Although there are always exceptions, alimony is generally paid out for the amount of time equivalent to the length of the marriage; this is called durational alimony. To make sure the life insurance policy holder always pays a fair and reasonable amount of alimony, it can be adjusted should an ex-spouse experience a drastic reduction in income, such as the loss of a job or retirement. If alimony payments are reduced, life insurance will be reduced accordingly as well.
