Built for Provincial Review
Ontario
Ontario’s Family Law Act permits spouses to make a marriage contract during marriage and sets writing, signing, witnessing, disclosure, and court-review rules.
British Columbia
British Columbia’s Family Law Act addresses property and support agreements and the circumstances in which a court may set one aside.
Alberta
Alberta’s Family Property Act requires separate lawyer acknowledgments for an agreement contracting out of statutory property rights.
Saskatchewan
Saskatchewan interspousal contracts require witnessed signatures and separate written acknowledgments before different lawyers.
Quebec
A Quebec marriage contract or change of matrimonial regime requires a notarial act and the notices or registration required by the Civil Code.
Frequently Asked Questions
What is a postnuptial agreement in Canada?
A postnuptial agreement is a domestic contract spouses make after marriage. Depending on the province, it may address property, debts, support, estate-related rights, business interests, and other financial arrangements, subject to mandatory law.
Is a postnup enforceable in Canada?
Canadian provinces permit spouses to make domestic agreements during marriage, but enforceability depends on the governing legislation, financial disclosure, informed consent, fairness considerations, legal advice, and signing formalities. A lawyer should review the final document.
Can we create a postnup if we are separating?
This Prenuply workflow is for married couples who remain together. Couples already separated or negotiating divorce should get advice about a separation agreement or the appropriate legal process.
Do both spouses need separate lawyers?
Separate independent legal advice is strongly recommended. Alberta and Saskatchewan also require separate lawyer acknowledgment formalities for certain property agreements. Each spouse should understand the rights being changed before signing.
What happens in Quebec?
A Quebec marriage contract or change of matrimonial regime must follow Civil Code formalities, including a notarial act and required registration or notice. A privately signed Prenuply template is not a substitute for the notarial act.
Can a postnup replace our prenup?
It can potentially amend or replace an earlier agreement, but the earlier document must be reviewed and the new wording must state the intended relationship between them clearly. Give both documents to your lawyers.
