Lyda v. Allstate, insurer intervention, and the reshaping of § 537.065 litigation in Missouri.
Missouri Injury & Insurance Law | missouriinjuryandinsurancelaw.com
I. The Issue
Lyda v. Allstate is likely the most consequential Missouri appellate decision to date on the post-2021 operation of § 537.065. The opinion appears to hold that once an insurer intervenes under § 537.065.4, the plaintiff and insured may no longer resolve the underlying tort case through a bilateral settlement that cuts off the insurer’s ability to litigate liability and damages. That holding materially changes how § 537.065 agreements function in practice.
For Missouri practitioners, the decision shifts the focus from whether a § 537.065 agreement should be used to whether it should be avoided and if used when is best —and what happens if it is not completed before intervention occurs. It also raises a set of practical questions about how these cases will now be tried once the insurer becomes an active participant in the tort case.
II. The Case: Lyda v. Allstate Fire and Casualty Insurance Company
On September 22, 2019, Mark Northcott was driving a golf cart through Incline Village, a private gated subdivision in Foristell, Warren County, Missouri. Connie Lyda was a passenger. Northcott lost control, crashed, and ejected Lyda—who suffered serious injuries, including large skin avulsions exposing tendons and bone, a hand fracture, and significant facial lacerations requiring multiple surgeries and skin grafting. Northcott’s blood alcohol measured .114 hours after the crash.
Northcott carried two Allstate policies: an auto policy through Allstate Fire and Casualty, and a homeowner’s policy through Allstate Vehicle and Property. When Lyda sued Northcott in January 2023, he tendered the defense to Allstate. Allstate’s response was to refuse a defense without a reservation of rights and then deny coverage altogether. By March 2023, Allstate had filed its own lawsuit in federal court seeking a declaratory judgment that it owed Northcott nothing—neither defense nor indemnity—under either policy.
Left without a defense and facing personal exposure, Northcott did what § 537.065 was designed to allow: he and Lyda entered into a § 537.065.1 agreement. Lyda agreed to forgo pursuing Northcott’s personal assets; Northcott agreed to admit the essential facts of liability, pursue coverage claims against Allstate, and assign Lyda 90% of any net recovery from those claims. Allstate was notified the same day the agreement was signed.
Allstate moved to intervene under § 537.065.4 on May 22, 2023, and the circuit court granted intervention in June 2023. Once inside the case, Allstate filed an answer denying liability, denying Northcott’s intoxication, denying causation, and asserting comparative fault and assumption of risk—directly contradicting the admissions its own insured had made. Northcott’s own answer admitted everything and prayed for judgment in Lyda’s favor.
In September 2024, Lyda and Northcott jointly moved for entry of judgment based on a $6,140,000 settlement. The circuit court granted the motion and entered judgment in October 2024. Allstate moved to vacate. In February 2025, the circuit court denied that motion and simultaneously granted Northcott partial summary judgment finding that the homeowner’s policy covered the accident. The circuit court certified both judgments for immediate appeal under Rule 74.01(b). Allstate appealed both.
II. The Court of Appeals’ Holding
The Western District of the Missouri Court of Appeals decided the case on March 24, 2026. Writing for a unanimous three-judge panel, Judge Alok Ahuja issued a decision that will have far-reaching consequences for how § 537.065 cases are litigated in Missouri.
A. The Tort Judgment Is Reversed
The court held that once Allstate intervened under § 537.065.4, Lyda and Northcott could no longer settle the underlying negligence claim without Allstate’s consent. The 2021 amendments to § 537.065.4 guarantee an intervening insurer ‘all rights afforded to defendants under the Missouri rules of civil procedure,’ including specifically the right to a trial by jury and the right to ‘meaningfully assert its position.’ The court reasoned that permitting a post-intervention judgment to extinguish those rights would nullify the 2021 amendments entirely.
The court traced the legislative history. The original 1959 version of § 537.065 allowed injured parties and tortfeasors to agree to limit collection to insurance proceeds, with no notice to insurers. The 2017 amendments added a notification requirement and gave insurers the right to intervene—but left the scope of that intervention ambiguous. Knight by Knight v. Knight, 609 S.W.3d 813 (Mo. App. W.D. 2020) interpreted the 2017 version narrowly, holding that an insurer who intervened after a binding arbitration award had already been entered could not relitigate the merits of the underlying claim.
The 2021 amendments were enacted specifically to overrule Knight and close loopholes that allowed the intervention right to be strategically evaded. Under the current statute, an intervening insurer cannot be bound by any ‘stipulations, scheduling orders, or other orders’ entered before its intervention. The Lyda court extended that principle to post-intervention settlements: just as pre-intervention agreements cannot strip the insurer of trial rights, neither can post-intervention agreements. The $6,140,000 judgment was reversed and the case remanded. The court rejected the respondents’ argument for a narrower scope for § 537.065 despite the legislature’s consideration and reject of language that would have specifically supported Allstate’s position, and the adoption of more general language.
B. The Coverage Appeal Is Dismissed for Lack of Jurisdiction
The court separately addressed Allstate’s appeal from the circuit court’s grant of partial summary judgment finding coverage under the homeowner’s policy. The court concluded that it lacked jurisdiction. Northcott’s three cross-claims—for indemnity, for recovery of defense costs, and for breach of fiduciary duty—all arose from the same operative facts and the same central question and therefore constituted a single ‘judicial unit.’ Because the partial summary judgment resolved only the indemnity crossclaim and left the breach of contract and fiduciary duty claims pending, it was not eligible for certification under Rule 74.01(b). That appeal was dismissed.
III. The Insurer as Real Party in Interest: A Foundational Shift
To understand what Lyda actually means, one must first understand where Missouri law stood before the 2017 and 2021 amendments to § 537.065—and specifically, before these amendments gave insurers the right to intervene and contest the merits of the underlying tort claim.
A. The Traditional Rule: Insurers Were Not Real Parties in Interest
Missouri tort law, consistent with the overwhelming weight of common-law authority, long held that a liability insurer was not a real party in interest in the injured party’s tort action against the insured. The tort lawsuit was between the claimant and the tortfeasor. The insurer sat behind the scenes—it had a contractual obligation to its insured, but that obligation ran to the insured, not to the claimant. The claimant could not sue the insurer directly. The jury did not know whether the defendant was insured. Indeed, informing the jury of the existence of liability insurance was—and in most contexts still is—grounds for a mistrial.
These rules were not arbitrary formalities. They rested on a coherent principle: the insurance contract is a side agreement between the insured and the insurer. The tort claim belongs to the injured party and is asserted against the tortfeasor. The tortfeasor may have contractual rights against the insurer, but those rights—for defense, for indemnity, for good-faith settlement handling—are separate from and collateral to the tort claim itself.
The bar on direct actions against insurers in ordinary tort cases, the prohibition on informing juries of insurance coverage, and the recognition that insurers were not real parties in interest all flowed from the same source: the liability insurer’s legal status was derivative. It occupied no independent position in the tort case. It was not a party. It had no right to be heard.
B. The Statutory Transformation: § 537.065.4 Makes Insurers Functional Real Parties in Interest
Lyda v. Allstate makes unmistakably clear that this traditional understanding no longer reflects the reality of § 537.065.4 litigation in Missouri. When an insurer intervenes under the 2021 version of § 537.065.4, it becomes—functionally, practically, and legally—a real party in interest with independent rights that cannot be waived by the actual parties to the lawsuit.
Consider what the statute now grants to the intervening insurer:
- All rights of a defendant under the Missouri Rules of Civil Procedure
- The right and time to conduct discovery
- The right and time to engage in motion practice
- The right to a trial by jury
- Freedom from any stipulations, scheduling orders, or pre-intervention court orders
- After Lyda: freedom from any post-intervention settlements between the actual parties
The Lyda court itself acknowledged how extraordinary this is. In a footnote, the court noted that Judge Wilson had observed in State ex rel. Country Mutual Insurance Co. v. May, 620 S.W.3d 96, 101-02 (Mo. 2021), that ‘it is highly unusual for an intervenor to be permitted to independently defend a claim which directly implicates the rights of someone else, rather than the intervenor’s own interests.’ The court acknowledged this oddity but enforced it anyway because the statute plainly requires it.
That footnote is the most candid sentence in the opinion. What the 2021 legislature created—and what the Lyda court has now enforced to its logical extreme—is an insurer with all the rights of a defendant and none of the obligations. The insurer is not a party to the tort. It owes no duty to the injured plaintiff. It cannot be held liable for the judgment. It is not bound by its insured’s admissions. But it can contest liability, demand a jury trial, conduct discovery, and block a settlement that both actual parties have agreed to.
In substance if not in formal name, the insurer has become a real party in interest in the tort case. The traditional rule that kept insurers invisible from juries and outside the scope of direct action has been turned inside out in any case touched by § 537.065.
IV. The Insured’s Predicament: A Study in Contractual Inequity
Set aside for a moment the doctrinal analysis of § 537.065 and consider what happened to Mark Northcott—the insured—from a basic contract and fairness standpoint. His situation is not unique. It plays out regularly across Missouri, and it illustrates a profound structural imbalance that the current statutory scheme has created.
A. The Insurer’s Provisional Breach: The Reservation of Rights
When Northcott tendered his defense to Allstate, Allstate had two choices under established Missouri insurance law: accept the defense or decline the defense. If it accepted the defense, it took on all the obligations that come with it—including the duty to investigate, communicate, and handle the claim in good faith. If it declined, it risked losing the right to control the defense and potentially being bound by an adverse judgment.
Missouri law, however, permits a third path unavailable to almost any other contracting party: the reservation of rights. Under a reservation of rights letter, the insurer defends the insured—thus preserving its ability to control the litigation—while simultaneously notifying the insured that it may later disclaim coverage and refuse to pay any resulting judgment. The insurer, in essence, performs its defense obligation provisionally while reserving the right to ultimately breach its indemnity obligation.
In Northcott’s case, Allstate went further still: it refused to defend at all without a reservation of rights and then denied coverage outright. It did so while filing a preemptive declaratory judgment action in federal court to obtain a favorable coverage ruling before any state court could address the issue. The insured was left without a defense in a case where he was admittedly at fault, admittedly intoxicated, and facing a seriously injured plaintiff.
No ordinary contracting party has the ability to say: ‘I may or may not perform my obligations under this contract—I’ll decide after I see how things play out.’ Contract law generally demands that a party either perform or breach. A party who anticipatorily repudiates a contract cannot simultaneously demand the benefits of that contract. Allstate effectively did precisely that.
B. The Declaratory Judgment Action and the Stay: The Insurer’s Procedural Weaponry
Once coverage is disputed, Missouri law gives insurers yet another tool unavailable to ordinary contracting parties: the declaratory judgment action, often filed in a favorable forum and often accompanied by a motion to stay the underlying tort proceedings pending the coverage determination.
Allstate used this tool precisely. Before Northcott and Lyda even had the chance to enter their § 537.065 agreement, Allstate had already filed suit in the Eastern District of Missouri federal court seeking a declaration that it owed nothing under either policy. An insured facing such a lawsuit, while simultaneously being sued by an injured party without a defense, is in an extraordinarily vulnerable position—not through any fault of his own, but because the insurer chose to leverage every procedural advantage available to it.
The declaratory judgment procedure is not inherently improper. Courts have held it is a legitimate mechanism for resolving genuine coverage disputes. But when wielded against an insured who has been stripped of his defense, who faces a mounting judgment from an undefended tort case, and who had no meaningful role in creating the coverage dispute, the declaratory judgment action functions less as a legitimate legal remedy and more as a procedural cudgel.
C. The § 537.065 Agreement: The Insured’s Only Rational Response
The § 537.065 agreement is often framed, particularly by insurers, as a collusive device—a mechanism by which plaintiffs and defendants conspire to manufacture inflated judgments that will be used to extract money from insurers. That framing obscures the reality of why these agreements are entered into.
In the overwhelming majority of § 537.065 cases, the insured enters the agreement because he has been abandoned. He has been left without a defense by the very entity that collected premiums promising to provide one. Faced with the prospect of a default judgment or an uncontested trial that could expose his personal assets to a multimillion-dollar verdict, the insured does the only rational thing available: he reaches an agreement with the injured party that limits his personal exposure in exchange for pursuing the coverage claim that the insurer has denied.
The statute expressly recognizes this by requiring, since the 2017 amendments, that an insurer must first have had the opportunity to defend and declined before a § 537.065 agreement can be entered. The agreement is not collusion. It is self-protection.
D. The Intervention: The Insurer Takes Over the Defense It Refused to Provide
And here is where the statutory scheme reaches its most troubling point. After refusing to defend its insured—after denying coverage, filing a federal declaratory judgment action, and leaving Northcott exposed—Allstate then intervened in the very lawsuit it declined to defend. And upon intervention, it was entitled under § 537.065.4 to all the rights of a defendant: to deny the allegations of the petition, to assert affirmative defenses, to demand a jury trial, and—after Lyda—to block any settlement that Northcott and Lyda reached without Allstate’s consent.
The insurer that refused to defend its insured—that essentially said ‘this claim is not our problem’—then stepped into the litigation to assert defenses on behalf of it’s insured that the insured himself had abandoned. Northcott admitted he was negligent. Allstate denied it. Northcott admitted he was intoxicated. Allstate denied it. Northcott prayed for judgment in Lyda’s favor. Allstate demanded a jury trial to contest liability.
This is not hypothetical equity. This is what happened in the Lyda case, and it is what will happen in every § 537.065 case after this decision. An insurer who has breached—or at minimum conditionally and provisionally refused—its contractual obligations to defend and indemnify its insured retains the right to take over that insured’s defense on terms the insured never agreed to and does not want.
V. Has The Pendulum Has Swung Too Far?
The courts and the legislature have legitimate interests in preventing genuinely collusive arrangements that manufacture inflated, bad-faith judgments designed to be used as weapons against insurers.
But the corrective enacted in 2021—and now fully operationalized by Lyda—has perhaps gone too far. The pendulum has swung past balance and into territory that raises serious questions under basic contract law, and fundamental fairness.
A. The Insurer’s Unique Privilege: Provisional Breach Without Consequences
Contract law—black-letter, first-year contract law—holds that a party who materially breaches a contract cannot simultaneously demand performance from the other party and cannot claim the benefits that performance would have conferred. A contractor who abandons a construction project mid-stream cannot demand the final payment. A tenant who stops paying rent cannot demand that the landlord make repairs. A party who repudiates a contract loses the right to enforce it.
Missouri insurance law has carved out an extraordinary exception to this principle. An insurer who refuses to defend its insured—a refusal that, if wrongful, constitutes a material breach of the insurance policy—can nevertheless intervene in the resulting tort litigation, assert defensive rights on behalf of its insured, block settlements, demand jury trials, and exercise all the prerogatives of a party defendant. The insurer who breaches retains, through statutory grace, all the procedural leverage it would have had if it had performed.
The justification offered for this anomaly is that the insurer’s right to control the defense and participate in liability determinations is necessary to protect its legitimate interest in not being bound by collusive judgments. But this justification conflates two distinct questions: whether the insurer has a right not to be bound by a fraudulent or collusive judgment (a legitimate concern) and whether the insurer has the right to take over the defense after abandoning its insured and its ability to prevent settlement of the claim despite the actual parties wanting to resolve the claim (both far more problematic propositions).
B. The Practical Absurdity: A Defendant Who Admits Liability and a ‘Defendant’ Who Denies It
The Lyda court itself acknowledged the procedural problems its decision will create. In a footnote, the court noted that ‘difficult issues may arise concerning the management of a trial in which two separate parties are defending a single negligence claim asserted against a single defendant—particularly where one of the defending parties concedes liability, while the other contests it.’
These are not hypothetical questions. They will arise in every § 537.065 case on remand after Lyda. The insured tortfeasor—who has admitted liability and who wants the insurer to pay—is now placed in an adversarial posture with his own insurer in the same proceeding in which the injured party is trying to recover. The insured’s rights under his insurance policy, his right to settle his own lawsuit, and his interest in a fair and efficient resolution of the claim against him are all subordinated to the insurer’s right to demand a jury trial.
C. The Insurer’s Unchecked Power and Its Absence of Reciprocal Obligation
Perhaps the most troubling aspect of the post-Lyda landscape is the asymmetry of rights and obligations. The insurer who intervenes under § 537.065.4 acquires the full arsenal of defendant’s rights under the Missouri Rules of Civil Procedure. But what does the insurer give up in exchange for these rights?
Nothing that it did not already owe. The insurer does not, by intervening, waive its coverage defenses. It does not, by exercising defendant’s rights in the tort case, concede that its policy covers the claim. It does not, by demanding a jury trial, agree to pay whatever that jury awards.
Ordinary parties who participate in litigation are bound by its results. They cannot demand the right to contest a claim and then disclaim the obligation to abide by the outcome. The insurer, under § 537.065.4 as interpreted by Lyda, appear poised to do exactly that if all the issues arising out of the common claims and facts are not litigated amongst all the parties.
VI. Practical Implications for Practitioners
For plaintiff’s counsel and defense counsel representing insureds in Missouri tort cases, Lyda v. Allstate creates an immediate and urgent set of strategic considerations.
Settlement timing is now critical. Once an insurer intervenes under § 537.065.4, Lyda makes clear that a bilateral settlement between the plaintiff and the insured cannot terminate the insurer’s right to a jury trial. § 537.065 itself has a number of timing factors that must be considered as well. Practitioners who use a § 537.065 must therefore either resolve the tort claim before intervention occurs or structure any post-intervention resolution with the insurer’s consent—or face reversal.
No § 537.065 or post final judgments § 537.065 agreements. Avoiding a § 537.065. agreement altogether in favor of either a settlement and release, with assignment or a post judgment covenant no to collect are options that must be considered.
The declaratory judgment action remains a parallel battlefield. As the Lyda case illustrates, insurers will file declaratory judgment actions contemporaneously with or prior to the underlying tort litigation. Coordination between the coverage dispute and the tort case—including any effort to a stay the coverage action pending the tort outcome, or vice versa—will be essential. It would appear however, that when a § 537.065 agreement is used and the insurer has the right to intervene that they would no longer be entitled to a declaratory judgment as the right to intervene and participate as a real party interest would prevent the need.
The bad faith claim becomes the insured’s primary leverage. Northcott’s crossclaims for breach of contract and breach of fiduciary duty remain pending after the Lyda decision. These claims—and particularly the bad faith claim—are still among the most powerful tools available to insureds whose carriers have denied coverage and then intervened. An insurer that contests liability in the tort case and loses faces not only the judgment but exposure for any excess verdict and for the consequential damages of having left its insured undefended.
Possibly Preclusion. The jurisdictional holding in the companion appeal also deserves attention. The court’s dismissal of the coverage appeal reinforces the notion that insurance coverage disputes and related bad faith or breach of contract claims arising from the same policy and the same facts constitute a single ‘judicial unit’ for Rule 74.01(b) purposes. Thus, once the insurer has intervened it may be wise for the other parties to assert all viable claims against the insurer or risk having them barred later as compulsory counter claims that should have been raised.
