Can Emails and Text Messages Form a Binding Contract in Texas?

The short version

Texas treats an electronic agreement like a paper one. The question a court asks about an email chain is the same question it asks about a letter: did the parties agree on the essential terms, and did they intend to be bound? If yes, the fact that the agreement lives in an inbox or a phone does not matter. If the agreement is of a type the statute of frauds requires in a signed writing, the electronic record and an electronic signature can satisfy that requirement too.

The Texas law that makes electronic agreements enforceable

The Texas Uniform Electronic Transactions Act (UETA), Business and Commerce Code chapter 322, has three provisions that decide most disputes:

• Section 322.007(a): a record or signature may not be denied legal effect or enforceability solely because it is in electronic form.
• Section 322.007(c): if a law requires a record to be in writing, an electronic record satisfies the law.
• Section 322.007(d): if a law requires a signature, an electronic signature satisfies the law.

The Act applies only to transactions between parties who have agreed to conduct the transaction by electronic means, and section 322.005 says that agreement is determined from the context and surrounding circumstances, including the parties' conduct. Two businesses that negotiate a deal entirely by email have, by that conduct, agreed to deal electronically. Federal law points the same way: the E-SIGN Act, 15 U.S.C. section 7001, provides that a signature, contract or record may not be denied legal effect solely because it is in electronic form.

When does an email thread become a contract?

When it contains the same things any contract needs: an offer, an acceptance of that offer on its terms, agreement on the essential terms (parties, subject, price or compensation, the core obligations), and an intent to be bound. Courts read the whole exchange, not a single message. A thread in which one side proposes terms, the other replies "agreed, please proceed," and work begins is a contract. A thread in which the parties keep adjusting the price and scope with no message closing the loop is a negotiation.

Texas courts have read a typed name at the end of an email, and in at least one appellate decision the sender's name in the "from" field, as a signature for statute of frauds purposes, because the UETA defines an electronic signature as any electronic sound, symbol or process attached to or logically associated with a record and executed or adopted with the intent to sign. Other Texas decisions have declined to treat an automatic signature block as a signature where nothing showed the sender intended it as one. The deciding fact in those cases is intent, which is shown by the content of the message, not by the formatting.

Text messages

The analysis is the same, and the problems are practical. Texts are short, so the essential terms are often spread across many messages or left to an earlier call. Threads get deleted, phones get replaced, and screenshots can be challenged as incomplete. A text exchange that says "Can you do the install for 14,500 by the 20th?" and "Yes, send the deposit" is as much a contract as the same exchange by email. A text that says "sounds good, let's talk tomorrow" is not.

Preserve the complete thread, with dates and the counterparty's number, as soon as a dispute is possible. Exporting the conversation from the phone, rather than taking screenshots, produces a record that is far easier to authenticate.

Example

Suppose a Dallas event company emails a venue: "Confirming the ballroom for March 14, 6 to 11 p.m., $9,800 all-in, setup from 2 p.m., per your proposal. Please confirm and we will send the deposit." The venue's events manager replies from her business account: "Confirmed. Invoice for the deposit attached. Thanks, Dana." The deposit is paid. Two months later the venue tells the company it has double-booked the date. The exchange identifies the parties, the date, the time, the price and the scope; the reply accepts without conditions; the typed name is a signature under the UETA; and the deposit is performance. The venue has a contract to answer for. Whether the event company can recover the cost of a replacement venue depends on the damages rules discussed in what damages a business can recover for breach of contract in Texas.

What makes an electronic agreement fail

• A missing essential term. If price, scope or quantity was never settled in the messages or anywhere else, there is no contract to enforce. For goods, section 2.201 of the UCC requires the writing to state a quantity.
• An express reservation. "Subject to a definitive agreement," "non-binding," or "for discussion" in the thread.
• No acceptance. A counter-proposal is a rejection. If the last message changed a term and no one agreed to the change, the parties never met.
• Lack of authority. The person emailing may not have had authority to bind the company. Apparent authority often fills the gap when the counterparty reasonably relied on the person's role, but it is a fact question.
• A contract clause requiring signed amendments. Many written contracts say changes must be in a signed writing. Whether an email exchange satisfies that clause depends on its wording and on the UETA's treatment of electronic signatures, and it is contested often enough that the question should go to counsel before anyone relies on an emailed change.

How this interacts with the statute of frauds

The statute of frauds, Business and Commerce Code section 26.01, makes some agreements unenforceable without a signed writing: real estate sales, agreements not performable within a year, guaranties and others. Under the UETA, an email or text that contains the essential terms and carries an electronic signature can be that writing. This is why a real estate deal, a multi-year services agreement or a personal guaranty negotiated by email can be enforceable even though no paper was signed, and also why a careless email can bind a party to a deal it thought was still open. The categories and the exceptions are covered in whether a verbal business agreement is enforceable in Texas.

Practical rules for both sides

If you want to be bound, write the terms in one message, ask for a one-word acceptance, and keep the thread. If you do not want to be bound yet, say so in every message that discusses terms. If a counterparty is relying on an emailed agreement against you, read the whole thread for an unaccepted change, a reservation, or a missing term before conceding there was a contract. And if the dispute is already live, preserve the mailbox and the phone; the metadata that shows who sent what and when is often the most persuasive evidence in the case. Guidance on what to keep is in what evidence to save before suing.
