(1) Each spouse is entitled to enter into transactions serving to appropriately provide the necessities of life of the family, with effect also for the other spouse. Such transactions entitle and oblige both spouses, unless the circumstances lead to a different conclusion.
(2) One spouse may restrict or exclude the entitlement of the other spouse to enter into transactions with effect for them; if there is no adequate reason for the restriction or exclusion, the family court is to set it aside on application. In relation to third parties, the restriction or exclusion is effective only subject to the stipulations of section 1412.
(3) Subsection (1) does not apply if the spouses live apart.
