(1) If the person renouncing is under guardianship, ratification by the family court is required for the renunciation of the inheritance; if they are under parental custody, the same applies. Ratification by the custodianship court is required for a renunciation by the custodian.
(2) The testator may enter into the contract only in person; if they have limited capacity to contract, they do not require the approval of their legal representative. If the testator is incapable of contracting, the contract may be concluded by the legal representative; the ratification of the family court or custodianship court is required to the same extent as specified in subsection (1).
