Claiming that a gift or inheritance is excluded from equalization is the easy part. Proving it — to a skeptical spouse, a mediator, or a judge — is where many claims quietly fall apart. Ontario law lets spouses keep certain property out of the equalization calculation, but the person claiming the exclusion has to show it.
Proving an exclusion claim comes down to one thing: an unbroken paper trail from the original gift or inheritance to the asset you hold today. Without it, a court has little to work with beyond your word.
This guide sets out what that evidence looks like and how to start building it.
What "Proving" an Exclusion Actually Means
The spouse who wants an asset treated as excluded generally carries the burden of establishing it — not the other way around. That means gathering evidence that shows, first, that the property genuinely came from a gift or inheritance from someone other than your spouse, and second, that it (or whatever it turned into) can still be traced to that original source today.
Vague recollection ("my aunt gave me some money years ago") rarely carries the day on its own. Documentation does.
The Paper Trail You Need
| Document type | What it proves |
|---|---|
| Will, estate statement, or letter from the estate trustee | The money genuinely came from an inheritance, and roughly when and how much |
| A dated gift letter, card, or written confirmation from the giver | The transfer was a gift, not a loan or repayment, and identifies who gave it |
| Bank or brokerage statements from the date of receipt onward | An unbroken record of where the funds sat and moved over time |
| Statements showing the funds were never mixed with joint accounts | The property stayed identifiable and separate |
| Records of any sale, reinvestment, or transfer | How the original property was traced into its current form |
Step-by-Step: Building Your Claim
- Gather the original source documents. Start with the will, estate correspondence, or gift letter that shows where the money or property came from.
- Trace the funds through every account they touched. Pull statements covering the full period from receipt to today, even if that means requesting old records from a bank.
- Separate what’s traceable from what got mixed. Be honest about where commingling happened — a partial exclusion, supported by what you can prove, is more credible than an overstated claim you can’t back up.
- Get a professional accounting opinion if the picture is complex. Where funds moved through several accounts or investments over years, a forensic accountant can sometimes reconstruct a trail that raw statements alone don’t make obvious.
- Bring it to a lawyer early — ideally at separation, not years later. Memories fade, banks purge old records, and the sooner the trail is documented, the stronger the claim.
When the Trail Is Incomplete
Few people keep perfect records for a gift or inheritance received years, sometimes decades, before a separation. When documentation is thin:
- Courts work with the best evidence available, not a demand for perfection.
- A partial trail can sometimes support a partial exclusion, even where the full amount can’t be proven.
- Cash gifts, older inheritances, and funds that passed through several accounts tend to be the hardest to reconstruct — start there first if you’re gathering records now.
- The absence of a paper trail doesn’t automatically defeat a claim, but it shifts real risk onto the spouse trying to prove it.
Frequently asked questions
What if I never kept any records?
Start by contacting the source directly — an estate trustee, a bank, or a family member who made the gift — as records often exist even when you don’t personally have them. A lawyer can also advise on what secondary evidence, like affidavits from people involved, might help fill gaps.
Does my spouse have to accept my claim, or does a court decide?
If your spouse agrees the property is excluded, it can simply be reflected in a separation agreement. If they don’t, the question is ultimately decided by a court (or resolved through negotiation or mediation beforehand) based on the evidence each side puts forward.
Can a family member confirm a gift was really a gift?
A written or sworn statement from the person who made the gift can help, particularly where there’s a dispute about whether money was a gift versus a loan that was expected to be repaid.
How far back do I need records?
Ideally, from the date you received the property through to your separation. Older gifts and inheritances are harder to document, which is exactly why gathering whatever records still exist sooner rather than later matters.
