Nonparent (third-party) child support cases can be more complicated than standard two-parent support matters. If you’re caring for a child and need a support order established (or updated), we can help prepare a clean, organized filing packet.

What “nonparent” child support means

A nonparent child support case may involve a third party (for example, a relative or other caregiver) who is providing day-to-day care and needs support established against one or both parents. These cases often involve more than two parties and more procedural steps.

Why these cases are often more complex

  • Multiple parties: the petitioner plus one or both parents may be involved.
  • Service requirements: you may need service packets and proof of service for each parent.
  • More supporting detail: declarations and exhibits often matter more because the court needs context.
  • Related issues: custody or parenting plan issues may be connected to the support request.

Documents we prepare

  • Petitions and/or motions (as applicable to your situation)
  • Declarations and supporting statements
  • Financial declarations and required worksheets
  • Service packets and copies needed for service on each parent
  • Proposed orders

What to gather before filing

  • Any existing court orders involving the child (custody, parenting plan, guardianship, support)
  • Full names and contact information for all parties
  • Any income information you have for each parent (if known)
  • Child-related costs (medical, daycare, school or special needs expenses)
  • A timeline of care (when the child began living with you and what support has been provided)
