The Best Interests of the Child Standard Under Colorado Law
- Introduction. This memorandum provides a comprehensive summary of the "best interests of the child" standard as applied in Colorado domestic relations proceedings involving parental responsibilities, parenting time, and decision-making authority. The best interests standard is the paramount consideration in all custody and parenting time determinations under Colorado law, with the child's safety, physical health, and emotional well-being taking precedence over all other factors. C.R.S. 14-10-124. This memo examines the statutory framework, applicable legal standards, and case law interpretation governing how Colorado courts apply this standard. Because no specific fact pattern has been provided, this memo offers a general legal analysis rather than application to particular circumstances.
- Legal Standards
- Statutory Framework and Core Principles Colorado courts determine the allocation of parental responsibilities, including parenting time and decision-making responsibilities, in accordance with the best interests of the child, giving paramount consideration to the child's safety and the physical, mental, and emotional conditions and needs of the child. C.R.S. 14-10-124. When allocating parenting time, the court must focus on the child's best interests, with the child's safety always paramount. In re Pawelec, 2024 COA 107, 562 P.3d 106. The overriding purpose of Colorado's Children's Code is to protect the child's welfare and safety, and courts must allocate parental responsibilities accordingly. In re M.W., 2012 COA 162, 292 P.3d 1158. In determining parenting time, the court may make provisions it finds are in the best interests of the child unless it finds, after a hearing, that parenting time by a party would endanger the child's physical health or significantly impair the child's emotional development. C.R.S. 14-10-124. The court must consider all relevant factors when making this determination. In re Pawelec, 2024 COA 107, 562 P.3d 106.
- Statutory Factors for Parenting Time and Decision-Making Colorado law requires courts to consider multiple factors in determining the best interests of the child. These factors include: (1) the wishes of the child's parents as to parenting time; (2) the interaction and interrelationship of the child with his or her parents and any other person who may significantly affect the child's best interests; (3) any report of domestic violence; (4) the child's adjustment to his or her home, school, and community; (5) the ability of the parties to encourage the sharing of love, affection, and contact between the child and the other party; (6) whether the past pattern of involvement of the parties with the child reflects a system of values, time commitment, and mutual support; (7) the physical proximity of the parties to each other as it relates to the practical considerations of parenting time; and (8) the ability of each party to place the needs of the child ahead of his or her own needs. In re Pawelec, 2024 COA 107, 562 P.3d 106. When allocating decision-making responsibility, the court must consider, in addition to the above factors, all relevant factors including credible evidence of the ability of the parties to cooperate and make decisions jointly, whether the past pattern of involvement reflects a system of values that would indicate an ability as mutual decision makers to provide a positive relationship with the child, and whether an allocation of mutual decision-making will promote more frequent contact between the child and each party. C.R.S. 14-10-124.
- Domestic Violence Considerations If a court determines by a preponderance of the evidence that a party has committed domestic violence, child abuse or neglect, or sexual assault that resulted in the conception of a child, it is not in the best interests of the child to allocate mutual decision-making responsibility over the objection of the other party unless the court makes specific findings that mutual decision-making can occur without coercion, intimidation, retaliation, or risk of harm to the abused party or the child. C.R.S. 14-10-124. Courts must consider any finding of domestic violence alongside other statutory factors when determining the allocation of parenting time in the child's best interests. In re Pawelec, 2024 COA 107, 562 P.3d 106. Domestic violence, while a serious and important factor, is not necessarily dispositive in assessing the best interests of the child. In re Pawelec, 2024 COA 107, 562 P.3d 106.
- Modification vs. Restriction of Parenting Time Colorado law distinguishes between modifications and restrictions of parenting time rights. The court may make or modify an order granting or denying parenting time rights whenever such order or modification would serve the best interests of the child. C.R.S. 14-10-129. However, the court shall not restrict a parent's parenting time rights unless it finds that the parenting time would endanger the child's physical health or significantly impair the child's emotional development. In re Marriage of Parr, 240 P.3d 509 (Colo. App. 2010), In re Marriage of Dorworth, 33 P.3d 1260 (Colo. App. 2001). A purely quantitative reduction in parenting time—unaccompanied by qualitative constraints on the manner, location, or environment in which a parent exercises parenting time—cannot amount to a restriction unless the reduction eliminates parenting time altogether. In re Marriage of Dale, 2026 CO 35. A restriction of parenting time rights refers to the complete elimination of any quantity of parenting time or to qualitative constraints on the manner, location, or environment in which a parent exercises parenting time. In re Marriage of Dale, 2026 CO 35, In re Marriage of Dale, 2026 CO 35. Thus, modifications governed by the best-interests standard remain distinct from restrictions governed by the more demanding endanger/impair standard. In re Marriage of Dale, 2026 CO 35. Where a modification would substantially alter parenting time and change the person with whom the child primarily resides, courts must find that circumstances have changed in a way that makes such modification necessary to further the child's best interests. Decker v. Gordon (In re B.R.D.), 2012 COA 63, 280 P.3d 78. The policy behind requiring the more stringent endangerment standard before substantially modifying parenting time and a child's primary residence is to recognize the disruption such a change causes for the child and to promote stability. In re Marriage of Schlundt, 2021 COA 58, 489 P.3d 781.
- Relocation Cases In cases where a party with whom the child resides a majority of the time seeks to relocate with the child to a residence that substantially changes the geographical ties between the child and the other party, the court must take into account all relevant factors in determining whether modification of parenting time is in the best interests of the child. C.R.S. 14-10-129. These factors include: the reasons why the party wishes to relocate; the reasons why the opposing party is objecting to the proposed relocation; the history and quality of each party's relationship with the child since any previous parenting time order; the educational opportunities for the child at the existing location and the proposed new location; the presence or absence of extended family at the existing and proposed locations; any advantages of the child remaining with the primary caregiver; and the anticipated impact of the move on the child. C.R.S. 14-10-129. The party intending to relocate must provide the other party with written notice as soon as practicable of the intent to relocate, the location where the party intends to reside, the reason for the relocation, and a proposed revised parenting time plan. C.R.S. 14-10-129. A court hearing on any modification of parenting time due to an intent to relocate shall be given priority on the court's docket. C.R.S. 14-10-129.
- Modification of Decision-Making Responsibility A court may not modify an order allocating decision-making responsibility unless it finds, upon the basis of facts that have arisen since the prior decree or that were unknown to the court at the time of the prior decree, that a change has occurred in the circumstances of the child or the party to whom decision-making responsibility was allocated and that the modification is necessary to serve the best interests of the child. C.R.S. 14-10-131, Decker v. Gordon (In re B.R.D.), 2012 COA 63, 280 P.3d 78. In applying these standards, the court shall retain the allocation of decision-making responsibility established by the prior decree unless certain conditions are met. C.R.S. 14-10-131. These conditions include: the parties agree to the modification; the child has been integrated into the family of the petitioner with the consent of the other party; there has been a modification in the parenting time order that warrants a modification of decision-making responsibilities; or a party has consistently consented to the other party making individual decisions for the child. C.R.S. 14-10-131. Additionally, the court may modify if the retention of the allocation of decision-making responsibility would endanger the child's physical health or significantly impair the child's emotional development, and the harm likely to be caused by a change of environment is outweighed by the advantage of a change to the child. C.R.S. 14-10-131.
- Judicial Discretion and Findings Requirements The court is not required to make findings on all statutory factors. In re Pawelec, 2024 COA 107, 562 P.3d 106, In re Marriage of Lester, 791 P.2d 1244 (Colo. App. 1990). Findings must be sufficiently explicit, however, to give the reviewing court a clear understanding of the basis of the order. In re Marriage of Lester, 791 P.2d 1244 (Colo. App. 1990). All that is required is an indication that the trial court considered those factors which were pertinent, and that the findings are sufficient to enable the reviewing court to determine the grounds for the trial court's decision and whether the decision was supported by competent evidence. In re Marriage of Lester, 791 P.2d 1244 (Colo. App. 1990). Courts review parenting time determinations for abuse of discretion. In re Pawelec, 2024 COA 107, 562 P.3d 106. A court abuses its discretion if its decision is manifestly arbitrary, unreasonable, or unfair, or if it misapplied the law. In re Pawelec, 2024 COA 107, 562 P.3d 106. In determining the best interests of the child, the court must consider all relevant factors, and applying these criteria, the court must ensure that custody awards serve the child's best interests. In re Marriage of Lampton, 704 P.2d 847 (Colo. 1985).
- Constitutional Protections for Parental Rights Parents possess a fundamental liberty interest in the care, custody, and control of their children. In re Parental Responsibilities of E.S., 264 P.3d 623 (Colo. App. 2011). When a nonparent seeks parental responsibilities over a parent's objection, a court may only allocate primary care to the nonparent upon clear and convincing evidence of special factors justifying this allocation, with express findings. In re Parental Responsibilities of E.S., 264 P.3d 623 (Colo. App. 2011), Glab v. Julian (In re B.J.), 242 P.3d 1128 (Colo. 2010). The constitutional presumption that a fit parent acts in the best interests of the child must be observed throughout any allocation of parental responsibilities proceeding involving non-parent requests for parenting time over a parent's objection. Glab v. Julian (In re B.J.), 242 P.3d 1128 (Colo. 2010). Any such order requires: a presumption in favor of the parental determination; an opportunity for non-parents to rebut this presumption by showing through clear and convincing evidence that the parental determination is not in the child's best interests; and the ultimate burden remains on the non-parents to establish, by clear and convincing evidence, that allocation of parenting time to them is in the child's best interests. Glab v. Julian (In re B.J.), 242 P.3d 1128 (Colo. 2010). The court must make findings identifying the special factors on which the order relies. Glab v. Julian (In re B.J.), 242 P.3d 1128 (Colo. 2010). When a non-parent seeks an allocation of parental responsibilities contrary to the wishes of a parent, the court may not allocate parental responsibilities to the non-parent unless it complies with the requirement to accord special weight to the parent's determination of the best interests of the child. In re Parental Responsibilities of Reese, 227 P.3d 900 (Colo. App. 2010). When determining whether to allocate parental responsibilities to a nonparent under these standards, a court must consider the statutory factors, giving paramount consideration to the physical, mental, and emotional conditions and needs of the child. In re M.W., 2012 COA 162, 292 P.3d 1158.
- Conclusion. Colorado's best interests of the child standard provides courts with a comprehensive, flexible framework for allocating parental responsibilities, parenting time, and decision-making authority. The standard prioritizes the child's safety and overall well-being while considering multiple factors that collectively illuminate what arrangement will best serve each child's unique needs and circumstances. Courts possess broad discretion in weighing statutory factors but must make sufficiently explicit findings to support their determinations. The distinction between modifications and restrictions of parenting time ensures that courts apply appropriate standards based on the nature and severity of concerns about a parent's conduct. Modifications require only a best-interests finding, while restrictions demand proof of endangerment or significant impairment. Relocation cases balance legitimate reasons for geographic moves against the importance of maintaining meaningful relationships with both parents. When non-parents seek parental responsibilities, heightened constitutional protections require clear and convincing evidence and explicit findings of special factors justifying deviation from the presumption favoring parental decision-making. Throughout all proceedings, the child's safety, physical health, and emotional well-being remain paramount, with courts evaluating each case's specific circumstances to determine which allocation of parental responsibilities will best promote the child's welfare and development.
