Central questionWhat is the Miglin test for spousal support agreements?

Key takeaways {#takeaways}

  • A spousal support waiver is not automatically final: courts apply Miglin's two-stage test before enforcing it.
  • Stage one reviews how the agreement was negotiated and whether its substance met the Divorce Act's objectives.
  • Stage two asks whether current circumstances fall significantly outside what the parties reasonably anticipated.

Miglin v Miglin at a glance {#summary}

The Miglin test is the Supreme Court of Canada's two-stage framework for deciding whether a spousal support agreement should hold when one spouse later applies for support under the Divorce Act. Stage one examines the negotiation and the agreement's substance at signing; stage two asks whether things have since moved significantly outside what the parties anticipated.

Most people assume a signed, final separation agreement ends the support question for good. Linda Miglin signed exactly that kind of agreement — a full spousal support release, negotiated over 15 months with lawyers on both sides — then applied for support anyway. Two Ontario courts gave it to her. The Supreme Court of Canada reversed, and in doing so wrote the rulebook for when a support waiver survives.

The facts {#facts}

Linda and Eric Miglin separated in 1993 after 14 years of marriage. They had four children, aged 2 to 7 and a half at separation (para 6). Together they owned Killarney Lodge, a resort in northern Ontario, as equal shareholders. He ran the financial side; she ran day-to-day operations. At separation, each drew a salary of $80,500 from the business (para 9).

After 15 months of negotiation, with both spouses represented by experienced counsel, they signed a Separation Agreement dated June 1, 1994 (para 11). Its key terms (paras 13, 16-17):

  • A full and final release of spousal support by both spouses, stating each accepted the deal even if "radical, material, profound or catastrophic changes" occurred (para 13).
  • Ms. Miglin transferred her half of the Lodge to Mr. Miglin; he transferred his half of the matrimonial home to her. Each asset had a net value of roughly $500,000, and he took over the mortgage (para 16).
  • Child support of $1,250 per child per month — about $60,000 a year — indexed to the cost of living (para 16).
  • A Consulting Agreement paying Ms. Miglin $15,000 a year for defined work for the Lodge, for a five-year term renewable only if both agreed (para 17).

The divorce went through in January 1997. Relations later broke down, and in June 1998 — before the consulting contract expired — Ms. Miglin applied for sole custody, child support and spousal support (para 19).

The trial judge treated the consulting contract as "thinly veiled" spousal support, found the deal unfair, and awarded her $4,400 a month in spousal support for five years (para 21). The Ontario Court of Appeal upheld the award and removed the five-year limit, applying a "material change" threshold (paras 22-23).

The legal issues {#issues}

  1. When one spouse applies for spousal support under s. 15.2 of the Divorce Act despite a final agreement waiving support, what weight does the agreement get? (paras 1-3)
  2. Did the older Pelech trilogy — which let courts override a final agreement only for a radical, unforeseen change causally connected to the marriage — still govern under the 1985 Divorce Act? (para 28)
  3. Did the trial judge's comments and interventions create a reasonable apprehension of bias? (para 25)

What the court decided {#decision}

By a 7-2 majority (reasons by Bastarache and Arbour JJ., with LeBel J. writing the dissent for himself and Deschamps J.), the Court allowed Mr. Miglin's appeal and restored the agreement's spousal support release (para 107).

The majority held:

  • The Pelech trilogy's narrow test — radical, unforeseen change causally connected to the marriage — no longer fits the 1985 Divorce Act. Its single-minded focus on a "clean break" and self-sufficiency is inconsistent with the compensatory and non-compensatory models of support the Court developed in Moge and Bracklow (paras 40, 47).
  • But there is no "change" threshold at all in s. 15.2, so the Court of Appeal was wrong to import a "material change" test, and the trial judge was wrong to apply a loose "fairness" test that simply substituted his view for the parties' bargain (paras 43, 58, 61).
  • Instead, courts apply a two-stage analysis looking at the agreement first at formation and then at the time of the application (para 64) — the framework set out below.
  • Applied here, the agreement deserved "significant and determinative weight": the negotiation was long, professionally supported and free of exploited vulnerability (paras 92-93); the substance complied substantially with the Act's objectives (paras 94-99); and nothing at the time of the application fell outside what the parties had reasonably anticipated — Ms. Miglin's own advisers had planned for the consulting income ending, and her net worth had in fact increased by at least 20 per cent, to $750,000 with essentially no debt (paras 103-105).
  • The bias challenge failed: the trial judge's comments were "intemperate" but did not meet the high threshold for reasonable apprehension of bias (para 26).

Where the law stands now. Miglin remains the governing framework when a spouse applies for support under s. 15.2 of the Divorce Act in the face of an agreement; the Supreme Court considered and applied its principles as recently as Anderson v Anderson, 2023 SCC 13, while cautioning that Miglin "is not, and was never intended to be, a framework of general applicability" for every kind of domestic contract and should not be transposed into provincial property legislation. In BC, agreements about spousal support also engage the Family Law Act: s. 164 sets out its own statutory grounds for setting aside a written spousal support agreement — non-disclosure, taking improper advantage of vulnerability, lack of understanding, common law contract defects, or "significant unfairness" assessed against factors that echo Miglin (time passed, changed circumstances, the intention to achieve certainty, reliance, and the support objectives in s. 161). Which track applies depends on which statute the claim is brought under; many BC claims can engage both.

What is the Miglin test for spousal support agreements? {#the-test}

The Miglin test asks two questions, in order, when someone applies for spousal support despite a prior agreement (paras 64, 80-91).

Stage one — the agreement when it was made. The court first looks at the circumstances of negotiation and execution: was there oppression, pressure or other vulnerability, and did the other spouse take advantage of it? Vulnerability is not presumed, and independent professional advice will often offset any imbalance (paras 81-83). If the negotiation stands up, the court then reviews the substance: did the agreement, taken as a whole, comply substantially with the objectives of the Divorce Act — not just the support objectives in s. 15.2(6), but also certainty, finality and autonomy? Only a significant departure from those overall objectives justifies intervention (paras 84-85).

Stage two — the situation at the time of the application. Even a properly made agreement can lose its force. The court asks whether the applicant's current circumstances represent a significant departure from the range of reasonable outcomes the parties anticipated, in a way that puts the agreement at odds with the Act's objectives (paras 87-88, 91). The change does not have to be radical, unforeseen, or causally connected to the marriage — that was the old Pelech standard — but ordinary ups and downs (job market shifts, harder-than-expected parenting, asset values moving) will not be enough, because some change is foreseeable in almost every life (para 89).

If the agreement passes both stages, the court defers to it. If it fails, the court still must consider it under s. 15.2(4)(c) — failure does not mean the whole agreement is ignored (paras 86, 90).

The framework {#numbers}

Stage Question What the court looks at Source
1(a) — Circumstances of execution Was the bargaining process fundamentally flawed? Oppression, pressure, exploited vulnerability; duration of negotiations; professional (legal, financial) assistance paras 81-83
1(b) — Substance at formation Did the agreement substantially comply with the Divorce Act? The whole deal, not just support clauses; s. 15.2(6) objectives plus certainty, finality, autonomy; only a significant departure warrants intervention paras 84-86
2 — Time of application Do current circumstances make reliance on the agreement unacceptable? Whether the situation is a significant departure from the range of reasonable outcomes anticipated; no need for radical change or causal connection to the marriage; foreseeable change is not enough paras 87-91

What this means if you're separating in Surrey {#bc-impact}

If you are negotiating a separation agreement in BC, Miglin cuts both ways. It gives well-made agreements real staying power: if you both had independent legal advice, exchanged full financial information, and took the time to negotiate properly, a court will be reluctant to reopen your deal. The Miglins' agreement survived precisely because the process was careful — 15 months of negotiation, experienced lawyers on both sides, and detailed financial advice throughout.

It also means a support waiver is not a magic phrase. A release signed under pressure, without advice, or on incomplete disclosure is vulnerable at stage one. And even a clean agreement can be revisited if life later moves far outside what you both planned for — though ordinary setbacks will not qualify.

For married spouses, a support claim despite an agreement can proceed under the Divorce Act, where Miglin applies directly. Unmarried spouses who qualify under BC's Family Law Act, and married spouses claiming under that Act, face the statutory set-aside grounds in FLA s. 164 instead. The practical lesson is the same on either track: process protects the deal. That is one reason negotiated or mediated agreements, done properly, tend to hold — and why cutting corners to sign quickly can undo everything later. See our divorce in BC overview for how support fits into the bigger picture.

How a lawyer uses Miglin {#in-practice}

When drafting, a family lawyer builds a Miglin-proof record: independent legal advice for both spouses, documented financial disclosure, unhurried negotiation, and recitals showing the agreement was meant to be final and why the trade-offs made sense to these particular spouses. The Court stressed that parties may weigh things differently than a judge would, and that is their right (paras 55, 66).

When attacking or defending a waiver, counsel works through the stages in order. Stage one arguments focus on the negotiation record: who had advice, what was disclosed, how long it took, whether one spouse exploited the other's vulnerability. Stage two arguments focus on the gap between the life the agreement assumed and the life that actually happened — and whether that gap was of a kind the parties should be taken to have accepted. Miglin itself shows how stage two fails: the wife's advisers had projected the end of her consulting income, so its expiry could not later count as an unanticipated departure (para 103).

A BC lawyer also decides which statutory track serves the client — Divorce Act s. 15.2 with Miglin, or FLA s. 164 — and pleads accordingly. For worked examples of agreement disputes, see our case studies.

Frequently asked questions {#faq}

Can I waive spousal support forever in a separation agreement?

You can sign a full and final release, and Miglin shows courts will enforce one that was properly negotiated and substantially fair when made. But no waiver is beyond review. A court can still intervene if the process was flawed or if your circumstances later fall significantly outside what you both reasonably anticipated. In BC, the Family Law Act adds its own statutory set-aside grounds in s. 164.

Does the Miglin test require a big change in circumstances?

No threshold "change" is required — that was the point of rejecting both the old Pelech "radical change" rule and the Court of Appeal's "material change" test. At stage two, what matters is whether current circumstances are a significant departure from the range of outcomes the parties reasonably anticipated. Foreseeable ups and downs — job changes, parenting getting harder, asset values shifting — will generally not be enough (para 89).

Does Miglin apply to my BC agreement?

If you claim spousal support under the Divorce Act despite an agreement, yes — Miglin supplies the framework, and the Supreme Court applied its principles again in Anderson v Anderson in 2023. If your claim is under BC's Family Law Act, the court applies the statutory tests in s. 164 instead, which cover similar ground in a different structure. Many separating spouses in BC could proceed under either statute, so getting advice on which applies to you matters.
