Mutual
Clause

In 1972 Canada recorded 200,470 marriages, a crude rate of 9.0 per thousand people. By 2020 the country recorded 98,355, a rate of 2.6 per thousand. Roughly the same population, a third of the weddings.

Divorces fell too. They peaked at 97,773 in 1987, the year after the Divorce Act was reformed, and by 2020 had dropped to 42,933 — from 12.7 per thousand married persons in 1991 down to 5.6.

It is tempting to read the second number as a recovery. Couples are staying together. Something is working.

The third number spoils it. In 1981, 6% of Canadian couples were living common-law. By 2021 it was 23%.

A divorce statistic can only count people who were married. As a quarter of couples moved into a category that produces no divorce filing, the divorce rate fell without anything about human behaviour improving. The separations still happen. They simply happen somewhere the statistics do not look.

The fertility figure is not a side note. At 1.25 children per woman, Canada sits below the 1.30 line demographers call ultra-low, and the average age of mothers at birth has moved from 26.7 in 1976 to 31.8 in 2024. Households are forming later, smaller, and more often without the legal event that used to define them.

Here is the part most people in Saskatchewan do not know.

Under The Family Property Act, once two people have lived together for two years — or immediately, if there is a child — the province treats them on substantially the same terms as a married couple. Family property is divided equally. That covers the family home, household goods, pensions, RRSPs and investments, regardless of whose name is on the title.

No ceremony. No licence. No signature. No letter in the mail telling you the date it happened.

Now cross a provincial border with exactly the same relationship.

Two couples, identical in every respect except geography, arrive at opposite financial outcomes. One splits everything. One splits nothing and argues about it in court. British Columbia looks like Saskatchewan; Alberta and Manitoba are different again.

Nobody chooses this. You accrue into it. The default is written by the legislature of whichever province you happened to sign a lease in, and the clock starts on a date neither person marks.

That is not an argument against the law. Equal division exists for a good reason, and the reason is the next section. It is an argument about consent: a rule that reallocates half of what two people own should probably be a rule they know about.

Equal division of family property is a fairness mechanism, and it was built for a specific arrangement: one person earns wages, the other does unpaid work at home, and at the end only one of them has a name on the deed, the pension and the bank account.

Split it in half and the arrangement becomes fair. Without that rule, decades of unpaid domestic work would convert to nothing. The rule is not an accident and it is not obsolete.

But it was designed around a household with a clear division of labour, a single earner, and a marriage certificate. Today the earning is usually shared, the certificate is increasingly absent, and the domestic labour is split — unevenly, but split.

The mechanism is still applied at full strength to arrangements it was never modelled on: two earners with separate careers, unequal assets brought in, a house one of them bought before they met, a business one of them started, and no wedding to mark the moment any of it became joint.

Between late December 2025 and January 2026, BMO surveyed 2,503 Canadian adults about money and partnership. The results read less like a personal finance study and more like a description of how couples now form.

Two of those numbers deserve to be read together.

Thirty-seven percent of divorced or separated Canadians say the cost of divorce kept them married longer than they wanted to be. Not doubt, not children, not hope. Cost. The exit was priced out of reach, so they stayed.

Thirty-three percent say they felt pressured to move in together to save money.

Put those side by side with section two. A third of people are being pushed by rent into cohabitation, and in Saskatchewan cohabitation is a two-year fuse on an equal-division claim over everything either of them owns. The economic pressure and the legal consequence are pointing at the same people, and almost none of them have been told.

The unpaid work gap has narrowed and it has not closed. In 2011, meal preparation was done mostly by the woman in 62.0% of Canadian couples; by 2020 that was 47.5%. Laundry moved from 66.6% to 55.9%. Real movement, one generation.

The daily minutes still tilt.

Forty minutes a day of housework. Fifty-two minutes a day of childcare. Over a decade that is not a rounding error, and it is precisely the contribution that equal division was invented to protect.

But the most revealing number in this whole file is not a minute count. Asked whether they were satisfied with how housework was divided in their home, 88.4% of men said yes. Among women it was 76.3% — and 9.7% of women were actively dissatisfied against 2.6% of men.

The same household. Two different readings of whether it is fair. That gap is not a dispute about facts; both people can see the dishes. It is a dispute about what counts, and it goes unspoken because nothing in an ordinary relationship ever requires it to be said out loud.

Which may be why the instrument once treated as an insult is being picked up by the people it was supposedly aimed at. In the United States, where the data is better, prenuptial agreements went from 3% of adults in 2010 to 15% by 2022, and near 40% among those aged 18 to 34. More than half of prenup processes are now initiated by women — not out of distrust, but out of a preference for financial autonomy over financial dependence.

The clause at the edge: privacy

The furthest frontier of all this is the relationship NDA. Templates for them are now sold online, and they are worth discussing precisely because they mark the line where an agreement stops protecting two people and starts protecting one.

A confidentiality clause covering business information, a company one partner runs, a client list, an unannounced venture, is ordinary and reasonable. A clause designed to buy silence about how someone was treated is a different object wearing the same name, and courts across common-law jurisdictions have grown steadily less willing to enforce agreements that suppress disclosure of harm.

The test is simple and worth stating plainly: an agreement between equals protects both of them. If a clause only ever protects one, it is not a mutual clause.

There is a genre of pre-commitment checklist circulating online now, the best known being a fifty-two step list aimed squarely at men. Strip away the tone and a surprising amount of it is sound. It tells you to be financially independent before you commit. To clear your debt and know your credit position. To learn your jurisdiction’s family law before you are governed by it. To sit in a family courtroom for an afternoon and watch what asset division actually looks like. To live together with real bills before deciding anything. To notice how someone behaves when they hear the word no.

Those are good instructions. Most people do none of them.

But the list has a structural flaw, and it is not the one critics usually reach for. The flaw is that it runs in one direction. It is a man assembling a file on a woman: hire an investigator, pull her credit report, interview her ex over a beer, watch her when she is angry or drunk.

Why one-directional fails on its own terms

Set the ethics aside for a moment and look at it as an engineering problem, because that is where it actually breaks.

First, some of it is not legal here. In Canada you cannot lawfully obtain another adult’s credit report without their consent; consumer reporting agencies require a permissible purpose and the Privacy Commissioner has found against organizations that collected reports without it. A step you cannot legally take is not a step.

Second, and more decisively: covertly gathered information cannot hold up an agreement. Canadian courts set aside domestic contracts for one informational failure above all others, and it is not insufficient investigation. It is non-disclosure. In Rick v. Brandsema the Supreme Court held that full and honest disclosure is fundamental to the fairness of any domestic contract. Ontario’s Family Law Act s. 56(4) lets a court set a contract aside where a party failed to disclose significant assets, debts or liabilities, and even innocent omissions have been held to breach the obligation.

So the man who runs the full surveillance programme and then signs an agreement built on what he found still holds a document a court can void. The couple who sat at a kitchen table and put every asset, debt, student loan and contingent inheritance on paper, each with their own lawyer, holds one that stands.

That is the whole modernisation. Keep every hard question. Ask it in both directions, out loud, on the record.

Four stages, both people

1. Arrive as a whole person

   Each of you has lived alone and run a household. Each can cook, budget and handle a bill. Consumer debt cleared or on a plan you both know about. Income you personally control. Interests that survive the relationship ending.

   The original framed this as one person becoming worthy of the other. The data says otherwise: 54% of Canadians report being financially dependent on a partner. Dependence is a household condition, not a gendered one.

2. Learn the law you are already under

   Both of you find out what your province does automatically, and on what date. Both of you get independent legal advice, from separate lawyers. Spend an afternoon in a family court building and watch a division of assets happen to strangers.

   The original had this right and it is the most useful item on its list. Independent advice for each party is also a factor in whether an agreement survives challenge, so this stage is not optional.

3. Disclose. Do not investigate.

   Assets, debts, student loans, credit position, income, obligations to children or parents, business interests, pensions, and contingent things like inheritances or stock options. Documented, not described. Both directions, same day.

   This is the stage the original gets exactly backwards, and the law is why. Everything the investigation was trying to discover, disclosure obtains lawfully, in usable form, and with the other person’s knowledge — which is the only version a court will respect.

4. Test the ordinary days

   Live together with real bills before deciding. Watch how each of you handles a no, a budget, an inconvenient in-law, a bad week. Spend real time with couples five and fifteen years ahead of you, with children and without.

   Kept almost intact from the original, which understood that the courting version of a person tells you very little.

Two of the original stages do not survive translation, because they are about one person’s preparation for a dating market rather than two people’s preparation for a binding contract. Nothing in this framework asks about anyone’s history in bed.

The same questions, rewritten

The old question was is she safe to marry. It is a reasonable question and it has an obvious problem: she is asking it too, and the version of you she is evaluating is the one who hired the investigator.

The modern question is smaller and much harder. Are we two people capable of writing down what we have agreed to, and signing it in front of each other? Couples who can do that do not need a private investigator. Couples who cannot have their answer.

Everything above resolves to one sentence.

That is the gap, and it produces three distinct kinds of value.

One — it replaces an inherited default with a chosen one

The current default was drafted by a provincial legislature for a household model that a minority of Canadians now live in, and it applies automatically on a date nobody observes. Whatever two people would decide for themselves, the case for deciding it is that the alternative is not neutrality. The alternative is someone else’s decision, applied silently.

Two — it forces the conversation while both people are still generous

The financial terms of a relationship get worked out either at the beginning or at the end. At the beginning, both people are generous, hopeful, and inclined to be fair to each other. At the end, they are frightened and advised by separate lawyers. The terms reached in those two rooms are not the same terms, and 37% of separated Canadians can tell you what it costs to find that out late.

Three — it makes invisible contribution visible

The satisfaction gap in section five, 88.4% against 76.3%, exists because unpaid contribution is genuinely hard to see from the inside of a household. Writing it down is the only mechanism that reliably converts it from something one person feels into something both people acknowledge. That is worth doing even if the couple never separates — arguably especially then.

The framing that matters is the last one. This is not a document about how a relationship might end. It is a document about how it is actually running, and the reason to write it now is that both people currently want the other one to be treated well.

The same clause as the one at the top of this page. The only difference is who wrote it.

None of these have a clean answer. That is the point of including them.

1. If a two-year clock is already running on half of what you own, should the province be required to tell you it started?
2. Is equal division still the fairest default when both people earn, or is it a rule from a one-earner era being applied to a two-earner country?
3. Thirty-three percent moved in together for financial reasons. Does economic pressure make consent to a property regime less real?
4. Who does the current default actually protect — and is that the same person it was written to protect in 1997?
5. If 88.4% of men and 76.3% of women call the same division of housework fair, whose reading should the agreement be written from?
6. Is there any question on a one-directional vetting checklist that becomes worse when both people have to answer it?
7. Where exactly is the line between a confidentiality clause that protects a business and one that buys silence?
8. Would you rather negotiate the terms of your relationship in year one, or discover them in a courtroom in year nine?
