Michael Bast, Appellant v. Shelley R. Rossoff, Respondent

Summary

The New York Court of Appeals held that the Child Support Standards Act (CSSA) applies to shared custody cases and must be applied using its three‑step statutory formula before any discretionary factors may be considered. The Court found the trial court erred by bypassing the formula and remanded for a new determination, modifying the Appellate Division's order.
