Opinion
In this сertified appeal, the plaintiff, Melinda Crews, appeals from the judgment of the Appellate Court reversing in part the judgment of the trial court with regard to certain financial orders included in the dissolution of her marriage to the defendant, Stephen Crews.
Crews
v.
Crews,
The Appellate Court majority opinion summarized the following relevant facts as found by the trial court: “The parties met at a corporate outing when they both were employed by the General Electric Corporation (General Electric). At the time, the defendant was the divorced father of three children. The plaintiff had not been married previously. The defendant holds a bachelor’s degree; the plaintiff has bachelor’s and master’s *156 degrees. The defendant was then residing in the future marital home, a house that he had purchased from his mother in an arm’s-length transaction on December 31, 1986. The plaintiff owned a condominium unit in Bridgeport. At the time, each of the parties had bank accounts, pension plans and investments.
“The parties became engaged in January, 1988, and were married on June 25, 1988. About one year prior to their wedding, the defendant raised the subject of an antenuptial agreement. The defendant believed he had been ‘burned’ in his previous divorce and declared: ‘No agreement; no wedding!’ The plaintiff told the defendant that she was ‘no fan [of an antenuptial agreement], but agreed with him in concept.’ The defendant described the agreement as a precondition to the wedding itself and presented the plaintiff with a draft of the agreement on May 31, 1988. The parties signed the agreement on June 24, 1988, one day before they were married.
“Following their marriage, the parties resided in the marital home and had two children, a daughter bom in May, 1989, and a learning disabled son bom in May, 1992. Both parties were employed during their marriage, and initially each of them traveled extensively in connection with his or her employment. At the time of [the dissolution] trial, the defendаnt had been employed by General Electric for thirty-nine years, where he earned an annual base salary of $131,000 and regularly received annual bonuses. His annual net income was $98,540 at the time of dissolution. The [trial] court made no finding that the nature of the defendant’s employment changed during the marriage from what it had been prior to the marriage. During the marriage, he also acquired General Electric stock and stock options, some of which was encumbered by margin loans. He also participated in two executive compensation plans in the 1990s.
*157 “The plaintiff was fifty-three [years old] at the time of dissolution [in 2005]. From 1981 through 1986, she was a technical writer for General Electric, earning $50,000 per year. She left General Electric to join Practice Media and later the NYNEX Corporation. She worked steadily during the marriage, except for a three month maternity leave she took following the birth of each child. After the birth of the parties’ children and an automobile accident, the plaintiff decided that corporate travel was too much for her in addition to her responsibilities at home. In 1993, she formed her own business known as M. Crews & Company, LLC, which she operated out of the marital home until just prior to trial. The value of the plaintiffs business then was about $96,000, and she had an annual net income of $69,056.” Id., 282-84.
The plaintiff filed her dissolution action in May, 2004. In her complaint, the plaintiff requested alimony, assignment of the maritаl home, an equitable division of marital assets and attorney’s fees. In response, the defendant filed a cross complaint in which he sought enforcement of the antenuptial agreement, which he claimed established the appropriate financial determinations upon dissolution. The antenuptial agreement precluded the trial court from awarding the plaintiff alimony, a share in the marital home, a portion of the defendant’s retirement and investment assets and attorney’s fees.
Following a trial in June, 2005, the trial court rendered a judgment of dissolution, but refused to enforce the terms of the antenuptial agreement. The trial court determined that the antenuptial agreement was not governed by the provisions of the Connecticut Premarital Agreement Act (act),
1
General Statutes § 46b-36a et seq.,
*158
presumably because the act applies only to antenuptial agreements entered into on or after October 1, 1995; General Statutes § 46b-36a; and the parties had entered into their agreement on June 24, 1988. The trial court concluded, instead, that the antenuptial agreement was governed by the equitable rules established in
McHugh
v. McHugh,
The trial court concluded that enforcing the antenuptial agreement would be unjust under McHugh. It determined that a dramatic change in the parties’ economic circumstances had occurred between the time that the agreement was executed and the time of the dissolution proceedings, which rendered enforcement of the ante-nuptial agreement inequitable. The trial court therefore ordered the defendant to make the following payments to the plaintiff: monthly alimony of $1000 until the death of either party, the plaintiffs remarriage, or August 31, 2010, whichever occurs first; $450,000 to compensate the plaintiff for her contribution to the appreciation in value of the marital home and for her share of the defendant’s pension and investment accounts; and $25,000 for her attorney’s fees.
The defendant appealed from the judgment of the trial court to the Appellate Court, claiming that the trial court, inter alia, improperly had failed to enforce the antenuptial agreement.
Crews
v.
Crews,
supra,
We begin our analysis with a brief overview of our common law governing antenuptial agreements. In
McHugh
v.
McHugh,
supra,
On appeal, in both the Appellate Court and this court, the parties have not challenged the trial court’s conclusion pursuant to
McHugh
that the parties validly entered into the agreement and that the terms of the agreement do not violate state or public policy. See
Crews
v.
Crews,
supra,
I
The plaintiff first claims that the Appellate Court incorrectly аpplied plenary review to the trial court’s *161 decision that the antenuptial agreement between the parties was unenforceable. Specifically, the plaintiff contends that the Appellate Court should have reviewed the judgment of the trial court for abuse of discretion because the trial court based its decision on factual and equitable determinations that normally receive abuse of discretion review. The defendant responds that the Appellate Court properly applied plenary review because the trial court’s decision was a legal determination governed by principles of contract law, and therefore is appropriately subjected to plenary review. We agree with the defendant.
The Appellate Court majority determined that plenary review was appropriate in this case due to the nature of the McHugh analysis. As the majority summarized: “[w]hen an appellant’s claim alleges that the facts found by the court were insufficient to support its legal conclusions, we are presented with a mixed question of fact and law to which the plenary standard of review applies. . . . Our task is to determine whether the court’s conclusions are legally and logically correct and find support in the facts that appear in the record.” (Citations omitted.) Id., 289.
We begin our analysis with our own standard of review. Determining the appropriate standard of review is a question of law, and as a result, it is subject to plenary review. See, e.g.,
Fish
v.
Fish,
As previously set forth herein, this appeal turns on the third
McHugh
prong, namely, whether the circum
*162
stances at the time of dissolution were so “beyond the contemplation” of the parties at the time the antenuptial agreement was signed that enforcement of the agreement would work an injustice.
McHugh
v.
McHugh,
supra,
Moreover, “[s]o-cailed mixed questions of fact and law, which require the application of a legal standard to the historical-fact determinations, are not facts in this sense. . . . [Such questions require] plenary review by this court unfettered by the clearly erroneous standard. . . . When legal conclusions of the trial court are challenged on appeal, we must decide whether [those] . . .
*163
conclusions are legаlly and logically correct and find support in the facts that appear in the record.” (Citation omitted; internal quotation marks omitted.)
Friezo
v.
Friezo,
Whether enforcement of an agreement would work an injustice is analogous to determining whether enforcement of an agreement would be unconscionable. It is well established that “[t]he question of unconscionability is a matter of law to be decided by the court based on all the facts and circumstances of the case. . . . Thus, our review on appeal is unlimited by the clearly erroneous [or abuse of discretion] standard. . . . This means that the ultimate determination of whether a transaction is unconscionable is a question
*164
of law, not a question of fact, and that the trial court’s determination on that issue is subject to a plenary review on appeal.” (Citations omitted; internal quotation marks omitted.)
Cheshire Mortgage Service, Inc.
v.
Montes,
The plaintiff nevertheless contends that the abuse of discretion standard is normally employed to review family law matters. Although this is true, the abuse of discretion standard applies only to decisions based solely on factual determinations made by the trial court. See, e.g.,
Simms
v.
Simms,
II
The plaintiff next claims that even if the Appellate Court properly employed a plenary standard of review, it improperly applied that standard to the facts of the present case. Specifically, the plaintiff contends that the trial court’s conclusion that enforcement of the antenuptial agreement would result in an injustice is supported by the evidence in the record. The defendant responds that the Appellate Court correctly applied the plenary standard of review, and, further, that there is insufficient evidence in the record to demonstrate that the change in the circumstances between the parties at the time of dissolution was not contemplated. We agree with the defendant.
The following additional facts and procedural history are relevant to our analysis. The antenuptial agreement between the parties established their financial rights and responsibilities during the marriage, upon dissolution of the marriage, and uрon the death of either party. During the marriage, each party was required to maintain continuous, gainful employment and to take all necessary measures to prevent voluntary or involuntary termination of his or her employment. The parties further agreed during the marriage to keep their respective property separate, whether owned prior to the marriage or acquired during the marriage. Each party also relinquished all rights, including all statutory rights and interests, in the other’s probate estate.
The antenuptial agreement additionally provided that, in the event of dissolution, neither party would seek or accept any cash, property, alimony, attorney’s fees or any other property from the other. In the event of divorce, the parties would be allowed to keep their *166 separately owned property acquired either before or during the marriage, as well as their share of the marital property. The marital property would be divided in proportion to their respective contribution toward the purchase of that property. Other provisions related to child support and custody, including a provision that in the event of dissolution, child support would be determined on the basis of “the needs and best interest of the child and not as a function of the wealth of the noncustodial parent.”
In its memorandum of decision, the trial court determined that the pаrties’ financial circumstances had “changed dramatically” between the time they signed the agreement and the time of the dissolution, thus rendering the agreement unenforceable pursuant to the third prong of McHugh. The court reasoned that “the agreement was valid and enforceable at the time of its execution . . . [but] that the evidence supports a finding that the economic circumstances of the parties have changed dramatically between the date of the agreement and the dissolution, in particular the economic circumstances of the [defendant], due insubstantial part to the efforts of the [plaintiff], that given the length of the marriage, the birth of two children, and the substantial financiаl and nonfinancial contributions of the [plaintiff] from employment outside of the home to her parenting and homemaking efforts, it would be inequitable to enforce the terms of the prenuptial agreement of the parties.”
The Appellate Court majority disagreed, concluding that “the [trial] court’s finding that the changed circumstances were beyond the contemplation of the parties at the time they signed the agreement ... is not supported by the record.”
Crews
v.
Crews,
supra,
We begin with our standard of review. As we concluded in part I of this opinion, the trial court’s analysis under
McHugh
involved a mixed question of fact and law. These issues require “plenary review by this court unfettered by the clearly erroneous standard. . . . When legal conclusions of the trial court are challenged on appeal, we must decide whether [those] . . . conclusions are legally and logically correct and find support in the facts that appear in the record.” (Citation omitted; internal quotation marks omitted.)
Friezo
v.
Friezo,
supra,
We now turn to the text of the third prong of
McHugh,
which provides that “[ajntenuptial agreements relating to the property of the parties, and more specifically, to the rights of the parties to that property upon the dissolution of the marriage, are generally enforceable
*168
... [if] the circumstances of the parties at the time the marriage is dissolved
are not so beyond the contemplation
of the parties at the time the contract was entered into as to cause its enforcement to work injustice.” (Emphasis added.)
McHugh
v.
McHugh,
supra,
The Appellate Court majority correctly determined that the trial court failed to make the requisite findings required by
McHugh
in concluding not to enforce the terms of the antenuptial agreement. As the Appellate Court noted, “[i]t is apparent that the [trial] court, in rendering its judgment, was moved by equitable considerations codified in our statutes. . . . The agreement required the court to adjudicate a contract action in which the traditional notions of equity are not germane because there was an agreement . . . and the evidence does not support a finding that there was a dramatic change in the parties’ financial circumstances. ... In other words, whether the trial court or this court thinks the agreement was a good bargain for the plaintiff does not enter into the analysis . . . .” (Citations omitted.)
Crews
v.
Crews,
supra,
It is additionally clear that the party seeking to challenge the enforceability of the antenuptial contract bears a heavy burden. In explaining the third prong in
McHugh,
this court offered the example that “where the economic status of [the] parties has
changed dramatically
between the date of the agreement and the dissolution, literal enforcement of the agreement may work injustice. Absent such
unusual circumstances,
however, antenuptial agreements freely and fairly entered into
will be honored and enforced by the courts as
written.” (Emphasis added.)
McHugh
v.
McHugh,
supra,
*170
Although this court previously has not construed the third prong of
McHugh
in any significant manner, precedent from the Appellate Court supports our conclusion that proving uncontemplated, dramatically changed circumstances requires a significant showing. In
Winchester v. McCue,
supra,
In the present case, it is clear that the Appellate Court majority properly recognized and applied the plaintiffs heightened burden. The court concluded that “[p]ursuant to
McHugh
and
Winchester,
which make it clear that the threshold for a finding of dramatic change in circumstances is high . . . not only does the evidence not support the [trial] court’s conclusion that there was a dramatic change in the financial circumstances of the parties between the time of their marriage and its dissolution but also [that court’s determination] that the financial circumstances that existed at the time of dissolution were well within the contemplation of the parties when they signed the agreement, i.e., that is why the defendant wanted the plaintiff to sign the agreement.”
Crews s. Crews,
supra,
*171
Moreover, the evidence supports the Appellate Court’s conclusion that the circumstances at the time of dissolution were consistent with the parties’ expectations and the intended purpose of the antenuptial agreement. Id. For instance, the antenuptial agreement had an express provision affirming the obligation of both parties to remain gainfully employed. In accordance with this obligation, the defendant maintained his employment during the length of the marriage. He therefore continued to receive his salary, bonuses and retirement and investment benefits, all of which continued to increase as he remained employed at General Electric and advanced his career. As the Appellate Court properly noted, “[t]hе plaintiff has not argued that the appreciation of the defendant’s assets was not in keeping with the economy’s growth during the marriage.” Id., 294. The court specifically noted that, “[t]he plaintiff has not brought to our attention any evidence that the nature of the defendant’s employment changed or that his salary and benefits changed in any fashion other than what one might expect for someone in his position.” Id., 295; see also
Winchester
v.
McCue,
supra,
Moreover, the Appellate Court correctly noted that “[b]y signing the [antenuptial] agreement, the plaintiff also recognized that the defendant desired to segregate all of his property from any interest she may have had in it”;
Crews
v. Crews, supra,
The evidence also clearly supports the Appellate Court’s refusal to credit the trial court’s emphasis on the plaintiffs employment and homemaking efforts. As the Appellate Court summarized: “We also cannot agree [with the trial court’s conclusion] that the plaintiffs efforts alone contributed to the increased value of the parties’ finances. . . . Pursuant to the [antenuptial] agreement, the plaintiff agreed to work throughout the marriage.” (Emphasis added.) Id., 296. The antenuptial agreement plainly requires both parties to maintain employment. It further contemplated the birth of children as evidenced by select provisions addressing the amount of maternity leave that the plaintiff would be allowed. Yet, despite its contemplation of the birth of children, the antenuptial agreement clearly intended and required that the plaintiff maintain her employment. It would be inappropriate, therefore, to give the plaintiff additional consideration for fulfilling her contractual obligation.
We conclude that the Appellate Court properly ordered the trial court to enforce the provisions for which the plaintiff contracted. The circumstances of the parties at the time of dissolution accurately reflected their initial intention as expressed in the agreement, namely, two working adults with separate
*173
financial arrangements and assets, each protected from claims by the other. As the antenuptial agreement provides, both the plaintiff and the defendant “[desire] to keep all of [his or her] property, now owned or hereafter acquired, free from any claim that [the other] might otherwise acquire by reason of the marriage, [or] any dissolution thereof . . . .’’In the absence of a clear indication that the antenuptial agreement is unenforceable because it was not validly entered into, that it violated public policy, or that it would be unjust to enforce the agreement due to a significant and uncontemplated change in the parties’ circumstances;
McHugh
v.
McHugh,
supra,
The judgment of the Appellate Court is affirmed.
In this opinion the other justices concurred.
Notes
The act provides, inter alia, that a premarital agreement is not enforceable against a party if that party proves one or more of several conditions: the agreement was not entered into voluntarily; the agreement is unconscionable; the parties did not fairly and reasonably disclose financial assets or obligations prior to signing the agreement; or the complaining party did not
*158
have a reasonable opportunity to consult with independent counsel. General Statutes § 46b-36g (a); see
Friezo
v.
Friezo,
We granted the plaintiffs petition for certification to appeal from the Appellate Court limited to the following issues: (1) “Did the Appellate Court properly apply a plenary standard of review to the trial court's conclusion that enforcement of the parties’ antenuptial agreement as of the date of dissolution would work an injustice?” (2) “Even if the Appellate Court рroperly applied a plenary standard of review, did the Appellate Court properly reverse the trial court’s judgment that enforcement of the parties’ antenuptial agreement as of the date of dissolution would work an injustice?”
Crews
v.
Crews,
Several other states also view antenuptial agreements as contracts governed by the same principles applied to contracts generally. See, e.g.,
Peden
v.
Peden,
Neither party claims that the antenuptial agreement is unclear or ambiguous.
The common law of other states is consistent with our conclusion that the party who challenges an antenuptial agreement faces a significant burden. See, e.g.,
MacFarlane
v.
Rich,
