Canon 1105. §1 For a marriage by proxy to be valid, it is required:

1° that there be a special mandate to contract with a specific person;

2° that the proxy be designated by the mandator and personally discharge this function;

§2 For the mandate to be valid, it is to be signed by the mandator, and also by the parish priest or local Ordinary of the place in which the mandate is given or by a priest delegated by either of them or by at least two witnesses, or it is to be drawn up in a document which is authentic according to the civil law.

§3 If the mandator cannot write, this is to be recorded in the mandate and another witness added who is also to sign the document; otherwise, the mandate is invalid.

§4 If the mandator revokes the mandate, or becomes insane, before the proxy contracts in his or her name, the marriage is invalid, even though the proxy or the other contracting party is unaware of the fact.

§1. Ad matrimonium per procuratorem valide ineundum requiritur:

1° ut adsit mandatum speciale ad contrahendum cum certa persona;

2° ut procurator ab ipso mandante designetur, et munere suo per se ipse fungatur.

§2. Mandatum, ut valeat, subscribendum est a mandante et praeterea a parocho vel Ordinario loci in quo mandatum datur, aut a sacerdote ab alterutro delegato, aut a duobus saltem testibus; aut confici debet per documentum ad normam iuris civilis authenticum.

§3. Si mandans scribere nequeat, id in ipso mandato adnotetur et alius testis addatur qui scripturam ipse quoque subsignet; secus mandatum irritum est.

§4. Si mandans, antequam procurator eius nomine contrahat, mandatum revocaverit aut in amentiam inciderit, invalidum est matrimonium, licet sive procurator sive altera pars contrahens haec ignoraverit.
