A child can be a witness in a Montana domestic violence case. There is no minimum age, and in limited circumstances a child's earlier statements can be used even if the child never takes the stand. Montana also has rules meant to reduce the strain on a child who does testify. This page explains those rules and what parents should and should not do. It is part of our Montana Domestic Violence Guide.

Competency: No Age Cutoff

Rule 601 of the Montana Rules of Evidence starts with a general rule: "Every person is competent to be a witness except as otherwise provided in these rules." A person is disqualified only if the court finds the witness is "incapable of expression concerning the matter so as to be understood by the judge and jury," directly or through an interpreter, or is "incapable of understanding the duty of a witness to tell the truth."

The rule does not mention age. A young child is evaluated like any other witness: can the child communicate what happened, and does the child understand that a witness must tell the truth? The judge decides. Once a child testifies, how much weight to give the testimony is for the judge or jury.

How a Child's Account Enters a Case

In a domestic violence investigation, a child's account can be gathered in several ways:

  • At the scene. Officers may speak with children who were present, and body cameras may record it.
  • On a 911 call, if the child made the call or can be heard on it. See the 911 call as evidence.
  • In a later interview. When there is concern for a child's safety, a child protection investigator, county attorney, or peace officer may interview the child, and the interview may be conducted in the presence of a parent, guardian, or school employee (MCA § 41-3-202(3)). In some communities a trained interviewer conducts and records the interview. If a child protection interview is recorded, an unedited recording must be made available to the family on request, subject to confidentiality limits (MCA § 41-3-202(4)).
  • To other adults, such as a teacher, doctor, counselor, or relative.

Whether any of those statements can be used at trial depends on the hearsay rules.

The Child Hearsay Statute

MCA § 46-16-220 addresses when "otherwise inadmissible hearsay" from a child may be admitted in a criminal proceeding. It names partner or family member assault specifically, and it applies only when every listed condition is met.

ConditionWhat the statute requires
The childUnder 15 years of age, and an alleged victim of or witness to a sexual offense or other crime of violence, including PFMA, that is the subject of the case (subsections (1)(a) and (4))
TrustworthinessThe court finds that the time, content, and circumstances of the statement provide circumstantial guarantees of trustworthiness (1)(b)
UnavailabilityThe child is unavailable as a witness (1)(c)
NeedThe statement is offered as evidence of a material fact and is more probative on the point than any other evidence available through reasonable efforts (1)(d)
NoticeSufficient notice to the other side, including the content of the statement, when, where, and to whom it was made, and the circumstances said to support its reliability (1)(e)

In deciding admissibility the court must consider a long list of matters: the child's age, ability to communicate, ability to tell truth from falsehood, and memory; the relationship between the child and the adult repeating the statement, and whether that adult has a motive to fabricate or distort; whether the statement was spontaneous or followed suggestive questions; whether it was consistent across tellings; how soon after the incident it was made; and whether other evidence corroborates it (MCA § 46-16-220(3)). The court must issue findings of fact and conclusions of law on its reasoning (MCA § 46-16-220(2)).

For a defense lawyer, those factors are a checklist. Who first asked the child what happened, how the questions were worded, and who was in the room all matter. Other hearsay exceptions and the right to confront witnesses can also bear on a child's statement, and they are argued case by case.

Testifying Outside the Defendant's Presence

Montana has a separate procedure for a "child witness," defined as a person 13 or younger when called in a criminal proceeding involving a sexual or violent offense, or under 16 with a developmental disability (MCA § 46-16-226(1)). The listed violent offenses include PFMA under MCA § 45-5-206 and strangulation of a partner or family member under MCA § 45-5-215.

On a motion, the court holds a hearing (MCA §§ 46-16-227 and 46-16-228). The court must order testimony by two-way electronic audio-video communication if it finds "by clear and convincing evidence" that the child is unable to testify in open court in the defendant's presence because of fear caused by the defendant's presence, substantial emotional trauma from testifying in the defendant's presence, or conduct by the defendant or defense attorney that leaves the child unable to continue (MCA § 46-16-229(1)).

When that happens, examination and cross-examination proceed as though the child were in the courtroom, and the defendant must have a means of private, contemporaneous communication with the defense attorney (MCA § 46-16-229(2) and (3)).

Children in the Family Court

A parenting case handles children differently. The judge may interview a child in chambers to learn the child's wishes about residence and parental contact, may permit counsel to be present, and must make a record (MCA § 40-4-214(1)). The court may also appoint a guardian ad litem, whose duties include interviewing or observing the child (MCA § 40-4-205(2)(b)). See allegations raised during a custody case.

What Parents Must Not Do

If you are charged, your release conditions may require you to avoid all contact with "any potential witness who may testify concerning the offense" (MCA § 46-9-108(1)(e)(ii)). A child who was in the house may be one. Read your conditions and ask your lawyer exactly what they mean for your children. Our page on seeing your children with a no contact order covers this.

Even where contact is allowed, these lines hold:

  • Do not ask a child what they remember, what they told anyone, or what they plan to say.
  • Do not tell a child what to say, suggest what "really" happened, or reward or punish any version.
  • Do not ask a child to carry messages to the other parent.
  • Do not show a child police reports, court papers, or messages about the case.

Attempts to influence a witness are a crime in their own right, discussed in witness tampering and contacting the accuser. They also damage a child and harm your position in any parenting case.

Keeping Children Out of the Middle

Whether a child is ever called to testify depends on the other evidence and on decisions by the lawyers and the court. The most useful thing a parent can do is keep the child's life steady, let any counselor do their work without interference, and leave the evidence to the lawyers. For how these issues affect a parenting plan, see PFMA and child custody.
