How alimony works in Kansas
Kansas does not use a fixed statutory formula for alimony amounts. Judges weigh statutory factors — length of the marriage, each spouse's income and earning capacity, age and health, standard of living, and contributions to the marriage. Our calculator uses the AAML guideline formula (30% of payor's income minus 20% of recipient's) that attorneys commonly use for ballpark estimates.
Governing law: K.S.A. 23-2902 to 23-2904 — No statewide amount formula, but the influential Johnson County Bar guideline (about 25% of the gross-income difference, duration about one-third the marriage length) is widely cited — persuasive only.
