South Carolina blocks UM recovery only when fault exceeds 50 percent. Hit-and-run claimants keep their claim alive at the even-split mark and below -- a margin that matters when the insurer's assignment lands near the line.
How the 51-Percent Fault Bar Works in Hit-and-Run UM Claims
Modified comparative fault with a 51-percent bar means your hit-and-run UM claim remains valid as long as your fault stays at or below half. The insurer must demonstrate that you were more responsible than the phantom driver -- or any other contributing factor -- before it can deny the claim. In practice, the insurer applies the same fault-analysis techniques it would use in any liability dispute: reviewing the police report, examining vehicle damage, and questioning your account of the crash. The difference is that in a UM claim, the company on the other side of the table is your own carrier.
Building Evidence to Stay Below the 51-Percent Bar After a Hit and Run
The 51-percent fault bar gives you more room than a 50-percent-bar state, but you still need evidence to hold the line. Document the crash scene thoroughly -- photographs, dashcam footage, and witness statements form the foundation of your fault defense. Pay attention to details that show the phantom driver's conduct: tire marks from aggressive acceleration, debris patterns indicating the other vehicle crossed into your lane, and impact angles that match your account. Your insurer's adjuster will examine these same details with a different objective, so make sure your documentation is complete and internally consistent.
A worked example with South Carolina’s rule applied
Take a hit and run claim with documented losses like these:
| Medical bills | $14,200 |
| Lost wages | $7,800 |
| Other out-of-pocket costs | $1,150 |
| Pain and suffering (3.0× medical) | $42,600 |
| Gross value before fault | $65,750 |
Under South Carolina’s 51% bar, percentages behave like a cliff edge. At 50% fault this claim still pays $32,875; at 51% it pays $0. One percentage point moves $32,875, which is why the fault number in the adjuster’s file is worth arguing about with evidence, not estimates.
Filing a UM Claim After a Hit and Run: What Your Insurer Will Not Tell You
When the at-fault driver flees, your own UM coverage becomes the claim path -- and your insurer becomes the opposing party. The carrier reviews your demand, evaluates your damages, and decides what to pay. It does this while also holding the power to assign fault to you, which directly reduces the payout in South Carolina. This dual role -- both your coverage provider and your adversary -- means you should approach the claim with the same level of preparation you would bring to a dispute with a stranger's insurer. Complete medical records, wage-loss proof, and a well-documented crash narrative are the foundation. An attorney experienced in UM disputes can level the negotiating dynamic.

Questions
South Carolina questions
Does equal fault bar my hit-and-run UM claim in South Carolina?
No. South Carolina uses a 51-percent comparative fault bar, so equal fault -- 50 percent -- does not block your claim. You lose recovery only when your assigned fault exceeds 50 percent. At the even split, you still receive a proportionally reduced payout from your carrier.
How does South Carolina's 51-percent bar differ from a 50-percent bar in a hit-and-run UM claim?
The difference is one percentage point at the threshold. Under a 50-percent bar, reaching exactly half fault eliminates your claim. Under South Carolina's 51-percent standard, you must exceed half. That additional point of margin can be decisive when the insurer's fault assignment lands near the line.
What can I do if my UM insurer assigns me close to 51 percent fault in South Carolina?
Challenge the fault assignment with evidence. Dashcam footage, scene photographs, witness testimony, and the police report all contribute to the fault calculation. If the insurer's assignment relies on assumptions rather than documented facts, raise that during negotiations. Consulting an attorney before accepting the assignment is advisable when the percentage sits near the threshold.
