You received a settlement offer from the insurance company and you are thinking about it, maybe for a few days, maybe longer. Or perhaps you verbally agreed to a number and now you are not sure whether that agreement actually means anything, or whether the insurer can simply change their mind before paperwork is signed. This question comes up more often than most people expect, and the answer turns on a few specific legal principles that determine whether an offer can be withdrawn, whether a verbal agreement is binding, and what happens if the insurer tries to reverse course after you have already said yes.

Start with offers that have not yet been accepted. Under basic contract law principles that apply in Missouri and everywhere else in the United States, an offer can generally be revoked by the offeror before it has been accepted by the offeree. An insurance company that sends you a written settlement offer has made a contract offer, and until you accept it, they retain the legal right to withdraw it. That is not a quirk of insurance law. It is a fundamental principle of how contract formation works: no contract exists until there is both an offer and an acceptance, and either party can change their position before that moment of mutual agreement is reached.

The practical implication of this is that sitting on a settlement offer longer than necessary carries real risk. Most settlement offers come with an explicit deadline. The letter or email from the adjuster often states that the offer is open for a specific number of days, after which it expires. If you allow that deadline to pass without responding, the offer is gone and there is no legal basis to compel the insurer to reinstate it at the same number. Some offers are presented without an explicit deadline, but even those can be revoked with reasonable notice before acceptance. An adjuster who calls to tell you the offer is being withdrawn before you have accepted it is, in most circumstances, legally entitled to do exactly that, regardless of how inconvenient the timing is for you.

Where things become more legally interesting is the moment of acceptance, and specifically what counts as acceptance under circumstances that are not always clean. If you verbally told the adjuster you accept the offer, does that create a binding agreement even before a written release is signed? The answer is yes, in most circumstances, though enforcing it can require litigation. A verbal acceptance of a settlement offer creates a contract under standard contract law principles. The written release that follows is documentation and formalization of the agreement, not the agreement itself. Courts in Missouri and most jurisdictions have consistently held that a settlement agreement is enforceable once the essential terms, the parties, the amount, and the scope of the release, have been agreed upon, even if the formal documentation has not been completed.

This principle cuts in both directions, and that symmetry is important. If you verbally accepted an offer and the insurance company subsequently tries to lower the number or withdraw the offer entirely, you have a legal basis to enforce the original agreement. But if you verbally accepted and then changed your mind because you realized you undervalued your injuries or because new medical information emerged, the insurer has the same basis to hold you to the acceptance. A verbal yes is not a soft maybe that you can revisit freely. It is an agreement that both parties are entitled to enforce, and treating it otherwise can lead to outcomes that are much worse than the settlement you accepted and then tried to walk back.

Here is the insight that most people negotiating with an insurance company have never fully considered: the timing of when you accept, and the precision with which the terms are stated at the moment of acceptance, matters enormously for what the settlement actually contains. An oral agreement that specifies a dollar amount but does not address which claims are being released, whether the release is limited to the specific accident or extends to all claims, and whether any liens or subrogation rights are addressed is an agreement with ambiguity built in. Ambiguity in a settlement agreement tends to be resolved in litigation, which is expensive, slow, and uncertain. The lesson is not to avoid oral acceptances entirely, because documented verbal agreements are binding. The lesson is to ensure that the essential terms are explicitly stated and confirmed in writing, even if that writing is a simple email to the adjuster confirming the specific terms as you understand them, before any change in circumstances can disrupt the deal.

Insurance companies sometimes attempt to withdraw or modify a settlement offer after a verbal agreement has been reached on grounds that the adjuster who made the offer lacked authority to settle at that amount. This argument surfaces more often than it should, and it is worth understanding its legal limits. An adjuster who is employed by the insurance company and who makes settlement offers in the ordinary course of their job has apparent authority to bind the company to those offers. The internal limits on an adjuster’s settlement authority are the insurer’s own internal business arrangement and are not something the claimant has reason to know about. An insurer that allows an adjuster to negotiate and offer settlements, and then attempts to escape the resulting agreement by claiming the adjuster was not authorized to go that high, is typically making an argument that courts treat skeptically. The insurer created the appearance of authority by putting the adjuster in the role. The claimant who reasonably relied on that appearance is generally protected.

The more legitimate scenario in which an insurer may have grounds to revisit a settlement involves fraud or material misrepresentation in the claims process. If a settlement was reached based on information you provided that was materially false, the insurer can seek to rescind the agreement on grounds of fraud in the inducement. This is not an abstract theoretical scenario. It arises when claimants exaggerate injuries, falsify records, or misrepresent facts about the accident, and courts will not enforce settlement agreements that were obtained through fraudulent misrepresentation. This scenario is worth noting not because most claimants are engaged in fraud but because it illustrates that the finality of a settlement agreement has limits, and that those limits exist on both sides of the transaction.

Another scenario where an apparently final settlement can unravel involves situations where the release has not been signed and a significant change in circumstances occurs before execution. If you verbally accepted a settlement and then suffered a dramatic and unforeseeable worsening of your injuries before signing the release, some courts will consider whether the agreement should be set aside if the new information fundamentally changes the basis on which you accepted. This is a narrow doctrine, applied cautiously, and it does not mean that normal post-acceptance second thoughts justify walking away from a verbal agreement. It applies when something genuinely extraordinary has occurred that neither party could have anticipated, and even then it is not guaranteed to succeed.

From a practical standpoint, the most useful thing to know about the revocability of settlement offers is that the window between offer and acceptance is the period of maximum risk on both sides. During that window, the insurer can withdraw and you can decline, but once acceptance occurs the dynamic shifts to contract enforcement. That shift protects you from a low offer being taken off the table after you accept, and it obligates you to honor an acceptance you gave before you fully thought through whether the number was right. Moving thoughtfully but not slowly within that window, seeking any additional information you need before committing, and confirming the key terms in writing at the moment of acceptance are the three habits that eliminate most of the problems that arise in this area.

If an insurance company tells you that a settlement offer you accepted, verbally or in writing, is being withdrawn, the appropriate response is a written communication sent immediately that documents your acceptance and states specifically that you are holding the insurer to the agreement. Copy that communication to your attorney if you have one. If the insurer refuses to honor the agreement, a motion to enforce the settlement in the relevant court is the legal mechanism for compelling performance, and courts take a dim view of parties who enter settlement agreements and then attempt to escape them without legal justification. The offer you accepted may be more binding than the adjuster who is calling to take it back would like you to believe.

This article is intended for general informational purposes only and does not constitute legal advice. The enforceability of settlement offers and verbal acceptances, the authority of insurance adjusters, and the legal standards governing settlement agreement rescission vary by state and by the specific facts of each case. If an insurance company has attempted to withdraw or modify a settlement offer you accepted, consult with a licensed personal injury attorney in your state as soon as possible before responding to the insurer.
