Parental Alienation in Colorado: Evidence, Remedies, and Custody Shifts

Parental alienation in Colorado is handled not through a dedicated statute but through the best-interests-of-the-child framework in C.R.S. § 14-10-124, which requires judges to weigh each parent’s willingness to foster the child’s relationship with the other parent.¹ A parent who systematically turns a child against the other parent risks losing parenting time, decision-making authority, or primary residency. You enforce that risk by documenting the behavior and filing a verified motion asking the court to intervene.

How Colorado Law Treats Alienating Behavior

Colorado does not recognize “parental alienation syndrome” as a medical or legal diagnosis. What the statute does recognize is behavior. Section 14-10-124 directs the court to consider each parent’s ability to encourage the sharing of love, affection, and contact between the child and the other parent. A parent who badmouths the other parent, blocks phone calls, intercepts messages, withholds school or medical information, or manipulates the child’s feelings scores poorly on that factor, and the score affects how a judge allocates parenting time and decision-making.¹

The statute’s legislative declaration backs this up by stating that children benefit from frequent and continuing contact with both parents after separation. You don’t need a psychologist to testify that a syndrome exists. You need evidence that one parent is undermining the child’s relationship with the other.

One important carve-out: if a parent limits contact to protect the child from witnessing domestic violence or from being a victim of abuse or neglect, those protective actions cannot be held against that parent under the relationship-fostering factor.¹ If you are accused of alienation and your conduct was driven by legitimate safety concerns, ask your attorney to raise subsection (1.5)(a)(VI) directly, and bring the documentation that supports it.

Alienation Is Not the Same as Estrangement

Not every child who rejects a parent has been alienated. A child sometimes pulls away because of the rejected parent’s own conduct, including abuse, neglect, substance use, or chronic conflict that frightens them. Courts call that estrangement, and it leads to a very different outcome. With alienation, the court tries to repair the relationship and may shift custody away from the manipulating parent. With estrangement, the court protects the child, which usually means restricting the rejected parent’s time rather than expanding it.

The line often turns on whether the child’s rejection is proportional to what actually happened. A child who suddenly refuses all contact with a parent they previously had a warm relationship with, and who can only parrot vague complaints that echo the other parent’s language, looks very different from a child whose fear traces to specific, documented incidents. Judges lean on expert evaluations to tell these apart.

Evidence That Changes a Judge’s Mind

Courts appoint two kinds of professionals to examine the family dynamic: Child and Family Investigators (CFIs) and Parental Responsibility Evaluators (PREs). A CFI interviews both parents and the child, observes interactions, reviews records, and produces a report with recommendations.² A PRE does similar work in greater depth, usually with psychological testing and more extensive interviews.³

What these evaluators look for is a pattern, not a single incident. Build your evidence the same way. Keep a dated log of each denied or interfered-with parenting exchange. Save text messages and emails. Note when the other parent withholds information about doctor’s appointments or school events, or coaches the child to refuse visits. Organized, timestamped records are what separate a winning motion from a frustrating hearing.

Remedies the Court Can Order

When a parent violates a parenting time order, C.R.S. § 14-10-129.5 gives judges a menu of responses. After a hearing, the court can issue one or more of the following:⁴

Makeup parenting time of the same type and duration as what was denied, provided within six months (or one year for holidays that can’t be replicated within six months).
A parenting education program for one or both parents, at the noncomplying parent’s expense.
Family counseling at the violating parent’s expense, which in severe cases takes the form of reunification therapy with a licensed professional specializing in damaged parent-child bonds.
Civil fines of up to $100 per incident of denied parenting time.
A bond or security posted by the violating parent to guarantee future compliance.
A contempt citation, which under Colorado’s general contempt rules can carry fines and up to six months in jail.
A hearing to revisit the entire custody arrangement.

The process moves quickly once a verified motion is filed. Within 35 days of receiving it, the court must decide whether to deny the motion, set a hearing, or order mediation. If mediation is ordered, the parties must report back within 63 days.⁴

When Alienation Can Shift Custody

Sustained alienating behavior can trigger a full modification of custody under C.R.S. § 14-10-129. The statute allows the court to change parenting time and even shift primary residency if the child’s current environment endangers their physical health or significantly impairs their emotional development.⁵ Colorado courts have treated sustained alienation as the kind of emotional harm that meets that threshold.

Any order restricting a parent’s time must include specific factual findings. The judge has to articulate exactly what the alienating parent did and how it harmed the child. Vague allegations without supporting evidence from a CFI or PRE report, text messages, or credible testimony rarely clear that bar.

Decision-making authority over education, healthcare, and extracurricular activities can also be reassigned. Judges look for the parent most likely to support the child’s relationship with both households. A parent found to be sabotaging that relationship is, by definition, the weaker candidate for sole decision-making power.

How to File the Motion

To enforce a parenting time order or address alienating behavior, file a Verified Motion Concerning Parenting Time Disputes using form JDF 1418, available through the Colorado Judicial Branch self-help portal.⁶ If you are seeking a contempt finding specifically, use JDF 1816 (Verified Motion and Affidavit for Citation for Contempt of Court) instead. The wrong form creates delays, so pick the remedy first.

The motion needs your case number and a clear, specific description of each violation: dates, times, and what happened. Attach your supporting evidence, including text messages, emails, and the chronological log you’ve been keeping. “Verified” means you sign it under penalty of perjury, so your facts need to be accurate.

File with the clerk of the court in the county where your original custody case was decided. Filing fees vary by motion type. A motion to modify filed after the first 60 days of an order costs $105; other filing types carry different fees, and Colorado increased many court fees effective January 2025, so check the current schedule before filing.⁷ After filing, formally serve the other parent with a copy of the motion and the summons, then file the return of service form with the court to prove service was completed.

Child Support After a Custody Shift

If the court shifts primary residency, your child support order almost always needs to be recalculated. A change in the number of overnight visits is an explicit ground for review, as is a change in either parent’s income or in the costs of raising the child.⁸

To request a review, submit a written request to the county child support office handling your case, along with an Income and Expense Affidavit and documentation of the reason for the change. The review can take up to six months, and the resulting order may increase, decrease, or leave support unchanged.⁸ File promptly. Changes generally take effect from the date of filing, not retroactively, and the old support amount does not adjust automatically when custody shifts.

If You Disagree With the Ruling

You have 49 days from the date of the final written order to file an appeal. An additional 35 days is available if you show good cause for the delay, but extensions are rarely granted, and once the window closes the opportunity is gone.⁹

The appeal filing fee is $223 unless the court grants a waiver, and you must also post a $250 appeal cost bond with the District Court. The appellate court does not hear new evidence or re-weigh testimony; it reviews only whether the trial court’s orders were reasonable given the record.⁹ If a Magistrate issued the original order and you were required to file a Petition for Magistrate Review, the appeals court will only consider issues you raised in that petition. Skipping Magistrate Review means forfeiting those issues on appeal.
