Gittin 64 - Rosh Chodesh Av - July 19, 1 Av

Today's daf is sponsored by Marcia Baum in loving memory of Sam Baum, Chaim Simcha haLevi ben Aharon haLevi v'Liba on his 20th yahrzeit. "My dad was a larger-than-life individual who was steadfast in his love for family, Israel and yahadut. Stories of his escapades resound even twenty years after his petirah. He is sorely missed by those of us who knew and loved him!" Can a messenger sent by the husband to deliver to a get to his wife also function as a messenger to accept the get for his wife? If the husband gave a get to a middleman and the middleman claims he was given the get to accept on behalf of the wife and the husband claims he gave it to him to hold for him but not to accept it, who is believed? Would the same laws regarding monetary issues and middlemen apply or is this case different? Can the father or the daughter accept the get in the case of a betrothed na'ara (in between stage between child and adult)?
