If you’ve been injured because of another’s carelessness, you may have heard your lawyer mention the following term: “breach of duty.”
It’s a key building block in a negligence claim in South Carolina, while often being the pieces that determines whether you are even owed compensation.
These are the four things you generally need to prove in order to win a South Carolina personal injury case:
1. The other party owed you a duty of care
2. Said party breached the duty in this instance
3. The breach was what led to your injury
4. You suffered actual damages
Breach of duty is ultimately a hinge, and a very important one at that. It connects a person’s legal obligation to their real-world conduct. Without it, there isn’t a case, regardless of whether you were seriously hurt or not.
A breach of duty happens when someone doesn’t act in a reasonable and careful manner. It’s a term officially known in courts as the “reasonable person standard.”
It applies whether the negligence involved doing something careless or failing to do something that should have been done.
Here are everyday examples:
• Car accidents: A driver runs a stop sign, follows too closely, or looks at their phone instead of the road.
• Premises liability: A store owner sees a spill and opts not to clean it up or post a warning.
• Medical malpractice: A physician misses a diagnosis that a competent doctor in the same specialty would have been able to see clearly.
• Product liability: A manufacturer sells a product with a defect it either knew about, or should have known about it based on their expertise.
In each case, the question isn’t just “did something bad happen?” It’s “did the defendant fall short of how a reasonably careful person, business, or professional would have behaved?”
Breach of duty is not assumed; it needs to be established using evidence.
This differs from case to case, but here are some potential examples:
• Police or incident reports
• Photos or surveillance footage
• Witness statements
• Medical records and expert opinions (especially in malpractice cases)
• Maintenance logs, safety records, or company policies
When there is stronger and specific evidence, it’s easier to show that the at-fault party’s conduct fell below the accepted standard of care.
South Carolina follows a modified comparative negligence rule. If you’re found partly at fault for your own injury, your compensation can be reduced by your percentage of fault, and if you’re found more than 50% responsible, you may be barred from recovering anything at all. That makes a clear, well-documented breach of duty especially important: it shifts the focus of the case onto the other party’s conduct, not yours.
Keep in mind that South Carolina generally gives injured people three years from the date of the injury to file a personal injury lawsuit, so timing is also key.
Proving breach of duty takes more than common sense. It also needs the right evidence, presented the right way. If you’ve been injured, Joseph Kaiser, Attorney at Law LLC, can review what happened and help gather the proof you require.
