Here is the Civil Code of Quebec: Don't leave home without it!
It sets out the general rules of law for the entire province, and unlike common law jurisdictions, we turn to the Civil Code first, before referring to case law for inspiration and guidance.
For all family proceedings which are not part of a divorce file, it is the Civil Code that applies: e.g. disavowal of paternity, separation as to bed and board, nullity of marriage, etc.
