PER CURIAM.

Defendant wife appeals as of right from a Benzie Circuit Court judgment of divorce awarding plaintiff husband custody of their two minor children.

On appeal, defendant contends that the trial court erred in failing to determine whether an established custodial environment existed, and in failing to cite sufficient factual bases for its conclusions on each of the best interest factors of § 3 of the Child Custody Act, MCL 722.23; MSA 25.312(3).

The parties lived together with their children in New Jersey, where plaintiff was stationed in the military, until their separation in October 1987. When plaintiff was thereafter stationed in California, plaintiff, by agreement of the parties, took Joshua, age 9, with him to California, while Jessie, age 6, remained with defendant. The custody arrangement remained in effect during the pendency of the instant action by stipulation of the parties. At trial, both parties requested permanent custody of both children and requested that the children not be separated.

Our review of child custody cases is de novo. Zuziak v Zuziak, 169 Mich. App. 741, 744; 426 N.W.2d 761 (1988). However, we will affirm custody orders and judgments in a divorce case unless the trial court's factual findings are clearly erroneous. Beason v Beason, 435 Mich. 791, 803; 460 N.W.2d 207 (1990). If the trial court's account of the evidence is plausible in light of the record viewed in its entirety, we may not reverse. Beckett v Beckett, 186 Mich. App. 151, 153; 463 N.W.2d 211 (1990).

A panel of this Court recently held that in original actions involving the determination of custody of children, as opposed to actions for modification or amendment of previous judgments regarding custody, the question whether an established custodial environment existed is irrelevant. Helms v Helms, 185 Mich. App. 680, 682; 462 N.W.2d 812 (1990). However, prior decisions of this Court have held that in original actions in which a temporary custody order exists, the trial court has the responsibility of making a definite finding regarding the issue of custodial environment. See, e.g., DeVries v DeVries, 163 Mich. App. 266, 271; 413 N.W.2d 764 (1987); Schwiesow v Schwiesow, 159 Mich. App. 548, 557; 406 N.W.2d 878 (1987); Curless v Curless, 137 Mich. App. 673, 676-677; 357 N.W.2d 921 (1984). In light of the circumstances of the instant case, in which there was a very substantial period of time between the initial separation and the time of trial, we find the better-reasoned approach to be that of the DeVries line of cases. We believe that a custody arrangement that is the result of a stipulation by the parties is analogous, in terms of intent and effect, to a temporary custody order. In both instances, the court is required to look into the actual circumstances of the case to determine whether an established custodial environment existed. DeVries, supra; Curless, supra. Our concern is not with the reasons behind the custodial environment but with the existence of such an environment. Schwiesow, supra at 557.

Upon de novo review of the evidence presented, we are persuaded that each party clearly established a custodial environment with one of the children in the nearly two-year period during which each party had custody of one child. The trial court's failure to find that there was an established custodial environment in the home of plaintiff for Joshua and in the home of defendant for Jessie was a clear legal error on a major issue. Because we hold that there was clear legal error in failing to find an established custodial environment, it is necessary to determine whether there was clear and convincing evidence to support the custody determination. DeVries, supra at 271; Schwiesow, supra at 557-558. For this reason, we remand this case to the trial court.

II

To determine the best interests of children in custody cases, the trial court must consider the eleven factors of § 3 of the Child Custody Act. The trial court must consider and explicitly state its findings and conclusions with respect to each of these factors. Daniels v Daniels, 165 Mich. App. 726, 730; 418 N.W.2d 924 (1988).

Here, the trial court considered factors (a) through (k) and explained its findings and conclusions with respect to each factor in its opinion. The court found that factors (a) through (e) and (g) favored plaintiff, although factor (d) was a "close question," and that the parties were relatively equal with respect to factors (f), (h), and (j). Regarding factor (k), any other factor, the court noted that it was in the best interests of the children to keep them from being separated as they had been in the past. The court did not take factor (i), preferences of the children, into consideration because it determined that the children were too young to have a preference.

The children were six and nine years of age at the time of the action. One of the eleven factors a trial judge must consider in a custody dispute is the "reasonable preference of the child, if the court deems the child to be of sufficient age to express preference." MCL 722.23(i); MSA 25.312(3) (i). Children of six, and definitely of nine, years of age are old enough to have their preferences given some weight in a custody dispute, especially where there was a prior custody arrangement. Stringer v Vincent, 161 Mich. App. 429, 434; 411 N.W.2d 474 (1987). The trial court's failure to interview the children was error requiring reversal. Id.; Lewis v Lewis, 73 Mich. App. 563; 252 N.W.2d 237 (1977). Where the trial court has failed to analyze the issue of child custody in accord with the mandates of MCL 722.23; MSA 25.312(3) and make reviewable findings of fact, the proper remedy is to remand for a new child custody hearing. Id., at 567. On remand, the trial judge is to consider the preferences of the children when deciding the custody issue.

Reversed and remanded to the trial court for a new child custody hearing.
