Denver Paternity Lawyer

At VanLandingham Law, LLC, we represent both mothers and fathers in Denver paternity matters. Paternity creates the legal relationship between a child and father, and that relationship carries lasting implications for custody, child support, inheritance, and access to medical history. When the stakes are this high, having an attorney who understands the full picture matters.

Paternity issues commonly arise during separation, divorce, custody disputes, or child support proceedings. Colorado law governs both the establishment and challenge of paternity, and how that process unfolds affects parental responsibilities, inheritance rights, access to benefits, and a child’s medical history. Attorney Joe VanLandingham brings a background in business law, civil litigation, and corporate litigation to every family law matter, giving him a strategic, whole-case view of how paternity findings ripple into custody, support, and parental rights proceedings.

Step-by-Step Guide to the Paternity Process in Denver

Paternity cases in Denver County are filed at Denver Juvenile Court. To open a case, the petitioner files JDF 1501 (Petition to Determine Parentage) and JDF 1502 (Summons), then personally serves the alleged parent. A petition may be initiated by the child’s mother, the presumed or alleged father, the child through a representative if under 18, or the Colorado Department of Human Services when public assistance is involved.

Admitting or Contesting Paternity

Once served, the alleged parent has options. They may admit parentage by filing JDF 1504 (Admission of Parentage), which waives the right to genetic testing. If paternity is contested, either party may request genetic testing using JDF 1505 (Motion for Genetic Testing, unilateral) or JDF 1506 (Agreement for Genetic Testing, agreed). Under Colorado Revised Statutes §13-25-126, courts may order genetic testing, and a result showing 97% or greater probability of paternity is generally sufficient to establish legal parenthood. DNA results may become available within a few weeks and form the foundation for court decisions on custody, support, and parenting time. If an alleged parent refuses testing, the court may resolve parentage against that party.

Resolution: Voluntary Agreement or Contested Hearing

After results are received, paternity may be established voluntarily if both parties agree, or through a contested hearing if disagreements remain. We guide clients through every stage, from gathering documentation to appearing at hearings, to help avoid common setbacks and pursue a timely resolution.

Legal Implications of Paternity in Colorado

In Colorado, paternity can be legally recognized or legally disproved. Recognized paternity means the man is the child’s legal father with all associated rights and obligations. Disproved paternity means he is not, and if a court makes that finding, there may be no obligation for medical coverage, support, or parental rights. That said, legal responsibilities may persist in certain circumstances, such as prior agreements or a history of providing support.

Presumptions of Paternity Under Colorado Law

Colorado courts apply the Colorado Uniform Parentage Act when considering petitions to establish or challenge paternity. A man is presumed the natural father when a child is born during a marriage, within 300 days of termination of a valid marriage, or when he acknowledges paternity in a document filed with the court or registrar of vital statistics, consents to being named on the birth certificate, or voluntarily signs a written Acknowledgment of Paternity. Colorado law also requires that the presumed father be notified of paternity proceedings, and he has the right to challenge paternity in court.

What an Acknowledgment of Paternity Does & Doesn’t Do

An Acknowledgment of Paternity alone doesn’t establish child support or a parenting time schedule. A court order is required for those. We clarify your obligations, rights, and next steps so both your parental interests and your child’s wellbeing are protected.

Navigating Paternity Laws & Rights in Colorado

Colorado law doesn’t require marriage for a man to be legally acknowledged as a child’s father. Unmarried parents may complete an Acknowledgment of Paternity to formally establish the legal relationship without going to court. Without marriage or a formal acknowledgment, however, paternity must be established before either parent can pursue child support, visitation, or access to parental benefits.

Parenting Time & Decision-Making After Paternity Is Established

Once paternity is recognized, either parent may petition for orders related to legal decision-making and parenting time. Denver courts apply the best-interest-of-the-child standard to decisions about residence, school enrollment, and parental involvement. One meaningful distinction from a custody case: a paternity case filed under C.R.S. Title 19 (Juvenile Code) may result in child support ordered retroactive to the date of the child’s birth, including birthing costs such as doctor and hospital bills. A Title 14 custody case, by contrast, typically runs support only from the date of service.

When Biological Findings Don’t End Legal Responsibility

Even if a man is determined not to be the biological father, legal responsibilities may persist under certain circumstances, such as prior agreements or a support history. If a court finds he is not the legal father, there may be no obligation for medical coverage, support, or parental rights. Our familiarity with local court expectations, including mediation requirements and documentation standards, helps our clients proceed with confidence and avoid complications that could otherwise delay resolution.
