“So while the proper interpretive framework for assessing a domestic contract is statute-specific, useful principles emerge from Miglin and this Court’s subsequent jurisprudence that aid in this judicial assessment. As a starting point, domestic contracts should generally be encouraged and supported by courts, within the bounds permitted by the legislature, absent a compelling reason to discount the agreement (Miglin, at para. 46; D.B.S., at para. 76; Rick, at para. 45). This deference flows from the recognition that self-sufficiency, autonomy and finality are important objectives in the family law context (Miglin, at para. 28). Not only are parties better placed than courts to understand what is fair within the context of their relationship, but the private resolution of family affairs outside the adversarial process avoids the cost and tumult of protracted litigation (paras. 45-46; see also Association de médiation familiale du Québec v. Bouvier, 2021 SCC 54, at paras. 44 and 134).
At the same time, negotiations over domestic contracts take place in a singularly challenging environment, often at a time of acute emotional stress, “in which one or both of the parties may be particularly vulnerable” (Miglin, at para. 74; see also Rick, at para. 47; C. Rogerson, “Miglin v. Miglin, 2003 SCC 24: ‘They are Agreements Nonetheless’” (2003), 20 Can. J. Fam. L. 197, at p. 225). In this context, the simple application of ordinary principles of contractual validity may be inadequate to quiet concerns of imbalance and exploitation (Miglin, at para. 77; M. Shaffer, “Domestic Contracts, Part II: The Supreme Court’s Decision in Hartshorne v. Hartshorne” (2004), 20 Can. J. Fam. L. 261, at p. 286). Rather, judges must approach family law settlements with a view to balancing the values of contractual autonomy and certainty with concerns of fairness. In essence, judges are to review domestic contracts with particular sensitivity to the vulnerabilities that can arise in the family law context, without presuming that spouses lack the agency to contract simply because the agreement was negotiated in an emotionally stressful context (Miglin, at para. 82; see also R. Leckey, “Contracting Claims and Family Law Feuds” (2007), 57 U.T.L.J. 1, at p. 14; Bailey, at p. 102 (citing the gendered unfairness that may arise from presuming incapacity to contract where a bargain is struck in an emotional context)).
Concern about vulnerabilities may be countered by the presence of procedural safeguards. For example, full and frank disclosure of all relevant financial information between the parties can go far to assuage concerns of informational asymmetry (Rick, at para. 47; Colucci v. Colucci, 2021 SCC 24, at para. 51). Similarly, professional assistance, such as independent legal advice, can serve as a hallmark of a fair bargaining process (Miglin, at para. 82; Rick, at paras. 60-61), although the curative impact of legal advice in the negotiation of domestic contracts should not be taken as given. As La Forest J. recognized, dissenting in Richardson v. Richardson, 1987 CanLII 58 (SCC), [1987] 1 S.C.R. 857, divorce is one of the most stressful periods in an individual’s life and many people do “very unwise things, things that are anything but mature and sensible, even when they consult legal counsel” (p. 883). Courts must have careful regard to the financial and emotional pressures that characterized the relationship, and not simply presume that legal advice immunizes a contract from unfairness.
The rigour of a court’s review of a domestic contract depends on the authorizing statute. Some statutes provide that a domestic contract may only be set aside where it is unconscionable, for example (see Family Law Act, R.S.O. 1990, c. F.3, s. 33(4)), while others use the measures of “inequitable” or “undue influence” (see Marital Property Act, R.S.N.B. 2012, c. 107, s. 43; Family Property and Support Act, R.S.Y. 2002, c. 83, s. 2(4)). In any case, however, fairness review of a domestic contract typically looks both to the circumstances surrounding the contract’s execution and to the substance of the agreement, where such a review is authorized by governing legislation. As Abella J. stated in Rick, at para. 50: “. . . the best way to protect the finality of any negotiated agreement in family law is to ensure both its procedural and substantive integrity in accordance with the relevant legislative scheme”.
An assessment of the substance of the agreement is generally determined by reference to the governing legislative regime. The purposes and criteria of the statute provide an objective yardstick against which to assess the parties’ subjective understanding of what is fair, and limit the risk that parties will depart significantly from public policy goals expressed by the legislature. Measuring the substance of the agreement against the legislation also helps to promote greater certainty for parties, who may rely on their statutory entitlements as a reference point in organizing their personal affairs (M. Shaffer and C. Rogerson, “Contracting Spousal Support: Thinking Through Miglin” (2003), 21 C.F.L.Q. 49, at p. 61).
In sum, our jurisprudence on domestic contracts, beginning with Miglin, values the principles of autonomy and certainty by encouraging parties to arrange their intimate affairs outside the court system. But the emotional complexities of family dynamics make contracting over domestic affairs unlike regular arm’s length transactions. The unique context out of which these agreements arise requires courts to approach them with keen awareness of their potential frailties to ensure fairness, having regard for the integrity of the bargaining process and the substance of the agreement.”
