A minor who is capable of contracting marriage is capable of consenting to all agreements of which that contract is susceptible, and agreements and donations made by him are valid, provided that he was assisted in the contract by the persons whose consent is required for the validity of the marriage.
If matrimonial agreements have been made without such assistance, their annulment may be requested by the minor or by the persons whose consent was required, but only until the expiry of the year following the attainment of majority.
