Common-law spouses are couples who have a family framework without marriage. Even members who have been living together for a long time can be considered common-law.
For married couples, the very fact of marriage is proof that the couple has a family framework and stops presenting the marriage certificate. However, the co-conspirators have the burden of proof to prove the connection, which requires witnesses who know the couple to show evidence of joint living or managing a common household or living together.
Recognition of a common-law couple entails the possibility of enjoying rights from which couples enjoy subjects such as food or property sharing.
