The specificity principle was introduced in the Civil code in 1804 to ensure the development of the modern economy. Then, it gained ground and became a fundamental principle of security law. However, at the end of the 20th century, it was violently criticized : it was accused to diffuse rigidity in security law and put a brake on credit. In addition to the principle noxiousness, its theoretical criticism was all the more announcing its decline in French law, because in foreign states the influence of the American security interest, which is not familiar with the principle, was widening. However, the reform preserved, while softened, the principle in French law. The softening of the principle is the mark of a enlightened reform which intuitively returned to the origins of the principle to confer it the flexibility that the original legislator wanted, but which had been choked by an inadequate theoretical conception. This conception has to be renewed now. Only a return to original sources of hypothec specificity principle is able to capture its practical realty in order to lay the foundation stone of an adapted theoretical conception, which push to removing security law from patrimony rights. The specificity principle is not a sign of the archaism of real and personal security French law, it is, on the contrary, the ferment of his evolution.
