You can say no. Here's what actually happens next.

Do you have to accept the insurer's first offer?

No. Nothing in Texas law or your policy requires you to take the first number, and adjusters expect informed owners to check it. Before you respond at all, verify the offer: request the full valuation report and audit the actual cash value behind it. Most lowball settlements fail that audit on comparables, trim, options, or condition.

What happens to your claim when you say no?

The claim stays open. Declining an offer is the normal first step of a value dispute, not a breach of anything: you respond in writing that you disagree with the valuation, state what you believe the vehicle is worth, and attach your evidence. The insurer must still handle the claim under the Texas Prompt Payment of Claims Act (Insurance Code Chapter 542), and if it accepts liability but drags its feet paying what's owed, statutory interest of 18% per year plus attorney's fees can attach. Saying no does not give the insurer a reason to close the file - and a covered claim can't be denied simply because you disagreed about the amount.

Where the real pressure comes from

The leverage against you isn't legal - it's logistical. Three costs quietly accrue while you decide, and each one has a counter:

• Rental coverage runs out. Policies cap rental by days and dollars, and many insurers stop paying a set number of days after the offer. Ask in writing exactly when your rental coverage ends.
• Storage fees stack up. If the car sits at a tow yard, daily storage charges accrue and can get pushed back onto you. Authorize the move to a free or insurer-arranged location - moving the car doesn't mean accepting the offer.
• The loan doesn't pause. Payments stay due while you dispute, so keep making them; missed payments hurt you, not the insurer.

Plan for those three and the "take it now" urgency loses most of its teeth.

Can you take the undisputed amount and keep disputing?

Often, yes - ask the insurer in writing to pay the undisputed portion of the claim while the disagreement over the remainder continues. That relieves the loan and replacement-car pressure without surrendering the dispute. One caution: read anything you sign or endorse. If a check or release is presented as full and final settlement of the claim, signing it can end the fight - so confirm in writing that a partial payment is exactly that, partial.

What are your options instead of accepting?

1. Counter in writing with documented evidence: local comparable listings, the window sticker or build sheet, maintenance records, pre-loss photos.
2. Get an independent vehicle value report. It rebuilds the value from verified local comparables and documents every correction - our total-loss packages start at $99 with 48-hour standard delivery.
3. Invoke the appraisal clause. Texas personal auto policies issued or renewed on or after January 1, 2026 must include one under SB 458; many earlier policies have one too. See the right-to-appraisal guide.
4. File a TDI complaint if the insurer is stonewalling or missing Chapter 542 deadlines.
5. Go to court if you must: justice court handles disputes up to $20,000, and an attorney makes sense for larger claims.

The full playbook, from valuation report to written counter, is in the step-by-step totaled car guide.

How long do you have to decide?

There is no general statutory deadline forcing you to accept an offer by a particular date - adjuster urgency is a tactic, not a law. Your real deadline is the limitations period: Texas claims are generally subject to two years from the date of loss. That is plenty of time to spend a week verifying the number, and not enough time to let a dispute drift for a year. Move deliberately, in writing, and keep the practical costs above in view.
