A De Facto Spouse in Quebec, and What Changed

Quebec attaches no property regime and no support obligation between spouses to a de facto union, however long it has lasted and however the household divided its paid and unpaid work. Where the residence, the registered plan and the pension stand in one partner's name, a separation leaves them there. The 2025 reform changed less of that than the headlines said, and what it did change is written in articles anyone can read.

This page sets out what a conjointe de fait in Quebec actually holds, what a married spouse holds instead, what the parental union regime created on 30 June 2025 and what it deliberately left outside, and where a life insurance contract sits. Every legal question raised here belongs to a Quebec notary or a family lawyer, and naming the mechanisms is how a conversation with one of them starts further along.

What is a de facto spouse in Quebec, and what does she not have?

A de facto spouse is somebody who lives with a partner as a couple without marrying and without entering a civil union. Quebec attaches no property regime and no support obligation to that status. On separation she cannot claim spousal support for herself, the family patrimony, or a share of the other's registered plan or pension.

The list of what is absent is short and it is complete. Educaloi states it without qualification: de facto spouses have no right to spousal support on separation, no right to a division of property, and no inheritance where the other dies without a will. The family residence protections attaching to marriage do not attach either, where the other partner is sole owner or sole tenant.

Child support escapes all of this, and the distinction is worth holding onto. Support owed to a child follows the child and not the relationship between the parents, so it is owed on the same terms whether they married, entered a civil union or formalised nothing. What disappears is the support she could claim for herself.

What remains is real and it is harder work. A claim in unjust enrichment, a tacit partnership, and an agreement signed while both partners still agree. Each route needs evidence, a lawyer and time, and none arrives automatically the way a family patrimony arrives on the day of a marriage.

What did the Supreme Court of Canada decide in 2013?

It upheld the Quebec position. In Quebec (Attorney General) v A, 2013 SCC 5, decided on 25 January 2013 by five judges to four, the Court held that confining spousal support and the division of family property to married and civil union couples is constitutionally valid. De facto spouses were left where the Civil Code of Quebec had put them.

The narrowness of that margin is part of the fact and belongs on the page. The Court divided repeatedly, first on whether the exclusion drew a distinction that discriminated at all, then on whether such a distinction could be justified, and the result that stood was reached by a single vote. Anyone assuming the law here is comfortably settled is reading a five to four outcome.

The reasoning that carried the day rested on consent. Quebec treats marriage and civil union as regimes people enter deliberately, with the obligations attached to that choice, and treats the de facto union as the relationship of two people who did not make that choice. No later statute has displaced the part of the decision governing spousal support.

The consequence for a woman planning around it is unsentimental. Her position on separation is the position the Civil Code of Quebec gives her, and the Supreme Court of Canada has already been asked to change it and declined. Anything better than that has to be built by agreement, by ownership or by contract, before the day it is needed.

What does a married or civil union spouse have instead?

The family patrimony, and its contents are the whole contrast. Article 415 of the Civil Code of Quebec places into it the family residences, the furniture serving the household, the motor vehicles used for family travel, the rights accrued during the marriage under a retirement plan, and the earnings registered under the Act respecting the Quebec Pension Plan.

Read that list twice, because the last two items decide a retirement. A married spouse who left paid work holds a claim on what the other built inside a registered retirement savings plan and inside an employer pension during the marriage, and on the employment earnings the public plan recorded. Those are usually the largest assets the household owns.

Partition is in value and not in kind, which surprises people. Nobody is automatically entitled to the house itself; the patrimony is valued and one spouse pays the other. Property received by succession or by gift sits outside it, along with everything else a married couple owns that the article does not name, including a private company and a non registered portfolio.

Spousal support is a separate question again and runs on its own principles. A married or civil union spouse can claim it; a de facto spouse cannot. Two households on the same street, with the same children and the same division of labour, can end in two entirely different places because of a document one of them signed and the other did not.

How many Quebec couples does this actually describe?

More than four in ten. At the 2021 Census, Statistics Canada reported that 43 percent of couples in Quebec were living common law, against 23 percent across Canada. This is not a marginal arrangement.

The second figure in that release turns a statistic into a situation. Common law couples in Quebec were more likely to have children living at home, 49 percent of them, than married couples in Quebec at 45 percent, and Statistics Canada notes that the pattern has held since 2011 and is unlike the rest of the country.

Put those two together and the shape of the audience appears. A large share of Quebec families with children at home is headed by two people with no property regime between them, no support obligation between them and, before 30 June 2025, no succession rights between them.

The scale also explains why the reform happened and why it stopped where it did. A regime reaching every de facto couple would have rewritten the choice the 2013 decision protected. A regime reaching only couples who become parents together is narrower, and its contents were drawn narrowly too.

What did the parental union regime create on 30 June 2025?

A patrimony, and only for parents. Under article 521.20 of the Civil Code of Quebec a parental union forms as soon as de facto spouses become the parents of the same child, and article 521.29 provides that the union creates a parental union patrimony out of certain property of the spouses, regardless of which of them owns it.

The regime applies automatically where the child is born or adopted on or after 30 June 2025, the couple live together, and they present themselves publicly as a couple. That date is a hard edge. A couple whose youngest child was born in 2024 sits outside the regime by default, and a couple whose youngest arrived in 2026 sits inside it without signing anything.

Couples already parents before that date can join deliberately. The Government of Quebec states that they may form a parental union on a voluntary basis in one of two ways, by notarial act or by written contract signed in the presence of two witnesses. A notary is the person to ask what each route costs and what each one covers.

The regime can also be left. Article 521.33 allows spouses during the union to withdraw from it by common agreement, by notarial act in minute, on pain of absolute nullity. That formality is not an ornament; it is how the law makes giving up the patrimony a deliberate act done in front of somebody who explains it.

What does the parental union patrimony leave out?

Retirement savings, pensions and salary. Article 521.30 composes the patrimony of the family residences or the rights conferring their use, the furniture that furnishes them and serves the use of the household, and the motor vehicles used for family travel. Nothing else is in it, and the Government of Quebec says so explicitly about retirement plans.

This is the reason this page exists. A woman who reduced her earnings for fifteen years to raise children is poorer in exactly one place: the registered retirement savings plan she did not fill, the employer pension she did not accrue and the contributory record she did not build. The regime reaches the house, the couch and the car, and leaves every one of those intact.

The Government of Quebec draws the contrast with marriage itself. Unlike marriage, it says, the patrimony does not include the rights one spouse has vested in a retirement plan such as a registered retirement savings plan, and unlike marriage it does not include the earnings registered under the Act respecting the Quebec Pension Plan. Cash, accounts and investments are outside as well.

So the arithmetic runs in the wrong direction for the person who gave up the income. The residence is usually mortgaged and shared in value, while the pension is usually unencumbered and stays whole with the person who earned it. Anyone relying on the regime to protect a retirement should read article 521.30 once and then telephone a notary.

Does a spouse in a parental union inherit without a will?

Yes, and an ordinary de facto spouse does not. Article 653 of the Civil Code of Quebec now devolves a succession to the surviving spouse who was bound to the deceased by marriage, by civil union or by parental union. Article 666 gives that spouse one third of the succession where there are descendants, who take the other two thirds.

Before that amendment the answer was simply nothing. A de facto spouse of thirty years whose partner died without a will received no part of his estate, and the property went to the children or, failing them, further along the line of relatives the Code sets out. Educaloi still states the general rule for de facto spouses in exactly those terms.

The inheritance right therefore tracks the same date as the patrimony. A couple inside the parental union regime has it; a couple outside it does not, whatever their circumstances, and the couple outside it includes everybody whose youngest child arrived before 30 June 2025 and who has not joined by notarial act or by written contract before two witnesses.

A will settles the question for either couple and costs less than the litigation it avoids. It is the document here that a person can put in place without the other partner's agreement, and it operates whether or not the regime applies. A notary drafts it, keeps it and registers it, which makes it the first appointment rather than the last.

What is a compensatory allowance, and what is it not?

It is compensation for enrichment, awarded once, and it is not spousal support. Article 521.43 of the Civil Code of Quebec allows a spouse, from the end of the parental union, to ask the court to order the other to pay compensation for the impoverishment she suffered through a contribution in property or services that enriched his patrimony.

The proof is open and the burden is real. Article 521.44 provides that the impoverishment of one spouse and the contribution to the enrichment of the other's patrimony may be proved by any means, which is generous as to method and says nothing about how much persuading a court takes. Records, dates and figures do that work.

What the allowance is not matters as much as what it is. It is not a periodic payment that continues while she rebuilds an income, it is not indexed, and it does not arrive because the relationship lasted a long time or because the division of labour was unequal. It answers a narrow question about enrichment, and the answer is a sum.

The parental union regime did not create spousal support between de facto spouses in Quebec, and nothing on this page should be read as saying it did. The 2013 decision still governs that question. Anybody whose plan depends on the point should have it confirmed in writing by a Quebec family lawyer, against the text in force on the day.

What can a cohabitation agreement do that the law does not?

It can create by contract most of what the law withholds. Educaloi describes a contrat de vie commune as the instrument through which de facto spouses can provide for a division of property, a compensatory payment or support, which are protections Quebec law does not otherwise give them. It can also allocate financial contributions and debts.

The limits are specific and a notary will name them. An agreement cannot provide that no support will be paid for a minor child, cannot transfer property on death in place of a will, and cannot contain terms contrary to the interests of the children. Those three exclusions are where homemade agreements usually fail.

Form matters less than people expect and timing matters more. Educaloi notes that no notary is legally required for such an agreement, while recommending professional help anyway. The concrete difficulty is never the drafting; it is that the agreement has to be signed while both partners still want the other one protected.

For a couple already inside the parental union regime, an agreement does different work. It can add what article 521.30 leaves out, name the registered retirement savings plan and the pension, and record what each partner contributed. For a couple outside the regime it carries almost the whole weight, and it earns an appointment before it is needed.

How is the Quebec Pension Plan partition different for a de facto spouse?

It exists, and it is not automatic. Retraite Québec partitions the employment earnings recorded during a marriage or civil union automatically when a Quebec judgment is rendered, unless the former spouses expressly renounced it. For de facto spouses there is no automatic partition, and a joint application must be filed within four years after the separation.

Two features of that sentence cost money. A joint application needs the other person's signature, which is what somebody who has just left a relationship may be unable to obtain, although Retraite Québec allows one former spouse to file alone where a written and signed agreement provided for it. And four years passes quickly while a household is rebuilt.

The partition itself is worth more than most people assume. It divides the employment earnings on which contributions were paid during the union, which rewrites both contributory records rather than moving a monthly payment, and for a mother whose own record is thin from caregiving years it can change the pension she receives for the rest of her life.

Retraite Québec also states plainly that renouncing partition of the family patrimony is not renouncing partition of the employment earnings recorded under the Quebec Pension Plan. That sentence exists because people have signed away one believing they were signing away both. Ask Retraite Québec for the figures before anybody signs.

What does the Code decide about ownership and a designation?

Two things, and neither of them is a recommendation. Article 2457 of the Civil Code of Quebec does not reach a de facto spouse, and article 2449 leaves a designation naming her revocable by default. Who owns a contract and whether a designation is revocable are the two facts that decide whether she is told when either of them changes.

Article 2457 of the Civil Code of Quebec exempts the rights the contract confers from seizure where the designated beneficiary is the married or civil union spouse, a descendant or an ascendant of the policyholder or the participant. A conjointe de fait is not on that list, and twenty years together, three children and a shared mortgage do not put her on it.

The designation is the other half of the subject. Article 2449 makes the designation of a married or civil union spouse irrevocable unless the contract stipulates otherwise, so the designation of a de facto spouse is revocable by default. The owner can change it tomorrow, alone, and she would learn of it after the death. What a divorce does to a designation elsewhere in Canada is set out on divorce and the designation nobody changed.

Ownership and revocability are separate questions and the Code answers them separately. An owner can surrender a contract, let it lapse or replace a designation, and a revocable beneficiary receives notice of none of those acts. An irrevocable designation removes those powers from the owner and requires the named beneficiary's written consent before anything changes. Which arrangement, if any, fits her file is a question for a notary against her own documents, and it is not settled on this page.

State the limits in the same breath. Insurance is insurance and it is not an investment. Term life insurance covers a defined number of years at a lower cost and accumulates nothing, while a participating whole life insurance contract is permanent and builds a cash surrender value; participating policyholder dividends are not guaranteed and the dividend scale can be changed by the insurer. A death benefit creates no property claim and no support right.

Who this suits, and who it does not

It suits a woman in Quebec living as a conjointe de fait, who has reduced her own earnings for the household, and who wants to know what she holds before she needs to know it. It suits her most where the house, the registered plan and the pension stand in the other partner's name.

It suits a couple who became parents before 30 June 2025 and have not examined whether joining the parental union regime would change anything for them. A notary can price the notarial act and the written contract before two witnesses, and say what each reaches and what article 521.30 still leaves outside.

It applies with less force to a married or civil union spouse in Quebec, who already holds the family patrimony, the retirement plan rights inside it and a support claim. It does not apply to a couple in British Columbia or Ontario, where the treatment of unmarried couples runs on other statutes and produces other answers.

It does not suit anybody looking for a contract before the position has been read. The order here is documents first: the deed, the plan statements, the designations and the children's dates of birth. Where the four priorities set out on financial sovereignty for women are still open, a contract is not the next step.

Nothing here is legal or tax advice, and the practice gives neither. Quebec family law questions belong to a notary or a family lawyer, pension questions to Retraite Québec, tax questions to your accountant, and suitability for any contract depends on facts this page does not have. Participating policyholder dividends are not guaranteed and guarantees rest on the claims paying ability of the issuing insurer.
