My future spouse and I have an appointment with the notary to sign our marriage contract. Unfortunately, I have just learned that I will not be able to attend due to professional obligations. Is it possible to appoint someone by proxy?

Yes, but under specific conditions. In principle, both spouses must be present before the notary to sign the marriage contract (Article 1394 of the French Civil Code). However, case law allows a spouse to be represented by a third party. The representative must hold a special authentic power of attorney, which must include the full text of the proposed marriage contract (Court of cassation, 1st Civil Chamber, 5 February 1957).
