Probably one of the most common types of personal injury lawsuits involves a claim of negligence. Negligence describes a situation in which a person acts in a careless (or negligent) manner, which results in someone else getting hurt or property being damaged.
Negligence is doing something, but doing it badly and without the appropriate standard of care. Neglect is where you fail to do anything. So for example, a lawyer could undertake work for you but do so without the proper care and the work would not be effective and cause damage. This would be negligence. You could however asked the lawyer to do something, but the lawyer failed to do anything, which caused damages, which would be neglect.
