How Do UM and UIM Coverage Change Settlement Strategy in Louisiana?
Uninsured and underinsured motorist coverage changes settlement strategy in Louisiana by adding a second source of payment: your own insurance company. Instead of one negotiation with the at-fault driver’s carrier, the claim becomes a sequenced negotiation across two policies. The order of your moves determines how much of each policy you can actually reach.
That sequencing is the strategic core. A claim against the at-fault driver’s insurer is a third-party negotiation with a company that owes you nothing beyond what its insured legally owes. A claim under your own UM or UIM coverage, governed in Louisiana by La. R.S. 22:1295, is a first-party claim under a contract you paid for. The two claims run on different rules, and decisions made in one directly affect what remains available in the other.
Most Louisiana UM and UIM disputes start the same way. The at-fault driver’s policy is too small for the documented damages, and the injured person needs a path to additional coverage without forfeiting it along the way. Getting that path right means knowing what the coverage is, whether it exists on your policies, how Louisiana layers it on top of the liability policy, and what steps preserve the claim before any release is signed.
Sequencing a liability settlement against a UM claim turns on what UM and UIM coverage are under Louisiana law, whether the coverage is required, how to confirm it exists, how the excess-coverage structure works, stacking, the rules that drive settlement value, the step-by-step calculation, comparative fault, settling with the at-fault driver first, what proof forces payment, bad-faith leverage, and the deadlines that govern all of it.
What Are UM and UIM Coverage Under Louisiana Law?
Uninsured motorist (UM) and underinsured motorist (UIM) coverage are a single coverage under Louisiana law, not two separate products. La. R.S. 22:1295 provides that uninsured motorist coverage encompasses underinsured motorist protection. Under the same statute, every Louisiana auto liability policy includes this coverage unless the named insured rejects it in writing on a form prescribed by the Commissioner of Insurance. That written rejection remains valid for the life of the policy.
What Uninsured Motorist Coverage Does
UM coverage responds when the at-fault driver carries no liability insurance at all. Instead of pursuing an individual with no policy behind them, you present the claim to your own carrier under your own policy.
That structure changes who sits across the table. The claim runs against your own insurance company, not against a stranger’s carrier.
What Underinsured Motorist Coverage Does
UIM coverage responds when the at-fault driver has a policy with limits too small for the harm caused. A serious crash can produce medical bills and lost wages that a small liability policy cannot absorb. UIM coverage supplies a second layer of insurance for the shortfall the at-fault driver’s policy leaves behind.
Why the Single-Coverage Structure Matters
You do not buy or claim UM and UIM separately in Louisiana. One policy provision responds whether the at-fault driver carried nothing or carried too little, and the same carrier handles both kinds of claims.
For a reader checking a declarations page, that means one line item to look for rather than two. How the rejection requirement works in practice, and how to verify what a specific policy includes, is addressed later on this page.
Is UM/UIM Coverage Required in Louisiana?
Yes, by default. La. R.S. 22:1295 writes UM coverage into a Louisiana auto liability policy by operation of law unless the named insured rejects it, selects lower limits, or selects economic-only coverage on the form prescribed by the Commissioner of Insurance. That single statutory default drives everything else in this section.
What the Statutory Default Means in Practice
The policyholder never has to ask for the coverage. Silence produces it. Only a signed, documented choice on the prescribed form removes or reduces it.
The practical result is that a Louisiana auto policy can carry a UM/UIM layer even when the policyholder does not remember requesting it or paying a separate premium for it. Whether a particular signed form actually accomplished a rejection or reduction is a separate question, and the section on confirming coverage walks through how to test that paperwork.
Why the Default Matters: Louisiana’s Minimum Limits Are Low
La. R.S. 32:900(B) sets the mandatory minimum liability limits at $15,000 per person and $30,000 per accident for bodily injury, plus $25,000 for property damage. A single surgery or an extended course of treatment can cost more than $15,000. When the at-fault driver bought only the minimum, the distance between the medical bills and the available liability limits is the space a UM/UIM layer fills.
That gap is why this question comes first in any settlement analysis on this page. Before valuing a claim against a minimum-limits policy, find out whether a UM/UIM layer sits above it. The statutory default is the reason that layer exists more often than policyholders expect.
How Do You Confirm Whether Louisiana UM/UIM Coverage Exists?
You confirm UM/UIM coverage by collecting two documents and reading them side by side: the complete auto policy and the executed UM selection form. Both documents get compared against the text of La. R.S. 22:1295, the Louisiana statute that governs UM coverage and its rejection. A carrier’s verbal statement that coverage was rejected starts the document request. It does not end the investigation.
Read the Executed Selection Form, Not Just the Declarations Page
A declarations page marked “UM rejected” does not settle the question on its own. According to the text of La. R.S. 22:1295, the validity of a rejection or reduction depends on a form prescribed by the Commissioner of Insurance, executed with all of its formal requirements satisfied. The same statutory text provides that a form failing those requirements does not eliminate coverage. Instead, per that statute, UM coverage equal to the liability limits results by operation of law.
The verification steps are document work, not argument. Request the executed selection form from the carrier in writing. Compare each blank, initial, and signature against the prescribed format instead of accepting the carrier’s summary of it. Keep the form in the claim file, because the coverage answer for the entire claim turns on what that single document shows.
Check Which Coverage Type the Named Insured Selected
The same form answers a second question: what kind of coverage the named insured chose. La. R.S. 22:1295 describes an option for an insured to select economic-only UM coverage, which under that statute excludes general (non-economic) damages. Reading the selection portion of the form therefore tells you two things at once. It shows whether coverage exists at all, and it shows whether that coverage reaches the full loss or only its economic portion.
Request Every Policy That Could Apply
A complete coverage check does not stop at one policy. As a document-gathering step, request the policy and the UM selection form for the injured person’s own auto policy, for policies issued to relatives in the same household, and for the policy covering the vehicle occupied at the time of the crash. Each policy carries its own selection form. Each form gets the identical review: prescribed format, complete execution, and the coverage type selected.
One timing point matters when pulling older paperwork. The text of La. R.S. 22:1295 states that a written rejection on the prescribed form remains valid for the life of the policy, so the operative form can predate the wreck by years. Request the form that was in effect on the crash date, not just the most recent renewal packet. Which policy pays first, and whether more than one can combine, depends on priority and stacking rules addressed elsewhere on this page. The confirmation task here is narrower: identify every potentially applicable policy and verify, form by form, what its selection document actually shows.
Does Louisiana Treat UIM as Gap Coverage or Excess Coverage?
Louisiana treats UIM as excess coverage. Under La. R.S. 22:1295, a vehicle is underinsured when the injured person’s proven damages exceed the at-fault driver’s liability limits. The statutory trigger compares damages against the available liability coverage. It does not compare one set of policy limits against another.
That damages-based trigger in La. R.S. 22:1295 is why the gap label misdescribes the Louisiana rule. A gap structure would pay only the spread between two sets of policy limits and would pay nothing when those limits matched. Under the trigger La. R.S. 22:1295 sets out, the UIM layer activates whenever damages exceed the available liability coverage, even when both policies carry identical limits on paper.
La. R.S. 22:1295 pairs that trigger with a credit. Under current Louisiana law, the UIM carrier is credited with the at-fault driver’s available liability limits and answers only for damages above that liability layer, capped at the UIM limits the insured purchased. The liability policy pays first, and under La. R.S. 22:1295 the UIM coverage sits above it as an excess layer rather than replacing it.
Sequencing follows from this excess structure. The liability layer is valued first because its available amounts define the credit La. R.S. 22:1295 gives the UIM carrier. The step-by-step calculation section below works through that math number by number.
How Does UM/UIM Stacking Work in Louisiana?
Stacking in Louisiana turns on one statutory provision: La. R.S. 22:1295(1)(c). By its terms, that provision generally prohibits combining multiple UM coverages for the same accident, and it writes in a single exception for an insured hurt while occupying a vehicle they do not own. Everything else in a stacking analysis is reading: the statute itself, the policies, and the selection forms attached to them.
What Does La. R.S. 22:1295(1)(c) Generally Prohibit?
Stacking means adding the limits of two or more UM policies together for one accident. That practice is what the prohibition stated in the lead, drawn from the text of La. R.S. 22:1295(1)(c), addresses.
When the general rule controls, the practical question becomes which single policy applies. Identifying that policy shapes how a claim is valued and which carrier receives the demand. The answer starts with the statutory text itself, not with a carrier’s summary of it.
When Does the Occupied-Vehicle Exception Apply?
The exception sits in the same provision. As the text of La. R.S. 22:1295(1)(c) describes it, one additional UM policy can stack when the injured insured occupied a vehicle they did not own, and the occupied vehicle’s UM coverage sits primary under that exception.
A passenger hurt in a friend’s car is the situation that statutory wording contemplates. Anyone weighing that scenario should match their facts against the provision’s language rather than assume every household policy joins the claim. The wording, not the household’s policy count, decides what fits.
How Do Waivers and Policy Priority Complicate Stacking?
Stacking disputes rarely turn on the statute alone. In Cutsinger v. Redfern, 2008-2607 (La. 5/22/09), 12 So. 3d 354, the Louisiana Supreme Court addressed how UM waivers and policy priority interact with stacking claims.
That decision makes stacking a document problem before it is a math problem. Confirming what stacks means reading every potentially applicable policy and the selection forms attached to each one. Those documents then get matched against the statutory text and the case law to determine whether the occupied-vehicle language in La. R.S. 22:1295(1)(c) fits the facts and which policy sits primary.
Which Louisiana Rules Most Affect UM/UIM Settlement Value?
Two Louisiana rules move UM/UIM settlement numbers before anyone debates medical bills. The first is the No Pay, No Play bar. The second is the civil jury trial threshold.
One can remove a large piece of a claim before negotiation starts. The other determines whether a judge or a jury would resolve the dispute at trial, and that answer is built into every offer a carrier makes.
No Pay, No Play Under La. R.S. 32:866
La. R.S. 32:866 provides that an uninsured driver cannot collect the first $100,000 of bodily injury damages or the first $100,000 of property damage from the at-fault driver’s insurer, and the bar applies regardless of fault. A driver who carried no insurance can be blameless in the wreck and still lose the first $100,000 in each category.
That changes the settlement math from the first conversation. An adjuster who confirms the claimant was uninsured subtracts the statutory amount before discussing anything else. Proof that the claimant carried valid coverage on the date of the wreck takes the bar off the table, which makes documenting coverage status early a core valuation task.
The $10,000 Civil Jury Trial Threshold
La. C.C.P. art. 1732 sets Louisiana’s civil jury trial threshold at $10,000. That figure shapes whether a UM/UIM dispute is tried to a judge or to a jury, and it shapes settlement posture as a direct result.
The carrier evaluates every claim against the likely outcome if negotiation fails. Whether a judge or a jury would decide that outcome is part of how the carrier sets its number. It is also part of how a claimant’s attorney measures whether the current offer matches what a factfinder would award. A demand that ignores who would actually try the case is a demand built on the wrong assumptions.
Coverage credits, comparative fault percentages, and stacking rules also shift UM/UIM value. This page takes up each of those in its own section.
How Do You Calculate a UM/UIM Settlement in Louisiana Step by Step?
Under La. R.S. 22:1295, a Louisiana UM/UIM settlement is calculated in three steps: value the total damages, apply the credit for the amount recovered from the at-fault driver’s liability coverage, then cap the result at the purchased UM limits. Each step changes the number the UM carrier owes. Get the order wrong and the demand letter starts from the wrong figure.
-
Value the Total Damages
The calculation starts with the full value of the claim, not anyone’s policy limits. That figure is built from documentation of what the wreck cost the insured, supported by records the carrier can verify. The damages number is the input everything else gets subtracted from. An undervalued claim at this stage shrinks every step that follows.
-
Apply the Liability-Limits Credit
The second step subtracts the credit for the at-fault driver’s available liability coverage. Under La. R.S. 22:1295 as interpreted by the Louisiana Supreme Court in Cutsinger v. Redfern, 2008-2607 (La. 5/22/09), 12 So. 3d 945, the UM carrier is credited with the tortfeasor’s full liability limits even when the insured compromises with the at-fault driver for less than those limits. Settling the liability claim at a discount does not shrink the credit, which is one reason the liability limits and the release language must be documented carefully before any UM demand is valued.
The arithmetic in this step therefore depends on the liability limits themselves. The available liability coverage, as documented in the settlement and release, sets the credit subtracted before the UM carrier’s share is calculated.
-
Cap the Result at Your UM Limits
After the credit, La. R.S. 22:1295 caps what the UM carrier pays at the UM limits the insured purchased. Whatever damages remain after Step 2, the purchased UM limits set the ceiling on this layer of the claim. The cited statute makes the purchased limits the outer boundary of what this coverage owes.
Putting the Three Steps Together
The working formula reads: total damages, minus the credit for the available liability limits, capped at the purchased UM limits. Run those numbers before any demand goes out, because the carrier will run them too. Comparative fault can adjust the damages figure before this math begins, and that rule is covered in its own section of this page.
How Does Comparative Fault Change a Louisiana UM/UIM Settlement?
Two statutes the packet cites answer this question together. La. C.C. art. 2323 reduces a claimant’s damages in proportion to their assigned fault when that fault is 50% or less. For causes of action arising on or after January 1, 2026, the same article bars a claimant assigned 51% or more of the fault from collecting anything. La. R.S. 22:1295 measures UM/UIM coverage by what the insured is “legally entitled to recover” from the uninsured or underinsured driver. Under the combined text of those two provisions, the fault percentage assigned to you adjusts the UM/UIM figure before any other settlement mechanic applies.
Louisiana’s Modified Comparative Fault Rule
The rule in this subsection comes from one source: the text of La. C.C. art. 2323. Per that article, Louisiana applies a modified comparative fault system to causes of action arising on or after January 1, 2026. The article’s text reduces a claimant’s damages in proportion to their assigned fault percentage when that percentage is 50% or less. The same text bars a claimant assigned 51% or more of the fault from collecting anything.
The arithmetic below is what the article’s text produces when applied, not a separate conclusion. Applied to a claimant with $100,000 in proven damages who is assigned 20% of the fault, the article yields a collectible claim of $80,000. Applied to that same claimant at 55% fault on a post-2026 cause of action, the article yields zero. The coverage measure in La. R.S. 22:1295, discussed next, carries that statutory arithmetic into the UM/UIM claim.
Why Fault Percentages Reach the UM/UIM Claim
The text of La. R.S. 22:1295 measures UM/UIM coverage by what the insured is “legally entitled to recover” from the uninsured or underinsured driver. That statutory phrase is the bridge between the two provisions. The text of La. C.C. art. 2323 sets what a claimant can collect from the at-fault driver according to the claimant’s fault percentage. The coverage measure in La. R.S. 22:1295 then carries that same statutory reduction into the claim against your own UM/UIM carrier.
This statutory pairing explains why fault allocation gets contested inside a UM/UIM claim even though the carrier is your own insurer. Under the two statutes read together, every fault point the adjuster assigns to you shrinks the amount the coverage measures. Fault allocation is not a fixed fact in a UM/UIM claim; it is a negotiated variable that the documentary record can move.
How Fault Disputes Shape Settlement Posture
The text of La. C.C. art. 2323 converts each fault point into a proportional reduction. Under the coverage measure in La. R.S. 22:1295, evidence pinning fault on the uninsured or underinsured driver therefore carries direct settlement value. Police reports, witness statements, scene photographs, and vehicle damage patterns all bear on the percentage a carrier can credibly assign to you. A claimant who holds their assigned fault near zero protects the full damages figure before any other part of the claim is negotiated.
Can You Settle With the At-Fault Driver and Still Make a UM/UIM Claim in Louisiana?
Yes, when two protective steps happen before anyone signs. The UM carrier receives written notice of the proposed liability settlement, and the release is drafted to reserve the UM/UIM claim. Both precautions exist for the same practical reason: the UM claim runs against your own insurer, and that insurer expects to know about any deal with the at-fault driver before it closes.
Why the UM Carrier Gets Written Notice Before You Sign
A UM adjuster who learns about a finished liability settlement after the fact has a ready argument: the carrier was cut out of a deal it had an interest in. The adjuster points to the policy’s consent-to-settle language and frames the unapproved settlement as prejudice to the carrier. The insured then spends the UM claim defending the settlement instead of proving damages.
Attorneys who handle UM claims treat notice as routine. They send the carrier written notice of any proposed liability settlement and the offered amount, then wait for the carrier’s consent or written response before anything is signed. One letter, sent before the deal closes, keeps the prejudice argument out of the claim file entirely.
How Release Language Can Sweep In the UM Claim
The second precaution is the release itself. UM adjusters read release documents closely, and a catch-all phrase such as “all insurers” or “all parties” gives the adjuster a signed document that appears to include the adjuster’s own company among the released parties. The insured signed it to collect the at-fault driver’s limits and handed the UM adjuster an objection at the same time.
The drafting practice that avoids this is narrow scope. The release names the at-fault driver and the liability insurer, releases only them, and states in plain terms that the insured reserves all claims under their own UM/UIM coverage. A release drafted that way closes the liability settlement without giving the UM adjuster anything to point at.
A Sequence That Preserves Both Claims
The order of operations is simple once stated. First, send the UM carrier written notice of the proposed liability settlement and the offered amount. Second, obtain the carrier’s consent or written response before signing anything. Third, sign a release limited to the at-fault driver and the liability insurer, with an express reservation of UM/UIM rights.
With the liability layer closed correctly through those three steps, attention turns to the UM claim itself, which the next section takes up.
What Proof Makes a Louisiana UM/UIM Insurer Pay or Tender?
La. R.S. 22:1295, Louisiana’s uninsured motorist statute, answers this question in two parts. According to that statute, satisfactory proof of loss means showing four things: the claimant was insured, the other driver was uninsured or underinsured, that driver was at fault, and the extent of damages. According to that same statute, once liability and the undisputed portion of damages are reasonably established, the UM insurer makes an unconditional tender of the undisputed amount. Everything below describes the documents that supply each showing and how a complete demand package shapes negotiation.
The Four Elements of Satisfactory Proof of Loss
Each element corresponds to documents the insured controls or can obtain. A UM demand package that covers all four gives the adjuster nothing to call unproven.
- Insured status. The declarations page and the policy itself show that UM coverage applies to the claimant for this collision.
- Uninsured or underinsured status. An affidavit of no coverage, or the at-fault driver’s liability declarations showing limits below the damages, fills this gap.
- Fault of the other driver. The crash report, witness statements, scene photographs, and any citation issued document who caused the wreck.
- Extent of damages. Medical records, itemized bills, diagnostic imaging, treating-physician narratives, and wage documentation quantify the loss.
A demand letter that attaches documentation on all four points starts the carrier’s evaluation in a way a bare notice of claim does not. A gap in any single element gives the adjuster a defensible reason to delay.
What an Unconditional Tender Means in Practice
Unconditional means exactly what it sounds like. The payment arrives without a release, a dismissal, or any other concession attached, and the insured keeps it however the rest of the claim resolves. The amount reflects the portion of the claim the carrier’s own evaluation does not dispute.
The tender works as a floor, not a ceiling. The insured deposits the payment and keeps negotiating or litigating the disputed remainder. A carrier that contests the value of future treatment, for example, still tenders the portion of the claim it does not contest.
Using the Proof Standard in Settlement Strategy
The four elements give the insured a checklist for building leverage before any demand goes out. A complete package on day one shapes how the adjuster values the file. Every later excuse for delay traces back to a document the insured could have supplied earlier.
What happens when a carrier receives satisfactory proof of loss and still refuses to pay or tender is covered in the bad-faith discussion below.
How Do Louisiana Bad-Faith Rules Change UM/UIM Settlement Leverage?
Louisiana’s bad-faith penalty law gives a UM/UIM claimant a kind of negotiating leverage that a claim against the at-fault driver’s carrier does not carry. Under the revised La. R.S. 22:1892, which absorbed the duty of good faith and fair dealing formerly stated in La. R.S. 22:1973 after that statute’s repeal effective July 1, 2024, the UM/UIM insurer owes first-party duties of good faith and fair dealing to its own insured. That first-party relationship is what makes bad-faith leverage available against your own carrier and unavailable against a tortfeasor’s carrier.
The practical effect shows up at the negotiating table. A first-party carrier is not just weighing the value of the claim. It is also weighing its own statutory exposure for how it handles the claim.
What Does La. R.S. 22:1892 Put at Stake for the Carrier?
La. R.S. 22:1892 attaches a price to a failure to pay within 30 days of satisfactory proof of loss when that failure is arbitrary, capricious, or without probable cause. The statute sets that price at a 50% penalty on the amount due plus attorney fees.
In a negotiation, that text turns delay into a cost the carrier carries itself. A carrier that sits on a documented claim is no longer just postponing payment. It is accumulating exposure of its own.
What Happened to La. R.S. 22:1973?
La. R.S. 22:1973, which formerly imposed a separate duty of good faith and fair dealing and authorized penalties of up to two times the damages sustained or $5,000, whichever was greater, was repealed effective July 1, 2024. The duty of good faith and fair dealing, the prohibited claim-handling practices, and the penalty framework now appear in the revised La. R.S. 22:1892. The old two-times-damages remedy is not current law; for claims governed by the revised statute, the penalty exposure is the framework La. R.S. 22:1892 sets out.
A claimant’s attorney confirms which framework governs the date of loss, because the former statute may still apply to pre-repeal conduct while the revised La. R.S. 22:1892 governs later claims. Either way, the statute prices the carrier’s conduct, telling the carrier that how it handles the claim matters, not just what the claim is worth.
How Does Penalty Exposure Shape Settlement Posture?
Documentation drives this leverage. A complete, organized, date-stamped demand package is what a claimant’s attorney points to when raising statutory penalty exposure with a first-party carrier. Delay then reads as a tactic with a price tag, not a free negotiating move.
This is why UM/UIM negotiations often move differently than liability negotiations. A demand documented and date-stamped to put La. R.S. 22:1892 in play converts the carrier’s delay into measurable statutory exposure.
What Deadlines and Notice Rules Apply to Louisiana UM/UIM Claims?
Three rules control the deadline picture in a Louisiana UM/UIM claim. One sets the period for suing your own carrier. One sets the period for the underlying tort claim. The third connects them through interruption. Each has its own citation and its own start date, and which defendants remain available at filing time depends on tracking all three together.
How Long Do You Have to Sue the UM/UIM Carrier?
An action against your own UM/UIM carrier prescribes two years from the date of the accident under La. R.S. 9:5629. The period runs from the wreck itself, not from the day the liability claim resolves.
That start date matters in practice. Liability negotiations and ongoing medical treatment consume months. A claimant who waits for the liability claim to wrap up before evaluating the UM layer can spend most of that window without noticing it.
What Deadline Applies to the Underlying Tort Claim?
The accident date controls. The underlying tort claim carries a two-year liberative prescription under La. C.C. art. 3493.1 for accidents occurring on or after July 1, 2024. For earlier accidents, a one-year period applies under La. C.C. art. 3492.
Older cases therefore run a shorter clock against the driver than against the carrier. Newer cases run both clocks at the same length, which removes one trap but not the need to calendar each defendant separately.
Can Suing the At-Fault Driver Preserve the UM Claim?
Yes. Under La. C.C. art. 1799 and La. C.C. art. 3503, timely suit against one solidary obligor interrupts prescription against the others, including the UM carrier. Suing the at-fault driver on time is the classic example.
Interruption is a backstop, not a plan. Filing against the carrier within its own period avoids any dispute over whether interruption applies to a particular defendant. Notice obligations tied to settling with the at-fault driver’s insurer are a separate question, addressed in the section on settling the liability claim while preserving the UM claim.
