South Carolina drivers hit by uninsured or underinsured motorists often don’t know how to recover compensation when the at-fault driver can’t pay. In these cases, your own insurer handles the claim and may aim to minimize payouts just like a third-party carrier. This guide explains the difference between UM and UIM coverage and how an uninsured motorist claim South Carolina works in practice.
UM vs. UIM: Understanding Two Different Coverage Types
Most drivers know they have uninsured motorist (UM) coverage, but few realize it actually covers two distinct situations with separate rules and claims processes.
1. Uninsured Motorist (UM) Coverage
UM coverage applies when the at-fault driver has no auto liability insurance at all.
Key points about UM in South Carolina:
- South Carolina’s minimum liability coverage: $25,000 per person for bodily injury
- Many drivers carry no insurance, leaving victims without direct recovery from the at-fault driver
- National statistics: ~10% of U.S. drivers are uninsured; South Carolina may have a higher real exposure due to enforcement gaps
- Your UM policy steps in to cover your injuries up to your policy limits
2. Underinsured Motorist (UIM) Coverage
UIM coverage applies when the at-fault driver does have insurance, but their policy limits are too low to cover your damages.
Consider this example:
- At-fault driver has the SC minimum $25,000 coverage
- Your medical bills and lost wages total $90,000
- Gap in coverage: $65,000
- Your UIM coverage pays the difference, up to your policy’s UIM limits
When SC’s UM and UIM Coverage Kicks In
UM and UIM coverage don’t activate automatically when you’re hit by an uninsured or underinsured driver; specific conditions and order of steps matter.
For a UM claim, the at-fault driver must be confirmed uninsured, or in a hit and run, must have made physical contact and fled. The South Carolina hit and run process follows the UM framework but requires additional police documentation.
For a UIM claim, your own coverage only applies after the at-fault driver’s liability policy is fully exhausted, a step called a “limits tender” that must be formally documented. South Carolina also allows UM/UIM stacking in some cases, letting you combine limits across multiple vehicles or policies to increase total coverage. An attorney can quickly determine whether stacking applies by reviewing your declarations page.
Stacking is more common than most policyholders realize, and the difference it makes to total available coverage can be significant. If you have two vehicles insured under the same policy with $50,000 in UIM limits per vehicle, stacking could give you access to $100,000 in UIM coverage for a single crash. Not all policies allow it, and insurers rarely volunteer the information, which is one of the reasons reviewing your declarations page with an attorney before settling any UM or UIM claim is worthwhile.
Why Your Own Insurer Isn’t Automatically on Your Side
Most policyholders don’t realize this: in a UM or UIM claim, your own insurer is the opposing party. They evaluate and may contest your claim using the same financial incentives that drive third-party carriers to minimize payouts.
Your insurer reviews the claim, medical records, and police reports, and may dispute liability or injury severity. They can hire their own experts, deny claims, make low offers, or invoke policy exclusions.

What Filing a UM Claim in SC Actually Involves
The process starts by notifying your insurer promptly, usually within a few days, as delays can lead to claim denial on procedural grounds. The claim then follows a path similar to a third-party case: medical records, documented losses, proof of the at-fault driver’s lack of coverage, and a demand covering economic and non-economic damages. If the accident involved a drunk driver, punitive damages may add leverage, though UM coverage rarely pays them directly. An attorney can help assess this.

What to Do When Filing an Uninsured Motorist Claim South Carolina
Filing an uninsured motorist claim in South Carolina means navigating a system where your own insurer holds the money and controls the investigation. It does require understanding the rules clearly and building your claim with the same care you would against any third-party carrier.
The three-year statute of limitations under SC Code § 15-3-530 applies to UM and UIM claims, but your insurer’s internal reporting deadlines are typically far shorter. Both deadlines apply simultaneously. Acting quickly after a crash involving an uninsured or underinsured driver is the single most effective way to preserve both your legal options and the quality of your evidence.

Frequently Asked Questions
1. Do I have to sue my own insurance company to get UM benefits in South Carolina?
Not necessarily. Many UM and UIM claims settle without litigation. But if your insurer denies the claim, disputes liability, offers too little, or acts in bad faith, suing your own carrier is allowed. South Carolina’s bad faith law provides remedies when an insurer mishandles a claim.
2. What if I didn’t know the at-fault driver was uninsured until after the crash?
This is common. Confirm the at-fault driver’s insurance via the police report, your insurer’s investigation, or the driver’s carrier. If they’re uninsured, notify your insurer immediately so the claim proceeds under UM coverage, as prompt reporting is required.
3. Can my UM claim be denied if I was partly at fault for the crash?
South Carolina’s modified comparative fault rule applies to UM claims like third-party claims. Recovery is reduced by your fault if 50% or less, but barred entirely at 51% or more. Your insurer evaluates fault just like a third-party carrier, so legal representation before giving statements is crucial.
4. What is the difference between UM limits and UIM limits on my policy?
Some SC policies have equal UM and UIM limits, while others differ; your declarations page shows both. UM is the max your insurer pays if the at-fault driver has no insurance, while UIM covers the gap when their policy is insufficient. Some policies allow stacking across multiple vehicles, increasing total coverage, and reviewing your declarations page with an attorney can quickly reveal hidden benefits.
5. How long does a UM or UIM claim take to resolve in South Carolina?
Simple UM claims with clear liability and documented injuries often resolve in 3 to 6 months. Disputed claims, where fault or injury severity is challenged, can take 1 to 2 years, especially if litigation is needed. UIM claims add time upfront while the at-fault driver’s policy is exhausted, and severe injury cases require longer to calculate full damages before a settlement demand.
Key Takeaways
- South Carolina requires insurers to offer UM and UIM coverage, though written rejection is allowed, leaving some drivers unprotected.
- UIM coverage only applies after the at-fault driver’s liability policy pays its full limits.
- UM/UIM stacking can increase coverage in multi-policy or multi-vehicle situations.
- Your own insurer handles the claim, with the same financial incentives to minimize payouts as a third-party carrier.
- Both the three-year statute of limitations and the insurer’s prompt-notice requirement must be met for a valid claim.
