Opinion

The defendant, Aniruddha Desh-pande, appeals from the judgment of the trial court rendered in connection with the underlying dissolution action in which the court entered an order for child support1 and from the judgment of the trial court denying his motions for modification of the child support order. The defendant claims that the court (1) improperly entered a child support order without finding the presumptive amount of child support due under the child support and arrearage guidelines2 or explaining the reasons for any deviation from the presumptive amount, as required by General Statutes § 46b-215b (a); (2) improperly refused to allow him to introduce evidence pertaining to the financial circumstances of the plaintiff, Judith Deshpande, in order to establish grounds for a modification of the child support order; (3) improperly refused to allow him to present evidence *473regarding certain factors3 supporting a deviation from the presumptive child support amount under the guidelines; and (4) erroneously stated in its memorandum of decision that a hearing was held to address his two motions for modification. We agree with the defendant’s first claim and, accordingly, reverse the judgment of the court.4

The following undisputed facts and procedural history are relevant to our resolution of this appeal. The parties married on September 6, 1991. They have three children, all of whom had yet to reach the age of twenty-three at the time of the court’s judgment. The plaintiff filed a marital dissolution complaint on November 24, 2009. On May 13, 2010, the parties filed an agreement in which the defendant agreed to pay to the plaintiff $322 per week in child support. The court, Markle, J., approved the agreement and made it an order of the court. On November 4, 2010, the parties filed an agreement modifying the May 13, 2010 agreement. The defendant again agreed to pay to the plaintiff $322 per week in child support. The court, Abery-Wetstone, J., approved the modified agreement and made it an order of the court. In approving each agreement, the court did not make any finding regarding the presumptive amount of child support due under the child support guidelines nor did it make a finding regarding any deviation from the guidelines.5 The defendant did not appeal from the court’s November 4, 2010 order.

*474On January 10, 2011, the defendant filed a motion to modify the court’s November 4, 2010 order. In the motion, the defendant requested that the court decrease the amount of child support to be paid. On January 27, 2011, the court, Hon. James G. Kenefick, Jr., judge trial referee, ordered the defendant’s motion for modification to be addressed at the final hearing on the divorce. That trial was held on February 7 and 8, 2011. At trial, the court, Gould, J., denied the defendant’s January 10, 2011 motion for modification. In rendering its judgment of dissolution, the court ordered the defendant to continue paying $322 per week in child support. Neither at trial nor in its judgment of dissolution did the court make any finding regarding the presumptive amount of child support due under the statutory child support guidelines nor did it make a finding regarding a deviation from the guidelines.

On February 14, 2011, the defendant filed a second motion to modify the court’s child support order. A hearing on the motion was held on March 24, 2011. At the conclusion of the hearing, the court, Gould, J., denied the defendant’s motion. On March 29, 2011, the defendant filed a motion for reargument and reconsideration of the corut’s denial of his motion for modification, which the court denied on March 31, 2011. On April 15, 2011, the defendant appealed from the March 24, 2011 judgment of the court denying his February 14, 2011 motion to modify the court’s child support order and from the February 8, 2011 judgment of dissolution with respect to the order of child support and the denial of his first motion for modification.6

*475The defendant claims that the court erred by entering a child support order without making an initial finding that specified the presumptive amount of his child support obligation under the statutory child support guidelines as mandated by General Statutes § 46b-215b (a). Further, the defendant claims that, to the extent that the court’s child support order deviated from the presumptive amount, the court failed to make any findings explaining the reasons for its deviation.7 We agree.

We first set forth the standard of review and applicable law governing the defendant’s claim. “The well settled standard of review in domestic relations cases is that this court will not disturb trial court orders unless the trial court has abused its legal discretion or its findings have no reasonable basis in the facts. ... In determining whether a trial court has abused its broad discretion in domestic relations matters, we allow every *476reasonable presumption in favor of the correctness of its action. . . . Notwithstanding the great deference accorded the trial court in dissolution proceedings, a trial court’s ruling . . . may be reversed if, in the exercise of its discretion, the trial court applies the wrong standard of law.” (Citations omitted; internal quotation marks omitted.)

Section 46b-215b (a) provides: “The child support and arrearage guidelines issued pursuant to section 46b-215a, adopted as regulations pursuant to section 46b-215c, and in effect on the date of the support determination shall be considered in all determinations of child support award amounts, including any current support, health care coverage, child care contribution and past-due support amounts, and payment on arrearages and past-due support within the state. In all such determinations, there shall be a rebuttable presumption that the amount of such awards which resulted from the application of such guidelines is the amount to be ordered. A specific finding on the record that the application of the guidelines would be inequitable or inappropriate in a particular case, as determined under the deviation criteria established by the Commission for Child Support Guidelines under section 46b-215a,8 shall be required in order to rebut the presumption in such case.” (Emphasis added.)

“The guidelines incorporate these statutory rules and contain a schedule for calculating the basic child support obligation, which is based on the number of children in the family and the combined net weekly income of the parents. . . . Consistent with ... § 46b-215b (a), the guidelines provide that the support amounts calculated thereunder are the correct amounts to be *477ordered by the court unless rebutted by a specific finding on the record that the presumptive support amount would be inequitable or inappropriate. . . . The finding must include a statement of the presumptive support amount and explain how application of the deviation criteria justifies the variance. . . . [Our Supreme Court] has stated that the reason why a trial court must make an on-the-record finding of the presumptive support amount before applying the deviation criteria is to facilitate appellate review in those cases in which the trial court finds that a deviation is justified. ... In other words, the finding will enable an appellate court to compare the ultimate order with the guideline amount and make a more informed decision on a claim that the amount of the deviation, rather than the fact of a deviation, constituted an abuse of discretion.” (Citations omitted; emphasis in original; internal quotation marks omitted.) Kiniry v. Kiniry, 299 Conn. 308, 319-20, 9 A.3d 708 (2010); O'Brien v. O'Brien, 138 Conn. App. 544, 550, 53 A.3d 1039 (2012).

Section 46b-215a-3 (a) of the Regulations of Connecticut State Agencies provides in relevant part: “An agreement of the parties may be sufficient to rebut the presumption when such finding cites one or more deviation criteria, which may include other equitable factors, to support such agreement. Any such finding shall state the amount that would have been required under such sections and include a factual finding to justify the variance. Only the deviation criteria stated in the lettered subparagraphs of subdivisions (1) to (6), inclusive, of subsection (b) of this section, and indicated by the check boxes in section VII of the worksheet, shall establish sufficient bases for such findings.” In Tuckman v. Tuckman, 308 Conn. 194, 61 A.3d 449 (2013), our Supreme Court recently stated that “the applicable statutes, as well as the guidelines, provide *478that all child support awards must be made in accordance with the principles established therein to ensure that such awards promote equity, uniformity and consistency for children at all income levels.” (Emphasis altered; internal quotation marks omitted.) Id., 206.

It is evident from our thorough review of the record that the court failed to make any findings regarding the presumptive amount of child support under the guidelines or regarding a deviation from that amount. Although the May 13, 2010 and November 4, 2010 agreements by the parties—both of which were approved by the court and incorporated into its orders—specified a child support amount of $322 per week, neither agreement stated the presumptive amount of support that should have been calculated in accordance with the child support guidelines. As previously noted, an agreement of the parties may be sufficient to rebut the presumption that the support amount calculated under the guidelines is the correct amount; however, the court must still make such a finding, cite one or more deviation criteria to support the agreement, state the amount that would have been required under such sections and make a factual finding to justify the variance. Regs., Conn. State Agencies § 46b-215a-3. Here, the court made no such findings.

At no time during the trial on February 7 and 8, 2011, did the court state the presumptive amount of support due under the guidelines or make any reference whatsoever to the guidelines. Instead, the court stated only that the $322 per week in child support on which the parties previously agreed would continue. Similarly, the court failed to make any reference to the presumptive amount in its February 8, 2011 judgment containing its final order requiring the defendant to continue to pay $322 in child support.9 Because the court failed to specify the presumptive amount or make any findings *479regarding a deviation from that amount, we can only speculate as to the amount, whether the court’s child support order deviated from that amount and, to the extent that there was a deviation, whether the circumstances of this case justified a variance from the presumptive amount based on the court’s application of the deviation criteria. Therefore, we conclude that the court abused its discretion by rendering a child support order without first articulating the presumptive amount due under the child support guidelines or explaining any deviation from that amount.

The judgment is reversed only with respect to the order of child support and the case is remanded for further proceedings consistent with this opinion.

In this opinion BISHOP, J., concurred.

dissenting. I do not disagree with the majority’s legal analysis with respect to a trial court’s obligation to make a factual finding regarding the presumptive amount of child support due under the child support and arrearage guidelines prior to entering a child support order. I respectfully dissent, however, because I believe this court should not reach the merits of a collateral attack on a dissolution judgment that was not timely appealed. For that reason, I would affirm the judgment of the trial court.

With respect to the majority’s statement of the facts, I would emphasize the fact that the plaintiff, Judith Deshpande, and the defendant, Aniruddha Deshpande, agreed on a specified weekly amount for child support, based on their earning capacities, on November 4,2010.1 *480The agreement of the parties was reached with the assistance of the family relations office and was signed by the plaintiff, the defendant and their respective attorneys. The court, Abery-Wetstone, J., did not make a finding of the presumptive amount for child support or indicate whether there were any deviation criteria when it accepted the parties’ agreement and made it an order of the court.

Subsequently, after a two day trial, a judgment of dissolution was rendered by the court, Gould, J., on February 8, 2011. At that time, the court ordered the defendant to continue paying the amount of child support that had been agreed upon by the parties, and made an order of the court, as requested by the parties, in November, 2010. The defendant represented himself at the dissolution trial and now was dissatisfied with that amount.2 He requested that the court decrease his child support obligation. The court told him that either party could file a postjudgment motion for modification. When rendering the dissolution judgment, the court did not make a finding of the presumptive amount for child support or indicate whether there were any deviation criteria when it entered the agreed upon, earning capacity child support order, although there were two child support guideline worksheets in the file. The self-represented defendant did not appeal timely from the judgment of dissolution in which the pendente lite child support order had become a final order.

*481Less than one week after the judgment of dissolution was rendered, the defendant filed a motion to modify the court’s child support order. The court denied the defendant’s postjudgment motion after a hearing on March 24, 2011, on the ground that he had failed to demonstrate a substantial change of circumstances. After the court’s denial of the defendant’s motion for reargument and reconsideration, which had been filed pursuant to Practice Book § 11-11, the defendant timely appealed from the court’s judgment denying his February 14, 2011 motion to modify the child support order. The defendant again was represented by counsel when he filed his appeal on April 15, 2011. The appeal form noted that the defendant, in addition to appealing from the denial of the motion for modification of child support, was appealing from “the judgment.” The judgment of dissolution, however, was rendered on February 8, 2011, and any appeal from that judgment should have been filed on or before February 28, 2011. See Practice Book § 63-1.

The plaintiff did not file a motion to dismiss that portion of the appeal challenging the judgment of dissolution. See Practice Book § 66-8. By motion dated May 10, 2011, the defendant requested that the trial court “articulate the factual and legal basis of its rulings on February 8 and March 24, 2011, denying [the] defendant’s motions for modification of child support.” The plaintiff timely filed an objection, claiming, inter alia, that “[n] either the appeal nor the articulation was filed within the 20-day appeal period from the judgment on February 8, 2011.” The plaintiff additionally raised the issue of the untimeliness of the appeal with respect to the judgment of dissolution in her brief filed with this court. The defendant, in his reply brief, argued that the plaintiff waived any right to challenge the timeliness of his appeal because she had failed to file a motion to dismiss within ten days of the filing of the appeal. The *482majority agrees with the defendant’s position in his reply brief and proceeds to review the merits of the defendant’s claim relating to the failure to make factual findings about the child support guidelines. It then reverses the judgment of the trial court despite the defendant’s failure to timely appeal from that judgment.

Because the amount of child support was not challenged until two months after that order had entered, I consider the defendant’s claim to be a collateral attack on the underlying judgment.31 do not believe that we are compelled to review this stale claim simply because the plaintiff did not attack the untimeliness by way of a motion to dismiss. The appeal form did not make it clear that the appeal was being taken from the judgment rendered on February 8, 2011. The defendant simply referred to “the judgment” and did not specify that it was the judgment of dissolution. Parties often refer to decisions on postjudgment motions as being judgments. Furthermore, the preliminary statement of issues filed by the defendant at that time was limited to: “Did the court err in denying defendant’s motions for modification of child support?” When it became clear that the defendant was challenging the underlying judgment at the time he filed his motion for articulation, the plaintiff immediately filed her objection to the untimeliness of that portion of the appeal addressing the underlying dissolution judgment.

I conclude that this court has the discretion to refuse to review stale claims and collateral attacks on judgments regardless of whether the opposing party timely *483challenges those claims by way of a motion to dismiss. We should not be bound by any claimed waiver. In Nicoll v. State, 38 Conn. App. 333, 661 A.2d 101 (1995), this court addressed the reasons for dismissing an untimely appeal. Chief Judge Dupont wrote: “It is well settled that this court has jurisdiction to consider late appeals if, in our discretion, we choose to do so. . . . This is so even when a party timely moves to dismiss an untimely appeal. . . . Given the large number of appeals and motions filed in this court, however, we have adopted a policy that gives precedence to those appeals that are timely filed in compliance with Practice Book § [63-1]. Therefore, when a motion to dismiss that raises untimeliness is, itself, timely filed ... it is ordinarily our practice to dismiss the appeal if it is in fact late, and if no reason readily appears on the record to warrant an exception to our general rule.

“This practice is based in part on the fact that if the untimely appeal is entertained, a delinquent appellant would obtain the benefit of the appellate process after contributing to its delay, to the detriment of others with appeals pending who have complied with the rules and have a right to have their appeals determined expeditiously.'” (Citations omitted; emphasis added.) Id., 335-36.

If we have discretion to consider a late filed appeal, I believe we reasonably also have discretion to refuse to consider a late filed appeal. Under the circumstances of this case, we should decline to address the merits of the defendant’s claim that collaterally attacks the underlying judgment. This action was commenced in 2009, and the record reveals that the case was particularly contentious and reaching agreement on the financial orders was problematic. The case was referred to the family relations office several times during its two year pendency in an attempt to resolve multiple issues. To the credit of the parties, their trial lawyers and the *484family relations office, over time, most of those issues were resolved by agreement. As of the date of trial, only a few outstanding matters remained. I have no doubt that had the plaintiff filed a timely motion to dismiss that portion of the appeal relating to the February 8, 2011 judgment, this court would have granted that motion. For these reasons, I believe that we should exercise our discretion and refuse to address the merits of a stale claim relating to the child support and arrear-age guidelines in the underlying judgment. Accordingly, I would affirm the judgment of the trial court.
