Indiana UM/UIM coverage: required at 25/50 minimum.
Authority: Ind. Code § 27-7-5. Stacking treatment: limited. Personal-injury filing deadline still applies: 2 years from the date of injury.
Why UM/UIM coverage matters in Indiana
When the driver who caused your Indiana crash has no insurance , or has only the state-minimum policy and your injuries blow through it , the only money left on the table is on your own policy. That money comes from UM/UIM coverage.
Indiana is one of about 20 states that mandate UM coverage. Every Indiana-issued auto policy includes it at no less than 25/50 (Ind. Code § 27-7-5). Higher limits are available , and recommended for any driver with significant assets or earnings to protect.
UIM coverage: when the at-fault driver has too little insurance
UIM coverage is the more frequently used cousin of pure UM. In a Indiana catastrophic-injury case, UIM is typically the largest single source of recovery , because the at-fault driver's liability policy is exhausted quickly and the injured party's health insurance recoups through subrogation.
Stacking UM/UIM limits in Indiana
In Indiana, UM stacking rules (limited) determine whether a household with multiple insured vehicles can combine UM limits. Stacking can transform a $50,000 single-vehicle UM policy into a $200,000 four-vehicle policy on the same household , a critical question in serious-injury cases.
Common procedural pitfalls
Two recurring pitfalls in Indiana UM/UIM claims: (1) failing to give the carrier prompt notice (every UM policy includes a notice condition; late notice can excuse coverage), and (2) settling with the at-fault liability carrier without first notifying the UM/UIM carrier (which can extinguish subrogation and trigger a coverage forfeiture).
Hit-and-run claims in Indiana
Hit-and-run cases are a primary use of UM coverage in Indiana. Where the at-fault driver flees and cannot be identified, the injured party's own UM coverage steps in , provided the policy's "phantom vehicle" requirements are met (typically physical contact between the vehicles or independent corroborating evidence).
The UM/UIM claim process in Indiana
A Indiana personal-injury claim moves through five identifiable steps: (1) initial reporting to the at-fault driver's insurer (within 24-72 hours), (2) medical treatment and documentation (ongoing, typically 3-9 months), (3) demand-package preparation and submission once MMI is reached, (4) negotiation and counter-offers (typically 30-90 days), and (5) suit filing if pre-suit negotiation fails. Each step has its own procedural pitfalls , for instance, recorded statements to the carrier in step 1 can lock in damaging admissions that haunt the case in step 4.
Indiana insurance carrier landscape for UM claims
Indiana's auto-insurance market is dominated by a familiar set of carriers , State Farm, GEICO, Progressive, Allstate, Liberty Mutual, USAA, and Farmers , plus regional specialists. Indiana's Department of Insurance publishes complaint ratios and market-share data annually; carriers with high complaint ratios relative to market share are flagged for additional regulatory scrutiny. For plaintiffs, this matters because complaint-ratio data is admissible bias evidence in extreme bad-faith cases.
Evidence that wins Indiana UM/UIM disputes
Evidence preservation matters even more in Indiana than in other jurisdictions because of the state's civil procedure rules around spoliation. The first 30 days after the incident are decisive: medical records, photographs of injuries and the scene, witness contact information, and any video footage (residential doorbell cameras, retail security systems, dashcam) all need to be secured before they are overwritten or discarded. Indiana courts can impose evidentiary sanctions on parties who lose control of relevant evidence after notice of a potential claim.
Real-world Indiana UM/UIM case patterns
A common Indiana scenario involves a slip-and-fall at a chain retailer where the defendant initially denies liability based on the "open and obvious" defense. The plaintiff's case is built through surveillance-video preservation letters (sent within seven days of the fall), photographs of the unsafe condition before it is repaired, witness statements from store employees, and Indiana's premises-liability case law on the storekeeper's duty of care. Cases that look unwinnable based on initial police-report-style summaries often resolve at six- or seven-figure values once a complete record is built.
Mistakes that reduce Indiana UM/UIM recovery
Plaintiffs in Indiana commonly underestimate the procedural complexity of personal-injury litigation. Common oversights include failing to identify all potential defendants (especially in commercial-vehicle cases where the driver, owner, and employer are often different entities), failing to preserve electronic evidence (text messages, GPS data, telematics), and failing to comply with policy-condition deadlines (e.g., examinations under oath for UM claims). Each oversight is recoverable if caught early but irreversible if caught late.
Indiana UM/UIM FAQ
Is UM coverage required in Indiana?
Yes. Indiana mandates UM coverage at a minimum of 25/50 under Ind. Code § 27-7-5.
What is the difference between UM and UIM in Indiana?
UM (uninsured motorist) pays when the at-fault driver has NO insurance. UIM (underinsured motorist) pays when the at-fault driver has SOME insurance but their limits are inadequate to cover your damages. Indiana policies typically bundle the two together, though limits and exclusions can differ.
Can I stack UM coverage in Indiana?
Indiana allows stacking with limitations or offsets. The specific rule (limited) depends on your policy language and recent appellate decisions.
What if the at-fault driver fled the scene?
UM coverage on your own policy applies to hit-and-run / phantom-vehicle scenarios in Indiana, typically subject to physical-contact or independent-corroboration requirements set by your policy.
Do I need to notify my insurer before settling with the at-fault driver?
Yes. Almost every Indiana UM/UIM policy requires written notice and consent before settling with the at-fault liability carrier. Settling without consent can void UM/UIM coverage by extinguishing the carrier\'s subrogation rights.
How long do I have to file a UM/UIM claim in Indiana?
The policy itself sets the notice deadline (often "as soon as practicable" or 30-180 days). The underlying personal-injury SOL is 2 years under Ind. Code § 34-11-2-4, and most courts treat UM claims as contractual , meaning the contractual limitations period in the policy may also apply.
