Dolus is a Latin term for “device or artifice.” In Civil and Roman law it refers to a fraudulent conduct used to deceive some one; fraud or deceit; bad faith. Although there may be dolus without fraud, fraud always includes dolus. Dolus is different from fault. Fault proceeds from an error of the understanding while to constitute Dolus there must be a will or intention to do wrong. It also means intentional aggression or willful injury, caused to another's property.
