Plaintiff Betty Irene Johnson appeals from an adverse decree in her action for partition of real estate. Specifically, she alleges trial court was not justified in finding her interest in the disputed property subject to a real estate contract executed between her former husband, defendant Robert Acy Johnson, and defendants James and Linda Tuttle.
The facts from which this case arises are briefly as follows. Betty and Robert Johnson were married on December 24,1974; in February of 1975 they purchased the house and real estate which are the subject of this dispute. They acquired the property as joint tenants under a real estate contract. Sometime in January of 1976, during a period of marital difficulties, both parties *752 moved from the house. On approximately February 9, Robert sold the property on contract to defendants James and Linda Tuttle. Prior to the execution of this latter contract, he had informed the Tuttles that his wife had abandoned any interest in the real estate. This second real estate contract, which identified the seller as “Robert A. Johnson, a single person,” was never signed by Betty. At this same time, Betty commenced a dissolution action; a decree dissolving the parties’ marriage was entered on November 24, 1976. That decree purported to award both Robert and Betty a one-half interest in the disputed real estate.
In September of 1977, Betty initiated the present action, asking that the property be partitioned and that the Tuttles’ interest be declared secondary to her own. Following trial in June of 1979, the court orally announced its intent to rule in favor of defendants. In its written findings and conclusions filed in October, trial court determined that Betty, “at the time she moved out of the premises did advise her then husband, Robert Acy Johnson, that she had no interest in carrying on the contract for the property or in keeping it.” Based on findings that Robert had been authorized by Betty to dispose of the property, and that she was estopped from denying the Tuttles’ contract due to her knowledge of improvements and payments they made and her failure to act on that knowledge, the court concluded that the “equitable title, subject to the outstanding legal title [held by the Johnsons’ vendor], should be vested in both [Betty and Robert] subject to the valid contract with [the Tuttles]”. Trial court further provided that Betty join Robert in executing a deed to be held in escrow pending the completion of the second contract, and that the “excess payments” on the Johnson-Tuttle contract (the Johnsons’ profit) should be shared equally between Robert and Betty.
Because this action is in equity, we find the facts de novo. As such, while we are not bound by the factual findings of the trial court, we do give them weight, “especially when considering the credibility of witnesses.” Iowa R.App.P. 14(f)(7).
I. Waiver of the right to appeal The initial issue we must confront in this case concerns Betty’s alleged waiver of her right to appeal. This question arises on a motion to dismiss filed in this court by the Tuttles. See Iowa R.App.P. 23(a).
Immediately preceding the commencement of her partition action, Betty paid real estate taxes in the amount of $60.26 and a $71.60 insurance payment in connection with the disputed property. In orally announcing its intention to find in favor of defendants, trial court had stated that Betty should be reimbursed by the Tuttles for these expenditures; this provision was subsequently incorporated in its written decree filed on October 10, 1979. In September, prior to the filing of trial court’s written decree but following the oral pronouncement, the Tuttles’ attorney maiied to Betty’s attorney a check in the sum of $131.86, purportedly representing the amount she was to be reimbursed. This check was in turn forwarded to Betty, who cashed it during the pendency of this appeal. On March 10,1980, the Tuttles filed the motion to dismiss alleging that Betty, in cashing the check, had accepted the benefits of the decree and thereby waived her right to appeal. We ordered that the motion be submitted with the merits of the case.
The Tuttles’ motion is predicated upon the general principle that a party who accepts “material and substantial benefits under a judgment or decree may not ordinarily challenge the provisions under which such benefits are awarded.”
In re Marriage of Abild,
In this case, Betty and the Tuttles disagree as to the purpose of the check and the circumstances surrounding its endorsement. The trial record is devoid of any evidence bearing on this issue. The information before us is limited to the opposing contentions of the parties contained in the motion and the resistance thereto, an affidavit accompanying each, the briefs filed in this court and the cancelled check, offered at the oral submission of this appeal. A motion to dismiss pursuant to Iowa R.App.P. 23(a) or a resistance thereto should be supported by references to attached copies of relevant portions of the trial court record, affidavits or stipulations of facts.
See
Iowa R.App.P. 22(c). In rare circumstances, when the facts relevant to a motion to dismiss cannot be shown in any other manner, application should be made to this court for the appointment of a commissioner to receive evidence and propose findings of fact upon which this court can base its findings and conclusions in relation to the motion to dismiss.

II. Merits of plaintiff’s appeal. As noted at the outset, Betty contends trial court was not justified in concluding that her interest in the disputed property was subject to the real estate contract executed by her former husband and the Tuttles. The determinative questions here are whether, under the record in this case, Robert was justified in selling the real estate without Betty joining in the conveyance, and whether she may now assert an equitable interest in the realty superior to that of the Tuttles.
Betty initially asserts that the decree dissolving the marriage between herself and Robert, which awarded an undivided one-half interest in the disputed property to each, is res judicata with respect to the property rights and interests of these parties. We note, however, that the question of the effect of the real estate contract between Robert and the Tuttles was never raised in the dissolution proceedings, even though Betty’s attorney in that proceeding was aware of the sale. Furthermore, neither Robert nor his attorney was present when the hearing on the petition for dissolution was conducted. Consequently, the decree did not constitute a final adjudication with regard to the issues raised in this action. Similarly, Betty’s contention that the property division contained in the dissolution decree may not be modified by a subsequent proceeding is misplaced here. We are not presented in this case with the attempted, subsequent modification of the property division,
see, e.g., In re Marriage of Johnson,
We have previously applied the doctrine of estoppel to interests in real property wherever necessary to prevent injustice.
See, e.g., In re Estate of McAllister,
We note initially that the traditional elements of equitable estoppel, which must be demonstrated by clear, convincing and satisfactory evidence, have been established by the facts of this case. These elements are generally delineated as (1) a false representation or concealment of material facts; (2) a lack of knowledge of the true facts on the part of the actor; (3) the intention that it be acted upon; and (4) reliance thereon by the party to whom made, to his prejudice and injury.
See, e. g., Farmers & Mechanics Savings Bank v. Campbell,
Moreover, the record in addition clearly demonstrates that Betty knew or should have known of the sale of the disputed property to the Tuttles for some time prior to the commencement of her partition action. Betty was aware that the payments due under the contract which she and Robert had executed were always made, yet she made no effort to inquire as to who or under what circumstances those payments were being made. Further, balances owed by Robert and Betty on both a sewer installation and washer-dryer for the house were taken over and paid by the Tuttles. Most importantly, Betty herself testified that she knew of the sale to the Tuttles by the end of spring in 1976; the record indicates, however, that she made no effort known to these defendants to assert her interest until the filing of this partition action in September of 1977. Under these circumstances, we *755 find Betty’s silence and inaction with respect to her equitable interest in the realty are such that she cannot now claim that her interest is not subject to the real estate contract executed between Robert and the Tuttles.
Our foregoing conclusion notwithstanding, Betty will still receive for her interest one-half of the profit derived from the contract with the Tuttles. While we do not approve of Robert’s representing himself as single when he entered the contract with the Tuttles, we are satisfied that trial court reached an equitable solution in this case, and its decree is affirmed.
AFFIRMED.
