Suspicion is not evidence, and the gap between them is where most of this goes wrong. Here is how to close it.
| Start with the gaps, not the theory | What was requested, what arrived, and what is missing — item by item. |
|---|---|
| The strongest evidence | Documents that do not reconcile. A lifestyle that does not match a declared income. A gap in a statement sequence. |
| What almost never works | Asserting that they are hiding something, without specifics. |
| The response to avoid | Withholding your own disclosure. It turns their problem into a shared one. |
| Mechanisms exist | Orders compelling production, undertakings, follow-up requests. What is available depends on your jurisdiction. |
| When a forensic accountant is worth it | When the amount at stake exceeds the cost by a comfortable margin, and there is something concrete to investigate. |
| The long game | Material non-disclosure discovered later can be a route to reopening a settlement. |
Keeping track of dates like these across a stack of letters is exactly what SortMyDivorce does — start a free trial, no card needed.
The single most useful move is unglamorous: go through the disclosure request item by item and produce a list.
For each category: what was asked for, what arrived, and what is missing or partial. Not "their disclosure is incomplete" but "items 6, 8 and 11 were not provided; the bank statements skip March; the 2024 corporate financials are unsigned."
That list is what a lawyer can act on. An impression is not.
Some things are far more persuasive than others.
Sequence gaps. Bank or credit card statements missing a month. Statements that start after a significant date. These are noticeable and they are hard to explain away.
Figures that do not reconcile. A tax return that does not match a bank deposit pattern. A corporate financial statement that does not match a personal declaration. Transfers out to accounts that do not appear on the asset list.
A lifestyle that does not match a declared income. Spending, travel or purchases inconsistent with what is being declared. This is the classic, and it is genuinely persuasive when documented rather than asserted.
Structural opacity. Income routed through a corporation, a partnership or a trust. This is not evidence of anything by itself — many people legitimately run their affairs this way — but it is where scrutiny is warranted, and it is where the fight usually is.
Timing. Assets sold, transferred or restructured shortly before or after separation.
Documents that were promised and never arrived. Where an undertaking was given at questioning, this is stronger still — an undertaking binds the lawyer personally and its non-answer is documented in a transcript.
Asserting bad faith without specifics. It is easy to say and impossible to act on, and it costs you credibility on the points where you are right.
Relying on what you remember. "There was an account at X" is a start, not evidence. If you have a statement, a letter, a transfer record — that is different.
Obtaining material improperly. Accessing accounts, email or devices you are not authorised to access can be a serious problem in itself, potentially criminal, and it can taint the material. Ask your lawyer before doing anything to obtain information you do not already have lawful access to.
Withholding your own disclosure in response. Understandable and consistently counterproductive. It converts a situation where one party is non-compliant into one where both are, and it removes the asymmetry that was working in your favour.
What is available depends entirely on your jurisdiction, and this guide deliberately does not state what applies where. Broadly, the escalation looks like:
A specific written request. Naming exactly what is missing. Often this is enough.
A formal disclosure demand. Many jurisdictions have a mechanism — Alberta's Notice to Disclose is one, with a one-month compliance period.
An order compelling production. Where the demand is not met. In Alberta, since May 2020, a Disclosure Order can be sought by desk application — by email, decided on the papers, without a hearing — which materially lowers the cost of escalating.
Questioning, and undertakings. Being asked under oath about the gaps, with promises to produce recorded in a transcript.
Third-party production. Obtaining records directly from a bank, employer or other institution, where the rules permit.
Expert investigation. A forensic accountant.
Ask your lawyer which of these apply to you and in what order. There is usually a proportionate next step that is cheaper than the one people imagine.
They are expensive, and they are worth it in a narrow set of circumstances: where there is a business, a corporation or a trust involved; where the amount genuinely at stake comfortably exceeds the cost; and where there is something concrete to investigate rather than a general unease.
They are usually not worth it where the assets are straightforward — salary, a house, ordinary accounts — or where the suspicion has no anchor. A general instruction to "find out if anything is hidden" is the most expensive way to buy an answer you may not like.
Ask your lawyer for an estimate and a view on proportionality before instructing anyone.
One thing worth knowing, because it changes how it feels to be in this position.
Material non-disclosure that surfaces later is one of the recognised routes to challenging a concluded agreement. Settling on the basis of a picture that turns out to have been incomplete is not necessarily the end of the matter.
That is not a reason to settle carelessly or to stop pressing now — reopening a settlement is expensive, slow and uncertain, and it is far better to get the disclosure before signing. But it does mean the other side is taking a real risk, and it is worth understanding that the incentive runs against them.
Verification note. This guide is deliberately structural. The mechanisms for compelling disclosure, the consequences of non-disclosure, and the grounds on which a concluded agreement may be reopened for material non-disclosure all differ by jurisdiction and none was verified against a primary source here other than the Alberta material cited. Confirm what applies to you with your own lawyer.
Tell your lawyer exactly what you know and how you know it. That can be enough to frame a specific request or a question at questioning — and a specific question is much harder to deflect than a general one.
Ask your lawyer first. Accessing accounts, devices or correspondence you are not authorised to access can be a serious problem, including a criminal one, and it can taint material that would otherwise have been useful.
Then the question becomes specific: which item, and what is the gap? A sworn statement that turns out to be incomplete is a materially worse position for them than an argument about scope. Work item by item.
It varies widely with scope. Get an estimate before instructing, and weigh it against what is genuinely in dispute.
That is a strategic question for your lawyer. Sometimes a specific, calm, documented request produces the material. Sometimes it produces a warning. The answer depends on the facts.
That happens, and it is not a disaster if you have proceeded by asking specific questions rather than by making accusations. This is another argument for working from the gap list rather than from the theory.
