When you're going through a family law case, your own legal fees are a primary concern.
But what if you also had to pay a portion of your ex-partner's legal bill? In British Columbia, this is a real possibility, and it's a concept called "costs."
Understanding how costs work is crucial because it can dramatically affect the financial risk of your case. The rules are completely different depending on which court you are in.
What Exactly Are "Costs"?
In a lawsuit, costs are a sum of money the unsuccessful party is ordered to pay to the successful party. This isn't meant to be a punishment. Instead, it’s a way to partially reimburse the winner for the legal expenses they had to pay to get a fair result.
It’s important to know that costs usually don't cover the entire lawyer's bill. They are calculated based on a tariff in the court rules and are designed to promote fairness and discourage unreasonable behaviour in litigation.
The Big Difference: Supreme Court vs. Provincial Court
The most important factor in determining costs is the court your case is in.
BC Supreme Court: Costs Are the Norm
In the Supreme Court of British Columbia, there is a clear default rule: the winner gets their costs.
The Supreme Court Family Rules (Rule 16-1(7)) state that costs must be awarded to the successful party unless the judge specifically orders otherwise. The goal, outlined in Rule 1-3(1), is to encourage cooperation and minimize expensive, lengthy court battles.
The court's intention is to guide how people approach their lawsuit. As noted in the case of Karpodinis v. Kantas, the rule on costs exists to encourage reasonable choices and strategies. If the winner wasn't awarded their costs, there would be less incentive for parties to act reasonably.
BC Provincial Court: No Costs in Family Law
In the Provincial Court of British Columbia, the opposite is true for family law matters. Costs are not typically awarded to either party, regardless of who wins. This court is designed to be more accessible, especially for self-represented litigants, and removing the risk of paying the other side's costs is a key part of that accessibility.
How Does the Supreme Court Decide Who "Won"?

Winning in court isn't always a clear-cut victory on every single point. For things like interim applications (governed by rules like 10-1 and 10-5), the court uses the "substantially successful" test.
As explained in Rattenbury v. Rattenbury, a judge won't go through every minor detail. Instead, they will:
Look at the major, substantive issues in dispute.
Assess how much success each party had on those key issues.
Determine who was more successful overall.
Think of it like a sports match: you don't have to win every single play to win the game. The party who wins on the most important issues is considered "substantially successful" and will likely be awarded costs.
Frequently Asked Questions (FAQ)
Q: If I win my case in Supreme Court, will my ex have to pay my entire legal bill?
A: No, almost certainly not. "Costs" are a partial reimbursement based on a set scale (the tariff). They are not a full repayment of your lawyer's fees.
Q: Can a judge in Supreme Court of British Columbia decide not to award costs even if I win?
A: Yes. The judge has the final say. If the judge feels that the "successful" party acted unreasonably, prolonged the conflict, or was unsuccessful on several key issues, they can choose to award them only partial costs or no costs at all.
Q: Why do these rules exist?
A: The risk of having to pay costs in Supreme Court is a powerful incentive. It encourages parties to make reasonable settlement offers, focus on the real issues, and avoid bringing unnecessary applications to court, which saves everyone time and money.
The court you choose for your family law matter has significant financial implications. While the Provincial Court removes the risk of a costs award, the Supreme Court uses that very risk to manage behaviour and encourage efficient resolutions.
Your conduct throughout the legal process matters.
Being unreasonable or refusing to cooperate can have a direct financial consequence in the Supreme Court. Always discuss the potential for a costs award with your family lawyer before starting or responding to a court action.
