For many family law litigants, the final decision is not the end of the case. Increasingly, one of the most significant issues comes afterward: costs.
While clients often focus on parenting arrangements, support obligations, or property division, the financial consequences of litigation conduct can be substantial. A costs award may represent thousands or even tens of thousands of dollars and can dramatically alter the practical outcome of a case.
Ontario’s Family Law Rules start with a simple presumption: the successful party is generally entitled to costs. But determining who was successful, whether success was divided, and how much should ultimately be paid is rarely straightforward.
Modern costs principles serve several important purposes. Courts have repeatedly recognized that costs are intended to partially indemnify successful litigants, encourage settlement, discourage inappropriate behaviour, and help ensure cases are resolved justly. These objectives have become increasingly important as family law proceedings grow more complex and expensive.
The message from recent decisions is clear: litigation conduct matters.
Parties who fail to provide disclosure, advance unreasonable positions, ignore settlement opportunities, or unnecessarily increase the complexity of proceedings risk significant costs consequences. In some circumstances, courts may award full recovery costs where a party has acted unreasonably, behaved in bad faith, or rejected a reasonable offer to settle only to achieve a worse result at trial.
Settlement offers, in particular, continue to play a critical role. Family law practitioners should view offers to settle not simply as negotiation tools, but as strategic litigation documents that may ultimately determine the outcome of a costs award. Courts regularly examine whether a party achieved a result equal to or better than a previous offer and whether opportunities existed to resolve disputes earlier.
The growing focus on proportionality is equally important. Courts are increasingly scrutinizing legal fees, lawyer staffing, expert costs, and the overall reasonableness of expenses incurred. A successful party is not automatically entitled to recover every dollar spent. Rather, the court’s objective is to arrive at a fair, reasonable, and proportionate amount in the circumstances.
Perhaps the most important lesson for family law litigants is that costs are no longer a secondary issue. They are part of the litigation strategy from day one.
Good advocacy today means more than winning legal arguments. It means making reasonable settlement efforts, maintaining professional conduct, focusing on proportionality, and helping move cases toward resolution. Those who fail to do so may discover that the most expensive part of their family law case is not the dispute itself, but the costs consequences that follow.
As courts continue to emphasize efficiency, reasonableness, and access to justice, costs awards will remain one of the most powerful tools available to shape litigation behaviour and encourage meaningful settlement.
