California DCSS Process: Complete 2026 Step by Step Guide

Quick Answer The California Department of Child Support Services (DCSS) provides free services to establish, modify, and enforce child support orders. California Family Code section 17000 et seq. governs DCSS authority. Each California county has a Local Child Support Agency (LCSA) that delivers these services locally. San Bernardino County DCSS can be reached at (866) 901-3212. Services are free for all parents regardless of income level. DCSS can establish paternity, calculate support using the guideline formula, obtain court orders, enforce orders through wage garnishment under California Family Code section 17400, suspend driver’s and professional licenses under California Family Code section 17410, intercept tax refunds and lottery winnings, seize bank accounts, and coordinate with other states under the Uniform Interstate Family Support Act (UIFSA). DCSS does not handle custody, visitation, divorce, or property issues – only child support. For those issues, a private family law attorney is necessary. Federal Title IV-D at 42 U.S.C. sections 651 through 669 establishes the framework requiring state child support agencies.

What DCSS Is and Does

The California Department of Child Support Services (DCSS) is the state agency responsible for child support enforcement. DCSS operates under California Family Code section 17000 et seq. and federal Title IV-D of the Social Security Act at 42 U.S.C. sections 651 through 669.

DCSS works through Local Child Support Agencies (LCSAs) in each county. The LCSA is your direct contact for child support services. In San Bernardino County, the LCSA is the San Bernardino County Department of Child Support Services.

DCSS provides services in four main areas:

1. Establishing paternity for children of unmarried parents
2. Establishing child support orders
3. Enforcing existing child support orders
4. Modifying child support orders when circumstances change

DCSS does NOT handle custody, visitation, divorce, property division, spousal support, restraining orders, or other family law matters. Those issues require a private family law attorney or self represented action in family court.

DCSS Services Are Free

DCSS services are free for all parents regardless of income level. There are no application fees, hourly charges, or other costs. This makes DCSS an extremely valuable resource for child support matters. A board-certified family law specialist can help with custody, divorce, and other family law issues that DCSS does not handle.

DCSS receives federal funding under Title IV-D, which prohibits charging fees to most users. The minor exceptions include:

• Annual $35 fee for cases where the custodial parent has never received public assistance (federal requirement)
• Genetic testing fees in some paternity cases (often recoverable if paternity is established)

Beyond these minor fees, DCSS services are completely free. The free service model means DCSS can deliver substantial benefits to families who could not otherwise afford private attorneys for child support matters.

When to Use DCSS

DCSS is appropriate in many situations:

Establishing Initial Orders

When no child support order exists, DCSS can establish one. This is particularly valuable when:

• Parents were never married and need to establish paternity first
• Parents have not pursued divorce or legal separation
• Cooperative parents who simply need formal orders
• Custodial parents who cannot afford private attorneys

Enforcement of Existing Orders

DCSS has powerful enforcement tools not available to private attorneys:

• Automatic wage garnishment through income withholding orders
• Driver’s and professional license suspension
• Tax refund interception (state and federal)
• Bank account seizures
• Passport denial for arrears over $2,500
• Coordinated interstate enforcement

Interstate Cases

DCSS coordinates with other states’ child support agencies under the Uniform Interstate Family Support Act (UIFSA). This coordination is automatic and free, providing significant value for cases where parents live in different states.

Modification Requests

DCSS can file modification motions when circumstances have changed. This is particularly useful when the obligor’s income has increased and the custodial parent cannot afford a private attorney.

DCSS vs Private Attorney

Understanding when DCSS is appropriate versus when private representation is needed:

Issue	DCSS	Private Attorney
Child support establishment	Yes, free	Yes, paid
Child support enforcement	Yes, strong tools	Yes, but limited tools
Custody and visitation	No	Yes
Divorce and property	No	Yes
Spousal support	No	Yes
Restraining orders	No	Yes
Cost	Free	$2,500 to $25,000+
Speed	Often slower (6+ months)	Often faster

Many parents use both DCSS and a private attorney. DCSS handles child support while a private attorney handles divorce, custody, and other matters. This combination provides comprehensive coverage at lower total cost than using a private attorney for everything.

How to Open a DCSS Case

Opening a DCSS case is straightforward:

• Contact your county’s Local Child Support Agency (LCSA)
• Complete the application (online, by mail, or in person)
• Provide required information about the other parent
• Provide information about your children
• Provide income and employment information for both parents if known
• Submit any existing court orders
• DCSS assigns a case number and worker
• Initial appointment may be scheduled
• DCSS begins the establishment or enforcement process

Required Information

Information needed to open a case includes:

• Names, dates of birth, and Social Security numbers of all parties
• Current addresses of all parties
• Employer information for the obligor parent
• Income information for both parents
• Bank account information for direct deposit (optional)
• Children’s birth certificates
• Any existing court orders
• Information about other children supported by either parent

San Bernardino County Application

San Bernardino County DCSS can be reached at (866) 901-3212. Applications can be completed online through the California Child Support Self Service Website, by mail, or in person at the local office. The agency serves residents throughout San Bernardino County including Ontario, Rancho Cucamonga, Fontana, Redlands, Chino Hills, Victorville, Hesperia, Apple Valley, and other communities.

Paternity Establishment

For children of unmarried parents, paternity must be established before child support can be ordered. DCSS handles paternity establishment under California Family Code section 17400.

Voluntary Paternity

Both parents can voluntarily establish paternity by signing a Voluntary Declaration of Paternity. This is often done at the hospital when the child is born or can be done later through DCSS. The declaration has the same legal effect as a court order establishing paternity.

Genetic Testing

If paternity is disputed, DCSS orders genetic testing. The testing uses DNA samples (usually cheek swabs) from the child, mother, and alleged father. Results typically establish paternity to a 99 percent or higher probability or exclude the alleged father conclusively.

Court Order Establishing Paternity

Based on voluntary declaration, genetic test results, or other evidence, DCSS obtains a court order establishing paternity. The order:

• Legally establishes the parent child relationship
• Allows establishment of child support
• Allows the parent to seek custody and visitation rights
• Adds the parent to the child’s birth certificate
• Establishes the child’s right to inherit
• Establishes the child’s eligibility for survivor benefits

Establishing Support Orders

After paternity is established (or in cases of married parents), DCSS establishes the support order. California Family Code section 17400 authorizes DCSS to file and obtain these orders.

Guideline Calculation

Child support is calculated using the California guideline formula in California Family Code section 4055. The formula considers:

• Each parent’s monthly gross income
• Percentage of time each parent has primary physical responsibility
• Number of children
• Tax filing status
• Mandatory deductions
• Health insurance and union dues
• Other children supported

The DCSS Guideline Calculator runs this complex calculation automatically. The calculator is available free online through the California Department of Child Support Services website.

Order Process

The order establishment process:

1. DCSS attempts negotiated agreement with the obligor parent
2. If agreement is reached, parties sign a stipulated order
3. If no agreement, DCSS files a request with the court
4. Court schedules a hearing
5. Both parents may appear at the hearing
6. Court enters the order based on the guideline calculation
7. Order becomes effective and enforcement begins

Enforcement Tools

DCSS has powerful enforcement tools not available to private attorneys:

Income Withholding

California Family Code section 17400 authorizes DCSS to issue income withholding orders directly to employers. The employer must withhold child support from the obligor’s pay and send it directly to the State Disbursement Unit. This is automatic and effective in most cases.

License Suspension

California Family Code section 17410 authorizes DCSS to suspend licenses for unpaid support, including:

• Driver’s licenses
• Professional licenses (medical, legal, real estate, etc.)
• Recreational licenses (fishing, hunting)
• Commercial licenses

License suspension is highly effective because most obligors quickly find ways to pay rather than lose their ability to work or drive.

Tax Refund Intercept

DCSS can intercept state and federal tax refunds for unpaid support. The interception is automatic when arrears exceed specific thresholds. The intercepted amount goes directly to the custodial parent.

Bank Account Seizure

DCSS can seize funds from bank accounts to pay arrears. Financial institutions must comply with the seizure orders. Joint accounts are subject to specific procedural protections for the non obligor account holder.

Passport Denial

Federal law authorizes denial of passport applications for parents with arrears over $2,500. This can prevent international travel and is highly motivating for many obligors.

Lottery and Settlement Intercepts

California lottery winnings and various legal settlements (workers compensation, personal injury) can be intercepted for unpaid support.

Credit Reporting

Unpaid child support over specific thresholds is reported to credit bureaus, affecting the obligor’s credit score and ability to obtain credit, housing, or employment.

Contempt and Criminal Referral

In severe cases, DCSS can refer cases for contempt of court or criminal prosecution. Federal law makes willful failure to pay child support a federal crime in certain interstate cases.

Modification Through DCSS

DCSS can file modification motions when circumstances have changed. The standard for modification is the same as private cases: a material change in circumstances that would result in a guideline calculation differing by 20 percent or $50 monthly, whichever is less.

Common Modification Triggers

• Significant income change for either parent
• Job loss or new employment
• Custody schedule changes affecting percentage of time
• New child for either parent
• Health insurance changes
• Significant medical expenses
• Other support obligations

DCSS Review Process

DCSS conducts a three year automatic review for cases receiving public assistance. For other cases, either parent can request a review every 3 years or sooner if circumstances change. The review process:

• Parent requests review by submitting a modification request
• DCSS gathers current income information from both parents
• DCSS recalculates support using the guideline formula
• If modification is warranted, DCSS attempts negotiated agreement
• If no agreement, DCSS files motion with the court
• Court hearing and modification order if appropriate

Interstate Cases

DCSS coordinates with other states’ child support agencies under the Uniform Interstate Family Support Act (UIFSA). This coordination is automatic and significantly improves interstate enforcement.

UIFSA Coordination

When the obligor parent lives in another state, DCSS can:

• Coordinate with the other state’s child support agency
• Send income withholding orders directly to out of state employers
• Register California orders in other states for enforcement
• Receive other states’ orders for registration and enforcement in California
• Access the Federal Parent Locator Service to find missing parents
• Apply federal enforcement tools including passport denial and tax intercept

International Cases

Some international child support enforcement is available through the Hague Convention on the International Recovery of Child Support. The United States is a signatory to this convention. International cases are typically more complex and may not have the same enforcement effectiveness as domestic cases.

Working with DCSS Effectively

Tips for effective DCSS interaction:

• Respond promptly to all DCSS communications
• Provide accurate and complete information
• Update address and employment information immediately
• Keep records of all DCSS communications
• Attend all required appointments and hearings
• Understand that DCSS represents the children’s interests, not yours specifically
• Coordinate with your private attorney on related family law matters
• Use the online portal for case status and payment information
• Be patient as DCSS handles a large caseload

Communication delays are common given the large caseload DCSS handles. Persistent follow up is sometimes necessary to keep cases moving.

Frequently Asked Questions

Q: Are DCSS services really free?

A: Yes. DCSS services are free for all parents regardless of income level. California Family Code section 17000 et seq. and federal Title IV-D establish the framework. There are no application fees, hourly charges, or other costs for the vast majority of services. The minor exceptions are a $35 annual fee for cases where the custodial parent has never received public assistance (federal requirement) and genetic testing fees in some paternity cases (often recoverable if paternity is established). DCSS receives federal funding under Title IV-D, which prohibits charging fees to most users. This free service model makes DCSS valuable for families who could not otherwise afford private attorneys for child support matters.

Q: How do I open a DCSS case?

A: Contact your county’s Local Child Support Agency (LCSA). In San Bernardino County, call (866) 901-3212. You can apply online through the California Child Support Self Service Website, by mail, or in person. Provide information about both parents, your children, and any existing court orders. Required information includes names, dates of birth, Social Security numbers, current addresses, employer information for the obligor parent, income information for both parents, children’s birth certificates, and any existing court orders. DCSS will assign a case number and worker who will guide you through the process. Initial appointments may be scheduled. The process for opening a case typically takes a few weeks.

Q: What does DCSS NOT do?

A: DCSS does not handle custody, visitation, divorce, property division, spousal support, restraining orders, name changes, adoptions, paternity disputes outside support matters, or any other family law issue beyond child support. These matters require a private family law attorney or self represented action in family court. Many parents use both DCSS (for child support) and a private attorney (for divorce, custody, and other matters). This combination provides comprehensive coverage at lower total cost than using a private attorney for everything. DCSS represents the children’s interest in receiving support, not the custodial parent’s interests specifically.

Q: How long does it take DCSS to establish a child support order?

A: Establishment typically takes 6 to 12 months from application to final order. The timeline depends on cooperation level, complexity of paternity issues, the obligor parent’s location and employment status, and DCSS caseload. Cases requiring genetic testing for paternity take longer. Interstate cases involving multiple states take longer. Simple cases with cooperative parents and clear paternity can sometimes be completed in 3 to 6 months. Cases where the obligor parent cannot be located or refuses to cooperate may take significantly longer. Private attorneys can sometimes establish orders faster (3 to 6 months) but charge $2,500 to $7,500 for the service.

Q: Can DCSS help me collect back child support?

A: Yes. DCSS has powerful enforcement tools for collecting arrears including income withholding under California Family Code section 17400, license suspension under California Family Code section 17410 (driver’s, professional, and recreational licenses), tax refund interception (state and federal), bank account seizures, passport denial for arrears over $2,500, lottery and settlement intercepts, credit bureau reporting, and contempt or criminal referrals in severe cases. These tools are not available to private attorneys. DCSS handles enforcement of both current support obligations and accumulated arrears. There is no statute of limitations on collecting child support arrears in California, so DCSS can pursue collection regardless of how old the debt is.

Q: Can DCSS modify my child support order?

A: Yes. DCSS can file modification motions when circumstances have changed. The standard for modification is a material change in circumstances that would result in a guideline calculation differing by 20 percent or $50 monthly, whichever is less. Common triggers include significant income change for either parent, job loss or new employment, custody schedule changes, new children for either parent, health insurance changes, and significant medical expenses. DCSS conducts automatic three year reviews for cases receiving public assistance. For other cases, either parent can request a review every 3 years or sooner if circumstances change. The modification process typically takes 3 to 6 months.

Q: Can I use DCSS if my ex lives in another state?

A: Yes. DCSS coordinates with other states’ child support agencies under the Uniform Interstate Family Support Act (UIFSA). This coordination is automatic and free. DCSS can send income withholding orders directly to out of state employers, register California orders in other states for enforcement, receive other states’ orders for registration and enforcement in California, access the Federal Parent Locator Service to find missing parents, and apply federal enforcement tools including passport denial and tax intercept. Interstate enforcement through DCSS is highly effective and far less expensive than hiring private attorneys in multiple states. This is one of DCSS’s most valuable services for many families.

Q: Should I use DCSS or a private attorney for child support?

A: Many parents benefit from using both. DCSS handles child support establishment, enforcement, and modification at no cost. DCSS has powerful enforcement tools not available to private attorneys including license suspension and tax intercept. However, DCSS only handles child support, not custody, visitation, divorce, or other family law matters. Private attorneys can handle the entire family law case as an integrated matter and typically work faster than DCSS. For families with complex custody, property, or divorce issues alongside child support, a private attorney coordinates everything. For families with only child support concerns and limited financial resources, DCSS is an excellent option. Some families use DCSS for ongoing child support enforcement while using private attorneys for divorce and custody establishment.

Bottom Line

The California Department of Child Support Services (DCSS) provides free services to establish, modify, and enforce child support orders under California Family Code section 17000 et seq. and federal Title IV-D at 42 U.S.C. sections 651 through 669. San Bernardino County DCSS can be reached at (866) 901-3212. DCSS can establish paternity, calculate guideline support under California Family Code section 4055, obtain court orders, and enforce orders through wage garnishment, license suspension under California Family Code section 17410, tax intercept, bank seizures, passport denial, and other tools. DCSS does NOT handle custody, visitation, divorce, property, spousal support, or other family law matters – those require a private attorney. Many families use both DCSS (for child support) and a private family law attorney (for other matters) for comprehensive coverage at lower total cost. UIFSA coordination through DCSS makes interstate child support enforcement effective and free.

If you need help with divorce, custody, or other family law issues that DCSS does not handle, a free consultation with a board-certified family law specialist can help you understand how to coordinate DCSS services with your overall family law strategy.
