Family Law and Definition of Common Law Spouse

Header Image If you live with someone without being married, then you may be in a common-law relationship.  There is no single definition for common-law spouse as the definition changes depending on the reason you are asking the question.

Income Tax & Real Estate

For example, for income tax reasons, section 248(1) of the Federal Income Tax Act defines a common-law partner as a person who cohabits in a conjugal relationship with another person and:

  1.      Has so cohabited with the other person for a continuous period of at least one year, or
  2.      Would be the parent of an adopted or natural born child with the other person.

Family Law

However, for spousal support reasons in Family Law, section 29 of the Ontario Family Law Act defines “spouse” to include either of two persons who are not married to each other and have cohabited:

  1.       Continuously for a period of not less than three years, or
  2.       In a relationship of some permanence, if they are the natural or adoptive parents of a child.

For Family Law reasons – including spousal property rights, spousal support, etc. – it is crucial that you know the correct definition of common-law spouse before you make any decisions and/or sign any cohabitation or separation agreement.  One fundamental distinction between married and common-law spouses is that couples who live together DO NOT have the same rights as married couples to a share in the value of property, including the home they live in, unless the property is in both of their names.

Without a cohabitation agreement, a common law spouse may need to file a court application to assert his or her claim against the common-law spouse’s property using “equitable relief” claims – such as constructive and resulting trust claims.  In my opinion, these claims are expensive to pursue, difficult to make out and still do not guarantee that you will receive your fair share of the value of the property in question.

If you are thinking of living with somebody or are already in a common-law relationship, contact us to discuss ways that you can both protect yourselves, your assets and your children, if your relationship was to breakdown in the future.  Separation is a challenging and difficult event and most people do not want to think about it; but you owe it to yourself and your children to plan for the future to ensure you will be financially secure.
