Manitoba marriage contract research: The Family Property Act, C.C.S.M. c. F25. Unmarried default: spouse like after trigger.
Manitoba has its own marriage-contract pack. Manitoba marriage contract research: The Family Property Act, C.C.S.M. c. F25. Unmarried default: spouse like after trigger. This is not a U.S. prenup and it is not a neighbouring province’s statute with the names swapped.
Manitoba also has a cohabitation-agreement pack. Unmarried partners can fall inside family-property legislation after a statutory trigger such as time or a child. This pack is the cohabitation track. Do not treat it as a marriage contract or as Swedish samboavtal.
The two instruments stay apart on purpose. A file titled prenup still has to be classified as a marriage contract or a cohabitation agreement based on whether the parties are married, about to marry, or unmarried, and on Manitoba form.
marriage contract
Spouses may make agreements about family property in writing according to the Act. Formality is provincial, not UPAA.
Spouses may make agreements about family property in writing according to the Act. Formality is provincial, not UPAA.
Family assets / family property under Manitoba’s Act is its own accounting, not BC excluded-property and not Québec patrimony.
A marriage contract typically addresses property, debts, and sometimes support between spouses. Public-order limits (Québec family patrimony; child support everywhere) still apply.
Support is a separate Manitoba/federal analysis from property contracting.
Child support is not a bargained-away private debt between adults.
The Act and general contract principles govern when an agreement will not be followed. Disclosure and advice remain lawyer questions.
Canadian family agreements are often judged partly on whether each party knew the assets and debts. This pack does not invent a U.S. statutory disclosure exhibit list.
Do not generalize Manitoba’s three-year common-law trigger to Ontario or Québec.
Canadian family agreements often stand or fall partly on whether each party could get advice. That is not a uniform statutory certificate across provinces, and Québec notarial counseling is a different professional model from common-law ILA letters.
A first draft delivered immediately before a wedding is a voluntariness and understanding fact. Canada does not use a single U.S.-style statutory waiting period in these packs.
cohabitation agreement
Common-law partners who meet the Act’s definition may also contract about family property. Do not use Ontario s. 53 numbering.
Common-law partners who meet the Act’s definition may also contract about family property. Do not use Ontario s. 53 numbering.
Manitoba’s Family Property Act can include common-law partners after a three-year cohabitation (or a registered common-law relationship, or a child plus a relationship of some permanence, as the Act defines). That is not Ontario’s married-only equalization.
A cohabitation agreement typically addresses property and debts between unmarried partners. It cannot manufacture a statutory regime the province does not confer, and it cannot replace a will.

A cohabitation agreement signed years into a relationship, or a 'prenup' signed while unmarried just before a wedding, raises classification and transition questions. Marriage usually moves the couple onto the marriage-contract / marital-property statute.

Worked examples
The useful question is whether it is a marriage contract or a cohabitation agreement given the parties’ status. Manitoba sources are the only citations this page will use.
Ontario equalization language, British Columbia excluded-property language, and Québec family-patrimony language are not interchangeable. Do not generalize Manitoba’s three-year common-law trigger to Ontario or Québec.
