Permanent alimony or limited duration alimony can be awarded. The time period over which alimony must be paid generally depends upon the length of the marriage. Other types of alimony may be awarded in specific cases. For example, rehabilitative alimony can be awarded to allow one spouse to complete an education program. Alimony can also be awarded based on the fact that one spouse supported his or her spouse during a period of education so that that spouse was able to reach a higher earning standard.
