Fairfax Paternity & Child Support Lawyers
A paternity question can affect your relationship with a child, your financial responsibilities, and your ability to seek custody or visitation. You may need to establish legal parentage, respond to a support petition, or understand whether an acknowledgment you already signed can be challenged.
Virginia Family Law Center represents clients in Fairfax and throughout Northern Virginia in paternity matters and related custody and child support proceedings. We review existing records, identify the legal issues, and help you pursue the appropriate testing, agreement, or court determination.
How is paternity established in Virginia? Depending on the circumstances, Virginia law recognizes marital presumptions, a valid voluntary acknowledgment, qualifying genetic testing, and judicial or administrative proceedings. Establishing paternity identifies a child’s legal father. It does not, by itself, establish a particular parenting schedule or monthly support amount.

How Our Fairfax Paternity Lawyers Help
The first step is determining what has already happened legally. A birth certificate, signed acknowledgment, genetic test, support order, and custody order can have different consequences. We review the documents rather than assume that a missing signature or new test result resolves the case.
Depending on your circumstances, our representation can include:
- Determining whether paternity has already been legally established.
- Advising you before signing an acknowledgment of paternity.
- Evaluating rescission deadlines and grounds for challenging an acknowledgment.
- Seeking appropriate genetic testing and reviewing the resulting evidence.
- Filing or responding to a parentage petition.
- Seeking or opposing relief from an existing paternity determination.
- Addressing related custody, visitation, and child support issues.
We represent clients seeking to establish paternity and clients responding to disputed allegations. The approach depends on the existing legal relationship, the available evidence, and the relief requested.
Establishing Paternity in Virginia
Virginia Code § 20-49.1 provides several methods for establishing a parent-child relationship. The appropriate method depends in part on the mother’s marital status and whether another person is already recognized as the child’s legal father.
When the mother is married or recently divorced
Virginia recognizes a marital presumption of paternity. The Virginia Judicial System explains that when a mother is married at the time of birth or was married at any time during the preceding ten months, her husband or former husband is presumed to be the father.
If someone else may be the biological father, that presumption must be addressed through the appropriate legal process. Separation alone does not resolve the issue. The standard voluntary acknowledgment procedure should not be treated as a way to bypass an existing marital presumption.
When the parents are unmarried
Parents may establish paternity through a valid voluntary acknowledgment or another method authorized by Virginia law. If parentage is disputed, a court proceeding or assistance through the Virginia Division of Child Support Enforcement may be appropriate.
Scientifically reliable genetic testing showing at least a 98 percent probability of paternity can establish the relationship under § 20-49.1 and has the legal effect specified in that statute. Existing determinations and statutory exceptions still require consideration.
Adoption, assisted conception, and surrogacy can involve additional parentage rules. Biological testing alone does not answer every question about legal parenthood.
Signing or Challenging an Acknowledgment of Paternity
An Acknowledgment of Paternity, commonly called an AOP, is a legal document signed under oath by the mother and father. A valid acknowledgment has the same legal effect as a judgment establishing paternity. It is more than permission to add a name to a birth certificate.
Before signing, the parents must receive the required written and oral explanation of their rights, responsibilities, and the consequences of the acknowledgment, including the right to rescind.
If you are uncertain about biological parentage or believe someone else is already the legal father, obtain advice before signing.
The 60-day rescission period can end earlier
Under Virginia Code § 20-49.1(B)(2), either party may rescind an acknowledgment within 60 days after signing unless, before rescission, an administrative or judicial order relating to the child is entered in an action to which that person was a party.
Do not assume you always have the full 60 days. The date of signing, any subsequent proceedings, and the required rescission procedure should be reviewed promptly.
Challenges after the rescission opportunity has ended
The statute makes an acknowledgment binding and conclusive unless a subsequent judicial proceeding establishes that it resulted from fraud, duress, or a material mistake of fact. A change of mind or the end of the parents’ relationship is not, by itself, one of those grounds.
Legal responsibilities generally remain in effect while the acknowledgment is challenged, unless the court finds good cause to suspend them.
In Matzuk v. Price, Record No. 1635-18-2 (Va. Ct. App. June 11, 2019), the Court of Appeals upheld a finding that an acknowledgment resulted from a material mistake of fact. On that record, uncertainty about biological fatherhood when the acknowledgment was signed did not prevent the finding. The decision illustrates why the evidence and circumstances of signing matter; it does not make every acknowledgment automatically reversible.
Genetic Testing and Disputed Paternity
Genetic testing can provide important evidence, but the test must be suitable for the legal proceeding. An informal home test should not be assumed to satisfy court requirements.
Virginia Code § 20-49.3 addresses court-ordered testing and the admission of test reports. It includes requirements concerning a qualified expert’s sworn report and filing the results at least 15 days before the hearing or trial when using that statutory procedure.
Our review can address:
- Whether testing is needed and which procedure applies.
- Whether an existing acknowledgment or order must first be addressed.
- The laboratory report, identification procedures, and supporting documentation.
- Applicable filing deadlines and any request to question the testing expert.
Virginia law also recognizes evidence beyond genetic testing. Virginia Code § 20-49.4 establishes a clear-and-convincing-evidence standard for actions to establish parentage and identifies relevant types of evidence.

Can an Existing Paternity Determination Be Set Aside?
Sometimes, but relief is not automatic.
Virginia Code § 20-49.10 allows a petition for relief from a legal determination of paternity when scientifically reliable genetic testing performed in accordance with the parentage statutes excludes the person named as father. The court must appoint a guardian ad litem to represent the child’s interests.
The statute prohibits relief under that section when the person named as father:
- Acknowledged paternity knowing he was not the father.
- Adopted the child.
- Knew that the child was conceived through artificial insemination.
An existing acknowledgment may also require analysis under § 20-49.1. The documents, earlier findings, testing, and circumstances of the acknowledgment must be considered together.
What happens to existing child support?
A new test result does not itself cancel a support order. Section 20-49.10 limits retroactive modification: relief affecting support during a pending petition may reach back only to the date notice of that petition was served on the nonfiling party.
Do not assume that previously accrued support will disappear or that earlier payments will be refunded. Seek a court determination before changing payments on your own.
Challenging parentage can also affect the legal basis for custody or visitation. Before proceeding, discuss both the financial consequences and the potential effect on your relationship with the child.
Does Establishing Paternity Give a Father Custody or Visitation?
Establishing paternity does not automatically create a custody order or parenting schedule. It establishes the legal parent-child relationship. Custody and visitation require their own analysis and, when disputed, an appropriate court determination.
Virginia courts decide custody and visitation according to the child’s best interests. Virginia Code § 20-124.3 directs courts to consider factors including the child’s needs, each parent’s relationship with the child, caregiving roles, cooperation, and relevant safety concerns.
A parentage proceeding may also address custody and visitation when the court has jurisdiction and those issues are properly before it. Related relief should be requested deliberately rather than assumed to follow automatically from a paternity finding.
Our custody and visitation attorneys help clients address decision-making authority, parenting schedules, and exchanges. Our custody without marriage page explains related concerns for unmarried parents.
Child Support and Pregnancy Expenses After Paternity Is Established
Establishing parentage provides a legal foundation for determining support obligations. Virginia generally calculates child support using statutory guidelines that consider both parents’ incomes, the custody arrangement, and qualifying expenses.
The amount is not automatically whatever one parent requests, and an acknowledgment does not itself establish a specific monthly payment. Our child support lawyers can help evaluate the financial information and applicable calculation.
When can support begin?
Virginia Code § 20-49.8 permits a parentage judgment to address support and expenses incurred on behalf of the child from the filing of the parentage proceeding, subject to due diligence in service. An earlier Department of Social Services support order delivered for service can affect the starting date.
Do not assume that an initial award automatically reaches back to the child’s birth. Filing dates, service, and existing proceedings matter.
Pregnancy, delivery, and expenses before birth
A separate provision applies when the initial parentage petition is commenced within six months of the child’s live birth. Unless there is good cause or a different agreement, § 20-49.8(B) requires allocation between the legal parents, in proportion to their guideline gross incomes, of the mother’s unreimbursed pregnancy and delivery expenses and reasonable expenses either parent incurred for the child before birth.
Keep medical bills, insurance explanations of benefits, receipts, and proof of payment. The statute defines covered pregnancy and delivery expenses and addresses credits and government-paid costs. This issue should be evaluated promptly if the child was recently born.
If a support order already exists, changing or enforcing it requires separate consideration. Learn more about our support modification and court order enforcement services.
What Does a Paternity Case Involve?
Parentage matters are commonly handled in juvenile and domestic relations district court. Under Virginia Code § 20-49.2, circuit courts also have concurrent original jurisdiction when parentage is at issue in a matter otherwise before the circuit court.
The appropriate filing depends on the existing proceedings, orders, parties, and requested relief. A case may involve:
- Reviewing the current legal status. Examining acknowledgments, birth records, marriage or divorce records, and earlier orders.
- Identifying the proper parties and court. Addressing existing legal parents and any jurisdictional issues.
- Filing and serving the appropriate papers. Clearly requesting the parentage determination and related relief needed.
- Obtaining and presenting evidence. Arranging qualifying testing where appropriate and preparing supporting records and testimony.
- Resolving related issues. Addressing support, custody, visitation, and birth-record changes as authorized.
A straightforward acknowledgment and a contested case involving an existing legal father require different work. The scope of representation and anticipated costs should reflect the actual dispute.
