How do Texas UIM offsets work?

Quick Answer

• Texas UIM offsets generally credit liability payments against the damages you are legally entitled to recover, not by subtracting them from your UIM policy limit.
• The remaining covered damages are subject to the applicable UIM limit and other valid policy terms.
• Do not settle or sign a release just to try to change an offset. Review the available coverage and any consent requirement first.

Ryan Orsatti Law helps injured people in San Antonio and across Texas review damages, insurance credits and settlement documents. This article focuses on offsets, not a promise of payment.

What is the difference between UM and UIM?

UM means uninsured motorist coverage. UIM means underinsured motorist coverage. They can apply when an at-fault motorist has no applicable liability insurance or not enough to cover the insured’s legally recoverable damages. Coverage must exist, and fault, damages and policy requirements still matter.

Texas insurers must provide UM/UIM coverage unless a named insured rejects it in writing, subject to the statute’s renewal and reinstatement rules. When the responsible vehicle’s owner or operator is unknown, Texas law requires actual physical contact for UM recovery. Do not assume every hit-and-run qualifies.

An offset is a credit against covered damages

An offset is a credit used to account for amounts already paid or otherwise properly credited for the same covered loss. The important distinction is between your legally recoverable damages and the maximum amount your UIM insurer can owe.

How Texas Law Applies Offsets

Texas Insurance Code Sec. 1952.106 addresses amounts recovered or recoverable from the underinsured vehicle’s insurer. In Stracener v. United Services Automobile Association, the Texas Supreme Court held that the statutory credit is subtracted from actual damages, not from the UIM policy limit. The remaining covered amount is then subject to that limit.

Farmers Texas County Mutual Insurance Co. v. Okelberry was decided by the Fourteenth Court of Appeals, not the Texas Supreme Court. It involved which settlement proceeds compensated the insured and therefore counted toward the credit. It does not support subtracting liability payments directly from the UIM limit.

Example: liability payment below the UIM limit

Hypothetical, not a case result or payment estimate. Assume a covered bodily-injury claim with $75,000 in legally recoverable damages, $30,000 paid from the responsible driver’s liability coverage, and an applicable $50,000 UIM limit. Assume no other credits, fault reduction, coverage defense or limit issue.

1. Unpaid covered damages: $75,000 – $30,000 = $45,000.
2. Compare the remainder with the UIM limit: the lesser of $45,000 and $50,000 is $45,000.
3. Potential UIM benefits under these assumptions: $45,000.
4. Combined gross payments: $30,000 + $45,000 = $75,000.

The calculation is not $50,000 – $30,000. Also, $30,000 + $50,000 = $80,000 would exceed this example’s $75,000 damages. These are gross figures before attorney fees, case expenses, liens or other repayment obligations, not a client’s net recovery.

Which Texas authorities control the analysis?

Key cases and what they decide

1. Stracener v. United Services Automobile Association, 777 S.W.2d 378 (Tex. 1989), explains why the statutory liability credit reduces damages rather than UIM limits.
2. Mid-Century Insurance Co. of Texas v. Kidd, 997 S.W.2d 265 (Tex. 1999), upheld a PIP nonduplication clause that prevents payment twice for overlapping damages. It did not approve an automatic reduction of UIM policy limits.
3. Farmers Texas County Mutual Insurance Co. v. Okelberry, 525 S.W.3d 786 (Tex. App.–Houston [14th Dist.] 2017, pet. denied), illustrates why settlement allocation and payment records matter.
4. Allstate Insurance Co. v. Irwin, 627 S.W.3d 263 (Tex. 2021), recognizes a direct declaratory action against the UIM insurer to establish entitlement to benefits. Reporting a claim and establishing a legal duty to pay are different steps.

A simplified UIM calculation

For a covered bodily-injury claim, a useful starting point is:

Potential UIM benefits = the lesser of the applicable UIM limit or the positive remainder of legally recoverable covered damages minus applicable credits. If the remainder is zero or negative, this simplified calculation produces no UIM benefits.

1. Establish fault, causation and legally recoverable damages. A medical-bill total alone is not the entire analysis.
2. Identify liability proceeds recovered or recoverable and any other legally valid credits.
3. Apply the applicable UIM limit to the remaining covered damages.
4. Check coverage defenses, all applicable limits and the policy’s requirements before treating the result as payable.

The formula is not a universal settlement calculator. Bodily-injury and property-damage coverages can have different limits and terms. Do not combine them into one limit or assume the calculated amount is what you will receive.

Navigating Common Scenarios

Scenario 1: more than one liability payment

Liability payments exceeding your UIM limit do not, by themselves, eliminate a UIM claim. The question is what covered damages remain after the applicable credits. In a multi-party case, fault allocation, collectible coverage and which claimant each payment compensated require separate review.

Simplified hypothetical, not a case result. Assume $100,000 in legally recoverable covered damages, liability credits of $20,000 + $15,000 + $25,000 = $60,000, and a $50,000 applicable UIM limit. Assume no other coverage, fault or credit issue.

Remaining damages: $100,000 – $60,000 = $40,000. Potential UIM benefits under those assumptions: min($40,000, $50,000) = $40,000. Combined gross payments: $60,000 + $40,000 = $100,000, before fees, expenses and repayment obligations. The fact that $60,000 exceeds the $50,000 UIM limit does not make the result zero.

Scenario 2: PIP or MedPay payments

Do not assume PIP or MedPay payments are excluded from every UIM calculation just because they came from your own policy. In Kidd, the Texas Supreme Court enforced a PIP nonduplication provision to avoid paying twice for overlapping covered damages. The credit operated against damages before the UIM limit was applied.

PIP and MedPay are different coverages. Review the actual clause, the losses each payment covered and the governing law. A payment for one category of loss is not a reason to subtract the same amount mechanically from the UIM policy limit.

Protect the claim before agreeing to a settlement

1. Document actual losses

Keep records supporting medical treatment, wage loss, future care and other claimed harm. Separate bodily-injury damages from property-damage claims. Document the loss accurately; a larger demand does not create coverage or prove damages.

2. Do not settle below limits just to manipulate a credit

Accepting less than the liability limit does not automatically increase what the UIM insurer owes. Sec. 1952.106 refers to amounts recovered or recoverable. Review any credit for available liability coverage, the release and the UIM policy before agreeing to a settlement. A lower liability settlement can leave an uncompensated gap.

3. Identify other coverage while giving prompt notice

Investigate the driver’s policy and any potentially applicable vehicle-owner, employer or umbrella coverage. Do not delay notifying your UIM insurer until that investigation or liability settlement is complete. Identifying available coverage is different from assuming every policy must first pay its limits before a UIM claim may be reported.

4. Check consent and subrogation provisions

Before signing a release, review any consent-to-settle provision and protect the insurer’s potential subrogation rights, meaning its right to pursue a responsible party after paying benefits. Request written consent where required. Under Hernandez v. Gulf Group Lloyds, a settlement-without-consent defense requires actual prejudice under that holding, but avoid creating the dispute in the first place.

What policy limits do and do not tell you

A UIM limit is a cap on covered benefits, not a guaranteed payment and not a fund automatically reduced by the other driver’s limit. A limit comparison alone does not show what the claim is worth.

The appropriate coverage amount and premium depend on the policy and household. Ask for actual quotes and a coverage explanation rather than assuming an increase is inexpensive. If UIM does not apply, other responsible parties, insurance or collectible assets may still need investigation.

Multiple policies and settlement timing

Multiple vehicles are not the same as multiple applicable policies

Do not multiply a single policy’s UIM limit by the number of covered vehicles. Separately identify every potentially applicable policy and insured status. Whether limits can be combined depends on governing law and valid policy terms, not simply on whether an insurer chooses to allow stacking.

Notify early and review the release before settling

A liability settlement is not a reason to postpone notice of a potential UIM claim. A disputed entitlement to UIM benefits may be established directly against the UIM insurer, as explained in Irwin. A settlement with another insurer does not automatically establish all coverage, fault or damages issues. Coordinate notice, consent, proof and lawsuit deadlines before releasing a responsible party.

Before accepting a UIM calculation

Ask for a written explanation separating covered damages, each asserted credit and the applicable limit. Preserve declarations, endorsements, payment records, releases and loss evidence. A personal injury attorney can review those items with the fault and coverage issues; no review can promise a particular payment.

Questions about Texas UIM offsets

Does liability insurance reduce my UIM policy limit?

Under Stracener, the statutory liability credit reduces actual damages, not the UIM limit. Apply the applicable limit to the remaining covered damages. Coverage, recoverable amounts and other valid credits still need review, so a single subtraction does not establish that payment is owed.

Can UIM pay if the liability payment exceeds my UIM limit?

Potentially. A comparison of the two amounts does not decide the claim. The issue is whether legally recoverable covered damages remain after applicable credits, subject to the UIM limit and policy requirements. The multi-payment example above shows why a larger liability payment does not automatically make UIM benefits zero.

Can PIP affect a UIM calculation?

Yes, an enforceable nonduplication provision can matter when payments cover overlapping damages. Kidd upheld such a PIP provision. That is not the same as mechanically subtracting PIP from the UIM limit. Review the clause, the covered losses and the payment records.

Should I sign the liability release before contacting my UIM insurer?

Report a potential claim promptly and review any consent-to-settle requirement before signing. A release may affect the insurer’s subrogation rights. Do not assume that notifying the UIM insurer can safely wait until after signing a release or that every consent problem automatically defeats coverage.

For a different coverage issue, see what happens when the driver is not listed on the insurance policy.
