OPINION

Devin R. Maurer (“Devin”) appeals from the trial court’s entry of mutual protective orders against him and his step-mother, Cathleen J. Maurer (“Cathleen”). Devin raises three issues for our review, which we restate as:

I. Whether the trial court erred by entering mutual protective orders with*991out having first determined that at least one allegation in the petition' was proved by a preponderance of the evidence.

II. Whether the trial court erred by entering mutual protective orders.

III. Whether the trial court erred by not appointing a guardian ad litem to protect Devin’s interests.

We reverse and remand.1

Cathleen filed a petition for a protective order against Devin on July 6, 1998. The petition stated that Devin, who was seventeen years old at the time, had verbally threatened Cathleen. An emergency protective order was issued against Devin on July 6, 1998. The court held a hearing on the petition for protective order on July 22,1998. At that hearing, the trial judge refused to hear any evidence from either Cathleen or Devin regarding the allegations in the petition.2 The judge entered mutual protective orders, which ordered both Devin and Cathleen to refrain from “abusing, harassing, disturbing the peace of, or coming about the other,” and “damaging any property of or from coming about the person or place of employment of either party.” Record at 3. Devin appeals from the entry of the mutual protective orders.

I.

Failure to Hear Evidence

Devin contends that the trial court erred by refusing to hear any evidence regarding Cathleen’s petition for the protective order. Protective orders to prevent abuse are governed by Ind.Code §§ 34-26-2-1 to - 17 (1998). Ind.Code § 34-26-2-12 sets forth the hearing requirements for such petitions. Specifically, IC 34-26-2-12 provides, “At the hearing, if at least one .(1) of the allegations described in the petition is proved by a preponderance of the evidence, the court [shall issue a protective order].” Thus, the statute contemplates an evidentiary hearing where the petitioner must prove, by a preponderance of the evidence, that at least one of the allegations in her complaint is true.

Devin argues, and we agree, that the trial court erred by not requiring Cathleen to present evidence to support her petition for a protective order. The statute requires such an evidentiary hearing, and further, requires that at least one allegation be proven by a preponderance of the evidence. In this case, the trial court refused' to allow any evidence to be presented at the hearing. Because the trial court failed to follow the mandate of IC 34-26-2-12, we reverse the entry of the mutual protective orders and remand to the trial court with instructions to hold an evidentiary hearing. At the hearing, the court, must allow Cathleen to present evidence to support her allegation of verbal threats by ■ Devin. After hearing the evidence, if the court finds that the allegation has been proven by a preponderance of the evidence, a protective order may be entered.

II.

Mutuality of Protective Orders

Devin contends that the trial court erred by entering mutual protective orders, when he neither petitioned for a protective order against Cathleen, nor presented evidence in support of such an'order.3 Ind. Code § 34-26-2-10 provides: “A court may not issue a joint or mutual protective order ... under [the relevant portions] of this chapter.” Further, the statute provides that “[i]f both parties allege injury, the parties shall do so by separate motions. The trial court shall review each motion separately.... If the trial court finds cause to grant both motions, the court shall do so by sepa*992rate orders and with specific findings justifying the issuance of each order.” Id. Because Devin did not file a petition for a protective order against Cathleen, and IC 34-26-2-10 specifically prohibits the entry of mutual protective orders, we hold that the trial court erred by entering mutual protective orders.

III.

Guardian Ad Litem

Devin contends that the trial court erred by failing to appoint, or to consider the appointment of, a guardian ad litem to represent his interests at the hearing. Ind. Trial Rule 17(C) provides, in relevant part: “If an infant or incompetent person is not represented, or is not adequately represented, the court shall appoint a guardian ad litem for him.” This court has held that, although it is not mandatory for a trial judge to appoint a guardian ad litem for a minor defendant, “it is mandatory that the trial judge consider the necessity of appointing a guardian ad litem before permitting a minor defendant to proceed without one.” Crayne v. M.K.R.L., 413 N.E.2d 311, 313 (Ind.Ct.App. 1980) (emphasis omitted).

Relying on Crayne, Devin argues that the trial court erred by failing to even consider appointing a guardian ad litem to protect his interests at the hearing on the protective order. However, we need not address this issue, because Devin has turned eighteen in the time since the orders were entered. Furthermore, we hold that the appointment of a guardian ad litem need not be considered on remand, as Devin is no longer a minor.4

Reversed and remanded.
