Key Legal Principles for Sole Custody Guidelines in Massachusetts

Statutory Framework & Court Standards

  • The non-custodial parent (obligor) is responsible for their full statutory share or percentage without parenting-time offsets.
  • Self-Support Reserve (SSR) protections prevent child support orders from pushing the payor below the federal or state poverty threshold.
  • Mandatory deductions (FICA, mandatory retirement, union dues, prior child support orders) reduce gross income before calculating obligation.
  • Direct payments (buying clothes, groceries during visitation) do not count toward official court-ordered child support.

Filing & Required Court Attachments

When requesting child support orders under Sole Custody Guidelines, judges in the Massachusetts Probate and Family Court Department require formal submission of official financial statements and guideline calculation schedules.
