How it works

There is no national alimony formula, but many courts and attorneys start from a guideline like "30% of the higher income minus 20% of the lower," capped so the recipient is not over-supported. Duration often tracks the length of the marriage.

Frequently asked questions

How long does alimony last?

It varies widely. A common rule of thumb ties duration to a fraction of the marriage length, with long marriages sometimes producing indefinite support. Judges retain broad discretion.
