Key Legal Principles for 50/50 Shared Custody in New York

Statutory Framework & Court Standards

  • Equal physical custody does NOT mean zero child support if parental incomes are unequal.
  • Most Income Shares jurisdictions apply a shared parenting multiplier (1.5x) or reciprocal offset method.
  • Fixed duplicated child expenditures (housing, bedrooms, clothing, utilities) are accounted for in cross-credit offsets.
  • Health insurance and out-of-pocket medical add-ons remain apportioned strictly by income shares.

Filing & Required Court Attachments

When requesting child support orders under 50/50 Shared Custody, judges in the New York State Unified Court System & Division of Child Support Services require formal submission of official financial statements and guideline calculation schedules.
