1,801. Specifying That All Ten Must Sign

Hilchos Geirushin 9:27

If a man tells ten people to write, sign and deliver a get to his wife, one of them should write it, two should sign it and one should deliver it; it is acceptable for one of them to write it, serve as one of the witnesses who signs it, and then as the agent who delivers it. If he specified that all of them should sign it, then they all must sign. If he counted some or all of them and told them to sign it, it’s the same as telling them all to sign it. The first two to sign it do so as witnesses, while the rest do so to fulfill the man’s condition. Therefore, if the extra people are invalid as witnesses, or if one of them signed it on the day the get was written and the rest signed it even several days later, the get remains valid. If one of the people died before signing it, the get is invalid. If one of the first to sign it wasn’t valid as a witness, the get is invalid as a precaution against invalid witnesses signing other types of legal documents in addition to other witnesses. The only reason the Sages permitted such a thing in the case of a get signed by many is because the witnesses to the get’s delivery are the main witnesses.

Hilchos Geirushin 9:28

The Sages enacted the following regarding one who instructs many others to write, sign or deliver a get to his wife: when it comes to writing, he should say that any one of them may write the get; regarding delivery, he should likewise say that any one of them may deliver it; as far as signing, he should say that any two of them should sign the get and give it to her.
