(1) For legal transactions for the child, the parents need ratification by the family court in the cases in which under section 1821 and under section 1822 nos. 1, 3, 5 and 8 to 11 a guardian needs approval.
(2) The same applies to the disclaimer of an inheritance or of a legacy and for the waiver of a compulsory portion. Where the devolution on the child occurs only as the result of the disclaimer of a parent who represents the child alone or jointly with the other parent, the approval is necessary only if the parent was entitled together with the child.
(3) The provisions of sections 1825 and 1828 to 1831 are to be applied accordingly.
