change of circumstances
n. the principal reason for a court modifying (amending) an existing order for the payment of alimony and/or child support. The change may be an increase or decrease in the income of either the party obligated to pay or the ex-spouse receiving payment, or the health, the employment, or needs of either party. Thus, if an ex-husband's income is substantially increased or the ex-wife becomes ill and cannot work, the judge may order the ex-husband to pay her more. Remarriage of a spouse who is receiving alimony automatically terminates the alimony order, unless there is a special provision that it continue, which is rare.
