1,466. Throwing Kiddushin
Hilchos Ishus 4:21
When a man consecrates a woman through money or a document, he need not put the kiddushin in her hand. If she agrees to have him throw it to her and he does, marriage is effected whether he throws them into her hand, her embrace, her courtyard or her field. If she is standing in his domain, then he must put the kiddushin in her hand or her embrace. If she is standing in a domain that they own jointly and he threw her the kiddushin with her consent but they did not reach her, then there is a doubt as to whether marriage has been effected. Even if she tells him to put the kiddushin down in their jointly-owned property, there is a doubt.
Hilchos Ishus 4:22
Let’s say that a man and a woman are standing in the public domain or in a domain that belongs to neither of them and he throws her kiddushin. If it lands closer to him, marriage is not effected; closer to her, it is. If the kiddushin lands midway between them, or if there is a doubt regarding to whom it was closer and it was lost before reaching her hand, then there is a doubt whether marriage is effected. Being closer to one of them means that that person is able to guard the kiddushin to the exclusion of the other. If either or neither of them can guard the kiddushin, then it is considered midway between them.
