An adult under guardianship or curatorship may not enter into matrimonial agreements without being assisted in the contract by his or her guardian or curator.
Failing such assistance, the annulment of the agreements may be pursued within the year of the marriage, either by the protected person himself or herself, or by those whose consent was required, or by the guardian or curator.
However, the person in charge of the protective measure may apply to the judge for authorisation to enter into a matrimonial agreement alone, with a view to preserving the interests of the protected person.
