*693 Opinion
This appeal involves a dissolution of marriage action in which the defendant, Bruce L. Bedrick, seeks to enforce a postnuptial agreement. 1 Today we are presented for the first time with the issue of whether a postnuptial agreement is valid and enforceable in Connecticut.
The defendant appeals from the trial court’s judgment in favor of the plaintiff, Deborah Bedrick. The defendant claims that the trial court improperly relied upon principles of fairness and equity in concluding that the post-nuptial agreement was unenforceable and, instead, should have applied only ordinary principles of contract law. We conclude that postnuptial agreements are valid and enforceable and generally must comply with contract principles. We also conclude, however, that the terms of such agreements must be both fair and equitable at the time of execution and not unconscionable at the time of dissolution. Because the terms of the present agreement were unconscionable at the time of dissolution, we affirm the judgment of the trial court.
The record reveals the following undisputed facts and procedural history. In August, 2007, the plaintiff initiated this action, seeking dissolution of the parties’ marriage, permanent alimony, an equitable distribution of the parties’ real and personal property and other relief. The defendant filed a cross complaint, seeking to enforce a postnuptial agreement that the parties exe *694 cuted on December 10, 1977, and modified by way of handwritten addenda on five subsequent occasions, most recently on May 18, 1989.
The agreement provides that in the event of dissolution, neither party will pay alimony. Instead, the plaintiff will receive a cash settlement in an amount to be “reviewed from time to time.” The May 18,1989 addendum to the agreement provides for a cash settlement of $75,000. The agreement further provides that the plaintiff will waive her interests in the defendant’s car wash business, and that the plaintiff will not be held hable for the defendant’s personal and business loans.
In its memorandum of decision, the trial court stated that, although “[t]here is scant case law addressing the enforcement of postnuptial agreements in Connecticut . . . it is clear that a court may not enforce a postnuptial agreement if it is not fair and equitable. . . . [C]ourts have refused to enforce postnuptial agreements for lack of consideration, failure to disclose financial information, or an improper purpose.” Concluding that the agreement was not fair and equitable, the trial court declined to enforce it. The court found that the value of the parties’ combined assets was approximately $927,123, and ordered, inter aha, the defendant to pay lump sum alimony in the amount of $392,372 to the plaintiff. The defendant filed a motion to reargue claiming that the court should have apphed principles of contract law in determining the enforceability of the agreement.
Following reargument, the trial court issued a second written decision, again declining to enforce the post-nuptial agreement, and noting that the Connecticut appellate courts have not yet addressed the issue of the validity of such agreements. The court further declined to apply Connecticut’s law governing prenuptial agreements, reasoning that, unlike a prenuptial *695 agreement, a postnuptial agreement is “inherently coercive” because one spouse typically enters into it in order to preserve the marriage, while the other is primarily motivated by financial concerns.
The trial court additionally determined that, even if postnuptial agreements were valid and enforceable under Connecticut law, the present agreement did not comply with ordinary contract principles because it lacked adequate consideration. The court explained that, because past consideration cannot support the imposition of anew obligation, continuation of the marriage itself cannot constitute sufficient consideration to support a postnuptial agreement. Moreover, the trial court emphasized that the plaintiff did not knowingly waive her marital rights because she neither received a sworn financial affidavit from the defendant nor retained independent legal counsel to review the agreement.
The trial court also opined that enforcement of the agreement would have been unjust and was “not . . . a fair and equitable distribution of the parties’ assets” because the financial circumstances of the parties had changed dramatically since the agreement was last modified in 1989. Since 1989, the parties had had a child together and the defendant’s car wash business had both prospered and deteriorated. This appeal followed. 2
The defendant contends that the trial court improperly applied equitable principles in determining whether the postnuptial agreement was enforceable and, instead, should have applied only principles of contract

Crews
v.
Crews,
The standard applicable to postnuptial agreements presents a question of law, over which our review is plenary. Id., 161. We begin our analysis of postnuptial agreements by considering the public policies served by the recognition of agreements regarding the dissolution of marriage, including prenuptial, postnuptial and separation agreements.
Historically, we have stated that “[t]he state does not favor divorces. ... Its [public] policy is to maintain the family relationship] as a life status.” (Citation omitted.)
McCarthy
v.
Santangelo,
*698
More recently, our court has acknowledged that the government has an interest in encouraging the incorporation of separation agreements into decrees for dissolution. See,
e.g.,Billington v.Billington,
Postnuptial agreements are consistent with public policy; they realistically acknowledge the high incidence of divorce and its effect upon our population. We recognize “the reality of the increasing rate of divorce and remarriage.”
Heuer
v.
Heuer,
Having determined that postnuptial agreements are consistent with public policy, we now must consider what standards govern their enforcement. Neither the legislature nor this court has addressed this question. To aid in our analysis of the enforceability of postnuptial agreements, we review our law on the enforceability of prenuptial agreements. 4 Two different sets of principles govern decisions as to the enforceability of a prenuptial agreement; the date of the execution of the agreement determines which set of principles controls.
Prenuptial agreements entered into on or after October 1,1995, are governed by the Connecticut Premarital Agreement Act, General Statutes § 46b-36a et seq. The statutory scheme provides that a prenuptial agreement is unenforceable when: (1) the challenger did not enter the agreement voluntarily; (2) the agreement was
*700
unconscionable when executed or enforced; (3) the challenger did not receive “a fair and reasonable disclosure of the amount, character and value of property, financial obligations and income of the other party” before execution of the agreement; or (4) the challenger did not have “a reasonable opportunity to consult with independent counsel.” General Statutes § 46b-36g; see also
Friezo
v.
Friezo,
Prenuptial agreements entered into prior to October 1, 1996, however, are governed by the common law, which we analyzed in
McHugh
v.
McHugh,
supra,
“To render unenforceable an otherwise valid [prenuptial] agreement, a court must determine: (1) the parties’ intent and circumstances when they signed the [prenuptial] agreement; (2) the circumstances of the parties at the time of the dissolution of the marriage; (3) whether those circumstances are ‘so far beyond’ the contemplation of the parties at the time of execution; and (4) if the circumstances are beyond the parties’ initial contemplation, whether enforcement would cause an injus
*701
tice.”
Crews
v.
Crews,
supra,
Although we view postnuptial agreements as encouraging the private resolution of family issues, we also recognize that spouses do not contract under the same conditions as either prospective spouses or spouses who have determined to dissolve their marriage. The Supreme Judicial Court of Massachusetts has noted that a postnuptial “agreement stands on a different footing from both a [prenuptial agreement] and a separation agreement. Before marriage, the parties have greater freedom to reject an unsatisfactory [prenuptial] contract. . . .
“A separation agreement, in turn, is negotiated when a marriage has failed and the spouses intend a permanent separation or marital dissolution. . . . The circumstances surrounding [postnuptial] agreements in contrast are pregnant with the opportunity for one party to use the threat of dissolution to bargain themselves into positions of advantage. . . .
“For these reasons, we join many other [s]tates in concluding that [postnuptial] agreements must be carefully scrutinized.” (Citations omitted; internal quotation marks omitted.)
Ansin
v.
Cravin-Ansin,
supra, 457
*702
Mass. 289-90. The Appellate Division of the New Jersey Superior Court has also recognized this “contextual difference” and has noted that a wife “face[s] a more difficult choice than [a] bride who is presented with a demand for a pre-nuptial agreement. The cost to [a wife is] . . . the destruction of a family and the stigma of a failed marriage.”
Pacelli
v.
Pacelli,
Other state courts have not only observed that spouses contract under different conditions; they have also observed that postnuptial agreements “should not be treated as mere ‘business deals.’ ”
Stoner
v.
Stoner,
*703
Prospective spouses share a “confidential relationship”;
Friezo
v.
Friezo,
supra,
Because of the nature of the marital relationship, the spouses to a postnuptial agreement may not be as cautious in contracting with one another as they would be with prospective spouses, and they are certainly less cautious than they would be with an ordinary contracting party. With lessened caution comes greater potential for one spouse to take advantage of the other. This leads us to conclude that postnuptial agreements require stricter scrutiny than prenuptial agreements. In applying special scrutiny, a court may enforce a post-nuptial agreement only if it complies with applicable contract principles, 5 and the terms of the agreement *704 axe both fair and equitable at the time of execution and not unconscionable at the time of dissolution.
We further hold that the terms of a postnuptial agreement are fair and equitable at the time of execution if the agreement is made voluntarily, and without any undue influence, fraud, coercion, duress or similar defect. Moreover, each spouse must be given full, fair and reasonable disclosure of the amount, character and value of property, both jointly and separately held, and all of the financial obligations and income of the other spouse. This mandatory disclosure requirement is a result of the deeply personal marital relationship. 6

Just as “[t]he validity of a [prenuptial] contract depends upon the circumstances of the particular case”;
McHugh
v.
McHugh,
supra,
With regard to the determination of whether a post-nuptial agreement is unconscionable at the time of dissolution, “[i]t 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.” (Internal quotation marks omitted.)
Crews
v.
Crews,
supra,
Unfairness or inequality alone does not render a post-nuptial agreement unconscionable; spouses may agree
*706
on an unequal distribution of assets at dissolution. “[T]he mere fact that hindsight may indicate the provisions of the agreement were improvident does not render the agreement unconscionable.” (Internal quotation marks omitted.)
Lipic
v.
Lipic,
II
Now that we have set forth the applicable legal standards for postnuptial agreements, we turn to the present case and address the question of whether the trial court properly concluded that the parties’ postnuptial agreement should not be enforced.
Although we generally review a trial court’s discretionary decision in a domestic relations case using the clearly erroneous standard of review;
Kiniry
v.
Kiniry,
We therefore provide the following additional facts. Although the value of the parties combined assets is *707 $927,123, the last addendum to the agreement, dated May 18, 1989, provides that the plaintiff will receive a cash settlement of only $75,000. This addendum was written prior to the initial success of the car wash business in the early 1990s, the birth of the parties’ son in 1991, when the parties were forty-one years old, and the subsequent deterioration of the business in the 2000s. At the time of trial, the parties were both fifty-seven years old. Neither had a college degree. The defendant had been steadily employed by the car wash business since 1973. The plaintiff had worked for that business for thirty-five years, providing administrative and bookkeeping support, and since approximately 2001, when the business began to deteriorate, the plaintiff had managed all business operations excluding maintenance. In 2004, the plaintiff also had worked outside of the business in order to provide the family with additional income. Since approximately 2007, when the plaintiff stopped working for the business, the defendant had not been able to complete administrative or bookkeeping tasks, and had not filed taxes.
The trial court found that “[t]he economic circumstances of the parties had changed dramatically since the execution of the agreement” and that “enforcement of the postnuptial agreement would have worked injustice.” It, therefore, concluded that the agreement was unenforceable. Although the trial court did not have guidance on the applicable legal standards for postnup-tial agreements, which we set forth today, we previously have determined that the question of whether enforcement of a prenuptial agreement would be unconscionable is analogous to determining whether enforcement would work an injustice.
Crews
v.
Crews,
supra,
The judgment is affirmed.
In this opinion the other justices concurred.
Notes
A postnuptial agreement is distinguishable from both a prenuptial agreement and a separation agreement. Like a prenuptial agreement, a post-nuptial agreement may determine, inter alia, each spouse’s legal rights and obligations upon dissolution of the marriage. As the name suggests, however, a postnuptial agreement is entered into during marriage — after a couple weds, but before they separate, when the spouses “plan to continue their marriage”; A.L.I., Principles of the Law of Family Dissolution: Analysis and Recommendations (2002) § 7.01 (1) (b), p. 1052; and when “separation or divorce is not imminent.” Black’s Law Dictionary (9th Ed. 2009).
The defendant appealed from the judgment of the trial court to the Appellate Court and we granted his subsequent motion to transfer the case to this court pursuant to General Statutes § 51-199 (c) and Practice Book § 65-2.
The defendant also argues that the trial court improperly considered issues that the plaintiff did not specifically plead. The defendant cites
McKenna v. Delente,
Additionally, the defendant’s argument fails because the prenuptial agreement in
McKenna
was reviewed pursuant to General Statutes § 46b-36g, which delineates the standards for the enforceability of prenuptial agreements. The issue of the enforceability of
postnuptial
agreements is not governed by statute and has not previously been addressed by an appellate court in Connecticut. “Because this case involves ... a question that this court has not previously decided, it is appropriate at the outset to consider generally the enforceability of such agreements.”
McHugh
v.
McHugh,
We do not review our law on the enforceability of separation agreements, which are distinct from both prenuptial and postnuptial agreements and are entered into when spouses have determined to dissolve their marriage. We merely note that their enforcement is governed by General Statutes § 46b-66 (a), which provides in relevant part that “where the parties have submitted to the court an agreement concerning . . . alimony or the disposition of property, the court shall . . . determine whether the agreement of the spouses is fair and equitable under all the circumstances. . . .”
The defendant also argues that the trial court improperly concluded that the postnuptial agreement at issue failed to comply with contract principles because it lacked adequate consideration. Because we conclude that the trial court properly found that the present agreement was unenforceable, we need not address whether the agreement also could have failed for lack of consideration.
General Statutes § 46b-36c, however, expressly provides that prenuptial agreements are enforceable without consideration. Because no similar statute exists for postnuptial agreements, and because such agreements gener *704 ally must comply with contract principles, the present agreement would require adequate consideration to be enforceable.
“Consideration consists of a benefit to the party promising, or . a loss or detriment to the party to whom the promise is made.” (Internal quotation marks omitted.)
Viera
v.
Cohen,
In the present case, the defendant does not argue that a promise to remain married constitutes adequate consideration, and the postnuptial agreement does not refer to any promise to remain married or right to dissolution of marriage. Thus, for purposes of the present dispute, it is irrelevant whether a spouse’s forbearance from bringing a claimed dissolution action and the continuation of the marriage provides adequate consideration for a postnup-tial agreement.
The defendant also argues that the trial court improperly determined that the agreement was unenforceable because the plaintiff did not consult with an attorney. The record, the defendant argues, establishes that the plaintiff had ample time to consult with an attorney, as stated in the text of the agreement itself. Because we conclude that the trial court properly found that the agreement was unenforceable, we do not address this argument beyond noting that, in evaluating the circumstances surrounding a *705 particular agreement, the court should examine the parties’ knowledge of their rights and obligations and whether they had a reasonable opportunity to confer with independent counsel.
