your device and back them up. Turning off auto-delete is a simple first step. For higher-stakes situations, a forensic extraction by a qualified technician creates a verifiable record that holds up much better than a photo of a screen.
Timing matters. Messages get lost when phones break, get replaced, or have their storage wiped. Collecting relevant texts the moment you anticipate a dispute dramatically improves your chances of using them later.
