If a creditor sells a note of indebtedness to his fellow and afterwards
forgives the debt - it is indeed forgiven. Therefore, if one betroths a
woman by giving her a loan document for collection, she may fear that
he will forgive the debt, and thus she does not wholeheartedly commit
herself to the betrothal, which is therefore void.
If
a woman handed a piece of gold to a craftsman and said to him: "Fashion
for me anklets, earrings, or rings, and in return for your labor I will
become betrothed to you," - it is betrothal with a a loan, which is
invalid.
