What if the borrower dies and his signature is on the IOU, but not his wife's signature, and his wife denies that the IOU is in arrears?
No matter whether the husband and wife have this undivided property, no matter who borrowed it, as long as they are husband and wife, it proves that this part of the money is * * *, so when the husband leaves, the wife should also bear the responsibility of paying back the money, and should not shirk it by IOUs. This is immoral and detrimental to the reputation of being a person.
