Duty of Care
Duty of care is the first element of a negligence claim. Without a duty, there's no breach to argue about. Who owes a duty to whom is surprisingly specific.
What it means
Duty of care is the legal obligation to behave with the level of caution that a reasonable person would use in the same situation. Drivers owe a duty to other drivers and pedestrians. Doctors owe a duty to their patients. Property owners owe a duty to people lawfully on their property. Who owes a duty to whom depends on the relationship.
How the standard shifts
The standard of care changes with context. A driver owes a duty of ordinary care. A professional — doctor, lawyer, accountant — owes the level of care reasonable in their profession. A common carrier (like an airline or bus company) owes a heightened duty to passengers. These differences matter because 'breach' is measured against the applicable standard.
No duty, no claim
If no duty is owed, there's no negligence claim — even if harm occurred. Classic example: a passerby generally has no legal duty to rescue a drowning stranger. It feels counterintuitive, but without a duty, the failure to act can't be a breach. Exceptions exist for special relationships (employer/employee, innkeeper/guest) and for situations where someone voluntarily begins a rescue.
