The opinion of the Court is delivered by
In conjunction with their impending divorce, George Guliadis and Maria Confortó (formerly Guliadis) entered into a property settlement agreement. The agreement included a lease that was executed separately. When the couple divorced, the property settlement agreement and accompanying lease were incorporated into the final divorce judgment. Five years after the divorce judgment, Confortó sought reformation of the lease, contending that it was based on mutual mistake and was unfair as written. This cáse requires the Court to determine the *320 standards that govern the enforceability of a lease executed as part of a property settlement agreement incorporated in a judgment of divorce. That determination requires consideration of whether those standards should be resolved by principles of matrimonial law applicable to the modification of judgments of divorce or principles of contract law applicable to the reformation of lease agreements.
I
Plaintiff Conforti and defendant Guliadis were married on December 30, 1979. Together they owned and operated a business, the Garden State Deli, at 1207 Anderson Avenue in Fort Lee. The couple also owned the building in which the business was located, a two-story structure with retail space at street level and two. apartments on the second floor. The couple’s only child, a daughter, was born just over three years after they were married.
Conforti and Guliadis were divorced by a judgment entered on June 25, 1984. Incorporated into the final divorce judgment was a property settlement agreement in which each party waived any alimony claim against the other. Pursuant to the agreement, Conforti transferred her interest in the building to Guliadis and Guliadis transferred his interest in the delicatessen to Conforti. In addition, Conforti paid $20,000 to Guliadis, apparently because the delicatessen was worth more than the building which housed it. Custody of the daughter was awarded to Conforti, and, as stipulated in the property settlement agreement, Guliadis pays twenty-five dollars per week in child support.
Paragraph 3C of the property settlement agreement provided that Guliadis would lease the retail space occupied by the delicatessen to Conforti for fifteen years, and that Conforti would receive a five-year option to renew. The agreement and the accompanying lease were signed on the same day.
*321 A rider to the lease provided that Guliadis could terminate the lease if he sold the building. The rider also gave Confortó the right of first refusal. The rider provision stated:
2. It is further agreed that this Lease shall be subject to termination at any time in the event that Lessor shall desire to sell the demised premises and shall have a bona fide offer for the purchase thereof. In such event Lessee shall have the option for a period of_tion [sic] from Lessor to meet the terms and conditions of such offer. If Lessee fails to accept the terms and conditions of sale during the said_day period, [sic] the option shall be of no further force and Lessor shall be free to sell the premises to third persons.
On May 19, 1989, approximately five years after the parties signed the property settlement agreement and the accompanying lease, Guliadis’s attorney sent Confortó a letter informing her that his client had received a bona fide offer of $850,000 to purchase the building. The letter warned Confortó that if she failed to execute her right of first refusal, Guliadis would sell the building and terminate her lease.
On August 24, 1989, Confortó filed a petition and order to show cause in the Chancery Division, Family Part. She sought, among other things, deletion of the provision in the rider that purports to terminate the lease upon sale of the building. She alleged that the termination provision was inconsistent with the property settlement agreement as a whole, that it was inserted as a result of mutual mistake, and that enforcing it would be unfair. In the alternative, she claimed that if Guliadis actually had intended the provision to read as it did, he induced her to agree to it through fraud. Guliadis filed a certification which denied Conforti’s allegations. According to Guliadis, the termination provision accorded with the parties’ intent, Confortó understood the provision and its implications, and the provision was consistent with the property settlement agreement read as a single unit.
The trial court denied Conforti’s application for a plenary hearing. It declared that in the event that she failed to exercise her right of first refusal within sixty days, Guliadis would have the right to sell the building and terminate the lease. The court viewed Conforti’s application as both a motion *322 pursuant to Rule 4:50-l(f) for relief from judgment of divorce and as a complaint for equitable reformation of the lease. It ruled that relief would not be granted under Rule 4:50 — 1(f) because the five years that had elapsed since the lease was executed were more than the “reasonable time” permitted under the Rule. The court denied Confortó a plenary hearing on her equitable claim because her certifications did not present the “clear and convincing proof” required for equitable reformation. The court concluded that the sufficiency of Conforti’s proofs could be assessed solely on the basis of the parties’ certifications and that no further taking of evidence was needed.
Confortó appealed from the trial court’s denial of a plenary hearing and the Appellate Division reversed. 245

Guliadis appealed as of right on the issue of whether a full evidentiary hearing is required to decide a motion for equitable *323 reformation of a lease that was executed as part of a property settlement agreement and which is incorporated into a final divorce judgment. We now hold that a hearing is required in those circumstances and that the adjudication of that issue should be undertaken by the Family Part of the Chancery Division.

The equitable authority of courts to modify property distribution, alimony, and support orders issued in divorce cases is well established. We have recognized that marital property is distinctive,

In this case, although plaintiff seeks modification of what appears to be a standard lease for retail space, the lease was but one component of a much broader agreement encompassing a host of domestic issues that arose when Confortó and Guliadis ended their marriage. Consequently the lease must be viewed within the framework of the judicially-sanctioned alloca
*324
tion of marital property and cannot be viewed merely as a conventional property transaction. Equitable distribution of marital property is “intimately related to support,” and “[t]he power to distribute property equitably should be exercised to relieve the strain of total reliance on support payments for financial security.”

Conforti’s complaint fairly raises the issues of whether the challenged provision in the rider of the lease can be reconciled with the dominant intent of the property settlement agreement and whether its enforcement would be fair and equitable. Thus, it is of some significance that Conforti paid $20,000 for the delicatessen, generating the inference that both parties regarded the building as having little value. Although Conforti contends that the rider provision as such was not intended to be a part of the lease even though included, her claims suggest that if it was intentionally included, it could not have been understood by the parties to pose an insurmountable barrier to continuing her business. Conforti asserts that it is now impossible for her to acquire the building or to relocate elsewhere in the neighborhood, and that she will be put out of business and unable to make a living if her former husband sells the building and her lease is terminated pursuant to its literal terms. Further, if forced to move elsewhere, she would lose the good will she has built up through years of operation at one location. In sum, Conforti’s claim, fairly read, indicates that the parties never contemplated that the lease would work a forfeiture of her leasehold interest, and, in light of principles of fairness and equity, that the rider’s provision should not be enforced to *326 deprive her of the primary source of support of herself and her daughter.
The disputed facts also may implicate issues concerning alimony and support. Divorce orders that relate to alimony and support generally can be modified in response to changed circumstances, “regardless of their source,” and regardless of their foreseeability.

The property-settlement agreement between Confortó and Guliadis subsumed all alimony and support obligations with the exception of nominal monthly support for the daughter. Under some circumstances, the interrelationship between the distribution of marital assets and alimony and support obligations can be significant in resolving the enforceability of property-settlement agreements.

Confortó also claims that if the contract were interpreted as contemplating the possibility that she be left without a place to run her delicatessen, then the contract either was based on mutual mistake or was executed through fraud. The Appellate Division mistakenly states that Confortó claims that she “signed the lease in its present form as a result of mistake on her part and fraud on his.” 245

In evaluating claims of mutual mistake and fraud, a court necessarily must look beyond the four corners of the contract.

403,
Conforti’s claims fairly pose factual issues relating to the intent of the parties in reaching their property settlement agreement, the degree to which strict enforcement of the rider provision would be inequitable and unfair, and whether the property settlement agreement implicates concerns of alimony and child support, as well as the existence of mutual mistake and fraud. Her certifications of fact should not be read restrictively or literally to determine whether alone they spell out a claim for relief, nor should their probative worth be neutralized or discounted by the opposing certifications. Rather, they must be examined with an appreciation that if supported by competent evidence they would establish a prima facie cause of action. We thus agree with the majority of the Appellate Division that the material facts presented by the conflicting affidavits are sufficiently in dispute to warrant a plenary *329 hearing. We are satisfied, moreover, that all of the issues raised by the claims and defenses of the parties are principally related to a matrimonial cause of action.
Ill
We conclude that plaintiff has presented an equitable claim for reformation of the lease raising factual issues that should be adjudicated at a hearing and, further, that the claim is made in the context of the judgment of divorce incorporating the property-settlement agreement of the parties. Accordingly, we affirm and modify the judgment below and remand the case to the Family Part of the Chancery Division.
Opposed — none.
