Update history
- — Attorney feedback follow-up: New York now computes guideline spousal maintenance together with child support. An optional section calculates the presumptive maintenance award (post-divorce, temporary, or Family Court spousal support) using the statutory two-formula, lower-controls method with the $241,000 payor income cap (effective March 1, 2026) and the self-support-reserve adjustment, shows the advisory duration schedule for post-divorce awards, and then — as the statute requires — recalculates child support with the maintenance subtracted from the payor’s income and added to the payee’s. The CSSA recitation includes the full maintenance calculation when enabled, and the MCP tool accepts an optional maintenanceGuideline block for the same combined calculation.
- — Several fixes and additions from attorney feedback: maintenance paid between the two parents is now added to the receiving parent's income as well as deducted from the paying parent's (previously only deducted), matching the statute; each parent’s pro rata share of combined income is now shown up front, along with each parent's dollar share of any child care, health insurance, or unreimbursed-medical add-ons; the order is now also shown converted to weekly, bi-weekly, semi-monthly, and monthly pay-cycle equivalents; and a new "Copy CSSA recitation" button builds a plain-text summary of the full calculation, in the order NY agreements and judgments typically recite it, for pasting into a draft.
- — Support orders can no longer go negative when add-on credits exceed the basic obligation.
- — New York went live under the Child Support Standards Act, using the LDSS-4515 chart (Rev. 03/26, effective 2026-03-01).
