Paternity & Legal Parentage in Colorado
Legal parentage establishes who the court recognizes as a child’s legal parent and who has standing to seek parental rights and responsibilities. Until parentage is legally established, the court generally cannot enter orders addressing parenting time, decision-making authority, or child support. As a result, parentage is often the first issue that must be resolved before custody-related matters can proceed.
​
Parentage may be established in several ways under Colorado law. A child born to married parents is presumed to be the legal child of both spouses. In other situations, parentage may be established through a Voluntary Acknowledgment of Paternity (VAP), an administrative process, or a court determination based on evidence such as genetic testing. These mechanisms are designed to provide clarity and legal certainty regarding the parent-child relationship.
​
Once legal parentage is established, both parents generally have equal standing before the court. Establishing parentage does not determine custody outcomes on its own; rather, it allows the court to evaluate parenting time and decision-making authority based on the child’s best interests. In disputes involving parentage, courts focus on legal criteria and procedural requirements rather than informal agreements or assumptions between the parties.
Best Interest of the Child Standard
In Colorado, decisions about parenting time and decision-making authority are guided by the “best interest of the child” standard. This standard directs courts to focus on the child’s overall well-being rather than the preferences or grievances of either parent. No single factor controls the outcome; instead, courts weigh multiple considerations based on the specific circumstances of each family.
​
Colorado identifies different factors courts may consider when evaluating a child’s best interests, including:
​
-
The child’s relationship with each parent
-
Each parent’s ability to support and encourage the child’s relationship with the other parent
-
The child’s adjustment to home, school, and community
-
The physical and emotional health of the child and each parent
-
The wishes of the child, when the child is of sufficient maturity to express reasoned preferences
​
Courts also place significant weight on each parent’s past involvement and demonstrated ability to meet the child’s needs. Patterns of cooperation, communication, and decision-making are often more influential than stated intentions. The court’s role is not to reward or punish either parent, but to establish arrangements that support stability, continuity, and the child’s long-term interests.
​
Because best-interest determinations are fact-specific, outcomes can vary even when families appear similar on the surface. Courts retain broad discretion to evaluate the evidence presented and to balance competing considerations. Parenting time and decision-making orders are therefore shaped by how the child’s needs are demonstrated in practice, not by generalized assumptions or formulas.
Parenting Time
Parenting time refers to when a child resides with each parent and how time is shared between households. The court’s focus is on establishing a schedule that supports the child’s stability, safety, and ongoing relationships, rather than on labels or parental entitlements.
Parenting time is determined based on the child’s best interests and the specific circumstances of the family. Courts consider how proposed schedules align with the child’s developmental needs, school obligations, and existing routines. Practical considerations—such as parents’ availability, proximity of residences, and the ability to manage transitions—often carry significant weight in these determinations.
​
Colorado courts do not apply a default parenting schedule or presume that equal time is appropriate in every case. Instead, parenting time arrangements are shaped by the evidence presented and by how each parent has historically participated in the child’s care. The goal is to create a workable structure that minimizes disruption and allows the child to maintain meaningful contact with both parents when appropriate.
​
Once established, parenting time orders are intended to provide predictability and reduce conflict. Courts generally expect parents to follow the schedule as ordered and to address day-to-day flexibility cooperatively. When disagreements arise, the court evaluates whether adjustments are necessary based on the child’s needs rather than parental preference.
Decision Making Responsibility
Decision-making authority determines who has the responsibility to make major decisions affecting a child’s welfare, such as matters related to education, health care, and religious upbringing. This authority is distinct from parenting time and may be allocated separately based on the child’s needs.
​
Colorado courts may allocate decision-making authority jointly or allocate certain areas of decision-making to one parent. The court’s focus is on how decisions have been made historically, each parent’s ability to communicate and cooperate, and whether shared decision-making is workable in practice. When cooperation has been limited or conflict is ongoing, courts may structure decision-making in a way that reduces the potential for future disputes.
​
The allocation of decision-making authority does not reflect a hierarchy between parents. Instead, it is intended to provide clarity and stability in how important decisions are made. Courts evaluate whether the proposed allocation supports the child’s best interests and promotes consistent, timely decision-making rather than ongoing conflict.
​
Once decision-making authority is established, parents are expected to act within the scope of the court’s order. Disagreements are evaluated based on compliance with that order and on whether a parent’s actions serve the child’s interests. Courts generally prioritize arrangements that allow decisions to be made efficiently while maintaining appropriate involvement from both parents.
Court Expectations & Co-Parenting Responsibilities
Courts expect parents to approach parenting time and decision-making with a focus on the child’s needs rather than ongoing conflict between adults. Court orders are designed to create stability and reduce disputes, and judges generally look for conduct that supports consistent cooperation with the other parent’s role in the child’s life.
​
Parents are expected to follow court-ordered schedules and decision-making allocations as written. This includes communicating in a manner that is child-focused, timely, and appropriate, and making reasonable efforts to resolve routine issues without court involvement. Patterns of behavior, such as missed exchanges, poor communication, or repeated conflict, are often more influential than isolated incidents.
​
Courts also pay close attention to a parent’s ability to support the child’s relationship with the other parent. Actions that undermine that relationship, interfere with parenting time, or escalate conflict can raise concerns about a parent’s willingness to prioritize the child’s best interests. In contrast, cooperative conduct and reliable follow-through tend to reflect favorably when courts review parenting arrangements.
​
Because communication issues are a common source of conflict, some parents find it helpful to use structured tools designed to keep exchanges clear, documented, and focused on the child. Practical resources for improving co-parent communication are available in the Parenting Toolkit’s Communication Tools section, which is designed to support court-compliant interactions rather than emotional disputes.
Parenting Plan Overview
A parenting plan is a written framework that outlines how parents will share parenting time and decision-making responsibilities after separation. Its purpose is to provide structure, reduce uncertainty, and support consistency in the child’s daily life.
​
In Colorado, parents are required to submit a parenting plan in cases involving custody or parenting time, whether the plan is agreed upon or contested. The court relies on the plan to understand how parenting time and decision-making authority will function in practice.
​
Parenting plans typically address physical custody schedules, legal custody and decision-making authority, and practical issues such as exchanges, communication, and routines. The level of detail may vary, but the plan should be clear enough to be followed consistently.
​
Once approved by the court, a parenting plan becomes part of the custody order and is enforceable unless it is formally modified.
Creating a Parenting Plan
Creating a parenting plan involves translating custody concepts into a clear, workable structure for parenting time and decision-making. The emphasis is on practicality, how the plan will function day to day and support the child’s stability over time.
​
Parents are generally expected to consider the child’s age, routine, schooling, and developmental needs when developing a plan. Plans that are realistic, specific, and aligned with the child’s existing structure are more likely to be workable and durable.
​
Once adopted, parenting plans are expected to be followed as written unless they are formally modified. Courts typically expect parents to comply with the existing plan even when disagreements arise.
Modifying a Parenting Plan
Parenting plans are not static and may be modified when circumstances change in a way that affects the child’s needs or the plan’s workability. Modification is intended to address meaningful changes, not routine disagreements or short-term challenges.
​
Courts generally require a showing that circumstances have changed since the existing plan was entered and that the proposed modification would better serve the child’s best interests. Changes related to a child’s development, schooling, relocation, or a parent’s availability may be relevant, depending on the situation.
​
Parents are expected to continue following the existing parenting plan unless and until it is formally modified. Unilateral changes, even if well-intended, are typically discouraged and may create enforcement issues.
​
When parents are able to agree on modifications, those changes may be submitted for court approval. When agreement is not possible, the court will evaluate the request based on the child’s needs and the overall stability of the existing arrangement.
Notes for Mothers
Separation and custody proceedings can feel overwhelming, particularly when caring for a child while navigating unfamiliar legal processes. It is common for mothers to carry much of the day-to-day responsibility early on, which can make the prospect of sharing parenting time feel uncertain or emotionally difficult.
​
Courts focus on the child’s long-term well-being and generally expect both parents to have an opportunity to build and maintain a meaningful relationship with the child when it is safe to do so. Supporting that relationship does not diminish a mother’s role; instead, it can help establish stability and predictability for the child over time.
​
Clear communication, consistency with schedules, and a willingness to separate adult conflict from parenting decisions often play a significant role in how custody matters progress. Documenting concerns, staying organized, and focusing on the child’s needs rather than the other parent’s shortcomings can be especially important.
Mothers who feel unsure about how parenting time will evolve may benefit from approaching the process one step at a time. Parenting arrangements often change as children grow, and early schedules do not necessarily define long-term outcomes.
Notes for Fathers
Entering the custody process can be especially challenging for fathers, particularly when legal parentage, early caregiving roles, or limited access to information create uncertainty about where to start. Many fathers assume their involvement will be minimized, even when they are committed to being active and consistent parents.
​
Courts focus on a parent’s demonstrated ability to meet the child’s needs and to support stability over time. Consistency, follow-through, and a willingness to place the child’s well-being above conflict are often more influential than labels or assumptions about parental roles.
​
Establishing routines, honoring schedules, and communicating in a child-focused manner can help reinforce a father’s role as a reliable caregiver. Courts also tend to look favorably on parents who support the child’s relationship with the other parent, even when the co-parenting relationship is strained.
Fathers may find it helpful to approach custody as a long-term process rather than a single outcome. Parenting arrangements often evolve as children grow, and early limitations do not necessarily reflect a parent’s long-term involvement or importance in the child’s life.
Breastfeeding Considerations
Breastfeeding may be considered when establishing parenting time for an infant, but it does not create an automatic preference or eliminate the need to support an ongoing relationship with both parents.
​
Courts may take an infant’s feeding needs, age, and established routines into account when evaluating early parenting time arrangements. These considerations are typically addressed as part of a broader assessment of the child’s developmental needs rather than as a standalone factor.
​
Breastfeeding alone does not prevent the other parent from exercising parenting time. Parenting schedules for infants may involve shorter or more frequent visits initially, with adjustments over time as feeding methods change and the child’s capacity for longer separations increases.
​
As children grow, courts generally expect parenting time arrangements to evolve in a way that supports both the child’s nutritional needs and the development of a meaningful relationship with each parent.
Colorado Family Law & Statutes
Colorado law governing parenting time, decision-making authority, and parenting plans is set out in Title 14 of the Colorado Revised Statutes. These provisions establish the legal framework courts use when allocating parental responsibilities, evaluating a child’s best interests, and reviewing or modifying parenting arrangements.
