Duty of care in English law
In English tort law, an individual may owe a duty of care to another, in order to ensure that they do not suffer any unreasonable harm or loss. If such a duty is found to be breached, a legal liability will be imposed upon the tortfeasor to compensate the victim for any losses they incur.
