A text message can be a legally binding agreement in Texas. Texas treats electronic records and electronic signatures as the equivalent of paper and ink, so a text thread that contains the pieces of a real contract can be enforced like any other. The harder questions are whether your particular exchange has those pieces, whether the deal is one the law still insists be in writing, and whether you can prove in court that the messages say what you say they say.
What the Text Has to Contain
A binding agreement needs the same core elements no matter the medium. Someone has to make an offer specific enough that the other person can simply say yes. The other party has to accept those exact terms; a reply that changes the price or the timing is a counteroffer, and the original offer is gone. Each side has to exchange something of value, whether money, goods, services, or a promise for a promise. Both parties have to intend to be bound, both have to be legally competent adults, and the subject of the deal has to be lawful.
In a text thread, that usually means the messages need to name what’s being exchanged, the price, and any deadline or condition, and one party has to clearly agree. “Sounds good” attached to a vague thread is thin. “Yes, I’ll pay $3,000 for the equipment, picked up Friday” is not.
Why Texas Treats a Text as a Writing
Texas adopted the Uniform Electronic Transactions Act, codified in Chapter 322 of the Business and Commerce Code. A record or signature cannot be denied legal effect just because it’s electronic; if a law requires a writing, an electronic record satisfies it, and if a law requires a signature, an electronic signature works. The statutory definitions are broad. An electronic record is any record created, sent, received, or stored electronically. An electronic signature is any electronic sound, symbol, or process attached to a record and adopted by a person with the intent to sign.1State of Texas. Texas Business and Commerce Code Chapter 322 – Uniform Electronic Transactions Act – Section: 322.002 A text sits comfortably inside the first definition, and typing your name, or a reply like “Agreed” or “Deal,” can satisfy the second if you meant it to confirm the arrangement.
UETA only applies when both parties have agreed to conduct business electronically, but Texas doesn’t require a formal opt-in. Courts look at the surrounding circumstances and the parties’ conduct.2State of Texas. Texas Business and Commerce Code Chapter 322 – Uniform Electronic Transactions Act – Section: 322.005 Trading terms back and forth by text is itself evidence that you both chose to deal electronically.
Federal law layers on top. The Electronic Signatures in Global and National Commerce Act says a signature or contract in a transaction affecting interstate commerce cannot be denied legal effect solely because it’s electronic.3Office of the Law Revision Counsel. 15 USC 7001 – General Rule of Validity Between UETA and ESIGN, the underlying rule that a text can carry a contract is settled.
Deals That Still Have to Be in Writing
Most everyday agreements in Texas are enforceable even when nothing is written down. But the Statute of Frauds, in the Texas Business and Commerce Code, requires certain higher-stakes deals to be in writing and signed by the person being held to them. A text thread can satisfy this requirement, but only if the messages actually contain the essential terms and show a clear intent to be bound.
The categories that require a signed writing include:
- Sales or transfers of an interest in real property.
- Residential or commercial leases running longer than one year.
- Any contract that by its own terms cannot be performed within one year of being made.
- A promise to pay another person’s debt.
- Agreements made in consideration of marriage, including prenuptial agreements.
- Certain commission agreements for the sale of oil, gas, or mineral interests.
- Loan agreements from a financial institution above $50,000.
There is also the sale of goods worth $500 or more. Under the Texas version of the Uniform Commercial Code, that contract isn’t enforceable without a writing that identifies the deal and is signed by the party being held to it.4Texas Public Law. Texas Business and Commerce Code Section 2.201 – Formal Requirements Statute of Frauds Selling a used laptop for $600 by text technically falls inside that rule, even though it feels casual.
For any of these categories, the practical point is that a text exchange has to do the work a formal contract would do: identify the property or goods, state the price, and show that both sides agreed. A thread that reads like negotiation without a clear “yes” will usually fail if challenged.
What a Text Cannot Do
Some documents fall outside electronic execution entirely. Texas UETA does not apply to wills, codicils, or testamentary trusts, so you cannot make or execute a will by text.5State of Texas. Texas Business and Commerce Code Chapter 322 – Uniform Electronic Transactions Act – Section: 322.003 Federal law excludes court orders, official court documents, and pleadings, along with family law matters like adoption and divorce and certain consumer notices such as foreclosure or eviction notices on a primary residence and cancellations of health or life insurance.6Office of the Law Revision Counsel. 15 USC 7003 – Specific Exceptions For those, a text has no legal force no matter how clearly the parties expressed themselves.
Proving the Agreement Existed
Having a valid text-based contract is one thing; getting a court to accept the messages as evidence is another, and this is where most disputes actually turn. Texas Rule of Evidence 901 requires the party offering evidence to produce enough proof that the item is what they claim it is.7Texas Evidence. Texas Rules of Evidence – Rule 901 Authenticating or Identifying Evidence For a text, that means showing who sent it, who received it, and that the content is unaltered.
A matching phone number is a starting point, not an answer. Phones get borrowed, lost, and stolen. Courts want “something more” tying the message to the specific person.
Ways to Authenticate
The simplest path is testimony from a participant in the conversation. A witness can confirm they sent or received the messages, and Rule 901 is satisfied. When direct testimony isn’t available, Rule 901(b)(4) allows authentication through distinctive characteristics, meaning the appearance, contents, and internal patterns of the messages read alongside all the surrounding circumstances.7Texas Evidence. Texas Rules of Evidence – Rule 901 Authenticating or Identifying Evidence Texts that reference details only the sender would know, discuss ongoing matters between the parties, or use language and nicknames the person actually uses are more likely to be authenticated. Conduct after the exchange matters too. Someone who denies agreeing to sell a car by text but handed over the keys and took the payment has confirmed the deal by their actions.
Screenshots Are Weak Evidence
Most people reach for screenshots first. They’re better than nothing, but they’re photographs of a screen, with no built-in proof that the conversation happened as shown. Fake text generators and image editors are widely available, and the other side’s lawyer will say so. Screenshots also lack the forensic metadata a proper extraction carries.
Stronger evidence comes from a forensic extraction of the device, which pulls the messages along with timestamps, sender and recipient data, and delivery information. Cellular carriers keep records of text message metadata that can be reached by subpoena. For a high-value dispute, a digital forensic expert can produce a verified extraction; that service typically runs $250 to $350 an hour or more.
How to Close a Deal by Text Without Regretting It
If you’re going to use text messages to make real agreements, treat the thread with the same care you’d give a written contract. The informality is the risk.
- Spell out every essential term: price, what’s being exchanged, deadlines, and any conditions. “Sounds good” without specifics invites arguments later.
- Get an explicit confirmation. “Do you agree to pay $3,000 for the equipment, picked up by Friday?” answered with “Yes, agreed” is much stronger than a thumbs-up.
- Type your full name when confirming a deal. It strengthens the argument that you intended to sign electronically.
- Preserve the whole conversation. Don’t delete messages, and back them up somewhere beyond the phone itself. Cloud backups, exported logs, and carrier records all outrank screenshots.
- For anything involving real estate, large sums, or long-term obligations, use the text exchange as a starting point and then put the deal in a formal signed contract. The thread might technically satisfy the Statute of Frauds, but a clean written agreement removes the ambiguity that fuels litigation.
The law is on the side of enforcing text-based agreements. What decides real cases is whether the messages contain enough to show a deal and whether you can prove they are what you say they are. Handle both, and a text is as binding as any signed page.
