1.
dishonored check; bounced bill
The failure of a check or promissory note to be paid because the account lacks sufficient funds, so the bill is returned unpaid.
Formed from 渡る (to pass; to hand over) with the negative prefix 不: a check or 手形 that is not honored because the account lacks funds.
Common collocations
Usage
In Japan, a business that records two dishonored bills within six months is effectively shut out of bank financing, so 不渡り is treated as a serious warning sign.
