The Texas Option Period: Your Right to Walk Away (2026)

The option period is the most valuable thing in your contract, and most of what you will read about it online is describing a form that no longer exists.

It is the window in which you can walk away from a Texas home purchase for any reason at all, or no reason, and get your earnest money back. It is also governed by a set of rules where the details decide everything, and the details changed three weeks ago.

The Contract Changed on July 1, 2026

The current One to Four Family Residential Contract (Resale) is TREC No. 20-19, effective July 1, 2026. It replaced 20-18. If you signed something earlier this year, you signed a different form. TREC publishes the form itself at that link, which is worth reading rather than taking anyone’s summary of, this one included.

Two corrections worth making immediately, because they are the two things stale guides get wrong most often:

• The termination option is paragraph 5B, not paragraph 23.It has not been paragraph 23 since April 2021. In the current form, paragraph 23 is “Consult an Attorney Before Signing.” Any article that points you to paragraph 23 for your walk-away right is five years out of date, which tells you what to make of the rest of it.
• The option fee goes to the escrow agent, not the seller. Also changed in April 2021. Paragraph 5A requires delivery to the escrow agent named in your contract - the title company - made payable to them, within 3 days after the effective date. Earnest money and option fee may be paid separately or combined in one payment.

I am starting here rather than with the concept because a buyer acting on either of those stale rules can lose the protection entirely, and the loss is not recoverable.

What the Option Period Actually Is

Paragraph 5B grants the buyer the unrestricted right to terminate the contract by giving notice to the seller within the negotiated number of days after the effective date. Unrestricted means exactly that. You do not need a reason, you do not need an inspection finding, and you do not need the seller to agree.

Terminate within the window and the outcome is split:

• The option fee is not refunded. It never is. That is what you bought.
• The earnest money is refunded to you.

Notice must be given by 5:00 p.m. local time where the property is located on the date specified. And if you close instead, the option fee is credited to the sales price automatically under paragraph 5A(4) - there is no longer a box anyone has to remember to check.

How the Days Are Counted

Calendar days, not business days. The effective date is day zero and counting starts the next day. An effective date of November 1 with a 10-day option period expires November 11 at 5:00 p.m.

Now the asymmetry that catches people, and it is the single most important paragraph on this page:

• Delivery deadlines roll forward. Under paragraph 5A(2), if the last day to deliver the earnest money, the option fee, or additional earnest money falls on a Saturday, Sunday, or Legal Holiday, it extends to the end of the next day that is not one of those.
• The end of the option period does not roll forward. Paragraph 5B contains no such clause. If your option expires 5:00 p.m. on a Sunday, it expires 5:00 p.m. on that Sunday. Paragraph 5E states that time is of the essence.

The 20-19 form also, for the first time, defines “Legal Holiday”rather than leaving it as an undefined lowercase term. It means the holidays in Texas Government Code sections 662.003(a) and 662.003(b)(4) and (6): New Year's Day, MLK Day, Presidents' Day, Memorial Day, Juneteenth, July 4, Labor Day, Veterans Day, Thanksgiving, the Friday after Thanksgiving, and Christmas Day.

Read that list carefully for what is missing. It deliberately excludes several Texas state holidays - Texas Independence Day, San Jacinto Day, Confederate Heroes Day, LBJ Day, December 24 and December 26. Those are state holidays but they are not Legal Holidays for this contract, so no deadline rolls off them. A buyer who assumes March 2 buys them a day is wrong.

The Blank That Voids the Right

Paragraph 5D is short and it is the one I would tattoo on a first-time buyer:

If no dollar amount is stated as the option fee or if Buyer fails to deliver the option fee within the time required, Buyer shall not have the unrestricted right to terminate.

Two separate failures, one outcome. A blank left unfilled on the form is as fatal as a late payment. You would still be under contract, still bound to the closing timeline, still holding your financing and title contingencies - but without the clean walk-away right you believed you had purchased.

This is genuinely the most common way buyers lose their option protection, and it is entirely preventable. Check that the amount is written in, and get proof of delivery to the title company with a timestamp. Not a promise that it was sent. Proof.

What You Can Do With the Time

Under paragraph 7A the seller must permit you and your agents access at reasonable times, and must turn existing utilities on at their expense and keep them on while the contract is in effect. You may have the property inspected by inspectors you select who are licensed by TREC.

One carve-out matters a great deal in slab country: hydrostatic testing must be separately authorized by the seller in writing. You cannot order it unilaterally. That is worth knowing before you need it, because a plumbing leak under a slab is one of the common causes of foundation movement here, and it is precisely the test you would want if the inspector flags something. Ask early, in writing, rather than discovering the restriction on day eight of a ten-day option.

Foundations: The North Texas Question

This is the local anxiety, and it is grounded in real geology rather than folklore. The Blackland Prairie is dominated by Houston Black clay, the Texas state soil: 40 to 60 percent clay, high shrink-swell potential, with cracks half an inch to four inches wide at a foot down that stay open 90 to 150 days a year (USDA-NRCS Official Series Description).

The exposure is not evenly spread, and the difference matters when you are deciding how many days to ask for. On NRCS soil survey data, Collin County is roughly twice Denton County's exposure to very high shrink-swell soil - 67.6% of mapped acreage against 31.9%. That is a real difference in the base rate of soil-driven movement, and it is a reason to build inspection time into the option period in Collin rather than a reason to avoid a county. The county-by-county breakdown and the geology behind it are in the North Texas foundation guide; what follows here is only what it means for your option clock.

Now the part that determines what you actually learn, and it surprises nearly everyone:

• Your inspector must tell you whether the foundation is performing. Under 22 TAC 535.228(a) he shall render a written opinion as to performance, and report visible indications such as doors that will not latch, sloping floors, and cracking masonry cladding.
• Your inspector may not tell you what caused it or how to fix it. The Texas Board of Professional Engineers, in Advisory Opinion 43, holds that analyzing the cause of a condition or recommending repair is the practice of engineering. A TREC inspector cannot give an engineering opinion on a foundation unless he also holds a PE license.

So the sequence is: inspector flags movement, structural engineer explains it. That second engagement costs money and takes days, which is the practical argument for negotiating an option period long enough to absorb it rather than the shortest one that wins the offer.

Two consequences worth knowing before you get there. Fannie Mae will not purchase a loan on a property rated C6, and evidence of abnormal settlement requires appraiser comment plus a professionally prepared report (Selling Guide B4-1.3-06). And on the insurance side, the Texas Department of Insurance notes that earth movement is generally excluded and that foundation and slab damage is an optional endorsement, not standard coverage. Check your policy rather than assuming.

What none of this gives you is a repair number, and you should be suspicious of anyone who offers one inside your option window. There is no credible published DFW per-pier pricing, and contractor estimates on the same house differ by roughly tenfold - the reasoning is set out in the foundation guide. The option-period consequence is what matters here: getting two real bids takes days, so if a foundation question is live on your house, that is the thing your remaining days have to be long enough to cover.

Where Your Earnest Money Sits

The escrow agent holds it. Under paragraph 18A they are not a party to the contract, are not liable to pay interest on it, and may condition disbursement on collection of good funds.

Once the option period expires, the earnest money is genuinely at risk - but only on default, which is narrower than most buyers assume. Paragraph 15 lets the seller terminate and receive it as liquidated damages if you fail to comply, and the remedy is symmetric if the seller defaults. What it does not mean is that every post-option exit costs you the money: the financing contingency, the title objection right in paragraph 6D, and the casualty provision in paragraph 14 can all still return it.

One procedural detail worth carrying: under paragraph 18C, if one party makes a written demand for the earnest money and the other raises no written objection within 15 days, the escrow agent may disburse. Silence is not a neutral position in a dispute. Object in writing, on time.

The Termination Right Nobody Mentions

Here is the part almost no buyer guide covers, and it can outlive your option period entirely.

Texas Property Code §5.008 requires the seller to give you a written Seller's Disclosure Notice. Paragraph 7B of the contract attaches a remedy to it:

• If you never receive the notice, you may terminate at any time prior to closing and the earnest money is refunded.
• If the seller delivers it late, you may terminate for any reason within 7 days after you receive it, or before closing, whichever comes first.

That is a second, independent walk-away right, and it is not bounded by your option window. If a disclosure lands on day twenty of a contract with a ten-day option, you have a fresh seven-day right from that moment.

The disclosure forms also just changed. TREC No. 55-1 took effect May 28, 2026, adding disclosures for insurance, private roads the buyer would maintain, aboveground storage tanks, and conservation easements. And a brand-new mandatory form, TREC No. 61-0, Seller's Disclosure about Groundwater and Surface Water Rights, took effect July 1, 2026 and is wired into the contract at the new paragraph 7I. If you are selling rather than buying, the cost-of-selling guide covers what the new disclosure asks of you.

None of this is a substitute for legal advice, which is exactly what paragraph 23 now says. But knowing which paragraph your rights live in, and which deadlines move for a weekend and which do not, is the difference between using the option period and merely having one.
