Family Debt Does Not Mean Debt Owed to A Third Party

Lan v. Buchanan clarifies the boundary between family-law allocation and a creditor's contractual rights

On September 4, 2026, the Court of Appeal for British Columbia released its decision in Lan v. Buchanan, 2026 BCCA 370. The Court clarified the legal meaning of “family debt” and the important distinction between allocating debt between spouses and establishing a third party's contractual right to payment.

The decision is important for both family and civil litigation because the same financial obligation may have different consequences in the relationship between former spouses and in the relationship between a creditor and an alleged debtor.

Facts

The plaintiff, Mrs. Buchanan, is the former mother-in-law of the defendant, Ms. Lan, who was in a common-law relationship with Mrs. Buchanan's son, Mr. Buchanan, until 2019.

A family-law trial between Ms. Lan and Mr. Buchanan took place in 2023 and 2024. The trial judge found that several advances made by Mrs. Buchanan were loans rather than gifts and classified them as family debt under the Family Law Act. The loans totalled nearly $500,000. At least one written loan agreement was between Mrs. Buchanan and her son, and Ms. Lan was not a party to it.

The trial judge apportioned responsibility for the family debt between the former spouses, generally equally but subject to an adjustment concerning interest on one loan.

The Civil Case

Mrs. Buchanan later commenced a separate civil action against Ms. Lan, seeking $248,120.60. Her debt claim relied primarily on the earlier family-law order and the amount of family debt allocated to Ms. Lan.

Mrs. Buchanan applied for summary judgment, a procedure that may allow a court to decide a claim without a full trial where there is no genuine issue requiring a trial.

The chambers judge concluded that the family-debt order provided an unrefuted basis for the claim and granted judgment against Ms. Lan for the full amount sought.

The Appeal

The principal issue on appeal was whether the chambers judge erred in law by treating the family-debt order as giving Mrs. Buchanan a legal right to recover directly from Ms. Lan the amounts apportioned to her in the family proceeding.

The Court of Appeal unanimously concluded that this was an error. The concept of family debt is used to allocate financial responsibility between spouses. It does not determine whether a third party has a contractual right to recover from either spouse.

What the Court of Appeal Decided

A third-party creditor's right to enforce a debt does not change merely because the obligation has been classified and apportioned as family debt. The creditor's rights depend on the contract between the creditor and the alleged debtor, whether oral or written.

Where only one spouse is contractually liable for a loan that is later classified as family debt, that spouse remains solely liable to the creditor. The debtor spouse may have a right to contribution from the other spouse within the family proceeding, but that allocation does not itself make the other spouse liable to the creditor.

Accordingly, the family-debt order did not, by itself, create a creditor-debtor relationship between Mrs. Buchanan and Ms. Lan. Mrs. Buchanan could not rely on that order alone to establish her debt claim against Ms. Lan.

What Happens Next?

The Court of Appeal allowed the appeal, set aside the judgment requiring Ms. Lan to pay $248,120.60, and dismissed Mrs. Buchanan's summary-judgment application.

The Court did not dismiss Mrs. Buchanan's civil claim altogether. Whether she has a contractual basis for alleging that Ms. Lan was a party to some or all of the loans remains unresolved. The trial court may need to determine whether the claim should be struck or whether amendments, if requested, should be permitted.

Conclusion

Civil and family disputes can be closely intertwined, as Lan v. Buchanan demonstrates. However, a finding made to allocate responsibility between spouses does not automatically determine a third party's contractual rights. The pleadings, loan terms, parties to the agreement, and evidence must each be analyzed in their proper legal context.
