During the Ancien Régime in France, marriage was indissoluble and only separation was allowed. The Constitution of 1791 declared that marriage was only a civil contract (the principle of the indissolubility was rejected). The law of 1792 abolished separation and allowed to get a divorce, which was easily accessible – even incompatibility of temperament could be a reason for untying a marriage knot. During Robespierre’s rules, liberal law of 1792 was even more liberalized. After the Thermidorian Reaction, conditions of obtaining a divorce were tightened but the law in that matter was still liberal. It was not until the introduction of the Law of 1803, that the number of grounds for a divorce was limited. In 1804, the Law of 1803 became the part of the Code Civil.
