In personal injury cases, you prove a breach of duty by showing someone didn’t act carefully when they should have. It’s like proving a friend broke a promise to watch your bike, and it got stolen because they weren’t paying attention. To prove a breach of duty, lawyers use facts like what a normal, smart person would do in that spot.
This step comes after proving the person had a job to keep you safe, like a driver watching the road. Evidence such as videos, witness stories, or photos helps show they messed up, like texting while driving or leaving a wet floor without a sign. To prove a breach of duty, you connect their slip-up to your hurt so a judge or jury sees it clearly.
What Is a Duty of Care?
Before you can prove a breach, you first have to show that the person responsible owed you a duty of care. A duty of care means someone has a legal responsibility to keep others safe.
Examples of duty of care include:
- Drivers must follow traffic rules and drive safely.
- Store owners must keep their floors clean and safe.
- Doctors must give proper medical care.
- Employers must keep workplaces safe.
What Is a Breach of Duty?
A breach of duty happens when someone fails to act the way a reasonable person would in the same situation. This could mean acting carelessly or not taking steps to prevent harm.
Examples of breach of duty include:
- A driver texting while driving
- A store owner ignoring a spill on the floor
- A doctor not running important tests
- A landlord refusing to fix broken stairs
Evidence Used to Prove a Breach of Duty
To prove a breach, you need clear evidence. Different types of evidence can be used depending on the situation.
Eyewitness Testimony
People who saw what happened can explain:
- What the other person did
- What the conditions were like
- Whether the person acted carelessly
Their statements help support your version of events.
Photos and Videos
Pictures and videos are powerful evidence because they show what happened. These may include:
- Surveillance cameras
- Phone videos
- Dashcam footage
- Photos of the unsafe area or accident scene
Expert Opinions
Sometimes experts are needed to explain what a “reasonable” person or professional should have done. Experts may include:
- Doctors
- Accident reconstruction specialists
- Safety experts
For example, in a medical case, an expert doctor can explain how another doctor failed to follow proper rules.
Documents and Reports
Documents can help show whether someone ignored warnings or failed to do their job properly. These include:
- Police reports
- Medical records
- Maintenance logs
- Safety complaints
Rules and Safety Standards
If the responsible person broke a rule or safety law, this can strongly support your claim. Examples include:
- Traffic laws
- Workplace safety rules
- Hospital guidelines
Showing the Standard of Care
To prove a breach, you must first define what the “standard of care” should have been. This standard depends on the situation:
- Drivers must obey the speed limit and stay alert
- Property owners must fix or warn about dangers
- Doctors must follow accepted medical practices
Proving the Breach Caused the Injury
It’s not enough to show the person was careless. You must also show that their carelessness caused your injury. For example:
- A store failed to clean up a spill
- You slipped on that spill
- The fall led to your injury
Conclusion
- A breach of duty happens when someone does not act as a reasonable person would.
- You must show that the person owed you a duty, then show how they failed to follow it.
- Evidence like videos, witnesses, documents, and expert opinions can prove a breach.
- You must also show that the breach directly caused your injuries.
