How Child Support Is Organized in New Mexico

Child support in New Mexico is run by the state, not by individual cities or counties. The Child Support Services Division, part of the New Mexico Health Care Authority, operates the program statewide. Until the 2024 reorganization it sat inside the Human Services Department, and older forms and web pages still use that name. Field offices handle the face-to-face work. Our directory lists 15 of them, from Farmington in the northwest to Hobbs and Clovis near the Texas line.

Every listing follows the same naming pattern, such as the Albuquerque Child Support & Social Service Office or the Roswell Child Support & Social Service Office. Your case belongs to the state, not to one building. Staff at any location, or the statewide line, can generally look it up and tell you what is happening.

One Statewide Number, Many Offices

Fourteen of the 15 listings in our database show the same toll-free number, 800-288-7207. Gallup is the exception, with a local line at 505-863-9545. Calling the statewide number first is usually the fastest way to learn whether you need to come in at all. Questions about a missed payment or a changed address can often be handled by phone.

The Laws Behind the Offices

New Mexico sets support amounts through statutory child support guidelines in its domestic relations law, found at NMSA 40-4-11.1. The guidelines use an income-shares approach. They add together both parents' incomes, estimate the cost of raising the child, and divide that cost in proportion to each parent's share. Health insurance and work-related child care costs are factored in as well. A judge may depart from the guideline amount, and is expected to explain why.

Paternity cases fall under the New Mexico Uniform Parentage Act. When a parent lives in another state, the Uniform Interstate Family Support Act lets New Mexico and the other state work together on one order. Orders themselves come from the state's district courts, so the field office is your partner in the process, not the final decision-maker.

What a New Mexico Child Support Office Can Do for You

A field office does not give legal advice, and its attorneys represent the state rather than either parent. Within that limit, the services are broad. Either parent can apply, and so can a grandparent or other caretaker raising the child. Families who receive certain public assistance, including cash assistance and some Medicaid cases, may be referred to the program automatically. Everyone else can apply on their own.

Typical services include:

Enforcement is where the state's reach matters most. Income withholding sends payments straight from an employer's payroll. Other tools commonly available to state programs include intercepting tax refunds, reporting unpaid support to credit bureaus, and restricting licenses or passports in serious cases. Payments normally move through a state payment system rather than from one parent to the other, which creates a clear record for both sides.

Ask staff at your first contact whether any application or annual fees apply to your case. Fee rules can depend on whether you have received public assistance, so do not assume a number you heard from a friend.

Albuquerque, Rio Rancho, Los Lunas and Santa Fe: Central New Mexico Offices

The Albuquerque Child Support & Social Service Office sits at 1010 18th Street Northwest, in Bernalillo County, the most populous county in the state. Expect more walk-in traffic here than at small-town offices. Call ahead and ask whether an appointment will save you a wait.

Two neighboring offices handle the suburbs. The Rio Rancho Child Support & Social Service Office at 4363 Jager Way Northeast is the listing for Sandoval County. The Los Lunas Child Support & Social Service Office at 445 Camino Del Rey Southwest is the listing for Valencia County, along the Rio Grande south of Albuquerque. Many residents of these two counties commute into the city for work. That matters little for filing, but it can matter for wage withholding if an employer is based in Bernalillo County. Withholding orders follow the employer, not your home address.

Santa Fe is different. The Santa Fe Child Support & Social Service Office lists a mailing address, PO Box 2348, and so does Crownpoint. A post office box is not a place you can walk into, so phone first and ask for the street address where staff meet clients. The Taos Child Support & Social Service Office, at 145 Roy Road, serves northern New Mexico in Taos County.

Gallup, Crownpoint, Shiprock and Farmington: The Northwest

The northwest corner has some of the longest drives to a state office. McKinley County has two listings: the Gallup Child Support & Social Service Office at 3006 West Historic Highway 66, and the Crownpoint Child Support & Social Service Office, which lists PO Box 1940. San Juan County also has two: the Farmington Child Support & Social Service Office at 1800 East 30th Street and the Shiprock Child Support & Social Service Office on US Highway 666 N.

One practical tip: US Highway 666 was renumbered US 491 in 2003. Older listings keep the earlier name, so if a map app cannot find the Shiprock address, search for Shiprock and then confirm the location by phone.

Large parts of both counties lie within the Navajo Nation, which operates its own child support program under tribal law. One parent may live or work on the Navajo Nation while the other lives in a border town like Gallup or Farmington. In that situation, ask the state office how state and tribal orders will be coordinated, and bring any tribal court paperwork you already have. Gallup is the only listing in our database with its own local number, so use 505-863-9545 for questions specific to that location.

Rural distances change how you plan. Gas, child care and time off work all add up, so use the phone and mail wherever staff allow before making a trip.

Southern and Eastern New Mexico: Las Cruces, Deming, Silver City, Hobbs, Roswell and Clovis

In the south, the Las Cruces Child Support & Social Service Office at 653 Utah Avenue is the listing for Doña Ana County, one of the largest counties in the state by population. Farther west, the Deming Child Support & Social Service Office at 910 East Pear Street is in Luna County, and the Silver City Child Support & Social Service Office at 3088 East 32nd Street is in Grant County.

The eastern plains have three offices: Clovis at 3316 North Main Street in Curry County, Hobbs at 2120 North Alto Drive in Lea County, and Roswell at 2732 Wilshire Boulevard in Chaves County. Hobbs and Clovis are close to Texas, so interstate cases are common there. Under the interstate family support law, an income withholding order can go directly to an employer in another state, which helps when a parent works across the line. Parents in oilfield or other jobs with changing schedules should keep pay records, since variable income is a common reason to ask for an order review.

Whichever office is closest, confirm hours before you go. State offices generally keep weekday business hours and may close on state holidays.

The child support program in New Mexico is administered by the state's child support enforcement agency, which operates through a network of county-level offices that handle case intake, order establishment, payment processing, and enforcement across the state under the authority of Title IV-D of the Social Security Act.

Child Support Offices locations are available in 15 cities across New Mexico. They are spread across 13 counties.

Cities with the highest concentration include Clovis, Roswell, Gallup, which serve as regional hubs for child support case processing and interstate enforcement coordination for cases involving parents in multiple states.

Non-custodial parents in New Mexico who are current on their support obligation and experiencing a significant change in income — such as job loss or medical disability — may be eligible to request a formal modification review through the state child support agency without having to hire an attorney.

Custodial parents in New Mexico who receive public assistance are automatically enrolled in child support services as a condition of TANF or Medicaid eligibility. Parents not receiving public assistance can still apply for child support services voluntarily and typically receive the same level of enforcement assistance at little or no cost.

Preparing for Your First Contact With a New Mexico Child Support Office

A little preparation makes a first call or visit far more productive. Gather the basics before you contact the Santa Fe, Las Cruces or any other New Mexico field office. Caseworkers need enough detail to find the other parent and to calculate support accurately.

Useful items to have on hand include your photo ID and Social Security number, the child's birth certificate and Social Security number, and the other parent's full name, birth date, last known address and employer. Add any existing court order, divorce decree or paternity paperwork, and recent pay stubs or tax returns showing your income. If you already receive support, bring payment records or bank statements.

Write down your questions beforehand, and keep a log of dates, names and what you were told. Ask for your case number at first contact, because every later call goes faster when you can give it. If you are more comfortable in Spanish or Navajo, ask about interpreter help. Agencies that receive federal funds are expected to provide language access.

Remember that the office enforces the order you have. It cannot change that order on its own. Only a judge can modify an order, so if your situation has changed, ask staff how to request a review. Until a change is approved, the current amount remains due.

Finally, pay through the official channel. Informal cash payments that bypass the state payment system may not be credited to your case, and that can create a dispute later over what is owed.

Child Support Questions From New Mexico Families

Contact the Child Support Services Division through the statewide line, 800-288-7207, or visit one of the 15 field offices listed here, such as the Farmington or Hobbs office. Staff will ask about both parents, the child and any existing orders, then open a case. Either parent or a caretaker can apply. If you already receive cash assistance or certain Medicaid benefits, a referral may already exist, so ask staff to check before you file again. Bring identification and any court paperwork you have, and ask about fees when you apply.

No. Child support in New Mexico is a statewide program, so your case is not tied to the building where you applied. A parent in Deming can call the Las Cruces office, and a parent in Rio Rancho can use the Albuquerque office. Choose whichever location is easiest to reach, or simply use the toll-free number. The county matters mainly for the court that issues your order, which depends on where the parents and child live. Staff can tell you which district court applies to your situation.

New Mexico can work across borders. Under the Uniform Interstate Family Support Act, the state can ask another state to establish or enforce an order, and it can send income withholding notices to out-of-state employers. For parents who live or work on the Navajo Nation, the tribe runs its own child support program, and the state office can explain how the two systems coordinate. Offices in Gallup, Crownpoint, Shiprock and Farmington see these cases often. Bring any tribal court orders you already have so staff can review them.

In general, support continues until the child turns 18. State law allows it to run longer in some situations, such as when a child is still attending high school, and a court order may state its own end date. Unpaid support, called arrears, can remain owed after the child reaches adulthood. Do not stop paying, or expect payments to stop on a birthday, until you have confirmed the terms of your order. Read the order itself or ask your field office, and request a review if circumstances change.

Tell your office right away, and pass along any new address, employer or contact details you have. Enforcement tools include income withholding, state and federal tax refund interception, credit reporting and license restrictions. In serious cases, the state may ask a court to hold a parent in contempt. Keep your own records of what you received, because they help resolve disputes. Enforcement takes time, and staff cannot promise a collection date, but a well-documented case generally moves faster than one with missing information.

Yes. If income, custody time, health insurance costs or child care costs have changed significantly, ask your office whether a review is appropriate. The state can help request a modification, but only a judge can approve a new amount. Until then, the existing order stays in force, and unpaid amounts can keep growing. Gather recent pay stubs, tax returns and documents about the change, such as a layoff notice or a new custody schedule. For personal legal advice, talk to a private attorney or a legal aid group, since the state's attorneys do not represent you.
