Family Law Arbitration Appeal BC: Expert Insights

In the recent past and British Columbia, there has been a major shift in family law toward mediation and arbitration because people do not want their savings, privacy and frankly ‘dirty laundry’ to be subject to public court proceedings.

Yet as more families choose this path, questions about the family law arbitration appeal process are becoming just as important as the arbitration itself. Parties want privacy. They want efficiency. They want better cost control. Most importantly, many families recognize that deeply personal decisions should not always be left to the traditional court system.

Family law litigation often places families in front of a judge who may only see a small part of the bigger picture. A judge may not fully understand the family dynamics, the emotional history, or the practical realities that shape long-term outcomes. In good faith, many parties now choose arbitration because it is often faster, more practical, more private, and more tailored to their family’s needs.

However, one challenge arbitration sometimes faces is perception. Because arbitration is not viewed by some parties as being as “official” or as powerful as a court order, parties who are unhappy with the outcome often try to appeal the result to the courts. They may believe that if arbitration does not go their way, court is the backup plan.

What Happens When You Appeal a Family Law Arbitration in BC?

British Columbia courts have been very cautious about arbitration appeals. By way of policy, courts do not want parties using litigation as a second kick at the can. If arbitration becomes nothing more than a trial run before court, the entire purpose of the process is lost.

This area of law continues to evolve. One of the most recent and important decisions is Kohut v. Yagelniski, 2026 BCSC 714, decided by the BC Supreme Court on April 21, 2026.

This case is significant. It is one of the most comprehensive judicial analyses of last best offer arbitration in BC family law to date, and it contains lessons that matter whether you are a separating spouse, a family lawyer, or anyone thinking about using arbitration to resolve a divorce.

In Part 1 of this series, I explained what last best offer arbitration is and the key questions to ask before agreeing to it. In this article, I want to dig into the case itself and what it tells us about how BC courts will treat arbitration appeals going forward.

The Background of Arbitration Appeals Case: A High-Asset Separation With a Complicated History

The parties in this case – Olena and Dwain – had been together since 2006 and married in October 2007. They separated in July 2020 and have two children together.

A few facts about their situation:

They signed a marriage agreement three days before the wedding, while Olena had recently arrived from Ukraine, was not yet permitted to work in Canada, and was pregnant
Dwain had previously worked in the drilling industry internationally and retired in 2015
His interest in a real estate development company was held through a holding company, DYD Holdings , with real properties in Kelowna and Saskatchewan
Olena did not work outside the home after the parties married – she was the primary caregiver to the children for years while Dwain worked overseas
Their dream home at 5612 Mountainside Drive in Kelowna was under construction when they separated

How Did the Arbitration Proceed?

The parties began arbitration in July 2024 with a full week of hearings, including affidavit evidence and cross-examination. At the end of that week, the arbitrator proposed the last best offer process. The parties agreed.

They submitted their final offers on October 23, 2024. The arbitrator selected Dwain’s offer. Olena appealed on 14 grounds.

Why BC Courts Set a High Bar for a Family Law Arbitration Appeal

The single most important takeaway from this case is the court’s analysis of what is and is not reviewable when a party brings a family law arbitration appeal in BC — particularly where parties have agreed to last best offer arbitration without reasons.

The Court Had No Grounds to Intervene on Substance

Justice Wilson was direct about the fundamental problem: without written reasons, there is nothing to review on the substantive grounds.

The court cannot determine:

What findings the arbitrator made
What law the arbitrator applied
How the arbitrator weighed the evidence
Whether the arbitrator agreed or disagreed with any specific term

Olena’s appeal raised serious substantive concerns:

The family property was not divided fairly – by her calculation, Dwain retained approximately 75% of the personally held family property and 93% of the corporately owned property
She received no spousal support despite being a stay-at-home mother for the duration of the marriage
Dwain’s income for child support purposes was set at $246,000, despite his personal tax returns showing income of over $2.5 million in both 2022 and 2023

The court acknowledged these were real concerns. But it could not intervene. The arbitrator did not make findings, nor was he asked to. His job was to pick the fairer of the two offers based on the evidence he had heard. Without reasons, there is no path for an appellate court to say he got it wrong.

The Unenforceable Child Support Terms

One area where the court did take a clear position was the child support provisions.

The winning offer included terms stating that:

Dwain’s income for child support purposes would not exceed $246,000 for 2024 through 2027
The first review of child support would not occur until 2028

The court found these provisions unenforceable, following the 2018 BC Supreme Court decision in Chan-Henry v. Liu, which established that an agreement to fix child support and prevent variation is contrary to public policy.

Principles the court reaffirmed regarding Family Law and Arbitrations:

Child support is the right of the child, not a bargaining chip between parents
Parents have a joint and ongoing legal obligation to provide support commensurate with their income
A parent does not fulfil their obligation if they do not increase support when income increases significantly
An agreement that locks in support at a fixed level and prevents review is unenforceable

Did This Invalidate the Entire Award?

No. Section 19.20(2) of the Family Law Act provides that a provision inconsistent with the Act or the Divorce Act is simply not enforceable – while the rest of the award stands. Dwain’s counsel conceded he could not rely on those terms in any future variation application.

The practical effect: Olena retained the right to bring a child support variation application in the future, despite those paragraphs being part of the award.

The Procedural Fairness Issue: The Spreadsheet Problem

One of the most carefully analyzed sections of this decision involves a procedural fairness allegation that surfaced just before the appeal hearing.

Counsel for Olena discovered that the spreadsheets Dwain had sent to the arbitrator were not the same version that had been exchanged between the parties. The parties had been unable to agree on a reconciliation of their post-separation spending. On the day their offers were due, they agreed each would submit their own spreadsheets to the arbitrator.

Dwain sent nine spreadsheet tabs. Olena had expected only two.

The court held a continuation hearing specifically to investigate. It reviewed the full email chain from the day the offers were submitted.

The emails showed the following:

The parties had explicitly agreed, because they could not reach agreement, that each would submit their own spreadsheets
Counsel for Olena had written: “both parties will have to rely on their own spreadsheets with JP left to sort out how these numbers are included in each party’s offer”
Counsel for Dwain confirmed the agreement minutes later

The court then analyzed each of the additional spreadsheet tabs, asking whether any of them introduced materially new evidence that had not already been before the arbitrator.

What Did the Court Find on Each Tab?

The court’s conclusion: The modest changes, especially considering the overall amount of property divided, did not rise to the level of procedural unfairness.

Can a Party Submit a Final Offer More Favourable Than Their Opening Position?

Olena argued it was unfair for Dwain to include terms in his last best offer that were more favourable to him than his opening statement of relief.

The Court’s Answer: Yes, Parties Can Shift Their Positions

The court rejected both arguments. There was nothing in the agreed process that prevented either party from submitting a last best offer that differed from their opening positions.

The respondent’s explanation for the income increase was that his last best offer transferred a revenue-generating rental property to Olena, which would generate additional income for her. The court found this reasonable.

The switch to a last best offer process changed the nature of the proceeding. Parties are free to reassess and recalibrate their final positions.

The DYD Holdings Jurisdiction Argument

Olena argued the arbitrator exceeded his jurisdiction by making orders affecting DYD Holdings Ltd., because DYD was not a party to the arbitration agreement.

The court dismissed this quickly. DYD was:

Expressly named as a party on the first page of the arbitration agreement
Named as a respondent in the original family law proceeding

Additionally, Olena’s own last best offer had included terms directing DYD to take specific actions – including advancing $500,000 to her and transferring $3.4 million to her holding company. She could not argue DYD was not a party while simultaneously submitting an offer that required DYD to perform obligations under that same process.

What This Case Tells Us: Practical Lessons for Separating Spouses

Lesson 1: Last best offer arbitration is most appropriate when the record is complete

When the parties in this case switched to the last best offer process, they cancelled three planned days of evidence – including testimony from a business valuator. That incomplete evidentiary record was a significant theme throughout the appeal. The court could not know how unresolved factual disputes might have been decided.

Lesson 2: Waiving reasons means waiving substantive appellate review

The court was very clear about its limitations. It upheld an award that the judge herself described as potentially different from what a decision-maker hearing all the evidence might have reached. If you are not prepared to live with any outcome, do not waive reasons.

Lesson 3: Child support terms cannot be locked in by agreement

No matter what the arbitration award says, child support can always be varied. Terms that purport to prevent review until a future date are unenforceable. Both parties should understand this from the outset.

Lesson 4: Parties can change their positions from opening statements to final offers

The last best offer process is not bound by what either party said in their opening statement of relief. Each party submits their true final position. The switch to this process creates flexibility – but also risk.

Most Important Lesson 5: Process agreements will be enforced strictly

When the court analyzed the spreadsheet issue, it held the parties to the process they had agreed to. Parties should be very deliberate about every procedural decision they make – including how materials are exchanged and whether the other side will have any opportunity to respond.

Should You Use Arbitration to Resolve Your Family Law Dispute?

At YLaw, are very experienced family lawyers, mediators and arbitrators, Trudy Hopman and Lisa Newby have this to say about arbitration:

Arbitration – including the last best offer variation – can be an excellent choice for the right case. It is faster than court, more private, and can be tailored to your family’s specific needs.

But it requires strong legal advice throughout. The decisions you make about process – including whether to waive reasons, how to structure your evidence, and when to submit your final offer – can be just as consequential as the substantive outcome itself.
