(1) If the guardian enters into a contract without the required ratification of the family court, the effectiveness of the contract is subject to the subsequent ratification by the family court. The approval and its refusal take effect in relation to the other party only when the guardian notifies the other party of it.
(2) Where the other party requests the guardian to notify it whether the ratification has been granted, the notification of the ratification may occur only before the end of a period of four weeks after the receipt of the request; if it is not given, the ratification is deemed to have been refused.
(3) If the ward has attained full age, ratification by the ward takes the place of ratification by the family court.
