The scheme of joint ownership operates like the basic separation of property regime during marriage , each manages its assets as it sees fit and each is liable for personal debts. Then, at the moment of the dissolution, we find ourselves in a system close to that of the legal community. Thus, the patrimony of each spouse is compared to the day of marriage and to the day of its dissolution. And if one of the spouses has enriched his patrimony, he will owe to the other half of the increase of his patrimony.
Attention: it must be verified that there is no clause in the marriage contract to exclude professional property from the participation claim. If this is the case, the business spouse retains the full benefit of his activity.
