Child Support and Custody Rights for Fathers in Colorado

Colorado law gives fathers the same legal standing as mothers in custody, in decision-making, and in parenting time. The system doesn’t automatically favor one parent over the other. What determines the outcome is how prepared you are and how well you understand your rights before you walk into court.

Colorado statutes do not give mothers preferential treatment in custody decisions. Courts are legally required to evaluate both parents on the same criteria of the child’s best interests without any gender-based assumption.

That means a father who is involved, stable, and willing to co-parent has every legal basis to pursue equal or primary custody. The law supports it. At Biondino Law Firm, we see fathers navigate this system every day and the ones who come in informed are the ones who get better outcomes.

Colorado separates custody into two distinct categories. The first is legal decision-making, the authority to make major decisions about your child’s life: education, healthcare, religious upbringing, and extracurricular activities.

Courts can award this jointly to both parents or solely to one. Joint decision-making is common when both parents can communicate reasonably. If your co-parent is attempting to exclude you from these decisions without a court order, that’s a rights violation not just a disagreement.

What you can do:

• Request joint decision-making as part of your parenting plan
• Document instances where major decisions were made without your input
• Petition the court if an existing order is being ignored

The second category is parenting time where your child lives and when. Colorado courts have no presumption favoring equal time, but equal or near-equal schedules are increasingly common when both parents are fit and involved.

Factors the court weighs include:

• Your existing relationship and involvement with the child
• Each parent’s ability to encourage the child’s relationship with the other parent
• The child’s adjustment to home, school, and community
• Any history of domestic violence or substance abuse

One factor that carries significant weight: willingness to facilitate the other parent’s relationship with the child. A parent who actively blocks or undermines contact puts themselves at a disadvantage in court.

If you’re starting from a place of limited parenting time, document your involvement now school pickups, medical appointments, daily routines. Courts respond to patterns, not arguments.

If you were not married to the child’s mother at the time of birth, you have no legal parenting rights until paternity is established. Being listed on the birth certificate helps but is not enough on its own.

Colorado provides two routes:

Voluntary Acknowledgment of Paternity (VAP): Both parents sign the form, typically at the hospital or through the state vital records office. This establishes legal paternity without court involvement.

Court-ordered genetic testing: If paternity is disputed or the mother won’t cooperate, you can petition the district court. Once established, you have the same legal standing as any other father.

Until paternity is formally established, a mother can legally restrict your access and you have no enforceable right to challenge it. This step cannot wait.

Under federal law, both parents have the right to access their child’s educational and medical records regardless of custody arrangements unless a court order specifically restricts it.

If a school or healthcare provider is denying you access without a court order to that effect, they are acting outside the law. You can request records directly and, if necessary, reference your legal right under FERPA (education) and HIPAA (medical).

A parenting plan or support order set today is not permanent. Colorado allows modifications when there is a substantial and continuing change in circumstances, a significant income change, a new parenting schedule, relocation, or a shift in the child’s needs.

Key points:

• Modifications are not retroactive they apply from the date of the request forward
• If your co-parent relocates with the child without court approval, that can be grounds for an emergency motion
• You can request a review of parenting time independent of child support

Don’t wait out a situation that isn’t working. Filing promptly protects your position.

Child support in Colorado is calculated using the Income Shares Model (C.R.S. § 14-10-115), based on both parents’ gross incomes, parenting time, and guideline costs like childcare and health insurance.

Two recent updates matter:

• 2026: The income schedule now extends to $40,000 per month in combined gross income, up from $30,000.
• 2024: The 93-overnight threshold for parenting time credit was eliminated. Every overnight now counts toward reducing the obligation under a unified formula.

Equal parenting time reduces support but doesn’t automatically eliminate it. Income differences and other guideline factors still apply.

If you lose your job or your income drops significantly, file for a modification immediately. In general, reductions don’t apply to the period before a formal request is made.

Court orders whether covering parenting time or child support are legally enforceable. If your co-parent is denying court-ordered parenting time or withholding your child without cause, you have legal recourse:

• File a motion for contempt of court
• Request make-up parenting time
• In serious or repeated cases, seek a modification that reflects the violation

Violations work both ways. If you’re behind on support, enforcement tools wage garnishment, license suspension, tax intercepts apply to you as well. Stay current, and address problems through the court rather than around it.

If you’re facing a custody dispute, a support calculation that doesn’t feel right, or a co-parent who isn’t following a court order, talking to an attorney early makes a real difference. The team at Biondino Law Firm works with Colorado fathers on exactly these issues from establishing paternity to modifying existing orders.

Does Colorado automatically give mothers primary custody? 

No. The court’s only standard is the child’s best interests applied equally to both parents.

Can I get 50/50 custody as a father? 

Yes. Equal parenting time is increasingly common in Colorado when both parents are involved and capable. There’s no legal barrier to it.

What if my co-parent won’t let me see my child? 

If there’s no court order, file for one immediately. If there is an order being violated, file for contempt. Document every denied visit.

Can parenting time and child support be modified later? 

Yes both can be modified with a substantial and continuing change in circumstances. Act quickly; changes generally aren’t applied retroactively.

Do I have rights if I’m not on the birth certificate? 

You have limited rights until paternity is legally established. Establishing paternity is the necessary first step.
