Excluded Property Tracing

Excluded Property Tracing in BC

An exclusion under British Columbia's Family Law Act is only as strong as the paper trail behind it. The Act lets an inheritance, a gift, or an asset you brought into the relationship stay yours, and it lets that protection follow the money into new forms. But the Act also puts the burden of proof on you. Tracing is the work of building that proof, transaction by transaction, and it is some of the most document-heavy work we do.

SiLaw Group Family Lawyers is a boutique family law and mediation firm in South Surrey, practising family law only, in English and Punjabi. This page explains how we run a tracing exercise on a real file. For the rules themselves, including the full list of what qualifies as excluded property, see our guide to excluded property in BC.

Who Has to Prove an Exclusion in BC?

You do, if you are the one claiming it. Section 85(2) of the Family Law Act says a spouse claiming that property is excluded property is responsible for demonstrating that it is. Your spouse does not have to disprove anything. If the evidence is missing or unclear, the exclusion is what suffers, because the default under the Act is that property owned at separation is family property to be shared.

That single sentence in the statute drives everything about how a tracing file is run. It is not enough to remember where the money came from. You have to show it.

How an Exclusion Follows the Money

Section 85(1)(g) extends an exclusion to property derived from excluded property, or from its disposition. That is what makes tracing possible. An inheritance can become a term deposit, then a down payment, then equity in the next house, and the exclusion can survive every step, as long as each step can be shown.

A clean trace reads like a chain: the estate cheque deposited on one statement, the transfer out on the next, the conveyancing record showing where it went. A weak trace has gaps where the money passed through busy accounts, changed shape without records, or arrived at its destination years later with nothing connecting the ends. Our job is to close those gaps while the records still exist.

The Evidence Work We Do

Tracing is an evidence project, and we run it like one:

• Map the path first. We interview you, sketch the route the money took, and identify every account, property and transaction on that route.
• Collect the records. Bank and investment statements, estate documents, gift letters, land title records, mortgage payout statements and conveyancing files. Where your own copies are gone, we request them from institutions, and we move quickly because retention periods are limited.
• Anchor the starting value. For pre-relationship assets, the value when the relationship began matters because growth during the relationship is generally shared. Old assessments, statements and appraisals set that anchor.
• Press for disclosure. Both sides must lay out their finances. Full disclosure, including the other spouse's records, is often what completes a chain, which is why we treat financial disclosure as the foundation of the file. Our post on the importance of disclosure in family law matters explains what happens when it is thin.
• Present the trace. We put the chain into a schedule a mediator, opposing counsel or judge can follow line by line. A trace nobody can follow persuades nobody.

Commingling and Why It Raises the Stakes

Commingling means excluded money getting mixed with shared money, most often in a joint account that also receives pay cheques and pays the bills. The Act does not say a mixed exclusion is lost. What changes is the evidence problem. Once funds are blended, showing how much of what remains is still the excluded money gets harder, and section 85(2) keeps that burden on you the whole way.

So we frame commingling for clients as an evidence-burden outcome, not a fixed rule. The more mixing, and the fewer records, the heavier the burden gets, and the more the result depends on what can still be reconstructed. Some blended traces can be rebuilt from statements. Others cannot. Which side of that line you are on is exactly what the tracing work finds out.

What Did Mills v. O'Connor Change About Tracing?

In Mills v. O'Connor, 2025 BCCA 34, the British Columbia Court of Appeal gave its first specific guidance on tracing excluded property that has been co-mingled with family property. The court rejected first-in-first-out reasoning, which quietly assumes the excluded money survived every transaction intact, and adopted pro rata tracing as the general rule: the excluded value and the family-property value that were blended are treated as proportionate contributions to one mixed pool, and whatever remains is attributed in those same proportions. The court also stressed that tracing should stay flexible, so a different method may occasionally produce the fairest result. One reassuring point from the decision: pro rata tracing only reduces an exclusion below its original value where the mixed pool has dropped in value. Our plain-language walkthrough of the decision is here: tracing an inheritance mixed with family property.

What Records Should I Start Gathering Now?

Start with the two ends of the chain, then fill the middle:

• statements from the month the inheritance or gift arrived, and estate or gift documents showing the amount
• account statements from the start of the relationship for anything you brought in
• records for every account the money touched afterward
• purchase and sale documents for any property it went into

If you are separating now, our guide to separating your finances covers the wider record-gathering job, and the earlier it starts the more of the trail survives.

Can Tracing Still Work Years Later?

Sometimes, but the odds worsen with time. Institutions keep records for limited periods, accounts get closed, and memories fade. If you received an inheritance or brought significant property into your relationship, the useful moment to preserve the records is now, not at separation. A written agreement can also lock in what is excluded while the facts are fresh, which is often cheaper than a tracing fight later.

Is Tracing Only for Court Cases?

No. Most of our tracing work supports negotiation and mediation, not trials. A documented trace changes settlement discussions because the other side can see what a judge would see. The result usually lands in a separation agreement rather than a courtroom, and that is the outcome we aim for. See our property division services for the full picture of how these files run.
