Common law spouses are still legally entitled to spousal support, as long as they qualify as spouses under the Family Law Act. This act outlines that all spouses, even common law, are able to receive support.
Common law spouses are defined as partners who have cohabited continually for at least 3 years or more. If you and your partner have a child together, you may also qualify as common law partners as long as your relationship was somewhat permanent.
