The Other Driver Offered Policy Limits. Notify Your UM Insurer Before You Sign.
A policy-limits offer usually feels like progress. The at-fault driver’s insurer has agreed to pay everything its policy provides. A release is attached. The adjuster wants a signature so the check can be issued.
That signature can create a second insurance fight.
If the settlement will not fully compensate an injured person and uninsured or underinsured motorist coverage may apply, Florida law gives the UM insurer a chance to protect its rights before the at-fault driver is released. Signing first can breach the insurance policy and create a presumption that the UM carrier was prejudiced. A September 2026 decision from Florida’s Fourth District Court of Appeal shows that coverage may sometimes survive—but only after a difficult, fact-intensive battle that should never have been necessary.
The dangerous moment is when a good offer arrives
Suppose an injured driver has damages far above $10,000. The person who caused the crash carries only $10,000 in bodily-injury liability coverage, so that insurer offers its limit. The injured driver also has $500,000 in UM/UIM coverage.
The $10,000 offer is not the end of the claim. It is the point where two claims intersect. Accepting the liability money may require releasing the at-fault driver. That release can destroy the UM insurer’s potential right to recover from the at-fault driver after paying UM benefits—a right known as subrogation.
Florida’s UM statute therefore creates a process that must occur before the release is finalized. The insured cannot safely treat the liability settlement and the UM claim as two unrelated files.
This is a different question from whether coverage is stacked or non-stacked. Tucker Law’s article on stacked and non-stacked UM coverage in Florida explains how policy structure can affect the amount and source of coverage. The consent-to-settle issue asks whether the insured preserved that coverage while resolving the claim against the other driver.
Progressive v. Heimler: a $10,000 release put $500,000 in UM coverage at risk
The new case began with an April 2022 crash. According to the Fourth District’s opinion in Progressive American Insurance Company v. Heimler, the at-fault driver had $10,000 in liability coverage. The injured insured had a Progressive policy with $500,000 in UM/UIM limits.
The insured entered into a bodily-injury release with the liability insurer for $10,000 without first obtaining Progressive’s permission or a waiver of its subrogation rights. New counsel later recognized the problem. Counsel notified Progressive of the tender, requested a subrogation waiver, and sent the liability insurer a $10,000 trust-account check in an effort to unwind the settlement.
The release was not rescinded. Progressive asserted that settling without consent breached the policy and section 627.727. That issue required a separate trial before the parties could reach negligence, causation, permanency, and damages.
The insured ultimately kept the UM claim alive, but not because the missed step was harmless as a matter of law. The trial court found that the at-fault driver was probably insolvent and that Progressive had not actually lost a valuable collection opportunity. The Fourth District affirmed on September 9, 2026. Its opinion includes the standard notice that it is not final until any timely rehearing motion is resolved.
The practical lesson is not that permission can be skipped. The case confirms the opposite: the insured breached the policy, prejudice was presumed, and the insured had to prove the absence of prejudice. A favorable result came only after litigation into the at-fault driver’s income, vehicles, real estate, bank balance, business assets, household finances, and prior settlement proceeds.
Why the UM insurer gets a voice in the settlement
UM coverage is designed to protect an insured when the legally responsible motorist has no bodily-injury coverage or not enough coverage to satisfy the damages. Tucker Law’s Florida uninsured-driver accident guide explains where UM fits alongside PIP and a claim against the negligent driver.
When a UM insurer pays, it may acquire a right to pursue the at-fault driver or liability insurer for amounts the responsible party should have paid. A full release can extinguish that route. The consent-to-settle procedure gives the UM carrier a choice: allow the settlement and waive subrogation, or preserve subrogation by advancing the amount offered by the liability insurer.
That explains why the paperwork matters even when the at-fault driver appears to have few assets. The insured does not get to make that collectability decision unilaterally and then force the UM insurer to accept it. The statutory process lets the carrier evaluate the potential recovery before the release closes the door.
Florida’s statute creates a sequence, not merely a courtesy notice
Florida Statutes section 627.727(6) applies when an injured person—or a personal representative in a death claim—agrees to settle with a liability insurer and its insured, but the settlement will not fully satisfy the injury or wrongful-death claim and an underinsured-motorist claim remains.
The statute requires written notice of the proposed settlement to every UM insurer providing coverage. It specifies certified or registered mail. After receipt, the UM carrier has 30 days to consider whether to authorize the settlement or retain its subrogation rights.
If the carrier authorizes settlement, the injured person may finalize the release without prejudicing the UM claim. The same is true if the carrier does not respond as required within the 30-day period. If the UM carrier refuses permission because it wants to preserve subrogation, it must pay the injured person the amount of the liability insurer’s written offer within that period. The carrier can later pursue subrogation after the UM claim is resolved.
Section 627.727(6)(c) adds another important detail: the UM carrier generally receives a credit based on the at-fault driver’s liability-policy limits in cases governed by the subsection, even if the liability settlement or the carrier’s advance is less than those full limits. Settling below limits therefore requires analysis beyond the amount of the check being offered.
Notice should identify every possible UM policy
The statute refers to notice to all underinsured-motorist insurers that provide coverage. That wording makes early coverage investigation critical.
The obvious policy is not always the only policy. Depending on the facts and policy language, the analysis may include coverage on the occupied vehicle, a policy issued to the injured person, resident-relative coverage, an employer’s policy, or another policy that follows the insured. A declarations page alone may not answer who qualifies as an insured or which endorsements apply.
Before any release is signed, counsel should have the complete liability tender, proposed release, declarations pages, policies and endorsements, UM selection forms, and enough injury information to determine whether the liability payment will fully satisfy the claim. Tucker Law’s UM coverage analysis discusses why household vehicles and election forms can change the available limits.
A notice sent to one carrier does not necessarily protect a claim under another policy that was never identified. Coverage mapping must come before settlement finality.
A broad release can affect more than subrogation
The title on a document does not control everything it releases. A form labeled “bodily injury release” may discharge the driver, vehicle owner, insurer, employer, or other people and entities. It may include indemnity language, lien provisions, confidentiality terms, or representations about other insurance. A property-damage release can also contain language broad enough to create an injury dispute if it is not read carefully.
The release should be compared with the settlement offer and the intended scope of the agreement. Names, policy limits, claim numbers, reserved claims, lien responsibilities, and payment terms should be checked. If a crash involves a commercial vehicle, borrowed vehicle, rideshare driver, or multiple tortfeasors, releasing one party can have consequences that are not obvious from the adjuster’s cover email.
Florida’s recent named-driver-exclusion guidance illustrates a related point: the vehicle at the scene does not necessarily reveal the complete insurance picture. The policies and endorsements do.
Heimler offers a rescue rule, not a safe shortcut
Florida cases recognize that an unauthorized settlement does not always destroy UM coverage automatically. But the breach creates a rebuttable presumption of prejudice, and the insured bears the burden of showing that the carrier was not prejudiced.
Heimler framed the inquiry in practical terms. A court may ask what a reasonably prudent insurer would have done if proper notice had been given. Would it have approved the liability settlement, or would it have rejected the offer, advanced the money, and pursued the at-fault driver because the expected recovery justified the cost?
Probable insolvency can overcome the presumption because a lost judgment against someone with no realistically collectible assets may have little value. Yet proving that point can be intrusive, expensive, and uncertain. A tortfeasor who looks judgment-proof at first glance may own nonexempt property, receive income, hold business interests, or have access to other assets. Different evidence can produce a different result.
This burden also should not be confused with every other insurance-policy breach. Tucker Law’s review of State Farm v. Curran discusses a different UM policy condition and a different allocation of the prejudice burden. The type of obligation and the governing statute matter.
If the release has already been signed, the timeline becomes evidence
Someone who discovers the problem after signing should not assume the UM claim is automatically lost—and should not assume returning the settlement money automatically fixes it. Heimler itself involved an unsuccessful effort to unwind the release.
The entire sequence should be preserved: the tender letter, release drafts, emails, envelopes, proof of delivery, settlement check, deposit records, communications with each insurer, policy documents, and any attempt to rescind. The at-fault driver’s collectability may also become central. Asset searches, sworn testimony, financial records, vehicle ownership, real-estate interests, business assets, exemptions, and collection costs may affect whether the UM carrier suffered actual prejudice.
Prompt legal review matters because the available options depend on what was signed, whether payment was accepted, who was released, which carriers had notice, and whether a settlement can still be rescinded by agreement. The answer will come from the documents and chronology, not from a generic assurance that “the UM claim is separate.”
A policy-limits check should not cost the rest of the insurance claim
The clean path is straightforward: identify every potentially applicable UM policy, send the statutory notice before executing the release, document each carrier’s receipt, and allow the 30-day process to run unless the carrier provides authorization sooner. The proposed release should then match the permission received.
A serious crash claim can involve multiple layers of liability and first-party coverage. Tucker Law’s Florida car accident practice focuses on finding those layers and protecting them through settlement. Additional resources are available through the Personal Injury Information Center.
If an insurer has offered policy limits—or a release has already been signed—contact Tucker Law before the next step makes the coverage dispute harder. The first settlement should open the door to available compensation, not close the door on the policy that was supposed to cover the rest.
