“When there are more parties than one to a deed, it is not essential to the validity of its execution that they should subscribe unico contextu — i.e., it is not necessary for them to subscribe at the same time and place. But where (as was formerly required) two notaries subscribed for a person who could not write, it was necessary that they should subscribe unico contextu at the same time and place, and before the same witnesses.” John Trayner, Trayner’s Latin Maxims 611 (4th ed. 1894).
