While living together under the same roof, both spouses represent the marital union with regard to the day-to-day needs of the family.
A spouse may represent the marital union with regard to the other needs of the family only if:
authorised so to do by the other spouse or by court order;
the interests of the marital union brook no delay and the other spouse is unable to consent due to illness, absence or other similar reasons.
Each spouse is personally liable for his or her own actions and, to the extent that these do not exceed his or her powers of representation in a manner apparent to third parties, also renders the other spouse jointly and severally liable for such actions.
