New Mexico's child support program was reorganized in 2023–2024, moving from the Human Services Department into the newly created Health Care Authority. Older documents may still reference the previous agency name during the transition.
The division locates noncustodial parents, establishes paternity, sets support orders, and collects and enforces payments once a case is active, with field offices in cities including Albuquerque and Las Cruces in addition to the central Santa Fe office.

How to Apply for Child Support in New Mexico
A parent or caretaker of a child can apply for New Mexico child support services through the YES.NM.gov online portal. Families already receiving TANF or Medicaid in New Mexico are typically referred for services automatically.
The application requires identifying information for both parents and the child, along with any existing custody or support paperwork. HCA then works to establish paternity if needed and get a support order in place.
How to Collect Child Support Payments in New Mexico
New Mexico collects most support through income withholding once an order is active, disbursed to the receiving parent by direct deposit or debit card.
Payments can also be made online through the state's Paydici payment portal, and both parents can check case status through the YES.NM.gov portal.
Missed Payments & Enforcement
HCA's enforcement remedies page lists tools including tax refund interception, license suspension, and credit bureau reporting for parents who fall behind on payments.
As in every state, federal law allows a passport to be denied or revoked once past-due support exceeds $2,500.
