Copy and paste from some website on BC Family law.
The basic principles of the Family Law Act
The law about dividing property and debt is contained in the Family Law Act. In general:

Each spouse is entitled to keep the property they brought into the relationship, plus certain kinds of property received during the relationship, like inheritances and court awards, as his or her “excluded property.”

Each spouse is entitled to one-half of the property acquired during the relationship, including any increase in value the spouses’ excluded property. The property the spouses are entitled to share in is called “family property.”

Each spouse is liable for one-half of the debt incurred during the relationship, including any debt incurred after separation to maintain family property. The debt the spouses are obliged to share is called “family debt.”

How does that work for things like a mortgaged house though? ie. I bought it before we were common law, once we became common law we both started paying for it.
