If you were hurt in a crash in Columbia on or after January 1, 2026, the rules that determine how much you can collect from the drivers who caused your accident changed beneath you before you even knew there were rules to know. South Carolina's Act 42 rewrote two critical pieces of liability law, and insurance adjusters are already using them to reduce what injured drivers receive.

Quick Answer: What Changed for SC Car Accident Claims on January 1, 2026?
Two important things changed this year. First, defendants who are found less than 50% at fault for your crash now pay only their own percentage share of your damages, not the full judgment.
Second, defendants can now ask a jury to assign blame to people and companies who were never sued, including phantom drivers and already-settled parties, potentially shrinking what any single defendant owes you.
Both changes mostly benefit insurance companies, and both apply to crashes that happened on or after January 1, 2026.
What Is Act 42? South Carolina's 2026 Liability Law, Explained
South Carolina Act 42, also known as H.3430 and titled the Tort Reform and Liquor Liability Act, was signed into law in May 2025 and took effect for causes of action arising on or after January 1, 2026.
The law amended S.C. Code § 15-38-15 and fundamentally changed how fault and financial responsibility are allocated in multi-defendant civil cases, including the car accident claims most Columbia residents are likely to face.
The New 50% Fault Threshold for Joint and Several Liability
Under the old rule, joint and several liability allowed an injured person to collect the full judgment from any defendant who was found even partially at fault, regardless of that defendant's percentage of responsibility.
If Driver A was 10% at fault and Driver B was 90% at fault, and Driver B had no money, the injured plaintiff could potentially collect 100% of the judgment from Driver A.
Act 42 changed that. Under the new rule, a defendant who is found less than 50% at fault pays only their own percentage share. A defendant found 50% or more at fault can still be held jointly and severally liable for the entire judgment.
Nonparties on the Verdict Form: How Defendants Shift Blame to Empty Chairs
The second major change is the nonparty verdict form provision. Under Act 42, defendants can now request that the jury assign fault percentages to people or entities who were not sued, including a driver who fled the scene, a party who settled before trial, or any other nonparty the defendant can plausibly blame. The jury fills in a fault percentage for the nonparty, that percentage reduces what the named defendant owes, and the plaintiff cannot collect that share from anyone.
This is what trial lawyers call the empty chair defense. The defendant points at an absent party, the jury assigns them 20% of the fault, and the defendant's own liability shrinks accordingly. Because the injured plaintiff cannot enforce a judgment against a nonparty, that 20% may simply disappear from the recovery.
Under Act 42, once a lawsuit is filed, defendants have 180 days to disclose their intent to designate nonparties for fault allocation. After that window closes, additional nonparties generally cannot be added. This 180-day deadline has significant strategic implications for how cases are built and litigated.
What Didn't Change: Comparative Negligence and the 51% Bar
South Carolina's modified comparative negligence rule is unchanged by Act 42. An injured plaintiff can still recover compensation as long as their own fault does not exceed 50%. If a jury finds the plaintiff 51% or more at fault, they recover nothing. If the plaintiff is 30% at fault, their recovery is reduced by 30% but not eliminated. This framework remains the governing rule for plaintiff fault, and it is entirely separate from the new defendant fault-allocation changes.
The Exceptions: Reckless, Intentional, and DUI-Related Conduct
Act 42 preserves joint and several liability for defendants whose conduct was willful, wanton, reckless, or intentional, and for DUI-related conduct. A drunk driver who injures someone in Columbia is still fully jointly and severally liable for the full judgment regardless of what percentage of fault a jury assigns to other parties. The same applies to defendants who acted with conscious disregard for others' safety.
These exceptions are significant and are one reason why drunk driving accident claims in South Carolina retain their full enforcement power under the new law.
How Fault Percentages Now Decide What You Actually Collect
Under Act 42, the percentage numbers on a jury verdict form translate directly into dollars collected, and every point matters in a way it simply did not before January 1, 2026.
Fault Math in Dollars: A Multi-Vehicle Example
Imagine a three-car chain reaction crash on I-26 producing $300,000 in total damages. A jury finds Driver A 45% at fault, Driver B 40% at fault, and a nonparty 15% at fault. Under Act 42, Driver A owes $135,000 (45%), Driver B owes $120,000 (40%), and the nonparty's $45,000 share is unenforceable. The injured plaintiff recovers $255,000 instead of $300,000 if both drivers are collectible, and potentially much less if one of them is underinsured.
Under the old law, if either Driver A or Driver B had adequate insurance, the plaintiff could have collected the full $300,000 from a single source. That option is gone when neither defendant reaches the 50% threshold.
Why Every Percentage Point Is Now a Fight
Insurance companies understand this math perfectly. Defense attorneys in post-Act 42 cases will argue aggressively to push their driver below 50% and to maximize the percentage assigned to nonparties.
A defendant at 49% pays only their share. A defendant at 50% pays the whole thing. That one percentage point is worth enormous money, which means fault allocation has become the central battleground in South Carolina car accident litigation.
A Columbia car accident lawyer who understands how to build the liability case and challenge nonparty designations is not optional in the post-Act 42 environment. It is the difference between a complete recovery and a significant shortfall.
What the New Rules Look Like on Columbia's Roads
The abstract mechanics of Act 42 become concrete when applied to the specific crashes that happen regularly in Columbia and on the roads surrounding it.
Chain-Reaction Pileups on I-26
Interstate 26 is one of Columbia's primary freight and commuter corridors, and multi-vehicle pileups there involve exactly the kind of complex fault distribution Act 42 was designed to complicate. In a five-car chain reaction, the initiating driver, the driver in the middle who both contributed to and suffered from the pileup, and any other participants all become fault allocation targets.
Defense attorneys will use nonparty designation aggressively in these crashes to spread responsibility across as many parties as possible, driving each individual defendant below the 50% threshold and reducing their joint liability exposure. Preserving evidence from these crashes, including EDR data, surveillance footage, and witness accounts from multiple vehicles, is critical to building a fault case that resists this strategy.
Disputed Lane Changes and Phantom Drivers on I-77
I-77 corridor crashes involving disputed lane changes are prime territory for the empty chair defense. When a driver swerved to avoid another vehicle that fled the scene, the defense will designate that phantom driver as a nonparty and argue for a substantial fault allocation to the absent party.
The injured plaintiff has no recourse against the phantom driver and no way to collect that share. Aggressive investigation, including traffic camera review, toll records, and witness canvassing, is sometimes the only way to identify and pursue the fleeing driver before the nonparty designation window closes.
Intersection Crashes on Two Notch Road
Intersection crashes on busy arterials like Two Notch Road frequently involve disputes about signal timing, right of way, and whether either driver was distracted. When a third vehicle contributed to the conditions of the crash, Act 42 gives the named defendants a mechanism to share the blame.
The 180-day nonparty disclosure window means that defendants will move quickly to identify and designate potential nonparties, and plaintiffs need to be equally fast in gathering the evidence that either ties those nonparties to the case appropriately or contests their designation.
Head-On, Drunk-Driver, and Commercial Vehicle Crashes Under Act 42
Head-on collision cases where one driver clearly crossed the center line present a cleaner fault picture, but Act 42's nonparty provisions still allow defendants to argue that road conditions, a third vehicle, or another factor contributed.
Drunk driving crashes retain full joint and several liability under Act 42's exception for DUI-related conduct, which is one of the most important protections remaining for seriously injured plaintiffs.
Truck accident claims involving commercial carriers present multi-defendant scenarios where the driver, the carrier, and potentially other parties all face fault allocation, and the stakes of each percentage point are magnified by the severity of injuries these crashes typically produce.
Deadlines and Insurance Implications Under the 2026 Law
Act 42 applies to causes of action arising on or after January 1, 2026. Your crash date determines whether the old or new rules govern your case. If your accident happened on December 31, 2025, the pre-Act 42 joint and several liability rules apply to your entire case. If your accident happened on January 1, 2026 or later, Act 42's new framework governs.
This is a bright-line rule, and it means that crash date documentation is among the first things that must be established and preserved in any post-2025 claim.
Statute of Limitations, Government Claims, and the 180-Day Nonparty Window
South Carolina's general statute of limitations for car accident personal injury claims is three years from the date of the crash. Claims against government entities, such as accidents involving government vehicles or caused by dangerous road conditions on public property, carry shorter notice deadlines that can be as brief as 180 days. For wrongful death claims, the wrongful death statute of limitations is also three years from the date of death.
Once a lawsuit is filed under Act 42, the 180-day nonparty disclosure window begins running. Defendants must identify the nonparties they intend to designate for fault allocation within that window. This creates an early pressure point in litigation that makes the pre-suit investigation even more important, because understanding who the potential nonparties are before filing helps shape the litigation strategy from the start.
Why Your Own UM/UIM Coverage Matters More Than Ever
Act 42's changes to joint and several liability make gaps in collectible insurance more likely. When defendants are below the 50% threshold and pay only their percentage share, and when nonparty designations remove portions of the damages from the collectible pool, uninsured and underinsured motorist coverage becomes the backstop that keeps victims from absorbing those losses personally.
UM/UIM coverage on your own policy can fill the gap left by defendants who are underinsured, by nonparty fault allocations that cannot be collected from anyone, and by phantom drivers who cannot be identified. Reviewing your own coverage and understanding how it interacts with the new liability framework is an important part of post-Act 42 claim planning.
Why Acting Quickly Matters More Under the New Rules
Act 42 made fault percentage the central contest in Columbia car accident litigation. Winning that contest requires evidence, and the most powerful evidence in a fault dispute, dashboard camera footage, traffic camera recordings, electronic data from vehicle EDR systems, skid mark and physical evidence documentation, and contemporaneous witness accounts, disappears within days or weeks of a crash.
Once defense counsel files a lawsuit and the nonparty designation window opens, they will be aggressively investigating fault allocation. Plaintiffs who have not already gathered and preserved their evidence are at a significant disadvantage.

Frequently Asked Questions About South Carolina's 2026 Liability Changes
What is South Carolina Act 42?
Act 42, also known as H.3430, is a South Carolina tort reform law signed in May 2025 that took effect January 1, 2026. It amended S.C. Code § 15-38-15 to limit joint and several liability for defendants found less than 50% at fault and to allow fault allocation to nonparties on jury verdict forms.
Does the new liability law apply to my accident?
Act 42 applies to causes of action arising on or after January 1, 2026. If your crash occurred before that date, the prior joint and several liability rules apply. If your crash occurred on or after January 1, 2026, Act 42 governs.
Can I still recover compensation if I was partly at fault?
Yes. South Carolina's modified comparative negligence rule is unchanged. You can recover compensation as long as your fault does not exceed 50%. Your recovery is reduced by your percentage of fault but not eliminated.
What is a nonparty on the verdict form, and why does it reduce my payout?
A nonparty is a person or entity the defendant asks the jury to assign fault to even though they were never sued. The jury assigns them a fault percentage, the named defendant's liability is reduced by that amount, and the plaintiff cannot collect that share from anyone. The result is a gap in recoverable damages.
How long do I have to file a car accident lawsuit in Columbia?
The general statute of limitations for personal injury claims in South Carolina is three years from the date of the crash. Claims against government entities may have shorter notice requirements. Wrongful death claims carry a three-year deadline from the date of death.
Does the 50% rule apply to drunk drivers?
No. Act 42 preserves joint and several liability for defendants whose conduct involved DUI, willful, wanton, reckless, or intentional misconduct. A drunk driver remains fully jointly and severally liable regardless of the new fault threshold rules.
