How Long Does Alimony Last in the District of Columbia?
In the District, alimony may be indefinite or term-limited, with no formula or cap on the amount or duration, and the court may make it retroactive to the date the pleading requesting alimony was filed.
Indefinite or term-limited
Under D.C. Code 16-913(b), the award of alimony may be indefinite or term-limited and structured as appropriate to the facts, and the court determines the amount and the time period. Unlike states that tie duration to the length of the marriage, the District has no percentage rule and no cap.
Length of the marriage as a factor
The duration of the marriage or domestic partnership is one of the factors, along with the time needed for the party seeking alimony to gain education or training and that party’s ability to be self-supporting. A longer marriage may support a longer or indefinite award, but the statute does not say so.
Retroactivity
An award of alimony may be retroactive to the date of the filing of the pleading that requests alimony (Section 16-913(c)). That makes the date you ask for alimony important: a request in the original complaint or answer can reach back to that filing, while a later request may not. The calculator multiplies the months from filing to the order by the monthly amount you enter to show the most a retroactive period could add up to.
Pendente lite alimony
While the case is pending, the court can award pendente lite alimony using the same factors and may make it retroactive to the filing date as well. See pendente lite alimony.
What the statute does not say
The statute sets no formula, no minimum or maximum duration, and says nothing in this section about when alimony ends or can be modified. Ask a licensed D.C. attorney what ends an order and how an order can be changed, and put those terms in any agreement.
Questions for the negotiation
Decide the amount, the period and what events change or end payments, because the statute does not set them. A written agreement should say so clearly.
