Default[edit]
Main article: Default (finance)
Default occurs when the debtor has not met its legal obligations according to the debt contract, e.g.- it has not made a scheduled payment, or has violated a covenant in the debt contract. Default may occur if the debtor is either unwilling or unable to pay its debt. This can occur with all debt obligations including bonds, mortgages, loans, and promissory notes.
If the debt owed becomes beyond the possibility of repayment, the debtor faces insolvency or bankruptcy; in the United Kingdom and some states of the United States until the mid-19th century, debtors could be imprisoned in debtor's prisons, while in some countries such as Greece debtors are still imprisoned.
