Under this regime, in addition to the debts that would form part of it under the legal regime, a fraction of the debts of which the spouses were already burdened when they married, or of which they are burdened by successions and gifts that fall to them during the marriage, are included in the joint liabilities.
The fraction of liabilities that the community must bear is proportional to the fraction of assets that it receives, according to the rules of the preceding article, either in the assets of the spouse on the day of the marriage, or in all the property that is the subject of the succession or liberality.
To establish this proportion, the consistency and value of the assets shall be proved in accordance with article 1402.
