Unless you have signed a cohabitation agreement, common-law spouses generally have fewer legal rights than married spouses upon break-up of a relationship. Under the Ontario Family Law Act, a couple is considered to be living in a common-law relationship:
- if they have been living together intimately for at least three years, or
 - if they have been living together for less time but they have a child together.
 
The end of a relationship involves serious legal and financial matters which must be negotiated and finalised. To get help, ask a lawyer now.
Property rights common-law spouses do not have
There are two important property rights which married spouses have if they separate which common-law spouses do not have:
- Common-law spouses do not each have an equal right to live in the family home, unless they are both owners.
 - Common-law spouses do not have an automatic right to equalize their net family property acquired during their relationship.
 
In most cases, both the family home and other property go to the person who is the owner. Each person usually keeps everything they personally own and nothing more.
There are two equitable remedies, unjust enrichment and constructive trust, that a common-law spouse may use to bring a claim for a share in property owned by the other common-law partner.
Rights common-law spouses do have
Although there are some rights that married spouses have that common-law spouses do not have, common-law spouses do have some important rights under the law. These include
- child support,
 - spousal support, and
 - rights to CPP pension credits.
