(Mishnah): If two people were riding on an animal or one was riding and one was walking it, if they both claim that they own the entire animal, each one swears that they do not own less than half of it and they then divide it.

If they both agree or there are witnesses, they divide without swearing.

(Gemara - Rav Huna): The Mishnah (in Maseches Kidushin) teaches that if a woman was riding on an animal with two men directing it, if she said, "These are my slaves and this donkey and its load are mine'';

And each man said, "She is my wife and this (other man) is my slave and the donkey and its load are mine'';

She requires a get from both of them and she must free both of them. The two men must free each other and the donkey and its load are divided equally between the three people.
