(1) A contract that a spouse concludes without the necessary consent of the other spouse is effective if the spouse ratifies it.
(2) Until the ratification, the third party may revoke the contract. If the third party was aware that the spouse concluding the contract is married, then they may revoke only if the spouse untruthfully claimed that the other spouse had consented; the third party may not revoke even though this case is given if they were aware at conclusion of the contract that the other spouse had not consented.
(3) Where the third party demands that the spouse obtain the required ratification from the other spouse, the latter may declare ratification only to the third party; if the latter had made a declaration to their spouse already prior to the demand, the declaration becomes ineffective. The ratification may be made only within two weeks after receipt of the demand; if it is not made, it is deemed to have been refused. If the family court substitutes the ratification, its order is effective only if the spouse communicates it to the third party within the two-week period; failing this, the ratification is deemed to have been refused.
(4) If ratification is refused, the contract is ineffective.
