Each of the spouses has the power to enter alone into contracts which have as their object the maintenance of the household or the education of the children: any debt thus contracted by one obliges the other jointly and severally.
Solidarity does not apply, however, to expenditure which is manifestly excessive, having regard to the lifestyle of the household, the usefulness or uselessness of the transaction, or the good or bad faith of the third party contracting.
Neither does it apply to instalment purchases or loans, unless they have been concluded with the consent of both spouses, unless the latter relate to modest sums necessary for everyday needs and the cumulative amount of these sums, in the case of several loans, is not manifestly excessive having regard to the household’s way of life.
