What is 'Arrears'
Overdue debt, liability or obligation. An account is said to be "in arrears" if one or more payments have been missed in transactions where regular payments are contractually required, such as mortgage or rent payments and utility or telephone bills.
BREAKING DOWN 'Arrears'
The term "in arrears" does not necessarily have a negative connotation in certain contexts such as fixed-income instruments, where it may indicate that interest payments are simply made at the end of a period. For example, mortgage interest in the U.S. is paid in arrears, which means that in the case of monthly payments, each payment covers principal repayment and mortgage interest for the month preceding the payment due date.
