Bridge-the-gap alimony is designed to assist a party with legitimate identifiable short-term needs. Durational alimony is designed to provide a party with economic assistance for a set period of time following a marriage of short or moderate duration if there is no need for permanent support. Permanent alimony is designed to provide the needs and necessities of life as they were established during the marriage. A trial court’s discretion regarding alimony is not limitless. Rather, this discretionary authority is subject to the test of reasonableness, which requires a determination of whether there is logic and justification for the result.
