Custom of Paris

Coutumes were the customary laws of France.

Developed under feudalism during the Middle Ages and in the early modern period, the coutumes were the laws asserted and enforced by the French kings and their vassals, especially in the lands of the Île-de-France, to the exclusion of Roman law. The area where the French customary law (droit coutumier) was in force was known as the pays de coutume. In the south of France (pays de droit écrit) Roman law remained paramount. The line separating the two areas was generally the river Loire, from Geneva to the mouth of the Charente.

A number of regional coutumes were compiled in the 13th and 14th centuries. The Coutumes de Beauvaisis, compiled by Phillipe de Remy, had a long-lasting influence on French law. There were about 60 such regional coutumes. There were also more than 300 coutumes locales in specific towns and villages. Voltaire said that in France a traveler changed laws as often as he changed horses.

However, by the 16th century the Coutumes of Paris (first published in 1510) had been adopted in all areas except Normandy, Burgundy and Brittany. Further development of customary law had been halted by the late 16th century.

When the Napoleonic code entered into force in 1804 all the coutumes were abolished.

In 1664, under the royal act creating the French East India Company, the Custom of Paris became the only law of the land in New France. In 1866 the Civil Code of Lower Canada was adopted in Lower Canada. The majority of the Code's rules borrowed heavily from the Custom of Paris.
